A total of ¥189.2 billion in taxpayers' money has been spent since fiscal 2011 on decommissioning the crippled Fukushima No. 1 nuclear plant and dealing with the buildup of radioactive water there, according to the Board of Audit.
The board also said Monday that Tokyo Electric Power Co. has allocated a massive amount of money for radioactive water treatment facilities and tanks that functioned only for a short period of time, with the amount totaling around ¥68.6 billion.
Tepco has spent some ¥32.1 billion on equipment to remove radioactive cesium from tainted water at the crippled plant, but the facilities stopped operating three months after the start of operations in June 2011, due mainly to equipment failure.
