Tokyo, Jumada I 20, 1437, February 29, 2016, SPA -- A recently restarted nuclear reactor in western Japan automatically shut down on Monday due to troubles with a generator, local media reported, according to dpa. Kansai Electric Power was investigating the detailed cause of the shutdown at Reactor 4 at the Takahama nuclear plant on the Sea of Japan coast, 400 kilometres west of Tokyo, Jiji Press reported, citing the operator. The utility reactivated the reactor Friday. It was the fourth unit brought back online in Japan under updated regulations following the 2011 nuclear disaster at the Fukushima Daiichi plant. Kansai Electric also resumed the operation of Reactor 3 at the same complex in late January. --SPA 10:48 LOCAL TIME 07:48 GMT www.spa.gov.sa/w
