Calculational modelling of target nuclide build-up in the RBMK reactor at leningrad nuclear power plant

Abstract Software support of radiation technologies being implemented at Leningrad NPP is considered. The procedure of 60 Co build-up data (and their errors) evaluation is demonstrated through calculation of 60 Co build-up rate in an irradiation assembly situated in a core channel at LNPP reactor #4 of RBMK type.
