"R&D Project on Irradiation Damage Management Technology for Structural Materials of Long-life Nuclear Plant" was carried out from FY2006 in a fund of a trust enterprise of the Ministry of Education, Culture, Sports, Science and Technology. The coupled irradiations or single irradiation by JOYO fast reactor and JRR-3 thermal reactor were performed for about two years. The irradiation specimens are very important materials to establish of "Evaluation of Irradiation Damage Indicator" in this research. For the acquisition of the examination specimens irradiated by the JOYO and JRR-3, we summarized about the overall plan, the work process and the results for the study to utilize these reactors and some facilities of hot laboratory (WASTEF, JMTR-HL, MMF and FMF) of the Oarai Research-and-Development Center and the Nuclear Science Research Institute in the Japan Atomic Energy Agency.

We are proceeding with the study of "R&D Project on Irradiation Damage Management Technology for Structural Materials of Long-life Nuclear Plant". For the study, it is important that the irradiated specimens are gotten by the coupling of JRR-3 and JOYO. This reports the total irradiation plan in the study, and the executed work for the coupling irradiation (JRR-3 and JOYO) including the Hot facilities work of Tokai and Oarai in the 2006 fiscal year.

In previous studies, although a tendency for voids to form around dry recovered powder particles has been observed from the metallography of sintered pellets, it has been difficult to completely distinguish the areas derived from dry recovered powder particles from those derived from raw powder. In this study, for the purpose of clarifying the mechanism of the control of the pellet sintering density by dry recovered powder, and to identify the area in the sintered pellets derived from simulated dry recovered powder, (Ce,Zr)O sintered pellets with zirconium oxide (ZrO) added as a tracer in CeO was milled and particle size adjusted to obtain (Ce,Zr)O simulated dry recovered powder was used as a parameter for the particle size distribution and the mixing ratio of CeO raw powder and simulated dry recovered powder to form and sintered pellets, and the microstructure of the pellets was evaluated.
