Nearly half of Japan’s commercial nuclear power reactors had problems requiring action, including the need for inspections, in their fiscal 2009 operations, the Nuclear and Industrial Safety Agency said Monday in its first such report. But none is deemed to have had a problem that is not “tolerable,” while a majority got a passing grade, the agency affiliated with the Ministry of Economy, Trade and Industry said in “report cards” on problems, malfunctions and operational status at the nation’s 54 reactors in the year through March 31.
Fourteen of Tokyo Electric Power Co.’s 17 reactors needed additional inspections, with the No. 1 to 4 reactors of the Fukushima No. 2 plant judged to have had “significant” problems over a discharge of radioactive materials into the sea through a drainage pipe that came to light in October. The agency compiles inspection plans for the next fiscal year based on the latest evaluations. Those getting a passing grade will have to undergo only basic inspections, but additional inspections or administrative measures will be imposed on others found to be problematic.
