Transatomic Power publishes details of MSR concept

Transatomic Power

Back in 2012, we blogged about Transatomic Power (TAP), a Boston-based start-up aiming to design what they call a Waste Annihilating Molten Salt Reactor (WAMSR). TAP have now released a technical white paper which provides greater detail about their reactor concept.

The paper reveals that their 520MWe MSR concept makes use of a zirconium hydride moderator combined with a lithium fluoride fuel salt. This innovative combination would enable the reactor to run on spent nuclear fuel, or fresh low-enriched uranium, thus providing both a high level of proliferation resistance and an efficient way of consuming existing nuclear waste. TAP also suggest that the use of hydrogen-dense zirconium hydride as moderator, instead of graphite, will reduce the size and cost of the reactor vessel.

Like all MSR concepts, TAP’s reactor offers very high fuel burn-up, up to 96%, and a range of passive safety features. TAP believe that their reactor could be constructed for just $2 billion per plant, with a 3-year build time.

This is just one of many exciting MSR concepts being developed around the world. As others have reported, start ups are now home to some of the boldest innovations in nuclear energy. For more information on other MSR projects worldwide, see our world map.

We’ll be following TAP’s progress with great interest. Check out the technical white paper here.
