. t VIRGINIA ELECTRIC AND POWER COMPANY RICHMOND, VIRGINIA 23261 February 3, 1997 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.97-065 NL&OS/GDM Docket No.
50-280 50-281 License No. DPR-32 DPR-37 As a result of a Surry design change that replaced radiation monitoring recorders and ratemeters, modifications to two Emergency Response Data System (EADS) points were necessary.
These modifications were required to reflect changes in the instrument ranges for two common radiation monitor points. The changes are detailed in the Data Point Library (DPL) reference file forms in Attachment 1. Attachment 2 provides the revision summary (change report) for the affected points. The updated data base files, documented in Attachments 1 and 2, are also provided in the dBase IV
- format as Attachment 3.
Should you require additional information, please contact us.
Very truly yours, S. P. Sarver, Acting Manager Nuclear Licensing and Operations Support Attachments
