Theoretically, there's no better, more practical source of reliable, carbon-free energy than the current generation of nuclear reactors. In practice, the theory holds water, but there are still a few ...

Breakthrough hailed for allowing 100 times more energy to be extracted from the same type of fuel used in water-cooled reactors China has tested a new residual heat removal system that could make its ...

The first breeder reactor, i.e., one that produces more nuclear fuel material as a byproduct than is used to generate energy, went online almost 75 years ago. So, it's hardly some form of sci-fi ...
