Leaks in San Onofre Unit 3 and Unit 2:

On February 18, 2011, operators restarted the Unit 3 pressurized water reactor (PWR) at the San Onofre nuclear plant in southern California following its sixteenth refueling outage. During the outage, workers replaced both of the reactor’s steam generators, which are large cylindrical containers that are partially filled with water.

At 3:05 pm on January 31, 2012 – less than a year later – radiation alarms alerted the control room operators that water was leaking through one or more of the tubes in one of the steam generators on Unit 3. They estimated the leak rate to be 82 gallons per day.

After touring San Onofre's troubled nuclear power plant Friday, Nuclear Regulatory Chairman Gregory Jazcko attempted to reassure the public with a news conference that detailed inspections done in the wake of a radioactive steam leak that shut the station down in January.

The nation's top nuclear regulator toured the troubled San Onofre Nuclear Generating Station Friday along with Sen. Dianne Feinstein and Rep. Darrell Issa.

Neither unit will be allowed to restart until the exact cause or causes of the wear and leak are determined, Jaczko said.
