KIEV, Ukraine (AP) - Ukraine's Chernobyl nuclear power plant was set to reach its full operating output Monday, three days after authorities restarted it in the face of international criticism. Chernobyl plant operators launched the second turbo-alternator of the plant's only working reactor Monday. The reactor was expected to hit 100% of its electrical capacity by Monday afternoon, officials said. The No. 3 reactor was shut down for planned repairs on July 1 and was restarted Friday at 5% of capacity. Chernobyl officials insist the reactor is safe.
