NUCLEAR EXPLOSION????
TOTAL B.S. In order to have a ‘Nuclear Explosion’ you have to have a critical mass of 95% or greater enriched uranium. Fuel grade uranium rods are less than 3% enriched.
A nuclear explosion can ONLY occur as a deliberate act under controlled conditions. It is simply not a possible result of a meltdown.
The only thing explosive here is the rhetoric.
How about a low energy nuclear reaction ~ here we have fissile materials in a high pressure pure hydrogen environment ~ there’s certainly the makings of a bit of fusion.
