The prediction of radiation doses obtained during dismantling of steam generator represents one of the most crucial issues within the process of decommissioning of nuclear installations. Given the fact that in Slovakia the nuclear power plant VI in Jaslovské Bohunice is currently being decommissioned, represents the analysis of the segmentation of steam generator an actual issue. In this paper, the proposed dismantling methodology together with the results of calculations is given. Also the complex analysis of the influence of different distance of workers carrying out the dismantling as well as the influence of the time on the total collective effective dose is carried out. The results of this analysis show that the obtained doses are below the legislative limits and thus the main consequences can be applied in the process of VI nuclear power plant decommissioning.

Przewidywanie dawek promieniowania na które narażona jest obsługa w trakcie demontażu generatora pary reprezentuje jedną z najbardziej kluczowych problemów w ramach procesu likwidacji obiektów jądrowych. Mając na względzie fakt, że na Słowacji elektrownia jądrowa VI w Jaslovské Bohunice jest obecnie wycofywana z ruchu, analiza segmentacji generatora pary stanowi aktualny problem. W pracy zaproponowano metodologię demontażu i podano rezultaty obliczeń. Także złożona analiza wpływu różnych odległości pracowników przeprowadzających demontaż jak również wpływ czasu na całkowitą efektywną zespołową dawkę promieniowania jest przeprowadzony. Wyniki tej analizy pokazują że przyjęte dawki są poniżej limitów wyznaczonych normami i zatem główne konsekwencje mogą być stosowane w procesie demontażu jądrowej elektrowni VI.
