Finland’s nuclear regulator demands safety check for Olkiluoto 3 nuclear reactor’s pressure vessel

Nuclear watchdog seeks re-check of Olkiluoto 3 reactor yle 18 Apr 15 The Finnish Radiation and Nuclear Safety Authority (STUK) is demanding that energy utility TVO carry out new tests of the durability of the pressure vessel planned for the Olkiluoto 3 nuclear reactor. This follows a recent discovery by French officials of inconsistencies in the mechanical toughness of a vessel made for a similar reactor, also being built by the French company Areva.

The third unit for the Flamanville, France reactor was built by Areva in France, while the one to be used in the Finnish reactor has been assembled in Japan. Both units are of the European Pressurised Reactor (EPR) type.

“There are inconsistencies in the material that the reactor vessel is made of,” Tapani Virolainen, Deputy Director of STUK’s Nuclear Reactor Regulation Department, confirmed to Yle…….Virolainen explains that anomalies were found in both the reactor vessel head and reactor vessel bottom head. He says STUK will ask TVO to re-check the reactor vessel’s manufacturing process…….http://yle.fi/uutiset/nuclear_watchdog_seeks_re-check_of_olkiluoto_3_reactor/7937448

Tritium is a major radioactive pollutant from Canada’s CANDU nuclear power reactors.

safety-symbol-Smhighly-recommendedTritium Traffic: Deadly Dividends for Nuclear Industry, Peace Magazine By David H MartinIn February, 1934, the British journal, New Scientist, published an article by Tom Wilkie, “Old Age Can Kill the Bomb.” It was an ingenious solution to the arms control nightmare of verification; controlling not only the number of weapons, but the strategic materials that fuel them — mainly plutonium, enriched uranium and tritium. Wilkie focused on tritium, because it turns into non-radioactive helium at a rate of 5.5 per cent per year. A halt of tritium production would rapidly cripple all nuclear arsenals. Thus, attention was rivetted on Ontario Hydro’s plan to produce about 57 kilograms of tritium by 2006. A one megaton thermonuclear warhead (equivalent to one million tons of TN”) may contain as little as one gram of tritium.

Tritium (H3) (a form of hydrogen that emits beta radiation), is a major radioactive pollutant from Canada’s CANDU nuclear power reactors. Unlike American reactor systems, the CANDU uses heavy water as a moderator and coolant. The moderator and the heavy water coolant slows down the neutron release from the uranium fuel in the reactor so that a chain reaction can take place. The active ingredient in heavy water is deuterium, another form of hydrogen. When the deuterium picks up a neutron, some of it is transformed into tritium. The concentration of tritium in the heavy water increases with the age of the reactor.

The CANDU reactor system produces 2400 times as much tritium as the American light water reactor. Continue reading

Why China should avoid the doubtful dream of commercial nuclear reprocessing

Nuclear-marketing-continuesflag-ChinaReprocessing in China: A long, risky journey, Bulletin of the Atomic Scientists, April 15  Hui Zhang“………Should China continue pursuing its plans for fast breeder reactors and commercialized reprocessing? Good reasons exist for avoiding this course of action. First, because most of China’s power reactors are newly built, Beijing will face little pressure over the next two decades to reduce its spent fuel burden. And spent fuel can be stored safely, at low cost, in dry casks—or disposed of safely in a deep geological repository.

Second, China faces no shortage of uranium resources for the foreseeable future. The nation’s identified resources more than tripled between 2003 and 2012, to 265,500 metric tons from 77,000 metric tons. China’s potential uranium reserves amount to more than 2 million tons. Beijing in recent times has also secured huge overseas uranium resources—about three times as large as its own identified uranium reserves. More such reserves could easily be added.

In any event, the cost of uranium accounts for only a small percentage of the cost of power that reactors generate. Simply put, the cost of uranium will not increase in the foreseeable future to levels that would justify the cost of reprocessing and breeder reactors. To the extent that China is concerned about potential disruptions in its uranium supply, it could easily and inexpensively establish a “strategic” uranium stockpile.

China should carefully examine the experiences of nations that have launched large reprocessing programs and built demonstration breeder reactors in the expectation that the commercialization of these reactors would follow. Commercialization did not follow in those countries—but huge expenses were incurred for cleaning up reprocessing sites and disposing of separated plutonium. For China, there is no urgent need to go down this risky road.

Plutonium recycling is much more expensive, and much less safe and secure, than operating light water reactors with a once-through fuel cycle. As for nuclear waste, dry cask storage is a safe, flexible, and low-cost option that can postpone for decades the need either to reprocess spent fuel or to dispose of it directly—allowing time for technology to develop. China has no convincing rationale for rushing to build commercial-scale reprocessing facilities or plutonium breeder reactors. http://thebulletin.org/reprocessing-poised-growth-or-deaths-door8185

Nuclear reprocessing has NOT gone according to plan, in China

Nuclear-marketing-continuesReprocessing in China: A long, risky journey, Bulletin of the Atomic Scientists,  Hui Zhang , April 15  Since 1983, a closed fuel cycle has been an official element of China’s nuclear energy policy. According to proponents, plutonium reprocessing and breeder reactors will allow full utilization of China’s uranium resources, drastically reduce the volume of radioactive waste that must be stored in an underground repository, and establish a way to dispense with the spent fuel accumulating in China’s reactor pools.

But Beijing’s attempts to develop commercially viable reprocessing facilities and breeder reactors have been afflicted with technological difficulties, serious delays, and cost overruns. At this point—especially taking into account China’s ample uranium resources and its easy access to additional resources abroad—it appears very doubtful that reprocessing and fast reactors are the proper way forward for China’s nuclear energy sector.

Not according to plan………..

highly-recommendedflag-ChinaParallel with development of the pilot reprocessing plant, China has been working to establish commercially viable plutonium breeder reactors. According to a plan in place until 2013, development of breeder reactors was to be a three-stage process. The first stage was to complete a project known as the China Experimental Fast Reactor. The second stage would involve building, by about 2020, a few demonstration fast reactors. Finally, commercialized fast reactors would be deployed around 2030. Progress always ran far behind schedule.

The China Experimental Fast Reactor is a sodium-cooled experimental fast reactor using technology developed for Russia’s BN-600 reactor. The project, with a planned capacity of 20 megawatts, was approved in 1995. Construction began in 2000. As with the pilot reprocessing plant, the experimental fast reactor encountered many difficulties during construction. Capital cost estimates had to adjusted twice, with each estimate double the previous one. The reactor went critical in July 2010 and, by July 2011, 40 percent of its full power was incorporated into the grid. The reactor, however, was online for only 26 hours during the remainder of 2011, and it produced the equivalent of just one full power-hour. Not until December 2014 did the reactor manage to operate at full capacity for 72 hours. So 19 years passed between project approval and operation at full capacity.

As for the second stage of the pre-2013 plan, CNNC in 2009 signed an agreement with Russia’s Rosatom to jointly construct two copies of Russia’s BN-800 fast neutron reactor in China. But Beijing has not officially approved the project. As with the French reprocessing plant, Chinese experts complain that Russia is demanding too high a price. It is not clear when or if the project will go forward. Instead, CNNC in 2013 began focusing on the development of the indigenous 600-megawatt China Fast Reactor (CFR-600). The start of construction is envisioned for 2017, with operations to commence in 2023—but the government has not approved the project yet.

Experts from CNNC have also, since 2013, urged the development of China’s first commercial fast reactor—a 1,000-megawatt reactor based on experience gained from the CFR-600. But CNNC expert Gu Zhongmao—an advocate of the closed fuel cycle—said at a recent workshop on nuclear energy in East Asia that “China needs at least another 20 to 30 years of effort before commercialization of fast reactor energy systems, and there are so many uncertainties ahead. It is beyond our ability to draw a clear picture 20 years ahead.”…………. http://thebulletin.org/reprocessing-poised-growth-or-deaths-door8185

Recycling of nuclear fuel is more expensive than dry cask storage of nuclear wastes

text-relevantThe High and Hidden Costs of Nuclear Power  POLICY August & September 2010, No. 162 Review By Henry Sokolski…….Discouraging the use of government financial incentives to promote commercial nuclear power. This recommendation was made by the Congressional Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism. It would clearly include discouraging new, additional federal loan guarantees for nuclear fuel or power plant construction of the type now being proposed by President Obama and the nuclear industry. ………
Today, the lowest cost interim solution to storing spent fuel (good for 50 to several hundred years) is dry cask storage, above ground, at reactor sites. Recycling spent fuel, on the other hand, is not only more expensive, but runs much greater proliferation, terrorism, and nuclear theft risks.
 For these reasons, President Bush in 2004, the iaea in 2005, and the bipartisan U.S. Congressional Commission on the Prevention of Weapons of Mass Destruction Proliferation and Terrorism in 2008 all called for the imposition of a moratorium on commercial reprocessing. This reflects economic common sense. Unfortunately, in many countries, full employment, development of nuclear weapons options, and other political or military concerns often override straightforward cost-benefit analysis.
In the U.S., this tendency can be avoided by having the nuclear utilities themselves assume a significant portion of the costs of nuclear waste management and reactor site decommissioning. This would require changing the law in the U.S., which stipulates that all of the costs of final spent fuel storage are to be paid for by off-budget federal user fees. …….http://www.psr.org/nuclear-bailout/resources/the-high-and-hidden-costs-of.pdf

St George city decides against getting electricity from NuScale’s Small Modular Nuclear Reactors

text-SMRsCity opts to withdraw from nuclear power project, keep options open, St George News by  March 27, 2015 ST. GEORGE – City officials discussed the city’s future power generations needs during a City Council meeting Thursday. The city wants to keep its options open as far as those needs are concerned, and for the time being, is backing away from an experimental nuclear power option.

City staff recommended that the City Council hold off on committing to a project by NuScale Power. Based out of Oregon, NuScale proposes to build compact nuclear reactors that would be housed in a power plant built near Idaho Falls, Idaho. The compact reactors are designed to produce 40-50 megawatts of power.

A permit application for the proposed project is slated to be sent into the U.S. Nuclear Regulatory Commission for review, and could take until 2018 or longer to be approved. If approved, the power plant could be built and operational by 2024…….

Though St. George is one of UAMPS biggest utilities, city staff have recommended against committing to any binding agreements, saying they want the city to maintain flexibility over where it gets its power. The cost of being involved could run into the millions of dollars, said Laurie Mangum, the city’s energy services director……

Other sources of potential energy the city could tap into in the future include solar power or hydroelectric power generated along the Lake Powell Pipeline. Also, through its existing contracts and city-owned power-generation facilities, the city has 70 percent of its base load power needs covered up to around 2024-25, Esplin said.

“We’re in pretty good shape for the next eight-nine years,” Esplin said…….https://www.stgeorgeutah.com/news/archive/2015/03/27/mgk-city-opts-withdraw-nuclear-power-project-keep-options-open/#.VRXGyvyUcnk

Dubious USA Bills – Small Nuclear Reactors, “education on nuclear”, nuclear as “renewable”

Flag-USANuclear power measures face questions   CrossCut WEDNESDAY 25, MARCH 2015  by  The big topic at the House Technology & Economic Development Committee hearing was whether Washington should find a place to build small modular reactors, which would be produced for utility customers. Sen. Sharon Brown, R-Kennewick, is sponsoring this proposal and the two other nuclear-related bills that the committee examined. The Senate passed the SMRs-miragesmall modular reactor bill 27-21, mostly along party lines.Tri-Cities leaders envision a Boeing-style assembly plant to build small modular reactors. This is a long-range plan and is predicted to take several years to develop……

The concept is still on the drawing board. No one has built a commercial small modular reactor yet……

At the hearing, critics cited the lack of any track record on cost or safety for small modular reactors, plus concerns over the nation’s lack of a permanent place to store used nuclear fuel.

“Small nuclear reactors are still in the prototype stage. … The prototype has never been tested in power production yet,” said Thomas Buchanan of Physicians for Social Responsibility.

“I don’t think that the Department of Commerce should work on this until it has a design that passes the NRC,” said Chuck Johnson of the same organization.

Johnson argued that a single small-modular reactor would not generate enough electricity to efficiently recover its construction and operating costs…..

Deborah Wolpoff of Olympia pointed to the cancelation of the nation’s proposed nuclear fuel repository inside Yucca Mountain, with no replacement lined up. “I think it is irresponsible to promote this technology that produces this waste that we have no solution for,” Wolpoff said.

Committee member Rep. Gael Tarleton, D-Seattle, wondered why the Legislature should support a new nuclear industry while Hanford’s Cold War nuclear wastes are decades from being cleaned up….

nuclear-teacherAnother Brown bill, which the Senate passed 44-5, would create an education program aimed at providing nuclear science lessons to students in the eighth through 12th grades. Qualified American Nuclear Society members would be brought in for classroom sessions. Also, science teachers would receive instruction on nuclear science in order to teach the subject in the classrooms…….

Mary Hanson of Physicians Social Responsibility argued that the bill would give the nuclear industry influence over students, while other energy industries would not have the same access. She said American Nuclear Society members might be less versed in nuclear power’s health issues than its technical ones.

 

The third Brown bill, which the Senate passed 29-20, would add nuclear power to the list of alternative power sources that certain utilities can use to meet a state requirement to offer their customers voluntary participation in alternative energy purchases. The current list of green sources includes wind, solar, geothermal and biomass energy….

Physicians for Social Responsibility opposed it, contending nuclear energy is not a renewable power source….

President Obama quietly “greenwashes” Small Modular Nuclear Reactors

SMR developers have already looked to the federal government as one of their most important potential customers.text-SMRs

SMRs face major challenges before they can ever be deployed, including an apparent lack of private sector interest and the potential for unforeseen problems and cost overruns when building a factory to mass produce the technology

The failure to find investors caused two NuScale competitors, Generation mPower and Westinghouse Electric Co. LLC, to cut back on their SMR programs.

nuke-greenwashObama executive order tags small modular reactors as clean energy https://www.snl.com/Interactivex/article.aspx?CdId=A-31794585-10540 By Matthew Bandyk 26 Mar 15 A new executive order issued by President Barack Obama to cut greenhouse gas emissions from federal government agencies could benefit what has become a pet project of the administration: small modular reactors. The in-development technology is the only form of nuclear energy to qualify as clean energy under the order.

The order, announced March 19, requires federal agencies to ensure that increasing amounts of the electric and thermal energy they consume come from low-carbon dioxide-emitting “alternative energy” sources. At least 10% of their energy must come from these sources starting in 2016, all the way up to 25% by 2025.

The definition of alternative energy in the order does not include “nuclear power” in general but specifically “small modular nuclear reactor technologies,” a term used to refer to a number of proposed designs for portable reactors typically under 300 MW, which are much smaller and potentially cheaper and easier to build than conventional nuclear reactors.

With the order, the Obama administration is pushing policies in support of small modular reactors, or SMRs, which are similar to proposals being contemplated at the state level. The Washington state senate, for example, recently passed a bill that would count SMRs among wind and solar as “qualified alternative energy resources” in the state’s voluntary alternative energy purchase program for utilities.

Nuclear terrorism danger would be magnified, if Japan reactivated nuclear reprocessing

fast-breeder-MonjuNuclear terrorism risks in Northeast Asia: Japan’s reactor restart and spent fuel Nautilus Peace and Security NAPS Net Special Report by Peter Hayes 23 March 2015 “…..Japan’s Post-Fukushima Choice

Due to Fukushima, Japan now must choose to go in one of two directions that are largely exclusive: either towards a reactor restart choice that leads to a minimalist phase-out of separated plutonium over time; or towards a maximalist reliance on separated plutonium over time in a closed fuel cycle………

Should Japan opt to start enough reactors to justify reactivating the plutonium fuel cycle, then the implications for nuclear terrorism would be substantial. The train of logic for maximum spent fuel arising from a closed nuclear fuel cycle is radically different to that for the once-through fuel cycle.  In this trajectory, the following would occur:

  • Japan starts many more light water reactors, sooner rather than later, and extends reactor lifetimes beyond forty years, and constructs new reactors
  • This choice enables far more MOx fuel fabrication and recycling of MOx fuel to these reactors than in the once-through fuel cycle usage; this choice would either slowly reduce or rapidly increase the stockpile of separated plutonium that would be supplemented (if the central state is willing to subsidize heavily the utilities for using MOx fuel) by reprocessing the spent fuel from the operation of the light water reactors
  • Thereby generating a new stream of separated and un-separated plutonium in Japan to store and secure, and available for diversion or attack.

Although it does not follow automatically, this vision of the revived closed fuel cycle also implies that:

  • The fast reactor is developed in order to burn actinides to reduce the waste disposal problem (whether it would do so is debatable)
  • The fast reactor would be developed to breed plutonium based on the argument that doing so makes Japan more independent from external nuclear fuel supply.

All the steps in this second path which maximizes separated fuel involves more transport, more bulk processing and storage, and creates more opportunity for non-state actors to divert fissile material or to attack directly the spent fuel stocks in pools or other nuclear materials process sites in the envisioned “closed” fuel cycle.    In short, this trajectory maximizes the nuclear terrorist threat, directly and indirectly, over the next thirty years, especially when the demonstration effect on other states to follow suit are taken into account.  For exactly this reason, the United States has reaffirmed recently that it does not favor MOx use and breeder activity in Japan or elsewhere……..[19]http://nautilus.org/napsnet/napsnet-special-reports/nuclear-terrorism-risks-in-northeast-asia-japans-reactor-restart-and-spent-fuel/

Fukushima company to build 400 unmanned surveillance aircraft

drone-1DRONES TO BE MASS-PRODUCED IN FUKUSHIMA http://fukushimaupdate.com/drones-to-be-mass-produced-in-fukushima/

FEBRUARY 22, 2015  via the-japan-news.com   The nation’s first mass production of drones will kick off this year at a plant near the crippled Fukushima No. 1 nuclear power plant, drone expert Kenzo Nonami and product prototype manufacturer Kikuchi Seisakusho Co. said Friday.

Kikuchi Seisakusho plans to produce 400 unmanned surveillance aircraft at its plant in Minamisoma in Fukushima Prefecture. “Fukushima is a suitable production site given its need to measure radiation,” said Nonami, a professor at Chiba University. “We also hope that production will help the region’s recovery.”

The drone, 50 centimeters in height and 90 centimeters in diameter, can fly for up to 30 minutes at a time at speeds of up to 36 kph. With six propellers, it weighs only about three kilograms but can carry loads of up to six kilograms. It will be priced at around ¥2 million to ¥3 million.

The drone made a demonstration flight Friday, taking photos from 20 meters above the ground. A larger drone currently under development, with the capacity to carry loads of up to 30 kilograms, was also shown.

The use of drones is expected to spread for tasks such as measuring radiation, shooting movies and monitoring social infrastructure such as bridges, as well as for work related to the decommissioning of reactors at the Fukushima No. 1 plant.

The United States is considering regulating the use of drones to protect privacy and ensure safety. A similar debate may also take place in Japan ahead of their full implementation.

Washington State Senator Sharon Brown enthusiastically pushing for Small Modular Nuclear Reactors

text-SMRsNuclear Advocate Pushes For Modular Reactor Presence In Washington State  http://www.icontact-archive.com/uY4CWN-9Ks3su6iHyVeY7nHzrprAq8_d?w=1 Feb 25 2015  A state senator in Washington, Sharon Brown, R-Kennewick, is promoting nuclear energy with a focus on technology that has yet to be put into operation.

Bills that Brown have sponsored nudge the state towards acceptance of modular, factory-built nuclear reactors, The Olympian reported Tuesday.

Brown has called for a relatively modest $176,000 study to identify sites for nuclear power reactors that are in frequent discussions, but have yet to be built – reactors with a generation capacity of 300 MW or less.

In neighboring Oregon, NuScale Power is developing reactors that will built in one location and shipped by truck or rail to their final destination

“We need to make sure we’re not left behind,” said Brown at a hearing Tuesday. She also said, “It’s really important that as a state we get our arms around small nuclear reactors.”

Brown, who is pushing the state to nudge the federal government on construction of a federal waste repository, has sponsored other nuclear power-friendly bills that cleared a critical deadline last week. These include a bill to provide sales tax relief for small reactor production and one that mandates the Commerce Department support small reactors development for commercial use.

She has also sponsored measures that would allow energy from modular reactors to count as part of the state’s renewable energy targets, although these initiatives have strong opposition from environment groups.

The initiatives follow up on a previous state study, completed in September, that said a modular reactor facility was feasible for the Hanford Site nuclear facility.
