ABSTRACT	An integration study was performed by Rocketdyne under contract to NASA Glenn coupling an SP-100 reactor to either a Brayton or Stirling power conversion system. The application was for a surface power system to supply power requirements to a lunar base. A power level of 550 kWe was selected based on the NASA 90-day study of the Moon and Mars. Reliability studies were initially performed to determine optimum power conversion redundancy. This analysis resulted in selecting three operating engines and one stand-by unit for both the Brayton and Stirling options. Integration design studies indicated that either the Brayton or Stirling power conversion systems could be integrated with the SP-100 reactor. Stirling had a 5 percent mass advantage for 1000 Vdc output and the Brayton a 2% mass advantage for 1000 Vrms, 1 kHZ output. The Brayton radiator area was 3.2 times larger than the Stirling. The same SP-100 reactor was used for both the Brayton and Stirling Systems. Because of the higher efficiency of the Stirling cycle (29.7 percent versus 23.8 percent), a longer reactor lifetime results (9.6 yr for the Stirling and 7.6 yr for the Brayton). A description of installation and maintenance operations is also included.
