| Research Abstract |
Effects of mixed ion irradiation and repeated pulse heat load on hydrogen isotope retention and surface morphology changes were studied for pure W and TFGR-W, which is known to be resistant to neutron irradiation. Evaluation of different dispersoids (TiC and TaC) was performed to obtain valuable results to modify its performance. TFGR-W with dimensions of ITER monoblocks was fabricated by a newly developed material processing technique using superplasticity.
