Times Cited Count：4 Percentile：29.2(Nuclear Science & Technology)In the Japan Atomic Energy Research Institute (JAERI), in-pile strain measurement techniques have been developed using the Japan Materials Testing Reactor (JMTR). In order to evaluate the performance of fiber optic grating sensors under irradiation environment, heat-up and performance tests at elevated temperatures before irradiation and in-pile tests were performed in JMTR. It was determined that it is possible to measure strain under irradiation environment below 1
1023n/m
(E
1MeV) by a fiber optic grating sensor, because in-pile temperature characteristics were in good agreement with out-of-pile test results.

A high fast neutron irradiation field with the enough irradiation volumes for para-metric irradiation is needed for the development of nuclear grade structure material. The experimental fast reactor "Joyo" is an available only fast neutron irradiation field in the OECD countries. The MK-IV core will have the maximum fast neutron flux (E 0.1 MeV) of 10
n/cms. This is a high-level fast neutron flux of the irradiation test facilities in the world. Joyo can further enhance its capabilities by tailoring neutron spectrum, decreasing or increasing the irradiation temperature. For an experiment, it is important to evaluate neutron flux, dpa and temperature. Joyo provides accurate evaluation of irradiation conditions based on calculations verified by previous characterization tests and measurement using dosimetry technique. It's expected to utilize "Joyo" for the various purposes as well as irradiation of fast reactor development.
