Masonry Block Walls
Dear Mr. Wagner:
Per your request, attached are typical response spectra curves used in the reanalysis of the Fort St. Vrain Masonry Block Walls.
These curves are for the various floor levels in the plant.
PSC reanalyzed the walls per I&E Bulletin 80-11 for the SSE event and used a damping value of 5%.
If you have further questions on the analysis details please contact Bob Gunnerson at (303) 571-8417.
Very truly yours, hw H. L. Brey, Manager Nuclear Engineering Division HLB / RAG:pa Attachment 8309200142 830906 PDR ADOCK 05000267 0
