Questions & Answers
Arnie Gundersen, Fairewinds Energy Education: Unit 3 started as a hydrogen explosion – I am in the minority, but I think it’s more than a hydrogen explosion.
I actually think it was something called a prompt moderated criticality that was caused by a hydrogen explosion, which then drove the fuel and scattered particles of fuel for as far as two miles from the fuel pool. […]
The important thing though is that it was a detonation. How it was created is less important than the fact that it was a detonation shockwave and no containment can withstand that.
