Japanese regulator bans nuclear plant restart over lax safeguards


The operator of the Fukushima nuclear plant that was destroyed in a 2011 disaster said Wednesday it will accept a penalty imposed by regulators over sloppy anti-terrorism measures at another nuclear plant it runs, a step that will prevent its desperately sought restart of the facility for at least a year.

Tokyo Electric Power Co (TEPCO) made the announcement in response to a decision by the Nuclear Regulation Authority in late March to ban it from moving any nuclear materials at the No. 7 reactor at the Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture. The measure will suspend all ongoing steps to restart the plant.

Regulators found malfunctioning anti-terrorism equipment and inadequate protection of nuclear materials at multiple locations at the plant from at least 2018. The chairman of the authority, Toyoshi Fuketa, says TEPCO has since restored the safety functions, but the problems were deemed serious and systematic.

The punishment will be officially issued at a regulatory commission meeting next week, he said.

The plant was partially damaged in a 2007 earthquake, causing mistrust among local municipalities. It has been offline since 2012. Of the 54 nuclear reactors Japan used to have, nine have been restarted under tougher post-Fukushima safety standards and four are currently operating.

The authority gave the Kashiwazaki-Kariwa plant’s nuclear security a “red” rating, meaning its management had deteriorated to levels that could allow intruders. It was the first time a Japanese nuclear operator was given that rating.

“I hope TEPCO will make efforts to analyze the problem ... and fully cooperate with our inspections,” Fuketa said, adding that TEPCO's ability to keep its license to operate the plant depends on the results of upcoming checks.

TEPCO’s president, Tomoaki Kobayakawa, apologized for causing safety concerns and said he and three other company executives are taking 30% salary cuts for six months.

“We take the problem seriously and will investigate the cause and pursue efforts to make drastic reforms,” he told reporters.

The case raised questions about whether TEPCO has fully learned lessons from the 2011 Fukushima disaster, which was triggered by a massive earthquake and tsunami but has been largely attributed to the utility’s lack of a safety culture.

Critics say the Kashiwazaki-Kariwa plant requires higher security because it is located on the coast facing North Korea.

The punishment comes as TEPCO was making final preparations to restart the plant after regulators granted safety approvals for its No. 6 and No. 7 reactors in 2017. Restarting the two reactors is considered crucial for TEPCO to reduce its financial burden in paying for damage caused by the Fukushima disaster.

The penalty does not affect the wrecked Fukushima plant, which is being decommissioned. On Wednesday, Prime Minister Yoshihide Suga said he will make a final decision “within days” on whether to allow the release into the sea of massive amounts of treated but still radioactive water stored at the plant. TEPCO is expected to run out of storage space for the water in the fall of 2022.

Japan Fisheries Cooperatives Chairman Hiroshi Kishi rejected Suga’s explanation that the release into the sea is the most realistic option, and demanded the government explain how it will address damage caused to the local fishing industry. TEPCO and government officials say radionuclides can be filtered to allowable safety levels, but some experts say the impact on marine life from long-term, low-dose exposure is still unknown.

TEPCO acknowledged in January that there was an unauthorized use of an identification card by a worker to enter sensitive areas at the Kashiwazaki-Kariwa plant last September, along with other key safety shortcomings.

Sloppy anti-terrorism measures. Whew, can't say anymore than that. And while this is going on, Suga and Kishi met with the Fisheries cooperative chairman to discuss releasing contaminated water into the ocean. LDP and TEPCO are a real pair.

This sentence makes no sense.....

Of the 54 nuclear reactors Japan used to have, nine have been restarted under tougher post-Fukushima safety standards and four are currently operating.

So the other 5 restarted and shut down again?

0 ( +1 / -1 )

KEPCO restarted their reactors but had to shut them again for not meeting anti terrorist measures.

Fukushima is a nuclear disaster not a plant being decommissioned.

TEPCO should not be in the business of nuclear energy.

The 'ban' is only a one-year blocking move to allow TEPCO extra time to do something more appealing.

Powsurfer, the 'other five' will be offline for mandated regular inspections which take big chunks of time.

30% cut of a very large salary for 6 months still leaves a large salary for 6 months - meaningless gesture.

Yet nothing has happen. That's good. But a bit scary.

Radioactive water. As one moves up the food chain, the concentration of radionuclides increases. Imagine that. Consumption of the bounty from the sea, thus becomes a health hazard.

I am very pronuclear as one of the options necessary to stop fossil fuel dependency, but nuclear power depends very strongly on safety, consequences of lack of safety mechanisms are too strong and long lasting, so I completely agree with a ban based on this reason.

How come energy companies have not learnt their lesson?

2 ( +2 / -0 )

Japanese authorities and Tepco try to release contaminated water including radioactivity such as radioactive iodine or strontium90 to Pacific ocean on the pretext of no places where they put new tanks.

But they only chose cheaper way than buying new places and making new radioactivity tanks.

TEPCO is the type of company that operates REACTIVLY, and NOT PROACTIVELY. This operator must be changed and replaced with a company that will act on it's own proactively and not wait for the inspectors to fix and correct it's screw ups.

"Lax safeguards?", those turkeys did not learn anything from what happen 10 years ago. That is scary.
