SUMMARY OF THE VARYING TEMPERATURE IRRADIATION EXPERIMENT IN HFIR

摘要

The Varying Temperature Irradiation Experiment in the High Flux Isotope Reactor (HFIR) was carried out in the framework of the Japan-USA fusion cooperation program (JUPITER). The objective of the experiment is to investigate the performance of fusion structural materials subject to temperature variation during operation. The experiment will also contribute to re-examining the available fission reactor irradiation data including temperature transient. The irradiation for the experiment was performed from July 1998 to May 1999. Some results of the Post-Irradiation Examination are now available. This paper summarizes the highlights of the experimental results and insights obtained through the experiment about the temperature variation effects on materials performance under irradiation.
