Development of unattended safeguards verification systems for plutonium handling facilities and SBD (Safeguards by Design)

Seya, Michio

This presentation explains at first the position of the large scale plutonium handling facility in the nuclear fuel cycle and the situation of technology development of non-destructive assay (NDA) as basis of unattended safeguards verification of nuclear materials handled in the cycle. Then the presentation explains the summary of the development of the unattended safeguards verification systems at PFPF of JAEA and IAEA's request for "SBD (Safeguards by Design) to member states as an end. Then it explains that SBD for new types of facility is included in "IAEA Department of Safeguards Long-Term R&D Plan, 2012-2023 (STR-375)". Also it explains about the direction of the technology development of NDA for high radiation nuclear material (HRNM), "nuclear material with fission products and minor actinides, need to go to the development "active neutron NDA technologies".
