There are three problems: 1) Generations of nuclear engineers either told big lies or made huge errors of engineering; resulting in staggering disasters in Russia & Japan which will mark our planet for a period far longer than current human history. 2) The main use of nuclear plants was to create refined product for nuclear weapons, now we have vastly more of that stuff than you can imagine lying around. We don't need or want any more. I believe that a single facility in the north west of england has sufficient plutonium for 40,000 nuclear weapons. 3) They are wildly expensive compared to other forms of "clean" power - solar, hydro and wind are just far far cheaper in terms of both invested carbon, $ and collateral environmental damage. Apart from that fission is just fine.
