プルトニウム取扱施設非立会検認技術開発とSBD(Safeguards by Design)

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

瀬谷 道夫

Seya, Michio

核燃料サイクルにおける大規模プルトニウム燃料取扱い施設の立場について示すとともに、核燃料サイクル施設で取扱われる核物質の非立会(自動化)技術の基礎となる非破壊測定(NDA)技術の状況を紹介する。その後、大規模な自動化プルトニウム取扱施設(プルニウム燃料第3開発室)の非立会検認技術開発の総括的な紹介を行うとともに、その帰結として、IAEAの加盟各国への基本的な要請となった「保障措置の設計への取入れ」(Safeguards by Design)について触れる。また、IAEA保障措置局・長期R&D計画2012-2023(STR-375)の中での新規施設に関するSBD要請について紹介するとともに、これまでに開発がなされていないFPやMAの混じる高線量核物質に対するNDA技術開発の方向性(アクティブ中性子NDA技術開発)に関して述べる。

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".
