An employee of Tokyo Electric Power Co. (TEPCO) walks near the entrance gate of the reactor containment vessel at No. 3 reactor of TEPCO's Kashiwazaki-Kariwa nuclear power plant in Kashiwazaki 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, the media quoted an expert set to head an investigation team as saying.
