Houston. Texas 77001 SFN: V-0100 Mr. Domenic B. Vassallo, Acting Director Division of Project Management U. S. Nuclear Regulatory Commission 1717 H. Street Washington, D. C. 20555
Dear Mr. Vassallo:
South Texas Project Units 1 & 2 Docket Nos. STN 50-498, STN 50-499 Clarification of Summary of Meeting to Discuss Soil / Structure Interaction Analysis A meeting was held on September 18, 1979, with the NRC at Bethesda, Maryland, to discuss soil / structure interaction analysis for the South Texas Project.
Subsequently, the Nuclear Regulatory Commission issued a meeting summary dated October 11, 1979, which stated in the second sentence of the second paragraph:
"We [NRC] agreed that the elastic half-space model was an accept-able approach."
As was explicitly stated by HL&P at the outset of the meeting on September 18, HL&P does not agree that the elastic half-space model is an acceptable approach.
The elastic half-space coalysis is being performed only to provide a response to NRC question 130.12. Once again, it is the position of Houston Lighting and Power Company that the finite element model is the correct procedure to be used for this analysis. The derived spectra which were included in the South Texas Project Preliminary Safety Analysis Report adequately model the maximum expected seismic motion.
Very truly yours, E. A. Turner Vice President Power Plant Construction
