Relief Request PR*05 Response to Request for Additional InformationRelief Request Page 1 Question:Request for Additional Information:
Does the test proposed in your submittal use a fixed system resistance to establish a repeatable reference condition and then measure, record, and evaluate pump differential pressure to assess pump performance trends?If so, then this approach does not appear to the NRC technical staff to be a deviation from the requirements of OM Code and, therefore, does not require relief.Please note that NRC regional inspection staff have previously reached a similar conclusion regarding testing of these pumps as documented in Inspection Report No.050000289/2004004, dated November 8, 2004 (ADAMS Accession No.ML043150481).
Also please note that, interpretation of ASME OM Code requirements is the purview of the ASME Committee on Operations and Maintenance and, if needed, their inquiry process is available for assistance in clarifying OM Code requirements." Response: Following additional review of the ASME OM Code and the conclusions in Inspection Report No.0500028912004004, Exelon Generation Company, LLC (Exelon)agrees that the proposed testing of Reactor Building Emergency Cooling River Water Pumps AlB meets the intent of the ASME OM Code for a Group B pump test and adequately monitors pump performance and therefore this relief request is not needed.The test condition is at a substantial, repeatable flow at the"readily duplicated" reference point.Pump performance is then evaluated between comprehensive pump tests by the trends of differential pressure.In view of this information, Exelon hereby withdraws this relief request.
