This report presents engineering application guidelines for conducting seismic soil-structure interaction (SSI) analyses of nuclear power plant structures. These guidelines are largely based on the results obtained and lessons learned from the Large-Scale Seismic Test (LSST) program involving {1/4} and 1/12 scaled containment models in Lotung, Taiwan. The development of these guidelines has taken into consideration the guidelines recommended in the ASCE Standard 4--86, Seismic Analysis of Safety-Related Nuclear Structures'', and the new revision (Revision 2) of the NRC Standard Review Plan (SRP), Section 3.7.2, Seismic System Analysis.'' The guidelines presented in this report follow an approach which reckons every necessary step for characterizing and providing an adequate solution to the total SSI problem which is broken down into a series of five SSI subproblems, namely, site response problem, foundation scattering problem, structural modelling problem, foundation impedance problem, and interaction response solution problem. The four analysis methods evaluated are the lumped-parameter (soil-spring) method, the continuum-halfspace substructing (CLASSI) method, the discretized-halfspace substructing (SASSI) method, and the finite element direct (FLUSH and ALUSH) method. The approach used herein was found to be very effective for evaluating the validities of the various SSI analysis results and findings of the LSST program. The guidelines presented herein place emphasis on the general requirements, procedures, and criteria for conducting SSI analyses in an industry environment by those involved in the seismic design or performance evaluation of nuclear power plant structures and equipment. 53 refs., 17 figs.
