Japan Atomic Energy Agency (JAEA) consulted an assessment committee, "Evaluation Committee of Research and Development (R&D) Activities for Nuclear Safety Research", for post-review and pre-review assessments of Nuclear Safety Research, in accordance with "General Guideline for Evaluation of Government R&D Activities" by Cabinet Office, Government of Japan, "Guideline for Evaluation of R&D in Ministry of Education, Culture, Sports, Science and Technology" and "Regulation on Conduct for Evaluation of R&D Activities" by JAEA. In response to the JAEA's consult, the Committee assessed the results and outcomes of the R&D programs during the 3rd mid-/long-term plan (from April 2015 to March 2022, including the expected results and outcomes) and the validity of the 4th mid-/long-term plan (7 years from FY2022), according to the above-mentioned guidelines. The Committee concluded that the rationale behind the R&D programs, the relevance of the program outcome and the efficiency of the program implementation during the 3rd mid-/long-term plan are comprehensively evaluated as "A", and the R&D programs for the 4th mid-/long-term plan is generally appropriate. This report summarizes the results of the assessment by the Committee. In addition, the appendices of the report contain the responses from JAEA on the comments and suggestions by the Committee and the presentation materials submitted to the Committee.

In response to the directives of the 4th medium-to-long-term objectives, Japan Atomic Energy Agency will formulate the 4th medium-to-long-term plan and run its operation according to the plan from the fiscal year 2022. Consequently, the Sector of Nuclear Safety Research and Emergency Preparedness has reviewed the strategies of the safety research for contributing to the demand, "the continuous improvement of nuclear safety and the effectiveness of nuclear disaster prevention". It was also discussed how to proceed the safety research over the medium-to-long-term plan period based on the proposed new strategies. From the viewpoint of developing human resources and maintaining research capabilities in the sector, discussion was made on measures to pass on the knowledge and skills of senior and mid-career researchers to young researchers. The main elements of the proposed strategies are: (1) to efficiently and effectively develop both problem-solving research and advanced or leading research, considering the importance and needs on the nuclear safety and corresponding to regulatory trends and introduction of new technologies, (2) to produce research results of high quality for social implementation, including proactive proposal of measures for enhancing rationality of nuclear safety and regulation by utilizing risk information, and (3) to promote development of human resources and maintenance of technological base through challenging new research subjects. This report summarizes results of the discussion on the medium-to-long-term safety research strategies and the research plans based on the proposed strategies.

The Committee evaluated the research and development programs and activities of during the period of about three years from April 2015. The Committee evaluated the research and development activities and programs based on the explanatory materials prepared by JAEA and its oral presentations with questions-and-answers sessions. This report summaries the results of the evaluation by the Committee with the Committee report.

The logical adequacy of the safety measures in Monju, coolability of the reactor core and the ex-vessel storage tank by natural circulation, and coolability of the spent fuel storage pool, considering Tohoku district - off the Pacific Ocean Earthquake were explained by Japan Atomic Energy Agency and reviewed in the above-titled committee. Main conclusions by the chairman of the committee are summarized as follows: (1) Natural circulation cooling is secured in the reactor after station blackout (SBO) as far as flow path exist. Therefore, the reactor core will never melt because of the decay heat removal as far as the natural circulation is reserved after the reactor shutdown; (2) Spent fuels will never melt due to temperature rise in the ex-vessel fuel storage system, since natural circulation cooling can be expected even after SBO; (3) It is possible to take sufficient countermeasures such as water supply against the spent fuel pool because it takes approximately two month before the top of the spent fuel cans which contain spent fuels are exposed by evaporation of the water.

The Third International Symposium on Radiation Education was held on August 23-26, 2004 at Nagasaki, Japan. The fundamental knowledge of radiation and related nuclear matters should be properly communicated to students and general public. The symposium has been devoted to developing an effective method of radiation education. To remove unnecessary fears for radiation and to utilize radiation and nuclear energy to contribute to the human welfare, the spirit of radiation education was first announced internationally in 1998 at Hayama, Japan, and then confirmed in 2002 at Debrecen, Hungary, and now was reassured in August 2004 at Nagasaki. The symposium consisted of 5 sessions with 77 submitted papers, and involved 141 participants from 13 countries.
