Dear Mr. Miller:
4 9
W Clinton Power Station Unit 1 Docket No. 50-461 In the course of developing responses to NRC's request for information on seismic soil-structure interaction analysis, including soil properties variation, a review of the dynamic soil properties was undertaken.
The goal of the review was to define the upper and lower bound curves of soil shear modulus values.
At the same time it was decided to develop site specific response spectra for Clinton site.
For this purpose an estimate of shear wave velocities for soils present below the foundation mat was required.
A review of the shear wave velocities given in FSAR figures 2.5-369 thru 2.5-371 suggested that in light of the knowledge gained from recent geophysical tests conducted at various sites of comparable soil deposits, the shear wave velocities given in these figures were too high.
The shear wave velocities given in the FSAR were computed from the measured compressional wave velocities and estimated Poisson's ratio.
In view of the current knowledge the estimated values of Poisson's ratio are considered too low.
Based on the above, a thorough review of the shear wave velocities and the low-strain soil moduli, was started by Dames & Moore.
In order not to delay the work on site-specific response spectra, an estimated value of 2500 ft/sec for the Illinoian till layer and 1000 ft/sec for the structural fill layer was given to Weston Geophysical, with the understanding that for the Illinoian till layer the velocity could range between 2000-2500 ft/sec and a variation in this range will not have any significant impact on the site specific response spectra.
E201050231 011231 hE PDR ADOCK 05000461 gI A
Mr. James R. Miller U-0348 Dames & Moore has completed its review of the shear wave velocities and the low strain soil moduli values.
Re-sults of this review are documented in the attached revised FSAR figures 2.5-369 thru 2.5-371, and tables 2.5-46 and 2.5-48.
We have evaluated the effect of the above changes on the plant design and determined that there is no impact on the design.
We believe that these changes have only a conservative effect on the site specific response spectra, if any.
Weston Geophysical has been informed of the latest revision in the shear wave velocity of the Illinoian till layer (from 2500 ft/sec to 2100 ft/sec) and they are proceeding to incorporate the effect of this, if any, in their work of site specific response spectra development.
The revised FSAR tables and figures included here will be docketed in the next amendment of the FSAR.
Sincerely,
