Spouted bed design considerations for coated nuclear fuel particles - (PPT)

摘要

1. High Temperature Gas-cooled Reactor (HTGR): - Graphite moderated, helium cooled reactor (750°C ≤ T_(exit)≤ 900°C); - Fuel kernels 425 μm - 500 μm; 10.8 - 11.2 g/cm~3; - Kernels hermetically sealed in 4 coating layers (TRISO particle); - Layers form the primary containment for fission products.
