Fukushima investigation reveals failings
Japan’s response to the nuclear crisis that followed the tsunami in March was confused and riddled with problems, including an erroneous assumption that an emergency cooling system was working and a delay in disclosing dangerous radiation leaks, a report has revealed.
The disturbing picture of harried and bumbling workers and government officials scrambling to respond to the problems at the Fukushima Daiichi nuclear power plant was depicted in the report, detailing a government investigation.
The 507-page interim report, compiled by interviewing more than 400 people, including utility workers and government officials, found authorities had grossly underestimated tsunami risks, assuming the highest wave would be six metres (20ft). The tsunami hit at more than double that level.
The report criticised the use of the term soteigai, meaning outside our imagination, or unforseeable, which it said implied authorities were shirking responsibility for what had happened. It said by labelling the events as beyond what could have been expected, officials had invited public distrust.
“This accident has taught us an important lesson on how we must be ready for soteigai,” it said.
