چکیده

The Neutron induced activity and decay heat are very important for the nuclear design of fusion reactor. In this paper, activation analysis of DEMO reactor with helium-cooled solid blanket (HCSB-DEMO) was performed. Ceramics Li4SiO4 and Beryllium options were considered as tritium breeding material and neutron multiplier, respectively. Chinese low-activation ferritic steel (CLF-1) developed in South Western Institute of Physics (SWIP) was applied as structural materials of blanket. Activation analysis was performed using FDKR code with activation cross section data file FENDL/A-2.0. Neutron fluxes as the input of FDKR were calculated with MCNP Monte Carlo code and FENDL/MC-2.1 neutron cross section data. The activity inventories and decay heat in HCSB-DEMO were examined. The contributions of radionuclides of structural materials, Li4SiO4 and Beryllium in blanket were discussed, respectively.
