>Building nuclear doesn't stop you from building whatever else you want.

It kind of does though, since it demands pretty lavish subsidies to be built at all and those subsidies would give WAY more bang for the buck if used on pumped storage, batteries, solar and wind.

You also have to cap liability in case of nuclear disaster. Private insurers won't touch nuclear power with a barge pole unless taxpayers are forced to pay for disaster cleanup. As a taxpayer Id rather not have that liability.

We're not allowed to flood valleys anymore, so pumped storage is not cheap. Maybe that would change if there was a climate emergency cough
