The U.S. Department of Energy (DOE) gaseous diffusion plants operated by Martin Marietta Energy Systems, Inc., which produce enriched uranium, use a thermosyphon heat rejection system. In this system, thermal energy from the process gas (UF[sub 6]) is transferred to a natural convection boiling loop in which the working fluid is CFC-114. When CFC-114, which is a partially halogenated chlorofluorocarbon, dissociates in the atmosphere, it is believed to accelerate the rate of ozone (O[sub 3]) destruction. Because of large CFC-114 fugitive losses from the operating plants and growing environmental concern over ozone depletion, the DOE has begun a program to identify an alternate cooling system design.
