SUBJECT:

MID-CYCLE PERFORMANCE REVIEW AND INSPECTION PLAN -

LIMERICK GENERATING STATION (REPORT 05000352/2012006 and 05000353/2012006)

Dear Mr. Pacilio:

On August 15, 2012, the U. S. Nuclear Regulatory Commission (NRC) completed its mid-cycle performance review of the Limerick Generating station Units 1 and 2. The NRC reviewed the most recent quarterly performance indicators (PIs) in addition to inspection results and enforcement actions from July 1, 2011 through June 30, 2012. This letter informs you of the NRCs assessment of your facility during this period and its plans for future inspections at your facility. This assessment reflects the integration of the Security Cornerstone into the Inspection Manual Chapter (IMC) 0305, Operating Reactor Assessment Program.

The NRC determined the performance at Limerick Unit 1 during the most recent quarter was within the Licensee Response Column of the NRC=s Reactor Oversight Process (ROP) Action Matrix because all inspection findings had very low (i.e., green) safety significance, and all PIs indicated that your performance was within the nominal, expected range (i.e., green). There-fore, the NRC plans to conduct ROP baseline inspections at Unit 1.

The NRC determined the performance at Limerick Unit 2 during the most recent quarter was within the Regulatory Response Column of the NRC=s ROP Action Matrix because of a self-revealing finding of low to moderate safety significance (White) involving a failure by Exelon to ensure sufficient technical guidance was contained in operating procedures to: (1) ensure that a feedwater (FW) motor-operated valve (MOV) could close against expected system differential pressures; and (2) prevent operators from attempting to close FW MOVs out of sequence resulting in differential pressures for which they are not designed. As a result, two FW valves failed to fully shut resulting in a primary containment isolation valve and the reactor core isolation cooling system being inoperable for greater than their Technical Specification allowed outage time. This finding was assigned to the third quarter of 2011 (ML113410132).

On August 2, 2012, the NRC issued a supplemental inspection report and assessment follow-up letter (ML12215A272) documenting an inspection performed in accordance with Inspection Procedure (IP) 95001, Supplemental Inspection for One or Two White Inputs in a Strategic Performance Area, to review the performance of Limerick Unit 2 in addressing the White finding discussed above. The NRC concluded your actions met the objectives of IP 95001. Therefore, in accordance with the guidance in IMC 0305, the White finding will only be considered in

M. Pacilio 2 assessing plant performance for a total of four quarters. As a result, the NRC determined the performance at Limerick Unit 2 to be in the Licensee Response Column of the ROP Action Matrix beginning with the third calendar quarter of 2012.

The enclosed inspection plan lists the inspections scheduled through December 31, 2013.

Routine inspections performed by resident inspectors are not included in the inspection plan. In addition to the baseline inspections, consistent with the Agencys actions related to Fukushima, the NRC will perform TI-187, Inspection of Near-Term Task Force Recommendation 2.3 Flooding Walkdowns and TI-188, Inspection of Near-Term Task Force Recommendation 2.3 Seismic Walkdowns. We also plan to conduct independent spent fuel storage installation inspections (lSFSl) using Inspection Procedure 60855.1, Operation of an ISFSI at Operating Plants, and an infrequently performed inspection using IP 92723, Follow-Up Inspection for Three or More Severity Level IV Traditional Enforcement Violations in the Same Area in a 12-Month Period, to follow up on three traditional enforcement violations in the area of impeding the regulatory process that occurred between the 3rd quarter 2011 and the 2nd quarter 2012 (ML112550468, ML12128A373, and ML12215A272). The NRC will schedule and conduct IP 92723 when your staff has notified us of your readiness for this inspection. The inspections listed during the last nine months of the inspection plan are tentative and may be revised at the end-of-cycle performance review.

The NRC provides the inspection plan to allow for the resolution of any scheduling conflicts and personnel availability issues. The NRC will contact you as soon as possible to discuss changes to the inspection plan should circumstances warrant any changes. This inspection plan does not include security-related inspections, which will be sent via separate, non-publicly available correspondence.

In accordance with 10 CFR 2.390 of the NRC=s ARules of Practice,@ a copy of this letter will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Please contact Paul Krohn at 610-337-5120 with any questions you have regarding this letter.

Sincerely,

/RA/
