VIRGINIA ELECTRIC AND POWER COMPANY RICHMOND, VIRGINIA 23261 May 13~ 1994 United States Nuclear Regulatory Commission Attention: Document Control Desk Washington, D. C. 20555 Gentlemen:
VIRGINIA ELECTRIC AND POWER COMPANY NORTH ANNA POWER STATION UNITS 1 AND 2 SURRY POWER STATION UNITS 1 AND 2 EMERGENCY RESPONSE DATA SYSTEM DATA BASE UPDATES Serial No.
EE/TJK-CGL Docket Nos.
License Nos.94-296 RO 50-338 50-339 50-280 50-281 NPF-4 NPF-7
. DPR-32 DPR-37 As a result of a Surry Emergency Response Facility problem report, modifications to the point names of several Emergency Response Data System (EROS) points were necessary. It was discovered that incorrect system codes had been assigned to the containment sump level inputs. This correction, which affects one point per unit, was made at both Surry and North Anna. The changes are detailed in the Data Point Library (DPL) reference file forms contained in Attachments 1 and 2 for Surry Units 1 and 2 and North Anna Units 1 and 2, respectively. Attachments 3 and 4 provide revision summaries (change reports) for the affected points for Surry Units 1 and 2 and North Anna Units 1 and 2, respectively. The updated data base files are also provided in the dBase IV format on Attachment 5.
If you have questions regarding this information, please contact us.
Very truly yours, M. L. Bowling, Manager Nuclear Licensing & Programs Attachments:
