This report describes the status of nuclear seismic safety assurance in Japan before 2007, followed by the background and main achievements of the activities of the three research committees in collaboration with the Japan Association for Earthquake Engineering (JAEE) and the Atomic Energy Society of Japan (AESJ), and finally a summary of the points that the author considers important as the end of these activities.

Thermal striping on the core instrumentation plate (CIP) around the primary control rod (PCR) and backup control rod (BCR) channels and the radial blanket fuel assemblies (RBAs) may be caused. Since the interaction between neighbor areas exists in the UIS and the cold sodium flowing from the RBA is affected by the external flow around the UIS, a spatial connection method consisting of the numerical model for the whole upper plenum and the local target area has been developed. The numerical results were compared with the experimental results to confirm applicability of the method to the practical problem. And, sensitivity of mesh arrangement to the numerical results was discussed by using wide and narrow area models with two different spatial resolutions in each model. Through the examinations, appropriate local model for the spatial connection mothed could be proposed.

Teacher-training programs in corporation with the local Board of Education have been continuously conducted since 2006 by the Kansai Photon Science Institute and Kids' Science Museum of Photons. The obtained results of effect evaluation were summarized on governing key factor. Recently, sufficient degree of effects have been obtained as a regional cooperation project with sustainable activities, from a view point of lectures based on the science-show and the development of the teaching materials.

Design optimization support tool named ARKADIA-Design for diverse nuclear power plant is being developed in Japan Atomic Energy Agency. In the implementation of the numerical evaluation of the plant performance and the design optimization process in ARKADIA-Design, the outline and development status of linkage functions of collecting the necessary information from and storing the results as new knowledge to the databases in the Knowledge Management System are presented.
