965 Chesterbrook Boulevard A Unit of PECO Energy. Wayne. PA 19087-5091 May 10,1999 Docket Nos. 50-277 50-278 License Nos. DPR-44 DPR-56 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555

SUBJECT:

Peach Bottom Atomic Power Station, Units 2 and 3 Emergency Response Data System Data Point Library Changes

Dear Sir:

The purpose of this letter is to update some of the transmitted data points provided in the Data Point Library for the Emergency Response Data System (ERDS) for Peach Bottom Atomic Power Station (PBAPS), Units 2 and 3. ERDS is a direct, near real-time, electronic data link between PBAPS and the NRC's Operations Center which provides for the automated transmission of a limited data set of selected parameters.

10CFR50, Appendix E, Section VI.3.a requires that any changes in computer hardware or software that affect the transmitted data points identified in the ERDS Data Point Library must be submitted to the NRC within 30 days after the changes are completed. NUREG-1394, Revision 1, " Emergency Response Data System (ERDS) Implementation," provides the appropriate guidance for submitting ERDS data point library information.

Accordingly, the enclosed ERDS data point information for PBAPS is being submitted within 30 days after the changes have been completed as required by 10CFR50, Appendix E. The data point information is a format consistent with the guidance specified in NUREG-1394. In addition, the changes have been annotated with a vertical line in the margin adjacent to the change to the data point library.

If you have any questions or require additional information, please do not hesitate to contact us.

Very truly yours, I
