FASTER, PLEASE: Experiments Start on a Meltdown-Proof Nuclear Reactor: Transatomic Power has begun tests on a very cheap and compact molten-salt reactor. “Transatomic Power, a startup that’s developing a novel type of nuclear reactor, has begun a series of experiments that will either verify its design or send it back to the drawing board. The experiments were made possible by $2.5 million in new investments from Founders Fund, the venture capital firm cofounded by Peter Thiel, and two family funds. The reactor would be smaller and safer than a conventional nuclear unit, potentially making it far cheaper. It would use molten salt as its coolant, making it meltdown-proof and thus requiring fewer costly safety systems. Transatomic’s design could also consume nuclear waste, and it could use nuclear material that couldn’t easily be used to make a weapon.”
