Unit 3 at San Onofre Nuclear Generating Station appears to be out for maintenance for a month. However, government regulators--who are supposed to keep a strict watch on reactors due to their potential for deadly radioactive leaks--missed or were caught with incorrect information about the reactor. The outage is not from an accident or refueling, according to information gleaned from several sources. The reactor was shut down October 9. Initially, the Nuclear Regulatory Commission provided no record of the shutdown. An NRC spokesperson reported it was in \u201cmaintenance\u201d but refused to provide any details. Southern California Edison, the nuclear plant\u2019s primary owner, stated only that the outage was for routine maintenance \u201cto prepare the unit for operation next year.\u201d A spokesperson declined to comment whether the outage is related to a planned $782 million installation of new steam generators at the facility, as the current ones are failing.
