I think that modern designs are at least an order of magnitude safer than reactors from early generations. Chernobyl's RBMK and Fukusima's BWR/1 were both designed in 60s.

Plus, such a concentrated power source is going to invite a terrorist attack by something like drones, which can't be effectively defended against. An attack that looks like this:
