As a group of experts of the nuclear science and technology, AESJ (Atomic Energy Society of Japan) realized responsibility for a nuclear-power disaster, and participated in the convergence of the accident and an environmental remediation since the outbreak of the accident positively and worked on activity in order to achieve the duty. As the part, AESJ started "investigation committee about the Tokyo Electric Power Fukushima the first Nuclear Power Plant accident" (2012) on June 22 in 2012. The committee gathered from divisional meetings and liaison meetings, the committee which constituted a society and pushed forward activity. AESJ stands in the reflection that was not able to prevent this accident as a scientific group of experts of the fields of atomic energy, and, separately from various accident investigation of the above, deep analysis investigates an accident phenomenon and the influence from a specialized viewpoint.

Japan Atomic Energy Society made investigation of the cause for the accident of the Fukushima Daiichi Nuclear Power Station of Tokyo Electric happened in March 11, 2011. Although the accident of this Fukushima Daiichi was caused by natural disasters, it shows how a similar event could be generated by sabotage, and the importance of this point was recognized as well as safety measures from the nuclear security side. This paper describes the results of the investigation and discussion on the part of Nuclear Security / Physical Protection and Safeguards / nuclear material accountancy.

Recent development of fusion reactor technology in Japan is summarized. ITER is a fusion experimental reactor that will play a central role in fusion reactor development in near future. Plasma technology has been focused on exploitation of the ITER operation basis. Long sustainment of high normalized beta discharges performed in JT-60U is a good example of research contributing to ITER. As to fusion engineering, there was remarkable progress in the manufacturing methods of superconducting magnets, and in a high (1 MW), efficient (55%) and long (800 seconds) power generation of 170 GHz radio-frequency waves, which would also contribute to the construction of ITER. The article contains an overview of the Broader Approach program which has been carried out in parallel with the ITER project, as well.

The goal of broadening industrial applications of nuclear energy while significantly cutting CO
emission can be achieved with the near-term deployable, passively-safe high-temperature gas-cooled reactors (HTGRs), which can supply heat of high-temperatures of up to 950
C to a wide range of industrial plants for CO-free hydrogen production, power generation, etc. This paper introduces technical features of HTGR and the current status of HTGR developments worldwide with emphasis on the R&D activities conducted by Japan Atomic Energy Agency (JAEA). JAEA as the center of excellence on R&D of the HTGR system in Japan, which leads the world R&D on HTGR and nuclear hydrogen production technologies, has successfully carried out the reactor passive safety demonstration and most recently the 50-day high-temperature operation test by using the High Temperature Engineering Test Reactor (HTTR) of 30 MWt. Based on the test results obtained in the HTTR, a commercial power generation system with gas turbine and an advanced system cogenerating electricity by the gas turbine and hydrogen by a thermochemical method have been designed. This paper concludes by giving a perspective of future HTGR developments.

The information explosion resulting from modern technology is identified as a critical problem for deep geological disposal of high-level radioactive waste (HLW). A paradigm shift is needed in the basic concept for information management. This recognition had led to the development of a next generation Knowledge Management System (the JAEA KMS) that makes maximum use of recent developments in Information Technology (IT) and the methodology of Knowledge Engineering (KE) as applied in other technical fields. This paper provides a brief outline of the design concept of the JAEA KMS and then overviews recent progress towards development of an operational system.

In order to enhance safety of fusion reactor, JAEA investigates effective tritium removal system in case of incidental tritium release in the building. Recently, we paid attention to the bacteria, which had an ability of hydrogen oxidation at room temperature, and a new effective detritiation system using the bacteria has been studied under the collaboration with Ibaraki University, instead of catalytic oxidation reactor of rare metal.
