Abstract :
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 (≈20%), small radiator size (≈5 m5/MWe) and high specific power (≈10 kWe/kg)
