New nuclear reactors are fully or nearly fully automated I think. If humans disapeared overnight, they can fully shut down by themselves. Also newer reactors are made so that you need to actively monitor the reaction to even keep it going unlike old reactors (that are not in use anymore I think) that had you monitoring it to prevent it blowing up.

Playing devils advocate here:

Automated systems are not maintenance or error free and the costs of mistakes are vast. It may have been designed to detect problems and shut itself down; but has it been maintained well enough to successfully do so? Maybe, maybe not.

Given how well maintained most public infrastructure is, I'm not very confident.

A shut down nuclear power plant is a problem though. Especially when you consider that many people here advocate for a massive increase in the number of nuclear power plants. A river going dry, a shore line that moves, future wars or pandemics that we can't even foresee now. All these are huge risks for nuclear energy. For really no reason since there are renewable energy sources that do not share these risks.

The overhype of nuclear power seems completely surreal to me.
