High–Temperature (600–1200K) Heat Rejection System Trades 2005-01-3122
High–temperature heat rejection systems, as part of nuclear power conversion devices, have been under detailed consideration over the last few years. The National Aeronautics and Space Administration’s Project Prometheus has been the primary supporter of several trade-off studies with the ultimate goal of selecting the most applicable and promising power conversion approach.
One of the considered options for power conversion is anticipated to operate at high (600 to 1200K) temperatures. Operation at such high temperatures dictates special requirements for the cooling system concept and its performance.
This paper presents the basis for proposing that among the studied options, the heat pipe-based system be considered for further development. The paper provides direct comparison of the candidates considered with detailed explanation of the decisions made.
