Irradiation of MiniFuel Targets Bearing TRISO Fuel Compacts (Status Report)

UCO TRISO Minifuel FY23 NSUF-Kairos Power Post-Irradiation Examination Status Report

“…After target disassembly [6] at the Irradiated Fuels Examination Laboratory (IFEL), the recovered subcapsules were queued for puncturing to collect fission gas release (FGR) measurements prior to subcapsule disassembly. The FGR results are discussed in Section 4.1.…”

“…For the higher target temperatures, the experimental temperatures are lower than the predicted ones. The average kernel and SiC layer temperatures over the length of the irradiation were estimated from the dilatometry results and the predicted average temperature of the components [6].…”

“…Five MiniFuel targets were assembled, as described in Le Coq et al [5]. The start of the post-irradiation campaign, the target disassembly, is recorded in a previous status report [6]. This report describes the subsequent post-irradiation examination (PIE) results collected to date on the KP MiniFuel targets.…”
