Just look at the explosion of the north stream pipelines. Whether this were government actors, terrorists, or a rogue military interest group independent of government decisions is unknown. But the very same can happen with nuclear plants. Yes they are protected against terrorist attacks (to some extend), but once you factor in military grade capability, the security assumptions crumble. No need for a full-blown nuclear war to happen at all, NPPs are a risk to national safety.

That argument is exclusively used for nuclear. Hydroelectric is far more vulnerable to bombing, but we don't pearl clutch about that risk. And yes, a capable military can -- if they so choose -- turn a nuclear plant into a dirty bomb with sufficient explosives. But why go through that trouble when you can just drop a dirty bomb directly on top of a city center? That's a far more effective way of spreading nuclear radiation. However, capable militaries don't use dirty bombs because they make no strategic sense.

You asume intent. A NPP is a threat if it is in an active warzone, even if no party intents to damage it. It is just in the chaotic nature of war.
