No, I never said that. I very patiently explained the physics of why there was no thermonuclear reaction occurring, which is what you suggested as a heat source.
I have no fear that any more radionuclides are going to be expelled than there ever were ~ that part of the science is certainly settled, eh! It ain't gonna' blow up, but the fellows running the show (presumably all highly trained physicists and atomic power plant engineers and designers) said the heat increase wasn't explainable.
