VIRGINIA ELECTRIC AND POWER COMPANY RICHMOND, VIRGINIA 23261 April 12, 1994 United States Nuclear Regulatory Commission Attention: Document Control Desk Washington, D. C. 20555 Gentlemen:
VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION UNIT 1 EMERGENCY RESPONSE DATA SYSTEM DATA BASE UPDATES Serial No.
NL&P/CGL Docket Nos.
License Nos.94-195 RO 50-280 DPR-32 Modifications were recently made to the instrument range for the auxiliary feedwater flow points for Surry Unit 1. As part of the outage-related design change package -
associated with the Control Room Design Review modifications, the auxiliary feedwater flow range has been expanded from O - 350 gpm to O - 400 gpm. The changes are detailed in the Data Point Library (DPL) reference file forms contained in. Attachment 2 provides revision summaries (change reports) for the affected points for Surry Unit 1. The updated data base files are also provided in the dBase IV format on Attachment 3.
If you have questions regarding this information, please contact us.
Very truly yours, M. L. Bowling, Manager Nuclear Licensing & Programs Attachments:
