TEMPERATURE COEFFICIENT OF REACTIVITY EVALUATION OF A COMPACT FAST REACTOR FOR SPACE APPLICATIONS

摘要

The objective of this project is to develop a process of analyzing compact fast reactors for space applications. The project evaluates a 1 MW thermal power gas cooled reactor with a 15 year lifetime. While the analysis presented is for a UO: fueled system, a comparison has been drawn to other non-oxide fuels. Using MCNP and heat transfer analyses that incorporate temperature dependent densities, thermal expansion, and Doppler Broadening, the kegand temperature coefficient of the reactor have been determined.
