Easier Information Exchange Strengthens Emergency Response [21Sep11] - 0 views

  • A nuclear or radiological emergency presents complex public health, environmental and engineering challenges. A constant flow of detailed, reliable information is indispensable to be able to marshal and coordinate the needed response which includes the prompt mobilisation and dispatch of specialised human and equipment resources, as requested. The global focal point for such coordination and information exchange is the IAEA's Incident and Emergency Centre, or IEC. It is the IEC's task to inform many different official designated actors around the world as quickly as possible whenever a nuclear or radiological emergency occurs. A sustained and reliable information flow is one of the most important resources in effective incident and emergency response. New Platform
  • One of the IEC's tasks is to develop and improve the communication and coordination systems that deliver authenticated and verified information to the emergency responders who need it. During the emergency response to the Fukushima Daiichi Nuclear Power Plant accident, the IEC launched a new, secure web-based communications platform, the Unified System for Information Exchange on Incidents and Emergencies, or USIE. The new system, which had been in development since 2009, replaces two existing communication systems, thus simplifying the emergency information exchange. "The new USIE system delivers a solution the emergency response community needed and requested from the IAEA," said Denis Flory, IAEA Deputy Director General for Nuclear Safety and Security. "When the IAEA's Member States respond to a nuclear incident or emergency, they need a single, secure, straight-forward system that easily adapts to their needs. That is exactly what USIE does."
  • Alert System Like its predecessor systems, USIE is a secure website to which registered users have access. Instead of monitoring two separate systems that previously reported on different types of incidents, users now receive alerts from the new USIE system when new information is issued about any type of incident, ranging from a lost radioactive source to a full-scale nuclear emergency. The platform delivers alerts, based upon the user's preferences, via text messages delivered to a mobile device, or via email, or via fax. The system tracks multiple events, issuing information that has been authenticated by the country reporting an accident or incident. The platform meets demanding security standards thus offering its users the assurance that the information received is reliable.

  • Readiness Preparedness is an essential prerequisite for effective nuclear emergency management. International exercises are held systematically to determine whether the national systems in place are prepared and can respond swiftly and effectively. The USIE system is designed to support such exercises. "For the first time, this simple-to-use and effective system streamlines mechanisms for reporting and sharing information about incidents and emergencies in a secure information exchange channel," said Elena Buglova, the Head of the IAEA's Incident and Emergency Centre. This innovation strengthens international coordination, she noted, "which will improve the speed and effectiveness of the global response to nuclear and radiological emergencies of all types."
  • Background
  • Until the Chernobyl nuclear accident in 1986, there was no information exchange system. Immediately following that accident, the IAEA's Member States negotiated the so-called Emergency Conventions to ensure that in the event of a nuclear accident, the country that suffers an accident would issue timely, authenticated information, while the Member States that could field technical support, would do so in a coordinated fashion, if such support is requested by the State concerned. When concerns regarding the malicious use of nuclear or radioactive materials grew, the IAEA established the IEC in 2005 to serve as a global focal point for emergency preparedness and response to nuclear and radiological incidents and emergencies. The IEC develops standards, guidelines and tools like USIE. The IEC staff provide support, training, global event reporting, information exchange and around-the-clock assistance to Member States dealing with nuclear and radiological events. Fundamentally, the IEC is a global coordinator for international expertise from the IAEA, as well as from other international organizations, such as the FAO, WHO, or WMO.
  • Before USIE's launch in June 2011, two secure websites were operated to provide emergency and support information: The Emergency Notification and Assistance Convention Website, or ENAC, was set up to exchange information on nuclear accidents or radiological emergencies. The Nuclear Event Web-based System, or NEWS, is a joint project of the IAEA, OECD/NEA and World Association of Nuclear Operators that provides authoritative information on nuclear and radiological events, using the International Nuclear and Radiological Event Scale, or INES. See Story Resources for more information.

Programmer of Fukushima confesses "Fukushima had a cyber attack" [05Dec11] - 0 views

  • A computer engineer found out operating system of Fukushima plants have been attacked and those attacks were mostly from / via Russia. This engineer is counted as one of the members of Fukushima 50. They installed the system about 6 years ago. It means: someone / some organizations have been attacking the system since 6 years ago. The engineer was called by JP government on 3/14/2011. He was the developer of the system in Fukushima. He was in Tokyo but taken to Fukushima plants by the helicopter of Japan Ground Self-Defense Force. His mission was to reboot the auto operating system and re-start it as manual mode.
  • Because the system was shut down after black out they could not operate the systems to control the pressure, water injecting, radiation shield etc. and that had to be done by him. He managed to reboot the system and restart it in manual mode but he encountered series of troubles such as password entry screen did not come out or his password entering was disturbed by compute bug. He sorted it out by formatting the system but it was obvious that someone sent virus to the system. He tried to send virus backward and it reached to Russia. Someone sent virus from or via Russia. He asked to staff from JP government about what is going on but they did not tell him anything in the name of “confidential”.

German Nuclear Decommissioning and Renewables Build-Out [23Oct11] - 0 views

  • Germany will be redirecting its economy towards renewable energy, because of the political decision to decommission its nuclear plants, triggered by the Fukushima event in Japan and subsequent public opposition to nuclear energy. Germany's decision would make achieving its 2020 CO2 emission reduction targets more difficult.   To achieve the CO2 emissions reduction targets and replace nuclear energy, renewable energy would need to scale up from 17% in 2010 to 57% of total electricity generation of 603 TWh in 2020, according to a study by The Breakthrough Institute. As electricity generation was 603 TWh in 2010, increased energy efficiency measures will be required to flat-line electricity production during the next 9 years.   Germany has 23 nuclear reactors (21.4 GW), 8 are permanently shut down (8.2 GW) and 15 (13.2 GW) will be shut down by 2022. Germany will be adding a net of 5 GW of coal plants, 5 GW of new CCGT plants and 1.4 GW of new biomass plants in future years. The CCGT plants will reduce the shortage of quick-ramping generation capacity for accommodating variable wind and solar energy to the grid.
  • Germany is planning a $14 billion build-out of transmission systems for onshore and future offshore wind energy in northern Germany and for augmented transmission with France for CO2-free hydro and nuclear energy imports to avoid any shortages.    Germany had fallen behind on transmission system construction in the north because of public opposition and is using the nuclear plant shutdown as leverage to reduce public opposition. Not only do people have to look at a multitude of 450-ft tall wind turbines, but also at thousands of 80 to 135 ft high steel structures and wires of the transmission facilities.   The $14 billion is just a minor down payment on the major grid reorganization required due to the decommissioning of the nuclear plants and the widely-dispersed build-outs of renewables. The exisitng grid is mostly large-central-plant based. 
  • This article includes the estimated capital costs of shutting down Germany's nuclear plants, reorganizing the grids of Germany and its neighbors, and building out renewables to replace the nuclear energy.    Germany’s Renewable Energy Act (EEG) in 2000, guarantees investors above-market fees for solar power for 20 years from the point of installation. In 2010, German investments in  renewables was about $41.2 billion, of which about $36.1 billion in 7,400 MW of solar systems ($4,878/kW). In 2010, German incentives for all renewables was about $17.9 billion, of which about half was for solar systems.   The average subsidy in 2010 was about ($9 billion x 1 euro/1.4 $)/12 TWh = 53.6 eurocents/kWh; no wonder solar energy is so popular in Germany. These subsidies are rolled into electric rates as fees or taxes, and will ultimately make Germany less competitive in world markets.   http://thebreakthrough.org/blog//2011/06/analysis_germanys_plan_to_phas-print.html http://mobile.bloomberg.com/news/2011-05-31/merkel-faces-achilles-heel-in-grids-to-unplug-german-nuclear.html http://www.theecologist.org/News/news_analysis/829664/revealed_how_your_country_compares_on_renewable_investment.html http://en.wikipedia.org/wiki/Solar_power_in_Germany

  • SUMMARY OF ESTIMATED CAPITAL AND OTHER COSTS   The estimated capital costs and other costs for decommissioning the nuclear plants, restoring the sites, building out renewables, wind and solar energy balancing plants, and reorganizing electric grids over 9 years are summarized below.    The capital cost and subsidy cost for the increased energy efficiency measures was not estimated, but will likely need to be well over $180 billion over 9 years, or $20 billion/yr, or $20 b/($3286 b in 2010) x 100% = 0.6% of GDP, or $250 per person per yr.     Decommission nuclear plants, restore sites: 23 @ $1 billion/plant = $23 billion Wind turbines, offshore: 53,300 MW @ $4,000,000/MW = $213.2 billion   Wind turbines, onshore: 27,900 MW @ $2,000,000/MW = $55.8 billion Wind feed-in tariff extra costs rolled into electric rates over 9 years: $200 billion  Solar systems: 82,000 MW @ $4,500,000/MW = $369 billion Solar feed-in tariff extra costs rolled into electric rates over 9 years = $250 billion. Wind and solar energy balancing plants: 25,000 MW of CCGTs @ $1,250,000/MW = $31.3 billion Reorganizing European elecric grids tied to German grids: $150 billion
  • RENEWABLE ENERGY AND ENERGY EFFICIENCY TARGETS   In September 2010 the German government announced the following targets:   Renewable electricity - 35% by 2020 and 80% by 2050 Renewable energy - 18% by 2020, 30% by 2030, and 60% by 2050 Energy efficiency - Reducing the national electricity consumption 50% below 2008 levels by 2050.  http://en.wikipedia.org/wiki/Renewable_energy_in_Germany   Germany has a target to reduce its nation-wide CO2 emissions from all sources by 40% below 1990 levels by 2020 and 80-85% below 1990 levels by 2050. That goal could be achieved, if 100% of electricity is generated by renewables, according to Mr. Flasbarth. Germany is aiming to convince the rest of Europe to follow its lead.
  • Biomass: At the end of 2010, about 5,200 MW of biomass was installed at a capital cost of about $18 billion. Biomass energy produced was 33.5 TWh, or 5.5% of production. Plans are to add 1,400 MW of biomass plants in future years which, when fully implemented, would produce about 8.6 TWh/yr.   Solar: At the end of 2010, about 17,320 MW of PV solar was installed in Germany at a capital cost of about $100 billion. PV solar energy produced was 12 TWh, or 2% of total production. The excess cost of the feed-in-tariff energy bought by utilities and rolled into the electricity costs of rate payers was about $80 billion during the past 11 years.   Most solar panels are in southern Germany (nation-wide solar CF 0.095). When skies are clear, the solar production peaks at about 7 to 10 GW. Because of insufficient capacity of transmission and quick-ramping gas turbine plants, and because curtailment is not possible, part of the solar energy, produced at a cost to the German economy of about 30 to 50 eurocent/kWh is “sold” at European spot prices of about 5 eurocent/kWh to France which has significant hydro capacity for balancing the variable solar energy. http://theenergycollective.com/willem-post/46142/impact-pv-solar-feed-tariffs-germany  
  • Wind: At the end of 2010, about 27,200 MW of onshore and offshore wind turbines was installed in Germany at a capital cost of about $50 billion. Wind energy produced was 37.5 TWh, or 6.2% of total production. The excess cost of the feed-in-tariff energy bought by utilities and rolled into electricity costs of rate payers was about $50 billion during the past 11 years.   Most wind turbines are in northern Germany. When wind speeds are higher wind curtailment of 15 to 20 percent takes place because of insufficient transmission capacity and quick-ramping gas turbine plants. The onshore wind costs the Germany economy about 12 eurocent/kWh and the offshore wind about 24 eurocent/kWh. The owners of the wind turbines are compensated for lost production.   The alternative to curtailment is to “sell” the energy at European spot prices of about 5 eurocent/kWh to Norway and Sweden which have significant hydro capacity for balancing the variable wind energy; Denmark has been doing it for about 20 years.   As Germany is very marginal for onshore wind energy (nation-wide onshore wind CF 0.167) and nearly all of the best onshore wind sites have been used up, or are off-limits due to noise/visual/environmental impacts, most of the additional wind energy will have to come from OFFSHORE facilities which produce wind energy at about 2 to 3 times the cost of onshore wind energy. http://theenergycollective.com/willem-post/61774/wind-energy-expensive
  • A 2009 study by EUtech, engineering consultants, concluded Germany will not achieve its nation-wide CO2 emissions target; the actual reduction will be less than 30%. The head of Germany's Federal Environment Agency (UBA), Jochen Flasbarth, is calling for the government to improve CO2 reduction programs to achieve targets. http://www.spiegel.de/international/germany/0,1518,644677,00.html   GERMAN RENEWABLE ENERGY TO-DATE   Germany announced it had 17% of its electrical energy from renewables in 2010; it was 6.3% in 2000. The sources were 6.2% wind, 5.5% biomass, 3.2% hydro and 2.0% solar. Electricity consumption in 2010 was 603 TWh (production) - 60 TWh (assumed losses) = 543 TWh http://www.volker-quaschning.de/datserv/ren-Strom-D/index_e.php  
  • Hydro: At the end of 2010, about 4,700 MW of hydro was installed. Hydro energy produced was 19.5 TWh, or 3.2% of production. Hydro growth has been stagnant during the past 20 years. See below website.   As it took about $150 billion of direct investment, plus about $130 billion excess energy cost during the past 11 years to achieve 8.2% of total production from solar and wind energy, and assuming hydro will continue to have little growth, as was the case during the past 20 years (almost all hydro sites have been used up), then nearly all of the renewables growth by 2020 will be mostly from wind, with the remainder from solar and biomass. http://www.renewableenergyworld.com/rea/news/article/2011/03/new-record-for-german-renewable-energy-in-2010??cmpid=WNL-Wednesday-March30-2011   Wind and Solar Energy Depend on Gas: Wind and solar energy is variable and intermittent. This requires quick-ramping gas turbine plants to operate at part-load and quickly ramp up with wind energy ebbs and quickly ramp down with wind energy surges; this happens about 100 to 200 times a day resulting in increased wear and tear. Such operation is very inefficient for gas turbines causing them to use extra fuel/kWh and emit extra CO2/kWh that mostly offset the claimed fuel and CO2 reductions due to wind energy. http://theenergycollective.com/willem-post/64492/wind-energy-reduces-co2-emissions-few-percent  
  • Wind energy is often sold to the public as making a nation energy independent, but Germany will be buying gas mostly from Russia supplied via the newly constructed pipeline under the Baltic Sea from St. Petersburg to Germany, bypassing Poland.   GERMANY WITHOUT NUCLEAR ENERGY   A study performed by The Breakthrough Institute concluded to achieve the 40% CO2 emissions reduction target and the decommissioning of 21,400 MW of nuclear power plants by 2022, Germany’s electrical energy mix would have to change from 60% fossil, 23% nuclear and 17% renewables in 2010 to 43% fossil and 57% renewables by 2020. This will require a build-out of renewables, reorganization of Europe’s electric grids (Europe’s concurrence will be needed) and acceleration of energy efficiency measures.   According to The Breakthrough Institite, Germany would have to reduce its total electricity consumption by about 22% of current 2020 projections AND achieve its target for 35% electricity generated from renewables by 2020. This would require increased energy efficiency measures to effect an average annual decrease of the electricity consumption/GDP ratio of 3.92% per year, significantly greater than the 1.47% per year decrease assumed by the IEA's BAU forecasts which is based on projected German GDP growth and current German efficiency policies.
  • The Breakthrough Institute projections are based on electricity consumption of 544  and 532 TWh  in 2008 and 2020, respectively; the corresponding production is 604 TWh in 2008 and 592 TWh in 2020.   http://thebreakthrough.org/blog//2011/06/analysis_germanys_plan_to_phas-print.html http://www.iea.org/textbase/nppdf/free/2007/germany2007.pdf   Build-out of Wind Energy: If it is assumed the current wind to solar energy ratio is maintained at 3 to 1, the wind energy build-out will be 80% offshore and 20% onshore, and the electricity production will be 592 TWh, then the estimated capital cost of the offshore wind turbines will be [{0.57 (all renewables) - 0.11 (assumed biomass + hydro)} x 592 TWh x 3/4] x 0.8 offshore/(8,760 hr/yr x average CF 0.35) = 0.0533 TW offshore wind turbines @ $4 trillion/TW = $213 billion and of the onshore wind turbines will be [{0.57 (all renewables) - 0.11 (assumed biomass + hydro)} x 592 TWh x 3/4] x 0.2 onshore/(8,760 hr/yr x average CF 0.167) = 0.279 TW of wind turbines @ $2 trillion/TW = $56 billion, for a total of $272 billion. The feed in tariff subsidy for 9 years, if maintained similar to existing subsidies to attract adequate capital, will be about $150 billion offshore + $50 billion onshore, for a total of $200 billion.    
  • Note: The onshore build-out will at least double Germany’s existing onshore wind turbine capacity, plus required transmission systems; i.e., significant niose, environmental and visual impacts over large areas.   Recent studies, based on measured, real-time, 1/4-hour grid operations data sets of the Irish, Colorado and Texas grids, show wind energy does little to reduce CO2 emissions. Such data sets became available during the past 2 to 3 years. Prior studies, based on assumptions, estimates, modeling scenarios, and statistics, etc., significantly overstate CO2 reductions.  http://theenergycollective.com/willem-post/64492/wind-energy-reduces-co2-emissions-few-percent   Build-out of PV Solar Energy: The estimated capital cost of the PV solar capacity will be [{0.57 (all renewables) - 0.11 (assumed biomass + hydro)} x 592 TWh x 1/4]/(8,760 hr/yr x average CF 0.095) = 0.082 TW @ $4.5 trillion/TW = $369 billion. The feed in tariff subsidy, if maintained similar to existing subsidies to attract adequate capital, will be about $250 billion.   Reorganizating Electric Grids: For GW reasons, a self-balancing grid system is needed to minimize CO2 emissions from gas-fired CCGT balancing plants. One way to implement it is to enhance the interconnections of the national grids with European-wide HVDC overlay systems (owning+O&M costs, including transmission losses), and with European-wide selective curtailment of wind energy, and with European-wide demand management and with pumped hydro storage capacity. These measures will reduce, but not eliminate, the need for balancing energy, at greater wind energy penetrations during high-windspeed weather conditions, as frequently occur in Iberia (Spain/Portugal).  
  • European-wide agreement is needed, the capital cost will be in excess of $150 billion and the adverse impacts on quality of life (noise, visuals, psychological), property values and the environment will be significant over large areas.    Other Capital Costs: The capacity of the quick-ramping CCGT balancing plants was estimated at 25,000 MW; their capital cost is about 25,000 MW x $1,250,000/MW = $31.3 billion. The capital costs of decommissioning and restoring the sites of the 23 nuclear plants will be about $23 billion.   Increased Energy Efficiency: Increased energy efficiency would be more attractive than major build-outs of renewables, because it provides the quickest and biggest "bang for the buck", AND it is invisible, AND it does not make noise, AND it has minimal environmental impact, AND it usually reduces at least 3 times the CO2 per invested dollar, AND it usually creates at least 3 times the jobs per invested dollar, AND it usually creates at least 3 times the energy reduction per invested dollar, AND it does all this without public resistance and controversy.   Rebound, i.e., people going back to old habits of wasting energy, is a concept fostered by the PR of proponents of conspicuous consumption who make money on such consumption. People with little money love their cars getting 35-40 mpg, love getting small electric and heating bills. The rebound is mostly among people who do not care about such bills.
  • A MORE RATIONAL APPROACH   Global warming is a given for many decades, because the fast-growing large economies of the non-OECD nations will have energy consumption growth far outpacing the energy consumption growth of the slow-growing economies of the OECD nations, no matter what these OECD nations do regarding reducing CO2 emissions of their economies.   It is best to PREPARE for the inevitable additional GW by requiring people to move away from flood-prone areas (unless these areas are effectively protected, as in the Netherlands), requiring new  houses and other buildings to be constructed to a standard such as the Passivhaus standard* (such buildings stay cool in summer and warm in winter and use 80 to 90 percent less energy than standard buildings), and requiring the use of new cars that get at least 50 mpg, and rearranging the world's societies for minimal energy consumption; making them walking/bicycling-friendly would be a good start.   If a nation, such as the US, does not do this, the (owning + O&M) costs of its economy will become so excessive (rising resource prices, increased damage and disruptions from weather events) that its goods and services will become less competitive and an increasing percentage of its population will not be able to afford a decent living standard in such a society.   For example: In the US, the median annual household income (inflation-adjusted) was $49,445, a decline of 7% since 2000. As the world’s population increases to about 10 billion by 2050, a triage-style rationing of resources will become more prevalent. http://www.usatoday.com/news/nation/story/2011-09-13/census-household-income/50383882/1
  • * A 2-year-old addition to my house is built to near-Passivhaus standards; its heating system consists of a thermostatically-controlled 1 kW electric heater, set at 500 W, that cycles on/off on the coldest days for less than 100 hours/yr. The addition looks inside and out entirely like standard construction. http://theenergycollective.com/willem-post/46652/reducing-energy-use-houses

Shutdown of Fukushima Reactors Is Ahead of Schedule [Nov11] - 0 views

  • Editor's Note: This is part of the IEEE Spectrum special report: Fukushima and the Future of Nuclear Power.
  • This past April, when the Japanese government and Tokyo Electric Power Co. (TEPCO) jointly unveiled their plan to bring the damaged reactors of the Fukushima Dai-ichi nuclear power plant to a cold shutdown and gain control of the release of radioactive materials, they set a tentative completion date for mid-January 2012. And "tentative" had to be the operative word, for the obstacles TEPCO faced—and to some extent still does face—are challenging in the extreme. They include:
  • Fuel rod meltdowns in reactors 1, 2, and 3 due to loss of cooling systems following the 11 March earthquake and tsunami; Severe damage to the upper levels of reactor buildings 1, 3, and 4 and slight damage to building 2, stemming from hydrogen explosions; High levels of radiation and contaminated rubble, making working conditions hazardous and difficult; Thousands of metric tons of contaminated water accumulating on the site and leaking out of the reactors.
  • ...5 more annotations...
  • Critics, however, were quick to question the stability of the system and its ad hoc design. The combination of filtering and decontamination technologies—mainly from the French nuclear giant Areva and the U.S. nuclear waste management company Kurion—includes some 4 kilometers of piping. The critics have a point. Even with the addition of a reportedly more robust system (to be used in parallel or as backup as needed) from Toshiba and IHI Corp., TEPCO admits the system underwent 39 disruptions between 10 July and 8 September. One consequence is that roughly 100 000 metric tons of water still need to be decontaminated.
  • It appears, however, that the process is now ahead of schedule. Environment Minister Goshi Hosono, who is also in charge of the Fukushima nuclear accident recovery, told the International Atomic Energy Agency's annual general conference in Vienna on 19 September that Japan was now aiming to complete a cold shutdown of the Fukushima plant by December 2011, instead of mid-January 2012. Progress was already evident in July, when Hosono announced that workers had completed step 1 of the two-step road map on schedule, reducing radioactive emissions and starting to bring down the core temperatures in reactors 1, 2, and 3. Hosono attributed the success to the construction of a new cooling system, which had begun pumping water into all three damaged reactors. In addition to cooling, the system also decontaminates the water accumulating in the basements of the reactor and turbine buildings. The contamination is the result of injected water coming into contact with the molten fuel in the pressure vessels.
  • Disruptions and remaining challenges notwithstanding, TEPCO has been making progress toward step 2 of the road map: a cold shutdown. According to TEPCO, that means achieving and maintaining a temperature of less than 100 °C as measured at the bottom of a reactor pressure vessel—the steel vessel containing the fuel rods—which itself is enclosed inside a protective containment vessel. A major advance came at the beginning of September, when TEPCO was able to start up the core spray lines to cool reactors 1 and 3. The core spray lines apply water directly to the cores from above, while the system installed in July has been cooling the cores by injecting water from the bottom. TEPCO has also begun increasing the amount of water being injected into reactor 2. The core spray line could not be used until recently because TEPCO first had to survey the subsystem's piping and valves. Given the high radiation in the area, this was difficult, but workers completed the job in July and confirmed the system's operability in August.
  • By late September, as a result of these efforts, the temperatures in all three reactors had dropped below 100 °C for the first time since the accident. As of 29 September, the temperatures for reactors 1, 2, and 3, respectively, were 77.5 °C, 99.7 °C, and 78.7 °C. "We are steadily bringing the postaccident situation under control," says Hosono. "To achieve step 2 this year, we'll move the schedule forward and do our best." But Yoshinori Moriyama, deputy director-general of Japan's Nuclear and Industrial Safety Agency (NISA) is cautious. "We need to maintain this state over the midterm," he says. "Temporary lower temperatures and the nonrelease of radioactive substances do not immediately mean that this is a cold shutdown." In order for NISA to declare a cold shutdown, the temperatures must remain stable and below 100 °C into December. So NISA won't officially declare a cold shutdown until near the end of 2011.
  • Despite these positive developments, nuclear experts point out that achieving a cold shutdown does not make the troubled plant completely safe, given that even spent fuel continues to generate heat for years after use. And upon achieving a cold shutdown, TEPCO must take on a new series of challenges. These include finding where the injected water is escaping, stopping those leaks, dealing with the accumulated contaminated water, removing and storing the thousands of spent fuel rods from the pools in reactors 1 to 4, and then figuring out a way to remove the melted fuel. The last is a task that could take a decade or more, according to experts.

Actual Fukushima worker talks ,water purifying system has never worked [06Dec11] - 0 views

  • Following up this article http://fukushima-diary.com/2011/12/220t-of-highly-radioactive-water-leaked-and-a-part-of-it-leaked-to-the-sea/ The water purifying system has never worked properly. It was urgently constructed , the whole system can’t stand anymore. These are the tweets of actual Fukushima worker ,Happy20790. He explains how it is on the sight.
  • <Translation> The contaminated water leaks a lot recently. This time ,it went out of the “building” so it was reported but actually it happens frequently. I called it “a building” ,but it’s actually a temporary tent on a temporary concrete basement. It leaked from the first operation ,so they made a tiny dam in it. Maybe it’s only 20cm high. I don’t get into the tent recently because it’s too radioactive,but I used to pump up leaked contaminated water. The contaminated water emits a lot of beta ray ,so you need to be careful. This time ,Tepco’s spokes man said it was 110mSv/h ,but it is higher at some points. The concrete basement was constructed really urgently. They built the tent even before the concrete dried. so it got cracked already. Other tent may have the same problems too. Unlike our ordinary contract ,makers only set the facility ,they don’t take responsibility of handing or maintenance. As I tweeted before,this water purifying system is not a long-lasting system. It is a temporary system without proper planning process. In order to release cooling water to the sea ,we must install more proper facility. Now the gutter is straightly connected to the sea. They must be shut down or a dam must be made. Currently every time it rains, radiation on the ground and radiation stuck to the plants flow into the sea straightly. Makers and workers are already withdrawing from Fukushima plants ,but Tepco has no long term plan. They need to predict the future risk and prevent it from happening in advance.

#Fukushima I Nuke Plant: TEPCO Stopped Water Treatment System [17Jun11] - 1 views

  • TEPCO announced on June 18 that it stopped the water treatment system for the highly contaminated water at Fukushima I Nuclear Power Plant at 12:54AM on June 18.
  • ted water at Fukushima I Nuclear Power Plant at 12:54AM on Jun
  • The stoppage was not due to system malfunction, TEPCO explained. The company stopped the system when the radiation level of the cesium absorption subsystem [by Kurion] had reached the set limit earlier than expected. TEPCO had planned to start the cooling water circulation system whereby the treated water is injected back into the Reactor Pressure Vessels on June 18, but it is not clear whether it will start as scheduled.

There are 4 rows of 6 cylinders that contain cesium absorption material [zeolite], and when the radiation level reaches 4 millisieverts/hour the cylinders are to be replaced. According to TEPCO, the system started the full run at 8PM on June 17, but the worker who was remote-operating the system noticed that the radiation measurement device on the surface of the cesium absorption cylinders was 4.7 millisieverts/hour.

#Fukushima I Nuke Plant: 450 Tonnes of Groundwater Per Day Seeping into Reactor/Turbine... - 0 views

  • Since the end of June when the contaminated water treatment system started the operation, total 50,000 tonnes of groundwater have seeped into the reactor buildings and turbine buildings at Fukushima I Nuke Plant. Now, the total amount of contaminated water (highly contaminated water plus not-so-highly contaminated, treated water) at the plant has grown from 127,000 tonnes at the end of June to 175,000 tonnes as of October 18, according to Asahi Shinbun.Does TEPCO have any plan to stop the flow of groundwater into the reactor buildings and turbine buildings, which just adds to the amount of highly contaminated water to be treated and stored? TEPCO is fast running out of storage space, even with cutting down more trees to make room for the storage tanks.Other than spraying the low-contamination, treated water on the premise, the answer is no. No plan, as TEPCO is running out of money that it is willing to spend on Fukushima I Nuke Plant.From Asahi Shinbun (10/19/2011):
  • It has been discovered that the contaminated water has increased by 40% in 4 months inside the reactor buildings and turbine buildings at Fukushima I Nuclear Power Plant, with the inflow of ground water of about 50,000 tonnes. The flow still continues. TEPCO may run out of storage space for the treated, still-contaminated, water. There is also a possibility of the highly contaminated water overflowing from the buildings if a problem at the water treatment facility and a heavy rain coincide.
  • According to the calculation done by Asahi Shinbun based on the data published by TEPCO, about 450 tonnes of ground water per day have been flowing into the buildings of Reactors 1 through 4 since the end of June when the contaminated water treatment facility started the operation. It is considered that there are damages in the walls of the buildings.
  • ...7 more annotations...
  • The amount of groundwater into the buildings fluctuates with the rainfall. At the end of September when it rained heavily because of a typhoon, the amount of ground water doubled, and about 7,700 tonnes of water seeped into the buildings in that week.
  • The groundwater would mix with the contaminated water in the basement of the buildings, and this highly contaminated water is being sent to the water treatment facility. After the density of radioactive materials in the water is lowered and salt removed, the treated water is being used for cooling the reactors.
  • When the circulatory water injection and cooling system started in late June, there were 127,000 tonnes of contaminated water (highly contaminated water plus the treated water with low contamination). However, as the result of the groundwater inflow, there are now 175,000 tonnes of contaminated water, a 40% increase, as of October 18. None of the water could be released outside the plant.
  • Concentrated, highly saline waste water after the desalination process is stored in the special tanks. As more water is processed, more tanks are needed. TEPCO is installing 20,000 tonnes storage tanks every month. To secure the space for the tanks the company has been cutting down the trees in the plant compound. There is a system to evaporate water to reduce the amount of waste water, but it is not currently used.
  • The water level in the turbine buildings where the highly contaminated water after the reactor cooling accumulates is 1 meter below the level at which there is a danger of overflowing. It is not the level that would cause immediate overflow after a heavy rain. However, if the heavy rain is coupled with a trouble at the water treatment system that hampers the water circulation, the water level could rise very rapidly.
  • The treatment capacity of the water treatment facility is 1,400 tonnes per day. TEPCO emphasizes that the facility is running smoothly and the circulatory water injection system is stable. However, if the current situation continues where groundwater keeps coming into the buildings that needs to be treated, the water treatment facility will be taxed with excess load, which may cause a problem.
  • It is difficult to stop the inflow of groundwater completely, and TEPCO is not planning any countermeasure construction. Regarding the continued inflow of groundwater into the buildings, TEPCO's Junichi Matsumoto says, "We have to come up with a more compact water treatment system in which we can circulate water without using the basements of the buildings. Otherwise we would be stuck in a situation where we have to treat the groundwater coming into the basements." However, there is no prospect of fundamentally solving the problem.And there will be no such prospect, as TEPCO is now proven to be very good at looking the other way. Over 10 sieverts/hour ultra-hot spot? Not a problem, we will just cordon off the area. What is causing 10 sieverts/hour radiation? Why it's not our problem. How much over 10 sieverts/hour? We don't know because we don't measure such things. High hydrogen concentration in the pipe? Not a problem, we will just blow nitrogen gas. What is causing the high hydrogen concentration? It's not our problem. A worker died after 1 week of work at the plant. Why? It's not our problem, it's the subcontractor's problem...

atomic power review: Fukushima Daiichi update: October 28, 2011[28Oct11] - 0 views

  • TEPCO has announced that as of today, the final additions to the enclosure structure at No. 1 reactor building have been made (air circulation and filtration equipment) and that the inspection of the structure and systems by NISA is completed satisfactorily. The structure itself has been completed for a while, but this might be considered as the official commissioning of the entire structure and ventilation system.-TEPCO has also announced that it will drastically increase the amount of water being injected to No. 1 reactor in order to cut down on evaporation inside the structure. It appears that the high humidity environment is hampering the ability to work inside, so TEPCO will increase the feed rate through the feed line (normal feedwater injection line) upward from 4 cubic meters per hour to 7.5 cubic meters per hour over four days. When the conditions of the plant are ascertained at that point TEPCO will further increase water flow. This will also reduce drastically any gaseous emissions to the enclosure from the damaged reactor.
  • TEPCO has discovered a nearly or else completely sheared axle shaft casing on the overhead crane at the common spent fuel building at Fukushima Daiichi. The cause is yet unknown, and no hazard is posed at this time. -TEPCO is almost ready to place the gas handling system (improvised arrangement) at No. 2 reactor plant (to handle gases in the primary containment) into operation. This system will filter out radioactive airborne contaminants. Similar systems will be employed eventually at all three reactors.
  • Finally, airborne releases from Fukushima Daiichi continue to decline .. contrary to many reports on anti-nuclear sites .. as shown by these two panels from a report issued by the Japanese Prime Minister's office.
  • ...1 more annotation...
  • Surely the increased water injection reflects the desire to avoid turning the inside of the enclosure into a radioactive steam bath.However, afaik, the residual heat of the reactor 1 core is now down to about a megawatt. Assuming 1 calorie equals roughly 4 watt seconds, that is about 900 million calories/hr, dumped into 8 tons, about 8 million grams, of cooling water, well over 100 calories/gram. So the 8 tons/hr water injection appears insufficient to absorb the heat load without boiling. Presumably TEPCO estimates the residual heat to be less than 1 megawatt, but it still seems a marginal cooling flow rate. The continued poor performance of the water processing system, running at around 40% in the latest JAIF summary, may be constraining TEPCOs ability to cool more aggressively.

NISA Says Stress Tests to RestartJapanese Reactors Will Take Months [26Jul11] - 0 views

  • Plant Status After a 6.2 magnitude earthquake struck offshore from Fukushima in the early hours of July 25, Tokyo Electric Power Co. reported there were no problems with any of the systems used to stabilize the reactors at Fukushima Daiichi and no injuries. TEPCO checked the systems for water and nitrogen injection into reactors 1, 2 and 3, the water treatment facility, and the used fuel pool cooling systems for reactors 2 and 3. The Japan Atomic Industry Forum said temperatures at the bottom of Fukushima Daiichi reactor 1 have remained below 100 degrees Celsius (212 Fahrenheit) for six consecutive days through July 24. TEPCO says it achieved the lowered temperature by raising the amount of water injected into the reactor. The company has begun implementing step 2 of its recovery plan for the reactors, which includes maintaining temperatures at the bottom of reactors 1, 2 and 3 below 100 degrees Celsius. The stable operation of the circulatory water injection system is crucial to achieving that goal. TEPCO said a faulty circuit breaker was the cause of a five-hour loss of electrical power to reactors 3 and 4 July 22. Power for contaminated water treatment and for the reactors’ used fuel pool cooling was eventually restored via an alternate source. TEPCO says there was no major increase in the temperature of the pools
  • The company is working to improve switching systems among external power supplies. Industry/Regulatory/Political Issues A July 28 public Nuclear Regulatory Commission meeting will focus on the agency’s near-term task force recommendations for safety enhancements at U.S. nuclear energy facilities after the Fukushima accident. International Atomic Energy Agency Director General Yukiya Amano today toured the Fukushima Daiichi site, where he met with TEPCO personnel and gave an interview on location describing his visit. Amano is to meet Japanese Prime Minister Naoto Kan and government ministers to discuss the outcomes of the June IAEA ministerial conference on nuclear safety. The Nuclear and Industrial Safety Agency said it will take months to complete the first of two-stage “stress tests” it has ordered all Japanese nuclear power reactor operators to conduct before shutdown reactors can restart. NISA said it does not anticipate any of the 22 reactors that were halted for regular safety checks to resume operations this summer. The tests involve computer simulations of the reactors’ responses to emergencies such as earthquakes, tsunamis and loss of off-site power.
  • As TEPCO moves into the second stage of its recovery plan at Fukushima, the joint office it operates with the Japanese government to conduct and review its activities will be restructured. A new radiation and health management team will be established, and two other teams will be incorporated into a “medium-to-long term countermeasures” team. Media Highlights The New York Times editorialized on July 24 on the U.S. response to the Fukushima Daiichi accident.

#Fukushima I Nuke Plant: Water Treatment System Is in Trouble [15Jul11] - 0 views

  • Something is going wrong. TEPCO has started to use fresh water taken from the river to cool the reactors, because the treated water that it has been using is running low.From Yomiuri Shinbun (10:23PM JST 7/15/2011):
  • TEPCO announced on July 15 that the company started to use the fresh water from outside source to supplement the treated water it has been using to cool the reactors for two weeks. The contaminated water treatment system at Fukushima I Nuclear Power Plant is not functioning well.
  • If the outside water is used, that will increase the amount of contaminated water. TEPCO is trying to identify the cause of the problem.
  • ...3 more annotations...
  • The system can process 50 tonnes of water per hour. During the one week that ended on July 12, however, the rate was 37 tonnes per hour. TEPCO stopped the system at 5:14AM on July 15 to expel the air out of the pipes and restarted the system at 2:21PM, but the operating rate still remains at 39 tonnes per hour.
  • As the result, the amount of treated water in the storage tank has dropped to 35% of the full capacity, so TEPCO replenished the tank with 570 tonnes of river water to bring it to 63% capacity. If outside water is added, the contaminated water will increase.
  • Let's see..63 minus 35 equals 28.570 tonnes equal 28% of the capacity.So the tank holds 2,035 tonnes.Hmmm, the number doesn't match up with the information on TEPCO's drawing, which shows the storage tank to have the capacity of 5,000 tonnes and the buffer tank that can mix river water with contaminated water if needed has only 1,000 tonnes capacity. There is no tank with 2,000 tonnes capacity in the drawing...

#Fukushima I Nuke Plant: Hydrogen Gas Level Increased in Reactor 2 [29Oct11] - 0 views

  • TEPCO announced on October 30 that the hydrogen concentration in the gas being sucked out from inside the Containment Vessel of Reactor 2 at Fukushima I Nuclear Power Plant rose to 2.7%. Nitrogen gas is continuously pumped to eliminate oxygen gas, and the company says "It is not the level where we need to worry about explosion."
  • The gas management system started to operate on October 28 in Reactor 2. The system sucks the gas out of the Containment system, run it through filters and release it outside [the building]. When the system started running, the hydrogen concentration was about 1%. However, at 5PM on October 30, the concentration rose to 2.7%. TEPCO has increased the amount of nitrogen gas [into the Containment Vessel] to prevent the hydrogen concentration from rising further
  • TEPCO's Kawamata says, "The gas [inside the CV] has been disturbed [because of the gas management system] and that is stirring up hydrogen."What a non-answer.The hydrogen concentration level at which a danger of explosion increases is 4%.

Cyber-security of continent's power grid 'chaotic,' report warns [16Nov11] - 0 views

  • The cyber-security of the North American power grid is "in a state of near chaos," according to a report by a respected U.S. energy consultancy monitoring the industry's transition to wireless digital technologies.The white paper by Pike Research reveals that a $60 smart phone application can bypass security measures and allow direct communications between the phone and some control systems (ICS) that regulate breakers, relays, feeders and the flow of electricity.The news comes on the heels of a warning from the cyber-security arm of the U.S. Department of Homeland Security that the hacker collective known as Anonymous appears intent on exploiting the ICS vulnerabilities within the energy industry.
  • In an unclassified October bulletin obtained by the website Public Intelligence, the National Cybersecurity and Communications Integration Center believes the group has, "a limited ability to conduct attacks against ICS. However . . . Anonymous could be able to develop capabilities to trespass on control system networks very quickly."In July, Anonymous threatened to target companies involved with Alberta's oilsands.
  • North America's power supply has never been disrupted by hackers, though there have been numerous uneventful penetrations of the system, including at Ontario utilities.A chill went through the critical infrastructure industry last summer when a malicious computer worm called Stuxnet attacked Iran's uranium enrichment plants.

  • Many ICS have lifespans of 30 years and mitigation and compensation measures to help them mesh with the newer technologies are creating additional weak links and vulnerabilities.
  • Another worrisome change involves tens of millions of wireless "smart meters" being installed in homes and businesses for faster, more efficient two-way communications with local utilities via the Internet. Utilities, in turn, are networked with the big transmission operators and bulk power generators. More than 300,000 smart meters are installed in Ottawa homes and small businesses.The concern is that they potentially expose the system to hackers and other cyber attacks.

US Radiation Monitoring May Have Been Handed Off To Nuclear Industry [04Nov11] Lobbyist... - 0 views

  • Lucas W Hixson may have uncovered a major abuse of the public trust by the NRC. In late March 2011 the NRC issued a directive that allowed the nuclear industry lobbyist group NEI to supply radiation monitoring data to the NRC who would then forward it to the EPA. March 24th the NRC discussed handing over radiation monitoring to nuclear industry lobbyists, April 14th RadNet was shut down and went back to routine monitoring schedules. This meant no ongoing food,water and air filter testing. Only the radiation level monitors were left operating. The EPA claimed that levels were going down as the reason for shutting down the expanded monitoring, but places like Idaho did not have the decreases seen at other sites.
  • The NRC directive put commercial nuclear power plant owners in charge of voluntarily providing the public with radiation monitoring data but it would be run through their nuclear industry lobbyists before it would then be provided to the NRC. Raw data was not provided directly to the NRC. Considering the massive US nuclear industry offensive to flood the media with propaganda downplaying the Fukushima nuclear disaster, they are hardly a reliable source to tell the public what the radiation levels are.
  • RadNet itself had many problems, stations didn’t work, some were not calibrated before the disaster. Even more disturbing is that the EPA does not even handle their own radiation monitoring network. The important function falls to a former Bush administration appointee running a business out of a rundown storefront in New Mexico. Under a $238,000 no bid contract Environmental Dimensions supposedly manages, maintains and operates RadNet, the only tool the public has to see if we are being subjected to nuclear fallout. The blogger that broke this story states that Environmental Dimensions has tripled their revenue in recent years. The company cites a different address as their mailing address. This shows up as a tiny house in Albuquerque. EDI was also part of a 12 million dollar contract in 2010 along with a couple of other contractors. The contract provides environmental & remediation services to the US Corps of Engineers. EDI claims to have been in business since 1990 but owner, Ms. Bradshaw worked for the DoD in 2006.

  • What little system the public has for radiation notification through the EPA has been shuffled off to a no bid contract with spurious origins and the system experienced widespread problems when it was needed most. That system was mostly turned off just over a month after the disaster. The NRC, the agency tasked with protecting the public from nuclear disasters decided to hand everything over to the nuclear industry’s lobbyists.

L-3 MAPPS Attains Major Milestone on Ling Ao Phase II Simulator Project [20Jul11] - 0 views

  • L-3 MAPPS announced today that the Ling Ao Phase II nuclear power plant full scope simulator (FSS), the first-ever simulator for a CPR1000 plant, has attained another significant milestone. In a ceremony held in Paris on 28 June 2011 marking the issuance of the provisional acceptance certificate (PAC), L-3 MAPPS joined AREVA, Siemens, Daya Bay Nuclear Power Operations and Management Company (DNMC) and China Nuclear Power Engineering Company (CNPEC) to formally hand over the simulator to DNMC on behalf of the Ling Dong Nuclear Power Company
  • In cooperation with AREVA and Siemens, L-3 MAPPS successfully delivered and installed the FSS in August 2009. The first plant license operator examinations were successfully carried out on the FSS and witnessed in January 2010 by China's nuclear regulatory authority, the National Nuclear Safety Administration. Unit 1 of the Ling Ao Phase II complex entered commercial operation in September 2010 and Unit 2 is planned for August 2011
  • To achieve PAC, the simulator was updated to account for all plant changes since the August 2009 simulator delivery, including commercial operation results. A simulator availability test was performed, which demonstrated a simulator availability of 99.42 percent. With this milestone achieved, the simulator’s warranty period is now underway.

  • “With the plant and digital control systems (DCS) designs being firmed up in parallel with the simulator’s development, the supplier and customer teams faced tremendous hurdles to complete this project,” said Peter Dawson, president of L-3 MAPPS. “We are extremely proud of what the team has accomplished on the Ling Ao Phase II program and are grateful to so many contributors, including representatives from DNMC, CNPEC, AREVA and Siemens for their outstanding collaboration.” 
  • Integrated with AREVA- and Siemens-supplied DCSs, replica control room panels, and a stimulated human-machine interface, the FSS features L-3 MAPPS’ advanced instructor station capabilities and a proven Windows-based graphical simulation environment. Advanced plant models have been deployed and validated for the reactor, thermal-hydraulic, balance of plant, electrical, and I&C for the turbine control and other miscellaneous systems not controlled by the AREVA/Siemens DCSs. The safety systems DCS is AREVA’s Teleperm XS, and the operational I&C DCS system is Siemens’ SPPA-T2000 with OM690 human-machine interface.

How safe is India's nuclear energy programme? [23Aug11] - 0 views

  • The March nuclear disaster in Fukushima in Japan led countries with nuclear power plants to revisit safety measures. The International Atomic Energy Agency constituted a global expert fact-finding mission to the island nation. The purpose of the mission was to ascertain facts and identify initial lessons to be learned for sharing with the nuclear community.
  • The mission submitted its report in June and the report stated in clear terms that “there were insufficient defence for tsunami hazards. Tsunami hazards that were considered in 2002 were underestimated. Additional protective measures were not reviewed and approved by the regulatory authority. Severe accident management provisions were not adequate to cope with multiple plant failures”.
  • Further, on the regulatory environment the report states: “Japan has a well organized emergency preparedness and response system as demonstrated by the handling of the Fukushima accident. Nevertheless, complicated structures and organizations can result in delays in urgent decision making.” The inability to foresee such extreme scenarios is a forewarning to countries that are expanding nuclear capacity at a frenzied pace.
  • ...13 more annotations...
  • For India, this is a lesson and an exceptional opportunity to relook at the protected structures of the department of atomic energy (DAE), and establish more transparent processes and procedures.
  • In the past, the Three Mile Island incident (1979) and Chernobyl accident (1986) had provided similar opportunities to evaluate nuclear safety and regulatory systems. India, in response to these incidents, constituted safety audits to assess the safety of nuclear power plants. However, A. Gopalakrishnan, (a former chairman of Atomic Energy Regulatory Board) in his recent article said, “DAE management classified these audit reports as ‘top secret’ and shelved them. No action was taken on the committee’s findings.”
  • If this is so, these reports, or at least action-taken reports, ought to have been published and made available. Such steps could have guaranteed DAE considerable public faith in the functioning of regulatory authorities and given significant confidence in engaging with stakeholders in the present expansion plan.
  • Nuclear Power Corp. of India Ltd, post-Fukushima has undertaken safety evaluation of 20 operating power plants and nuclear power plants under construction. The inm report titled Safety Evaluation of Indian Nuclear Power Plants Post Fukushima Incident suggested a series of safety measures that must be incorporated in all the audited nuclear power plants in a time-bound manner. Measures pertain to strengthening technical and power systems, automatic reactor shutdown on sensing seismic activity, enhancement of tsunami bunds at all coastal stations, etc.
  • However, in the same breath, the report provides assurance by stating that, “adequate provisions exist at Indian nuclear power plants to handle station blackout situations and maintain continuous cooling of reactor cores for decay heat removal”. Further, the reports recalls, “the incidents at Indian nuclear power plants, like prolonged loss of power supplies at Narora plant in 1993, flood incident at Kakrapar plant in 1994 and tsunami at Madras (Chennai) plant in 2004 were managed successfully with existing provisions.”
  • DAE’s official response, post-Fukushima, has been cautious while providing assurance. Separately, DAE has made it clear the nuclear energy programme will continue as planned after incorporating the additional safety features identified by the safety audit report.
  • Prime Minister Manmohan Singh in his speech two days ago in West Bengal was emphatic about the future of India’s nuclear energy programme. He said that “there would be no looking back on nuclear energy. We are in the process of expanding our civil nuclear energy programme. Even as we do so, we have to ensure that the use of nuclear energy meets the highest safety standards. This is a matter on which there can be no compromise”.
  • S. Banerjee, chairman of Atomic Energy Commission and secretary DAE at the International Atomic Energy Agency Ministerial Conference on Safety, categorically said: “India’s effort has been to achieve continuous improvement and innovation in nuclear safety with the basic principle being, safety first, production next.” This is important at a time when we are in the process of expanding nuclear capacity at an incredible pace.
  • Currently, there are several domestic and international power projects in the pipeline. DAE has projected 20,000MWe (megawatt electric) by 2020 from present 4,780MWe, a fourfold increase from the current production. Going further, Banerjee stated that India hopes to achieve targets exceeding 30,000MWe by 2020 and 60,000MWe by 2032. This is a tall order, considering our experience in executing major infrastructure projects. DAE has struggled in the past to achieve targets.
  • Execution of these targets is to be achieved by importing high-capacity reactors and through DAE’s own programme. As we see greater activity in the nuclear energy sector?which was traditionally not transparent in engaging with the public?the trust deficit could only widen as we expand the programme
  • Land acquisition is already a major concern for infrastructure projects and has become an issue at the proposed Jaitapur nuclear power plant as well. However, the biggest challenge in this expansion would be to convince the public of the safety and security of nuclear power plants and also arrive at a comprehensive information and communication package for states in whose territory projects are being executed. Because of the nature of India’s nuclear programme?the combined existence of civilian and military programmes?the nation may not be in a position to achieve the kind of regulatory autonomy, process and engagement that has been witnessed in many European countries and in the US.
  • The bifurcation of India’s nuclear establishment into civilian and military, subsequent to commitment under India-US civil nuclear cooperation has provided with the prospect of an empowered regulatory system.
  • Incidents in Jaitapur and the Fukushima nuclear disaster have further pushed the government to commit to establish an independent nuclear regulator, the Bill of which is expected to be in Parliament any time this year. Nuclear programme is likely to face more complex issues in the future with respect to environment, social and health. Neighbouring countries may also join the chorus soon since some of the proposed nuclear power plant sites are close to our borders

Radioactive waste piles up at Fukushima nuclear plant as disposal method remains in lim... - 0 views

  • Three months after the start of full-scale water circulation system operations at the crippled Fukushima No. 1 Nuclear Power Plant, high-level radioactive waste has kept piling up amid no clear indications of its final disposal destination. As of Sept. 27, plant operator Tokyo Electric Power Co. (TEPCO) had accumulated about 4,700 drums of radioactive waste after three months of cesium decontamination operations initially using U.S. and French equipment which was later joined by Toshiba Corp.’s “Sally” system in August. Since the start of October, TEPCO has conducted the plant’s water circulation operations using the Sally system alone while relegating its U.S. and French counterparts built by Kurion Inc. and Areva SA, respectively, to backups. The Kurion and Sally systems are designed to purify decontaminated water through an absorption unit called a “vessel” that contains zeolites. The vessel is changed every few days and the used vessels become radioactive waste. End Extract

Fukushima Cover Up Unravels [04Jul11] - 0 views

  • Asia Pacific Journal reports:
  • Japan’s leading business journal Toyo Keizai has published an article by Hokkaido Cancer Center director Nishio Masamichi, a radiation treatment specialist.
  • Nishio originally called for “calm” in the days after the accident. Now, he argues, that as the gravity of the situation at the plant has become more clear, the specter of long-term radiation exposure must be reckoned with.
  • ...21 more annotations...
  • And while there have been scattered reports already of food contamination—of tea leaves and spinach, for example—Mr. Kosako said there will be broader, more disturbing discoveries later this year, especially as rice, Japan’s staple, is harvested. “Come the harvest season in the fall, there will be a chaos,” Mr. Kosako said. “Among the rice harvested, there will certainly be some radiation contamination—though I don’t know at what levels—setting off a scandal. If people stop buying rice from Tohoku, . . . we’ll have a tricky problem.”
  • The Atlantic points out:
  • The reason for official reluctance to admit that the earthquake did direct structural damage to reactor one is obvious. Katsunobu Onda, author of TEPCO: The Dark Empire … who sounded the alarm about the firm in his 2007 book explains it this way: “If TEPCO and the government of Japan admit an earthquake can do direct damage to the reactor, this raises suspicions about the safety of every reactor they run. They are using a number of antiquated reactors that have the same systematic problems, the same wear and tear on the piping.”
  • Oddly enough, while TEPCO later insisted that the cause of the meltdown was the tsunami knocking out emergency power systems, at the 7:47 p.m. TEPCO press conference the same day, the spokesman in response to questions from the press about the cooling systems stated that the emergency water circulation equipment and reactor core isolation time cooling systems would work even without electricity
  • On May 15, TEPCO went some way toward admitting at least some of these claims in a report called “Reactor Core Status of Fukushima Daiichi Nuclear Power Station Unit One.” The report said there might have been pre-tsunami damage to key facilities including pipes. “This means that assurances from the industry in Japan and overseas that the reactors were robust is now blown apart,” said Shaun Burnie, an independent nuclear waste consultant. “It raises fundamental questions on all reactors in high seismic risk areas.”
  • Eyewitness testimony and TEPCO’S own data indicates that the damage [done to the plant by the quake] was significant. All of this despite the fact that shaking experienced at the plant during the quake was within it’s approved design specifications
  • The Wall Street Journal writes:
  • A former nuclear adviser to Japanese Prime Minister Naoto Kan blasted the government’s continuing handling of the crisis, and predicted further revelations of radiation threats to the public in the coming months. In his first media interview since resigning his post in protest in April, Toshiso Kosako, one of the country’s leading experts on radiation safety, said Mr. Kan’s government has been slow to test for possible dangers in the sea and to fish and has understated certain radiation dangers to minimize what it will have to spend to clean up contamination.
  • Former Minister for Internal Affairs Haraguchi Kazuhiro has alleged that radiation monitoring station data was actually three decimal places greater than the numbers released to the public. If this is true, it constitutes a “national crime”, in Nishio’s words
  • And – as the Guardian notes in a third article – the collusion between the British government and nuclear companies is leading to political fallout:
  • It’s not just the Japanese. As the Guardian notes:
  • The Guardian reports in a second article
  • British government officials approached nuclear companies to draw up a co-ordinated public relations strategy to play down the Fukushima nuclear accident just two days after the earthquake and tsunami in Japan and before the extent of the radiation leak was known. Internal emails seen by the Guardian show how the business and energy departments worked closely behind the scenes with the multinational companies EDF Energy, Areva and Westinghouse… Officials stressed the importance of preventing the incident from undermining public support for nuclear power.
  • The Conservative MP Zac Goldsmith, who sits on the Commons environmental audit committee, condemned the extent of co-ordination between the government and nuclear companies that the emails appear to reveal.
  • The official suggested that if companies sent in their comments, they could be incorporated into briefs to ministers and government statements. “We need to all be working from the same material to get the message through to the media and the public
  • The office for nuclear development invited companies to attend a meeting at the NIA’s headquarters in London. The aim was “to discuss a joint communications and engagement strategy aimed at ensuring we maintain confidence among the British public on the safety of nuclear power stations and nuclear new-build policy in light of recent events at the Fukushima nuclear power plant”. Other documents released by the government’s safety watchdog, the office for nuclear regulation, reveal that the text of an announcement on 5 April about the impact of Fukushima on the new nuclear programme was privately cleared with nuclear industry representatives at a meeting the previous week. According to one former regulator, who preferred not to be named, the degree of collusion was “truly shocking”.
  • The release of 80 emails showing that in the days after the Fukushima accident not one but two government departments were working with nuclear companies to spin one of the biggest industrial catastrophes of the last 50 years, even as people were dying and a vast area was being made uninhabitable, is shocking
  • What the emails shows is a weak government, captured by a powerful industry colluding to at least misinform and very probably lie to the public and the media.
  • To argue that the radiation was being released deliberately and was “all part of the safety systems to control and manage a situation” is Orwellian.
  • British Shenanigans
  • “This deliberate and (sadly) very effective attempt to ‘calm’ the reporting of the true story of Fukushima is a terrible betrayal of liberal values. In my view it is not acceptable that a Liberal Democrat cabinet minister presides over a department deeply involved in a blatant conspiracy designed to manipulate the truth in order to protect corporate interests”. -Andy Myles, Liberal Democrat party’s former chief executive in Scotland “These emails corroborate my own impression that there has been a strange silence in the UK following the Fukushima disaster … in the UK, new nuclear sites have been announced before the results of the Europe-wide review of nuclear safety has been completed. Today’s news strengthens the case for the government to halt new nuclear plans until an independent and transparent review has been conducted.” -Fiona Hall, leader of the Liberal Democrats in the European parliament

'Mediterranean electrical super Grid Possible [29Oct11] - 0 views

  • There is a real possibility of creating a circuitous electrical super-grid, that begins in Spain, heads eastward through northern Africa and back toward Europe through the eastern Mediterranean nations via Turkey, in the foreseeable future, according to experts who discussed the vision at a conference in Tel Aviv on Thursday.The conference, hosted by Israel’s branch of CIGRE: International Council on Large Electric Systems, featured lead researchers and innovators from all over the world to speak about different techniques of transmitting power within, and among, their countries.
  • Establishing an interconnected grid throughout the Mediterranean basin is the work of a Paris-based organization called Medgrid, which is pushing for the continuation of a project called MEDRING, started quite some time ago, which would successfully link the countries electrically, thereby reducing individual infrastructural demands and boosting all of these nation’s economies.Members of the private joint venture currently include 20 European Union and southeast Mediterranean companies, among which include Egypt, Jordan, Morocco and Syria – but not yet Israel due to its electrical isolation.
  • “The objective of Medgrid is to design the Mediterranean interconnection grid with a time target that is about 2020-2025, which is a bit near, in comparison with DESERTEC, which is 2050,” said Jean Kowal, executive vice president of Medgrid and former secretary general of CIGRE-France, referring to a campaign that aims to harness large amounts of desert light on a high voltage supergrid by 2050. Creating the Medgrid would complement European Union objectives for 2020, which include a 20 percent reduction in carbon dioxide compared to 1990 levels, a 20% gain in energy efficiency, and ensuring that 20% of energy consumption comes from renewable, according to Kowal.

  • Meanwhile, also in line with the planned grid would be a program called the Mediterranean Solar Plan, which is pushing for the quicker development of renewable energy sources in the southern and eastern rims of the Mediterranean, mostly through solar power, Kowal added. “This solar plan cannot become a reality if you don’t have a transmission system to transmit the electricity,” he said. Medgrid would serve as such a transmission system, to allow neighbor nations to benefit from each other’s renewable sources, rather than relying on polluting sources to fill in gaps during peak hours, according to Kowal.
  • The idea is to try to find out what could be this network all around the Mediterranean, but also to assess what could be the conditions to make it real because there are so many problems,” he added. One such problem, according to Kowal, is that the interconnections between the southeastern Mediterranean countries are currently very weak, particularly among Tunisia, Libya and Egypt. “If we want to develop this system, we will have to rely on submarine cables going from south to north,” he said, noting, however, that cables can currently only go to a maximum depth of 1,650 meters.
