The US Nuclear Regulatory Commission hit Southern California Edison’s San Onofre Nuclear Generating Station (SONGS) with a violation for what it called a lapse in plant security, the agency announced late Thursday.
The NRC noted the violation during a four-day inspection in May. SONGS has been completely offline since January, when a radioactive leak led to the discovery of severely degraded heat exchanger tubes in both of the plant’s (nominally) operating reactors. (In July, the NRC released its report on the tube failures, saying that although plant operators had made major design changes that affected the stability of the tubes, they had not violated any laws.)
Regulators said Edison “failed to develop procedures to monitor electronic devices related to security,” but the NRC has withheld most of the details of the violation.
San Onofre has a long list of safety and security problems dating back long before the latest tube debacle. In January, around the same time as the radioactive leaks, a SONGS worker accidentally fell into one of the facility’s spent fuel storage pools while trying to retrieve a dropped flashlight. And just two weeks ago, an investigation uncovered a staggering number of fire safety violations that continue to go uncorrected, despite previous NRC warnings.
Thursday’s notice of violation comes just days after a high-ranking official on California’s Public Utilities Commission said that SCE and San Diego Gas & Electric should not be allowed to collect revenue on a plant that is not generating any electricity:
Joseph P. Como, head of the PUC’s Division of Ratepayer Advocates, sent a letter to the commissioners this week stating they should “remove [San Onofre] from Southern California Edison’s … and San Diego Gas & Electric’s… rate base now instead of waiting several more months and allowing hundreds of millions of dollars in needless costs to be borne by customers.”
And, as noted in the Orange County Register, that cost is substantial:
Edison, the plant’s operator, is charging ratepayers about $54 million per month for a nonproducing plant, the letter said. Edison holds 78 percent of the plant’s ownership, SDG&E owns 20 percent, and Riverside 1.8 percent, the CPUC said.
While the PUC has a provision to investigate rate cuts when plants are down for over nine months (which would be November and December for the two SONGS reactors), Como noted that San Onofre is almost certain not to restart before then, if it is ever to restart at all. The full commission has twice postponed votes on an earlier investigation.
In moving for earlier action, Como referenced a 1982 decision that upheld rules requiring that power plants actually function to be included in the rate base. The California Supreme Court agreed, saying a facility must be “used and useful.”
“It seems very obviously that a fundamental prerequisite for a power generator to be considered “used and useful” is that it actually be generating power,” Como writes. “SONGS does not meet this test.”
Southern California Edison released a letter stating that it looks forward to working with the commission through the normal, long, dragged-out process.
As for the security violation, all the utility would say was that the problem had been addressed.
Word of the latest SONGS violation comes the same week as an NRC announcement of an investigation into violations at North Carolina’s Harris Nuclear Plant [PDF], and a demand from Representative Dennis Kucinich (D-OH) that the regulator’s Inspector General investigate the way the NRC handled the restart of Davis-Besse after cracks were discovered in its containment building.
Edison may think it has addressed its problems, and the NRC might think its process addresses the problems of the country’s nuclear fleet as a whole, but the regular drumbeat of security and safety violations coupled with the perpetual fleecing of the public till calls for a paraphrase of a famous line from the movie The Princess Bride: Address. You keep using that word. I do not think it means what you think it means.
