A conceptual design for a small HTGR in the 100 MWe size range is described. The reactor drives indirect closed-cycle gas turbine power conversion units using helium as the working fluid and provides both electricity and thermal energy via a 380 F hot-water utility system to serve the projected needs of large US Army installations and industrial facilities in the continental US in the post-1985 time frame. The overall system design combines many of the proven features of the Peachbottom I reactor, the Fort St. Vrain HTGR core, and Oberhausen II turbomachinery. The major unique feature is the use of an indirect power cycle, with helium-to-helium intermediate heat exchangers. Cost estimates are summarized which indicate the ability of the gas turbine cycle to discharge waste heat at a useful temperature gives the HTGRGT system a significant advantage over nuclear and fossil-fired Rankine systems even though it is inferior to LWR systems on an electric-only basis. The fossil-fired-gas-turbine total-energy concept is identified as its major competitor for the present application.
