FENOC FirstEnergyNuclear Operating Company James H. Lash 724-682-5234 Site Vice President Fax: 724-643-8069 March 28, 2007 L-07-053 ATTN: Document Control Desk U. S. Nuclear Regulatory Commission Washington, DC 20555-0001

Subject:

Beaver Valley Power Station, Unit Nos. 1 and 2 BV-1 Docket No. 50-334, License No. DPR-66 BV-2 Docket No. 50-412, License No. NPF-73 Emergency Response Data System In accordance with 10 CFR 50, Appendix E, Section VI, changes to the Beaver Valley Power Station (BVPS) Units No. 1 and No. 2 Data Point Libraries (DPL) for the Emergency Response Data System (ERDS) are provided in the Attachments.

Attachment 1 provides DPL pages for the data points that have been changed. Unit No. 1 DPL information associated with reactor vessel dynamic level high alarm limits was changed due to rescaling of the Reactor Vessel Level Indicating System dynamic head differential pressure levels. Changes for the Unit No. 2 DPL information associated with reactor coolant loop flow low alarm limits were implemented based on new defined operating limits. Attachment 2 provides a list of data points that have changed and a summary of the changes for each listed datapoint.

There are no regulatory commitments contained in this letter. If there are any questions or if additional information is required, please contact Mr. Henry L. Hegrat, Supervisor -

FENOC Fleet Licensing, at (330) 374-3114.
