AbstractAbstract
[en] Tritium is required for the engineering tests and the initial DEMO fusion reactor. In order to establish a tritium supply method, tritium production using the high temperature gas-cooled reactor (HTGR) was proposed. The B burnable poison (BP) is replaced with Li for tritium production. Li is loaded as a solid unit called Li rod. There is a possibility that difference in an effective multiplication factor (keff) arises by using Li instead of B. The keff difference in the HTTR is evaluated and discussed. The same evaluation is also conducted for the GTHTR300. It is revealed how the difference appears and how the HTGR types influence on the results. (author)
