Irradiation Experimental Facilities, the Oarai Branch of Institute for Materials Research of Tohoku University, has attained the 20th anniversary since their foundation. The facilities were established in 1969 as joint-use facilities in order that researchers mainly from national universities all over Japan may perform fundamental studies for the developments of nuclear reactor materials and nuclear fuels by using the Japan Materials Testing Reactor (JMTR ) of Oarai Research Establishment, Japan Atomic Energy Research Institute (JAERI). At present, researchers are conducting actively extensive studies concerning nuclear reactor materials by using JMTR and also the fast experimental reactor, JOYO, of Oarai Engineering Center, Power Reactor and Nuclear Fuel Development Corporation (PNC). Materials being studied include a great variety of metals, ceramics and others. Effects of neutron irradiation on the microstructure and mechanical and physical properties of these materials are being examined and the development of nuclear reactor materials are being conducted. In particular, the development of materials for a nuclear fusion reactor called Queen Technology" is required strongly, since the development of this sort of reactor as a final energy source of mankind has come realization of the International Thermonuclear Experimental continuous and steady efforts. Accordingly, most irradiation up to the stage of the Reactor (ITER) with studies by using our facilities are currently devoted to basic research for the fusion reactor materials development and the irradiated specimens by using Hanford's Fast Flux Test Facility (FFTF) according to a Japan-U.S. collaboration are being carried in the facilities. Thus, they play a role of base facilities for heavy irradiation research in Japan. Joint-use research of actinide materials has begun in 1989 in the facilities. In memory of the 20th anniversary from the foundation of our facilities, we continue an effort of publication of a collection of original or review papers on studies made so far by Japanese university researchers using the facilities at intervals of 2 years. Upon the publication, we extend our heartfelt gratitude to the stuff members of both the JAERl Oarai Research Establishment and the PNC Oarai Engineering Center.".
