Denatured Molten Salt Reactors (DMSR): An Idea Whose Time Has Finally Come?

摘要

Molten Salt Reactors are one of six next generation designs chosen by the Gen IV program. Traditionally these reactors are thought of as thermal breeder reactors running on the thorium to ~(233)U cycle and the historical competitor to fast breeder reactors. However, simplified versions running as converter reactors without any fuel processing and consuming low enriched uranium are perhaps a more attractive option. Uranium consumption levels are less than 1/6* that of LWR or a l/4th of CANDU while at the same time offering clear advantages in safety, capital cost and long lived waste production along with increased proliferation resistance. A review of previous work and potential improvements proposed by the author will be presented.
