Activation analysis and evaluation of the radionuclide inventories, decay heat for European DEMO divertor components

This work presents neutron flux calculation results and specific decay heat and activity for the European DEMO reactor divertor structure. Two DEMO 2017 models were used in calculations; one with a homogenised WCLL breeder blanket and the other with a homogenised HCPB breeder blanket. The neutron fl...

Description
Summary:This work presents neutron flux calculation results and specific decay heat and activity for the European DEMO reactor divertor structure. Two DEMO 2017 models were used in calculations; one with a homogenised WCLL breeder blanket and the other with a homogenised HCPB breeder blanket. The neutron flux calculations were performed using MCNP6 code with JEFF 3.2 nuclear data. Activation and decay heat calculations were performed using the FISPACT-II code with TENDL – 2017 nuclear data library. •The first phase of the EU DEMO irradiation scenario was considered for analysis.•Neutron-induced activities, decay heats on the divertor components were calculated.•Two DEMO 2017 models with different breeding blanket integration were used: HCPB and WCLL.
