That's a very simplistic way to look at the situation.

At a large trade show, I once ran into a retired nuclear engineer and we had a long conversation: he had been called back into service by the state out of desperation. There weren't enough knowledgeable folks who could do safety audits of the plants for TüV. This was 14 years ago and things would be far worse today.

Restarting a complex industry (and it's ageing plants) that's been out of favor for literally decades is difficult and in this case also dangerous.

I'm a (German) physicist by training and worked at a nuclear research facility at the time.
