AGR-1 Safety Test Predictions using the PARFUME code

Abstract

The PARFUME modeling code was used to predict failure probability of TRISO-coated fuel particles and diffusion of fission products through these particles during safety tests following the first irradiation test (AGR-1) of the Advanced Gas Reactor program.These calculations support AGR-1 Safety Testing, which is part of the post-irradiation examination effort on AGR-1. Modeling of the AGR-1 Safety Test Predictions includes 620 days of irradiation followed by 300 hours of safety testing for selected AGR-1 compacts. Results include fuel failure probability, palladium penetration, and fractional release of fission products.
