In light of recent delay of plutonium use in Japan and the increasing criticism of nuclear non-proliferation and nuclear security in the nuclear fuel cycle, the validity of these criticisms will be examined for the sustainable development of the nuclear fuel cycle policy. Issues on the view point of nuclear non-proliferation and nuclear security are examined.

Strict application of IAEA safeguards and nuclear security should be implemented for Japan's full-scale nuclear fuel cycle. Based on the knowledge and experience of research and development in the nuclear fuel cycle, nuclear material management, the effective and efficient promotion of new technologies should be promoted with scientific and demonstrative measures to strengthen the world's nuclear non-proliferation and nuclear security. Development or sophistication of new technologies, human resource development, and reinforcement of the international framework are future challenge in the international community.

Japan have promoted the peaceful use of plutonium with the nuclear non-proliferation commitment based on IAEA safeguards agreement and Japan-US nuclear cooperation agreement, as well as ensuring transparency of the policy that Japan has no plutonium without purpose of use. In promoting the nuclear fuel cycle, adherence to those measures and maintaining plutonium utilization by means of plutonium-thermal, and a fast reactor cycle to achieve large-scale and long-term energy supply and environmental improvement, therefore, further research and development is essential.

In order to promote the peaceful use of nuclear energy, it is important not only to ensure safety but also to ensure nuclear non-proliferation and nuclear security. Japan has contributed to the international community through strengthening nuclear non-proliferation and nuclear security capabilities with technical and human resource development. However, in the wake of the accident at the Fukushima Daiichi Nuclear Power Plant in 2011, Japan's nuclear power plants have not restarted or plutonium use has not progressed smoothly. Concerns have been shown. Towards appropriate steps of Japan's nuclear fuel cycle policy, such concerns are examined and future efforts are summarized.

Consideration on UK Withdrawal from EURATOM

Tamai, Hiroshi; Tazaki, Makiko; Kitade, Yuta; Shimizu, Ryo; Suda, Kazunori

Nihon Kaku Busshitsu Kanri Gakkai Dai-38-Kai Nenji Taikai Rombunshu (Internet), 6 Pages, 2018/04

The United Kingdom, UK, in March 2017, notified the withdrawal from the European Union, EU. Since EURATOM is managed by the same organisation of EU, the withdrawal from EURATOM is considered to be unavoidable. UK has to define the regulation for the measures covered by EURATOM which include the implementing safeguards in the civil UK nuclear facilities and the nuclear cooperation agreements between EURATOM and third nations. UK experts recognise that such re-arrangements within 2-years are very tough hurdle, so that some alternative measures are proposed by industry side. For peaceful nuclear use in Japan, hindrances on the smooth transfers of nuclear materials and equipment between UK are concerned. This paper will discuss the UK withdrawal from EURATOM focused on the UK's correspondence and the potential influence on cooperation with Japan in view of nuclear non-proliferation.

IAEA low enriched uranium bank; Towards the realization of international management initiatives

Tamai, Hiroshi; Tazaki, Makiko; Suda, Kazunori

Nippon Genshiryoku Gakkai-Shi, 60(1), p.25 - 29, 2018/01

IAEA Low Enriched Uranium Bank, which is one of international management initiatives of nuclear materials operated by IAEA, will be realized soon. During increasing concern on proliferation risk of sensitive nuclear technologies as well as in this century the potential acquisition by terrorists, the IAEA bank will offer the fuel assurance aiming at decreasing incentive for acquiring those sensitive technologies. Throughout the argument on the criteria for the fuel supply, the bank site and its requirement have been established and will be in operation next year. The background, significance, and development of this initiative are described.

The Japan Atomic Energy Research Institute (JAERI) conducts researches and developments related to Comprehensive Nuclear-Test-Ban Treaty (CTBT) on the basis of Japan's pragmatic and progressive efforts toward peaceful use of atomic energy and non-proliferation with the goal of realizing a peaceful and safe world free from nuclear weapons. The Treaty aims for the establishment of a global verification regime comprising an International Monitoring System (IMS) and the JAERI has engaged in the following activities: construction and operation of the radionuclide monitoring stations at Okinawa (RN37) and Takasaki (RN38) and the certified radionuclide laboratory at Tokai (RL11) as specified in Annex 1 of CTBT Protocol, and preparation of the National Data Center at Tokai (JAERI NDC). Research activities of JAERI related to the CTBT verification regime are presented in the paper. The subjects of this presentation are (1) an overview of the CTBT verification regime, (2) construction and operation of RN37, RN38 and RL11, and (3) preparation of the JAERI NDC for radionuclide data.

Conceptual study on synergy effect towards strengthening nuclear safeguards and nuclear security

Tamai, Hiroshi; Kimura, Takashi; Shimizu, Ryo; Tazaki, Makiko; Nakatani, Takayoshi; Suda, Kazunori

no journal, , 

Safeguards-security (2S) complementarity is specified in the areas where the synergistic effects could be expected. Some possibility of joint use of measuring devices is considered. For example, at reprocessing plant, tank level gauges are used for detection of diversion by IAEA safeguards, for detection of theft by state authority, and monitoring operation status by operators. If the specification of sensors (sensitivity, time response, etc.) is satisfied the requirement, they could use the raw data from such sensors jointly. This situation might avoid the duplication of sensor installation and bring cost benefit. Synergistic effect on all types of future nuclear facilities can be expected based on '2S by Design'.
