供給保証に関する国際的な議論に資するために、日本のIAEA核燃料供給登録システム提案をベースとした供給保証システムについて検討した。本稿では、供給保証に必要な追加的なコストと所要期間の想定を行うなど、より現実的なシステムとして実現可能な供給保証メカニズム全体のシステム提案を試みるとともに、供給保証システムに関連する課題を整理しその解決策を示した。主なものは、供給保証の定義,供給保証の対象事由の拡大,「供給保証に関する供給国の宣言」,IAEAでの「供給保証発動諮問委員会」の設置,「供給保証基金」の設置等である。

In order to facilitate the international discussion of the assurance of supply (AOS) system, authors have been conducted studies of AOS. We focused and based our study on Japanese proposal "IAEA Standby Arrangement System (INFCIRC/683)". In this paper, we have been able to show the feasibility of AOS system more specifically by supposing additional costs and the required period necessary for the AOS and present a system we made that we hope as a practical system. And we studied the issues surrounding AOS and presented our proposal of their solutions. The issues we are tackling here are the definitions of AOS; issues on consumer states, supplier states, IAEA and the nuclear industries. The proposals we present here are the broadening the cause of AOS, the declaration of the supplier states on AOS, the advisory committee on the initiation of AOS of IAEA and setting up a IAEA fund for AOS.
