You do know that you can build nuclear power plants almost anywhere?
Four of the french ones are not at water sources. The biggest in the US is located in a desert. Katar has nuclear reactors.
Why would site selection be difficult?
I got an error there. They are built by water sources but 11 of 15 power rely on evaporative cooling via cooling towers. There is the possibility of dry cooling, which doesn’t use external water.
- Geological stability is not relevant with on site storage in spent fuel pools or dry caskets.
- If you keep risk assessment up to date that is not a problem (tsunami walls, emergency pumps/generators automatic shutdown, …)
- Security risks are of a concern not only for nuclear power plants. Think of pumped hydro. The Ukrainian reactors at Zaporizhzhia have very high standards of protection. Thick concrete walls, steel containment. It would be cheaper to start nuclear attacks, than to try to create a nuclear catastrophe by damaginh the reactors. But better save than sorry, hence the warnings by IAEO.
- Ground stability is a factor in every building. Especially high ones with small ground area and strong forces acting on them… like wind turbines.
