Material testing capability of the fusion engineering facility, FEF

A neutronics analysis is performed for FEF to examine the materials testing capability and radiation damage rates in the components. It is found that an average atomic displacement rate of ~ 60 dpa could be obtained in the first 24 l of the test module volume within 10 y. Neutron streaming through ducts for the neutral beam injector and radiofrequency heating as well as through the end plug region seriously affects the system performance of FEF.
