So radiation is a green liquid which seeps out and melts structures?

No, green ooze is obviously not accurate... However, as a concept it is much closer to reality, as a meltdown involves the core of a reactor melting into an amalgamation called corium that can melt through structures and emits ...

TL;DR
I think the destruction of nuclear reactors should be made more realistic by replacing the explosion animation,
since nuclear reactors cannot undergo a nuclear explosion in the way a nuclear warhead can.


What ?
I'm suggesting that a meltdown animation replace the flash and explosion ...
