Three incidents last week at the San Onofre nuclear power plant in California have raised concerns. A small radiation leak early in the week required operators to shut down the reactor; later, maintenance professionals discovered extensive wear on tubes carrying radioactive water. On Friday, news reports said a worker had accidentally fallen into a reactor pool. "To have this many failures is to have a real breakdown in quality assurance, maintenance and safety culture," said Dan Hirsch, president of the Committee to Bridge the Gap, a group that monitors the nuclear industry.
