VIRGINIA ELECTRIC AND POWER COMPANY (DOMINION)
NORTH ANNA POWER STATION UNITS I AND 2 EMERGENCY RESPONSE DATA SYSTEM DATABASE UPDATES Modifications to four Emergency Response Data System (ERDS) points have been implemented at North Anna Power Station as a result of replacement of the process vent radiation monitors. The radiation monitors are common to both units. (The replacements were a result of a North Anna Design Change Package.) The changes are detailed in the Data Point Library (DPL) reference file forms provided in Attachments 1 and 2. Attachment 3 provides the revision summary (change report) for the affected points.
No new commitments are intended by this letter.
If you have any questions concerning these results, please contact us.
Very truly yours, S. P. Sarver Director - Nuclear Licensing and Operations Support Attachments
