Nuclear security culture in comparison with nuclear safety culture; Resemblances and differences

Kawata, Norio

Kaku Busshitsu Kanri Gakkai (INMM) Nihon Shibu Dai-36-Kai Nenji Taikai Rombunshu (Internet), 7 Pages, 2015/12

Since the terrorist attacks on the U.S. on September 11th,2001, Nuclear Security has been focused on and treated as a global issue in the international community and it has also been discussed as a real and serious threat to nuclear power plants in the world since The Great East Japan Earthquake in March, 2011. The International Atomic Energy Agency (IAEA) issued a document including Nuclear Security Recommendations (INFCIRC/225/Rev.5) (NSS 13) in the Nuclear Security Series and emphasized the necessity of fostering Nuclear Security Culture. Nuclear Security Culture has been frequently discussed at various kinds of seminars and events. Since the officials in charge of Nuclear Security are familiar with the area of Nuclear Safety, the relationships between Nuclear Safety Culture and Nuclear Security Culture have been the point in controversy. This paper clarifies relevance between Nuclear Safety and Nuclear Security, considers resemblances and differences of their concepts and lessons learned for each culture from nuclear power plant accidents, and promotes deeper understanding of Nuclear Safety and Nuclear Security Culture.

Evaluating methods to improve safeguards training courses of ISCN

Okumura, Yukiko; Nakamura, Yo; Kawata, Norio

Kaku Busshitsu Kanri Gakkai (INMM) Nihon Shibu Dai-35-Kai Nenji Taikai Rombunshu (Internet), 8 Pages, 2015/01

Although questionnaires were used to receive feedbacks from participants at the end of each training course, Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN) of Japan Atomic Energy Agency (JAEA) did not establish a structured evaluation method. To this end, ISCN has started to study on methods to accurately evaluate the courses since April and started to introduce the evaluation method on trial, according to the Donald Kirkpatrick's Four-Level Training Evaluation Model, so as to better develop and conduct more effective courses. This paper will focus on how ISCN has modified the Kirkpatrick's Four-level to adapt to its safeguards training courses. This will then be followed by two particular cases of how the evaluation method functioned for the Additional Protocol training courses held in Malaysia in 2014, and the feedbacks received to improve future training courses.

Kawata, Norio; Wakabayashi, Shuji; Hanai, Tasuku; Yamaguchi, Yasuo; Nonaka, Nobuyuki; Scharmer, C.*

Proceedings of International Conference on Nuclear Security; Enhancing Global Efforts (CD-ROM), 10 Pages, 2014/03

The ISCN of the JAEA provides effective trainings in order to strengthen nuclear security for emerging nuclear power countries in Asia to realize Japan's National Statement at the Washington Nuclear Security Summit in April 2010. As a part of these activities, the ISCN has developed the PPEF and the VR training system, which are training tools to implement experience-oriented and interactive lessons. These two facilities are mutually complemented and contribute to deeper understandings through actual practices in addition to the classroom lesson. The ISCN initiated its full-scale training from 2012 JFY, and these two facilities received more than 450 trainees or vistors from Japan and over-sea countries. This paper provides the basic concepts and outlines of these two facilities and the training programs that use them for teaching the nuclear security.

Kaku Busshitsu Kanri Gakkai (INMM) Nihon Shibu Dai-34-Kai Nenji Taikai Rombunshu (Internet), 4 Pages, 2013/10

In order to support international safeguards activities conducted by the IAEA, the Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN) of the Japan Atomic Energy Agency (JAEA) has been providing the International Training Course on State Systems of Accounting for and Control of Nuclear Material (SSAC) targeted mainly at Asian nations as a Japan's subsidized project by making good use of Japan's efforts and experience in nonproliferation. The course provides the opportunity of a facility tour and an A-bombed site visit, as well as offers lectures and practical trainings necessary to build and maintain the SSAC for those including "government officials involved in safeguard policy and regulation" and "business operators engaged in accounting". This paper discusses the summary of the SSAC training course operation held at the ISCN.

Kaku Busshitsu Kanri Gakkai (INMM) Nihon Shibu Dai-33-Kai Nenji Taikai Rombunshu (Internet), 6 Pages, 2012/10

The Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN) of the Japan Atomic Energy Agency set up exercise facilities for trainee of nuclear power emerging countries in Asia involved in Physical Protection (PP) including government officers in charge of nuclear security policy or nuclear security regulation, planning and management staff of PP facilities of operating companies, design professionals for PP facilities, and security personnel responsible for PP. After April in 2012, the facility started to be applied to actual ISCN's PP training and is expected as training field for not only Asian nuclear emerging country but also domestic nuclear energy companies and regulatory bodies. In order to provide effective and practical exercises, we set up the training facilities with basic measures and equipment typical of those used in actual PP facilities, e.g., protective fences, sensors, and cameras. This paper provides an outline of the facilities.

Russian Surplus W-Pu was produced by byproducts of disarmament of nuclear weapon and recognized as a serious threat of nuclear proliferation. US and RF concluded an agreement to dispose of no less than 34 ton-Pu each in 2000. G7 countries including Japan jointed to collaborative investigation to dispose of Russian W-Pu. Relative countries have been discussing the scenario of Pu disposition mainly by burning in LWR (VVER1000) with MOX pellet fuel and FR (BN600) with MOX vipac fuel, however actual disposition work faced dead lock since estimated necessary cost is more than 3 times of pledged finance by G7 countries. JAEA has conducted to realize BN600 vipac fuel option, which is MOX vipac fuel made with W-Pu is burned in BN600 reactor, based on experiences of Pu utilization and fast reactor technology in a decade years. Technical feasibility is established through several cooperative studies with Russian Institutes. Since this option is confirmed as a low-cost and early disposition method, recently, US and RF seek to accelerate this option prior to VVER1000 option. This paper will provide a description of progress on BN600 vipac fuel option and future prospects of whole plan of Russian Surplus W-Pu disposition of 34 ton.

Kawata, Norio

no journal, , 

As for the Disposition of Russian Surplus Plutonium dismantled from nuclear weapons, the irradiation method using light-water nuclear reactor (VVER1000) of Russia (Plu-thermal option) has been recognized as a major method. However at the U.S.-Russia conference in recent years, the fast reactor (BN600 etc.) option that had used the MOX Vibro-packed fuel was decided to apply to Russian Plutonium disposition. This technology is what the JAEA promotes it by a joint research with Russia, and JAEA will reports on the status of technical support, cooperation for the fast reactor option, and a recent trend.
