TELEPHONE CONFERENCE CALL LIMERICK GENERATING STATION LICENSE RENEWAL APPLICATION LIST OF PARTICIPANTS February 9, 2011 PARTICIPANTS AFFILIATIONS Robert Kuntz Nuclear Regulatory Commission (NRC)
Juan Uribe NRC Sergiu Basturescu NRC Roy Mathew NRC Kerby Scales NRC Christopher Wilson Exelon Generation Company, LLC (Exelon)
Gene Kelly Exelon Deb Spamer Exelon Dave Clohecy Exelon Jim Jordan Exelon ENCLOSURE 1
ORAl 2.4.4-1 Clarify if there are any trash racks, basket strainers, traveling screens or any other debris preventionlremoving mechanisms that are part of the Circulating Water Pump House that would be required to be in scope of license renewal in accordance with 10 CFR 54.4. If so, also identify the applicable aging effects and the aging managing program (AMP) related to these components.
Discussion: The applicant clarified that the Circulating Water Pump House is in the flow path of the service water and that there is no intake structure and therefore there are no trash racks, basket strainers, traveling screens or any other debris prevention/removing mechanisms required. Therefore, the staff will not issue this draft RAI as a formal RAI.
ORAl 2.4.6-1 Confirm the inclusion of the "rubberized flat dumbbell-type water stops" that are located at all construction joints below the maximum expected groundwater level for all safety-related enclosures as stated in Limerick Generating Station (LGS) Updated Final Safety Analysis Report (UFSAR) Section 3.4.1.2 are within the scope of license renewal (LR) and subject to an Aging Management Review. Otherwise, justify the exclusion from the scope of the LR.
Discussion: The applicant indicated that the request is clear. This ORAl will be sent as a formal RAI.
ORAl 2.4.6-2 LGS UFSAR states in Section 2.4.2.3.3 that "measures are taken to limit the possible flow of flood water from the turbine enclosure into the control enclosure where the safety-related chilled water system is located at el 200'. These measures include controlling openings in the lower portion of the turbine enclosure walls, relying on flood control features within the turbine building, and by limiting the flow of water through the turbine enclosure doors by providing additional curbs and barriers inside the turbine enclosure and by administratively controlling the opening of certain doors."
However, LGS license renewal application (LRA) states in Section 2.4.6 that "not included in the boundary of the Control Enclosure is the adjacent tunnel located in the Turbine Enclosure which runs along the north, east and west sides of the Control Enclosure."
Provide additional information that clarifies the overall configuration and clearly states the boundary for LR between the Turbine Enclosure and the Control Enclosure. The additional information presented should have special emphasis on flood control and flood prevention measures/mechanisms between the two structures.
Discussion: The applicant clarified that the adjacent tunnel located in the Turbine Enclosure was included in the scope of license renewal but in a different system. Therefore, the staff will not issue this draft RAI as a formal RAJ.
ENCLOSURE 2
-2 ORAl 2.4.8-1 Confirm if the duplex-type basket strainers that are provided in each transfer pump discharge line that prevent solid particles or debris from entering the day tanks in the diesel oil storage tank structure would be required to be in scope of license renewal in accordance with 10 CFR 54.4. If so, also identify the applicable aging effects and the AMP related to this component. Otherwise, justify the exclusion from the scope of license renewal.
Discussion: The applicant confirmed that the strainers are in scope and are included as part of the piping, piping components, and piping elements components. Therefore, the staff will not issue this draft RAI as a formal RAI.
ORAl 2.4.8-2 Please provide additional information regarding the metal enclosure (butler building) that is located over the diesel oil storage tank structure. Specifically, the information should address and justify the exclusion of the metal enclosure from the scope of license renewal as well as a detailed description on how its failure would not prevent satisfactory accomplishment of a safety-related function per 10 CFR 54.4.

ORAl 2.4.16-1 LRA Section 2.4.16 states that blowout panels are provided at the turbine enclosure for pressure relief as well as internal flood relief purposes.
