- VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION UNITS 1 AND 2 EMERGENCY RESPONSE DATA SYSTEM DATABASE UPDATES Serial No.97-275 NL&OS/MAE
. Docket No.
50-280 50-281 License No. DPR-32 DPR-37 In accordance. with 10 CFR 50 Appendix E, Section Vl.3.a, we are. submitting modifications to five Emergency Response Data System (EROS) points which were
. necessary as a result of a Surry design change. The instrument ranges for five Unit 1 radiation monitor points were modified. 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.
Should you require additional information, please contact us.
Very truly yours,
