The proposed amendment would an increase in the maximum power level from 3514 megawatts thermal (MWt) to 3951 The requested change, referred to as an extended power uprate, represents an increase approximately 12.4 percent above the current licensed thermal power The Nuclear Regulatory Commission (NRC) staff is reviewing your submittal and determined that additional information is needed to complete its review. The specific are found in the enclosed request for additional information (RAI). The RAI questions provided in draft form to Mr. Kevin Borton of your staff via e-mails on August 6, 2013, August 26, 2013. The draft questions were sent to ensure that the questions understandable, the regulatory basis for the questions was clear, and to determine if information was previously A conference call between the NRC staff and the Exelon staff was held on September 17, to discuss the questions.

The requested change, referred to as an power uprate (EPU), represents an increase of approximately 12.4 percent above the licensed thermal power The Nuclear Regulatory Commission (NRC) staff is reviewing your submittal and determined that additional information is needed to complete its review. The specific request additional information (RAI) is addressed Reactor Systems Branch (SRXB) Reviewer:
Ben Parks SRXB RAI-29 With regard to the overpressure analyses performed in support of the requested EPU, provide the number of safety relief valves (SRVs) and safety valves (SVs) assumed available, including setpoints and assumed lift setpoint tolerances.
Confirm whether the EPU safety analyses bound conditions associated with the proposed SRV and SV lift setpoint tolerance increases that were requested by Exelon's license amendment request for PBAPS, Units 2 and 3, dated June 10,2013 (ADAMS Accession No. ML131750144).
SRXB RAI-30 Attachment 9 to the application dated September 28, 2012, describes proposed modifications to PBAPS associated with the EPU. Condensate storage tank (CST) modifications are described in Enclosure ge to Attachment
- 9. Section 3.1 of Enclosure ge describes the addition of a CST standpipe to "ensure a CST dedicated usable volume for the HPCI [high pressure coolant injection]
and RCIC [reactor core isolation cooling] pumps for SBO [station blackout], A TWS [anticipated transient without scram1, and Appendix R events." This section refers to Enclosure
-Section 2.3.5, "Station Blackout," of the Power Uprate Safety Analysis Report (PUSAR1) and states that "[t]he CST volume needed for SBO at EPU conditions is approximately 94,570 gallons." Provide the EPU SBO analysis that concludes that this is the CST inventory required for mitigation.
Electrical Engineering Branch (EEEB)
Reviewer:
Swagata Som EEEB RAI-16 On page 2-135 in Section 2.3.5 of the PUSAR, the licensee states that "[e]valuation of the PBAPS Class 1 E Battery Capacity has shown that PBAPS has adequate battery capacity to support decay heat removal during a SBO for the required coping duration." Page 2-134 of the PUSAR indicates that SBO was re-evaluated for the proposed EPU using the guidelines of NUMARC 87-00, "Guidelines and Technical Bases for NUMARC Initiatives Addressing Station Blackout at Light Water Reactors" and NRC Regulatory Guide (RG) 1.155, "Station Blackout." Explain the design duty cycle of Class 1 E battery to support all SBO loads for the required SBO coping duration.
Confirm that the PBAPS Class 1 E batteries and alternate alternating current sources will have adequate capacity and capability during the plant power uprated condition to support SBO loads for the entire SBO coping duration consistent with RG 1.155 and NUMARC 87-00. Health Physics and Human Performance Branch (AHPB) Reviewer:
Molly Keefe AHPB RAI-6 On pages 2 and 3 of Attachment 3 to the supplement dated May 24, 2013, the licensee described changes to current operator actions related to emergency or abnormal operating procedures that will occur as a result of the proposed EPU. Specify what controls are in place to assure the following: Cues exist that alerts the operator to action in a timely manner. Tasks are within the capability of all PBAPS operators. Operator feedback capability exists to determine whether the actions are complete and effective. Training content, method, and frequency are determined and implemented. The location and accessibility of required displays and controls are considered. 1 A proprietary (i.e., non-publicly available) version of the PUSAR is contained in Attachment 6 to the application dated September 28,2012. A non-proprietary (i.e" publicly available) version of the PUSAR is contained in Attachment 4 to the application dated September 28, 2012.
-3 List the controlled procedures that guide the operator's actions for the cited changes to operator actions. AHPB RAI-7 Given the number of new operator actions, please discuss how the impacts of the EPU and associated plant modifications were identified and what, if any, analysis was done to understand impacts to operator workload.
