Effective capacity-building development based on good practices from the additional protocol implementation

Rodriguez, P.; Senzaki, Masao; Sekine, Megumi

Proceedings of INMM 60th Annual Meeting (Internet), 9 Pages, 2019/07

The ISCN of the JAEA has been providing assistance, specifically to Asian countries, for the past 8 years, since its establishment in 2010. The ratification of the Protocol Additional (AP) to the safeguards agreement, had involved some changes in the Asian countries resource infrastructures to adhere with the respective States obligations on nuclear non-proliferation. During the 7th FNCA workshop held in Mito, Japan in September 2017, under the Nuclear Security and Safegaurds Project (NSSP), a 3-year plan on the formulation of a generic set of Fundamentals on the Implementation of the Additional Protocol was proposed. To formulate this set of fundamentals, there was a need to prepare a set of Examples of good practices on the implementation of the AP based on the FNCA members experience. The ISCN was tasked to prepare the template and conduct the needed survey among the FNCA members of the project on nuclear security and safeguards. This paper provides a preliminary summary and analysis of the responses received. This paper presents the analysis of the good practices that were implemented in order for the States to satisfy the requirements of the IAEA, as stipulated in the AP. The nuclear fuel cycle characteristics of the involved Asian countries are quite different in several aspects, thus entailing a diverse strategy in resource infrastructure development. This paper describes how every country may have different approaches towards achieving the same objectives. It is worthwhile to look into these various practices, find commonality and share the experience. The objective of formulating a set of fundamentals on AP implementation will be achieved through a compilation and analysis of good practices and shared experiences among its members. The preliminary result on this project was introduced at the 8th FNCA workshop held in Beijing, China in September 2018.

Effective use of inspection samples as intercomparison samples for the quality control in safeguards analysis in Japan

For the effective and efficient implementation of international Safeguards it is essential that the Operator's measurement system is maintained at a level of high quality and improved, as necessary. Besides the internal quality control, it is important to have elements of Quality Assurance (QA) in place, such as external intercomparison. However, there were no intercomparison programs with Pu samples available in Japan because of very few users and difficulties in the shipment. To cope with this situation, intercomparison by using actual safeguards samples containing Pu and U was started. Inspection samples are selected and prepared for shipment to the Safeguards laboratories together with other samples. Safeguards laboratories receive and analyze them as inspection samples as well as intercomparison without additional cost. The practicality and effective use of this DA intercomparison, which is operated since more than 20 years, will be explained.
