Greenpeace exposes high radiation risks in Fukushima village as govt prepares to lift evacuation order http://www.newkerala.com/news/fullnews-228867.html Tokyo/ New Delhi, Feb 21 : The Japanese government will soon lift evacuation orders for 6,000 citizens of Iitate village in Fukushima prefecture where radiation levels in nearby forests are comparable to the current levels within the Chernobyl 30km exclusion zone – an area that more than 30 years after the accident remains formally closed to habitation.
Seventy-five percent of Iitate is contaminated forested mountains, a Greenpeace statement claimed..
A survey team led by Greenpeace Japan recently found radiation dose rates at houses in the village of Iitate well above long-term government targets, with annual and lifetime exposure levels posing a long-term risk to citizens who may return. Evacuation orders will be lifted for Iitate no later than March 31, 2017, to be followed one year later by the termination of compensation payments.
The relatively high radiation values, both inside and outside houses, show an unacceptable radiation risk for citizens if they were to return to Iitate. Citizens returning to their irradiated homes are at risk of receiving radiation equivalent to one chest X-ray every week. This is not normal or acceptable, said Ai Kashiwagi, energy campaigner with Greenpeace Japan .
As Japan nears the six year anniversary of the nuclear disaster, the Japanese government last week confirmed that it has not yet conducted any assessments of lifetime exposure risks for citizens if they were to return to Iitate.
Recent reports suggest that the cost of cleaning up of Fukushima plant would cost more than 12lakh crores. If a developed country like Japan, known for its processes and systems, is finding it too difficult to handle the disaster, it makes little sense for India to go ahead and sign up for four more reactors at Kudankulam and elsewhere. In the words of George Santania Those who cannot remember the past are condemned to repeat it, says G. Sundarrajan of Poovulagin Nanbargal.
Life can never go back to normal for people living near nuclear power plants. But clearly, the world has failed to learn its lessons from nuclear accidents like those in Chernobyl and Fukushima. India, for instance, seems determined to add on to its nuclear power capacity despite putting the lives of millions of people at risk, says Nandikesh Sivalingam, climate and energy campaigner, Greenpeace India.
The fact remains that nuclear power is neither safe nor economical, and that India is grossly ill-prepared to handle a nuclear disaster. This was pointed out by Red Alert, a Greenpeace India report that released last year.
Last years Indo-Japan nuclear deal also negated the lessons learnt from Fukushima.
The deal to buy six AP1000 reactors was more of a last ditch effort to save Westinghouse/Toshiba from imminent meltdown. Now, after the meltdown, the future of the six nuclear reactors has put a question mark on the economic viability of nuclear power. Its reported that the cost of building these six reactors will be three to six times greater than the cost of building a solar photovoltaic plant of the same capacity.
It should also be noted that India is currently in a situation of surplus power witnessing massive installed overcapacity in the electricity sector. With the solar tariffs going down to record low levels, Indias energy needs for the next ten years can be fulfilled by cleaner and safer sources of energy in the form of solar and wind.
Greenpeace India stand by the victims of Fukushima who are being forced to return to the accident site for economic reasons. India must learn from the Fukushima disaster and its long lasting impacts on peoples lives and livelihoods and move away permanently from highly risky and economically unviable nuclear energy to safer, greener and cheaper energy sources like solar and wind.
Greenpeace has launched a public petition in solidarity with the Fukushima survivors campaigning for the restitution/protection of their human rights.

Radiation levels at Fukushima reactor puzzle nuclear experts, THE ASAHI SHIMBUN, February 19, 2017 A robot was expected to solidify ways to clean up the No. 2 reactor at the Fukushima No. 1 nuclear plant, but its short-lived mission raised puzzling questions that could derail existing decommissioning plans.
The robot, Sasori, was abandoned in the melted-down reactor after it became stuck in deposits and other debris that are believed to have interfered with its drive system.
But it did take radiation measurements that indicate Tokyo Electric Power Co., operator of the plant, was too optimistic about the state and location of the melted fuel within the reactor. The melted fuel, in fact, may be spread out all over the reactor’s containment vessel.
Scientists had believed the melted nuclear fuel fell through the reactor’s pressure vessel and landed on metal grating and the floor of the containment vessel.
The results of Sasori’s investigation, coupled with previous data taken from possible images of the melted fuel, show the situation within the reactor is much worse than expected. And a fresh investigation into the reactor is now nowhere in sight.
A remote-controlled video camera inserted into the reactor on Jan. 30 took what are believed to be the first images of melted fuel at the plant, which suffered a triple meltdown after the March 2011 Great East Japan Earthquake and tsunami.
Based on the images, TEPCO estimated 530 sieverts per hour at a point almost halfway between the metal grating directly beneath the pressure vessel and the wall of the containment vessel. Black lumps on the grating are believed to be melted fuel.
A different robot sent in on Feb. 9 to take pictures and prepare for Sasori’s mission estimated 650 sieverts per hour near the same spot.
Both 530 and 650 sieverts per hour can kill a person within a minute.
Sasori, equipped with a dosimeter and two cameras, on Feb. 16 recorded a reading of 210 sieverts per hour near the same location, the highest figure measured with instruments in the aftermath of the disaster.
Sasori was supposed to travel along a rail connecting the outer wall of the containment vessel with the metal grating to measure radiation doses and shoot pictures inside, essential parts of work toward decommissioning the reactor.
After traveling only 2 meters, the robot became stuck before it could reach the metal grating.
TEPCO at a news conference repeatedly said that Sasori’s investigation was not a “failure” but had produced “meaningful” results.
However, an official close to TEPCO said, “I had great expectations for Sasori, so I was shocked by how it turned out.”……(This article was compiled from reports by Kohei Tomida, Masanobu Higashiyama and Takashi Sugimoto) http://www.asahi.com/ajw/articles/AJ201702190042.html

Toshiba’s woes weigh heavily on government’s ambition to sell Japan’s nuclear technology
OSAKA – Toshiba’s announcement that it will write down nearly ¥712.5 billion in losses involving its U.S. nuclear unit, Westinghouse, is seen as a major setback for the government’s strategy of selling Japanese nuclear power technology abroad.
Over the past four years, Prime Minister Shinzo Abe, the Ministry of Economy, Trade, and Industry, and nuclear power players, such as Toshiba/Westinghouse, General Electric-Hitachi and Mitsubishi Heavy Industries, have promoted Japanese nuclear reactor technology worldwide.
Attempts to increase exports came even as concern within Japan grew over nuclear safety following a triple meltdown at the Fukushima No. 1 plant in the wake of the March 11, 2011 earthquake and tsunami. The efforts also came as questions were being raised about the total cost of nuclear power compared with other energy sources.
Japanese firms have attempted, with little success, to sell their technologies in countries as diverse as France, Vietnam, India, Turkey, Hungary, Poland, Slovakia, the Czech Republic and the United Arab Emirates. In June 2016, Toshiba said its goal was to win orders for 45 or more nuclear reactors overseas by 2030.
But Tuesday’s announcement by Toshiba came a few weeks after the company announced it would not take any new construction orders for nuclear reactors, and that it would focus instead on maintenance and decommissioning operations.
That decision effectively ended a decade-long effort by Toshiba, which began when it acquired a majority stake in Westinghouse in 2006, to make nuclear reactors a viable export business.
It follows greater than projected construction costs for four Westinghouse AP1000 next-generation nuclear reactors in the U.S. that have run billions of dollars over budget and are three years behind schedule. Original plans called for their startup around 2019 but that could be delayed.
Yoshimitsu Kobayashi, chairman of the Japan Association of Corporate Executives, told reporters at a regular news conference on Tuesday that promoting nuclear reactor exports was a necessary strategy, but one that needed to be reviewed.
“The nuclear power industry requires huge amounts of money for safety,” Kobayashi said.
“Given such high costs, we have to think about whether just one company can succeed. We have to keep strong technology in Japan, but we need to rethink how to create a union of private firms” in the nuclear business, he said.
But with Toshiba’s problems and the growing use worldwide of other, cheaper energy sources, including some renewables, anti-nuclear groups see an opportunity for Japan to change its basic policy.
“The Japanese government’s nuclear export policy was built on a combination of a poor understanding of the global energy market and self-delusion, said Shaun Burnie, a senior nuclear specialist at Greenpeace Germany who is currently based in Japan.
“The sooner the government and industry realize there is no future for nuclear power either domestically or in exports, the sooner they can concentrate on the energy technology of the future — renewables.”

VOX POPULI: Toshiba’s plight shows nuclear business is now a treacherous bet
What appears to be a lump of melted nuclear fuel is discernible in a photo, released late last month, of the interior of the crippled No. 2 reactor at the Fukushima No. 1 nuclear power plant.
The high radiation level inside the reactor would be lethal to humans so a small robot was expected to start inspecting the interior on Feb. 16. (The robot started inspection around 7:50 a.m.)
The robot is marked with the name TOSHIBA.
While leading the nation in the dismantling of nuclear reactors, Toshiba Corp. has aggressively pursued nuclear power plant construction overseas through its U.S. affiliate.
But on Feb. 14, the company announced a projected loss of 712.5 billion yen ($6.3 billion) in its nuclear business. To survive, Toshiba will have to sell off its profitable businesses piecemeal. To be sure, the company is in for massive restructuring.
The 2011 nuclear accident at the Fukushima plant was one of the indirect causes of Toshiba’s losses. Around the world, tighter regulations have been applied to nuclear power plants because of safety concerns, and Toshiba’s four nuclear plant construction projects in the United States became far more costly than anticipated.
The company has only itself to blame for underestimating the consequences of the Fukushima disaster.
I dropped in at the Toshiba Science Museum in Kawasaki, Kanagawa Prefecture, the other day. Its impressive array of exhibits included Japan’s first electric refrigerator, washing machine and vacuum cleaner. There was even a portable personal computer, said to be the first of its kind in the world.
Once a prestigious corporation that boasted cutting-edge technology, I wonder how long Toshiba’s decline will continue.
Overseas, Siemens AG of Germany withdrew from the nuclear business after the Fukushima accident, and France’s Areva SA is said to be struggling.
Toshiba’s massive losses remind us anew that the end is drawing near on the era of lucrative nuclear businesses.
A long, tough road lies ahead for the decommissioning of Fukushima’s nuclear reactors. I feel for Toshiba workers who are engaged in this task while their company languishes.
It will soon be six years since the Fukushima disaster. The days of having to confront the gravity of that accident are far from over.

TEPCO admits error in screening report
Japan’s Nuclear Regulation Authority is demanding an explanation from Tokyo Electric Power Company.
TEPCO has admitted to submitting inaccurate information from calculations 3 years ago on plans for restarting two of its nuclear reactors in Niigata Prefecture.
The regulator is in the final stages of screening the No.6 and 7 reactors at TEPCO’s Kashiwazaki-Kariwa plant.
The reactors must meet new government requirements introduced after the 2011 Fukushima disaster.
Regulators gathered on Tuesday for discussions with TEPCO about buildings at the plant to be used as headquarters in an emergency.
TEPCO officials admitted one of the buildings lacked the necessary quake-resistance in all 7 of the company’s tests.
They had earlier said that the building had failed 5 of the 7 tests. They said they would not use the building.
They blamed the discrepancy on a failure by the civil engineering department to convey test results to the equipment design department.
The regulators noted the lack of coordination between TEPCO departments on the impact of soil liquefaction on breakwaters.
They called the mistakes unacceptable, and they’re demanding that TEPCO provide details and countermeasures.

Key Niigata nuclear plant building may not be quake-proof
Tokyo Electric Power Co. has revealed that a key building at its Kashiwazaki-Kariwa nuclear power plant may not be able to withstand even half of the assumed strongest seismic shaking, contrary to its earlier assurances.
TEPCO’s disclosure came Feb. 14 during a screening by the Nuclear Regulation Authority (NRA) for the restart of the No. 6 and No. 7 reactors at the nuclear power plant in Niigata Prefecture, which is the world’s largest.
The utility became aware of the possibility in 2014, but the information was not shared within the company. TEPCO reported to the NRA that the building can withstand temblors of 7, the highest category on the Japanese seismic intensity scale.
The building is designed to serve as an on-site emergency headquarters in the event of a severe accident, such as one caused by an earthquake.
An earthquake that occurred off the Chuetsu region of Niigata Prefecture in 2007 badly damaged the Kashiwazaki-Kariwa plant.
In response, TEPCO constructed the building in question in 2009. At that time, it said the structure could withstand the assumed biggest earthquake motions that are 1.5 times stronger than those described in the Building Standards Law.
In 2014, the utility checked the building’s anti-quake capabilities again. It found that it may not be able to withstand horizontal movements triggered by even half the anticipated strongest earthquake, and that it could collapse into the side of an adjacent building.
That information was not conveyed to the company’s division in charge of the NRA’s screening, and thus escaped notice from NRA inspections.
Takafumi Anegawa, managing executive officer of TEPCO, apologized, saying, “We did not conceal the possibility. The in-house liaison was insufficient.”
An NRA official said, “Information is not shared in the company. Lessons from the accident at the Fukushima No. 1 nuclear power plant are not utilized.”

Visitors look at the logo of Tokyo Electric Power Co (TEPCO) at the Energy Market Liberalisation Expo in Tokyo, Japan March 2, 2016
Tokyo Electric Power Co (Tepco) submitted plans on Wednesday to sell a total of 70 billion yen ($612 million) of bonds, its first sale since the 2011 Fukushima nuclear disaster.
Tepco unit, Tepco Power Grid Inc, which is in charge of power transmission and distribution, said in a filing with the Kanto Local Finance Bureau it will sell a 30 billion yen three-year bond and a 40 billion yen five-year bond. The coupon will be set between March 3 and 17.
The sale will mark the return of the company to Japan’s corporate bond market, which it dominated before the 2011 earthquake and tsunami triggered the world’s worst nuclear crisis since Chernobyl in 1986, bringing Tepco to its knees.
The utility, once Asia’s largest, was essentially nationalized after Fukushima. It currently faces billions of dollars in costs to dismantle the crippled Fukushima-Daiichi nuclear power plant, decontaminate the area and compensate victims after the meltdown of three reactors.
Tepco, which has 650 billion yen worth of bonds maturing in the year ending March 2018, wants to restart regular bond issuance to ensure stable refinancing. It said the planned issue was to pay for “equipment, pay back debt and bond redemption.”
Investors, who were initially skeptical about the bond issuance plan, have become more comfortable with the utility’s outlook after the government last year provided more details on decommissioning and compensation costs.
The government owns 50.1 percent of the company following its bailout, seen by some investors as an implicit state guarantee for the company.
Six firms have been hired to manage the sale: SMBC Nikko Securities, a unit of Sumitomo Mitsui Financial Group; Nomura Securities; Mitsubishi UFJ Morgan Stanley Securities, a unit of Mitsubishi UFJ Financial Group Inc; Mizuho Securities, a unit of Mizuho Financial Group Inc; Daiwa Securities; and Shinkin Securities, a unit of Shinkin Central Bank.

Japan’s nuclear watchdog will ease quake-related and other regulations on storing spent fuel to push the use of dry casks and reduce the dangers stemming from power failures at nuclear power plants.
The Nuclear Regulation Authority decided on Jan. 25 that utilities should place spent nuclear fuel in the special air cooling containers instead of the common practice of submerging the fuel rods in pools of water.
Fuel stored in pools is cooled by circulating water with pumps, but the system can shut down if earthquakes and other disasters cut off the power supply. The water could then evaporate, leaving the spent fuel and radioactive substances exposed to air.
Electric power companies have shown a positive attitude toward the dry storage system because it would enable them to keep more spent fuel when the pools are filled close to capacity.
However, municipalities that host nuclear power plants have expressed strong concerns that the system will let utilities keep spent nuclear fuel at plant sites for prolonged periods.
NRA Chairman Shunichi Tanaka stressed the need for safety.
“It (dry cask storage) is much safer than storing fuel in pools,” he said.
The Great East Japan Earthquake and tsunami cut off power to Tokyo Electric Power Co.’s Fukushima No. 1 nuclear plant in March 2011. Three reactors melted down, and the cooling system would not work for more than 1,000 spent fuel assemblies in the pool in the No. 4 reactor building.
Fears arose that all water in the pool could evaporate. But emergency measures, including the pumping in of water, were taken to keep the fuel submerged.
Under the dry storage system, the fuel is sufficiently cooled in pools and placed in dedicated airtight cases. The special casks are then stored inside air-permeable facilities.
The NRA plans to promote use of casks that are currently used to transport spent nuclear fuel.
The containers have passed durability tests and can withstand falls from a height of 9 meters and high-temperature fires.
Dry storage containers are widely used in the United States and Europe.
But the use of dry casks has not spread in Japan because of the high hurdles that must be cleared. One requirement is that those containers must be stored in building that can withstand the strongest earthquake predicted in the area.
As a result, dry storage containers are used at only a few nuclear facilities in the country, such as Japan Atomic Power Co.’s Tokai No. 2 nuclear power plant in Ibaraki Prefecture.
According to the Federation of Electric Power Companies of Japan, a total of 15,000 tons of spent fuel is stored at 17 nuclear plants across Japan.
Seventy percent of their fuel pools and other storage facilities have been filled with spent fuel.

The government-backed Riken research institute is set to launch experiments on converting radioactive substances contained in high-level nuclear waste generated at atomic power stations into precious metals starting fiscal 2018, it has been learned.
The method, which is dubbed “modern alchemy,” is said to be theoretically viable but hasn’t been put into practical use. If realized, the formula is expected to contribute to trimming nuclear waste and even making effective use of it.
The experiment will be part of the Cabinet Office’s program to promote innovative research and development, called “Impulsing Paradigm Change through Disruptive Technologies (ImPACT)” program. In the initial stage of the demonstration experiment, palladium-107, a radioactive material contained in nuclear waste and whose half-life is 6.5 million years, will be turned into nontoxic palladium-106, which is commonly used in dental therapy, jewelry goods and exhaust gas purification catalysts.
Using an accelerator at the Riken Nishina Center for Accelerator-Based Science in Wako, Saitama Prefecture, the scientists will attempt to convert palladium-107 into palladium-106 by irradiating the former with deuteron beams, in what is called the “nuclear transformation” process. The experiment is set to be the world’s first of its kind on nuclear transformation of palladium, according to Riken officials.
The researchers will compile the outcome of the experiment as early as the fall of 2018 after confirming the ratio of palladium successfully transformed and other results.
As nuclear waste is highly radioactive, the government is currently looking into methods to isolate such waste deep into the ground after sealing it in specially designed containers. If the nuclear transformation process proves viable, it could contribute to reducing nuclear waste and making efficient use of it.
It remains to be seen whether nuclear transformation will prove successful just as in theory and if the process can be turned into practical use at a low cost. In the past, a nuclear transformation experiment was carried out on minor actinides, or “heavy” nuclear waste, at the Joyo experimental fast reactor in Oarai, Ibaraki Prefecture, but the upcoming experiment will be the country’s first using fission products, or “light” nuclear waste.
ImPACT program manager Reiko Fujita said, “We are still at the basic research stage and are far from putting it into practical use. We will, however, move a step forward if we manage to obtain data through our experiment.”

Radiation levels inside Fukushima too high for robot http://www.cbc.ca/news/technology/fukushima-nuclear-robot-radiation-1.3973908 , The robot was to inspect and clean a passage before another robot does a fuller examination The Associated Press Feb 09, 2017 A remote-controlled cleaning robot sent into a damaged reactor at Japan’s Fukushima nuclear plant had to be removed Thursday before it completed its work because of camera problems most likely caused by high radiation levels.
It was the first time a robot has entered the chamber inside the Unit 2 reactor since a March 2011 earthquake and tsunami critically damaged the Fukushima Da-ichi nuclear plant.
Tokyo Electric Power Co. (TEPCO) said it was trying to inspect and clean a passage before another robot does a fuller examination to assess damage to the structure and its fuel. The second robot, known as the “scorpion,” will also measure radiation and temperatures.
Thursday’s problem underscores the challenges in decommissioning the wrecked nuclear plant. Inadequate cleaning, high radiation and structural damage could limit subsequent probes, and may require more radiation-resistant cameras and other equipment, TEPCO spokesman Takahiro Kimoto said.
“We will further study (Thursday’s) outcome before deciding on the deployment of the scorpion,” he said.
TEPCO needs to know the melted fuel’s exact location and condition and other structural damage in each of the three wrecked reactors to figure out the best and safest ways to remove the fuel. It is part of the decommissioning work, which is expected to take decades.
During Thursday’s cleaning mission, the robot went only part way into a space under the core that TEPCO wants to inspect closely. It crawled down the passage while peeling debris with a scraper and using water spray to blow some debris away. The dark brown deposits grew thicker and harder to remove as the robot went further.
More obstacles for second mission
After about two hours, the two cameras on the robot suddenly developed a lot of noise and their images quickly darkened — a sign of a problem caused by high radiation. Operators of the robot pulled it out of the chamber before completely losing control of it.
The outcome means the second robot will encounter more obstacles and have less time than expected for examination on its mission, currently planned for later this month, though Thursday’s results may cause a delay.
Both of the robots are designed to withstand up to 1,000 Sieverts of radiation. The cleaner’s two-hour endurance roughly matches an estimated radiation of 650 Sieverts per hour based on noise analysis of the images transmitted by the robot-mounted cameras. That’s less than one-tenth of the radiation levels inside a running reactor, but still would kill a person almost instantly.
Kimoto said the noise-based radiation analysis of the Unit 2’s condition showed a spike in radioactivity along a connecting bridge used to slide control rods in and out, a sign of a nearby source of high radioactivity, while levels were much lower in areas underneath the core, the opposite of what would normally be the case. He said the results are puzzling and require further analysis.
TEPCO officials said that despite the dangerously high figures, radiation is not leaking outside of the reactor.
Images recently captured from inside the chamber showed damage and structures coated with molten material, possibly mixed with melted nuclear fuel, and part of a disc platform hanging below the core that had been melted through.

The Nuclear Regulation Authority (NRA) is set to require power companies and other operators to complete waterproofing measures of their nuclear facilities within the next year, following an incident in which tons of rainwater flowed into the No. 2 reactor building at the Shika nuclear plant last fall, it has been learned.
The NRA conducted a survey on nuclear plant operators across the country to detect possible similar problems and released the results on Feb. 8. The survey found that measures to shut off the influx of water into reactor buildings had not been carried out on at least 655 parts of such structures at 10 nuclear facilities.
The facilities mentioned in the survey are: the No. 1 and 2 reactors at the Shika nuclear plant in Ishikawa Prefecture, the No. 2 reactor at Tohoku Electric Power Co.’s Onagawa nuclear plant in Miyagi Prefecture, the No. 1 through 4 reactors at Tokyo Electric Power Co. (TEPCO)’s Fukushima No. 2 nuclear plant in Fukushima Prefecture, the No. 1 through 7 reactors at TEPCO’s Kashiwazaki-Kariwa nuclear plant in Niigata Prefecture, the No. 3 through 5 reactors at Chubu Electric Power Co.’s Hamaoka nuclear plant in Shizuoka Prefecture, the No. 1 and 2 reactors at Chugoku Electric Power Co.’s Shimane nuclear plant in Shimane Prefecture, the No. 1 reactor at the Japan Atomic Power Co.’s Tsuruga Power Station in Fukui Prefecture, the Monju prototype fast-breeder reactor also in Fukui Prefecture, the Tokai Reprocessing Plant in Ibaraki Prefecture and the Rokkasho Reprocessing Plant in Aomori Prefecture. The Shimane nuclear plant’s No. 1 reactor and the Tsuruga Power Station’s No. 1 reactor are under decommissioning work, while the Monju reactor and the Tokai Reprocessing Plant are set to be dismantled.
All the reactors in question are boiling-water reactors. Meanwhile, waterproofing measures have been completed on all of the country’s pressurized-water reactors — including the No. 1 and 2 reactors at Kyushu Electric Power Co.’s Sendai nuclear plant in Kagoshima Prefecture, which were reactivated amid much controversy.
Following heavy rainfall in late September last year, approximately 6.6 metric tons of rainwater flowed into the building housing the No. 2 reactor at the Shika nuclear plant by way of cracks and gaps around plumbing, causing short circuits in lighting switchboards. The crisis occurred as the amount of precipitation surpassed the capacity of makeshift drainage pumps, raising the risk that a storage battery for cooling the reactor in emergencies and other key safety equipment would become submerged and unusable.
The NRA’s new safety regulations introduced in the wake of the 2011 meltdowns at the Fukushima No. 1 nuclear plant call on power companies and other plant operators to take measures to prevent an influx of rainwater and tsunami in reactor buildings from affecting key facilities. However, the regulations do not oblige plant operators to take such measures as fill in the gaps in pipes that penetrate reactor buildings. In response to the recent incident at the Shika plant, which the NRA views seriously, the agency has decided to effectively mandate plant operators to implement waterproofing measures at all nuclear facilities.

Japan’s regulator says 10 of the country’s nuclear power plants and other facilities have yet to complete work to prevent massive inflows of rainwater into buildings in the event of torrential rain.
The Nuclear Regulation Authority has called on operators to finish the work within a year.
The NRA urged them to take the steps after rainwater got into the Shika nuclear plant in central Japan and short-circuited a distribution switchboard last September.
At a meeting on Wednesday, NRA officials said 10 plants and facilities have yet to finish waterproofing areas of buildings where pipes enter from the outside.
New regulations established after the 2011 Fukushima Daiichi accident require operators to protect plants’ power sources and reactor-cooling systems from inflows of rainwater and tsunami.
Some of the 10 plants and facilities are equipped with a drainage system for rainwater. But the regulator is urging the additional measures for greater safety.
Work has yet to be completed at: the Onagawa plant in Miyagi Prefecture, the Fukushima Daini plant in Fukushima Prefecture, the Kashiwazaki-Kariwa plant in Niigata Prefecture, the Hamaoka plant in Shizuoka Prefecture, the Shika plant in Ishikawa Prefecture, the Tsuruga plant in Fukui Prefecture and the Shimane plant in Shimane Prefecture.
Others are nuclear fuel reprocessing plants in Aomori and Ibaraki prefectures, and the Monju fast-breeder reactor in Fukui.
Officials say such measures are already in place at the restarted plants in Kagoshima and Ehime prefectures.

Toshiba’s Nuclear Projects Falling Like a Row of Dominos February 6, 2017, The Energy Collective by Dan Yurman The Japanese conglomerate is expected to announce Feb 14 that it will pull out of projects in the UK (3 AP1000s) and India (6 AP1000s) due to its deep financial difficulties.
Westinghouse may be sold off for its technology and services lines of business, but new investors will be needed for the projects in the UK and India.A sense of panic is emerging globally as Toshiba, troubled by extensive losses and fake financial reports, heads toward a complete exit from the commercial nuclear energy industry. The two countries that will be hardest hit by the expected actions will be the UK and India.
Unlike the situation following the Fukushima crisis, in which the Japanese government in effect nationalized TEPCO, no bailout of Toshiba is expected to come to its rescue. ……..
NuGen Project Faces Investor Uncertainty
Toshiba will likely end its planned commitment for a 60% equity stake in the NuGen Consortium at the UK Moorside project located in Cumbria. An effort to build three 1150 MW Westinghouse AP1000 nuclear reactors will now need new investors or a new reactor vendor or both.
In the UK backers of the NuGen project are looking to see if the government will directly fund the effort with Westinghouse acting as a technology vendor uncoupled from its parent’s convoluted corporate structure. ……..
The question is whether South Korea would want to take on another major project while it is still completing the other three units in the UAE plus it has domestic reactors that have capital requirements. The risk of being overextended in terms of money and management capability is one the firm will likely weigh relative to its interest in entering the UK nuclear market.
It is also less likely that Chinese state owned nuclear firms will have an appetite for further investments in the UK’s new nuclear build. They already have a full plate. Two firms have combined to take a 33% stake in the massive Hinkley Point C project. Also, they have also committed to enter the costly and lengthy Generic Design Assessment effort for the Hualong One reactor.
The two firms building the units at Fangchenggang hope to export the Hualong One to the UK for the Bradwell site once the Hinkley project is complete sometime in the mid-2020s. The firms have plans for a majority equity stake in the Bradwell project which could cost $10 billion. That’s a lot to take on and the prospect of being overextended is very real.
NPCIL Sees Andhra Pradesh as Now Being “Impossible”
Efforts by Westinghouse to close a deal to build six AP1000s for NPCIL at a coastal site in the southern state of Andhra Pradesh will go by the boards. The Indian government has not make any official statement about Toshiba’s problems. However, Reuters reported that it was told it now looks to be “impossible” for the six unit project to move ahead.
The Indian utility had been seeking U.S. Export Import Bank loan guarantees for the project which has cost estimates of at least $15 billion. Congress throttled the bank’s loan powers in 2015 and is unlikely to loosen the restraints for a project sponsored by Toshiba, at least in its current financially distressed state.
What Future for Westinghouse?
The risks that Westinghouse faces even if the reactor division is able to establish itself as an independent vendor to EPC firms and investors include keeping its work force intact during what could be a lengthy transition. Layoffs and cost cutting could reduce the core competencies of the firm and its ability to meet the service needs of existing customers much less be a vendor of nuclear technologies for new projects…..

The nuke biz is going down like dominoes. Hitachi announces a nearly $6.2 billion loss on its U.S. uranium enrichment joint effort with GE.
Electronics giant Hitachi Ltd. is set to lose tens of billions of yen this fiscal year due to the withdrawal from a project to develop a new method of uranium enrichment by a joint venture in the United States.
The loss, forecast by Hitachi on Feb. 1, was disclosed shortly after Toshiba Corp. made a similar announcement last month of deficits brought on by its nuclear power business.
Hitachi is expected to report a 70 billion yen ($620 million) non-operating loss by the time books are closed for fiscal 2016 at the end of March, said Mitsuaki Nishiyama, a senior vice president of the Tokyo-based conglomerate, in a news conference on the company’s performance through the third quarter.
The deficit is largely attributed to the joint venture GE Hitachi Nuclear Energy Inc. withdrawing from the uranium enrichment project. Due to this decision, Hitachi no longer expects any profits from the North Carolina-based company, of which it owns 40 percent and the rest by General Electric.
After allocating the losses, the value of Hitachi’s share of the joint venture comes to only about 11 billion yen.
Despite the gloomy news, Nishiyama said that “there are no more large deficit risks.”
Hitachi and GE were expecting more nuclear power plants to be built when they launched the joint fuel enrichment business, but orders have been sluggish across the globe, forcing the project to be shelved.
Nevertheless, Hitachi will be sticking with its nuclear power business. The company said that it plans to proceed with its project to build a plant in Britain by ensuring costs are thoroughly managed.

The writing is on the wall. Ban uranium mining now: “Tepco’s termination of the contract would affect about 9.3 million pounds of uranium deliveries through 2028, worth about $1.3 billion in revenue.”
Cigar Lake, in northern Saskatchewan, Canada, is the world’s highest-grade uranium mine.
Uranium miner Cameco (TSX:CCO; NYSE:CCJ) is weighing its options after a key Japanese customer attempted to cancel its contract, which would mean $1.3 billion in lost revenue for the Canadian company.
Tokyo Electric Power Company Holdings (TEPCO), the operator of Japan’s wrecked Fukushima nuclear plant, issued a termination notice for a uranium supply contract on Jan. 24 and, earlier this week, it said it would not accept a delivery that was scheduled for Feb.1.
Such contract cancellation would affect about 9.3 million pounds of uranium deliveries through 2028, including about 855,000 pounds annually in 2017, 2018 and 2019, Cameco said.
Shares collapsed on the news. They were trading down 12.5% to Cdn$14.50 in Toronto at 1:00 pm, and 13.3% down in New York to $11.06 at 1:26 pm ET.
Cameco said the Japanese power company has cited forces beyond its control — specifically government regulations arising from the 2011 Fukushima nuclear accident — that have prevented the operation of its nuclear plants.
The Canadian firm insisted that there’s no basis for terminating the contract and considers TEPCO to be in default. It said it will pursue its rights — including binding arbitration.
“We are surprised and disappointed that TEPCO is seeking to terminate its contract given all the past productive discussions we have had to date,” Cameco’s president and CEO Tim Gitzel said in the statement.
The company noted it has sufficient financial capacity to manage any loss of revenue in 2017 as a result of the dispute.
Including income coming from TEPCO, Cameco expects 2017 earnings will range between $2.1 billion to $2.2 billion. More information on the uranium miner’s financial position will be released next week.

Hitachi to take a 70 billion yen hit after U.S nuclear project fails, Asahi Shimbun By SATOSHI SEII/ Staff Writer February 2, 2017 Electronics giant Hitachi Ltd. is set to lose tens of billions of yen this fiscal year due to the withdrawal from a project to develop a new method of uranium enrichment by a joint venture in the United States.

Cameco to contest Tepco’s termination of supply contract
Cameco announced today that Tokyo Electric Power Company Holdings (Tepco) has issued a termination notice for a uranium supply contract with Cameco Inc that it does not accept. “Cameco Inc sees no basis for terminating the contract, considers Tepco to be in default, and will pursue all its legal rights and remedies,” the Saskatchewan, Canada-based uranium producer said.
The Japanese utility confirmed yesterday it would not accept a uranium delivery scheduled for 1 February and would not withdraw the contract termination notice it provided to Cameco on 24 January, according to Cameco’s statement. Tepco alleges that an event of ‘force majeure’ has occurred because it has been unable to operate its nuclear generating plants for 18 consecutive months due to government regulations arising from the Fukushima nuclear accident in March 2011.
“We are surprised and disappointed that Tepco is seeking to terminate its contract given all the past productive discussions we have had to date,” said Tim Gitzel, president and CEO of Cameco. “For the past six years we have worked in good faith with Tepco to restructure this contract, and would continue to do so if there was any basis for a commercial resolution. During the past week we tried to engage Tepco to obtain clarification given conflicting information we had received previously from them and only received confirmation of their intent to terminate the contract yesterday.”
Cameco will “vigorously pursue” remedies to recover value for its shareholders and other stakeholders, Gitzel added.
Under the contract, Tepco has already received and paid for 2.2 million pounds of uranium since 2014. The termination would affect about 9.3 million pounds of uranium deliveries through 2028, worth about $1.3 billion in revenue to Cameco, including about $126 million in each of 2017, 2018 and 2019 based on 855,000 pounds of deliveries in each of those years. In 2017, Cameco’s consolidated revenue, including the Tepco volume, is expected to range between $2.1 billion to $2.2 billion.
Cameco said it will be “moving expeditiously” to enforce its rights under the uranium supply contract to recover losses arising from Tepco’s actions.
“As with any commercial dispute, it will take some time for a resolution to be achieved, particularly if it proceeds all the way to arbitration,” Cameco said.
The company, which is scheduled to release its annual results after markets close on 9 February, said it has “sufficient financial capacity” to manage any loss of revenue in 2017 as a result of the dispute.
A spokesman for Tepco said: “We have terminated the uranium concentrate supply agreement with Cameco by giving written notice to Cameco in accordance with the terms and conditions of the agreement. We are aware that Cameco is showing their objection to our assertion of termination. However, our notice complies with the agreement and we will take appropriate action.”

Tepco scraps uranium supply contract with Canada’s Cameco
Feb 1 Canadian uranium producer Cameco Corp said on Wednesday that Tokyo Electric Power (Tepco) , the operator of Japan’s wrecked Fukushima nuclear plant, had scrapped its uranium supply contract with the company.
Shares of Cameco slid 12.2 percent to C$14.55 in early trading on Wednesday.
The company, one of the world’s largest uranium producers, said it considered Tepco’s move to terminate the contract unfair and that it would pursue legal action.
Cameco said Tepco cited a force majeure for ending the contract as it had been unable to operate its nuclear plants for 18 straight months due to Japanese regulations arising from the 2011 Fukushima nuclear accident.
The company said it was notified of the contract termination by Tepco last week.
Tepco’s termination of the contract would affect about 9.3 million pounds of uranium deliveries through 2028, worth about C$1.3 billion ($995.41 million) in revenue to Cameco, the Saskatoon, Canada-based company said.
Cameco’s earnings before interest, taxes, depreciation and amortization could take a 10-15 percent hit in the near-term as a result of the Tepco dispute, said Edward Sterck, an analyst at BMO Capital Markets.
Tepco’s move comes amid a fall in demand for uranium that is largely a result of the Fukushima nuclear plant meltdown, which led to shutdowns of all of Japan’s nuclear reactors.
Some reactors have since come back online, but global inventories of the radioactive metal remain high.
Cameco warned late last year that the uranium market would remain depressed until Japan’s nuclear reactors were restarted and excess supply was depleted.
Cameco also said it expected 2017 revenue of C$2.1 billion to C$2.2 billion, inclusive of Tepco’s volume, adding that it could withstand any potential loss of revenue this year from the dispute.
