Fusion neutronics and the nuclear data

For the International Thermonuclear fusion Experimental Reactor (ITER), shielding calculations with the extremely complicated geometry have been carried out by MCNP, where FENDL-2.1 is adopted as a reference nuclear library. In the ITER Test Blanket Module (TBM) program, prototypes of breeding blanket will be tested at ITER. The Integral test of the TBM mock-up has been carried out at FNS. For the International Fusion Materials Irradiation Facility (IFMIF), D-induced activation cross sections of the IFMIF accelerator materials have been measured at the TIARA AVF cyclotron. (author)
