SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a security baseline inspection at Callaway Plant, 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.
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 inspector 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
71130.02 - Access Control
The inspector evaluated the access control program through completion of the following inspection elements:
Access Control (1 Sample)
(1)
- Tier I: 13 Requirements (02.01a-c,e; 02-02c-f; 02.03a, 02.04a,b,e; 02.05a)
- Tier II: 5 Requirements (02.06a,c; 02.08a,b,i)
- Tier III: 1 Requirement (02.09)
71130.09 - Security Plan Changes
The inspector evaluated the security plan changes through completion of the following procedure elements:
Security Plan Changes (1 Sample)
- (1) Since the last NRC baseline inspection of this program area, Security Plan Revision 13 to 14 was implemented. Based on the Ameren evaluation, and in accordance with 10 CFR 50.54(p)(2), the changes resulted in no decrease in safeguards effectiveness of the security plan and the revised security plan changes continue to meet the requirements of 10 CFR 73.55(b). The inspector conducted a review of the security plan changes to evaluate for a potential decrease in safeguards effectiveness of the security plan; however, this review does not constitute formal NRC approval of those changes. Therefore, the changes remain subject to future NRC inspection in their entirety.
