In theory. But in fact, attempting to build nuclear power plants results in big increases in electric rates, and the supposed benefits of nuclear power end up being delayed by many years and in many cases decades.

The effect of trying and failing to build nuclear power plants on time and on budget uses up many billions in capital that could've been applied to reliable delivery of renewables.

Even the supposedly efficient French nuclear power program vastly underestimated decommissioning costs.

In other words project risk for nuclear is hideously expensive, even when you think you've dodged project risk problems, there's another whole very expensive project in decommissioning that has its own set of project risks.
