HANARO, a 30 MW open-pool type multipurpose
research reactor, has been operated as a platform for nuclear researches in
Korea, and irradiation facilities have been mainly utilized for various nuclear
material irradiation tests requested by users. Although most irradiation tests
have been related to national R&D relevant to nuclear power, demand for
neutron irradiation of electro-magnetic materials is increasing rapidly at
HANARO. Another research reactor, which is named the KIJANG research reactor
(KJRR), is under construction in Korea. KJRR is dedicated to increasing the
national radio-isotopes supply capacity and to the irradiation facilities
including Neutron Transmutation Doping (NTD) facilities for power semiconductor
production in a large scale and fast neutron irradiation (FNI) facility for
fast neutron irradiation. The NTD and FNI facilities in the KJRR reactor can be
effectively utilized on the study of separated effect of thermal and fast
neutron irradiations on the properties of electro-magnetic materials. HANARO
will also specialize more on irradiation research, including neutron
irradiation of electronic materials. The research status and possibility of new
electro-magnetic materials using neutron irradiation at HANARO are surveyed to
ascertain the utilization of neutron irradiation technology in electro-magnetic
material researches.
