放射性同位元素（RI）は，その多くが研究用原子炉や加速器で製造され，工業分野や医療分野等への活用により国民生活の向上に大きく貢献している。今後も研究用原子炉を用いたRI製造・頒布は重要とされており，「もんじゅ」サイトに建設計画中の新試験研究炉でもRI製造が期待されている。本稿では，新試験研究炉でのRI製造の検討に資すべく研究用原子炉JRR-3を利用したRI製造の取り組みを紹介する。
Many radioisotopes (RI) are produced in research reactors and accelerators, and are making a significant contribution to providing better lives to people through their use in the industrial and medical fields. RI production and distribution using research reactors will continue to be important, and RI production is expected to take place in the new research reactor currently being planned for construction at the Monju site. This article introduces efforts of RI production using the research reactor JRR-3 to contribute to the consideration of RI production in the new research reactor.
Key words: radioisotopes (RI); research reactor; JRR-3; Monju site
