SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a security baseline inspection at Braidwood Station, in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.
List of Findings and Violations No findings or violations of more than minor significance were identified.
Additional Tracking Items None.
3 INSPECTION SCOPES Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2201, Security Inspection Program for Commercial Nuclear Power Reactors. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.
SAFEGUARDS 71130.07 - Security Training The inspectors evaluated the security training program through completion of the following procedure elements:
Security Training (1 Sample)
(1) 02.01 a; 02.02 a, c, d, h; 02.03 a-c; 02.04 a; 02.05 a, c; 02.06 b; 02.07 a; 02.10 71130.09 - Security Plan Changes The inspectors evaluated the security plan changes through completion of the following procedure elements:
Security Plan Changes (1 Sample)
(1) 02.01 a - c, e, f Since the last NRC baseline inspection of this program area, Security Plan Revision 18 to 19 was implemented. Based on the licensee's evaluation, and in accordance with 10 CFR 50.54(p)(2), the change(s) resulted in no decrease in safeguards effectiveness of the security plan and the revised security plan change(s) continues to meet the requirements of 10 CFR 73.55(b). The inspector(s) conducted a review of the security plan change(s) to evaluate for a potential decrease in safeguards effectiveness of the security plan; however, this review does not constitute formal NRC approval of those change(s). Therefore, the change(s) remain subject to future NRC inspection in their entirety.
INSPECTION RESULTS No findings were identified.
4 EXIT MEETINGS AND DEBRIEFS The inspectors verified no proprietary information was retained or documented in this report.
On November 20, 2025, the inspectors presented the security baseline inspection results to Patrick Krone, Security Manager, and other members of the licensee staff.
