UPDATE: Extremely High Radiation (20,000 CPM) in Ontario After Rainfall [16Aug11] - 0 views

  • UPDATE: Nine Mile Point 2 nuclear facility shut down twice in 1 week due to a "higher than normal leak".  On August 8th the plant was shut down, then again on August 11th.  Nine Mile Point 2 is situated on Lake Ontario and was leaking into it.  Could that be the source of the extremely high radiation found in Toronto area rainwater? 9wsyr.com (WSYR-TV) -- The Nine Mile Nuclear Plant's unit two is back up and running. The plant needed to be shut down twice this week because of leaks, but Friday night all the repairs were complete.
  • Inspections have assured that there are no other issues and the unit is back up to about 24 percent power.   It will take a little more time to get the unit back up to 100 percent.   Representatives say the leaks were never a risk to the public, or to plant employees.

U.S. Industry Taking Steps to Learn Lessons from Japan, Enhance Safety at America's Nuc... - 0 views

  • The nuclear energy industry will continue to work with the Nuclear Regulatory Commission as it considers forthcoming recommendations of an agency task force on new procedures and regulations in light of the accident at Fukushima Daiichi.  We have undertaken significant work in the past 90 days to examine our facilities and take the steps necessary to enhance safety.  We will continue to work with the Nuclear Regulatory Commission to understand any potential gaps in safety and fill those gaps. Prompted by the Fukushima accident, the NRC staff has been developing recommendations to enhance safety at America’s reactors. The task force is expected to release its report to the NRC commissioners within the next week. In their interim reports, NRC officials have emphasized that issues identified during the recent inspections will not impede the facilities’ ability to maintain safety even in the face of extreme events.
  • These NRC’s inspections complement industry efforts begun within days of the Fukushima Daiichi accident. Each of the nation’s 104 nuclear energy facilities has been subjected to a comprehensive verification of preparedness to maintain safety during a severe event, regardless of the cause. As a result of these self-inspections, facility operators have made immediate enhancements or developed plans to enhance safety. The vast majority of the items identified by the industry are enhancements to safety measures already in place.
  • The NRC has also made clear that issues identified during its post-Fukushima inspections at each plant do not undermine any facility’s ability to respond to extreme events. This conclusion is based upon exemplary levels of safe operation and the multiple layers of protection that exist at each nuclear energy facility in the country.   Moreover, in its annual reports to Congress, the NRC has listed only one “abnormal occurrence” over the past decade—an incident nine years ago that did not result in the release of radiation. Over the last 10 years, the NRC has not identified any negative trends in safety at America’s nuclear facilities. In the wake of the tragedy in Japan, Americans are concerned about whether U.S. reactors face the same risks.  The fact is, American nuclear facilities are subject to more regulatory scrutiny and requirements than in any other country.  American nuclear energy facilities are equipped and employees are trained to manage severe events. Since the terrorist attacks of Sept. 11, 2001, the industry has made significant improvements in physical structures and emergency response capabilities.

  • Commitment to Continuous Learning, Safety
  • The U.S. industry—through its commitment to continuous learning and relentless pursuit of excellence in safe operations—has taken significant action to ensure that American reactors are operated safety and securely. This includes actions in the following areas: Command and control: key operational and response decisions remain with shift supervisor—Decision-making remains on site with licensed operators. Reactor operators drill on accident scenarios several times each year and are prepared to respond to a wide range of potential severe events.
  • Operator licensing and training—U.S. reactor operators are licensed by the NRC and must re-qualify for their license every two years. U.S. reactor operators spend one week out of six in simulator training, which is more continuous training than pilots and doctors. Safety culture—The industry’s safety culture is transparent and encourages and facilitates the reporting of problems or concerns by employees through several channels. A commitment to safety culture is evidenced by employees who embrace continuous learning and maintain a questioning attitude regarding safety. This attitude gives rise to tools like corrective actions programs.
  • Independent regulator that includes resident inspectors—The NRC is an independent agency whose sole mission is protection of public health and safety. NRC inspectors located at each of America’s nuclear energy facilities have unfettered access to workers and data as part of their daily inspections. Creation of the Institute of Nuclear Power Operations—INPO was formed by the industry after the Three Mile Island accident to drive industry toward operational excellence and above and beyond NRC requirements. Post 9/11 security contingency measures—The NRC and industry took several actions after 9/11 to enhance security at America’s nuclear energy facilities. These features also would help mitigate extreme events, such as large fires or explosions.

Mag: Curium and plutonium outside Fukushima plant indicate nuclear explosion at Reactor... - 0 views

  • Translation of the Dec. 15, 2011 Nature Magazine article by former Prime Minister Yukio Hatoyama and legislator Tomoyuki Taira — both members of  by EX-SKF (Certain expressions may be off, as article was translated English to Japanese and then back to English) [Emphasis Added]: [Subheading:] Possibility of Nuclear Explosion We need to answer the question of what caused the series of explosions at Fukushima I Nuclear Power Plant. Initially, they were reported as hydrogen explosions [...] [T]his is not conclusive. Other possibilities exist, and they are nuclear explosions and gas explosions other than hydrogen gas. [...]
  • From two observed facts, we believe a nuclear explosion is more likely. First, several transuranic elements have been detected several tens of kilometers away from the plant. Second, the steel trusses in the upper part of the reactor building of Reactor 3 are twisted as if they had been melted.
  • According to the reports by the Ministry of Education and Science, curium-242 (242Cm) has been detected at a location 3 kilometers from the plant, and plutonium-238 (238Pu) has been detected at a location 45 kilometers from the plant. [...] 242Cm’s half life is short (about 163 days), and the deposition of 238Pu around the plant is far greater than normal, leading the Ministry of Education and Science to conclude these were emitted from Fukushima I Nuclear Power Plant. If that’s the case, pieces of broken spent nuclear fuel rods may have been scattered around the plant, and it is extremely dangerous.

  • These transuranic elements are not carried by the radioactive plume like much lighter cesium or iodine. Therefore, they must have been blown out by an extremely large force. [...] It is unlikely that a hydrogen explosion generated a high enough temperature that would melt steel
  • TEPCO initially announced that there was a white smoke from Reactor 3 explosion. However, the later investigation has revealed that the smoke was black, and a hydrogen explosion is not considered to generate such a black smoke. Our conclusion therefore is that it [explosion of Reactor 3] may have been a nuclear explosion.

New radiation hotspots prompt Japan to extend monitoring [27Aug11] - 0 views

  • The discovery of radiation hotspots well beyond the exclusion zone around the Fukushima Dai-Ichi nuclear plant has forced the Japanese government to increase its monitoring from six to 22 prefectures in the east of the country.
  • Elevated levels of radiation have been found 125 miles from the power plant, which was destroyed by the March 11 earthquake and tsunami. That is well beyond the 18-mile exclusion zone that has been imposed.Officials in the city of Tokamachi, in northwest Niigata Prefecture, detected 27,000 becquerels of radioactive cesium per kilogramme (2.2lbs) of waste in a school compost heap. By law, any waste containing just 8,000 becquerels per kg must be treated as radioactive waste.
  • Experts and residents say the government should have begun monitoring further afield immediately after the plant began leaking radioactivity."Since the first week of the disaster, authorities have slowly been announcing that they would start checking fish, seaweed, vegetables for radiation," said Tom Gill, a British professor of anthropology at Meiji Gakuin University who is studying communities in the disaster zone.
  • ...3 more annotations...
  • And the response in each case has - quite reasonably - to ask why it wasn't done previously," he said. "And this is no different."
  • As well as being slow to broaden the monitoring, Mr Gill says the figures being provided by the authorities are "extremely inconsistent."The education ministry, charged with compiling data, says on its web site that the maximum level of radiation in Fukushima Prefecture at present is 2.3 microsieverts per hour, while elsewhere on the same site it is showing a reading of 16.2 microsieverts in the hamlet of Nagadoro, on the edge of the exclusion zone.
  • Not only is that figure extremely high, but it's not going down," said Gill. "The village authorities' official line is that the residents will be able to go back in two years, and that might be so in some areas, but it is almost certainly out of the question for other areas."

The Thorium Reactor, A Nuclear Energy Alternative [19Sep11] - 0 views

  • After Fukushima a great deal of awareness on the dangers of nuclear energy has ignited a series of reactions in society, mainly a generalized rejection to nuclear energy and a call to develop cleaner and safer sources of energy. When thinking about nuclear energy mainly 2 sources come to peoples minds, solar and wind power condemning any sort of nuclear power.  Nuclear power has been associated with Weapons of Mass Destruction, radiation sickness and disease.  However, this is not due to the nuclear power itself but due to the nuclear fuel used to generate this nuclear power.
  • The above are just some of the most common byproducts, (better known as nuclear waste) of a nuclear fuel cycle, all of these substances are extremely poisonous, causing a variety of diseases, cancers and genetic mutations to the victim.  The worst part is that most of them remain in the environment of decades or even thousands of years, so if accidentally released to the environment they become a problem that future generations have to deal with.  Therefore, in nuclear energy the problem is in the fuel not in the engine. Lets start with the Thorium Reactors.  Thorium is a naturally occurring radioactive chemical element, found in abundance throughout the world.  It is estimated that every cubic meter of earth’s crust contains about 12 grams of this mineral, enough quantity to power 1 person’s electricity consumption for 12-25 years.  Energy is produced from thorium in a process known as the Thorium Fuel Cycle, were a nuclear fuel cycle is derived from the natural abundant isotope of thorium.
  • In today’s world the main fuel for nuclear power is a naturally occurring radioactive mineral, Uranium.  This mineral is one of the most dense metals in the periodic table which allows it to reach a chain reaction that can yield huge amounts of energy that can be exploited for an extended period of time.  Unfortunately the nuclear fuel cycle of Uranium produced extremely dangerous byproducts, commonly known as nuclear waste.  These are produced in liquid, solid and gaseous form in a wide variety of deadly substances, such as: Iodine 131 Strontium 90 Cesium 137 Euricium 155 Krypton 85 Cadmium 113 Tin 121 Samarium 151 Technetium-99
  • ...2 more annotations...
  • Thorium can be used as fuel in a nuclear reactor, and it is a fertile material, which allows it to be used to produce nuclear fuel in a breeder reactor.  These are some of the benefits of Thorium reactors compared to Uranium. Weapons-grade fissionable material is harder to retrieve safely and clandestinely from a thorium reactor; Thorium produces 10 to 10,000 times less long-lived radioactive waste; Thorium comes out of the ground as a 100% pure, usable isotope, which does not require enrichment, whereas natural uranium contains only 0.7% fissionable U-235; Thorium cannot sustain a nuclear chain reaction without priming,[22] so fission stops by default. The following conference by Kirk Sorensen explains a Liquid-Fuoride Thorium Reactor a next generation nuclear reactor.

The nuclear power plans that have survived Fukushima [28Sep11] - 0 views

  • SciDev.Net reporters from around the world tell us which countries are set on developing nuclear energy despite the Fukushima accident. The quest for energy independence, rising power needs and a desire for political weight all mean that few developing countries with nuclear ambitions have abandoned them in the light of the Fukushima accident. Jordan's planned nuclear plant is part of a strategy to deal with acute water and energy shortages.
  • The Jordan Atomic Energy Commission (JAEC) wants Jordan to get 60 per cent of its energy from nuclear by 2035. Currently, obtaining energy from neighbouring Arab countries costs Jordan about a fifth of its gross domestic product. The country is also one of the world's most water-poor nations. Jordan plans to desalinate sea water from the Gulf of Aqaba to the south, then pump it to population centres in Amman, Irbid, and Zarqa, using its nuclear-derived energy. After the Fukushima disaster, Jordan started re-evaluating safety procedures for its nuclear reactor, scheduled to begin construction in 2013. The country also considered more safety procedures for construction and in ongoing geological and environmental investigations.
  • The government would not reverse its decision to build nuclear reactors in Jordan because of the Fukushima disaster," says Abdel-Halim Wreikat, vice Chairman of the JAEC. "Our plant type is a third-generation pressurised water reactor, and it is safer than the Fukushima boiling water reactor." Wreikat argues that "the nuclear option for Jordan at the moment is better than renewable energy options such as solar and wind, as they are still of high cost." But some Jordanian researchers disagree. "The cost of electricity generated from solar plants comes down each year by about five per cent, while the cost of producing electricity from nuclear power is rising year after year," says Ahmed Al-Salaymeh, director of the Energy Centre at the University of Jordan. He called for more economic feasibility studies of the nuclear option.

  • And Ahmad Al-Malabeh, a professor in the Earth and Environmental Sciences department of Hashemite University, adds: "Jordan is rich not only in solar and wind resources, but also in oil shale rock, from which we can extract oil that can cover Jordan's energy needs in the coming years, starting between 2016 and 2017 ... this could give us more time to have more economically feasible renewable energy."
  • Finance, rather than Fukushima, may delay South Africa's nuclear plans, which were approved just five days after the Japanese disaster. South Africa remains resolute in its plans to build six new nuclear reactors by 2030. Katse Maphoto, the director of Nuclear Safety, Liabilities and Emergency Management at the Department of Energy, says that the government conducted a safety review of its two nuclear reactors in Cape Town, following the Fukushima event.
  • The Ninh Thuan nuclear plant would sit 80 to 100 kilometres from a fault line on the Vietnamese coast, potentially exposing it to tsunamis, according to state media. But Vuong Huu Tan, president of the state-owned Vietnam Atomic Energy Commission, told state media in March, however, that lessons from the Fukushima accident will help Vietnam develop safe technologies. And John Morris, an Australia-based energy consultant who has worked as a geologist in Vietnam, says the seismic risk for nuclear power plants in the country would not be "a major issue" as long as the plants were built properly. Japan's nuclear plants are "a lot more earthquake prone" than Vietnam's would be, he adds.
  • Larkin says nuclear energy is the only alternative to coal for generating adequate electricity. "What other alternative do we have? Renewables are barely going to do anything," he said. He argues that nuclear is capable of supplying 85 per cent of the base load, or constantly needed, power supply, while solar energy can only produce between 17 and 25 per cent. But, despite government confidence, Larkin says that a shortage of money may delay the country's nuclear plans.
  • The government has said yes but hasn't said how it will pay for it. This is going to end up delaying by 15 years any plans to build a nuclear station."
  • Vietnam's nuclear energy targets remain ambitious despite scientists' warning of a tsunami risk. Vietnam's plan to power 10 per cent of its electricity grid with nuclear energy within 20 years is the most ambitious nuclear energy plan in South-East Asia. The country's first nuclear plant, Ninh Thuan, is to be built with support from a state-owned Russian energy company and completed by 2020. Le Huy Minh, director of the Earthquake and Tsunami Warning Centre at Vietnam's Institute of Geophysics, has warned that Vietnam's coast would be affected by tsunamis in the adjacent South China Sea.
  • Undeterred by Fukushima, Nigeria is forging ahead with nuclear collaborations. There is no need to panic because of the Fukushima accident, says Shamsideen Elegba, chair of the Forum of Nuclear Regulatory Bodies in Africa. Nigeria has the necessary regulatory system to keep nuclear activities safe. "The Nigerian Nuclear Regulatory Authority [NNRA] has established itself as a credible organisation for regulatory oversight on all uses of ionising radiation, nuclear materials and radioactive sources," says Elegba who was, until recently, the NNRA's director general.
  • Vietnam is unlikely to experience much in the way of anti-nuclear protests, unlike neighbouring Indonesia and the Philippines, where civil society groups have had more influence, says Kevin Punzalan, an energy expert at De La Salle University in the Philippines. Warnings from the Vietnamese scientific community may force the country's ruling communist party to choose alternative locations for nuclear reactors, or to modify reactor designs, but probably will not cause extreme shifts in the one-party state's nuclear energy strategy, Punzalan tells SciDev.Net.
  • But the government adopted its Integrated Resource Plan (IRP) for 2010-2030 five days after the Fukushima accident. Elliot Mulane, communications manager for the South African Nuclear Energy Corporation, (NECSA) a public company established under the 1999 Nuclear Energy Act that promotes nuclear research, said the timing of the decision indicated "the confidence that the government has in nuclear technologies". And Dipuo Peters, energy minister, reiterated the commitment in her budget announcement earlier this year (26 May), saying: "We are still convinced that nuclear power is a necessary part of our strategy that seeks to reduce our greenhouse gas emissions through a diversified portfolio, comprising some fossil-based, renewable and energy efficiency technologies". James Larkin, director of the Radiation and Health Physics Unit at the University of the Witwatersrand, believes South Africa is likely to go for the relatively cheap, South Korean generation three reactor.
  • In the meantime, the government is trying to build capacity. The country lacks, for example, the technical expertise. Carmencita Bariso, assistant director of the Department of Energy's planning bureau, says that, despite the Fukushima accident, her organisation has continued with a study on the viability, safety and social acceptability of nuclear energy. Bariso says the study would include a proposal for "a way forward" for the Bataan Nuclear Power Plant, the first nuclear reactor in South East Asia at the time of its completion in 1985. The $2.3-billion Westinghouse light water reactor, about 60 miles north of the capital, Manila, was never used, though it has the potential to generate 621 megawatts of power. President Benigno Aquino III, whose mother, President Corazon Aquino, halted work on the facility in 1986 because of corruption and safety issues, has said it will never be used as a nuclear reactor but could be privatised and redeveloped as a conventional power plant.
  • But Mark Cojuangco, former lawmaker, authored a bill in 2008 seeking to start commercial nuclear operations at the Bataan reactor. His bill was not passed before Congress adjourned last year and he acknowledges that the Fukushima accident has made his struggle more difficult. "To go nuclear is still the right thing to do," he says. "But this requires a societal decision. We are going to spark public debates with a vengeance as soon as the reports from Fukushima are out." Amended bills seeking both to restart the reactor, and to close the issue by allowing either conversion or permanent closure, are pending in both the House and the Senate. Greenpeace, which campaigns against nuclear power, believes the Fukushima accident has dimmed the chances of commissioning the Bataan plant because of "increased awareness of what radioactivity can do to a place". Many parts of the country are prone to earthquakes and other natural disasters, which critics say makes it unsuitable both for the siting of nuclear power stations and the disposal of radioactive waste.
  • In Kenya, nuclear proponents argue for a geothermal – nuclear mix In the same month as the Fukushima accident, inspectors from the International Atomic Energy Agency approved Kenya's application for its first nuclear power station (31 March), a 35,000 megawatt facility to be built at a cost of Sh950 billion (US$9.8 billion) on a 200-acre plot on the Athi Plains, about 50km from Nairobi
  • The plant, with construction driven by Kenya's Nuclear Electricity Project Committee, should be commissioned in 2022. The government claims it could satisfy all of Kenya's energy needs until 2040. The demand for electricity is overwhelming in Kenya. Less than half of residents in the capital, Nairobi, have grid electricity, while the rural rate is two per cent. James Rege, Chairman of the Parliamentary Committee on Energy, Communication and Information, takes a broader view than the official government line, saying that geothermal energy, from the Rift Valley project is the most promising option. It has a high production cost but remains the country's "best hope". Nuclear should be included as "backup". "We are viewing nuclear energy as an alternative source of power. The cost of fossil fuel keeps escalating and ordinary Kenyans can't afford it," Rege tells SciDev.Net.
  • Hydropower is limited by rivers running dry, he says. And switching the country's arable land to biofuel production would threaten food supplies. David Otwoma, secretary to the Energy Ministry's Nuclear Electricity Development Project, agrees that Kenya will not be able to industrialise without diversifying its energy mix to include more geothermal, nuclear and coal. Otwoma believes the expense of generating nuclear energy could one day be met through shared regional projects but, until then, Kenya has to move forward on its own. According to Rege, much as the nuclear energy alternative is promising, it is extremely important to take into consideration the Fukushima accident. "Data is available and it must be one step at a time without rushing things," he says. Otwoma says the new nuclear Kenya can develop a good nuclear safety culture from the outset, "but to do this we need to be willing to learn all the lessons and embrace them, not forget them and assume that won't happen to us".
  • Will the Philippines' plans to rehabilitate a never-used nuclear power plant survive the Fukushima accident? The Philippines is under a 25-year moratorium on the use of nuclear energy which expires in 2022. The government says it remains open to harnessing nuclear energy as a long-term solution to growing electricity demand, and its Department of Science and Technology has been making public pronouncements in favour of pursuing nuclear energy since the Fukushima accident. Privately, however, DOST officials acknowledge that the accident has put back their job of winning the public over to nuclear by four or five years.
  • It is not only that we say so: an international audit came here in 2006 to assess our procedure and processes and confirmed the same. Elegba is firmly of the view that blame for the Fukushima accident should be allocated to nature rather than human error. "Japan is one of the leaders not only in that industry, but in terms of regulatory oversight. They have a very rigorous system of licensing. We have to make a distinction between a natural event, or series of natural events and engineering infrastructure, regulatory infrastructure, and safety oversight." Erepamo Osaisai, Director General of the Nigeria Atomic Energy Commission (NAEC), has said there is "no going back" on Nigeria's nuclear energy project after Fukushima.
  • Nigeria is likely to recruit the Russian State Corporation for Atomic Energy, ROSATOM, to build its first proposed nuclear plant. A delegation visited Nigeria (26- 28 July) and a bilateral document is to be finalised before December. Nikolay Spassy, director general of the corporation, said during the visit: "The peaceful use of nuclear power is the bedrock of development, and achieving [Nigeria's] goal of being one of the twenty most developed countries by the year 2020 would depend heavily on developing nuclear power plants." ROSATOM points out that the International Atomic Energy Agency monitors and regulates power plant construction in previously non-nuclear countries. But Nnimmo Bassey, executive director of the Environmental Rights Action/Friends of the Earth Nigeria (ERA/FoEN), said "We cannot see the logic behind the government's support for a technology that former promoters in Europe, and other technologically advanced nations, are now applying brakes to. "What Nigeria needs now is investment in safe alternatives that will not harm the environment and the people. We cannot accept the nuclear option."
  • Thirsty for electricity, and desirous of political clout, Egypt is determined that neither Fukushima ― nor revolution ― will derail its nuclear plans. Egypt was the first country in the Middle East and North Africa to own a nuclear programme, launching a research reactor in 1961. In 2007 Egypt 'unfroze' a nuclear programme that had stalled in the aftermath of the Chernobyl disaster. After the Egyptian uprising in early 2011, and the Fukushima accident, the government postponed an international tender for the construction of its first plant.
  • Yassin Ibrahim, chairman of the Nuclear Power Plants Authority, told SciDev.Net: "We put additional procedures in place to avoid any states of emergency but, because of the uprising, the tender will be postponed until we have political stability after the presidential and parliamentary election at the end of 2011". Ibrahim denies the nuclear programme could be cancelled, saying: "The design specifications for the Egyptian nuclear plant take into account resistance to earthquakes and tsunamis, including those greater in magnitude than any that have happened in the region for the last four thousand years. "The reactor type is of the third generation of pressurised water reactors, which have not resulted in any adverse effects to the environment since they began operation in the early sixties."
  • Ibrahim El-Osery, a consultant in nuclear affairs and energy at the country's Nuclear Power Plants Authority, points out that Egypt's limited resources of oil and natural gas will run out in 20 years. "Then we will have to import electricity, and we can't rely on renewable energy as it is still not economic yet — Egypt in 2010 produced only two per cent of its needs through it." But there are other motives for going nuclear, says Nadia Sharara, professor of mineralogy at Assiut University. "Owning nuclear plants is a political decision in the first place, especially in our region. And any state that has acquired nuclear technology has political weight in the international community," she says. "Egypt has the potential to own this power as Egypt's Nuclear Materials Authority estimates there are 15,000 tons of untapped uranium in Egypt." And she points out it is about staying ahead with technology too. "If Egypt freezes its programme now because of the Fukushima nuclear disaster it will fall behind in many science research fields for at least the next 50 years," she warned.

Fukushima 'alarm': Ground cracking, radioactive steam seeping (Video) [15Aug11] - 0 views

  • As Canadians learned about dangerous radiation falling on them in rain on Tuesday as far east as Toronto registered at 20,000 CPM, equivalent to the highly targeted dose of radiation for cancer radiotherapy,  the Fukushima catastrophe escalated even higher Wednesday with evidence that the ground is cracking under the crippled nuclear power plant, causing radioactive steam to escape, "very serious and alarming" according to Anissa Naouai's guest on Russia Today, Dr. Robert Jacobs, Professor of nuclear history at Hiroshima Peace Institute. 
  • Fukushima nuclear plant workers have reported that the ground under the facility is cracking and radioactive steam is already escaping through the cracks that Dr. Jacobs says is very serious and alarming development because it has happened after two large earthquakes over the past few weeks according to Russia Today. (See embedded Russia Today interviewing Dr. Jacobs on Youtube video on this page left.) "There was a 6.4 earthquake on the 31st of July and a 6.0 earthquake on August 12th," Dr. Jacobs told Russia Today's Naoiai.
  • "What this indicates is there may have been some breaking of the pipes and some of the structures underground that happened during these earthquakes," he said. "There could be radioactive water that is venting into the soil and what's more, as cracks are opening, the steam and radioactivity is working its way up," he said.

  • Now it is known that radioactive material, the melted core, is moving under the ground away from where it the measuring was being done according to Dr. Jacobs. He said that the reactors were not safe for earthquakes and there is evidence that Reactor #1 was melting down when the tsunami hit, putting reliability in question. 
  • There are continual aftershocks at the level of a 6.0, so when you have a fragile structure and what we have now, the radioactive core has melted down into the basement, into the bottom of the containment vessel. 
  • Russia Today reporting that new evidence suggests Fukushima's nuclear reactors were doomed to cripple even before the massive wave reached them adds weight to the unreliability of nuclear energy according to Dr. Jacobs. Canadians receiving extreme radiation in Tuesday rainout

Scosche Launches Radiation Detector and App for iPhone and iPod touch [31Aug11] - 0 views

  • Scosche Industries, award-winning innovator of consumer technology, is excited to announce the RDTX-PRO radiation detector and app for iPhone and iPod touch. The radiation detector requires no calibration and allows users to accurately detect gamma radiation above 60keV within +/- 5% accuracy.  The device attaches to an iPhone or iPod touch via the dock connection and is extremely compact for ease of use.  It can also be used as a radiation alarm independently from the iOS device.  When being used as a standalone alarm the RDTX-PRO runs on one AA battery and provides up to 96 hour of radiation detection. “I was extremely impressed with the accuracy and performance of the RDTX-PRO from Scosche,” said Julius James, Radiation Specialist of Fluke Global Calibration Laboratories.  “The detector is as accurate as units that cost significantly more and is much smaller in size.” After connecting the Scosche RDTX-PRO with an iPhone or iPod touch users are prompted to download the free accompanying radTEST app.  The app offers a consumer friendly meter display that shows radiation levels as safe (green), elevated (yellow) or dangerous (red).  For the advanced user the digital display mode can be used to determine exact radiation levels.   Users can also share their results using Facebook, Twitter and Google Maps.
  • The Scosche RDTX-PRO retail for $329.99 and will be available in September from Synexx in Tokyo Japan.  $10 of each unit sold will be donated to a group of charities with a goal of reaching 1 million dollars within two years.  The charities include the Bikki Children’s Fund, Samaritan’s Purse, All Hands Volunteers, and others committed to aiding those that were affected by the Tohoku Earthquake and Tsunami.

Senate Appropriators on Nuclear Energy [16Sep11] - 0 views

shared by D'coda Dcoda on 09 Oct 11 - No Cached
  • The Senate Energy and Water Development Appropriations Subcommittee included extensive language in their FY 2012 committee report about nuclear energy.  They wrote of being “extremely concerned that the United States continues to accumulate spent fuel from nuclear reactors without a comprehensive plan to collect the fuel or dispose of it safely, and as a result faces a $15,400,000,000 liability by 2020,” called for the development of “consolidated regional storage facilities,” and mandated research on dry cask storage, advanced fuel cycle options, and disposal in geological media.  The appropriators provided no funding for the Next Generation Nuclear Plant program or Light Water Reactor Small Modular Reactor Licensing Technical Support.  In a separate section, they direct the Nuclear Regulatory Commission to contract with the National Academy of Sciences for a study on the lessons learned from the Fukushima nuclear disaster, and discuss beyond design-basis events and mitigating impacts of earthquakes. Language from the committee report 112-75 follows, with page number references to the pdf version of this document.

Although the Committee has provided sufficient time for these issues to be resolved, the program has stalled. Recognizing funding constraints, the Committee cannot support continuing the program in its current form. The Committee provides no funding to continue the existing NGNP program, but rather allows the Department to continue high-value, priority research and development activities for high-temperature reactors, in cooperation with industry, that were included in the NGNP program.”

  • “While the Nuclear Regulatory Commission has found that spent nuclear fuel can be stored safely for at least 60 years in wet or dry cask storage beyond the licensed life of the reactor, the Committee has significant questions on this matter and is extremely concerned that the United States continues to accumulate spent fuel from nuclear reactors without a comprehensive plan to collect the fuel or dispose of it safely, and as a result faces a $15,400,000,000 liability by 2020. The Committee approved funding in prior years for the Blue Ribbon Commission on America’s Nuclear Future [BRC], which was charged with examining our Nation’s policies for managing the back end of the nuclear fuel cycle and recommending a new plan. The BRC issued a draft report in July 2011 with recommendations, which is expected to be finalized in January 2012. The Committee directs prior existing funding, contingent on the renewal of its charter, to the BRC to develop a comprehensive revision to Federal statutes based on its recommendations, to submit to Congress for its consideration.
  • “The Committee directs the Department to develop and prepare to implement a strategy for the management of spent nuclear fuel and other nuclear waste within 3 months of publication of the final report of the Blue Ribbon Commission on America’s Nuclear Future.  The strategy shall reduce long-term Federal liability associated with the Department’s failure to pick up spent fuel from commercial nuclear reactors, and it should propose to store waste in a safe and responsible manner. The Committee notes that a sound Federal strategy will likely require one or more consolidated storage facilities with adequate capacity to be sited, licensed, and constructed in multiple regions, independent of the schedule for opening a repository. The Committee directs that the Department’s strategy include a plan to develop consolidated regional storage facilities in cooperation with host communities, as necessary, and propose any amendments to Federal statute necessary to implement the strategy.
  • “Although successfully disposing of spent nuclear fuel permanently is a long-term effort and will require statutory changes, the Committee supports taking near- and mid-term steps that can begin without new legislation and which provide value regardless of the ultimate policy the United States adopts. The Committee therefore includes funding for several of these steps in the Nuclear Energy Research and Development account, including the assessment of dry casks to establish a scientific basis for licensing; continued work on advanced fuel cycle options; research to assess disposal in different geological media; and the development of enhanced fuels and materials that are more resistant to damage in reactors or spent fuel pools.
  • (Page 80) “The events at the Fukushima-Daiichi facilities in Japan have resulted in a reexamination of our Nation’s policies regarding the safety of commercial reactors and the storage of spent nuclear fuel.  These efforts have been supported by appropriations in this bill, and the Committee provides funding for continuation and expansion of these activities.
  • The report also contains extensive language regarding Nuclear Energy Research and Development: “Use of Prior Existing Balances. - If the Secretary renews the charter of the Blue Ribbon Commission, the Department is directed to use $2,500,000 of prior existing balances appropriated to the Office of Civilian Radioactive Waste Management to develop a comprehensive revision to Federal statutes based on its recommendations.  The recommendation should be provided to Congress not later than March 30, 2012 for consideration.
  • “Nuclear Energy Enabling Technologies. - The Committee recommends $68,880,000 for Nuclear Energy Enabling Technologies, including $24,300,000 for the Energy Innovation Hub for Modeling and Simulation, $14,580,000 for the National Science User Facility at Idaho National Laboratory, and $30,000,000 for Crosscutting research.  The Committee does not recommend any funding for Transformative research. The Committee recommends that the Department focus the Energy Innovation Hub on the aspects of its mission that improve nuclear powerplant safety.
  • Light Water Reactor Small Modular Reactor Licensing Technical Support. - The Committee provides no funding for Light Water Reactor Small Modular Reactor Licensing Technical Support. “Reactor Concepts Research, Development, and Demonstration. - The Committee provides $31,870,000 for Reactor Concepts Research, Development and Demonstration. Of this funding, $21,870,000 is for Advanced Reactor Concepts activities. The Committee does not include funding for the Next Generation Nuclear Plant Demonstration project. The Department may, within available funding, continue high-value, priority research and development activities for high-temperature reactor concepts, in cooperation with industry, that were conducted as part of the NGNP program.  The remaining funds, $10,000,000, are for research and development of the current fleet of operating reactors to determine how long they can safely operate.
  • “Fuel Cycle Research and Development. - The Committee recommends $187,917,000 for Fuel Cycle Research and Development.  Within available funds, the Committee provides $10,000,000 for the Department to expand the existing modeling and simulation capabilities at the national laboratories to assess issues related to the aging and safety of storing spent nuclear fuel in fuel pools and dry storage casks. The Committee includes $60,000,000 for Used Nuclear Fuel Disposition, and directs the Department to focus research and development activities on the following priorities: $10,000,000 for development and licensing of standardized transportation, aging, and disposition canisters and casks; $3,000,000 for development of models for potential partnerships to manage spent nuclear fuel and high level waste; and $7,000,000 for characterization of potential geologic repository media.
  • “The Committee provides funding for evaluation of standardized transportation, aging and disposition cask and canister design, cost, and safety characteristics, in order to enable the Department to determine those that should be used if the Federal Government begins transporting fuel from reactor sites, as it is legally obligated to do, and consolidating fuel. The Committee notes that the Blue Ribbon Commission on America’s Nuclear Future has, in its draft report, recommended the creation of consolidated interim storage facilities, for which the Federal Government will need casks and canisters to transport and store spent fuel.

Fracking - energy revolution or skillfully marketed mirage? [27Jun11] - 0 views

  • The New York Times published an article on Sunday, June 26, 2011 titled Insiders Sound an Alarm Amid a Natural Gas Rush. The article quotes a number of emails from natural gas industry insiders, financial analysts that cover the gas industry and skeptical geologists to produce a number of questions about the long term viability of an increasing dependence on cheap natural gas from hydraulic fracturing. The message is that the gas industry has been engaging in hyperbole regarding its capacity to expand production at current prices to meet market demands.
  • the people quoted in the NY Times article do not agree that the technique magically produces low cost gas in unprecedented abundance.
  • “Our engineers here project these wells out to 20-30 years of production and in my mind that has yet to be proven as viable,” wrote a geologist at Chesapeake in a March 17 e-mail to a federal energy analyst. “In fact I’m quite skeptical of it myself when you see the % decline in the first year of production.”
  • ...12 more annotations...
  • “In these shale gas plays no well is really economic right now,” the geologist said in a previous e-mail to the same official on March 16. “They are all losing a little money or only making a little bit of money.”
  • Around the same time the geologist sent the e-mail, Mr. McClendon, Chesapeake’s chief executive, told investors, “It’s time to get bullish on natural gas.”
  • Aubrey McClendon, whose name is not terribly familiar to people outside of the energy industry, has an enormous financial interest in encouraging customers to become addicted to natural gas so that they will keep buying even if the price shoots up – like it did in the period from 2000-2008. During that time McClendon and his company rode a wave that resulted in growing a company from tiny to huge based on debt-financed investments in leases and drilling rigs designed to produce gas in the midcontinent region of the US. A high portion of the company’s wells were stimulated with hydraulic fracturing.
  • When the price of natural gas collapsed in 2008, mostly as a result of the contraction in demand caused by the financial crisis and resulting economic recession/depression, McClendon nearly lost control of his company. He had to sell “substantially all” of shares at a dramatically lowered price in order to pay off creditors and meet margin calls.
  • No U.S. chief executive officer has bought more of his own company’s stock in recent years than McClendon, even as the shares reached all-time highs. His appetite for Chesapeake stock made him “a darling of Wall Street,” Tulsa money manager Jake Dollarhide said. But his purchases were made on margin, meaning he used borrowed money. As the value of the stock fell, McClendon was forced to raise cash to meet margin calls. Recent losses — Chesapeake shares have plummeted 60 percent in the past three weeks — left him unable to fulfill those requirements.Read more: http://newsok.com/market-slide-wipes-out-ceos-chesapeake-holdings/article/3310107#ixzz1QSst9NnL
  • McClendon responded vigorously to the NY Times’s suggestion that the gas revolution was more mirage than miracle in a lengthy letter to Chesapeake Energy employees that was published on the company’s public Facebook page. (Note: The timing of this letter with regard to the NY Times article is telling. The article appeared in the Sunday edition of the Times on June 26, 2011. The letter to employees included a time stamp indicating that it was released at 8:37 pm on the same day while the Facebook page indicates that it was posted to the world by 11:27 pm. In other words – there is no rest for the weary in the Internet era.)
  • McClendon’s letter blamed the NY Times article on environmental activists that proclaim a desire to supply all of the US energy needs from wind and solar energy. It also issued a call to action for Chesapeake Energy employees:
  • We hope that every Chesapeake employee can be part of our public education outreach. At more than 11,000 strong, we are an army of “factivists” – people who have knowledge of the facts and the personal knowledge and ability to spread them. You can do this by talking to your families, friends and others in your spheres of influence (schools, churches, civic organizations, etc) about the kind of company you work for and the integrity of what we do every day for our shareholders, our communities, our states, our nation, our economy and our environment. You don’t have to be an expert to stand up and tell folks that Chesapeake is committed to doing what’s right – and that commitment is expressed every day by you and your colleagues across the company.
  • You can also get involved by joining Chesapeake Fed PAC, our political action committee. Our opponents are extremely well funded and organized. We need to make sure our voice is heard in Washington, DC and with elected officials who are making decisions that affect our industry, our company and our ability to operate in the many states in which shale gas and oil have been discovered.
  • After describing how Chesapeake has 125 active drilling rigs and how it has developed a “swat team” with more than 100 employees that works with environmental groups to produce legislation designed to slow the development of new coal fired power plants and to hasten the closure of existing coal plants, Tom Price said the following:
  • “It’s been said before, but the demand side of the equation is extremely important right now. I mean this really is a zero sum game. I think that there are a number of very progressive utilities out there that recognize the challenges that they are facing with regard to climate change, but the Transport Rule, Clean Air Act and various others.”
  • I remain convinced that there is a market battle going on between natural gas and nuclear energy.

Physician: International medical community must immediately assist Japanese - Radioacti... - 1 views

  • : Dr. Helen Caldicott
  • All areas of Japan should be tested to assess how radioactive the soil and water are because the winds can blow the radioactive pollution hundreds of miles from the point source at Fukushima. Under no circumstances should radioactive rubbish and debris be incinerated as this simply spreads the isotopes far and wide to re-concentrate in food and fish. All batches of food must be adequately tested for specific radioactive elements using spectrometers. No radioactive food must be sold or consumed, nor must radioactive food be diluted for sale with non-radioactive food as radioactive elements re-concentrate in various bodily organs. All water used for human consumption should be tested weekly. All fish caught off the east coast must be tested for years to come. All people, particularly children, pregnant women and women of childbearing age still living in high radiation zones should be immediately evacuated to non-radioactive areas of Japan. All people who have been exposed to radiation from Fukushima – particularly babies, children, immunosuppressed, old people and others — must be medically thoroughly and routinely examined for malignancy, bone marrow suppression, diabetes, thyroid abnormalities, heart disease, premature aging, and cataracts for the rest of their lives and appropriate treatment instituted. Leukemia will start to manifest within the next couple of years, peak at five years and solid cancers will start appearing 10 to 15 years post-accident and will continue to increase in frequency in this generation over the next 70 to 90 years. All physicians and medical care providers in Japan must read and examine Chernobyl–Consequences of the Catastrophe for People and the Environment by the New York Academy of Sciences to understand the true medical gravity of the situation they face. I also suggest with humility that doctors in particular but also politicians and the general public refer to my web page, nuclearfreeplanet.org for more information, that they listen to the interviews related to Fukushima and Chernobyl on my radio program at ifyoulovethisplanet.org and they read my book NUCLEAR POWER IS NOT THE ANSWER. The international medical community and in particular the WHO must be mobilized immediately to assist the Japanese medical profession and politicians to implement this massive task outlined above. The Japanese government must be willing to accept international advice and help. As a matter of extreme urgency Japan must request and receive international advice and help from the IAEA and the NRC in the U.S., and nuclear specialists from Canada, Europe, etc., to prevent the collapse of Fukushima Dai-ichi Unit 4 and the spent fuel pool if there was an earthquake greater than 7 on the Richter scale.As the fuel pool crashed to earth it would heat and burn causing a massive radioactive release 10 times larger than the release from Chernobyl. There is no time to spare and at the moment the world community sits passively by waiting for catastrophe to happen. The international and Japanese media must immediately start reporting the facts from Japan as outlined above. Not to do so is courting global disaster.

Whistle-blower talks, container vessel is melting like honeycomb [03Jan11] - 0 views

  • A whistle-blower of Tepco leaked the actual situation of Fukushima plant. He left his comments on a Japanese forum. Here are the messages.
  • Boring survey around reactor 2 is coming to the climax. As a result, the announcement of the government and Tepco has to be denied. If it’s soft material, they can do horizontal boring with such a weak equipment (like the top picture ) but when it comes to the concrete of the reactor building it’s impossible. They need to do boring with a foreign heavy equipment at an angle. They do boring to reach to under the container vessel. (like the bottom 2 pictures)
  • When they do boring where they don’t need to take a sample they drill roughly with this green rotary diamond bit but the dust is lethal because it’s too radioactive. When they need to take a sample, they change the diamond bit to hole saw type of bit. However, diamond is weak for the heat so when it’s hotter than 500℃ they use the standard type of the tungsten carbide instead.    The bottom 3 pictures are the samples taken.

  • Probably the iron part of the core is uranium pellet unreacted – not sure yet because it’s still before the analysis. It’s beyond the max reading of 500X100 CPM. These yellow concrete slags come out from under the building one after one. It means that the container vessel is melting like honeycomb at least – doesn’t it? Otherwise why would metal uranium comes out of there ?
  • Taking a part of the concrete slag sample. Put it into the lead case (Chiyoda technol) and take it to a lab. I don’t know if it’s because they gave sea water to cool down or because it’s brackish area, if natrium (sodium salt) of sea water made a chemical reaction with calcium carbonate in the concrete to become diuranate natrium (sodium diuranate) or not, it looks yellow as yellow cake
  • made up my mind to take out the slags from the shelter to take pictures of them. wore protective clothing. When it’s taken out, it was over 400 ℃ but now it’s cooled down to 100 ℃. Can you see this big metal crystal (extremely radioactive) and the oxidized concrete looking like yellow cake? Can you believe it is out of the container vessel. It’s over 500 mSv/h, my geiger counter went over the limit. was scared so put it back to the shelter soon as I took a couple of the pictures.

'Absolutely No Progress Being Made' at Fukushima Nuke Plant, Undercover Reporter Says [... - 0 views

  • "Absolutely no progress is being made" towards the final resolution of the crisis, Suzuki told reporters at a Foreign Correspondents' Club of Japan news conference on Dec. 15. Suzuki, 55, worked for a Toshiba Corp. subsidiary as a general laborer there from July 13 to Aug. 22, documenting sloppy repair work, companies including plant operator Tokyo Electric Power Co. (TEPCO) playing fast and loose with their workers' radiation doses, and a marked concern for appearances over the safety of employees or the public.
  • For example, the no-entry zones around the plant -- the 20-kilometer radius exclusion zone and the extension covering most of the village of Iitate and other municipalities -- have more to do with convenience that actual safety, Suzuki says. "(Nuclear) technology experts I've spoken to say that there are people living in areas where no one should be. It's almost as though they're living inside a nuclear plant," says Suzuki. Based on this and his own radiation readings, he believes the 80-kilometer-radius evacuation advisory issued by the United States government after the meltdowns was "about right," adding that the government probably decided on the current no-go zones to avoid the immense task of evacuating larger cities like Iwaki and Fukushima.
  • The situation at the plant itself is no better, where he says much of the work is simply "for show," fraught with corporate jealousies and secretiveness and "completely different" from the "all-Japan" cooperative effort being presented by the government.
  • ...3 more annotations...
  • "Reactor makers Toshiba and Hitachi (brought in to help resolve the crisis) each have their own technology, and they don't talk to each other. Toshiba doesn't tell Hitachi what it's doing, and Hitachi doesn't tell Toshiba what it's doing." Meanwhile, despite there being no concrete data on the state of the reactor cores, claims by the government and TEPCO that the disaster is under control and that the reactors are on-schedule for a cold shutdown by the year's end have promoted a breakneck work schedule, leading to shoddy repairs and habitual disregard for worker safety, he said.
  • "Working at Fukushima is equivalent to being given an order to die," Suzuki quoted one nuclear-related company source as saying. He says plant workers regularly manipulate their radiation readings by reversing their dosimeters or putting them in their socks, giving them an extra 10 to 30 minutes on-site before they reach their daily dosage limit. In extreme cases, Suzuki said, workers even leave the radiation meters in their dormitories.
  • According to Suzuki, TEPCO and the subcontractors at the plant never explicitly tell the workers to take these measures. Instead the workers are simply assigned projects that would be impossible to complete on time without manipulating the dosage numbers, and whether through a sense of duty or fear of being fired, the workers never complain. Furthermore, the daily radiation screenings are "essentially an act," with the detector passed too quickly over each worker, while "the line to the buzzer that is supposed to sound when there's a problem has been cut," Suzuki said.

Canadian Medical Association Journal Blasts Japanese Government: "Culture of Coverup" E... - 0 views

  • The official journal of the Canadian Medical Association (CMA), "Canadian Medical Association Journal" is a peer-reviewed scientific journal. On their website, there is an article dated December 21, 2011 which severely criticizes the Japanese government's response (or lack thereof) to the nuclear disaster which has just been declared "over" by the current Noda administration.Written by Lauren Vogel of CMAJ quoting medical experts, the article states:The Japanese government has been "lying through their teeth" ever since the March 11 accident;The Japanese government hasn't disclosed enough information for the citizens to make informed decision, with “extreme lack of transparent, timely and comprehensive communication”;
  • The response to the Fukushima nuclear disaster by the Japanese government is far worse than the response to the Chernobyl accident by the Soviet Union government;The annual radiation exposure limit for the general public of 20 millisieverts is "unconscionable", and there has been no government "in recent decades that's been willing to accept such a high level of radiation-related risk for its population"

Thorium, Not The Nuclear Savior Claimed [14Sep11] - 0 views

  • The misinformation on thorium is highly promoted by the nuclear industry and various companies that want investment dollars for thorium reactors and fuel
  • One myth is that thorium is safe. Thorium-232 has a half life of 14 billion years (billions, not millions). Thorium-232 is also highly radiotoxic, with the same amount of radioactivity of uranium and thorium, thorium produces a far higher dose in the body. If someone inhaled an amount of thorium the bone surface dose is 200 times higher than if they inhaled the same amount of uranium. Thorium also requires longer spent fuel storage than uranium. With the daughter products of thorium like technetium‐99 with a half life of over 200,000 years, thorium is not safe nor a solution to spent fuel storage issues.
  • Another myth is that thorium reactors can run at atmospheric temperatures, in order to produce power they must be run differently and would not be at atmospheric temperatures. Many of the thorium reactors use liquid sodium fluoride in the reactor process. This material is highly toxic and has its own series of risks. The creation of thorium fuels is also not safer than creating uranium fuels. Thorium poses the same nuclear waste and toxic substance problems found in mining and fuel milling of uranium.
  • ...4 more annotations...
  • Thorium power production has been experimented with for over 50 years. Thorium breeder reactors have been experimented with but have technical issues and breed fuel at lower rates than tradiational breeder reactors. It is frequently claimed that India has a bunch of successful thorium commercial power reactors. The reality is that India has been trying for decades and still has not developed a commercial thorium reactor. Thorium is also not more economical to run. The fuel cycle is more costly and the needed protections for workers, plant safety and the public are considerably more than existing fuels.
  • The Germans experimented with a Thorium reactor, the THTR-300. They found even with the thorium reactor there were substantial risks in a loss of coolant event. They also had issues with concrete structures failing due to extremely high heat, fracturing thorium fuel and hot spots in the reactor. There was also a radioactive release into the air due to a malfunction. The reactor was eventually scrapped due to technical problems and costs.
  • Another rather silly claim going around is that “thorium is so safe you can handle it with your bare hands!”. Sorry, but you can do the same thing with a uranium fuel pellet.
