This report presents the results of the Reactor and MHD Systems Study. A preliminary review of advanced nuclear reactor technologies was performed the gas-cooled solid core reactor and the liquid metal cooled reactor appear to have the greatest potential for application during the 1980-1990 time period specified for this study. Preliminary weight and size estimates on the basis of projected technologies for application with a reference liquid metal magnetohydrodynamic MHD energy conversion system indicated a directly coupled gas cooled reactor including shield and containment vessel would weigh 833,000 pounds 416 tons and have a maximum diameter of 17 ft., whereas an indirectly coupled intermediate heat exchanger liquid metal reactor would weigh 1,030,000 pounds 515 tons and have a maximum diameter of 21 ft. These estimates are based on a reactor producing 1000 MWt power having a lifetime of 18,000 hours. The gas cooled reactor was selected as representative of advanced reactor concepts. Direct coupling of the gas-cooled reactor to a two-phase liquid metal MHD device appears feasible an overall cycle efficiency of 37 was calculated for a helium cooled reactor coupled to an MHD duct using lithium as the working fluid - a reactor subsystem weight of 1.3 million pounds 635 tons was calculated for a 1000 MWt, 18,000 hr. reactor. Alternate MHD working fluids were considered during the study. Recommendations for future studies are identified including more extensive evaluations of both gas-cooled and liquid metal cooled reactor concepts. Author
