I can believe there are lots of concerns, but have any disasters actually materialized as a result? At least according to the wiki article posted I can't spot one. If we're using war on Ukraine as an example of why not, I'd expect there to be some incidents to prove the point. Right now it doesen't seem like there are any real issues to having relied on nuclear.
It’s spread out over years of updates, but iswresearch.org has documented the operational developments of the war since the beginning and talked about the many ways Ukraine has been constrained militarily by the need to avoid fighting that could damage the reactors. Russia effectively uses the plant as a shield for a base of operations.
