Safeguards implementation at KAERI

摘要

The aim of safeguards is to ensure that there is no diversion of the nuclear material from peaceful uses to military uses. To attain this goal more effectively and efficiently, the IAEA develops new technology and equipment with optimum cost-effectiveness in implementing safeguards under Integrated Safeguards (IS). Since IS entered into force in 2008, the Korea Atomic Energy Research Institute (KAERI) has been making every effort to establish a facility-level safeguards system in light of this change. First, KAERI needed to build a system that provides near real-time accounting information to the inspectors during Random Interim Inspection (RII). To comply with this requirement, KAERI developed a new system, called, KASIS, (KAeri Safeguards Information Treatment System). This system enables the facility operator to deliver accounting information concerning nuclear materials subject to safeguards on a timely basis. After the loss of nuclear material in 2007, there have been many changes such as a broader conclusion and integrated safeguards. In return for IS agreements, IAEA reduced the inspection. To assure the transparency of nuclear activities, however, the state regulatory body (KINAC) has a little increased the domestic inspection, and KAERI has increased the internal Self-PIT on a quarterly basis to strengthen the implementation of facility level safeguards approach. KAERI has 11 major nuclear facilities subject to safeguards such as a multipurpose research reactor, two irradiation examination facilities, a fuel fabrication facility for a research reactor, R&D facilities with 17 KMPs, and a LOF with 11 laboratories. This paper describes how to implement facility level safeguards approaches at KAERI. In particular, this is to share its experience related to the implementation of Integrated Safeguards with the newcomers of a nuclear facility, as well as with other facility operators interested in safeguards implementation.
