SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) conducted readiness review inspections in the area of operational safety for operation of the Global Laser Enrichment Collector Module.
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an NRC inspection at Global Nuclear Fuel - Americas, 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 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 88020 - Operational Safety The inspectors evaluated selected aspects of the licensees Operational Safety program to verify compliance with selected portions of Title 10 of the Code of Federal Regulations, Part 70 (10 CFR 70), including 70.61, 70.62, and applicable licensee procedures.
Operational Safety Identification of Safety Controls and Related Programs (IP Section 02.01)
The inspectors reviewed all the accident sequences and items relied on for safety (IROFS) associated with the Global Laser Enrichment Collector Module, based on the information provided in the integrated safety analysis (ISA) summary. The inspectors conducted a general plant tour of each major plant operating area. The accident sequences selected for review are listed below:
TL-R-01e - Uranium Hexafluoride (UF6) Release to Gas Handling System (GHS) Room - Collector Module (CM) Failure Due to Crane Activities TL-R-01f - UF6 Release to GHS Room - CM Failure Due to Dewar Drop TL-R-01g - UF6 Release to GHS Room - CM Failure by High Pressure TL-R UF6 Release to GHS Room - CM by Uncontrolled Heating of a UF6 Plug TL-F Fire Adjacent to GHS Room or Maintenance Room TL-F Transient Combustible Fire Internal to GHS Room or Maintenance Room Review of Safety Controls and Related Programs (IP Section 02.02)
The inspectors reviewed information related to administrative, engineered, and passive safety controls or IROFS for the accident sequences selected above, including the identification of the licensees assumptions and bounding cases as they apply to each of the selected accident sequences, safety controls, or IROFS. This review was performed to verify that the controls or IROFS were available and reliable to perform their intended safety functions and that the design basis assumptions
4 were reflected in the actual conditions in the field. The specific safety controls selected for review are listed below:
TL-HF-03CG - Rupture Disk on the Carrier Gas Supply Line - Passive Engineering Control (PEC)
TL-HF-03PG - Rupture Disk for the Main Vacuum Vessel - PEC TL-HF-04a - Sense and Flee - Hydrogen Floride - Administrative Control (AC)
TL-HF-04c - Sense and Flee - Fire - AC TL-HF Crane Lift Control Process - AC TL-HF Combustible Control - AC TL-HF Protective Cover on the Collector Module - PEC TL-HF Plug Removal Process - AC TL-HF Radiant Shield - PEC TL-HF 12B Cylinder Storage Requirements - AC TL-HF-116 - Heat Transfer Low Temperature Interlock - Active Engineered Control Implementation of Safety Controls (IP Section 02.03)
For the safety controls listed above, the inspectors reviewed management measures to verify proper implementation in accordance with 10 CFR 70 and applicable sections of the license application. This review was performed to verify that selected safety controls or IROFS were present, available, and reliable to perform their safety function and that the design basis assumptions were reflected in the actual conditions in the field. The inspectors conducted the following activities to verify the implementation of selected safety controls:
performed walkdowns to verify implementation of the IROFS that are listed in section 02.02 above interviewed licensee staff regarding performance of inspections associated with IROFS TL-HF-06 interviewed licensee staff assigned to perform inspections to verify they were knowledgeable of the requirements associated with their assigned inspections observed engineers and technicians preforming procedure FTI 52220.00-F7, "Helium Isolation Valve Low Temperature Interlock," used to verify operability of IROFS TL-HF-116 Safety Control Support Programs (IP Section 02.04)
The inspectors assessed additional management measures that support the availability and reliability of the selected safety controls to verify these were implemented in accordance with 10 CFR 70 and applicable sections of the license application.
reviewed the corrective actions developed to address the issues identified in GLE's internal operational readiness review for the CM (CAP - GLE 2023021) reviewed the corrective actions associated with CAP - GLE 2023022, "Improper IROFS Documentation"
5 INSPECTION RESULTS No issues were identified.
EXIT MEETINGS AND DEBRIEFS The inspectors verified no proprietary information was retained or documented in this report.
On October 31, 2023, the inspectors presented the preliminary results to Stephen Long and other members of the GLE staff.
On December 20, 2023, the inspectors presented the NRC inspection results to Stephen Long and other members of the GLE staff.
