TOKYO (Reuters) - Japan's Kansai Electric Power Co said on Saturday it planned to manually shut down the No.1 reactor at its Ohi nuclear power plant in western Japan due to technical glitches, but that no radiation leakage had occurred.
The reactor, located 350 km (220 miles) west of Tokyo, will be closed for checks after pressure in a tank containing boric acid water fell for a time on Friday night for unknown reasons, a Kansai Electric spokesman said.
The pressure has since come back up to the normal range.
The shutdown will further compound a tight power supply linked to long-running attempts to resolve the radiation crisis at Tokyo Electric Power Co's Fukushima Daiichi nuclear power plant, hit by the March 11 earthquake and tsunami. Power difficulties are stifling manufacturing activity and hurting Japan's weak economy.
The Trade Ministry said the reactor would be shut down at 9 p.m. (1200 GMT).
