Subject:
Beaver Valley Power Station, Unit No. 2 BV-2 Docket No. 50-412, License No. NPF-73 Emergency Response Data System In accordance with 10 CFR 50, Appendix E, Section VI, revisions to the Beaver Valley Power Station (BVPS) Unit No. 2 Data Point Library (DPL) for the Emergency Response Data System (ERDS) are enclosed. The DPL changes are associated with the increasing of the high alarm setpoints of the Intermediate Range Detectors (Point IDs N0035A and N0036A). The Attachment provides a summary of the changes made for these data points.
There are no regulatory commitments contained in this letter. If there are any questions or if additional information is required, please contact Mr. Thomas A. Lentz, Manager-FENOC Fleet Licensing, at 330-761-6071.
