DAMAGE PARAMETERS FOR CANDIDATE FUSION MATERIALS IRRADIATION TEST FACILITIES

[摘要] A comparison was made of damage parameters for carbon, iron, and molybdenum irradiated in spectra for D-Li, spallation, and beam-plasma (D-T) neutron sources and a reference DEMO first wall spectrum. The transmutation results emphasize the need to define the neutron spectra at low energies; only the DEMO spectrum was so defined. The spallation spectra were also poorly defined at high neutron energies; they were too soft to produce the desired gas production rates. The treatments of neutron-induced displacement reactions were limited to below 20 MeV and transmutation reactions to below 50 MeV by the limited availability of calculational tools. Recommendations are given for further work to be performed under an international working group.
