Fukushima Disaster Caused by “Collusion” Among Government, Regulators and Tepco


Official Investigation Found Earthquake Caused Damage, Reactor Design Dangerous … It Was a “Man-Made” Disaster

Experts have noted for well over a year that the Fukushima reactors were damaged by the earthquakebefore the tsunami hit, showing that the entire GE Mark 1 reactor was fatally defective.

Reuters reports today:

Damage from the huge March 11, 2011, earthquake, and not just the ensuing tsunami, could not be ruled out as a cause of the accident, the panel added, a finding with serious potential implications as Japan seeks to bring idled reactors on line.

The panel’s finding that seismic damage may well have played a role could affect the restart of reactors that were taken offline, mostly for maintenance and safety checks, in the months since Fukushima. Japan is one of the world’s most quake-prone countries.

“We have proved that it cannot be said that there would have been no crisis without the tsunami,” Katsuhiko Ishibashi, a seismologist and panel member, said in the report.

Experts have said that an active fault may lie under Kansai Electric Power Co’s Ohi plant in western Japan, whose No. 3 unit began supplying electricity to the grid early on Thursday. Ohi’s No. 4 unit will come on line later this month after the government approved the restarts to avoid a power shortage.

“This means that all of Japan’s reactors are vulnerable and require retro-fitting, calling into question the hasty decision of the (Prime Minister Yoshihiko) Noda cabinet to restart reactors before getting the lessons of Fukushima,” said Jeffrey Kingston, Asia studies director at Temple University in Tokyo.

This is especially relevant given that the March 2011 earthquake has likely “awakened”  Japanese faults,making another big earthquake more likely.

In addition, independent writers have noted since day one that cost-cutting, cover ups and collusion between the Japanese government and the plant operator were the main causes of the accident.  See this,thisthis and this.

The official Japanese investigation agreed, saying that concluded that collusion was the cause of the disaster. As Reuters notes:

Japan’s Fukushima nuclear crisis was a preventable disaster resulting from “collusion” among the government, regulators and the plant operator, an expert panel said on Thursday, wrapping up an inquiry into the worst nuclear accident in 25 years.

“The … Fukushima Nuclear Power Plant accident was the result of collusion between the government, the regulators and Tepco, and the lack of governance by said parties,” the panel said in an English summary of a 641-page Japanese document.

The report … put an official imprimatur on criticism of the cozy ties that have bound a powerful nexus of interests known as the “nuclear village”.

Regulators, it said, had been reluctant to adopt global safety standards that could have helped prevent the disaster ….

“Across the board, the Commission found ignorance and arrogance unforgivable for anyone or any organization that deals with nuclear power. We found a disregard for global trends and a disregard for public safety,” the panel said.

The report by the experts – one of three panels looking into the Fukushima disaster – follows a six-month investigation involving more than 900 hours of hearings and interviews with more than 1,100 people, the first such inquiry of its kind.

In an effort to repair tattered public trust in the regulatory regime, the government will in a few months set up a more independent nuclear watchdog that will then draft new safety rules.

The report pointed to numerous missed opportunities to take steps to prevent the disaster, citing lobbying by the nuclear power companies as well as a “safety myth” mindset that permeated the industry and the regulatory regime as among the reasons for the failure to be prepared.

As a result of inadequate oversight, the SA (Severe Accident) countermeasures implemented in Japan were practically ineffectivecompared to the countermeasures in place abroad, and actions were significantly delayed as a result,” it said.

Tepco came under heavy criticism in the report, partly for putting cost-cutting steps ahead of safety as nuclear power became less profitable over the years. “While giving lip service to a policy of ‘safety first’, in actuality, safety suffered at the expense of other management priorities,” the team said.

In a report on its internal investigation issued last month, Tepco denied responsibility, saying the big “unforeseen” tsunami was to blame – though it admitted that in hindsight it was insufficiently prepared.

The report stressed that this was a “man-made”, not just natural, disaster.
