Australia, despite widespread n00qular contamination (from mining), does not have any standing reactors.
Currently weathering massive heatwave, their world on fire.
As climate change erupts all over the world, reactors have to be shut down because the cooling water would be inadequate. 5-10 degree could require shut down in many places.
Not a fun procedure, and it's not like computer shut down. Relays are often very old, and because they're mechanical, they may or may not reset properly. Same is the case post earthquake, relay position can not be guaranteed.
