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. ERf.9 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 Deen 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 reference indicating whether the point is an addition, [/

replacement, or change to the data point library.

Very truly yours, -
