ME7532) Dear Mr. Pacilio: By letter dated October 28, 2011 (Agencywide Documents Access and Management System Accession No. ML 113010335), Exelon Generation Company, LLC (Exelon, the licensee) submitted a relief request proposing to perform an alternative testing method for the Reactor Building Emergency Cooling River Water Pumps at Three Mile Island Nuclear Station, Unit 1. The Nuclear Regulatory Commission staff has been reviewing the submittal and, based on the information provided, it appears that relief from the requirements of the American SOCiety of Mechanical Engineers Operation and Maintenance Code is not required. Therefore, please review the enclosed request for additional information (RAJ) and provide an appropriate response. The question was sent via electronic transmission on March 26, 2012, to Mr. Thomas Loomis, of your staff. The draft question was sent to ensure that it was understandable, the regulatory basis was clear, and to determine if the information was previously docketed. The issues relating to the draft question were discussed in teleconferences with your staff on March 5, 2012, and on March 21, 2012. It was agreed with Mr. Loomis that a response to this RAI would be submitted by April 30, 2012. Please contact me at 301-415-2833, if you have any questions.

The relief request is associated with the fourth Inservice Testing interval at TMI-1, and it proposes alternative testing of the Reactor Building Emergency Cooling River Water Pumps. The U.S. Nuclear Regulatory Commission (NRC) staff has been reviewing the submittal and, based on the information provided, it appears that relief from the requirements of the American Society of Mechanical Engineers (ASME) Operation and Maintenance Code (OM Code) is not required. Therefore, please review the following request for additional information and provide an appropriate response. PR-05 -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. IVIL043150481). 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.

ME7532)
Dear Mr. Pacilio:
By letter dated October 28, 2011 (Agencywide Documents Access and Management System Accession No. ML113010335), Exelon Generation Company, LLC (Exelon, the licensee) submitted a relief request proposing to perform an alternative testing method for the Reactor Building Emergency Cooling River Water Pumps at Three Mile Island Nuclear Station, Unit 1.
The Nuclear Regulatory Commission staff has been reviewing the submittal and, based on the information provided, it appears that relief from the requirements of the American SOCiety of Mechanical Engineers Operation and Maintenance Code is not required. Therefore, please review the enclosed request for additional information (RAJ) and provide an appropriate response. The question was sent via electronic transmission on March 26, 2012, to Mr. Thomas Loomis, of your staff. The draft question was sent to ensure that it was understandable, the regulatory basis was clear, and to determine if the information was previously docketed. The issues relating to the draft question were discussed in teleconferences with your staff on March 5, 2012, and on March 21, 2012. It was agreed with Mr. Loomis that a response to this RAI would be submitted by April 30, 2012.
Please contact me at 301-415-2833, if you have any questions.

REQUEST FOR ADDITIONAL INFORMATION THREE MILE ISLAND NUCLEAR STATION, UNIT 1 RELIEF REQUEST ASSOCIATED WITH THE FOURTH INSERVICE TESTING INTERVAL RELIEF REQUEST PR-05 DOCKET NO. 50-289 By letter dated October 28, 2011 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML113010335), Exelon Generation Company, LLC submitted a relief request for Three Mile Island Nuclear Station, Unit 1 (TMI-1). The relief request is associated with the fourth Inservice Testing interval at TMI-1, and it proposes alternative testing of the Reactor Building Emergency Cooling River Water Pumps. The U.S. Nuclear Regulatory Commission (NRC) staff has been reviewing the submittal and, based on the information provided, it appears that relief from the requirements of the American Society of Mechanical Engineers (ASME) Operation and Maintenance Code (OM Code) is not required. Therefore, please review the following request for additional information and provide an appropriate response.
PR 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. IVIL043150481). 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.
