It's starting to sound like the San Onofre plant won't be coming back online any time soon, if at all. Edison just announced it's laying of 1/3 of the workforce at the plant, and both units have been offline for most of the year as Edison & the NRC investigate premature wearing in some piping. The San Onofre plant provided something like 7-8% of power in California. There is clearly a need for replacing this capacity.

On the 'supply side' San Onofre is in a very interesting spot. It is surrounded by San Onofre State Park and the Camp Pendleton marine base. The nearest town is San Clemente (near my own home), and the residents are not at all anti-nuclear. The congressman from the district is Darrel Issa, the chair of the House Oversight and Government Reform committee, who is also pro-nuclear. The San Onofre site seems like an ideal location for new reactor construction with existing (non-operational) reactors, close military presence, and local support.

Yeah, it would take a lot of money to put it back online. Of course, it would be cheaper than building a whole new reactor, but replacing the steam generators would be mucho expensive.

The operators are probably going to sue Mitsubishi, but it will be a long time (if ever) before they get any money from that, so the reactor will likely be shut down for quite some time.

Good luck getting anything nuclear built in CA. For example, a new plant can not be licensed unless a permanent solution to nuclear waste is found. Best I could imagine actually happening is the current steam generators at reduced rating. Better to run at 80% than not at all.

The famous California regulatory environment is actually what makes the specifics of San Onofre interesting. The largest marine base on the West Coast is the reactor's closest neighbor. In a State that has about the worst balance of electricity supply and demand in the country. That situation isn't going to get better as CA seeks to rely ever more on renewables. Camp Pendleton has a serious need for independence from this dysfunctional grid. The base (if not the San Onofre site altogether) would be a great place to deploy DMSRs/LFTRs.

Not sure why Edison hasn't already sued Mitsubishi. The NRC handed them what sounded like a smoking gun ... the modeling error (4X lower flow rates than actual?). Operating at reduced power is probably the best option, but when are they going to get permission for that?

Can anyone else manufacture steam generators for San Onofre? Maybe sue Mitsubishi now and place a new order for generators.

I think the California refusal to accept existing "permanent solutions to waste disposal" is nuts. For years the Fins and French have had a scheme to dissolve the waste into pyrex, cast it into 5cm-walled stainless-steel cylinders and then put it in dry boreholes, entombed in water-proof clay. It's all been tested out the gazoo, too.

This basically turns the waste into radioactive rock and buries it deep. The human race has always lived with buried radioactive rocks...
