A worker checks personal radiation gauges on a charging stand at Tokyo Electric Power Co.'s (TEPCO) Kashiwazaki Kariwa nuclear power plant, which is the world's biggest, in Kashiwazaki, November 12, 2012.Tokyo Electronic Power Co will probably have to delay restarting the world's biggest nuclear plant, which is sitting idle in the wake of the Fukushima disaster 20 months ago, further raising costs as the utility spends more on fossil fuels to generate electricity.
