Heterogeneous gas core reactor and dual fluid closed cycle power conversion system. Final report, April 15, 1977--December 31, 1977

The basic objective of this research program is the conceptual analysis and preliminary assessment of the Heterogeneous Gas Core Reactor (HGCR) concept and Dual-Fluid power conversion system. The research studies include preliminary HGCR neutronics design and optimization, preliminary analysis of fuel utilization characteristics as well as an assessment of the main safety features and non-proliferating characteristics of the HGCR. The dual-fluid power cycle analysis consists of a preliminary assessment of the basic dual-fluid power cycle to determine conditions for optimum cycle efficiency. Included are assessments of corresponding conventional power cycles for comparison with the dual-fluid power cycle.
