Other than the oft-mentioned risks of nuclear, it is (1) not as cheap as you think and (2) not straightforward to maintain in a warming environment.

1. Nuclear power is far more expensive than renewables, due to the high costs for construction and dismantling. This does not dismiss your argument, because running a nuclear power plant is fairly cheap. The costs therefore speak towards keeping nuclear power plants running as long as they remain safe.

2. Existing nuclear power plants use huge quantities of fresh water for cooling. The required water quantity and temperature make nuclear power plants prone to droughts, which can cause shutdowns, and to flooding events, which can shut down or damage the plant. Both droughts and floods are increasing in frequency due to climate change. This speaks towards closing down power plants that are particularly vulnerable. In any case, grid operators need to be able to mitigate nuclear power plant outages. The cost of nuclear power is even less attractive when overcapacity is needed to accommodate potential outages.
