Abstract

The blanket structure of the SlimCS has been studied under coolant condition of Pressurized Water Reactor (PWR) to improve the compatibility with F82H. The neutronic and thermal calculation are performed for the simplified blanket structure, which Li 4SiO 4 pebbles or Li 2O pebbles for tritium breeding and Be 12Ti pebbles for neutron multiplication are mixed and these pebbles are filled in the blanket. As a result, the TBR of blanket by PWR water condition is higher than those of sub-critical water condition because the tritium breeding area in the blanket is extended by decreasing thickness of coolant tube in comparison with sub-critical water condition. The blanket with PWR water condition can attain target of the net TBR (≥1.05) and satisfy condition of conducting shell for MHD stability.
