Pre- and postirradiation evaluation of fuel in capsule HRB-14. [HTGR]
Capsule HRB-14 was irradiated jointly by Oak Ridge National Laboratory and General Atomic Company (GA). This report covers the pre- and postirradiation characterization and evaluation of the GA fuel. The experiment was primarily to characterize the irradiation performance of TRISO-coated low-enriched (Th,U)O/sub 2/, UC/sub 0/ /sub 7/O/sub 0/ /sub 5/, and UO/sub 2/ particles and TRISO ThO/sub 2/ particles. Twenty cured-in-place fuel rods containing the fuel particles were irradiated at 960/sup 0/ to 1130/sup 0/C. The fluence was 4.5 to 8.3 x 10/sup 25/ n/m/sup 2/ (E > 29 fJ)/sub HTGR/. The fertile burnup was 4.1% to 8.5% fissions per initial metal atom (FIMA); the mixed oxide burnup was 14.5% to 19.3% FIMA; the uranium fissile burnup was 27.9% to 29.5% FIMA.
