MIT alumni Dr. Leslie Dewan and Mark Massie founded Transatomic Power in 2011,[1] and its board directors included E Ink Corporation co-founder Russ Wilcox.

[5][6] The company discovered that in 2016 it had made errors in its early analysis and realized that the design couldn't consume nuclear waste.

[8] Transatomic initial concept was that of a Waste Annihilating Molten Salt Reactor (WAMSR) designed to digest spent nuclear fuel.

[10] This design was later updated and corrected, and the claim that the reactor is able to use nuclear waste as fuel was dropped.

[11] The latest design is based on a low pressure, high temperature molten salt reactor.
