BELLONA.ORG: Norway pulls plug on electricity from Kola Nuclear Power Plant's ageing re... - 0 views

  • Norway has given the cold shoulder to plans to buy energy from the Murmansk region to power gas recovery operations at the northerly Melkøya field until the two oldest reactors at the Kola Nuclear Power Plant (NPP) are taken out of service in 2018 or 2019. Anna Kireeva, Charles Digges, 13/08-2012 Norway’s Ministry of Petroleum and Energy sent an official letter to Norwegian grid operator Statnett in which it said that planned imports of electricity via links between Norwegian and Russian energy networks were not to proceed until Kola NPPs reactor Nos 1 and 2 are taken offline.

Measures radioactive iodine in Barents Region [30Jan12] - 0 views

  • Very low levels of the radioactive isotope iodine-131 in northern part of Norway, Sweden and Finland. Norwegian Radiation authorities is unsure about the source, but says it might come from, or via Russian territory.
  • Norwegian Radiation Protection Authorities (NRPA) says in a short press-note Tuesday evening that the levels they measured pose no health risk. The measurements of radioactive iodine in northern part of the Barents Region were made several days ago, but results of the analyses were first made public Tuesday evening by coordinated press-notes from radiation authorities in Finland, Sweden and Norway. NRPA says that two of the six online measuring stations in Finnmark in the high north of Norway have indicated increased levels of radioactive iodine.
  • Swedish radiation protection authority says in thier brief that very low levels of radioactive iodine-131 are meassured at their station in Kiruna in northern Sweden.

  • Neither Swedish, Finnish nor Norwegian authorities have been  informed about any releases of radioactivity anyplace in northern Europe.  The source is most likely a reactor or a isotope-source at a hospital, according to the press-note from NRPA.

Chain reaction scare at Fukushima only fission incident, say authorities, but environme... - 0 views

  • A scare last week in which technicians and observers warned of a possible chain reaction in Fukushima Daiichi’s destroyed reactor No. 2 has now been determined to be a “spontaneous fission incident” – a process of radioactive decay that does not involve a chain reaction.
  • The fears behind a possible chain reaction centered on the discovery of xenon gas as a possible harbinger of further fuel melts at the reactors – three of which experienced full meltdowns after the plant was hit by a 9.0 magnitude earthquake and tsunami in March. But both the plant’s owner, Tokyo Electric Power Co (TEPCO) and nuclear physicist Katsutada Aoki have said that the presence of xenon is not an indication that the wrecked fuel in the reactors has re-achieved “criticality” - or a sustained chain reaction of nuclear fission.  "The discovery of xenon in the reactor is no reason to fear anything serious," Aoki, an expert in nuclear engineering who headed the reactor physics division of the Atomic Energy Society of Japan, told the Japan Times.
  • TEPCO said this week that it considered the source of the xenon to be spontaneous fission because technicians had injected boric acid into the reactor vessel to reduce the likelihood of chain fission reactions but was still able to detect xenon. Temperature and pressure data from the unit also showed no change around the time of the xenon's discovery in another indication that chain reactions were not taking place. TEPCO slammed for spreading fear But Aoki criticized TEPCO, saying the utility could have done a better job analyzing the implications of the newly discovered xenon gases and avoided spreading needless fear that a nuclear chain reaction might have restarted. In a confusing and worrying announcement, TEPCO revealed last Wednesday that it found one one-hundred-thousandth of a becquerel per 1 cubic centimeter of xenon-133 and xenon-135 in gas samples from reactor No. 2, saying it might indicate the melted fuel in the reactor could have briefly reached criticality since xenon can be generated through such nuclear fission.

  • But one day after the announcement, TEPCO denied criticality had occurred, saying it found the amount of xenon was too small to be generated through fission via criticality. Chances of chain reaction not zero Spontaneous fission should not be confused with nuclear criticality, said Aoki, especially since both the temperature and the pressure levels have remained stable in the reactor. But he did say that “the chances of criticality taking place is not zero.” This is what concerns some environmentalists who have closely been observing developments of the ongoing crisis at Fukushima Daiichi, especially given the sheer quantity of melted fuel at the plant.
  • “I don't think there is a reason to say situation [with a possible chain reaction] has improved much actually,” wrote Vladimir Slivyak, co-chair of Russia’s Ecodefence in an email interview.  “We see the possibility of chain reaction is still there and no one can actually guarantee that no problems will again occur at Fukushima.” An uncontrolled chain reaction occurring in the bowels of one of Fukushima Daiichi’s wrecked reactors could lead to an explosion and yet further spread of radioactivity. One independent report released in Norway this month indicated that releases of radioactive caesium-137 from Fukushima Daiichi equal 40 percent of that which was released at Chernobyl in 1986. Another report by the French Institute for Radiological Protection and Nuclear Safety also stated that the amount of caesium-137 that flowed into the Pacific from the coastal plant is some 30 times more than was estimated by TEPCO.

Proof Of Fukushima Weapons Program Rests On A Pile Of Manure[09Sep11] - 0 views

  • Soon after Japan's triple disaster, I suggested that an official cover-up of a nuclear-weapons program hidden inside the Fukushima No.1 plant was delaying the effort to contain the reactor meltdowns. Soon after the tsunami struck, the Tokyo Electric Power Company reported that only three reactors had been generating electricity on the afternoon of March 11.. (According to the initial report, these were the older GE-built reactors 1,2 and 6.). Yet overheating at five of the plant's six reactors indicated that two additional reactors had also been operating (the newer and more advanced Nos. 3 and 4, built by Toshiba and Hitachi). The only plausible purpose of such unscheduled operation is uranium enrichment toward the production of nuclear warhead
  • On my subsequent sojourns in Japan, other suspicious activities also pointed to a high-level cover-up, including systematic undercounts of radiation levels, inexplicable damage to thousands of imported dosimeters, armed anti-terrorism police aboard trains and inside the dead zone, the jamming of international phone calls, homing devices installed in the GPS of rented cars, and warning visits to contacts by government agents discouraging cooperation with independent investigations. These aggressive infringements on civil liberties cannot be shrugged off as an overreaction to a civil disaster but must have been invoked on grounds of national security.
  • One telltale sign of high-level interference was the refusal by science equipment manufacturers to sell isotope chromatography devices to non-governmental customers, even to organizations ready to pay $170,000 in cash for a single unit. These sensitive instruments can detect the presence of specific isotopes, for example cesium-137 and strontium-90. Whether uranium was being enriched at Fukushima could be determined by the ratio of isotopes from enriched weapons-grade fissile material versus residues from less concentrated fuel rods.

  • Now six months after the disaster, the smoking gun has finally surfaced, not on a Japanese paddy field but inside a pile of steer manure from a pasture near Sacramento, California
  • The sample of cattle dung and underlying soil was sent to the nuclear engineering lab of the University of California, Berkeley, which reported on September 6:
  • We tested a topsoil sample and a dried manure sample from the Sacramento area. The manure was produced by a cow long before Fukushima and left outside to dry; it was rained on back in March and April. Both samples showed detectable levels of Cs-134 and Cs-137, with the manure showing higher levels than the soil probably because of its different chemical properties and/or lower density. One interesting feature of t the Sacramento and Sonoma soil samples is that the ratio of Cesium-137 to Cesium-134 is very large - approximately 17.6 and 5.5, respectively. All of our other soil samples until now had shown ratios of between 1 and 2. We know from our air and rainwater measurements that material from Fukushima has a cesium ratio in the range of approximately 1.0 to 1.5, meaning that there is extra Cs-137 in these two soil samples. The best explanation is that in addition to Fukushima fallout, we have also detected atmospheric nuclear weapons testing fallout in these soils. Weapons fallout contains only Cs-137 (no Cs-134) and is known to be present in older soils ..Both of these samples come from older soils, while our samples until this point had come from newer soils.
  • The last atmospheric nuclear blast at the Nevada Test Site occurred in 1962, whereas the manure was presumably dropped less than 49 years ago. Over the past year, the approximate life-span of a cow patty, the rain that fell on the plain came not from a former province of Spain. Within that short time-frame, the only possible origin of radioactive fallout was Fukushima.To think otherwise would be lame.
  • Sun-dried manure is more absorbent than the rocky ground of Northern California, which explains the higher level in Sacramento dung than in the Sonoma soil. As a rule of thumb, the accuracy of radiation readings tends to improve with higher concentration of the test material.The manure acted like a sponge for the collection of radioactive rainfall. Its ratio of Cs-137 (resulting from enriched uranium) to Cs-134 (from a civilian fuel rod) is more than 17-to-1. Larger by 1,700 percent, this figure indicates fission of large amounts of weapons-grade material at Fukushima.
  • The recent higher readings were probably based on either late releases from a fire-destroyed extraction facility or the venting of reactor No.3, a Toshiba-designed unit that used plutonium and uranium mixed oxide or MOX fuel. Unannounced nighttime airborne releases in early May caused radiation burns in many people, as happened to my forearms. Those plumes then drifted toward North America.
  • Enrichment of uranium for nuclear warheads is prohibited under constitutional law in Japan and by terms of the Non-Proliferation Treaty. Since no suspects have been charged by prosecutors, this cannot be a plot by a few individuals but stands as the crime of a national entity.
  • Yellow-Cake Factory 608   Fukushima Province has a history of involvement in atomic weapons development, according to a New York Times article by Martin Fackler titled "Fukushima's Long Link to a Dark Nuclear Past" (Sept. 6). Following the lead of Japanese news reports, the correspondent visited the town of Ishikawa, less than an hour's drive south of the Fukushima No.1 nuclear plant. There he interviewed Kiwamu Ariga who as a student during the war was forced to mine uranium ore from a local foothill to supply the military-run Factory 608, which refined the ore into yellow-cake.
  • Several research groups worked on building a super-weapon for militarist Japan. The Naval Technology Research Institute was best-positioned due to its secret cooperation with the German Navy. Submarine U-234 was captured in the Atlantic after Germany's surrender with a cargo of uranium along with two dead passengers - Japanese military officers .Soon after departing Norway, U-864 was bombed and sunk, carrying a load of two tons of processed uranium..
  • In the article for the Atlanta Constitution, dated, Oct. 2, 1946, David Snell reported that the Japanese military had successfully tested a nuclear weapon off Konan on Aug. 12, 1945. There are detractors who dispute the account by a decommissioned Japanese intelligence officer to the American journalist, stationed in occupied Korea with the 24th Criminal Investigation Detachment of the U.S. Army. A cursory check on his background shows Snell to have been a credible reporter for Life magazine, who also contributed to the Smithsonian and The New Yorker magazines. A new book is being written by American and Russian co-authors on the Soviet shoot-down of the Hog Wild, a B-29 that flew over Konan island soon after the war's end..
  • Due to its endemic paranoia about all things nuclear, the U.S. government had a strong interest in suppressing the story of Japan's atomic bomb program during the war, just as Washington now maintains the tightest secrecy over the actual situation at Fukushima.
  • The emerging picture shows that nuclear-weapons development, initiated in 1954 by Prime Minister Nobusuke Kishi and supervised by Yasuhiro Nakasone, was centered inside civilian nuclear plants, since the Self-Defense Forces were bound by strict Constitutional rules against war-making and the Defense Agency is practically under the direct supervision of the U.S. Joint Chiefs of Staff. Funding came from the near-limitless budget of the Tokyo Electric Power Company (TEPCO), which today claims financial insolvency without explanation of how its vast cash holdings disappeared. A clandestine nuclear program must be expensive, since it would include the cost of buying the silence of parliament, the bureaucracy and foreign dignitaries.
  • Following the March 11 disaster, TEPCO sent a team of 250 emergency personnel into the plant, yet only 50 men were assigned to cooling the reactors. The other 200 personnel stayed out of sight, possibly to dismantle an underground plutonium-extraction facility. No foreign nuclear engineers or Japanese journalists were ever permitted entry into the reactor structures.   Radiation leakage from Fukushima No.1 prevented local police from rescuing hundreds of tsunami survivors in South Soma, many of whom consequently went unaided and died of wounds or exposure. Tens of thousands of farmers have lost their ancestral lands, while much of Japan's agriculture and natural areas are contaminated for several generations and possibly longer, for the remaining duration of the human species wherever uranium and plutonium particles have seeped into the aquifers.
  • TEPCO executives, state bureaucrats and physicists in charge of the secret nuclear program are evading justice in contempt of the Constitution. As in World War II, the Japanese conservatives in their maniacal campaign to eliminate their imagined enemies succeeded only in perpetrating crimes against humanity and annihilating their own nation. If history does repeat itself, Tokyo once again needs a tribunal to send another generation of Class-A criminals to the gallows.

Simulation Map of Cesium-137 Deposition Across the Pacific by CEREA Shows Contamination... - 0 views

  • France's CEREA has the simulation map of ground deposition of cesium-137 from the Fukushima I Nuclear Power Plant accident on its "Fukushima" page. It not only shows Japan but also the entire northern Pacific Rim, from Russian Siberia to Alaska to the West Coast of the US to the entire US. According to the map, the US, particularly the West Coast and particularly California, may be more contaminated with radioactive cesium than the western half of Japan or Hokkaido. It looks more contaminated than South Korea or China. Canada doesn't look too well either, particularly along the border with US on the western half.
  • From CEREA's Fukushima page: Atmospheric dispersion of radionuclides from the Fukushima-Daichii nuclear power plant CEREA, joint laboratory École des Ponts ParisTech and EdF R&D Victor Winiarek, Marc Bocquet, Yelva Roustan, Camille Birman, Pierre Tran Map of ground deposition of caesium-137 for the Fukushima-Daichii accident. The simulation was performed with a specific version of the numerical atmospheric chemistry and transport model Polyphemus/Polair3D. The parametrisations used for the transport and physical removal of the radionuclides are described in [1,2,3,4]. The magnitude of the deposition field is uncertain and the simulated values of deposited radionuclides could be significantly different from the actual deposition. In particular, the source term remains uncertain. Therefore, these results should be seen as preliminary and they are likely to be revised as new information become available to better constrain the source term and when radionuclides data can be used to evaluate the model simulation results.
  • The page also has the animated simulation of cesium-137 dispersion from March 11 to April 6, 2011. If the Japanese think they are the only ones who have the radiation and radioactive fallout from the accident, they are very much mistaken, if the simulation is accurate. (Meteorological institutes and bureaus in Austria, Germany, and Norway all had similar simulation maps.) Radioactive materials spewed out of Fukushima I Nuke Plant went up and away on the jet stream, reaching the other side of the Pacific. When the fallout from explosions (March 14, 15) reached the US West Coast, it came with an unusually heavy rainfall in California.

GE Dumps Offshore Wind-Power Plans AFTER Collecting $125 Million In Stimulus ... - 0 views

  • GE was awarded 44 contracts totaling over $46,000,000 and 44 grants totaling more than$79,000,000 from the Obama-Pelosi $757 billion dollar stimulus package. Millions of dollars in stimulus funds were used by GE in green energy projects. Today GE announced that it was going to gut its offshore wind-power plans. Forbes reported: General Electric, the U.S.-based industrial giant and leading manufacturer of wind-power turbines, is scaling back efforts to expand its presence in the offshore wind power market.
  • The rationale: there is no meaningful offshore wind market to speak of – at least not yet.  Given slower-than-expected industry growth, the offshore market may not mature as rapidly as many wind boosters once believed.  In 2009, GE moved into the offshore market by acquiring Norway’s ScanWind, a developer of direct-drive turbines, based in the city of Trondheim. GE is considering laying off about 40 employees in Norway as it scales-back its offshore operations there, according to reports in Recharge. The company has also suspended plans to construct a manufacturing facility in the United Kingdom indefinitely. Immelt also said the stimulus would work way back in April 2009.

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.
  • 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  
  • 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
  • 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  
  • 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

BP gets Gulf oil drilling permit amid 28,000 unmonitored abandoned wells [25Oct11] - 0 views

  • Since BP’s catastrophic Macondo Blowout in the Gulf of Mexico last year, the Obama Administration has granted nearly 300 new drilling permits [1] and shirked plans to plug 3,600 of more than 28,000 abandoned wells, which pose significant threats to the severely damaged sea. Among those granted new permits for drilling in the Gulf, on Friday Obama granted BP permission to explore for oil in the Gulf, allowing it to bid on new leases that will be sold at auction in December. Reports Dow Jones: “The upcoming lease sale, scheduled for Dec. 14 in New Orleans, involves leases in the western Gulf of Mexico. The leases cover about 21 million acres, in water depths of up to 11,000 feet. It will be the first lease auction since the Deepwater Horizon spill.” [2]
  • Massachusetts Rep. Ed Markey objected to BP’s participation in the upcoming lease sale, pointing out that: “Comprehensive safety legislation hasn’t passed Congress, and BP hasn’t paid the fines they owe for their spill, yet BP is being given back the keys to drill in the Gulf.” Environmental watchdog, Oceana, added its objection to the new permits, saying that none of the new rules implemented since April 2010 would have prevented the BP disaster. “Our analysis shows that while the new rules may increase safety to some degree, they likely would not have prevented the last major oil spill, and similarly do not adequately protect against future ones.” [3]
  • Detailing the failure of the Dept. of Interior’s safety management systems, Oceana summarizes: Regulation exemptions (“departures”) are often granted, including one that arguably led to the BP blowout; Economic incentives make violating rules lucrative because penalties are ridiculously small; Blowout preventers continue to have critical deficiencies; and Oversight and inspection levels are paltry relative to the scale of drilling operation. Nor have any drilling permits been denied [4] since the BP catastrophe on April 20, 2010, which still spews oil today [5].

  • 28,079 Abandoned Wells in Gulf of Mexico In an explosive report at Sky Truth, John Amos reveals from government data that “there are currently 24,486 known permanently abandoned wells in the Gulf of Mexico, and 3,593 ‘temporarily’ abandoned wells, as of October 2011.” [6] TA wells are those temporarily sealed so that future drilling can be re-started. Both TA wells and “permanently abandoned” (PA) wells endure no inspections.
  • Not only cement, but seals, valves and gaskets can deteriorate over time. A 2000 report by C-FER Technologies to the Dept. of Interior identified several  different points where well leaks can occur, as this image (p. 26) reveals.  To date, no regulations prescribe a maximum time wells may remain inactive before being permanently abandoned. [13] “The most common failure mechanisms (corrosion, deterioration, and malfunction) cause mainly small leaks [up to 49 barrels, or 2,058 gallons]. Corrosion is historically known to cause 85% to 90% of small leaks.” Depending on various factors, C-FER concludes that “Shut-In” wells reach an environmental risk threshhold in six months, TA wells in about 10-12 years, and PA wells in 25 years.  Some of these abandoned wells are 63 years old.
  • Leaking abandoned wells pose a significant environmental and economic threat. A three-month EcoHearth investigation revealed that a minimum of 2.5 million abandoned wells in the US and 20-30 million worldwide receive no follow up inspections to ensure they are not leaking. Worse: “There is no known technology for securely sealing these tens of millions of abandoned wells. Many—likely hundreds of thousands—are already hemorrhaging oil, brine and greenhouse gases into the environment. Habitats are being fundamentally altered. Aquifers are being destroyed. Some of these abandoned wells are explosive, capable of building-leveling, toxin-spreading detonations. And thanks to primitive capping technologies, virtually all are leaking now—or will be.” [11] Sealed with cement, adds EcoHearth, “Each abandoned well is an environmental disaster waiting to happen. The triggers include accidents, earthquakes, natural erosion, re-pressurization (either spontaneous or precipitated by fracking) and, simply, time.”
  • As far back as 1994, the Government Accountability Office warned that there was no effective strategy in place to inspect abandoned wells, nor were bonds sufficient to cover the cost of abandonment. Lease abandonment costs estimated at “$4.4 billion in current dollars … were covered by only $68 million in bonds.” [12] The GAO concluded that “leaks can occur… causing serious damage to the environment and marine life,” adding that “MMS has not encouraged the development of nonexplosive structure removal technologies that would eliminate or minimize environmental damage.”
  • Over a year ago, the Dept. of Interior promised to plug the “temporarily abandoned” (TA) wells, and dismantle another 650 production platforms no longer in use. [7] At an estimated decommissioning cost of $1-3 billion [8], none of this work has been started, though Feds have approved 912 permanent abandonment plans and 214 temporary abandonment plans submitted since its September 2010 rule. [9] Over 600 of those abandoned wells belong to BP, reported the Associated Press last year, adding that some of the permanently abandoned wells date back to the 1940s [10].  Amos advises that some of the “temporarily abandoned” wells date back to the 1950s. “Experts say abandoned wells can repressurize, much like a dormant volcano can awaken. And years of exposure to sea water and underground pressure can cause cementing and piping to corrode and weaken,” reports AP.
  • The AP noted that none of the 1994 GAO recommendations have been implemented. Abandoned wells remain uninspected and pose a threat which the government continues to ignore. Agency Reorganization The Minerals Management Service (MMS) was renamed the Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) last May after MMS drew heavy fire for malfeasance, including allowing exemptions to safety rules it granted to BP. An Office of Inspector General investigation revealed that MMS employees accepted gifts from the oil and gas industry, including sex, drugs and trips, and falsified inspection reports. [14] Not only was nothing was done with the 1994 GAO recommendations to protect the environment from abandoned wells, its 2003 reorganization recommendations [15] were likewise ignored.  In a June 2011 report on agency reorganization in the aftermath of the Gulf oil spill, the GAO reports that “as of December 2010,” the DOI “had not implemented many recommendations we made to address numerous weaknesses and challenges.” [16] Reorganization proceeded.  Effective October 1, 2011, the Dept. of the Interior split BOEMRE into three new federal agencies: the Office of Natural Resources Revenue to collect mineral leasing fees, the Bureau of Safety and Environmental Enforcement (BSEE) and the Bureau of Ocean Energy Management (BOEM) “to carry out the offshore energy management and safety and environmental oversight missions.” The DOI admits:
  • “The Deepwater Horizon blowout and resulting oil spill shed light on weaknesses in the federal offshore energy regulatory system, including the overly broad mandate and inherently conflicted missions of MMS which was charged with resource management, safety and environmental protection, and revenue collection.” [17] BOEM essentially manages the development of offshore drilling, while BSEE oversees environmental protection, with some eco-protection overlap between the two agencies. [18] Early this month, BSEE Director Michael R. Bromwich spoke at the Global Offshore Safety Summit Conference in Stavanger, Norway, sponsored by the International Regulators Forum. He announced a new position, Chief Environmental Officer of the BOEM:
  • This person will be empowered, at the national level, to make decisions and final recommendations when leasing and environmental program heads cannot reach agreement. This individual will also be a major participant in setting the scientific agenda for the United States’ oceans.” [19] Bromwich failed to mention anything about the abandoned wells under his purview. Out of sight, out of mind. Cost of the Macondo Blowout
  • On Monday, the GAO published its final report of a three-part series on the Gulf oil disaster. [20]  Focused on federal financial exposure to oil spill claims, the accountants nevertheless point out that, as of May 2011, BP paid $700 million toward those spill claims out of its $20 billion Trust established to cover that deadly accident. BP and Oxford Economics estimate the total cost for eco-cleanup and compensatory economic damages will run to the “tens of billions of dollars.” [21] On the taxpayer side, the GAO estimates the federal government’s costs will exceed the billion dollar incident cap set by the Oil Pollution Act of 1990 (as amended). As of May 2011, agency costs reached past $626 million. The Oil Spill Liability Trust Fund’s income is generated from an oil barrel tax that is set to expire in 2017, notes GAO.
  • With Monday’s District Court decision in Louisiana, BP also faces punitive damages on “thousands of thousands of thousands of claims.” U.S. District Judge Carl Barbier denied BP’s appeal that might have killed several hundred thousand claims, among them that clean up workers have still not been fully paid by BP. [22] Meanwhile, destroying the planet for profit continues unabated. It’s time to Occupy the Gulf of Mexico: No more oil drilling in our food source.

ACPD - Abstract - Xenon-133 and caesium-137 releases into the atmosphere from the Fukus... - 0 views

On 11 March 2011, an earthquake occurred about 130 km off the Pacific coast of Japan's main island Honshu, followed by a large tsunami. The resulting loss of electric power at the Fukushima Dai-ichi nuclear power plant (FD-NPP) developed into a disaster causing massive release of radioactivity into the atmosphere. In this study, we determine the emissions of two isotopes, the noble gas xenon-133 (133Xe) and the aerosol-bound caesium-137 (137Cs), which have very different release characteristics as well as behavior in the atmosphere. To determine radionuclide emissions as a function of height and time until 20 April, we made a first guess of release rates based on fuel inventories and documented accident events at the site.
  • This first guess was subsequently improved by inverse modeling, which combined the first guess with the results of an atmospheric transport model, FLEXPART, and measurement data from several dozen stations in Japan, North America and other regions. We used both atmospheric activity concentration measurements as well as, for 137Cs, measurements of bulk deposition. Regarding 133Xe, we find a total release of 16.7 (uncertainty range 13.4–20.0) EBq, which is the largest radioactive noble gas release in history not associated with nuclear bomb testing. There is strong evidence that the first strong 133Xe release started very early, possibly immediately after the earthquake and the emergency shutdown on 11 March at 06:00 UTC. The entire noble gas inventory of reactor units 1–3 was set free into the atmosphere between 11 and 15 March 2011. For 137Cs, the inversion results give a total emission of 35.8 (23.3–50.1) PBq, or about 42% of the estimated Chernobyl emission. Our results indicate that 137Cs emissions peaked on 14–15 March but were generally high from 12 until 19 March, when they suddenly dropped by orders of magnitude exactly when spraying of water on the spent-fuel pool of unit 4 started. This indicates that emissions were not only coming from the damaged reactor cores, but also from the spent-fuel pool of unit 4 and confirms that the spraying was an effective countermeasure. We also explore the main dispersion and deposition patterns of the radioactive cloud, both regionally for Japan as well as for the entire Northern Hemisphere. While at first sight it seemed fortunate that westerly winds prevailed most of the time during the accident, a different picture emerges from our detailed analysis
  • Exactly during and following the period of the strongest 137Cs emissions on 14 and 15 March as well as after another period with strong emissions on 19 March, the radioactive plume was advected over Eastern Honshu Island, where precipitation deposited a large fraction of 137Cs on land surfaces. The plume was also dispersed quickly over the entire Northern Hemisphere, first reaching North America on 15 March and Europe on 22 March. In general, simulated and observed concentrations of 133Xe and 137Cs both at Japanese as well as at remote sites were in good quantitative agreement with each other. Altogether, we estimate that 6.4 TBq of 137Cs, or 19% of the total fallout until 20 April, were deposited over Japanese land areas, while most of the rest fell over the North Pacific Ocean. Only 0.7 TBq, or 2% of the total fallout were deposited on land areas other than Japan.Discussion Paper (PDF, 6457 KB)   Supplement (13 KB)   Interactive Discussion (Open, 0 Comments)   Manuscript under review for ACP
