JMTR-HLでは、今後の照射ニーズに対応した照射後試験の高度化を進め、世界共通研究課題である軽水炉長期化対策、次世代軽水炉の開発や医療用ラジオアイソトープ製造技術の開発など「グリーン・イノベーション」や「ライフ・イノベーション」を支える研究環境を実現する目的で原子力エネルギー基盤研究の位置付けを構築し、国際的研究開発の拠点化の達成を目指して文部科学省の「最先端研究基盤事業」とし選択された照射後試験設備の整備を進めてきた。本整備においては、透過電子顕微鏡(TEM: Transmission Electron Microscope)、集束イオンビーム加工装置(FIB: Focused Ion Beam)及びX線光電子分光装置(XPS: X-ray Photoelectron Spectroscopy)などを設置し、放射能量30MBq(コバルト換算)の照射済材料試験片の加工、試料観察を可能にした。

JMTR-HL has been promoting the advancement of PIE meets future needs of irradiation, and has been constructing the position of basic research of nuclear energy for the purpose of realizing a research environment to support "Green Innovation " and "Life Innovation" such as measures for prolonged LWR that is a subject for study worldwide, development of Next Generation LWR, the development of radioisotopes manufacturing technology for medical use, and has been promoting the development of post-irradiation test facility that is selected by the Ministry of Education as "Cutting-Edge Research Infrastructure Projects" toward the achievement of a base for international R&D. This development has done TEM, FIB and XPS, etc. and have enabled the processing and the sample observation of irradiated material specimen of 30 MBq amount of radioactivity (in terms of cobalt).
