Follow-Up Response to Request Dated June 24, 1993 30 Percent Steam Generator Tube Plugging Analysis This letter provides additional information in response to your request for information dated June 24, 1993, concerning Duquesne Light Company's (DLC) 30 percent tube plugging analysis. By letter dated July 13, 1993, we provided a partial response to your request and submitted a copy of the 10 CFR 50.59 safety evaluation based on WCAP-13707 "30% Steam Generator Tube Plugging Analysis Program Final Engineering and Licensing Report." We also committed to provide both proprietary and non-proprietary versions of both the initial issue and Revision 1 of WCAP-13707. Attachment A provides items which partially satisfy the above commitment by including WCAP-13707 proprietary and WCAP-13811 non-proprietary versions along with a copy of the associated proprietary information notice, copyright notice and affidavit. Revision 1 of WCAP-13707 is not yet complete; however, it is expected to be completed and submitted within 60 days.

WCAP-13707 contains information which is proprietary to Westinghouse Electric Corporation. Accordingly, we request that this information be withheld from public disclosure in accordance with 10 CFR 2.790.

If you have any questions regarding the attached response, please contact Mr. Steve Sovick at (412) 393-5211.

Sincerely, J.
