“The Japan Atomic Energy Agency (JAEA) on Aug. 30 started work to decommission the Monju prototype fast-breeder reactor in Fukui Prefecture…
The decommissioning work is scheduled to take 30 years and cost $ 3.33 billion.”
Staff members of the Japan Atomic Energy Agency operate equipment to remove nuclear fuel assemblies from a storage tank at the plant of the Monju prototype fast-breeder reactor in Tsuruga, Fukui Prefecture, on Aug. 30.
August 30, 2018
The Japan Atomic Energy Agency (JAEA) on Aug. 30 started work to decommission the Monju prototype fast-breeder reactor in Fukui Prefecture, a once-promising project that struggled with problems, even in preparations for its dismantlement.
The work started a month later than scheduled because of a series of equipment trouble. The JAEA workers also face an enormous challenge because Japan has no experience in decommissioning a fast-breeder reactor.
The JAEA will use overseas experiences as a reference for the delicate process.
Before the start of the work, JAEA President Toshio Kodama told staff members in a speech at the plant in Tsuruga, “I want you to tackle this work by bracing yourselves.”
Monju had been a key facility in the government’s nuclear fuel recycling program.
Construction of the reactor started in 1985, but a series of accidents, including a sodium coolant leak in 1995, as well as cover-ups kept the reactor offline for most of its life.
In 2016, after 1 trillion yen ($9 billion) had been spent on the project, the government finally decided to abolish Monju.
The decommissioning work is scheduled to take 30 years and cost 375 billion yen.
One of the riskiest parts in the decommissioning process is handling the liquid sodium, which reacts strongly with water and air.
In the first of the four-stage decommissioning project, the JAEA will transfer 530 nuclear fuel assemblies, currently kept in the liquid sodium-filled nuclear reactor and storage tank, to a water-filled pool by fiscal 2022.
In the work that began on Aug. 30, the JAEA will remove 160 nuclear fuel assemblies from the storage tank, wash away the sodium, and place them in the pool.
From 2019, the agency will transfer nuclear fuel assemblies from the reactor to the storage tank and then to the pool.
In December this year, the JAEA will also start to transfer about 760 tons of sodium, which has not been exposed to radioactive substances, to its storage tank. Later, the agency will remove about 910 tons of radioactive sodium from the reactor and other equipment.
In the following stages, the agency will dismantle the nuclear reactor, the turbine and other facilities.
However, no decision has been made on how to dispose of the nuclear fuel removed from the reactor and the storage tank. Monju has used mixed oxide (MOX) fuel, which contains plutonium and currently cannot be reprocessed in Japan.
“It’s realistic to ask an overseas company to reprocess it,” said Toyoshi Fuketa, chairman of the Nuclear Regulation Authority, the government’s nuclear watchdog.
If reprocessing expenses in a foreign country are added, the overall decommissioning costs will sharply increase.

Japanese energy agency officials say they will continue to hold public briefing sessions on the disposal of highly radioactive nuclear waste.
The government last year released a map showing which parts of the country may be scientifically suited to hosting an underground disposal site.
The Agency for Natural Resources and Energy has so far invited residents to 55 briefing sessions. Most have taken place in prefectural capitals.
On Monday, the agency held a meeting in Tokyo to explain the sessions to regional officials.
Agency officials said participants tend to question whether highly contaminated nuclear waste can safely be stored in earthquake-prone Japan. They also express concerns over how local people’s opinions may be reflected.
The agency plans to hold further briefings, mainly in coastal areas that are considered to be relatively suitable for underground waste storage.
The districts cover about 900 municipalities.
The officials say they will decide on where to hold the briefing sessions after discussions with the municipalities.
The officials indicate they will continue approaching municipalities to investigate potential waste disposal sites. So far none have agreed to such studies.
Fukushima water release into sea faces chorus of opposition https://mail.google.com/mail/u/0/#inbox?compose=DmwnWtDqNzxklZTsLVvsRFtgBQZHzxshPgMCgrVGpNqZnjrqDwNNWbPprDwxPlNFzCVZnfDvsQwVCitizens and environmental groups have expressed opposition to the idea of releasing into the ocean water tainted with tritium, a radioactive substance, from Tokyo Electric Power Company Holdings Inc.’s disaster-stricken Fukushima No. 1 nuclear power plant.“Long-term storage (of the tritium-containing water) is possible from technical and economic standpoints,” Komei Hosokawa, 63, an official of the Citizens’ Commission on Nuclear Energy, said at a public hearing held in Tokyo on Friday by a subcommittee of the Agency for Natural Resources and Energy. “The radiation levels in the water will decrease during the long-term storage,” he added.
At a similar hearing held the same day in Koriyama, Fukushima Prefecture, Aki Hashimoto, a housewife from the city, said, “I never want to see further worsening of ocean pollution from radiation.”
Opinions objecting to the release of the tritium-contaminated water into the ocean were also heard at a hearing held in the Fukushima town of Tomioka on Thursday.
After Friday’s hearings, Ichiro Yamamoto, who heads the subcommittee, told reporters that many participants in the hearings said the tainted water should continue to be held in storage tanks.
The subcommittee will study the option of keeping the water in the tanks, he added.
Tepco is lowering the radiation levels in contaminated water at the Fukushima No. 1 plant using special equipment, but the device cannot remove tritium.
The tritium-tainted water is stored in tanks within the premises of the power plant, which was heavily damaged in the March 2011 earthquake and tsunami.
In 2016, an expert panel of the Agency for Natural Resources and Energy discussed five methods to dispose of the tritium-tainted water —injection deep into the ground, release into the sea after dilution, release into the air through evaporation, conversion into hydrogen through electrolysis, and burying it after it is solidified.
The panel estimated that the ocean release is the cheapest option, costing up to about ¥3.4 billion.
The Fukushima Prefectural Government and the Reconstruction Agency are looking to take legal action over the video over concerns it will stoke “unreasonable” fears of radiation in the Fukushima Prefecture, the Japan Times reports.
A senior official from the prefecture said they were “examining the video content”.
In the episode, Farrier is filmed taking a tour of areas affected by the 2011 meltdown of a nuclear plant in Fukushima where he suspects a meal served from a restaurant in Namie, a town in Fukushima Prefecture, has been contaminated by radiation.
It also shows the journalist enter a no-go zone around the Fukushima Daiichi nuclear power plant without permission from authorities, reporting from an abandoned game arcade, and tourists on a bus becoming distressed over rising radiation levels without information about the vehicle’s location.
The show has the journalist travel to different locations around the world associated with grim historical events, including the footsteps of serial killer Jeffrey Dahmer in Milwaukee, and voodoo rituals in Benin, West Africa.
JIJI TOMIOKA, FUKUSHIMA PREF. – The head of a fisheries industry group in Fukushima Prefecture expressed opposition on Thursday to the idea of releasing water containing radioactive tritium from a crippled nuclear plant in the prefecture into the ocean.
The tritium-tainted water is from Tokyo Electric Power Company Holdings Inc.’s Fukushima No. 1 nuclear power plant, which was damaged heavily in the powerful earthquake and tsunami in March 2011.
“At a time when harmful rumors are still circulating in Japan and some countries continue to restrict imports (of Fukushima goods), releasing the tainted water into the sea will inevitably deliver a fatal blow to the Fukushima fishery industry,” Tetsu Nozaki, who leads the Fukushima Prefectural Federation of Fisheries Cooperative Associations, said.
His remarks came during a public hearing held by a subcommittee of the Agency for Natural Resources and Energy in the Fukushima town of Tomioka.
The hearing was for the canvassing of opinions on how to deal with the tritium-tainted water. Releasing it into the sea has been proposed as one option. Similar hearings will be held in the city of Koriyama, Fukushima, and Tokyo on Friday.
Using special equipment, Tepco is lowering the radiation levels in contaminated water at the plant, but the device cannot remove tritium. While the processed water is kept in tanks within the premises of the nuclear power station, the amount of tainted water continues to increase as the plant’s damaged reactors need to be cooled continuously. Tepco is about to run out of suitable sites to construct new storage tanks, according to the government.
Discussions on ways to deal with the tritium-contaminated water are underway at the subcommittee of the government agency.
In a June 2016 report, an expert panel of the agency said that releasing the polluted water into the sea after it is diluted with fresh water would be relatively cheap and time-efficient.
Assemblies make moves to reject playing host to nuclear waste http://www.asahi.com/ajw/articles/AJ201808280029.html By CHIAKI OGIHARA/ Staff WriterAugust 28, 2018 More local assemblies are taking measures to send a strong message to the central government not to bother asking them to host storage facilities for nuclear waste.The moves, in the form of ordinances, were accelerated after the Ministry of Economy, Trade and Industry in July 2017 released its Nationwide Map of Scientific Features for Geological Disposal that classified areas around Japan into four colors denoting their suitability as storage sites for nuclear waste.
Electric power companies are looking for land plots to construct an interim storage facility for spent nuclear fuel. The central government is planning a final storage facility where high-level radioactive waste would be mixed with glass and vitrified before being buried more than 300 meters underground.
Twenty-two municipal assemblies now have ordinances that limit the entry of highly radioactive waste into their communities.
About half of the ordinances were adopted by 2005, followed by an extended period when concerns decreased about being chosen as a site for nuclear waste storage facilities.
But the release of the geological disposal map prompted five municipal assemblies to quickly adopt ordinances limiting the introduction of nuclear waste to their communities.
Dark green areas on the map show places deemed appropriate for hosting the final storage facility. They are all within 20 kilometers from the coast, have favorable geological features and are considered adequate for the transportation of waste.
About 900 municipalities fall into the dark green areas.
Light green areas on the map have favorable geological features but face problems in transporting the waste.
Orange areas are considered inappropriate from a geological standpoint, while silver areas are also deemed inappropriate because they have reserves of natural resources that could be mined in the future.
Between autumn 2017 and spring 2018, the village of Yamato and the towns of Higashi-Kushira and Kimotsuki–all in dark green areas in Kagoshima Prefecture–adopted ordinances to reject the acceptance of nuclear waste.
Two towns in Hokkaido passed similar ordinances. Biei, located in a light green area, took the action in April, while Urakawa, which lies mostly in a dark green area, adopted the ordinance in June.
Kagoshima Prefecture has the most municipalities–11–with such ordinances. In 2000 and 2001, six municipalities adopted the ordinances amid rising concerns that an interim spent fuel storage facility would be brought in. Between 2005 and 2015, four other municipalities followed suit.
The town of Yaku was among the first group, but its ordinance became invalid after it merged with Kami-Yaku to form the new town of Yakushima.
The Yakushima town assembly is now planning to submit an ordinance in its September session to reiterate its opposition to serving as a site for nuclear waste storage.
However, the law for nuclear waste storage would take legal precedence over any municipal ordinance, meaning that the local governments could still be asked to accept the nuclear waste.
The Nuclear Waste Management Organization of Japan (NUMO) is in charge of the final nuclear waste storage project, and it has held explanatory meetings around Japan about the geological disposal map.
At those meetings, NUMO officials have stressed that it would not force a locality to accept nuclear waste if the prefectural governor or municipal mayor was opposed.
Still, Kohei Katsuyama, chairman of the Yamato village assembly in Kagoshima Prefecture, said the ordinance serves as a strong sign of the municipality’s stance of rejecting any idea of serving as host of a nuclear waste storage facility.
Nuclear fuel removal to start at Monju reactor NHK, 28 Aug 18 The operator of Japan’s Monju prototype fast-breeder reactor plans to soon start removing its nuclear fuel from a storage container as part of the plant’s decommissioning.
The Japan Atomic Energy Agency plans to scrap the reactor in Tsuruga City in Fukui Prefecture, central Japan, over 30 years.
Work to move the fuel to a detached storage pool was to start in late July. But it was postponed due to equipment trouble including fogging up of monitoring camera lenses during trials.
Students submit nuclear abolition petition to UN https://www3.nhk.or.jp/nhkworld/en/news/20180829_06/ A group of Japanese high school students has visited the United Nations European headquarters in Geneva to submit a petition calling for the abolition of nuclear weapons.
The 20 “peace messengers” met Anja Kaspersen, the director of the UN Office for Disarmament Affairs, on Tuesday. Some of the students are from the atomic-bombed cities of Hiroshima and Nagasaki. The students showed Kaspersen photos taken immediately after the 1945 bombings. They told her the bombs not only killed many people but also forced survivors to live with burns and aftereffects.
They submitted about 100,000 signatures they had collected over the past year and urged the UN to do more to create a world with no nuclear weapons.
Kaspersen said the students’ campaign is not just about hope, but it is also helping young people in many countries to promote generosity and understanding.
The UN adopted the Treaty on the Prohibition of Nuclear Weapons last year, but nations possessing nuclear weapons and Japan have not joined it. Riko Shitakubo from Hiroshima said she renewed her resolve to keep trying to change the situation surrounding nuclear weapons.
Unfinished nuclear fuel plant had water leak NHK, 28 Aug 18The operator of a nuclear fuel reprocessing plant under construction in northern Japan says it found a water leak earlier this month at one of its facilities.
Japan Nuclear Fuel says an employee spotted the leak in the pipes of a storage pool at the plant in Rokkasho Village, Aomori Prefecture.
The operator found that the pipes were corroded in 20 places and one of them had a hole. They are located outdoors and used for inspections.
Nuclear waste briefings in coastal areas https://www3.nhk.or.jp/nhkworld/en/news/20180827_27/ Japanese energy agency officials say they will continue to hold public briefing sessions on the disposal of highly radioactive nuclear waste.

New earthquake probability scale https://www3.nhk.or.jp/nhkworld/en/news/20180828_18/ Japanese government officials have revised the chances for earthquakes linked to marine trenches in order to avoid misleading the public. The government’s task force for earthquake research released its assessment of quakes that may hit Japan, along with their probabilities of occurring within 30 years.
Currently, the chances of quakes linked to marine trenches are given in percentages.
But experts fear that such descriptions could cause misunderstandings. People might feel safe living in an area with a small quake possibility figure, such as 0.1 percent or less.
The task force said it has introduced a new 4-rank scale to describe quake probabilities.
The highest rank of 3 means having the biggest chance of a large-scale quake within 30 years– a chance of 26 percent or more. Rank 2 is for areas with the chance of a quake between 3 and 26 percent. The rank of 1 suggests quake probabilities of less than 3 percent. Another rank of X suggests the chances of a quake cannot be calculated due to a lack of data, but an imminent quake cannot be ruled out.
Under the new classification system, possible mega quakes, including along the Nankai Trough off the Pacific coast from central through western Japan, are ranked 3.
Toru Hasuike, a former employee of Tokyo Electric Power Co., talks about his new book in Kashiwazaki, Niigata Prefecture.
August 27, 2018
KASHIWAZAKI, Niigata Prefecture–Toru Hasuike, who worked at Tokyo Electric Power Co. for 32 years, has published another book that he says shows his former employer should be declared “ineligible” to operate nuclear power plants.
“Kokuhatsu” (Accusation), a 250-page book released on Aug. 27 by Tokyo-based Business-sha Inc., reveals episodes that underscore the utility’s culture of cover-ups and collusion, including how it stacked the decks in its favor for government approval of its new reactors, he said.
After graduating from the Tokyo University of Science, Hasuike, 63, had worked in TEPCO’s nuclear division, including a stint at the now-embattled Fukushima No. 1 nuclear power plant, from 1977 until he left the company in 2009.
His first book about the utility, titled “Watashi ga Aishita Tokyo Denryoku” (Tokyo Electric Power Co. that I loved), was released by Kyoto-based Kamogawa Co. in September 2011, a half-year after the disaster struck the Fukushima No. 1 nuclear plant.
In that book, Hasuike describes the day-to-day activities at TEPCO and the closed nature of the regional monopoly in a matter-of-fact tone. He does not accuse the company of cover-ups or collusion in the book.
“Back then, I believed that even TEPCO would transform itself (following the Fukushima nuclear disaster),” Hasuike said in an interview with The Asahi Shimbun in Kashiwazaki. “But TEPCO’s corporate culture of trying to cover up things and form collusive ties with authorities has not been overhauled. In my latest book, I wrote about all that I saw.”
Assigned to the utility’s main office in Tokyo, Hasuike, who had an engineering background, was primarily involved in work responding to nuclear regulators’ safety inspections of TEPCO’s plants as well as research into the disposal of high-level radioactive waste.
He said he documented a number of his experiences that epitomize the collusive ties between the utility and nuclear regulators before the 2011 Fukushima nuclear disaster.
Hasuike said these episodes made him question the feasibility of TEPCO’s new stated goal of pushing for organizational reform that puts safety management of its nuclear facilities above everything else.
Hasuike was born and raised in Kashiwazaki, Niigata Prefecture, a city that co-hosts TEPCO’s seven-reactor Kashiwazaki-Kariwa nuclear plant, the largest nuclear power station in Japan.
His parents and other relatives live in the coastal city.
The Diet’s Fukushima Nuclear Accident Independent Investigation Commission also pointed out TEPCO’s propensity to seek cozy ties with regulating bodies.
In its report published in 2012, the commission denounced collusion between TEPCO and the government’s nuclear watchdog, describing nuclear authorities as a “regulatory capture” of the company because they were easily manipulated by TEPCO’s vast wealth of nuclear expertise.
In his new book, Hasuike describes, for example, TEPCO’s moves related to the No. 6 and No. 7 reactors at the Kashiwazaki-Kariwa plant.
The company is currently seeking to bring those reactors back online as soon as possible to save on fuel costs needed to operate its thermal plants.
Hasuike said in the book that TEPCO sent some of its employees to the then Science and Technology Agency in 1990 on the pretext of “assisting in preparations” for a public hearing planned by the government’s Nuclear Safety Commission.
The agency’s commission was scheduled to hold a public hearing at the Niigata prefectural government building on whether to give approval and licenses for the construction of the No. 6 and No. 7 reactors at the Kashiwazaki-Kariwa plant.
The TEPCO employees were sent to the agency, where the commission’s secretariat was located, to check postcards sent by those hoping to attend the hearing. Specifically, TEPCO wanted to know their stance on nuclear energy and prevent the hearing from being dominated by anti-nuclear attendees, according to the book.
When they grasped the number of nuclear opponents who planned to attend, the TEPCO employees made arrangements to send several times that number of application postcards to the pro-nuclear energy camp to ensure their representation was larger than nuclear skeptics at the hearing, Hasuike wrote.
After the applicants were selected and those permitted to ask questions at the hearing were chosen, the TEPCO employees advised the pro-nuclear attendees on their proposed questions with the aim to make the plant look safe, according to the book.
Hasuike has also been known as a relentless critic of the government for its handling of the decades-old issue of Japanese nationals abducted by North Korean agents. He has appeared on TV programs and written several books on the subject.
His younger brother, Kaoru, returned to Japan in 2002 after being abducted to North Korea in 1978. But many other abductees remain unaccounted for, and there are few signs of progress toward a resolution of the issue.
People are helped into a Maritime Self-Defense Force helicopter as part a two-day evacuation drill for multiple nuclear accidents in Oi, Fukui Prefecture, on Saturday.
Aug 26, 2018
FUKUI – A nuclear disaster drill for simultaneous accidents at the Oi and Takahama nuclear power plants in Fukui Prefecture ended Sunday after mobilizing 21,000 people.
It was the first disaster response drill designed for serious simultaneous accidents at multiple plants since the Fukushima nuclear crisis in March 2011.
The drill involved about 21,000 people including residents and officials from the Cabinet Office, the Nuclear Regulation Authority and municipal governments.
Sunday’s exercise focused on evacuating residents from Fukui and surrounding prefectures. It also involved personnel aboard the Maritime Self-Defense Force minesweeper tender Bungo, which was deployed to provide first aid to “injured” participants who were ferried there by helicopter.
In the town of Takahama, 20 residents were flown to Osaka on a Ground Self-Defense Force CH-47J chopper and bused to Sanda in Hyogo on the assumption that a evacuation route was cut off by a landslide.
Preparations involving the Oi and Takahama plants, both managed by Kansai Electric Power Co., are deemed necessary as they are just 13.5 km away from each other.
The exercise assumed radioactive substances were released after an earthquake in northern Kyoto knocked out the cooling systems of the two plants’ reactors.
As part of the drill, task forces created at the two plants’ off-site emergency response centers were integrated into Oi’s task force.
Katsunori Yamamoto, 64, who runs a nursing home 5 km from the Takahama plant, played one of his residents. He was evacuated to Tsuruga by a wheelchair-accessible van driven by a Kansai Electric worker.
“I want to assess risks to our nursing home residents,” he said.
An emergency drill at Tokyo Electric Power Co.’s Kashiwazaki-Kariwa nuclear plant in Niigata Prefecture
August 22, 2018
The government’s nuclear watchdog slammed Tokyo Electric Power Co.’s efforts as “unacceptable” in communicating with nuclear authorities during an emergency drill held at its Kashiwazaki-Kariwa nuclear plant.
TEPCO, operator of the crippled Fukushima No. 1 nuclear power plant, was among three utilities to receive the lowest of the three-level scores in terms of ability to share information expediently and accurately, the Nuclear Regulation Authority said July 25.
It was the first time for the company to be given the lowest score on communication skills in a yearly drill.
“It is unacceptable that TEPCO received a low rating, given that it was responsible for the Fukushima disaster,” an NRA official said. “TEPCO appears to be too compartmentalized for its relevant sections to work together and share information.”
The NRA is set to instruct the company to hold additional drills at the plant, which is located in Niigata Prefecture, if it receives another low rating.
The utility was slow in relaying information to the watchdog, and its briefing on its handling of the mock accident was inadequate, according to the NRA’s report.
“We could not respond sufficiently because the envisioned accident was harsh,” said Kiyoto Ishikawa, the chief of the plant’s publicity department, at a news conference.
The drill in question was carried out in March under the scenario of coping with a serious accident.
It involved difficult procedures to cope with a failure in the communication system to send such critical information as the pressure level in the reactors’ containment vessels to the NRA. Operators also simulated a string of maneuvers of the venting system to lower pressure inside the No. 6 reactor that suffered core damage.
“We had to deal with a tough situation because it proceeded with less time allotted for us than in a real accident,” Ishikawa said. “We are determined to make more efforts and improve our standing.”
The NRA’s assessment comes at a time when TEPCO seeks to bring the No. 6 and No. 7 reactors at the Kashiwazaki-Kariwa plant back on line in the near future to save expensive fuel costs incurred by the operation of its thermal power plants.
With seven reactors, the Kashiwazaki-Kariwa plant is the largest in Japan. It is the only nuclear complex for TEPCO to turn to as it proceeds with decommissioning of the Fukushima No. 1 and No. 2 nuclear plants.
The two reactors have cleared the screenings by the NRA under the stricter reactor regulations put in place following the 2011 Fukushima triple meltdown.
The other plants that were rated on par with the Kashiwazaki-Kariwa plant in the evaluation of emergency drills were Hokuriku Electric Power Co.’s Shika plant in Ishikawa Prefecture and Chubu Electric Power Co.’s Hamaoka plant in Shizuoka Prefecture.
In the case of the Shika plant, Hokuriku Electric’s in-house information sharing system got bogged down, making it impossible for the NRA to remain in the communication loop.
In total, 10 operators of nuclear power plants carried out emergency drills.
The NRA considers it vital for the operator of a nuclear plant to share accurate information on the accident since the prime minister declares a “nuclear emergency” based on the NRA’s report.
In the Fukushima disaster, TEPCO had trouble passing on information on the unfolding nuclear crisis with the government swiftly and accurately, resulting in confusion.
Tokyo Electric Power Co.’s Fukushima No. 2 nuclear plant
August 22, 2018
Tokyo Electric Power Co. Holdings Inc., operator of the crippled Fukushima No. 1 nuclear power plant, has begun talks with the nuclear industry’s key players about a possible tie-up for maintenance and management services and decommissioning of reactors.
The company is in discussions with Chubu Electric Power Co., Hitachi Ltd. and Toshiba Corp., according to sources.
If the talks go well, a consolidation of the nuclear industry could be in the cards, the sources said.
TEPCO seeks to restart two of the seven reactors at its Kashiwazaki-Kariwa plant in Niigata Prefecture in the near future. Both are boiling water reactors, the same type as those that are to be decommissioned at the Fukushima No. 1 nuclear plant.
TEPCO operates 11 boiling water reactors, seven of which are located at the Kashiwazaki-Kariwa plant. The remainder are located at the Fukushima No. 2 nuclear plant.
However, the utility announced in June it would pull the plug on the Fukushima No. 2 nuclear plant, which suffered damage in the 2011 Great East Japan Earthquake and tsunami and narrowly escaped a serious disaster like at its sister plant.
Chubu Electric also operates three boiling water reactors at its Hamaoka nuclear plant in Shizuoka Prefecture. The plant’s two other reactors are in the process of decommissioning.
Hitachi and Toshiba were both involved in the design and construction of those reactors.
The four parties seek to streamline their nuclear energy operations through cooperation in maintenance and management services as well as safety management of their facilities after the restarts of their reactors.
Utilities today face an exceedingly higher price tag for bolstering safety precautions at their plants that are required under the stricter new reactor regulations put in place in the wake of the 2011 Fukushima No. 1 disaster.
With none of their reactors back online, TEPCO and Chubu Electric fell behind other utilities.
Kansai Electric Power Co. and other operators of pressurized water reactors have restarted their plants.
Meanwhile, work to decommission reactors is looming large for TEPCO and other utilities, as many reactors are aging and nearing their 40-year life span.
The four companies are also expected to discuss possible construction of new nuclear plants in the coming years.
TEPCO plans to call on other electric power companies to join a consortium it seeks to set up in fiscal 2020 in connection with its project to construct the Higashidori nuclear plant in Aomori Prefecture. The construction of the facility has been suspended since the quake and tsunami.
