Reference:
Letter from Michael P. Gallagher, Exelon Generation Company LLC (Exelon) to NRC Document Control Desk, dated December 9, 2014, "Application for Renewed Operating Licenses" In the Reference letter, Exelon Generation Company, LLC (Exelon) submitted the License Renewal Application (LRA) for the LaSalle County Station (LSCS), Units 1 and 2. Exelon has identified a number of corrections that need to be made to the LRA.
The Enclosure to this letter provides a description of each correction, and corresponding mark-ups to affected portions of the LRA, thereby supplementing the LSCS LRA.
Change #3 addresses License Renewal Change Request (LRCR) REGION-10, involving an operating experience example provided in the LRA for the BWR Feedwater Nozzle aging management program. This item was identified during the NRC Region Ill IP-71002 Inspection in October 2015.
This submittal has been discussed with the NRC License Renewal Project Manager for the LSCS License Renewal project.
There are no new or revised regulatory commitments contained in this letter.

RS-15-305 Enclosure Page 1 of 11 Enclosure Corrections to the LSCS LRA Introduction This enclosure contains five (5) License Renewal Application (LRA) corrections that were identified subsequent to the submittal of the LRA. In addition, a discrepancy in the response to RAI B.2.1.13-3, provided in Exelon Letter RS-15-193, is addressed. For each correction, the change is described and the affected page number(s) and portion of the LRA is provided. For clarity, entire sentences or paragraphs from the LRA, as modified by previous RAI responses, are provided with deleted text highlighted by strikethroughs and inserted text highlighted by bolded italics. Revisions to LRA tables are shown by providing excerpts from the affected tables.
RS-15-305 Enclosure Page 2 of 11 Change #1: Condenser and Air Removal System Affected LRA Section: 2.3.4.2 LRA Page Number: 2.3-146 Description of Change: An inconsistency has been identified in the Reason for Scope Determination paragraph provided in LRA Section 2.3.4.2 for the Condenser and Air Removal System. It is stated in this paragraph that the Condenser and Air Removal System is not in scope under 10 CFR 54.4(a)(2) because failure of nonsafety-related portions of the system would not prevent satisfactory accomplishment of function(s) identified for 10 CFR 54.4(a)(1).
This is contrary to the list of system intended functions for the Condenser and Air Removal System which includes 10 CFR 54.4(a)(2) intended functions for post-accident containment holdup and plate out of MSIV bypass leakage and to minimize the release of radioactive material to the environment. The Reason for Scope Determination paragraph is revised to correct this inconsistency, as shown below.
Reason for Scope Determination The Condenser and Air Removal System meets 10 CFR 54.4(a)(1) because it is a safety-related system that is relied upon to remain functional during and following design basis events.
The Condenser and Air Removal System is not in scope under 10 CFR 54.4(a)(2) because failure of nonsafety-related portions of the system would not prevent satisfactory accomplishment of function(s) identified for 10 CFR 54.4(a)(1). The Condenser and Air Removal System meets 10 CFR 54.4(a)(2) because failure of nonsafety-related portions of the system could prevent satisfactory accomplishment of function(s) identified for 10 CFR 54.4(a)(1). The Condenser and Air Removal System also meets 10 CFR 54.4(a)(3) because it is relied upon in the safety analyses and plant evaluations to perform a function that demonstrates compliance with the Commission's regulations for Environmental Qualification (10 CFR 50.49). The Condenser and Air Removal System is not relied upon in any safety analyses or plant evaluations to perform a function that demonstrates compliance with the Commission's regulations for Fire Protection (10 CFR 50.48), Anticipated Transient Without Scram (10 CFR 50.62), and Station Blackout (10 CFR 50.63).
RS-15-305 Enclosure Page 3 of 11 Change #2: Nonessential Cooling Water System Affected LRA Sections: Table 2.3.3-14 and Table 3.3.2-14 LRA Page Numbers: 2.3-94 and 3.3-183 Description of Change: Nonessential Cooling Water System Service Water Strainers 0WS01F, 1WS01F, and 2WS01F shown on license renewal boundary drawing LR-LAS-M-68, sheet 1 (dwg coordinates C, D, and E-4) are in the water supply to the Fire Water System and are in scope for 10 CFR 54.4(a)(3). The strainer bodies are included in LRA Table 2.3.3-14, Nonessential Cooling Water System Components Subject to Aging Management Review, and Table 3.3.2-14, Nonessential Cooling Water System Summary of Aging Management Evaluation, under the component type of piping, piping components, and piping elements with a component intended function of pressure boundary. However, the strainers also have an intended function to filter which was not identified as a component function in the LRA. LRA Table 2.3.3-14 is revised to add the component type of strainer element with a component intended function of filter. LRA Table 3.3.2-14 is revised to add the component type of strainer element with an intended function of filter with the corresponding material, environment, and aging management line item. These changes are shown below.

Operating Experience
- 3. The feedwater nozzles have been inspected for cracking as part of the existing augmented ISI program in accordance with the guidance in GE-NE-523-A71-0594-A, Revision 1. Each nozzle has been inspected at least twice using UT techniques recommended within GE-NE-523-A71-0594-A, Revision 1. Minor recordable indications were noted and evaluated as acceptable within the software used by the automated UT inspection equipment, consistent with ASME Code,Section XI Article IWB-3000 criteria, during the following inspections of feedwater nozzles:
The Unit 1 N4A, C, D, E, F feedwater nozzle-to-vessel welds in 2012, during refueling outage L1R14.
The Unit 2 N4A, D, E feedwater nozzle-to-vessel welds in 2011, during refueling outage L2R13.
In addition, as part of the ISI program, a reactor vessel pressure test is performed during each refueling outage to verify no unacceptable reactor coolant pressure boundary leakage. These pressure tests have not identified any leakage from the feedwater nozzles.
