ABS>Possible designs were considered for a mobile gascooled nuclear power plant to produce 500 kw(e) for military applicationg. Included in the study were consideration, optimization, and selection of coolants (air, nitrogen, helium, argon, or others); thermodynamic cycles (direct open-cycle, direct closed- cycle, and dual cycles, beth regenerative and non-regenerative); reactor moderators (beryllium oxide, metal hydrides, water, or no moderator); shielding (during operation and transport following operation); high temperature materials (for reactor core, reflector, controls, shielding, structure, heat exchangers, and turbomachinery), and investigation of many other variables. Conceptual designs were completed for several systems. The High Density Moderated Reactor System, designated HDMR, evolved as the optimum gas-cooled nuclear power plant for military applications, and is described in detail. This concept utilizes a closed regenerative Brayton cycle with air as the working fluid. HastelloyX pins are used in the 16-inch diameter core; some contain UO/sub 2/ fuel and some contain yttrium hydride moderator. The hydrogen moderation provides maximum safety within acceptable shield weights. Other systems studied are also described. The HDMR offers significant advantages over existing military power plants, both nuclear and fossil fueled, in terms of logistic support requirements, mobility, reliability and simplicity. (auth)
