Exelon Generation Company, LLC wwwexeloncorp corn Nuclear LaSalle County Station 2601 North 21" Road Marseilles, IL 61341-9757 October 11,2002 10 CFR Appendix E United States Nuclear Regulatory Commission Attention: Document Control Desk Washington, D.C. 20555 LaSalle County Station, Units 1 and 2 Facility Operating License Nos. NPF-1 1 and NPF-1 8 NRC Docket Nos. 50-373 and 50-374

Subject:

Notification of Pending Changes to the Emergency Response Data System In accordance with Subsection 3.b of 10 CFR 50 Appendix E Section VI, "Emergency Response Data System," Exelon Generation Company, LLC (EGC) is providing notification of pending changes to the Emergency Response Data System (ERDS) that could potentially affect ERDS transmission format or computer protocol. Currently, the ERDS program transmits data collected and formatted by the Point History program with data retrieved from the station process computer. A new process computer is scheduled to be installed in LaSalle County Station Unit 2 during the upcoming refueling outage scheduled for January 21, 2003. The new process computer does not support the existing Point History program.

Therefore, to support this modification, a revised ERDS interface program is being developed that will collect and format data from another program which receives data from the process computer, the ProcessBook (PI) data historian. The new Unit 2 process computer will send its data to the PI data historian for subsequent transmission via ERDS. None of the existing data points transmitted by ERDS will be modified. Additionally, there is no intention of changing transmission format or computer protocol. This condition, however, cannot be verified until testing of the new interface program is completed. The interface program will be initially tested in a computer lab with subsequent live transmission testing to follow. EGC personnel will be contacting NRC Operations Center computer personnel to arrange for this testing once the computer lab testing has been completed.
