As reported by KPBS, a watchdog has called for a federal invetigation into Southern CA Edison's having hidden from the U.S. Nuclear Regulatory Commission (NRC), at a 2006 meeting, its knowledge of flaws in the San Onofre Unit 2 & 3 replacement steam generators. A radioactive steam leak from a failed steam generator tube in January 2012 ultimately led to the permanent shutdown of the two reactors in June 2013. Incredibly, Southern California Edison is seeking to charge ratepayers billions of dollars extra for its "lost profits" and other costs related the permanent shutdown, even though it already charged them for the replacement steam generators, that it knew were defective nine years ago!
