  • G1000804 Development of an Evaluation Method for Seismic Isolation Systems of Nuclear Power Facilities Establishment of Crossover Piping Design Method

抄録

The crossover piping is installed between seismically isolated and non-isolated building; the reactor building (RB) is only isolated using seismic isolation systems whereas the turbine building (TB) is non-isolated. The crossover piping supported by both isolated and non-isolated building is deformed by large relative displacement between the two buildings. The flexible structure is required for crossover piping which allows the relative displacement. It also has to endure the seismic response of itself caused by different seismic excitations from both buildings. The seismic design for crossover piping needs evaluation considering both of the relative displacement and the seismic response. In this study, the results of shaking table tests of 1/10 scaled Main Steam (MS) piping model has been used to compare the seismic response analysis of crossover piping. Based on the results of shaking table tests and the analyses, the seismic design method for crossover piping is proposed.
