Development of three-dimensional seismic isolation technology for next generation nuclear power plant applications

Takahashi, Kenji; Inoue, Kazuhiko; Ito, Kei; Fujita, Takafumi*

We carried out reflection seismic and multi-offset VSP surveys at JNC Shobasama-site to develop the investigation technique in the granite area, and evaluated the applicability of these geophysical methods.As the result of this study, we consider that a) It is possible to infer the existence of the lower angle fracture zone in the granite by reflection seismic survey and b) Multi-offset VSP supplements the result of reflection seismic survey and it is possible to infer the distribution of the fracture zone in deeper area in the granite.
