Utah would be wise to look into building plants of this type, especially as a solution for disposing of spent fuel from conventional nuclear plants.

Commercially, a $2 billion dollar 520MWe power plant can meet the needs of utilities facing only gradually increasing demand as well as those whose service area doesn’t require the 1000MW plus size of a conventional reactor, or those wanting to replace fossil-fueled load-following or baseload coal plants. Build time is estimated to be 36 months. The plant does not require any source of cooling water – the molten salt fuel liquid acts as its own coolant as it flows thru the primary loop, transmitting heat (but not radiation) to an intermediate loop. The lack of any requirement for cooling water dramatically increases the number of potential build sites. In fact, its inherent safety characteristics would allow for these reactors to be sited near large population centers, avoiding lengthy transmissions, reducing costs due to power losses and transmission line construction.
