EnergySoultions Contracts with Studsvik for Nuclear Waste Processing [10Feb11] - 0 views

  • EnergySolutions Inc. is making a deal with a Sweden-based competitor, Studsvik, to dispose of solid nuclear waste in Utah. The Deseret News of Salt Lake City reported Tuesday that EnergySolutions signed a contract in December with Studsvik Inc. That's a U.S. subsidiary of Sweden's Studsvik Holding.
  • The plan is to use the company's THOR (Thermal volume/Weight Reduction Technology) to process nuclear power plant waste into solid form rather than a mix of powdery, radioactive resins.
  • Studsvik's patented technology features a pyrolysis / steam reforming system to volume and mass reduce organic waste streams to a non-reactive waste form for efficient Disposal or On-site Storage. Bead Resins, Powdered Filter Medias, Sludges, Activated Charcoal, Non-Metal Filter Cartridges, and Dry Active Wastes (DAW) all have been successfully processed. This entire process is referred to as Thermal Organic Reduction or THOR.

  • After processing at Studsvik's facility in Erwin, Tenn., the waste will be disposed of at EnergySolutions' plant in Tooele County, about 80 miles west of Salt Lake City.
  • Officials say the final product doesn't exceed the low-level class A radioactivity limits that the EnergySolutions Utah facility is licensed to accept

#Radiation in Japan: Practically Any Radioactive Debris Will Be Burned and Buried [11Au... - 0 views

  • From Yomiuri Shinbun
  • On August 10, the Ministry of the Environment made public the base plan for the ashes from burning the debris and sludge that contain radioactive materials from the Fukushima I Nuclear Power Plant accident. The plan would technically allow all the ashes to be buried.
  • ...5 more annotations...
  • The whole plan is moot, because, on the side, the ministry has already told municipalities that they can "mix and match" - burn radioactive debris and sludge with non-radioactive debris and sludge to lower the radiation below whatever the limit the ministry sets, which has been 8,000 becquerels/kg and now 100,000 becquerels/kg if the plan gets an approval from the expert committee. The ministry set the limit for Fukushima Prefecture, then notified other prefectures to "refer to the Ministry's instruction to Fukushima Prefecture and notify the municipalities accordingly".
  • In June, the ministry announced that the ashes that test up to 8,000 becquerels/kg of radioactive cesium can be buried in the final disposal facilities. It called for the temporary storage of the ashes that exceed 8,000 becquerels/kg but didn't specify the final disposal procedure. In the base plan announced on August 10, to bury the ashes whose radioactive cesium exceeds 8,000 becquerels/kg, some measures need to be taken to prevent radioactive cesium from making contact with ground water, or to process the runoff appropriately. For the ashes that measure 8,000 to 100,000 becquerels/kg, the plan calls for: 1) processing facilities with roofs; 2) durable containers; 3) mixing the ashes with cement to solidify.
  • The plan was given on the same day to the ministry's committee of experts to evaluate the safety of disaster debris disposal, and the ministry hopes to finalize the plan before the end of August.
  • The Ministry of the Environment, which is likely to be selected as the new regulatory authority over the nuclear industry in Japan, is not very known for timely disclosure of information online. This base plan, if it is announced on their site, is buried so well that I can't find it. The latest information on the earthquake/tsunami disaster debris is dated July 28, which specified the "temporary" storage of the ashes that exceed 8,000 becquerels/kg of radioactive cesium.
  • It looks like the ministry is simply making this "temporary" storage into permanent.

Nuclear waste requires a cradle-to-grave strategy, study finds [27Aug11] - 0 views

  • ScienceDaily (July 3, 2010) — after Fukushima, it is now imperative to redefine what makes a successful nuclear energy–from the cradle to the grave. If the management of nuclear waste is not considered by the authority, the public in many countries reject nuclear energy as an option, according to a survey appearing in the Bulletin of Atomic Scientists, published by SAGE.
  • According to Allison Macfarlane, Associate Professor of environmental science and policy at George Mason University and a member of the Blue Ribbon for nuclear future of America, resulting in storage for nuclear waste, which is still a last-minute decision to a number of countries outside of Japan. It is surprisingly common for reactor sites for overburdened with spent nuclear fuel without any clear plan. In South Korea, for example, saving to four nuclear power stations in the nation is filled, leading to a crisis within the storage potential of the next decade.
  • United Arab Emirates broke the ground for the first of four nuclear reactors on 14 March 2011, but has not set the precedence of storage. Hans Blix, former head of the International Atomic energy Agency and current President of the UAE’S International Advisory Council, noted: “it is still an open question of a draft final disposal and greater attention should be spent on deciding what to do.”

  • Some very low level nuclear waste can go into landfill-type settings. But low level waste consists of low concentrations of long-lived radionuclides and higher concentrations of these short-lived must remain sequestered for a few hundred years in subsurface engineering facilities. Medium-and high-level wastes require placing hundreds of meters below the ground for hundreds of thousands of years in order to ensure public safety. Intermediate waste containing high concentrations of long-lived radionuclides, as high-level waste, including spent fuel reprocessing and fuel waste. Because they are extremely radioactive high level waste that emits heat. There is no repository for high level nuclear waste disposal wherever in the world.
  • All types of energy production, money is on the front end of the process and of waste management in the back end. Macfarlane argues, however, that a failure to plan for the disposal of waste can cause the most profitable front end of a company to collapse.
  • Nuclear fuel discharged from a light water reactor after about four to six years in the kernel. This should be cool, because the fuel is radioactively and thermally very hot to discharge, in a pool. Actively cooled with borated water circulated, spent fuel pools are approximately 40 feet (12 meters) deep. Water not only removes heat, but also helps to absorb neutrons and stop a chain reaction. In some countries, including the United States, metal shelves in spent fuel pools hold four times the originally planned amount of fuel. The plans to reprocess fuel have failed for both economic and political reasons. This means that today is more fuel pools from reactor cores, and the fuel endangers big radiation in the event of an accident-loss of coolant, as happened in Fukushima.
  • Japan’s Fukushima Daiichi plant spent fuel has seven pools, one at each reactor and large shared swimming pool, dry storage of spent fuel on site. Initially, Japan had planned a brief period of storage of spent fuel in the reactor before reprocessing, but Japan’s reprocessing facility has suffered long delays (scheduled to open in 2007, the installation is not yet ready). This caused the spent fuel to build the reactor factory sites.
  • Countries should include additional spent fuel storage nuclear projects from the beginning, and not the creation of ad hoc solutions, after spent nuclear fuel has already begun to build. Storage location is a technical issue, but also a social and political.

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

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

Stick to rules on importing blended waste [08Oct11] - 0 views

  • nergySolutions is once again asking for the State of Utah’s permission to accept another vagrant bunch of radioactive waste. It plans to blend, or dilute, Class B and Class C waste with less radioactive waste until it just meets the Class A waste levels its license allows at its Clive disposal site. Think of it as kind of a radioactive smoothie.
  • This blended waste is a unique waste stream: something unforeseen and unknown to the Nuclear Regulatory Commission (NRC) when it developed its low-level waste regulations in 1981. While the commission is currently trying to develop coherent new guidance on this, its rules state that it is only OK to intentionally mix wastes “as long as the classification is not altered.” Utah does not have such a regulation.
  • At present there are no disposal sites that accept Classes B and C low level waste, but that will change in about a month when a Texas disposal site opens and starts accepting these materials, without any of the hazards incurred in actually putting these things in the blender. The public understands how corporations often use regulatory loopholes to their own benefit.

  • EnergySolutions is also partnering with a company (Studsvik) that in presentations to our board last year vigorously lobbied against blending, saying that there were “not sufficient safeguards,” in place, and that this “does not solve the problem.” And, what will be the actual increase of the total radioactive dose at the site, since the blended material will be manipulated to be at the very highest level of Class A waste?

Disposal of quake debris- Burning of 1 Billion Pounds- begins [05Nov11] - 0 views

  • Work to dispose of debris from the quake-ravaged city of Miyako, Iwate Prefecture, began Thursday in Tokyo with about 30 tons arriving on a train at Tokyo Freight Terminal, the first load from Iwate to be accepted by a local government outside the Tohoku region.
  • The Tokyo Metropolitan Government plans to accept a total of 11,000 tons of debris from Miyako by next March, as part of plans to dispose of a combined 500,000 tons of debris from both Iwate and Miyagi prefectures, the areas hit hardest by the March 11 earthquake and tsunami, by fiscal 2013. At the terminal in Shinagawa Ward, debris containers were transshipped onto trucks to be carried to a crushing facility in Ota Ward, from where combustibles will be taken to an incinerator in Koto Ward.
  • Resulting ash and incombustibles are to be used as landfill in Tokyo Bay. In light of radiation fears among residents, the metropolitan government plans to monitor and release data weekly on radiation levels in the air at the edge of the crushing premises and once a month on crushed waste, ash and exhaust gas, it said. Its four crushing facilities, incinerator and landfill site are all located in an industrial zone facing Tokyo Bay.

Avoiding Fracking Earthquakes May Prove Expensive: Scientific American - 0 views

  • With mounting evidence linking hundreds of small earthquakes from Oklahoma to Ohio to the energy industry's growing use of fracking technology, scientists say there is one way to minimize risks of even minor temblors. Only, it costs about $10 million a pop.
  • A thorough seismic survey to assess tracts of rock below where oil and gas drilling fluid is disposed of could help detect quake prone areas.
  • The more expensive method will be a hard sell as long as irrefutable proof of the link between fracking and earthquakes remains elusive. "If we knew what was in the earth we could perfectly mitigate the risk of earthquakes," said Austin Holland, seismologist at the Oklahoma Geological Survey. "That is something that we don't have enough science to establish yet." A 4.0 New Year's Eve quake in Ohio prompted officials to shut down five wells used to dispose of fluid used in the hydraulic fracturing process. That comes less than a year after Arkansas declared a moratorium due to a surge in earthquakes as companies developed the Fayetteville Shale reserve.

Electric cars may not be so green after all, says British study [10Jun11] - 0 views

  • An electric car owner would have to drive at least 129,000km before producing a net saving in CO2. Many electric cars will not travel that far in their lifetime because they typically have a range of less than 145km on a single charge and are unsuitable for long trips. Even those driven 160,000km would save only about a tonne of CO2 over their lifetimes.
  • The British study, which is the first analysis of the full lifetime emissions of electric cars covering manufacturing, driving and disposal, undermines the case for tackling climate change by the rapid introduction of electric cars.
  • The Committee on Climate Change, the UK government watchdog, has called for the number of electric cars on Britain's roads to increase from a few hundred now to 1.7 million by 2020.
  • ...2 more annotations...
  • The study was commissioned by the Low Carbon Vehicle Partnership, which is jointly funded by the British government and the car industry. It found that a mid-size electric car would produce 23.1 tonnes of CO2 over its lifetime, compared with 24 tonnes for a similar petrol car. Emissions from manufacturing electric cars are at least 50 per cent higher because batteries are made from materials such as lithium, copper and refined silicon, which require much energy to be processed.
  • Many electric cars are expected to need a replacement battery after a few years. Once the emissions from producing the second battery are added in, the total CO2 from producing an electric car rises to 12.6 tonnes, compared with 5.6 tonnes for a petrol car. Disposal also produces double the emissions because of the energy consumed in recovering and recycling metals in the battery. The study also took into account carbon emitted to generate the grid electricity consumed.

In Sweden, A Tempered Approach To Nuclear Waste [28Jul11] - 0 views

  • At least two dozen countries around the globe get energy from nuclear power, yet not one has been able to pull off a permanent disposal site. Finding communities willing to live with such dangerous stuff has been a big sticking point. But in Sweden, two communities have stepped up, and are willing to take the country's waste. Like many countries, Sweden has had its share of political meltdowns over nuclear power. Protests stirred an uproar in the early 1980s when the Swedish nuclear industry simply decided where to begin testing for a possible geologic disposal site.
  • But today, instead of deflecting protesters, the nuclear industry shuttles visitors by the busloads for guided tours of facilities. More than 1,100 feet below the surface, exotic machinery and copper tubes wide enough to fit two men fill an underground cavern carved from crystalline bedrock. In this working lab in eastern Sweden, a private nuclear waste company tests methods for permanently storing used fuel. It plans to encase the fuel rods in copper capsules, then bury them 1,500 feet down in bedrock where it is supposed to sit for the next 100,000 years.
  • how did nuclear waste in Sweden go from a toxic topic to a field trip? People in the area said the industry needed to start over with things like public participation, a transparent, predictable process and trust. The industry took these lessons to heart. "We know that we have to meet people and communicate what we want to do, why we want to do it and how we will find a place for it," says Inger Nordholm, a spokeswoman for the Swedish Nuclear Fuel and Waste Management Company, or SKB.

  • Lilliemark says she learned a lot about the risks of not dealing with the used fuel. And it changed her thinking. "I can't just close my eyes and imagine that the fuel is not here, because it is," she says.
  • Oskarshamn was one of two communities in eastern Sweden that stepped forward after nuclear waste officials asked for volunteers willing to let them start geologic testing. Charlotte Lilliemark, who lives about 12 miles north of the town, was just the kind of person a nuclear power executive would want to avoid. The former Stockholmer moved to the country to raise dressage horses and didn't want a waste dump anywhere near her
  • "I couldn't see anything that was positive," she says. But then local government officials asked her to lead a community advisory group. She says they told her: "We think you could contribute to the work — we need to open all the questions and be clear and transparent, and we want you to participate if you want to." And she did.
  • This spring, Swedish nuclear officials applied for a licensing application to build a geologic vault in the municipality of Osthammar, about a two-hour drive north of Stockholm. If they get it, the facility could open in 2025. "We believe that it will not create a stigma, but on the other hand create an interest in how to solve this very difficult issue that people in Japan and California and Germany must solve in one way or another," says Jacob Spangenberg, the mayor of Osthammar.
  • The community will see some financial benefits: Besides new jobs and infrastructure, Osthammar negotiated a deal with the company to receive approximately $80 million for long-term economic development if the repository is approved
  • Already the community gets money from a national waste fund to help it chart an independent course. It has retained technical consultants and hired five full-time employees. Spangenberg says Osthammar learned how to ask tough questions, press for conditions and also to keep cool.

Judge Puts Temporary Halt on Waste Control Specialists Expansion Decision [31Dec10] - 0 views

  • A Texas judge has temporarily halted plans for Waste Control Specialists WCS to begin allowing radioactive waste to be disposed at their facility. State District Judge Jon Wisser sided with environmentalists as he signed a temporary restraining order yesterday against the Texas Low-level Radioactive Waste Disposal Compact Commission. The injunction was issued in the judge's courtroom late Thursday morning, shortly after environmentalists filed the request, with nobody there representing the commission. A few minutes later, shocked lawyers from the Texas Attorney General's Office - which hadn't been officially notified of the pending court action - showed up and persuaded the judge to order a new hearing on the injunction.

Fracking Radiation Targeted By DOE, GE [03Aug11] - 0 views

  • The Department of Energy and General Electric will spend $2 million over the next two years to remove naturally occurring radioactive materials from the fracking fluids produced by America’s booming shale-gas industry. The New York State Department of Health has identified Radium-226 as a radionuclide of particular concern in the Marcellus Shale formation deep beneath the Appalachian Mountains. In hydraulic fracturing operations, drillers force water and a mixture of chemicals into wells to shatter the shale and free natural gas. The brine that returns to the surface has been found to contain up to 16,000 picoCuries per liter of radium-226 (pdf). The discharge limit in effluent for Radium 226 is 60 pCi/L, and the EPA’s drinking water standard is 5 pCi/L.
  • Uranium and Radon-222 have also been found in water returning to the surface from deep shale wells. In Pennsylvania, produced water has been discharged into streams and rivers from the state’s 71,000 wells after conventional wastewater treatment but without radiation testing, according to the Pittsburgh Post-Gazette and The New York Times, which drew attention to the radioactive contamination earlier this year after studying internal EPA documents: The documents reveal that the wastewater, which is sometimes hauled to sewage plants not designed to treat it and then discharged into rivers that supply drinking water, contains radioactivity at levels higher than previously known, and far higher than the level that federal regulators say is safe for these treatment plants to handle. via The New York Times
  • GE’s Global Research lab in Niskayuna, NY has proposed removing radioactive elements from produced waters and brine using a membrane distillation system similar to conventional reverse osmosis, but designed specifically to capture these radioactive materials. GE will spend $400,000 on the project and DOE will supply $1.6 million. The Energy Department announced the project Monday. The process will produce concentrated radioactive waste, which will be disposed of through conventional means, which usually means storage in sealed containers for deep geological disposal. The government is seeking to address environmental concerns without stemming a boom in cheap gas unleashed by hydraulic fracturing, or fracking, in shale formations.

Tests find excessive cesium at incinerators [15Sep11] - 0 views

  • Dust and ashes containing cesium beyond the legal limit of 8,000 becquerels per kilogram has been found at six industrial waste incinerators in Iwate, Fukushima and Chiba prefectures, the Environment Ministry said Thursday.
  • Samples from 110 industrial waste disposal facilities in 16 prefectures from east to northeast Japan have revealed cesium readings ranging from 10,800 to 144,200 becquerels at four incinerators in Fukushima Prefecture, 23,000 becquerels at a facility in Iwate Prefecture and 11,500 becquerels at an incinerator in Chiba Prefecture, the ministry said. Similar tests in late August found that ashes from nonindustrial incinerators contained more than 8,000 becquerels of cesium per kilogram in Tokyo and six other prefectures. A worker exposed to 8,000 becquerels of cesium a day for some amount of time would still come in below the annual radiation limit of 1 millisievert. At the end of August, the ministry issued a guideline advising local authorities to solidify incinerated dust and ashes containing between 8,000 to 100,000 becquerels of cesium per kilogram with cement, wrap it in watertight sheeting and bury it in landfills. The ministry earlier decided to allow waste containing up to 8,000 becquerels per kilogram to be buried in waste disposal sites, provided that no residences are built at the sites in the future.

The government has urged people within a 30-km radius of the plant to leave, but it's not mandatory. Some people say the evacuation zone should include Fukushima City, which is 63 km away from the plant. At the moment, the roughly 100,000 local children are kept indoors, schools have banned soccer and outdoor sports, pools were closed this summer, and building windows are generally kept closed. A handful of people argue the government should evacuate all of Fukushima prefecture, which has a population of about 2 million.  Sawada dedicated his career to studying the impact radiation has on human health, particularly among the survivors of Japan’s atomic bombings.

UAE weighs options for nuclear waste disposal [30May11] - 0 views

  • The UAE is weighing options for the long-term storage of nuclear waste from the country's proposed US$20 billion (Dh73.45bn) nuclear power plant.
  • One option under discussion is an underground cave to be shared with other nations from the region that could hold radioactive uranium and plutonium for thousands of years.
  • The UAE has not yet held formal talks with other Gulf nations on investing in a shared storage site, but there could be room for negotiation ahead as Saudi Arabia, Qatar and Kuwait lay the groundwork for their own civil nuclear programmes.

  • Such a site could not be hosted in the Emirates because of a law preventing the storage of nuclear waste from other nations. But it would be in the UAE's interest to ensure its neighbours, should they formally embark on civil nuclear programmes, have long-term storage options, said Dr Charles McCombie, the executive director of Arius. He estimated that a shared repository would cost more than €4 billion (Dh21.03bn) but would offer a large payback in the form of regional security.

  • The government must establish long-term plans for a new generation of nuclear power plants so future generations are not left dealing with its legacy, experts urged on Thursday.Ministers must work with the industry to create a "holistic" strategy which deals effectively with reprocessing and disposal of spent nuclear fuel and does not treat it simply as "an afterthought", they warned.The new build programme must also take into account the UK's stockpile of civil plutonium - the largest in the world - created as a waste fuel from nuclear reactors but which can potentially be reprocessed into new nuclear fuel.
  • The warning comes as the government pushes ahead with a new generation of nuclear power stations in a bid to meet electricity demand and cut carbon emissions from the energy sector.In a report from the Royal Society, the group of experts said the handling of nuclear fuel throughout its working cycle must be considered to reduce security risks and the danger of proliferation of nuclear weapons.Research and development programmes are needed from the outset of the new build project to ensure fuel is managed properly, they added.Roger Cashmore, chairman of the Royal Society working group and head of the UK Atomic Energy Authority, said: "The last time any UK government articulated a coherent long-term plan for nuclear power was in 1955.
  • "We need to ensure that government and industry work together now to develop a long-term, holistic strategy for nuclear power in the UK."This must encompass the entire nuclear fuel cycle, from fresh fuel manufacture to disposal. Indeed, spent fuel can no longer be an afterthought and governments worldwide need to face up to this issue."He added: "While the government has made some positive moves towards an integrated approach to nuclear power, more must be done."The call comes after the energy secretary, Chris Huhne, signalled that a new generation of nuclear power plants would go ahead after a government-ordered review into the Fukushima disaster in Japan found no reason to curtail the use of reactors in the UK.

  • The review by chief nuclear inspector Mike Weightman examined the lessons that could be learned from the crisis at the Fukushima reactor when it was hit by a magnitude nine earthquake and subsequent tsunami in March.It revealed no "fundamental weaknesses" in the regulatory or safety assessment regimes of the UK nuclear industry, although it did outline 38 areas where improvements could be made.Prof Cashmore added: "Fukushima has shown that we cannot be complacent about the safety of nuclear power."However, the same principle must apply to nuclear security and non-proliferation. Both governments and the nuclear industry need to seriously reassess their responsibilities in these areas."
