Review of Seismic Hazard Assessment for Radioactive Waste Disposal Facilities

Project Details


Seismic impact to radioactive waste disposal facilities may include strong ground-motion impact, fault displacement and ground deformation impact, and impact by secondary hazards. Estimation of strong ground-motion for a site commonly uses deterministic or probabilistic approach via a seismic hazard analysis which has been mature in methodology. Because a disposal site locates commonly in an underground cavern, ground-motions or secondary hazards by tsunami, landslide, liquefaction etc. are not controlling the design of the disposal facilities, and fault displacement and ground deformation become the control. Fault displacement and ground deformation occur generally at primary fault and its surrounding areas and these may have avoided in selecting the disposal site. Therefore, secondary faulting becomes the issue concerned. In the region close to the primary fault, there may exist secondary faults or shear zones. These weak zones may also move during movement of the primary fault affecting the safety of disposal facilities. This study intends to collect relevant information extensively, and to review seismic impact assessment methods for radioactive waste disposal facilities. Details of fault displacement hazard analysis, including development of method and actual applications, will be conducted in the following projects.
