VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION UNITS I AND 2 WATER CHEMISTRY SURVEY Serial No.

87-461A SPS/GDM:pms Rl Docket Nos.

50-280 50-281 License Nos. DPR-32 DPR-37 As requested by your letter of July 21, 1987, we completed and forwarded a PWR Erosion-Corrosion Questionnaire in our letter dated September 18, 1987 (Serial No.87-461).

Part C of the questionnaire, Feedwater and Condensate Chemistry, was completed utilizing information for the condensate system unless the feedwater system was specifically identified.

In subsequent conservations with Jonas, Inc., an NRC contractor, we were requested to provide Part C information for the feedwater system.

Accordingly, feedwater data for the appropriate sections in Part C of the questionnaire are provided in the attachments.

If you have any further questions or require additional information, pl ease contact us.

Very truly yours, Attachment r--.;;~~c:--------
