Glitch halts nuclear reactor in Japan days after restart

A Japanese utility on Monday said that a glitch switched off a nuclear reactor just days after it was turned on again after a nationwide shutdown following the 2011 Fukushima crisis.

Kansai Electric Power had been planning to start generating electricity on Monday from its No. 4 reactor at the Takahama plant, 380 kilometers west of Tokyo.

But the reactor unexpectedly shut down on Monday afternoon after the restart began on Friday, marking the first major technical problem for a restart since Tokyo approved switching on sites considered safe.
