Called a molten-salt reactor, the technology was conceived during the Cold War and forgoes solid nuclear fuel for a liquid one, which it can “burn” with far greater efficiency than any power technology in existence. It also generates a small fraction of the radioactive waste compared to today’s commercial reactors, which all rely on solid fuel.

And, in theory, molten-salt reactors can never melt down.
