February 16, 2021
TSURUGA, Fukui — The mayor of a central Japan town hosting a nuclear power plant operated by Kansai Electric Power Co. informed the speaker of the municipal assembly on Feb. 15 that he would approve the restart of a reactor at the plant that is more than 40 years old.
Mayor Hideki Toshima of the Fukui Prefecture town of Mihama told Mihama Municipal Assembly Speaker Yoshihiro Takenaka that he would approve the restart of the No. 3 reactor at Mihama Nuclear Power Station, which began operating in the 1970s. The assembly had already approved the reactivation of the aging reactor.
Meanwhile, Mayor Yutaka Nose of the prefectural town of Takahama, home to Kansai Electric’s Takahama Nuclear Power Station, whose No. 1 and 2 reactors are also over 40 years old, has given the green light for resuming the operations of the two rectors, while the Takahama Municipal Assembly has also approved of the move.
Now that local consent has been secured, the focus has shifted to the decisions expected from Gov. Tatsuji Sugimoto and the prefectural assembly.
The Mihama plant’s No. 3 reactor went online in December 1976. In response to the meltdowns at Tokyo Electric Power Co.’s Fukushima Daiichi Nuclear Power Station following the March 2011 Great East Japan Earthquake and tsunami, the Japanese government limited the operational life of nuclear reactors to “40 years in principle” in July 2013, while allowing a one-time extension of up to 20 years if the reactor fulfilled safety standards. The No. 3 reactor at the Mihama power station, along with the No. 1 and No. 2 rectors at the Takahama plant, have passed screening by the Nuclear Regulation Authority.
Mayor Toshima said on Feb. 15 that conditions to approve the restart “have all been met, including understanding from the townspeople and consent from the municipal assembly, as well as promising feedback over regional development by the central government and Kansai Electric.” He added, “Both supporters and skeptics of the reactor restart are concerned about its safety. I will make sure to pay attention to the process.”
Toshima had spoken with Economy, Trade and Industry Minister Hiroshi Kajiyama online three days prior. He had then expressed his intension to approve the reactivation, saying that the central government had given him positive responses about regional development and other measures he had requested.
As a general rule, a nuclear power plant operator is expected to obtain consent for restarting a rector from the local governments around the plant as well as local assemblies. As a condition for approving the restart, the Fukui Prefectural Government said Kansai Electric would need to present candidate sites outside the prefecture for interim spent nuclear fuel storage facilities. The prefectural government maintained that until that condition was achieved, the parties were “not even at the starting line of discussion.”
However, after Kansai Electric proposed on Feb. 12 that it would finalize a planned site for the storage facilities by the end of 2023, the prefectural government demonstrated a positive attitude toward reactivation. Discussion on restarting the aging reactor may develop further at the prefectural assembly session convening on Feb. 16.

Tsunami-hit Onagawa reactor in northeast Japan gets final approval to restart
November 12, 2020
Sendai – A nuclear reactor in Miyagi Prefecture damaged by the Great East Japan Earthquake and tsunami disaster in 2011 has cleared the last hurdle to resume operations, getting the green light Wednesday from local officials.
The No. 2 unit of Tohoku Electric Power Co.’s Onagawa plant is the first of the reactors damaged in the disaster to win final approval with local consent to restart.
Miyagi Gov. Yoshihiro Murai and the mayors of Onagawa and Ishinomaki, the two municipalities that host the unit, gave their consent at a meeting after the plant cleared national safety screening in February.
“There is an excellent, stable supply of electricity in a nuclear plant, and the plant can also contribute to the local economy,” Murai said during a news conference after the meeting in Ishinomaki.
A Tohoku Electric official said the utility will “continue to do its best to ensure safety” in plant operations.
Tohoku Electric says it plans to restart the No. 2 reactor in fiscal 2022 at the earliest after work on safety and disaster prevention measures is completed, such as the construction of an 800-meter-long seawall at the plant.
The Onagawa plant is the closest nuclear plant to the epicenter of the magnitude-9.0 earthquake that struck nine years ago.
The central government has been pushing for the reactor to be reactivated so as to ensure a stable power supply, with trade minister Hiroshi Kajiyama seeking Murai’s consent in March.
In Tokyo, Chief Cabinet Secretary Katsunobu Kato said during a news conference that gaining local consent marks an “important” step.
The municipal assemblies for Onagawa and Ishinomaki had already given their consent, as had the prefectural assembly. On Monday, the leaders of most of Miyagi’s 35 municipalities agreed at a meeting to support the decisions of Onagawa and Ishinomaki.
Part of the reason for local approval is the money generated by hosting the reactor, with Onagawa having received from the central government around ¥27 billion ($256 million) in grants in the past, as well as hefty property taxes from Tohoku Electric.
Masanori Takahashi, chairman of the town’s chamber of commerce lobbying local leaders to support the restart, said, “We are getting closer to the end of disaster-linked infrastructure development projects,” adding it is now “absolutely necessary to restart the reactor to get the town’s economy going.”
Some local residents, however, believe the approval was rushed, saying concerns linger over whether evacuation plans can actually be implemented in the event of a nuclear accident.
The 825,000-kilowatt boiling water reactor won approval to restart from the Nuclear Regulation Authority earlier this year, becoming the second disaster-damaged reactor to pass stricter safety standards put in place after the Fukushima nuclear disaster.
A massive earthquake and subsequent tsunami hit northeastern Japan on March 11, 2011, triggering one of the worst nuclear disasters since the 1986 Chernobyl accident in Fukushima Prefecture, which is adjacent to Miyagi.
At one point, the disaster caused all of Japan’s 54 reactors to be brought to a halt. So far, nine units at five plants in the country have restarted following regulatory and local approval.
At the Onagawa complex, all three reactors — the same boiling water reactors as were used at the Fukushima No. 1 plant run by Tokyo Electric Power Company Holdings Inc. — shut down but the underground floors of the No. 2 unit were flooded, after the facility was hit by a tsunami of up to 13 meters.
In Onagawa, more than 800 people were listed as killed or missing.
As the plant’s emergency cooling system functioned normally, there was no meltdown of the type that occurred at three of the six reactors at the Fukushima No. 1 plant.
The utility has decided to decommission the reactor’s No. 1 unit, and is considering whether to request a review by the authority to restart the No. 3 unit.
Other boiling water reactors at sites including the Tokai No. 2 plant of Japan Atomic Power Co. in Ibaraki Prefecture have also won the regulator’s approval to resume operations, but have yet to obtain local consent.

Approval given for 1st restart of nuclear plant damaged in 3/11
November 12, 2020
SENDAI, Miyagi Prefecture–Citing expected economic benefits, local governments approved the first restart of a nuclear power plant damaged in the 2011 Great East Japan Earthquake and tsunami.
Miyagi Governor Yoshihiro Murai on Nov. 11 said the decision on resuming operations of the No. 2 reactor at the Onagawa nuclear plant was “not an easy one.”
Required safety measures must still be completed at the plant, and questions remain about the evacuation route that will be used in the event of a disaster at the plant, which straddles the municipalities of Onagawa and Ishinomaki on the Pacific coast.
However, residents near the nuclear plant have requested a resumption of nuclear power operations to revive their depleted communities.
“We can expect many jobs to be created if the nuclear plant resumes operations,” Murai said. “Municipalities hosting the plant will also have increased tax revenues through the restart of the plant in terms of fixed property tax and nuclear fuel tax.”
His announcement followed a meeting with the mayors of Onagawa and Ishinomaki earlier in the day, in which the governor confirmed their approval of the planned restart.
Tohoku Electric Power Co., operator of the Onagawa plant, needed the consent from the host communities as well as Miyagi Prefecture although it is not a legal mandate.
The utility expects the reactor, with an output capacity of 825 megawatts, to be brought online as early as in 2023, when it plans to complete an array of projects designed to strengthen the safety of the plant.
“A critical decision was made as we are aiming at a restart,” the utility said in a statement about Murai’s announcement. “We are determined to strive in full force to enhance safety features of the facility.”
If restarted, the No. 2 unit will be the first boiling water reactor in Japan brought online since the 2011 nuclear disaster. The reactors at the Fukushima No. 1 nuclear plant, which suffered a triple meltdown after being swamped by the tsunami, are also boiling water types.
All reactors in Japan were shut down after the Fukushima nuclear disaster. Since then, nine reactors at five nuclear plants have resumed operations. They were all pressurized water reactors located in western Japan.
When the 13.0-meter tsunami hit the Onagawa plant after the Great East Japan Earthquake, the No. 2 reactor building was just high enough to escape the water.
Still, part of the equipment to cool the reactor failed, and more than 1,000 cracks were discovered in the reactor building.
The Onagawa plant has two other reactors. Tohoku Electric decided to retire the No. 1 reactor, but it is preparing to apply for a restart of the No. 3 reactor.
The utility compiled a set of safeguards for resuming operations of the No. 2 reactor, including construction of a 29-meter-high sea wall as protection against tsunami.
In February, the Nuclear Regulation Authority, the government nuclear watchdog, certified the No. 2 reactor as meeting the more stringent reactor regulations put in place after the Fukushima disaster.
The following month, industry minister Hiroshi Kajiyama urged Murai to agree to the restart of the Onagawa plant.
Japan had 54 nuclear reactors before the disaster struck in the Tohoku region.
Since the Fukushima accident, the number has fallen to 33, as other reactors were retired.
The central government needs to bring around 30 reactors online to achieve its target of nuclear energy representing 20 to 22 percent of the nation’s overall energy output in fiscal 2030.
The government hopes the restart of the Onagawa nuclear plant will prompt other municipalities that host boiling water reactors to accept a resumption of their operations.

Restart of Japan’s tsunami-hit Onagawa nuclear reactor to be OK’d
October 14, 2020
Sendai – A nuclear reactor in northeastern Japan damaged by the 2011 earthquake-tsunami disaster is all but certain to resume operations as the governor of the prefecture hosting the facility has decided to give consent, local officials said Wednesday.
For the No. 2 unit of the Onagawa nuclear plant in Miyagi Prefecture to restart, winning consent from local government leaders is the last remaining step needed after it cleared a national safety screening in February.

Miyagi Gov. Yoshihiro Murai will formally announce his consent by the end of the year, according to the officials, who spoke on condition of anonymity.
By doing so, he would be the first governor of a disaster-hit prefecture to give the green light to the restart of a nuclear reactor.
The other heads of local governments whose consent is essential are the mayors of the city of Ishinomaki and the town of Onagawa where the plant operated by Tohoku Electric Power Co. straddles.
Of them, Ishinomaki Mayor Hiroshi Kameyama has already expressed his willingness to give the nod, and such a move is backed by the two municipalities’ assemblies.
After the quake triggered one of the world’s worst nuclear crises in neighboring Fukushima Prefecture and caused all of Japan’s 54 reactors to halt at one point, nine units at five plants in the country have restarted following regulatory and local approval.
Murai has come to believe residents will support his stance after the prefectural assembly adopted a plea seeking his consent at a panel meeting Tuesday and is set to approve it at a plenary session next week, the officials said.
“When the plenary session shows its stance, I will make a decision upon hearing the opinions of mayors of cities, towns and villages within the prefecture,” Murai said.
The 825,000-kilowatt reactor won the approval of the Nuclear Regulation Authority in February, becoming the second disaster-damaged reactor to pass stricter safety standards after the Fukushima nuclear disaster — the worst since the 1986 Chernobyl accident.
At the Onagawa complex, all three reactors — the same boiling water reactors as in Fukushima — shut down when a massive quake and a 13-meter tsunami hit northeastern Japan on March 11, 2011, flooding the underground floors of the No. 2 unit.
However, the plant’s emergency cooling system did not fail and there was no meltdown of the type that occurred at three of the six reactors at the Fukushima Daiichi plant of Tokyo Electric Power Company Holdings Inc.
Tohoku Electric Power Co. aims to restart the Onagawa No. 2 reactor in 2022 at the earliest, after completing anti-disaster work such as the construction of an 800-meter-long seawall at the plant. It has already decided to scrap the No. 1 unit.
Other boiling water reactors at TEPCO’s Kashiwazaki-Kariwa plant in Niigata Prefecture and the Tokai No. 2 plant of Japan Atomic Power Co. in Ibaraki Prefecture have also won the regulator’s approval to resume operations but have yet to obtain local consent.
Tohoku reactor restart: What is the state of Japan’s nuclear policy?
Their contempt for the Japanese’ public’s will and the health and well being of people, animals, plants, oceans, rivers, lakes, genetic pools and the economies of the northern hemisphere is appalling. Abe, LDP, nuke industry, anyone that’s pro-nuke.’

Dec 9, 2019
OSAKA – In late November, the Nuclear Regulation Authority (NRA) gave the green light for restarting the No. 2 reactor at Tohoku Electric Power Co.’s Onagawa plant in Miyagi Prefecture, which had been damaged in the March 11, 2011, earthquake and tsunami. The announcement once again put the spotlight on the country’s nuclear power policy, not only in Tohoku but nationwide.
Why did the Onagawa restart attract so much attention?
While the Onagawa plant is actually the second damaged on 3/11, after the Tokai No. 2 power station in Ibaraki Prefecture, to pass the NRA’s new safety regulations for nuclear power plants prepared after the disaster, it happens to be the nuclear plant closest to the epicenter of the magnitude 9 quake that struck off the Tohoku coast that day.
The Onagawa facility is located near Ishinomaki, which received extensive damage and much domestic and international media attention after the tsunami claimed the lives of 74 Okawa Elementary School students.
In addition, the Onagawa reactor, which was flooded on 3/11, is the first boiling water reactor to have its restart application approved by the NRA.
There are three kinds of nuclear reactors in operation in Japan: 14 pressured water reactors (PWRs), four advanced boiling water reactors (ABWRs) and 13 boiling water reactors (BWRs), which are the same kind as those at the Fukushima No. 1 plant destroyed by the 3/11 quake and tsunami. The PWRs are considered more technologically stable than the other kinds, and have a better ability to contain radiation.
Now that the NRA has greenlighted Onagawa’s restart, does that mean it will happen anytime soon?
That depends on a number of factors. The Onagawa plant is not ready to be fired up tomorrow. It must first complete the installation of various anti-disaster measures, including a 29-meter-high, 800-meter-long seawall along the Pacific coast to guard against tsunami as high as 23.1 meters. That will not be completed until sometime in fiscal 2020, which begins April 1.
Furthermore, various local governments, including Ishinomaki and Miyagi Prefecture, will have to give their consent to the restart. That could involve long, drawn out negotiations between the utility and local residents and politicians. It’s also probable that lawyers and local citizens opposed to a restart will seek a court injunction to halt the move based on safety concerns. If a court approves an injunction, that will create further delays.
How many other nuclear power plants are there and what are their statuses?
As of this month, there are nine reactors officially in operation. Four belong to Kansai Electric Power Co. (Kepco), which provides electricity mainly to Kyoto, Osaka, Nara, Hyogo, Shiga and Wakayama prefectures. Another four belong to Kyushu Electric Power Co. One of Shikoku Electric Power Co.’s reactors at its Ikata plant is also operating.
Another six reactors have made improvements to meet the new, post-3/11 quake safety standards and have received NRA approval to restart. These include two reactors at Tokyo Electric Power Company Holdings’ Kashiwazaki-Kariwa plant in Niigata Prefecture, two of the four reactors at Kepco’s Takahama plant (the other two are in operation) in Fukui Prefecture, one reactor at Kepco’s Mihama plant (the other two have been decommissioned), also in Fukui Prefecture, and one reactor at Japan Atomic Power Co.’s Tokai No. 2 plant in Ibaraki Prefecture. The other reactor at the facility has been decommissioned.
Nearly a dozen reactors are now in the process of undergoing safety reviews and will have to upgrade their facilities to meet tougher NRA standards for disaster preparedness, and then, if they receive approval to restart, will go through the process of obtaining local consent.
These include reactors in Hokkaido, Aomori, Shizuoka, Ishikawa, Fukui and Shimane prefectures.
Finally, another nine reactors have not applied to be restarted under the new regulations, and 24 reactors, including all six Fukushima No. 1 plant reactors and all four Fukushima No. 2 plant reactors, as well as four of Kepco’s 11 reactors in Fukui Prefecture, are being decommissioned.
How much electricity does nuclear power provide?
Figures vary, sometimes greatly, depending on how many plants in operation were shut down for inspection during a particular year. The latest figures from the Ministry of Economy, Trade and Industry’s Agency for Natural Resources show that in 2017, nuclear power provided 3.1 percent of Japan’s electricity. The Institute for Sustainable Energy Policies, a nonprofit research institute, estimates that based on its own surveys of utilities, nuclear provided 4.7 percent of Japan’s electricity last year.
What about the future for nuclear power in Japan?
The government’s long-term energy policy for 2030 calls for nuclear power to make up around 20 to 22 percent of the nation’s energy mix, and it is pushing hard for the restart of as many idled reactors as possible. By then, the plan calls for renewable energy to account for 22 to 24 percent of the mix, LNG to make up 27 percent, coal 26 percent and oil 3 percent.
But the obstacles to restarting, or continuing to operate, nuclear plants in the coming years are vast. In addition to local opposition that could delay restarts for months or years, costing the utilities money, they include such issues as the economics of running reactors past 40 years, for which the utilities must first spend money to upgrade their facilities in order to meet new NRA standards regarding reactors older than four decades.
While Kepco has secured permission to operate three reactors already over 40 years old for another two decades at the most, other utilities with reactors currently more than 30 years old — such as Tepco’s Kashiwazaki-Kariwa No. 1 reactor (34 years old) — will have to decide within a few years whether it’s worth the investment of money and time to apply for a two-decade extension or whether it’s cheaper to decommission.
A second problem has to do with spent nuclear fuel generated by the restarted reactors.
Tokyo is making efforts to find local governments able and willing to have a midterm spent fuel storage facility built in their backyard, and has agreed to offer financial incentives for anyone willing to accept a facility. No luck so far. Meanwhile, in Fukui Prefecture, which has the largest concentration of reactors (13 commercial reactors plus the Monju experimental fast-breeder reactor) in the nation, Gov. Tatsuji Sugimoto is insisting that such storage facilities be built outside the prefecture. His position could lead to other prefectures hosting nuclear power plants to take a firmer stance with utilities and the central government over what to do with spent nuclear fuel when they come seeking local consent for their own restart plans.

Japan’s Nuclear Regulator Not Agreeing to Tepco’s Kashiwazaki-Kariwa NPP Reactor Restart Plans
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.
Sendai Reactor Back Online
Workers in the control room restart reactor 1 at Kyushu Electric Power Co.’s Sendai nuclear plant in Kagoshima Prefecture Thursday night
Sendai reactor goes back online
Operators have powered on a nuclear reactor at a plant in western Japan on Thursday night after 2 months of inspections.
Officials at Kyushu Electric Power Company say workers have begun pulling control rods out of the Number One reactor at their Sendai plant in Kagoshima Prefecture.
The reactor has been offline since October. Before that, it operated for 14 months as the first reactor in the country to go online under new regulations following the Fukushima Daiichi nuclear disaster.
The utility says it found no abnormalities during its regular and special inspections.
The special checks were added at the request of Kagoshima Governor Satoshi Mitazono, who took office in July. He asked the utility to see if strong earthquakes that occurred at nearby Kumamoto Prefecture in April had affected the plant.
Officials say they expect the reactor to reach criticality on Friday and begin transmitting electricity to the grid on Sunday. They also expect the plant to resume commercial operations in early January.
A group opposing the restart held a rally on Thursday outside the facility. Group leader Yoshitaka Mukohara said a proposed prefectural panel should first give a judgment before the reactor is brought online.
Governor Mitazono had promised to set up an expert panel to look into the reactor’s safety, but it has yet to be launched. Mukohara urged the governor to stick to his position.

Kyushu Electric fires up Kagoshima reactor after governor gives OK
FUKUOKA – Kyushu Electric Power Co. restarted a nuclear reactor in Kagoshima Prefecture on Thursday after the prefectural governor, who is opposed to nuclear power, effectively permitted the move last week.
Reactor No. 1 at the Sendai nuclear power complex is one of five reactors to have been reactivated under stricter safety regulations adopted in the wake of the 2011 Fukushima reactor meltdowns. Following resumption in August 2015, its operation had been suspended for a regular checkup since Oct. 6.
The utility pulled out control rods from the reactor at around 9:30 p.m. The reactor is expected to achieve criticality by Friday morning and to start power generation from Sunday. Commercial operation is set to resume from Jan. 6.
Kyushu Electric on Tuesday notified Kagoshima Gov. Satoshi Mitazono of the planned restart of the reactor and was not requested to suspend it this time, it said.
Mitazono, who was elected in July on an anti-nuclear platform, asked the utility in August and September to immediately suspend operation of the plant. Reactor No. 1 came to a halt in October for a regular checkup.
The Sendai complex’s reactor No. 2 is scheduled to be suspended for regular checks from Dec. 16 to Feb. 27.
Mitazono had told the prefectural assembly earlier this month that he had no legal power to decide whether to restart the reactor, paving the way for the latest move.
On Thursday, however, Mitazono said that he will take “strong action, regardless of the reactor’s operation,” if an experts’ committee, which he plans to set up to examine safety at the plant, finds any safety problems.
Some 30 local residents and anti-nuclear group members gathered in front of the Sendai plant Thursday morning to protest the reactivation.
