In their first meeting since Japan created a new, more independent nuclear agency 13 months ago, the top regulator yesterday urged the head of the utility that runs the crippled Fukushima Dai-ichi nuclear power plant to take “drastic steps” to mitigate a spate of mishaps at the complex.
Nuclear Regulation Authority Chairman Shunichi Tanaka summoned Tokyo Electric Power Co (TEPCO) president Naomi Hirose to his office to express concerns about growing problems at the plant, including human errors that have led to a series of leaks of contaminated water used to cool the damaged reactors.
Human error is mostly to blame for the recent mishaps, as workers deal with a string of crises. Tanaka said earlier this month the repeated “silly mistakes” are a sign of declining morale and sense of responsibility. TEPCO acknowledged a systemic problem in a recent report: Workers under tight deadlines tend to cut corners, making mistakes more likely; at times, they do not fully understand their assignment or procedures.
Hirose acknowledged that TEPCO is having trouble finding a stable pool of workers at the plant, but promised to send more staff from other locations to Fukushima Dai-ichi, where three reactors melted down after the March 2011 earthquake and tsunami.
It was the first time Tanaka met with a utility president, in part because of his attempt to counter criticism that the previous nuclear regulator, which was under the wing of the trade and industry ministry, was too close to the sector.
Such criticism contributed to the creation last year of a separate, independent nuclear regulator that Tanaka now heads.
Agency officials said the meeting indicated Tanaka’s grave concerns. Tanaka and other commissioners have said they plan to step forward to provide more proactive instructions in the future.
He told Hirose that resolving the problems requires “drastic steps” with a long-term vision, not procedural or manual changes as TEPCO has suggested, Katsuhiko Ikeda, administrative head of the agency, told reporters after the talks which he also attended. The meeting was closed except for few minutes at the beginning.
Masashi Goto, a nuclear reactor engineer and lecturer at Meiji University, was skeptical about how effective the meeting would be.
“What matters is what they really talked about,” he said. “To me it seems the regulatory side was just trying to smooth things out and make it look the situation should start improving.”
Tanaka also urged the plant to do more to reduce radioactivity at the site to allow workers to work without full-face masks, which add to hard working conditions.
