Nuclear power is supported by many climate scientists. I think technically it's a fantastic solution. However, I don't think it's a great socio-economic solution and the costs if we fail to deal with climate change may be too high.
Let me explain. Earlier this year a nuclear power plant in Finland had to reduce capacity because the sea waters got too warm.

This is one example where climate change may make it difficult to operate nuclear power plants. Another is that the seas are rising and storms are getting slower which results in more flooding.

These together make operating nuclear power plants difficult.
The last threat is that if we reach the tipping point, we will likely be facing a world where nation states start failing, including our own. Nuclear power plants take decades to decommission and the question is, who will maintain and decommission these things when humanity is faced with much more pressing concerns like maintaining organized human life.
The tipping point is a real concern among scientists. The IPCC recommends policy makers take the real possibility of a tipping point into account and I think questions like "How do we deal with nuclear power plants as nation-states fail" should be taken seriously.

Prominent members in our field like Alan Kay also wrote about tipping points in a report for the NSF Transitions and Tipping Points in Complex Environmental Systems

I'm not a pessimist but a realist. I think it's utopian to not address the concerns of climate scientists and really smart people in our field when making policy decisions, and this includes nuclear.
- renjimen 8y agoThanks for the thought provoking points! It must be strange to plan for the end of civilisation as we know it when constructing one of the crowning achievements of mankind. Very sobering.
- hansthehorse 8y agoReducing power due to high sea water temperature is something any power plan, regardless of fuel type, would have to do. The sea water isn't used to cool the reactor, it us used to condense the steam after leaving the turbine. If the cooling water is very warm adequate vacuum in the condenser is not possible to maintain. To alleviate this problem power is reduced to reduce the condensing load and maintain condenser vacuum. The linked article has factual misinformation in it which isn't unusual for technical pieces in newspapers.
