‘Drastic steps’ required at Fukushima plant
Print Edition
In their first meeting since Japan created a new, more independent nuclear agency 13 months ago, the top regulator urged the head of the utility that runs the crippled Fukushima power plant yesterday to take “drastic steps” to mitigate mishaps at the complex.
Nuclear Regulation Authority Chairman Shunichi Tanaka summoned Tokyo Electric Power Co 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 mistakes are 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, saying workers under tight deadlines tend to cut corners, making mistakes more likely, and at times don’t fully understand their assignments 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 sites to Fukushima, where three reactors melted after a March 2011 earthquake and tsunami. TEPCO has acknowledged more than 700 employees have left the company in the last year.
TEPCO Vice President Zengo Aizawa said yesterday the company sees no problem in obtaining workers over the next three years, but uncertainty remains over the long-term decommissioning process.
“We are not sure about our long-term staffing situation during the upcoming process of debris removal, which requires different skills,” Aizawa said. Asked if the company may have to consider hiring foreign workers, he said TEPCO is open to that idea even though it’s not an immediate option.
It was the first time Tanaka has met with a utility president, in part because of his attempt to counter criticism the previous nuclear regulator, which was under the wing of the trade and industry ministry, was too close to the utility sector.
Criticism such as this 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.
Masashi Goto, a nuclear reactor engineer 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 like the situation should start improving.”
