On study of possibility to mitigate severe accident effects at an underground spent nuclear fuel disposal facility
Abstract. The paper presents the analysis of coefficients of tracer concentration reduction in materials of protective barriers, which are supposed to be used at facilities for radioactive waste and spent nuclear fuel isolation. The analysis is based on the results of numerical experiments of non-stationary diffusion transfer of the stable tracer within a three-layer system "source of contamination – engineer barrier – excavation damaged zone of the host rock". A large scope of values of the observed diffusion coefficients in various zones of the system with account of the varying thickness of the two latter zones has been studied.
