In accordance with Term and Condition (T&C) #3 of the ITS, PSEG must submit a copy of the annual trash rack bar inspection report and repair/maintenance plan.

In accordance with T&C #3 of the ITS, Attachment 1 PSEG Salem Sonar Inspection of Trash Rack - Circulating Water Intake, River Side, Salem, NJ (2025) summarizes the trash rack bar and intake inspection for 2025. The report provides images and observations from the data collected where potential maintenance to the bar rack could be necessary to address suspect bent trash rack bars on the Unit 2 intake bays (21A, 21B, 23A). Follow up inspections will confirm the exact locations and extent of repair needed, however based on the images only minor repairs are necessary and no immediate concerns were identified. Once confirmed, an engineering analysis and safety evaluation will be performed so that the work can be conducted timely and safely.

Based on the conditions and sonar report the T&Cs of the ITS continue to be satisfied.

These repairs will be performed during the next scheduled Unit 2 refueling outage in April 2026. In accordance with standard nuclear work practices, all trash rack maintenance and repairs are being tracked and scheduled through the nuclear corrective action program.

If you have any questions or require additional information, please do not hesitate to contact Richard Cary at richard.cary@pseg.com.

Mr. Henry HO PSEG-Circulating Water Engineer Mr. Seth Seely PSEG-Branch Manager-Salem Mechanical Systems Mr. Ronald Heun Jr. PSEG-Environmental Compliance and Program Manager Reference: 2025 PSEG Salem Sonar Inspections of Trash Rack-Circulating Water Intake, River Side, Salem, NJ.

Gentleman:

Land and Harbor LLC (L&H) conducted the sonar trash bar and intake survey to document silt levels in front of the PSEG Circulating Water Intake (CWI) structure on July 23 and 26, 2025.

Previous surveys were conducted on November 15 and 19, 2024.

The work was performed from the survey boat located at the intake face, delivering real-time data without affecting plant operations. The survey aligned with ongoing welding of the ice breaker guides, causing no delays, and required only one extra sonar crew visit.

The scope of work for this task was to document silt level with additional imaging planned to verify trash bar conditions at the face of CWI and outlined in proposal P25-012.07 on July 3rd 2025.

The final day of survey is planned for the high-resolution imaging to further assess the conditions of the trash bar in September.

The revised letter report now supports the cross-functional teams using the sonar inspection data with the following deliverables:

1. This report is submitted to PSEG team leaders for review.

2. Upon review a revised report will be provided for the Environmental Compliance portion of the effort.

3. A final report will be provided with any additional revisions or findings as appropriate.

The report includes reference images that display current trash rack bar conditions.

Supplementary images and data have been archived and are accessible for further review upon request.

Introduction A combination of sonar methods (different frequency and head types) are used to meet the goals of the intake inspections. Two days are typically scheduled for this survey.

September 2, 2025 Page 2 of 3 LAND AND HARBOR LLC-SUPPORTING SONAR INSPECTIONS IN CHALLENGING ENVIRONMENTS 319 8TH Ave. Haddon Heights NJ 08035 Ph: (609) 315 5800 landandharbor@gmail.com Silt level surveys utilizing scanning sonar were conducted on July 26, 2025. A follow-up inspection and verification is scheduled for September.

The survey was monitored in real time and utilized recorded data; it was performed during the operation of circulating water pumps, and no additional lockout-tagout procedures were implemented.

Summary of Field Survey and Equipment Sonar imaging interprets sound reflections to assess conditions, displaying results in real time on a computer aboard the survey boat.

Silt levels were measured with the Kongsberg MS 1000 scanning sonar head, which was mounted on the concrete deck by boat along the intake face for each bay. The survey for this section was finished in one day.

Computers capture and deliver real-time imagery for the inspection team. The survey personnel comprised a certified hydrographer, and skilled technicians experienced with intake structures to support accurate data interpretation.

The collected sonar data were systematically reviewed by the inspection team, facilitating immediate assessment of intake bay conditions and allowing for the prompt identification of any structural concerns or environmental observationssuch as sediment distribution patterns and debris accumulationwithin the survey area. Notably, no operational disruptions were reported during the course of the fieldwork, and all findings were corroborated by cross-referencing real-time imagery with previously archived data for consistency and trend analysis.

Inspection documentation and preliminary results were compiled at the conclusion of each survey day, ensuring traceability and accuracy for subsequent review. The initial analysis highlighted several minor anomalies, which are to be further investigated during any follow-up surveys. These efforts support ongoing monitoring and maintenance planning for the intake system.

Figures and Images Figures with representative images have been labeled and provided for general information and to show trash bar conditions at the face of the CWI.

All raw data is on file and available upon request. Image resolution may decrease during the post-processing stage of reports. Sharing raw data with divers and stakeholders in future applications could improve observation clarity when required.

Summary of Findings
