Perhaps there’s a Freeper who knows what went wrong at San Onofre this past year. Not that there was danger to the public, but what was supposed to be a long term improvement failed. They replaced steam generators at great cost.
This is the primary cause of potential shortages this year. 2000 MW of local power production off line.
The steam tubes were failing/near failure. I would hazard either the metal used was faulty or the operation was beyond normal parameters. 22 months is way too short of a time for normal usage for a normal tube.
The generators were made in NKorea.
