| Research Abstract |
EMAR measurement system for neutron-irradiated materials was developed. Systematical experiments using thermally-aged Fe-Cu alloys clarified the relation between EMAR characteristics and matrix structural changes during Cu precipitation process. Using the measurement system at hot-lab facilities, EMAR characteristics of neutron-irradiated RPV steels were examined and the feasibility of EMAR method for nondestructive evaluation of irradiation embrittlement was discussed.
