The Collaborative Laboratories for Advanced Decommissioning Science (CLADS), Japan Atomic Energy Agency (JAEA), has been conducting the Nuclear Energy Science & Technology and Human Resource Development Project (hereafter referred to "the Project") from FY2019. The Project aims to contribute to solving problems in the nuclear energy field represented by the decommissioning of the Fukushima Daiichi Nuclear Power Station (1F), Tokyo Electric Power Company Holdings, Inc. (TEPCO). For this purpose, intelligence was collected from all over the world, and basic research and human resource development were promoted by closely integrating/collaborating knowledge and experiences in various fields beyond the barrier of conventional organizations and research fields. The sponsor of the Project was moved from the Ministry of Education, Culture, Sports, Science and Technology to JAEA since the newly adopted proposals in FY2018. On this occasion, JAEA constructed a new research system where JAEA-academia collaboration is reinforced and medium-to-long term research/development and human resource development contributing to the decommissioning are stably and consecutively implemented. Among the adopted proposals in FY2024, this report summarizes the research results of the "Data-driven on-site diagnostic technology: predicting microbiologically influenced corrosion risk for ensuring long-term integrity" conducted in FY2024. The present study aims to establish an innovative on-site diagnostic protocol capable of predicting microbiologically influenced corrosion (MIC) risks with high accuracy. To achieve this, we combined high-throughput analytical methods, simulated field experiments, and data-driven statistical analyses. Environmental samples were collected in Fukushima Prefecture to characterize microbial community structures and to develop key technologies for on-site genetic diagnostics. Using these samples, we evaluated the iron-corroding potential under various culture conditions and designed experimental systems simulating 1F environment. A high-throughput testing framework was validated for its ability to measure actual iron corrosion. In parallel, statistical approaches integrating microbial community profiles with MIC activity data were applied, yielding useful insights into both their applicability and limitations. Further, fixation methods for microbial observation in corrosion samples were examined, and optimal conditions were identified. Overall, the project provided valuable information on environmental microbial communities, cultivation of corrosion-associated microorganisms, and data-driven statistical approaches. These results lay the groundwork for the development of biomarker-based, ubiquitous diagnostic technologies for MIC applicable to diverse field environments, including those around 1F site.

Among the adopted proposals in FY2024, this report summarizes the research results of the "Development of a radiation resistant laser scanner and 3D modeling method using AI and image processing" conducted in FY2024. This research focuses on developing a radiation-resistant 3D laser scanner and technologies to enhance the quality of point cloud data. A new scanner system was designed with a laser scanning head composed only of radiation-tolerant electrical and mechanical components, excluding semiconductors, and a control unit placed remotely in a low-radiation zone. The system aims to enable stable scanning in high-radiation environments. Its performance will be evaluated in comparison with commercial scanners. To address the sparsity of acquired point clouds, we are developing two complementary systems: one uses machine learning to complete and enhance point clouds through processes such as denoising, normalization, and interpolation; the other uses photogrammetry to reconstruct 3D data from image sets and integrate it with scanner-derived data. In FY2024, (1) Optical and electronic circuits were designed and assembled, and waveform collection and analysis software was developed to prepare for scanner detection efficiency evaluation. (2) A point cloud completion system incorporating AI was implemented, and methods for point cloud densification and completion were investigated. (3) A processing environment and workflow were established to integrate point clouds with photogrammetry, and 3D surface models were constructed. (4) Efficient scanning strategies under high-radiation conditions were analyzed, and a methodology for accuracy evaluation was studied. (5) The project was advanced through close coordination among research components and related institutions.

After the Tokai Reprocessing Plant (TRP) has received approval for its decommissioning plan in June 2018 and transferred to the decommissioning stage, it still remains an amount of high active liquid wastes. Because it takes a considerable amount of time to complete the vitrification of the high active liquid wastes, and because the plant is located near the Pacific coast and is at risk from earthquakes and tsunamis, appropriate Safety Measures were implemented in accordance with the present risks on TRP and the upgraded regulatory standards which was revised in July 2013 based on lessons learned from TEPCO's Fukushima Daiichi Nuclear Power Station accident in 2011. Most of the radioactivity inventory in the TRP is involved in the high active liquid waste and these wastes are stored in two facilities. The high active liquid wastes have a relatively high decay heat, and therefore there is a risk of releasing radioactive materials outside the facility due to leakage or boiling. In addition, since the location of TRP is near the Pacific coast and there is a risk of earthquakes and tsunamis. Thus, for the two facilities which treat the high active liquid waste, the High Active Liquid Waste Storage Facility (HAW) and the Tokai Vitrification Facility (TVF), we decided to enhance those safety features in line with the upgrade regulatory standards. The notable safety measures include ground reinforcement work and exhaust pipe reinforcement work to improve earthquake resistance, installation of tsunami debris protection fences as a tsunami countermeasure, installation of protective doors against tornado debris, setting of wildfire prevention line, and strengthened measures against internal fires and internal flooding events. These construction works began in July 2020 and were completed in five years, by March 2025. Those provide great improvement in the safety of TRP for future vitrification processing.

Times Cited Count：0 Percentile：0.00(Engineering, Biomedical)Several Monte Carlo Track-Structure (MCTS) codes for liquid water have been developed worldwide over the last 40 years; however, use the different interaction cross sections. This study evaluates the uncertainties of physical features (electronic stopping power, pathlength, dose-point-kernel, and microdosimetry) of low-energy electron transport in liquid water by using 6 types of MCTS codes. The intercomparison results reveal significant differences among MCTS codes at low energies, especially below ~100 eV, potentially compromising the accuracy of DNA damage simulations where such electrons play a key role. The present work highlights the need for further development of the physics models used in MCTS codes to reduce the uncertainties associated with low-energy electron transport calculations in liquid water.
