[en] The objective of this paper is to present the analysis of radiation characteristics for the ductile cast iron CASTOR RBMK-1500 and heavy concrete CONSTOR RBMK-1500 casks loaded with spent nuclear fuel from Ignalina NPP RBMK-1500 reactors. These casks are designed for an interim storage (up to 50 years) of spent nuclear fuel at Ignalina NPP. Computer calculations have been performed using SCALE4.3 computer codes system. The dose rate calculations have been performed on the sidelong, upper and lower surface of the casks and for certain distance at the beginning of spent nuclear fuel storage in the casks and after 50 years of interim dry storage. The results obtained results show that dose rate values on the surface of the cask are much less than the design criteria value 1000 μSv/h when the average burn-up of fuel assembly is 20 GWd/tU. It was revealed that CONSTOR RBMK- 1500 cask has better shielding characteristics than CASTOR RBMK-1500 cask.(author)
