摘要: A Mars surface power system configuration with an output of 3 kWe and a mass 775 kg is described. It consists heatpipe-cooled reactor UN fuel coupled to Stirling engine fixed conical radiator driven by loop heat pipes. Key achieving this low the use highly radiation-resistant multiplexer for monitoring controlling reactor, as well radiation resistant generators motors. Also key judicious placement shields prevent scattered from Martian air damaging controls. Several alternate configurations also are briefly looked at, including moderated UZrH using 233U instead 235U. The has essentially same baseline unmoderated yields shielding requirements. significantly smaller about 228 lighter than 235U, but part weight reductio...
