Subject:
Catawba Nuclear Station Docket Nos. 50-413 ar.d 50-414 Direct Generation Response Spectra Gentlemen:
A meeting was held on July 19, 1988 in the NRC's offices to discuss our snubber reduction program and the application of Direct Generation Response Spectra (DGRS). As a result of the meeting, the NRC asked that a comparison among the results from the direct generation method, time history method, and actual earthquake records. The Perry containment should be considered as a representative structure for which the necessary seistic data are available for performing the comparison. Attached is our response to this action item.
Very truly yours, W jffe f

'e Action item:
A comparison will be made of results from the direct generation method, time history method and actual earthquake records. The Perry containment will be considered as a representative structure if the necessary recorded seismic even' results for the comparison are available.
Response
Information was received on the Perry containment stick model from Gilbert /Comonwealth, Inc. and the base mat recorded time histories from Stevensen & Associates. This information was used to perform an analysis similar to the one performed in Appendix A, paragraph A.2.1 of Reference i
1.
In that section, Gilbert /Comonwealth compared their analytical response spectra at elevation 688'+ 6" of the Perry containment stick model with the recorded response spectra at elevation 686'.
Figures A.1 through A.6 (copies attached) show the re3ults.
The Perry containment model (natural frequencies, mode shapes, & nodal masses) was entered into EDASP and the base mat time histories were applied to the model.
Response spectra in each direction were computed at the base of the model and at elevation 686'+6" of the containment using time history analysis.
The results of this and the Gilbert time history analysis were compared as a baseline check of the input time history and containment model. Figures 1 through 3 show the base mat response spectra along with the. elevated (elevation 688'+ 6") spectra computed by Gilbert /Comonwealth (from Figures A.4, A.5, & A.6) and the elevated spectra computed by Duke Power using time history analysis. The base mat spectra compared well with the recorded base spectea show) in Figures A.1, A.2, & A.3.
The elevated response spectra also compared well, showing similar frequency content and only slightly different peak responses.
These comparisons showed that we were using the same base time histories and containment model as Gilbort.
Base Power Spectral Densities were computed from the base response spectra shown in Figures 1 through 3.
The PSD's were then applied to the containment model and response spectra were computed at elevation 666'+
6".
Figures 4 through 6 show plots of the elevated recorded response spectra (from Figures A.1, A.2, & A.3), the Gilbert /Comonwealth time history generated response spectra (from Figures A.4, A.5, & A.6), and the Duke Power PSD generated response spectra.
These figures show that the PSD generated results compare at least as well as the time nistory results to the recorded spectra. Thit is in agreement with our previous
(
submittals which showed that the PSD technique compared favorably with time histor y tect.niques.
