U.S. Nuclear Regulatory Commission Integrated Plan Report to EA-13-109 June 30, 2015 Page 2 On June 6, 2013, the Nuclear Regulatory Commission ("NRC" or "Commission") issued an order (Reference 1) to Exelon Generation Company, LLC (EGC). Reference 1 was immediately effective and directs EGC to require their BWRs with Mark I and Mark II containments to take certain actions to ensure that these facilities have a hardened containment vent system (HCVS) to remove decay heat from the containment, and maintain control of containment pressure within acceptable limits following events that result in loss of active containment heat removal capability while maintaining the capability to operate under severe accident (SA) conditions resulting from an Extended Loss of AC Power (ELAP). Specific requirements are outlined in of Reference 1.
Reference 1 required submission of a Phase 1 Overall Integrated Plan pursuant to Section IV, Condition D by June 30, 2014. Reference 2 endorses industry guidance document NEI 13-02, Revision 1 (Reference 3) with clarifications and exceptions identified in Reference 2. Reference 4 provided the EGC initial answer to the Order regarding reliable hardened containment vents capable of operation under severe accident conditions. Reference 5 provided the Limerick Generating Station, Units 1 and 2 Phase 1 Overall Integrated Plan.
Reference 1 requires submission of a status report at six-month intervals following submittal of the Phase 1 overall integrated plan. Reference 3 provides direction regarding the content of the status reports. Reference 6 provided the first six-month status report pursuant to Section IV, Condition D.3 of Reference 1 for Limerick Station. The purpose of this letter is to provide the second six-month status report for Phase 1 pursuant to Section IV, Condition D.3, of Reference 1, that delineates progress made in implementing the requirements of Reference 1.
The enclosed report provides an update of milestone accomplishments since the last status report, including any changes to the compliance method, schedule, or need for relief and the basis, if any. The enclosed report also addresses the NRC Interim Staff Evaluation open items contained in Reference 7.
This letter contains no new regulatory commitments. If you have any questions regarding this report, please contact David P. Helker at 610-765-5525.
I declare under penalty of perjury that the foregoing is true and correct. Executed on the 301h day of June 2015.
Respectfully submitted, c~ ~

Enclosure Limerick Generating Station, Units 1 and 2 Second Six Month Status Report for Phase 1 Implementation of Order EA-13-109, "Order Modifying Licenses with Regard to Reliable Hardened Containment Vents Capable of Operation Under Severe Accident Conditions" 1 Introduction Limerick Generating Station, Units 1 and 2 developed an Overall Integrated Plan (Reference 1 in Section 8), documenting the installation of a Hardened Containment Vent System (HCVS) that provides a reliable hardened venting capability for pre-core damage and under severe accident conditions, including those involving a breach of the reactor vessel by molten core debris, in response to Reference 2. This enclosure provides an update of milestone accomplishments since submittal of the Phase 1 First Six Month Status Report, including any changes to the compliance method, schedule, or need for relief/relaxation and the basis, if any.
2 Milestone Accomplishments The following milestones have been completed since December 01, 2014, and are current as of June 01, 2015.
- Second Six-Month Update (complete with this submittal) 3 Milestone Schedule Status The following provides an update to Part 5 included in the Overall Integrated Plan (OIP). It provides the activity status of each item, and whether the expected completion date has changed. The dates are planning dates subject to change as design and implementation details are developed.
The revised milestone schedule does not impact the order implementation date.
Note: Phase 2 implementation milestones for Limerick will be provided with the December 2015 OIP submittal.

- Limerick Generating Station HCVS Design has decided to replace all references to a Secondary Containment Isolation Valve (SCIV) with a rupture disc for a pressure sufficient to withstand leakage through the downstream Primary Containment Isolation Valve (PCIV) during a Design Basis Accident or testing.
- A purge system has been chosen as the method to prevent hydrogen deflagration. The purge system will be used to rupture the disc to allow anticipatory venting.
5 Need for Relief/Relaxation and Basis for the Relief/Relaxation Limerick Generating Station expects to comply with the order implementation date; therefore, no relief/relaxation is required at this time.
