Studies are being conducted on an innovative space power system that combines a uranium tetrafluoride (UF4) ultrahigh-temperature vapor core reactor (UTVR) and a disk magnetohydrodynamic (MHD) generator to obtain closed-cycle burst-mode operation (hundreds of MWe power level for a few thousand seconds). Use of UF4 as the vapor fuel and metal fluorides as the working fluid in the UTVR/MHD generator allows for operation on a direct, closed-Rankine-type cycle and leads to space power systems with high efficiency ( approximately=20%), small radiator size ( approximately=5 m5/MWe) and high specific power ( approximately=10 kWe/kg).
