Impact of new K Area geotechnical parameters on K Reactor restart response spectra. Seismic Structural Engineering

摘要

This report provides a description of a study performed to evaluate the impact of recently obtained soils parameters on the 105-K Reactor using Soil-Structure Interaction (SSI) analysis. This study includes: the frequency check of the reactor building based on the fixed base analysis; the modification of the computer model to reflect actual building properties and building frequencies; The live load impact on seismic analysis; The comparison of soil spectrum at elev. (minus)50 ft with 60% of RG1.60 curve; comparison of spectral results to the previous FREDA and SASSI results; and implications to the stack building analysis.
