The troubled San Onofre Nuclear Generating Stationâs Unit 2 is ready to be operated safely at 100 percent capacity, says plant operator Southern California Edison. The operator says the findings from a recent technical evaluation of the facility bolster its plan to begin operating the reactor at a more conservative 70 percent power for five months.
The plant, located near San Diego, has been offline since January 2012, after SCE found unusual wear on new tubes in the steam generating system. One of the tubes, which were manufactured by Mitsubishi Heavy Industries, sprung a small leak of radioactive steam in January 2012, prompting a year of investigations and evaluations at the facility. The outage and repair costs to the plant are estimated to have exceeded $400 million.
