Nuclear Science User Facilities 82 Future Activities The results obtained by NDE charac- terizations are consistent with those predicted by computational modeling incorporating the known effects of irradiation in SiC/SiC composites. Within the present project, additional experimental data, including thermal conductivity, stress state, and helium permeation will be generated to further validate the multiphysics model and computation.The study will contribute toward fully estab- lishing predictive capability regarding failure probability and behavior of SiC-based fuel cladding and core structures during the normal and off- normal operation of nuclear reactors.
