Japan’s nuclear regulators have affirmed that Tokyo Electric Power Company is eligible to operate nuclear reactors again, but they have imposed some conditions.
The members of the Nuclear Regulation Authority made the decision at a meeting on Wednesday.
They have been debating whether or not to give the utility a green light to restart 2 reactors at the Kashiwazaki-Kariwa plant in Niigata Prefecture, central Japan.
TEPCO is the operator of the crippled Fukushima Daiichi plant.
During the meeting, a plan was put forth. According to the plan, TEPCO must express in its safety regulations its determination to tackle the decommissioning of the Fukushima Daiichi plant and its determination to prioritize safety over economic efficiency. In return, the regulators will certify that the company is eligible to operate nuclear reactors.
The plan also requires the industry ministry to make its intention to supervise the company clear.
At the meeting on Wednesday, the regulators agreed to certify that TEPCO is eligible to operate reactors as long as the industry ministry and the president of TEPCO agree to the provisions in the plan.
The regulators will compile a report that will effectively certify that TEPCO has their approval to restart the 2 reactors in Niigata.

Japan | Eligibility, Tepco |
Leave a comment
The nation’s nuclear watchdog gave conditional approval Sept. 13 to Tokyo Electric Power Co.’s application to resume operations of its Kashiwazaki-Kariwa nuclear plant.
It marks the first time that reactors operated by TEPCO, which manages the crippled Fukushima No. 1 nuclear plant, have passed more stringent reactor regulations imposed by the Nuclear Regulation Authority after the triple meltdown in 2011.
The two reactors at the plant in Niigata Prefecture–the No. 6 and No. 7 units–are the first boiling-water reactors in Japan to clear the regulations. They are the same type as the reactors at the Fukushima plant.
The NRA already accepts that TEPCO has the technological know-how to operate the Kashiwazaki-Kariwa plant, one of the world’s largest.
But it had harbored doubts about the company’s fitness to operate a nuclear plant, given its tendency to put its balance sheet ahead of safety precautions.
The NRA ordered TEPCO to provide in the legally required safety code a detailed explanation of procedures it will take to ensure that the Kashiwazaki-Kariwa plant is operated safely.
That way, the watchdog body aims to make the utility legally accountable if problems arise.
It will also closely monitor the utility’s actions in adhering to the safety code once the NRA approves the measures proposed by TEPCO.
The NRA will summon Tomoaki Kobayakawa, the new president of TEPCO, to request a more demanding safety code from the company.
As another condition for a restart, the NRA called for the industry ministry’s clear-cut commitment to oversee TEPCO’s compliance with safety if it is satisfied with the utility’s pledge to respond appropriately to the decommissioning of the Fukushima No. 1 nuclear plant. The industry ministry oversees the nuclear industry.
Despite the NRA’s conditional approval, the utility will need to gain consent from local governments for a restart.
Niigata Governor Ryuichi Yoneyama, who took office last year, has made it clear that he will not agree to the restart until the prefectural government completes its investigation into the Fukushima nuclear disaster to determine what went wrong. The investigation is expected to take several years.
In an effort to underscore its eligibility as an operator of a nuclear plant, TEPCO submitted a written pledge in August that it is “determined to take the initiative in addressing the needs of victims in Fukushima Prefecture and accomplish the decommissioning of the Fukushima No. 1 nuclear power plant.”
If the safety code and the industry minister’s commitment are secured, the NRA concluded that the utility will be eligible to resume operations of the Kashiwazaki-Kariwa plant.
Shunichi Tanaka, chairman of the NRA, said at the Sept. 13 meeting that TEPCO’s vow in August is “binding.”
The NRA indicated that if TEPCO fails to adhere to its “promise” to heed to safety, it will exercise the power to suspend the Kashiwazaki-Kariwa plant’s operations or revoke its license to operate it.
The Kashiwazaki-Kariwa plant has seven reactors. The No. 6 reactor and the No. 7 reactor started operations in 1996 and 1997, respectively. Each has a capacity of 1.36 gigawatts.

Japan commission supports nuclear power despite Fukushima, Kedger Enquirer
BY MARI YAMAGUCHI, Associated Press, SEPTEMBER 14, 2017 TOKYO
Japan’s nuclear policy-setting Atomic Energy Commission called Thursday for nuclear power to remain a key component of the country’s energy supply despite broad public support for a less nuclear-reliant society.
The commission recommended in a report that nuclear power account for at least 20 percent of Japan’s energy supply in 2030, citing a previous government energy plan. It said rising utility costs caused by expensive fossil fuel imports and slow reactor restarts have affected Japan’s economy……..
Thursday’s report comes as regulators are making final preparations to certify the safety of two reactors at the Kashiwazaki-Kariwa nuclear plant in northern Japan, also operated by TEPCO. The utility says restarting the Kashiwazaki plant, one of its three nuclear plants, is vital to finance the massive cost of the Fukushima cleanup and compensation for disaster-hit residents.
The Nuclear Regulation Authority on Wednesday deemed TEPCO “competent” to run the plant safely and its final greenlight is expected within weeks, though its actual restart could be months away, after an on-site inspection and local consent. Many Japanese oppose the Kashiwazaki plant’s restart, saying TEPCO should not be allowed to operate a nuclear plant until it fully investigates the cause of the Fukushima accident and completes the cleanup.
The report also endorsed Japan’s ambitious pursuit of a nuclear fuel cycle program using plutonium, despite a decision last year to scrap the Monju reactor, a centerpiece of the plutonium fuel program, following decades of poor safety records and technical problems. Japan faces growing international scrutiny over its plutonium stockpile because the element can be used to make atomic weapons.
Japan currently has a stockpile of 47 tons of plutonium — 10 tons at home and the rest in Britain and France, which reprocess and store spent fuel for Japan. Japan plans to start up its controversial Rokkasho reprocessing plant next year, but critics say that would only add to the problem.
Without the prospect of achieving a plutonium-burning fast reactor, Japan has resorted to burning a mixture of plutonium and uranium fuel called MOX in conventional reactors as a last ditch measure to consume plutonium. The report calls it “the only realistic method of making use of plutonium.”
The need to reduce its plutonium stockpile adds to Japan’s push for reactor restarts. It would require 16 to 18 reactors to burn enough MOX to keep its plutonium stockpile from growing, according to a pre-Fukushima accident target set by the Federation of Electric Power Companies of Japan, an umbrella group for Japanese utilities. The target is unchanged, though widely seen as too optimistic.

Times 7th Sept 2017, Japan should discuss hosting nuclear weapons on its territory, a former
defence minister said in a sign that the North Korean threat is changing
the military balance in the region. In what would once have been a shocking
breach of taboo in the only country to have suffered the ravages of atomic
bombs, Shigeru Ishiba said that Japan should debate the abolition of what
are known as the “three non-nuclear principles” — not producing or
possessing nuclear weapons or allowing them on Japanese soil.

https://www3.nhk.or.jp/nhkworld/en/news/20170910_02/ People in the Japanese city of Nagasaki have staged a sit-in to voice their opposition to the use of nuclear weapons. This comes amid growing concerns over North Korea’s military provocations.
The protest was held on Saturday as North Korea marked the 69th anniversary of the country’s founding.
Nagasaki suffered an atomic bombing toward the end of World War Two. The attack occurred on August 9th, 1945. A group of survivors and others hold an event to remember the bombing on the 9th of every month at the city’s Nagasaki Peace Park.
About 80 people, including survivors of the atomic bombing and high school students, took part in Saturday’s protest.
Koichi Kawano, who heads a group of survivors, says he wants to urge the Japanese government to do more to discourage Pyongyang from conducting nuclear tests.
Another participant, Sachiho Mizoguchi, is one of the high school students who ask people to sign a petition calling for the abolition of nuclear weapons. She said she took part in the sit-in to protest against the North’s nuclear tests.
Eiji Okumura, a survivor of the atomic bombing, says North Korea conducted a nuclear test after the United Nations took a step toward the creation of a nuclear-free world by adopting a treaty that banned nuclear weapons. Okamura said he cannot tolerate the North’s latest nuclear test, and he wants to express his anger through the sit-in.

Japanese nuclear plant may be on quake fault line https://www.theguardian.com/world/2007/jul/19/nuclear.japan
· Leak during tremor worse than originally admitted
· IAEA calls for openness in investigation of errors Justin McCurry in Tokyo , July 2007 The world’s biggest nuclear power station faces an uncertain future after it emerged yesterday that it may lie directly above the fault line that triggered Monday’s earthquake in which nine people died and more than 1,000 were injured.
The Kashiwazaki-Kariwa plant – the biggest in the world in terms of output capacity – shook violently when a magnitude 6.8 earthquake struck Niigata prefecture in northern Japan on Monday morning. The plant was not designed to resist shaking caused by earthquakes of greater than magnitude 6.5.
On another day of embarrassment for Japan’s nuclear power industry, the Tokyo Electric Power Company (Tepco), which operates the plant, said the amount of radioactivity in water that leaked into the sea during the earthquake was 50% higher than it had originally said. The firm blamed a calculation error and said the levels were still well within safety standards.
Late yesterday it also said that 400 drums – not 100 as first reported – of low-level radioactive waste had toppled over during the quake. About 40 lost their lids, spilling their contents on to the ground as they fell. The spillage was one of more than 50 malfunctions the plant experienced in the immediate aftermath of the quake.
International nuclear inspectors said they were concerned by Tepco’s apparent lack of preparedness for such a powerful quake.
“It is clear that this earthquake … was stronger than what the reactor was designed for,” Mohamed ElBaradei, head of the International Atomic Energy Agency, told reporters in Kuala Lumpur. “I would hope and I trust that Japan would be fully transparent in its investigation.”
The mayor of Kashiwazaki, Hiroshi Aida, ordered Tepco to close the plant indefinitely. “The safety of the plant must be assured before it is reopened,” he said. The closure has forced the firm to ask six other power utilities to supply it with additional electricity through to the end of September to avoid power cuts when demand peaks later this summer.
Tepco is under pressure to explain why it took so long to inform the authorities of radioactive leaks and why just four employees were on hand to tackle a fire inside an electrical transformer that was extinguished only after firefighters arrived almost 90 minutes later.
The mishaps have raised questions about the wisdom of building nuclear power stations in a country where earth tremors are recorded, on average, every few minutes. New safety regulations were brought in last year, but upgrading ageing reactors to withstand larger tremors will require huge investment.
Akira Fukushima, of Japan’s Nuclear and Industrial Safety Agency, said no irregularities had been found in critical areas of the plant, but added: “It is possible that the epicentre fault line does run beneath the power plant.”
Inspectors reportedly identified four fault lines in the area while conducting a geological survey before work began on the Kashiwazaki plant in 1980, but concluded that they were inactive.
The Citizen’s Nuclear Information Centre said that the fault believed to have triggered the earthquake was not discovered during pre-construction surveys. “Clearly Japan’s earthquake safety standards are inadequate,” it said in a statement.
Tepco’s president, Tsunehisa Katsumata, defended the firm. “It is hard to make everything go perfectly … I think fundamentally we have confirmed that our safety measures work,” he said.
Japan, which has very few indigenous energy sources, depends on 55 nuclear plants for 30% of its electricity. Despite mounting public opposition, it plans to increase capacity to 40% by the end of the decade.

World’s Largest Nuclear Power Plant One Step Closer To Operation http://oilprice.com/Latest-Energy-News/World-News/Worlds-Largest-Nuclear-Power-Plant-One-Step-Closer-To-Operation.html By Irina Slav – Sep 07, 2017, The Kashiwasaki-Kariwa nuclear power plant, the world’s largest, may get clearance to resume operations after six years of dormancy following the Fukushima disaster. The Japanese Nuclear Regulation Authority (NRA) granted the plant’s operator, Tepco, a qualified approval of its safety plan, and it could grant it effective approval as early as next week.
While the watchdog could issue a formal approval for Kashiwasaki-Kariwa’s restart later this fall, according to the Nikkei Asian Review, the actual resumption of the reactors is questionable: there is strong local community opposition to nuclear power as fears of another meltdown still linger.
Regulators have conducted technical safety evaluations of the plant, whose reactors are of the same kind as those that melted down in Fukushima, but there are still some reservations regarding Tepco’s safety efforts. The NRA has requested that Tepco’s proposed safety measures for Kashiwasaki-Kariwa be made more legally binding, and has set up a panel to devise ways to guarantee the utility keeps its word.
Even if the NRA approves the restart of the plant, however, the Niigata prefecture is unlikely to support it with an approval of its own. The governor, Ryuchi Yoneyama, is an outspoken opponent of nuclear power, and following the news of NRA’s pending approval said that the prefecture had “absolutely no intention of approving a restart” of the Kashiwasaki-Kariwa facility before an safety inspection of Fukushima was completed.
Tepco first applied for approval to restart two of Kashiwasaki-Kariwa’s seven reactors back in 2013, and has since worked to fulfill all safety requirements that regulators imposed. The company’s shares, however, jumped 3 percent on the news of NRA’s approval despite the slim chance of Kashiwasaki-Kariwa actually returning to operation.
The Fukushima disaster, caused by a tsunami in 2011, displaced 160,000 people, many of them permanently, and led to the shut down of all 50 nuclear reactors in the country. The cost of the disaster is estimated at US$197 billion.

Nuclear regulator does dizzying U-turn on TEPCO reactor restart plans
From left, the No. 5, 6 and 7 reactors at Tokyo Electric Power Co.’s Kashiwazaki-Kariwa nuclear power plant are seen in Kashiwazaki, Niigata Prefecture, in this April 21, 2016 file photo.
Tokyo Electric Power Co. (TEPCO), the utility responsible for the Fukushima No. 1 nuclear plant and its March 2011 triple meltdown, is aiming to get the reactors at its other power plants back on line.
The Nuclear Regulation Authority (NRA), which must approve any restarts, had been holding to a very strict line on TEPCO applications. However, on Sept. 6 the NRA abruptly changed track, taking a more sympathetic attitude and indicating that the No. 6 and 7 reactors at the utility’s Kashiwazaki-Kariwa nuclear plant in Niigata Prefecture would likely pass their safety inspections — a prerequisite for restart approval.
Despite the NRA’s suddenly sunny attitude, the prefectural government has not budged from its more cautious position. And TEPCO, which has made the Kashiwazaki-Kariwa plant a chief pillar of its business recovery plans, cannot flip the reactors’ “on” switch without the prefecture’s imprimatur, meaning the plant still has no clear restart schedule.
When the NRA summoned TEPCO President Tomoaki Kobayakawa and other top managers on July 10 this year to testify on the utility’s competence to keep running nuclear plants, authority chairman Shunichi Tanaka was unequivocal and unforgiving.
Nuclear Regulation Authority Chairman Shunichi Tanaka speaks to the Mainichi Shimbun during an Aug. 29, 2017 interview. (Mainichi)
“If TEPCO is unwilling or unable to finalize the decommissioning of the Fukushima (No. 1 station) reactors, it is simply not qualified to restart the Kashiwazaki-Kariwa plant,” Tanaka told the executives, adding, “I don’t see TEPCO showing any independent initiative whatsoever.”
The NRA chairman was referring to the longstanding problems with contaminated water and radioactive waste disposal plaguing TEPCO’s Fukushima plant decommissioning efforts. The utility tends to focus too much on trying to read the government’s mind on any and all Fukushima issues — an attitude that has long drawn NRA criticism.
When the NRA inspected the Kashiwazaki-Kariwa plant’s No. 6 and 7 reactors, it added a new evaluation category to the usual technological checklist, though it was not part of the new safety standards: “eligibility.” That is, TEPCO’s eligibility to run a nuclear power plant at all. After all, it was one of TEPCO’s plants that had succumbed to the worst nuclear disaster since Chernobyl. “TEPCO is different from other (power) companies,” Tanaka had said.
TEPCO President Kobayakawa and Chairman Takashi Kawamura are also a source of NRA concern. The two had no role in the utility’s response to the 2011 meltdowns, and Kobayakawa replaced a much more experienced hand in Naomi Hirose, a TEPCO managing director when the disaster struck. After his NRA dressing-down in July, Kobayakawa apparently visited the Fukushima disaster zone seven times.
However, there has been an apparent U-turn in Tanaka’s stance. A document submitted on Aug. 25 to the NRA under Kobayakawa’s name was sewn with phrases like, “We will carry the (Fukushima) reactor decommissioning through to the end,” and other terms suggesting a determined TEPCO attitude. At the same time, the document was bereft of details on specific preparedness measures or progress benchmarks for the decommissioning work.
Nevertheless, when Kobayakawa again appeared before the NRA on Aug. 30, the body indicated its acceptance of TEPCO’s position. Taking the contaminated water problem “as one example,” Tanaka stated that he recognized TEPCO’s lack of concrete countermeasure planning couldn’t be helped under the circumstances. One NRA executive revealed to the Mainichi Shimbun, “We avoided demanding a detailed (disposal measures) plan because we don’t legally have that authority, and doing so could pose legal risks.”
Pro-TEPCO sentiment was on conspicuous display when the NRA met again on Sept. 6, including acting Chairman Toyoshi Fuketa’s declaration that he “felt TEPCO’s drive to pass on the lessons of the (Fukushima nuclear) accident.”
Committee member Nobuhiko Ban stated that while the document the utility had submitted in the summer was a “declaration of intent,” he was “concerned over whether this alone can constitute eligibility” to run a nuclear plant. However, Tanaka wrapped up discussion by saying that “circumstances are not such that we can deny (TEPCO’s) eligibility.”
Tanaka will leave his NRA post on Sept. 18 after completing his five-year term in the chairmanship, and at a post-meeting news conference he was asked if he had wanted to bring the TEPCO issue to a close while in office.
“I can’t say that I’ve never felt that way,” Tanaka replied.

NRA doubts TEPCO’s safety vow in Niigata, plans legal move
Tokyo Electric Power Co. wants to restart the No. 6 and No. 7 reactors, shown in the forefront, at its Kashiwazaki-Kariwa nuclear plant in Niigata Prefecture.
The Nuclear Regulation Authority, skeptical of Tokyo Electric Power Co.’s promise to put safety ahead of profits, plans to gain legal assurances before allowing the embattled utility to start operating nuclear reactors again.
TEPCO has applied to restart two reactors at its Kashiwazaki-Kariwa plant in Niigata Prefecture, which would be the first run by the company since the disaster unfolded at its Fukushima No. 1 nuclear plant in March 2011.
Although NRA members agreed that the No. 6 and No. 7 reactors at the Kashiwazaki-Kariwa plant passed new regulations on technological aspects, they could not agree on whether the company has learned its lessons about safety management since the triple meltdown at the Fukushima plant.
To ensure TEPCO will put safety at the forefront of its operations, the NRA is considering holding the utility legally responsible for completing the entire decommissioning process of the Fukushima No. 1 nuclear plant.
The regulator expects to draft a checklist to verify the Kashiwazaki-Kariwa plant’s safety and other steps before it makes a final decision on whether to allow TEPCO to restart the reactors. The next meeting is scheduled for Sept. 13.
The NRA had previously determined that 12 reactors at six nuclear plants met new nuclear reactor regulations shortly after completion of their technological examinations.
The NRA also finished its technological examinations of the No. 6 and No. 7 reactors, the newest ones at the Kashiwazaki-Kariwa plant.
The plant has seven reactors, making it one of the largest nuclear power stations in the world. The two reactors that TEPCO wants to put online each has a capacity of 1.36 gigawatts.
TEPCO has said the resumption of the reactors are needed to turn around its business fortunes.
But NRA commissioners are reluctant to allow TEPCO to bring the plant online based solely on the results of the technological screening.
After the chairman and president of the utility were replaced in June, the NRA summoned the new top executives in July.
The watchdog demanded that they give a written response to the regulator’s position that TEPCO “is not qualified to operate the Kashiwazaki-Kariwa plant, given the seeming lack of determination and spotty track record to take the initiative in decommissioning (the Fukushima No. 1 plant).”
In August, the company submitted a paper to the NRA promising to “take the initiative in addressing the problem of victims of the nuclear disaster and to fulfill the task to decommission the plant.”
The paper also said the company “has no intention whatsoever to place economic performance over safety at the (Kashiwazaki-Kariwa) plant.”
Tomoaki Kobayakawa, the new president of TEPCO, called the paper a “promise to the public.”
Although the NRA commissioners on Sept. 6 recognized TEPCO’s commitment to safety to a certain degree, doubts remained.
Nobuhiko Ban, an NRA member who is a specialist on radiological protection, called for a system that would keep TEPCO committed to safety management in the future.
“Is it all right for us to take TEPCO’s vow at face value?” he said.
The NRA then decided to consider legal ways to hold TEPCO accountable for safety issues.

Nuclear plant operator halts uranium production, https://www3.nhk.or.jp/nhkworld/en/news/20170903_04/, The operator of a uranium enrichment plant in northern Japan has suspended uranium production to see if there are problems with its quality control system.
The plant in Rokkasho Village, Aomori Prefecture, is the only commercial facility in Japan to enrich uranium for nuclear power generation. A division of Japan Nuclear Fuel Limited that operates the plant was ordered to improve its quality control system last year.
It reported to the president that steps were taken, which turned out not to be true.
The Nuclear Regulation Authority then approved measures to prevent similar irregularities. The operator met the government requirements for producing uranium in May.
In one of a series of safety mishaps, a fire started at an emergency power generator. The operator had failed to replace parts for 28 years, more than 10 years longer than recommended by the manufacturer.
Officials at the authority said they wonder if the operator has the ability to determine problems and challenges. Japan Nuclear Fuel decided to take uranium out from enrichment facilities and once again check quality control problems.

Hitachi UK reactors to get full Japanese loan insurance https://asia.nikkei.com/Politics-Economy/Policy-Politics/Hitachi-UK-reactors-to-get-full-Japanese-loan-insurance, Lenders seek guarantees as nuclear projects face post-Fukushima cost overruns, 2 Sept 17, TOKYO — Japan intends to fully insure bank loans for one of Hitachi‘s British nuclear plant projects in order to encourage domestic lenders to finance a particularly risky type of infrastructure export that Prime Minister Shinzo Abe’s government seeks to promote.
When Abe met with U.K. counterpart Theresa May here Thursday, the two leaders reaffirmed bilateral cooperation on nuclear plant construction. Japan’s support will include coverage for two reactors at the proposed Wylfa Newydd nuclear station in Wales — a rare example of loan insurance for a project in an advanced economy.
State-owned Nippon Export and Investment Insurance will write the loan insurance for reactors, which Hitachi will build through British arm Horizon Nuclear Power. The Japanese conglomerate, together with Tokyo and London, will conduct working-level talks to hash out a funding support framework, with the aim of breaking ground in 2019.
The project is estimated to cost over 2 trillion yen ($18.1 billion). Hitachi, the U.K. government and two state-backed entities — Japan Bank for International Cooperation and the Development Bank of Japan — are expected to pick up part of the tab. But private-sector financing will also be needed to close the funding gap.
NEXI, which normally indemnifies private lenders for 90-95% of financing, will enter into talks with Japanese banks toward fully guaranteeing loans for the Wylfa project.
Nuclear project costs have tended to balloon since since Japan’s 2011 Fukushima disaster owing to increased safety precautions. Seeing a higher risk of debt default, Japanese megabanks Bank of Tokyo-Mitsubishi UFJ and Mizuho Bank have sought full coverage by NEXI for any loans for nuclear plant development. Such insurance typically covers financing for projects in developing countries. NEXI is expected to impose conditions, such as a loan period of several decades, in return for an exception.
An accident or other troubles at the plant could expose BTMU and Mizuho to lawsuits from third parties because the banks would bear responsibility for financing the project. The two banks will decide on Wylfa financing based partly on discussions between Tokyo and London concerning damage compensation.
A default on the Wylfa loans would entail a taxpayer-funded repairs to the balance sheets of NEXI and JBIC. The loan insurance proposal is likely to spark a debate on whether promoting infrastructure exports in this way is worth the risk. The Abe government, for its part, will try to use the NEXI assurances to elicit more funding, public and private, from the British side.
With little prospect of constructing new reactors in Japan following the meltdowns at the Fukushima Daiichi nuclear power plant, domestic builders have focused their business offshore. Chinese state-owned enterprises are undertaking more global infrastructure projects, emboldening those who argue that Japan will be left behind in the race for overseas orders unless the country takes risks. In 2015, the U.K. became the first developed nation to approve a Chinese-made reactor.

NRA eager to clear Kashiwazaki-Kariya plant
Tokyo Electric Power Company Holdings Inc. employees take part in a drill in the simulator of the central control room for a reactor inside the seismic isolation building at the company’s Kashiwazaki-Kariwa nuclear power station in Kashiwazaki, Niigata Prefecture, in February 2015.
Two Tokyo Electric reactors at the massive Kashiwazaki-Kariwa power station in Niigata Prefecture are expected to clear the initial safety hurdle for restarts soon, sources said Friday.
According to the sources, the Nuclear Regulation Authority will start talks on the issue on Wednesday, with a view to compiling a document that will certify the two units passed the new safety requirements introduced after the Fukushima nuclear crisis.
Tokyo Electric Power Company Holdings Inc. has been struggling to recover ever since the triple core meltdown in March 2011 because the seven-reactor Niigata plant is a crucial money maker. The utility has spent years trying to restart the plant, which is the only nuclear complex it runs aside from the disaster-hit Fukushima No. 1 plant in Fukushima Prefecture.
It filed for safety assessments for reactor Nos. 6 and 7 in September 2013.
The NRA wants to reach a conclusion on the issue before Chairman Shunichi Tanaka’s five-year term expires on Sept. 18, the sources said. But the move may trigger public criticism because Tepco still has a long way to go to scrap the ruined reactors at Fukushima No. 1, which was engulfed by quake-triggered tsunami and lost all power.
The Kashiwazaki-Kariwa complex is one of the world’s largest nuclear power plants and has an output capacity of 8.2 million kilowatts. Units 6 and 7 are boiling water reactors — the same type as the ones at Fukushima No. 1 — and the newest of the seven sitting along the Sea of Japan coast.
The governments hosting the Kashiwazaki-Kariwa plant are also cautious about restarting the units, with Niigata Gov. Ryuichi Yoneyama saying it will take “around three to four years” for the utility to win local consent on the matter.
Tepco, which is facing massive compensation payments and other costs from dealing with the world’s worst nuclear crises since Chernobyl, has been desperate to restart the idled reactors so it can reduce spending on costly fossil fuel imports needed to run the thermal power plants making up for the nationwide nuclear shutdowns.
Some reactors at other utilities have already resumed operations, but Tepco has been under constant scrutiny to determine whether it is qualified to once again operate a nuclear power plant.
Some inside the NRA have been reluctant to move ahead with the safety review at Kashiwazaki-Kariwa. But Tanaka strongly wants to set a course on the issue before he leaves his position at the NRA, and this was one of the factors that led to the latest development in Niigata, the sources said.

Group: Water plan to remove Fukushima fuel ‘not viable’ http://www.asahi.com/ajw/articles/AJ201708310042.html, By KOHEI TOMIDA/ Staff Writer, August 31, 2017 The Asahi Shimbun A decommissioning organization on Aug. 31 formally recommended bypassing a safety measure to remove melted nuclear fuel from crippled reactors at the Fukushima No. 1 nuclear plant.
The Nuclear Damage Compensation and Decommissioning Facilitation Corp. (NDF) urged the central government and Tokyo Electric Power Co. to use the “airborne method” in which the melted fuel is removed even when the water level in the reactor containment vessel is kept low.
Proposals have been made to fill the containment vessels with water to restrain the spewing of radioactive materials during the fuel removal process.
But the NDF said that method is currently not viable because of the difficulties in patching up the holes in the containment vessels.
The government and TEPCO are expected to decide on a fuel removal method in September and confirm the specific steps next fiscal year.
The removal of equipment and other structural objects in and around the reactors must be completed before work can start on taking out melted fuel that remains in the pressure vessels.
The nuclear fuel that has seeped through the pressure vessels and landed at the bottom of the containment vessels will be the first to be removed.
Work will also have to be done to develop a robot arm that can remove fuel from the side of the containment vessel. Under the current schedule, removal of the melted fuel will start at one of the three, No. 1 to No. 3, reactors of the Fukushima No. 1 plant in 2021.
However, officials still do not know the exact location of the melted fuel in the reactors.
Hajimu Yamana, NDF president, pointed out there would likely be a need to combine various methods instead of pushing through with one specific procedure to meet the scheduled deadline.

Tepco faces another $5bn US suit over Fukushima nuclear disaster, Business Live, 24 AUGUST 2017 – 14:54 AGENCY STAFF TOKYO —Tokyo Electric Power Company Holdings (Tepco) said on Thursday it faces another US lawsuit over the 2011 Fukushima nuclear disaster, with the latest one demanding at least $5bn in compensation.
A total of 157 US residents who were supporting Fukushima victims at the time filed the class action suit in a California district court earlier this month against the utility and a US company…….
The plaintiffs, who joined aid efforts along with US troops shortly after the disaster, claim they were exposed to radiation because of the improper design, construction and maintenance of the plant.
They were seeking $5bn to cover the cost of medical tests and treatment needed to recover from the disaster, Tepco said in a statement.
They are also demanding compensation for physical, mental and economic damage but no further details such as a sum of money or the identities of the claimants were available.
It was the second multi-plaintiff suit filed against the utility in a US court following one by more than 200 individuals in 2013.
In Japan, more than 10,000 people who fled their homes over radiation fears have filed various group lawsuits against the government and the firm. https://www.businesslive.co.za/bd/companies/2017-08-24-tepco-faces-another-5bn-us-suit-over-fukushima-nuclear-disaster/
