In the analysis of nuclear and radiation safety of existing and designed BN reactors considerable attention is paid to the problems associated with their fuel.

This paper describes the approaches to determine radiation characteristics of non-fuel compositions and structural elements of fuel assemblies (FA) and non-fuel assemblies of the core. The latter include the control and protection system (CPS) assemblies (reactivity compensators, regulators, emergency protection, assembly sleeves) and in-vessel storage shielding assemblies (steel and boron carbide assemblies).

Since the volume of information for analysis is quite extensive, from the neutron-physical calculation of the reactor and the simulation of the corresponding compositions irradiation to further monitoring of the processes in the cooling pond (CP) and solid radioactive waste storage facility (SRWSF), a convenient calculation tool with the modern nuclear data is required for a systemic and complex approach. The results of research in this direction are presented in this paper.
