Abstract Objective To study the radiation effects of spent fuel transportation from Guangdong to northwest region under different modes.Methods Using the CRAMTRA 1.0 code, radiation doses of spent fuel transportation under different modes on the typical public and workers were calculated.Results The public collective effective dose per ton of spent fuel delivered to the public had the greatest impact on long-distance road transport (1.65×10-3 Sv/t), while the Road-Ocean-Rail transport mode had the least radiation impact (2.63×10-4 man·Sv/t), and the radiation impact of Road-Rail transport mode was the middle (4.51×10-4 man·Sv/t). The long-distance road transport mode had a significantly higher occupational exposure to workers (6.00×10-1 man·Sv/t) than that of Road-Rail transport mode (7.93×10-2 man·Sv/t) or Road-Ocean-Rail transport mode (1.05×10-1 man·Sv/t).Conclusion The radiation effects of Road-Ocean-Rail transport mode is relatively small.
