Prior IECEC papers by authors from The Garrett Corporation have assessed radioisotope cost/availability guidelines on space power system design (1) and have described the initial development of the Brayton Isotope Power System (BIPS) that reflected these guidelines (2,3). However, significant results from the latter portions of the BIPS program have not been addressed in IECEC proceedings. Also, technology advances in the interim since the early tradeoffs were completed to make a review of these results appropriate. Therefore, the objectives of this paper are: 1) to re-examine design/cost tradeoffs with respect to current economic parameters and technology status and 2) to document significant BIPS design/development accomplishments in the open literature. The results indicate that the use of the highest attainable power conversion system efficiency will yield the most cost-effective systems (lowest cost of electricity, COE).
