NL&P/CGL Docket Nos.

License Nos.92-492 RO 50-280 50-281 DPR-32 DPR-37 Modifications were recently made to two Emergency Response Data System (EADS) points for total high head safety injection cold leg flow for Surry Units 1 and 2. The changes, which were made to resolve recent Emergency Response Facility problem reports, are detailed in the Data Point Library (DPL) reference file sheets contained in. Attachment 2 provides revision summaries (change reports) for the affected points. The updated data base files, documented in Attachments 1 and 2, are also provided in the dBase IV format on Attachment 3.

If you have questions regarding this information, please contact us.

Very truly yours,
