SUBJECT:

ANNUAL ASSESSMENT LETTER FOR LIMERICK GENERATING STATION, UNITS 1 AND 2 (REPORT 05000352/2019006 AND 05000353/2019006)

Dear Mr. Hanson:

The NRC has completed its end-of-cycle performance assessment of Limerick Generating Station (LGS) Units 1 and 2, reviewing performance indicators (PIs), inspection results, and enforcement actions from January 1, 2019 through December 31, 2019. This letter informs you of the NRCs assessment of your facility during this period and its plans for future inspections at your facility. The NRC concluded that overall performance at your facility preserved public health and safety.

The NRC determined the performance at LGS Units 1 and 2 during the most recent quarter was within the Licensee Response Column (Column 1) of the NRCs Reactor Oversight Process (ROP) Action Matrix in Inspection Manual Chapter 0305, Operating Reactor Assessment Program, because all inspection findings had very low safety significance (i.e., Green), and all PIs were within the expected range (i.e., Green). Therefore, the NRC plans to conduct ROP baseline inspections at your facility.

The enclosed inspection plan lists the inspections scheduled through December 31, 2021. The NRC provides the inspection plan to allow for the resolution of any scheduling conflicts and personnel availability issues. Routine inspections performed by resident inspectors are not included in the inspection plan. You should be aware that the agency is pursuing potential changes to the ROP, including changes to engineering inspections (SECY-18-0113, Recommendations for Modifying the Reactor Oversight Process Engineering Inspections) and other changes to the baseline inspection program described in SECY-19-0067, Recommendations for Enhancing the Reactor Oversight Process. Should these changes to the ROP be implemented, the engineering and other region-based inspections are subject to change in scope, as well as schedule. Furthermore, all the inspections listed during the last twelve months of the inspection plan are tentative and may be revised. The NRC will contact you as soon as possible to discuss changes to the inspection plan should circumstances warrant any changes. In addition to baseline inspections, the NRC will also conduct Inspection Procedure (IP) 37060, 10 CFR 50.69 Risk-Informed Categorization and Treatment of Structures, Systems, and Components Inspection, in February 2020; Temporary Instruction (TI) 2515/193, Hardened Containment Vent, in June 2020; IP 60854.1, Preoperational Testing of Independent Spent Fuel Storage Facility Installation at Operating Plants, in August 2021; and IP 60855.1, Operation of an Independent Spent Fuel Storage Installation at Operating Plants, in September 2021. Lastly, during calendar year 2020, the NRC will schedule an additional inspection per a revised version of TI 2515/194, Inspection of the Licensees Implementation of Industry Initiative Associated with the Open Phase Condition Design Vulnerability in Electrical Power Systems (NRC Bulletin 2012-01), for any sites who elect to implement the guidance of the Industry Initiative on Open Phase Condition, Revision 3 (ML19163A176). Licensees will be individually notified when the NRC schedules these inspections.

This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding.

Please contact me at (610) 337-5337 with any questions you have regarding this letter.

Sincerely, X /RA/
