Do you really, really, want chunks of plutonium

We do have nuclear power stations which can and do explode....

Well if you count a hydrogen explosion that happened because the staff

might be slightly radioactive...

I'm guessing the explosion was a damn big venting. DOH! Health and softy shooting itself in the foot yet again!
