Nuclear is a special flower, in the sense that the worst-case malfunction scenario in many reactors is a chain reaction which leads to widespread dispersion of hazardously radioactive material, be it with or without a massive explosion. In other words, the "L_infinity norm" damage potential of nuclear is higher than coal, solar, wind, and perhaps even hydro (although dam breaches are quite lethal).
It's also true that if you take the "L_1 norm", i.e. the expected damage, it may well be a regular flower and not special (perhaps even less-special than coal for example). But then it's a game of trust with the kinds of companies and state institutions which in many countries have proven as untrustworthy in preventing industrial / infrastructural accidents.
