The PSTEP is a nationwide research collaboration in Japan and was conducted from April 2015 to March 2020, supported by a Grant-in-Aid for Scientific Research on Innovative Areas from the Ministry of Education, Culture, Sports, Science and Technology of Japan. It has made a significant progress in space weather research and operational forecasts, publishing over 500 refereed journal papers and organizing four international symposiums, various workshops and seminars, and summer school for graduate students at Rikubetsu in 2017. This paper is a summary report of the PSTEP and describes the major research achievements it produced.

President of Japan Atomic Energy Agency consulted with the "Evaluation Committee of Research Activities for High-Temperature Gas-Cooled Reactor and Related Hydrogen Production Technology" (hereinafter referred to as "Evaluation Committee"), which consists of specialists in the fields of the evaluation subjects of high-temperature gas-cooled reactor and related hydrogen production technology. The evaluation concludes that an overall judgment is A, because the outcome of the 2nd midterm plan has been obtained as planed in terms of advancing the safety and the practical use in each of the high-temperature gas-cooled reactor technology and the hydrogen production technology. As a result the technological goal has been achieved. Another key outcome obtained is that the achievement for a part of the next midterm plan has been accelerated with the construction of a continuous hydrogen production test facility. In addition, the contents of the 3rd period mid- to long- term plan (draft) are acceptable because they sufficiently reflect the interim report of the high-temperature gas-cooled reactor technical research and development working group organized by the MEXT. This report lists the members of the Evaluation Committee and outlines the method and procedure of the assessment. The results of the assessment by the Evaluation Committee are attached from Page 7.

This report present the regional and detailed geological study and shallow drilling programs of the Neogene basins in the Horonobe-cho for the Horonobe Underground Research Program at Horonobe-cho, Hokkaido by the Japan Nuclear Cycle Development Institute.The data obtained from the deep drill-holes near the site of the Underground Research Laboratory have not been clearly correlated with the surface geological data from regional area and even the area around the site of the Underground Research Center. Therefore, the purpose of this study is to confirm the regional geology and detailed local geology confined the site of Underground Research Laboratory, and to understand the geological characteristics of the Omagari fault that passes through the west part of Horonobe-cho.
