Shikoku Electric Power Co on Monday announced the results of stress tests on a suspended nuclear reactor at its Ikata plant in Ehime Prefecture. The utility handed the report to the Nuclear and Industrial Safety Agency, which is overseen by the Economy, Trade and Industry Ministry.
According to NHK, the report says the No. 3 reactor can withstand an earthquake 1.86 times the strongest assumed level of 570 gals. It also said that the plant would be able to withstand tsunami waves as high as 14.2 meters.
The report is the second one to be submitted on the results of stress tests following Kansai Electric Power Co, which conducted tests on its Oi nuclear power plant in Fukui Prefecture in October.
In July, the government ordered utility companies to conduct the stress tests on all the country's nuclear plants to ease heightened concerns about disaster preparedness.
The March 11 earthquake and tsunami in northeastern Japan knocked out power at the Fukushima Daiichi nuclear power plant, sending it toward meltdown in a crisis that engineers are still struggling to contain. The plant operator, Tokyo Electric Power Co, has come under heavy criticism for failing to sufficiently prepare for the disasters.
More than two-thirds of Japan's 54 reactors remain offline. Utilities with plants that were shut down for safety reviews after the crisis or that already had been offline due to routine maintenance have been reluctant to restart them because of public anxiety and anti-nuclear protests.
The stress tests incorporate elements from those ordered by the European Union on the 143 nuclear plants in that region after the Fukushima crisis.
Those reviews, which started June 1, are supposed to consider the impact of both natural and man-made events such as airplane crashes and terrorist attacks.
