SUBJECT:

Waterford 3 SES Docket No. 50-382 IE Bulletin 79-02 Revision 1

REFERENCES:

(1) Telecon of November 20, 1979 between Mr. Stewart, Region IV, NRC, and Mr. A. Jones, LP&L (2) Letter LPL 11505 dated July 9, 1979

Dear Mr. Seyfrit:

In response to the referenced telecen we have found that reference (2) adequately discussed the subject revision with the exception of item 4-b, for which this amplification is provided.

We would like to further address the OA documentation requirements for proper bolt instal ~ation. As we have addressed before, the QC documentation for each base plate has included the number of anchor bolts, bolt size, embedment length, and torgue magnitude applied. In addition, plate bolt hole size, bolt spacing and edge distance to the side of a concrete member are specified on a design drawing. Any deviations from the drawings which are found at the time of installation are fully documented. All deviations are reviewed and evaluated by the design engineer.

As it was mentioned in the previous response, this project has used only wedge type concrete expansion anchor bolts. Therefore, the bolt parameters - thread engagement, and full expansion of the shell are not discussed.

We trust this has clarified the further concerns of the reviss! bulletin. If you have any questions, please advise.
