VIRGINIA ELECTRIC AND POWER COMPANY RICHMOND, VIRGINIA 23261 March 9, 1999 United States Nuclear Regulatory Commission Serial No.: 99-147 Attention: Document Control Desk NLOS/MM RO Washington, D.C. ~0555-0001 Docket Nos.: 50-280/281 License Nos.: DPR-32/37 Gentlemen:
VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION UNITS 1 AND 2 EMERGENCY RESPONSE DATA SYSTEM DATABASE UPDATES Modifications to
- six Emergency Response Data System . (EROS) points have been implemented at Surry Power Station to reflect changes in the descriptions for six auxiliary feedwater flow points that were modified to indicate their RG 1.97 status. Additionally, the liquid waste radiation monitoring point R3RM209C was deleted from the EROS database>
(This radiation monitor was removed from service under a Surry Design Change Package:)
- The changes are detailed in the Data Point Library (DPL) reference file forms provided in I/
II
, I . Attachment 2 provides the revision summary (change report) *for the affected points.
No new commitments are intended by this letter. If you have any questions concerning .1/-v2~
these results, please contact us.
