Research Overview

This project aims to realize a safe and secure society through risk recognition and analysis, development of risk reduction technologies, and management and communication of risks, based on innovative technological developments promoted by this research group. Specifically, in collaboration with companies and government agencies, we are promoting several projects related to the compatibility of structural materials and operating environments, and several projects related to the development and implementation of technologies for lowering the risks of severe accidents.

Research Features

In response to the growing social demand for development of technologies that achieve carbon neutrality, we proactively work on the development of green technologies. We address material technology related to ammonia combustion power generation, which minimizes carbon dioxide emissions, and material risk issues in restarting and extending the service period of nuclear power generation facilities to ensure a stable supply of energy. We also support the development and commercialization of equipment to prevent the spread of radioactive waste disposal as an indispensable long-term back-end technology, as well as equipment to control environmental pollution in the event of accidents. In addition, with regard to the time-related degradation of underground infrastructure, bridges, roads, and other social infrastructures, which has recently become a pressing issue, we work with small and medium-sized enterprises (SMEs) that are responsible for the practical aspects of issues to develop a technological foundation for reliable maintenance and proprietary technologies for risk reduction.

Expected Outcomes and Developments

1. We are elucidating and evaluating material damage mechanisms that occur in power generation facilities as a result of the development of new ammonia combustion technologies for carbon neutrality, and apply countermeasure technologies based on assessments of ammonia combustion power generation facilities to achieve long-term stable operation.
2. We are designing power generation facilities with high structural soundness, safety, and economic efficiency by upgrading material risk assessment and countermeasure technologies for restarting and extending the service life of nuclear power generation facilities and for aging thermal power generation facilities in order to ensure long-term stable energy supply in the carbon-neutral era.
3. We are developing evaluation methods for the ultra-long-term durability of metal overpacks for the disposal of high-level radioactive waste, which is inevitable for the operation of nuclear reactors and the utilization of nuclear energy.
4. We are promoting the development and deployment of advanced technologies designed to contain the impact of severe accidents or equipment failures, and to minimize environmental pollution.
5. We are supporting the development and implementation of innovative proprietary technologies by small and medium-sized enterprises (SMEs) to reduce the risk of age-related deterioration of underground infrastructure, bridges, roads, and other social infrastructures.
6. Through on-the-job training, we are promoting the development of human resources who possess both broad knowledge and deep expertise necessary to solve problems.
