For enhanced safety, economic efficiency, and reliability of large-scale structures.

For large and complex facilities such as nuclear power plants, it is crucial to detect and evaluate equipment degradation at an early stage by identifying which components are affected and quantifying the extent of any deterioration.

With these challenges in mind, our laboratory is dedicated to developing technologies for assessing and monitoring the integrity and reliability of nuclear structures. Our goal is to enhance the safety of nuclear energy and thereby contribute to a more stable and economically viable energy supply. Research activities in our group include developing advanced measurement techniques, probes, signal processing algorithms, numerical simulation methods, and inverse analysis approaches for detecting and quantitatively evaluating degradation, such as within piping systems and reactor components using electromagnetic and acoustic fields. Furthermore, we pursue predictive modelling for future degradation based on measurement results.

As part of our comprehensive approach, when assessment results indicate the presence or absence of degradation, it is often necessary to perform destructive testing or disassembly for further validation. Therefore, our laboratory also focuses on statistical analysis methods to interpret measurement data and provide holistic evaluations of plant-wide integrity and reliability.

Amid countless unresolved issues, we continue our research with the aim of advancing knowledge and contributing, even in small ways, to the realization of a sustainable society.
