VIRGINIA ELECTRIC ' AND POWER COMPANY NORTH ANNA POWER STATION UNITS 1 AND 2 EMERGENCY RESPONSE DATA SYSTEM DATA BASE UPDATES As a result of a North Anna Emergency Response Facility problem report, modification to an Emergency Response Data System (ERDS) point was necessary.
The description of a single radiation monitoring point, which is common to both units, was updated. No other parameters for this point were modified. The change is detailed in the Data Point Library (DPL) reference file forms for North Anna Units 1 and 2 contained in Attachment 1. provides revision summaries (change reports) for the affected point for North Anna Units 1 and 2. The updated data base files, documented in Attachments 1 and 2, are also provided in the dBase IV format on.
If you have questions, please contact us.
Very truly yours,
