The yearlong outage at the troubled San Onofre nuclear power plant near San Diego has cost Edison International (NYSE: EIX) more than $400 million in repairs, inspections and replacement power expenses, according to the LA Times. The two-unit, 2,100 MW plant has been offline since January 2012 after Edison found unusual and premature wear on tubes in the steam generator, one of which sprung a small leak of radioactive steam in January 2012.
Edison reportedly also told analysts this week that the manufacturer of the faulty tubes, Mitsubishi Heavy Industries, said replacing âsignificant portionsâ of the system could take more than five years, according to the LA Times. The NRC is currently reviewing a request by Edison to restart the least damaged of the two active reactors and run it at 70 percent power. The plant supplied power to roughly 1.4 million homes in Southern California before the outage began.
