That’s what I was wondering. Light off a tactical nuke on it to burn it all up..
That action would disperse more radioactive material than it would destroy. That would be bad.
It is possible to place neutron emitters and moderators around the hot zone to increase the flux and the rate of burn. That might reduce the half-life of the most severely contaminated areas. Or it might not.
We will find out one way or another. The natural processes of rainfall and underground water tables containing dissolved minerals will introduce neutron emitters and moderators into some of the contaminated areas. That will cause intermittent flaring of the radiation levels followed by steam venting.
Oh yeah no harm could come from setting off a nuke. doofus
