"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.

In the Ningyo-Toge Environmental Engineering Center, we clarify a relation of all works about the decommissioning. And, as an information base to plan promotion of efficiency of a work, we develop the Decommissioning Engineering System. The Decommissioning Engineering System consists of the function to do work support of a decommissioning, the function to gather the results information the decommissioning technology and the general evaluation function of the decommissioning plan on the basis of facilities information collected by three-dimensional CAD. The decommissioning of the nuclear fuel cycle facility has the characteristics that a period from the plan to the decommissioning is long in comparison with the general chemical plant. And the peculiarity to handle radioactive waste is a reason. In addition the System Decontamination, Dismantling, Treatment and Waste disposal are each other influence it closely in the decommissioning process. Therefore as for the decommissioning process, system engineering is important.
