Subject:

WPPSS HUCLEAR PROJECTS NOS.1 & 4 W?iP-1 EXCAVATION

Dear Mr. Boyd:

In response to PSAR Question 2.54, the Supply System co.mEtted to notify the Regulatory Staff when major excavations were completed and logs and maps of these excavations were available. The major excavation for the WNP-1 Containment and General Services Building (GSB) is now complete. The logs and maps of these excavations will be available by October 24, 1975.

The installation of the ground grid under the Containment and GSB J will begin about November 3 and the pouring of the Containment and GSB mud mats will begin about November 13, 1975. If the Staff desires l to view the exposed Ringold Formation, they will need to be at the I site before this time. The backfilling around the W:!P-1 Containment

, and GSB will not begin until mid-1976.

We expect the excavation for the WNP-1 spray pond to be completed by November 4,1975, and the logs and maps to be available about two weeks later.

Very truly yours, 8605290144 751022 b N PDR ADOCK 05000460 A PDR N. O.
