Chernobyl's unit 4 was destroyed by an explosion.
Fukushima had multiple explosions that destroyed the upper levels of reactor buildings, and ruptured the containment of unit 2.
During the three mile island accident there were several days where engineers were sweating bullets because there was a hydrogen gas bubble at the top of the pressure vessel, and they were afraid it would explode. It was only after about a week of effort that they were able to eliminate the H2 bubble.
Every nuclear reactor has the possibility of immense damage due to explosion - steam explosions, explosive gas, and secondary systems such as diesel and electrical system. It is one of the primary hazards that control systems and emergency cooling and venting are there to deal with. Lying to everyone that it's not possible isn't helpful to the nuclear community.
- Nimitz14 7y agoThey do not blow up in the sense of a nuclear explosion. It's a normal explosion. With normal consequences.
- jhayward 7y agoWhen you blow up a bunch of radioactive material in a large steam explosion you get widespread contamination from fallout and a massive cleanup necessary to recover the scattered material, as well as dealing with the melted core material. That's not "normal".
- anoncake 7y agoThey blow up in the sense of a dirty bomb. That's a lot worse. It would be great if NPPs just blew up in a nuclear explosion! We could safely use them by making the blast radius a forbidden zone.

- anoncake 7y agoThen please explain impolitely where you think I'm wrong. To clarify: “great” is no absolute, an NPP that generates electricity is obviously better than one that explodes. It also depends on the size of the explosion. A Hiroshima-class explosion would be acceptable, the one of a tsar bomb might not be. Also an NPP that fails like that would still kill its operators and perhaps some unlucky farmers. But compared to the actual worst case, that's negligible.
- petre 7y agoThey blow up just like a pressure cooker blows up. If we build an unpressurized reactor with unflammable coolant, nothing ever blows up.
