VIRGINIA ELECTRIC AND PowER COMPANY RICHMOND, VIRGINIA 23261 January 23, 1998 United States Nuclear Regulatory Commission Attention: Document Control Desk Washington, D.C. 20555 Gentlemen:

VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION UNITS 1 AND 2 EMERGENCY RESPONSE DATA SYSTEM DATABASE UPDATES Serial No.98-046 NL&OS/GDM Docket No.

50-280 50-281 License No. DPR-32 DPR-37 As a result of the final implementation phase of the Surry design change that replaced radiation monitoring recorders and ratemeters, modifications to two additional Emergency Response Data System (EROS) points were necessary.

These modifications were required to reflect changes in the instrument ranges for two radiation monitoring points common to both units. The changes are detailed in the Data Point Library (DPL) reference file forms provided in Attachment 1. Attachment 2 provides the revision summary (change report) for the affected points.

Should you require additional information, please contact us.

Very truly yours,
