March 4, 2019 Mr. Bryan Senior VP, Exelon Generation Company, LLC President and CNO, Exelon Nuclear 4300 Winfield Road Warrenville, IL 60555 SUBJECT: ANNUAL ASSESSMENT LETTER FOR LASALLE COUNTY STATION, UNITS 1 AND 2 (REPORT 05000 373/20 18 00 6 AND 05000 374/20 18 00 6)

Dear Mr. Hanson:

The NRC has completed its end

-of-cycle performance assessment of LaSalle County Station, Units 1 and 2

, reviewing performance indicators (PIs)

, inspection results

, and enforcement actions from January 1, 20 18 through December 31, 20 18. This letter informs you of the NRC's 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 LaSalle County Station, Units 1 and 2

, during the most recent quarter was within the Licensee Response Column , the highest performance category of the NRC's Reactor Oversight Process (ROP) Action Matrix

, 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

, 20 20. This updated inspection plan now includes planned security inspections which were formerly transmitted under separate correspondence. 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"). 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, beginning in January 2020. 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.

This schedule includes a Temporary Instruction 2515/193 "Inspection of the Implementation of E A-13-109: Order Modifying Licenses with Regard to Reliable Hardened Containment Vents Capable of Operation under Severe Accident Conditions" inspection in November 2019. 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 10 CFR 2.390, "Public Inspections, Exemptions, Requests for Withholding."

Please contact me a t 630-829-9628 with any questions you have regarding this letter.

Sincerely,

/RA/ Kenneth Riemer, Chief Branch 1 Division of Reactor Projects Docket Nos. 50
