M. Narui et al., DEVELOPMENT OF RIG FOR FUNDAMENTAL-STUDY OF RADIATION EFFECTS ON FUSION MATERIALS IN JMTR, Science Reports of the Research Institutes, Tohoku University, Series A: Physics, Chemistry, and Metallurgy, 40(1), 1994, pp. 167-171
The accumulated results of radiation effects on materials have clearly
shown that temperature history is very important for the evolution of
microstructures induced by irradiation. Japan Materials Testing React
or, has several preferable features for the temperature controlled irr
adiation. Two kinds of techniques were applied to control the irradiat
ion temperature. The control of thermal insulation along with heating
by the electrical heater, which is the other technique of the temperat
ure control, permits us to control the temperature in the range of 360
-1100K, regardless the reactor is in the operation or out of the opera
tion.
