The technique of calculation of hydrogen ingress into the secondary circuit of the BN-600 power unit after replacement of the PGN200M steam generator stages is presented. The hydrogen diffusion from the water-steam circuit from the new evaporator stages of which the heat exchange surfaces have not been subjected to the passivation yet is shown to be the main source of ingress.
