JAEAとUS-DOEとの協力は、保障措置及び核不拡散技術の研究開発において重要な役割を果たしてきた。協力の成果は、JAEAの濃縮,再処理,MOX燃料製造,先進炉の各施設に適用されてきており、信頼性や費用対効果の面で優れた保障措置システムの構築に大きく貢献をしてきた。加えて、これらの協力により開発された保障措置技術は、統合保障措置への移行においても重要な役割を果たしている。本研究は、20年以上に渡って実施されてきたJAEAとDOEの協力活動を概観するとともに、99件のプログラムを総合的に解析した結果を示す。そのうえで、保障措置のさらなる効率化,透明性,核セキュリティーの向上に向けたDOEとJAEAの今後の協力のあり方を提示する。

Cooperative activities between JAEA and the US-DOE have played a significant role in the research and development of safeguards and nuclear nonproliferation technologies. The achievements of the cooperative activities have been applied to the enrichment plant, reprocessing facility, MOX fabrication facility, and advanced reactors in JAEA. These cooperative activities have contributed substantially to develop reliable and cost-effective IAEA safeguards systems. In addition, the safeguards technologies developed through these activities play an important role when the integrated safeguards is implemented to those facilities and sites. This paper provides an overview of the cooperative activities carried out for over 20 years between DOE and JAEA (JNC/JAERI). This paper also presents a comprehensive analysis of the 99 programs. Finally we suggest potential future cooperative activities between DOE and JAEA for the further enhancement of efficient and effective safeguards, transparency, and nuclear security.
