The paper describes the ANACAP analysis models and discusses the analysis comparisons with the test data. The analyses described in this paper were performed using ANACAP reinforced concrete models. NRC and JNES to study seismic issues important to the safe operation of commercial nuclear power plant (NPP) structures, systems and components (SSC). ![]() This paper describes a finite element analysis to predict the JNES/NUPEC cyclic and shaking table RC shear wall test data, as part of a collaborative agreement between the U.S. This task is challenging because of the large number of the ISFSI sites, variety of seismotectonic and site conditions, and effects that soil amplification, soil-structure interaction, and pad flexibility may have on the ground motions. The goal of the ground motion task is to develop the ground motions that would be representative of the range of seismotectonic and other conditions that any site in the Western US (WUS) or Central Eastern US (CEUS) might entail. The shake table surface represents the top of the concrete pad on which a dry storage system is placed. The major input into the shake table test are the seismic excitations or the earthquake ground motions – acceleration time histories in two horizontal and one vertical direction that will be applied to the shake table surface during the tests. These configurations cover 91% of the current dry storage configurations. Two dry storage configurations will be tested – horizontal and vertical above-ground concrete overpacks. The canister will be loaded with three surrogate fuel assemblies and twenty-nine dummy assemblies. The main component of the test unit will be the full-scale NUHOMS 32 PTH2 dry storage canister. This test will allow for quantifying the strains and accelerations on surrogate fuel assembly hardware and cladding during earthquakes of different magnitudes and frequency content. ![]() The more » Spent Fuel Waste Disposition (SFWD) program is planning to conduct a full-scale seismic shake table test to close the gap related to the seismic loads on the fuel assemblies in dry storage systems. When dry storage systems experience seismic loads, there are little data on the response of SNF assemblies contained within them. ![]() The dry storage systems are designed and licensed to withstand large seismic loads. During this time, the ISFSIs, and potentially consolidated storage facilities, will experience earthquakes of different magnitudes. Because a site for geologic repository for permanent disposal of SNF has not been constructed, the SNF will remain in dry storage significantly longer than planned. Currently, spent nuclear fuel (SNF) is stored in on-site independent spent-fuel storage installations (ISFSIs) at seventythree (73) nuclear power plants (NPPs) in the US.
