| 英文摘要 | Abstract china spallation neutron source (csns) is intended to begin operation in 2018. csns is an accelerator-base multidisciplinary user facility. the pulsed neutrons are produced by a 1.6gev short-pulsed proton beam impinging on a w-ta spallation target, at a beam power of100 kw and a repetition rate of 25 hz. 20 neutron beam lines are extracted for the neutron scattering and neutron irradiation research. during the commissioning and maintenance scenarios, the gamma rays induced from the w-ta target can cause the dose threat to the personal and the environment. in this paper, the gamma dose rate distributions for the w-ta spallation are calculated, based on the engineering model of the target-moderator-reflector system. the shipping cask is analyzed to satisfy the dose rate limit that less than 2 msv/h at the surface of the shipping cask. all calculations are performed by the monte carlo code mcnpx2.5 and the activation code cinder’90. |
