Liquid Salt Thorium Reactors
The Thorium liquid salt reactors are capable of potentially producing slightly more power, or can serve as a potential replacement for reactor designs with less chance of a melt down, and being cheaper.
Due to the one size fits all metholodgy, in aircraft carrier typically two reactors are used, as to mass produce them for use in submarines, battleships and other vehicles. Each reactor is capable of generating roughly 300 MW, similar to the A1B reactor found in Nimitz-class carriers.
The reactor uses a circulating liquid mixture of sodium, zirconium, and uranium fluorides, that can store roughly 200 times the heat in terms of volume than water, having significantly less pressure and reduced likelihood for a failure. Although the liquid salt reactor designs can produce a slightly larger amount of energy (1.15 times more than uranium) the amounts used and size of the reactor are roughly the same. The design uses Plutonium-239 as a catalyst to initiate fission in the fertile fuel.
