The geosphere science sector conducts research and development related to the evaluation of the foundation ground and deep underground environment for structures including electric power facilities through activities such as geological survey, active fault survey, geophysical exploration, rock survey and testing, and groundwater survey. They are aimed at the siting evaluation, construction and maintenance of the structures.
The earthquake engineering sector conducts research on seismic and ground motion evaluation and earthquake hazard evaluation covering the occurrence to propagation of earthquakes, and research on seismic performance evaluation and seismic fragility evaluation for the ground and structures. In addition, the sector conducts research intended to contribute to mitigation of earthquake disasters and effective maintenance, for electric power facilities, through disaster risk evaluation and risk control technologies according to the target structure.
Natural external forces due to earthquake, wind, snow fall, and regional corrosive environment causes multiple negative impact to electric power systems. Therefore, the structural engineering sector conducts research and surveys associated with natural disaster mitigation technologies, maintenance and structural design improvement issues for electric power structure and equipment based on the forefront technologies including mechanics, material science, and IoT technologies.
The fluid dynamics sector conducts research on the prediction of the influence of natural disasters such as rainfall, wind and snow, and tsunami on electric power facilities, and measures against such influence, with the aim of contributing to the development and improvement of fluid-related technology at electric power facilities. In addition, the sector works on the resolution of problems related to multi-physics and multi-scale phenomena, such as heat, phase change, earth and sand, fluid and structures, and so on, by developing numerical analysis technology, observation technology and experiment technology.
The Nuclear Fuel Cycle Backend Research Center conducts research on technology of low-level and high-level radioactive waste disposal, and technology for transporting and storing spent fuels from nuclear power plants. The center also conducts research on fire protection technology for nuclear power plants.
