Earthquake-associated events. Annual safety research report, JFY 2011

For the tsunami and slope stability as the earthquake-associated events that increased with the revision of the regulatory guide for reviewing seismic design of nuclear power reactor facilities, related technical standard and analysis code were leveled up to support the safety examination of the country. For tsunami study, the original plan was changed due to the 2011 Tohoku earthquake tsunami, analysis code of river run-up, sedimentation, probabilistic tsunami hazard and tsunami trace database were developed. For slope study, in addition to conventional stress criteria, in order to build a slope stability evaluation method, incorporating new indicators, such as deformation and strain, the following study was conducted. The large-scale shaking table test for E-defense, the test data were obtained. The applicability of slope stability analysis code was examined by using the shaking table test data. (author)
