I think that safety claims re: nuclear are a bit oversold by some, but when the alternative is increased deaths from particular emissions from burning fossil fuels I still find myself leaning nuclear.
e.g. Germany having decided to accelerate its nuclear powerplant shutdowns gets estimated (https://www.nber.org/papers/w26598) at leading to around 1100 additional deaths per year.
You also need to note that the same government at the same time decided to decelerate the growth of renewable energies that were supposed to replace both nuclear and fossil plants. It’s not a choice between nuclear and fossil.
