A spent fuel pool is seen inside the No. 3 reactor of TEPCO's Kashiwazaki-Kariwa nuclear power plant in Kashiwazaki, Japan July 28, 2007. The TEPCO's quake-hit nuclear power plant -- the world's largest nuclear power plant -- could take longer than a year to resume operations if defects are found in key safety devices, media quoted an expert set to head an investigation team as saying.
