Diablo Canyon nuclear power plant is scheduled to close their reactors in 2024-25. They are closing because reactor 1 was commissioned in 1968 and reactor 2 in 1970, so they are both very old. They were built in a quake and tsunami zone, with the Central Valley and Southern California downwind, and should close today. They tried to build a nuclear plant at Bodega Head on the San Andreas Fault upwind from the Bay Area!
Nuclear power plants cool themselves by either transferring their heat to air towers, or they use water like Diablo Canyon, which uses 2.5 billion gallons a day taken from the cold Pacific, then releases it back hot. Ocean heating is causing environmental calamities. Nuclear waste must be cooled and is dangerous for centuries. Mining, milling and transportation of uranium pollutes.
Diablo Canyon is run by PG & E, whose equipment is responsible for deadly fires and went bankrupt. Are they cutting corners on safety, yet again? After an accident or quake it will be too late to find out. Solar and wind are much cleaner and safer.
