Reactor with Circulating Fuel Based on Molten Metal Fluorides for Np, Am, Cm Incineration

Variants of Np, Am, Cm incineration using a portion of the plutonium from VVER-1000, -1200 spent fuel in a high-power molten-salt nuclear reactor (MSR) with a cavity-type core and fuel salts with the compositions Li,Be,An/F and Li,Na,K,An/F are discussed. The high nickel alloy KhN80MTYu was chosen as the structural material for the fuel loop. To obtain the highest possible transmutation efficiency, the MSR was integrated with a module for recycling actinides and purifying the fuel salt from fission products. A preliminary validation of MSR operating conditions is included.
