SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a core inspection at American Centrifuge Plant (ACP), 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.

2 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 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.

SAFETY OPERATIONS

88020 - Operational Safety

The inspector 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 70.24, 70.61, 70.62, and Chapter 11, Management Measures, of the facilitys license application, and applicable licensee procedures.

Identification of Safety Controls and Related Programs (IP Section 02.01)

The inspector selected specific process areas for inspection based on the safety basis information of the facility, the risk/safety significance of the process areas, the description of plant changes submitted to the NRC, and past plant performance documentation. For the process areas of interest, the inspector selected a sample of accident sequences in nuclear criticality safety, fire safety, and chemical safety based on the information provided in the integrated safety analysis (ISA) summary and safety basis documentation. The inspector conducted a general plant tour of each major plant operating area. The process areas and accident sequences selected for review are listed below:

  • Withdrawal Area o NCSE-FWS-002, Criticality Accidents
  • Process Building o HD1-2, Large fire in the Process Building results in a release of Uranium Hexafluoride (UF6) from damaged process equipment, centrifuges, cylinders, cold traps, chemical traps or headers o HD1-6, Large fire in the Process Building due to ongoing construction activities results in a release of UF6 from damaged process equipment, centrifuges, cylinders, cold traps, chemical traps or headers o HD7-7, Heavy rains result in shallow flooding of Process Building/Interplant Transfer Corridor/Recycle/Assembly Building/CTTF with subsequent damage, as appropriate for a given facility, to the process equipment, centrifuges, cylinders, cold traps, chemical traps or headers and release of UF6.

3 Review of Safety Controls and Related Programs (IP Section 02.02)

The inspector reviewed information related to administrative, engineered, and passive safety controls or items relied on for safety (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 were reflected in the actual conditions in the field. The specific safety controls selected for review are listed below:

  • IROFS 7.3.1.2, Combustible Material Control Program - Inside Buildings Administrative Control, (AC)
  • IROFS 7.3.1.3, Limitations on Fossil Fueled Vehicles Used in ACP Buildings, AC
  • IROFS 7.3.1.5, Non-flammable Refrigerant, Passive Engineered Control (PEC)
  • IROFS 7.3.3.2, Vehicle Access Control, AC
  • IROFS 7.3.6.4.1.4, Cold Box Design Features, PEC
  • IROFS 7.3.6.4.1.5, Cold Box Configuration, PEC
  • IROFS 7.3.6.4.1.6, Chemical Trap Design Features, PEC
  • IROFS 7.3.6.10.1.9.2 Cascade Dump Chemical Traps, PEC
  • IROFS 7.3.6.1.1.26, Cascade Dump Traps (NaF) and Withdrawal Outlet Traps (AL2O3), PEC
  • IROFS 7.3.6.4.2.1, Tails Withdrawal Cold Trap Temperature, Active Engineered Control (AEC)
  • IROFS 7.3.6.4.2.2, Tails Withdrawal Cold Trap Pressure, AEC
  • IROFS 7.3.6.4.2.3, Cold Box Fan Disconnect, Active Engineered Control, AEC
  • IROFS 7.3.6.4.2.4, Cold Box Temperature, AEC
  • IROFS 7.3.6.11.2.4, Cold Box Fan Control, AEC
  • IROFS 7.3.6.4.3.1, Cylinder Acceptance Criteria, Administrative Control, AC
  • IROFS 7.3.6.4.3.2, Cylinder Inspection, AC
  • IROFS 7.3.6.4.3.3, Cylinder Handling, AC
  • IROFS 7.3.6.4.3.4, Pigtail Handling and Storage, AC

  • IROFS 7.3.7.5, Building Finished Floor Elevation Above Storm Drainage Swales, PEC

Implementation of Safety Controls (IP Section 02.03)

For the selected safety controls listed above, the inspector 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 inspector conducted the following activities to verify the implementation of selected safety controls:

4

  • performed walkdown of the processing building to verify the implementation the related IROFS o 7.3.7.5 o 7.3.1.3 o 7.3.1.5 o 7.3.3.2
