SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Columbia Fuel Fabrication Facility, in accordance with the fuel cycle facility inspection program. This is the NRCs program for overseeing the safe operation of licensed fuel cycle facilities. Refer to https://www.nrc.gov/materials/fuel-cycle-fac.html for more information.
List of Violations No violations of more than minor significance were identified.
Additional Tracking Items None.
3 PLANT STATUS The Westinghouse Facility converts uranium hexafluoride (UF6) into uranium dioxide using a wet conversion process and fabricated fuel assemblies for use in commercial nuclear power reactors. During the inspection period, normal production activities were ongoing.
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. Inspections were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2600, Fuel Cycle Facility Operational Safety and Safeguards Inspection Program. 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.
SAFETY OPERATIONS 88015 - Nuclear Criticality Safety The inspectors evaluated selected aspects of the licensees Nuclear Criticality Safety program to verify compliance with selected portions of 10 CFR 70, including 70.24, 70.61, 70.62, Chapter 6, Nuclear Criticality Safety (NSC) Program, of the facilitys license application, and applicable licensee procedures.
Criticality Analysis (IP Section 02.01)
The inspectors interviewed licensee staff and reviewed nuclear criticality safety evaluations (CSEs), and associated assumptions and calculations, to verify compliance with 10 CFR 70 and applicable sections of the license application. Specifically, the inspectors interviewed licensee staff and reviewed the following CSEs:
CSE-17-B, "Criticality Safety Evaluation for Final Assembly Wash Pit," Rev. 8, including the review of what-if analysis sequences 1 through 6 which cover various credible and incredible sequences involving equipment failures and human errors such as assembly drops and flooding. Which including reviewing the basis for why the licensee screened certain accident sequences as incredible.
CSE-1-H, "Criticality Safety Evaluation (CSE) for the S-958 Solvent Extraction Scrubber," Rev. 10, including the review selected accident sequences involving backflow into the ducts and accumulations in the ducts. The inspectors conducted walkdowns and reviewed Drawing 301F07HV06 to verify that the inputs to the scrubber, and selected controls on those inputs, where consistent with the CSE.
4 Criticality Implementation (IP Section 02.02)
The inspectors selected engineered and administrative controls from the licensees integrated safety analysis (ISA) summary to verify proper implementation through a review of process and system descriptions, plant walkdowns, and staff interviews to verify compliance with 10 CFR 70 and applicable sections of the license application. Specifically, the inspectors interviewed licensee staff and reviewed the following controls, and their management measures, associated with the CSEs listed above and other selected areas:
FA-901, an administrative control to prevent dropped fuel assemblies, and associated procedures
VENT-901, an administrative control using gamma surveys to prevent accumulations in ductwork, associated procedures and recent completed surveys records
VENT-S1190-121, an administrative control preventing accumulations in ductwork, and associated inspection, cleanout and sampling records associated with this control, as well as implementing procedures
VENT-SOLX-101, a passive engineered control preventing backflow into ductwork, and walked down the implementation of this control
VENT-SOLX-108, a passive engineered control preventing overflow into ductwork, and walked down the implementation of this control
VENT-SOLX-109, an administrative preventing accumulation in ductwork, and recent associated inspection records and implementing procedures
VENT-SOLX-112, a passive engineered control preventing overflow into ductwork, and walked down the implementation of this control Criticality Operational Oversight (IP Section 02.03)
The inspectors assessed the NCS staffs oversight of plant operators, procedures, and operations of systems involving special nuclear material to verify compliance with 10 CFR 70 and applicable sections of the license application. Specifically, the inspectors performed the following activities:
interviewed NCS staff concerning criticality hazards and control methods, including monitoring for and cleaning out long-term accumulations in ducts; reviewed NCS oversight of accumulation cleanouts
reviewed the documentation of selected NCS weekly facility walkthrough assessments (FWAs) performed by the licensee over the last year, the FWA scheduled for 2022, and selected items identified by the licensee during the FWAs Criticality Programmatic Oversight (IP Section 02.04)
The inspectors reviewed revisions to NCS program procedures to verify compliance with 10 CFR 70 and applicable sections of the license application. Specifically, the inspectors interviewed licensee NCS staff and reviewed the following:
5
procedures, work orders and records relating to the licensee's use of nondestructive assay controls (e.g., VENT-SOLX-901)
the most recent revision to licensee procedure RA-304, Criticality Accident Alarm System Criticality Incident Response and Corrective Action (IP Section 02.05)
The inspectors reviewed the licensees criticality accident alarm system (CAAS) and corrective action program (CAP) to verify compliance with 10 CFR 70 and applicable sections of the license application, including section 6.1.8. Specifically, the inspectors observed activities, reviewed documents, and interviewed licensee staff concerning the following:
selected NCS-related CAP entries over the last year
the annual NCS evacuation drill records for 2021
the licensee's project to upgrade the CAAS, CAAS component design and CAAS performance; including review of SEP-012 and SYP-306 FACILITY SUPPORT 88050 - Emergency Preparedness The inspectors evaluated selected aspects of the licensees emergency preparedness program to determine whether the program is maintained as required by the Emergency Plan, the license and license application, and NRC requirements in 10 CFR Part 70.
Emergency Preparedness Program Review and Implementation (IP Section 02.01)
The inspectors selected the following elements that support the implementation of the licensees emergency preparedness program to verify compliance with 10CFR70(i)(3),
Chapter 9 of the license application, and the Emergency Plan. Specifically, the inspectors conducted the following inspection activities:
reviewed the plant process for evaluating plant changes and modifications that could potentially impact the emergency preparedness program

The inspectors reviewed the licensees safety-significant and internal events related to emergency preparedness to verify compliance with 10 CFR 70.22(i)(3), Chapter 9 of the license application, and the Emergency Plan.
reviewed records of site events that required a response by the emergency response organization to determine:
o if those events had been properly assessed o
if corrective actions had been developed to address any identified issues o
if any problems or deficiencies associated with the emergency plan had been identified INSPECTION RESULTS No issues were identified.
