Overview

Numerical study reveals fuel utilization and safety benefits in HTGR configurations, indicating V2 as optimal design.

Key Points

  • Fuel utilization surpassed 91% with 12% enrichment in the V2 core geometry, demonstrating superior performance.
  • Analysis of three geometries (V1, V2, V3) and fuel enrichments showed clear dependencies on configuration and enrichment levels.
  • Monte Carlo simulations assessed fuel cycle performance and time-space characteristics for the HTGR reactor.
  • These findings support V2 as the preferred reference configuration for future HTGR reactor designs.
