摘要：

The present paper discusses the fission-gas release as measured from three fuels considered for the transmutation process. The releases were measured in spinel-based fuels from the EFTTRA-T3 irradiation [1,2]. Gas puncturing and EPMA data are discussed for three different inert-matrix concepts. The differences in the fission-gas release for the three spinel-based fuel concepts are most likely connected with the concentrations of fission-gas atoms in the fissile phase and in the spinel phase. The present data suggest that homogeneously distributing the fission-gas atoms over the various phases, as would arise from micro-dispersed fuel, gives a lower release than implanting the fission-gas only in the fissile phase.
