23. Preparation and Detection of “Mock” Debris Targets for Isotope Analysis of Debris from the Fukushima Daiichi Nuclear Power Plant toward Its Decommissioning

Taiki Tanaka (Japan Atomic Energy Agency)

31/08/2026, 15:20

It has been 15 years since the Fukushima Daiichi nuclear power plant accident, and we are still working
toward our mission of achieving safe decommissioning, which is expected to require approximately 40 years. One of
the most difficult challenges is the presence of approximately 880 tons of nuclear fuel debris in the reactors that melted
during the accident. Key questions include: (1) how...

45. NONDESTRUCTIVE EVALUATION TESTING FOR SELENIUM-75 PRODUCTION TARGETS IN THE HIGH FLUX ISOTOPE REACTOR

Mikayla Duggan (Oak Ridge National Laboratory)

Selenium-75 (⁷⁵Se) is one of dozens of radioisotopes produced at Oak Ridge National Laboratory (ORNL) to support the US Department of Energy’s Office of Isotope R&D and Production. The isotope is produced by irradiating enriched ⁷⁴Se target material in the High Flux Isotope Reactor (HFIR). ⁷⁵Se has a half-life of 120 days and is used as an industrial gamma...

54. TARGETRY FOR LASER DRIVEN INERTIAL FUSION ENERGY (IFE)

Dr Gabriel Schaumann (Technische Universität Darmstadt)

31/08/2026, 16:00

Focused Energy is developing laser-driven Inertial Fusion Energy (IFE) technology aimed at enabling commercially viable fusion power generation. Our approach combines high-efficiency lasers, advanced target design, and scalable reactor engineering to address the key challenges on the path toward continuous, high-repetition-rate fusion energy production. This presentation will outline the...

20. Mesurement of the lifetime of carbon stripper foils based on the LEAF facility

Mr Zhiyou Xu (Institute of Modern Physics, Chinese Academy of Sciences, Lanzhou, China; School of Nuclear Science and Tech-nology, University of Chinese Academy of Sciences, Beijing, China)

31/08/2026, 16:20

To achieve higher acceleration efficiency, carbon foils will be utilized to strip the pre-accelerated ions from iLinac and then the stripped ions will be injected into the Booster Ring (BRing) at the High Intensity heavy ion Accelera-tor Facility (HIAF) [1]. Considering the impacts of high energy deposition of heavy ions and extremely high beam intensity, the foils face severe lifetime...

24. Toward In-situ Temperature Diagnostics of Charge-Exchange Stripping Foils under High-Power Operation: Feasibility Study Based on Offline Experiments and Operational Experience at the J-PARC RCS.

Masahiro Yoshimoto (Japan Atomic Energy Agency / J-PARC center)

31/08/2026, 16:40

The J-PARC RCS has achieved 1 MW beam operation using pure carbon stripping foils instead of hybrid boron-doped carbon (HBC) foils. Although the temperature rise is estimated to be on the order of 1000 K under current conditions and does not yet limit operation, it is expected to become a critical factor for future higher-power upgrades.
　This study presents a feasibility study of temperature...

39. OPTIMIZATION OF CHROMATOGRAPHIC SEPARATION FOR AC-225 PRODUC-TION AT RAON TOWARD RADIOACTIVE WASTE MINIMIZATION

Hye Jin Cho (Institute for Basic Science)

Actinium-225 (Ac-225) is a promising alpha-emitting radionuclide for targeted alpha therapy (TAT) in cancer treat-ment, driving increasing demand for its reliable production. Accelerator-based production using thorium targets has emerged as a viable route. In particular, the RAON (Rare isotope Accelerator complex for ON-line experiments) pro-vides a facility-relevant platform for...
