Core design considerations for a large gas turbine HTGR
Advanced high-temperature gas-cooled reactor (HTGR) design concepts for energy production using gas turbine applications depend on cores capable of generating helium coolant outlet temperatures up to 900/sup 0/C. The paper describes a preliminary analysis of a large HTGR (4000 MW(t)) core using a prismatic fuel with coolant gas core outlet temperatures of 850/sup 0/C. This study provides core design considerations in the areas of radial fuel zoning, power distribution, fuel performance, fuel temperatures, and fission product release for a large HTGR core operating under high-temperature conditions. Though the work was performed on a 4000-MW(t) core, all design considerations developed are equally applicable to a 3000-MW(t) core. Potentials for upgrading the core performance and suggested improvements for implementation in future design work are cited.
