Modelling of RBMK-1500 SNF storage casks activation during very long term storage

This paper presents modelling results of storage casks neutron activation during 300 year storage period. Modelling results show, that after 50 years of storage, side-wall and bottom of CASTOR®RBMK-1500 cask are activated above clearance criteria. However, for 100-300 year storage period all of the casks components could be free released.
