October 27, 2020 Mr. John A. Stewart President Nuclear Fuel Services, Inc.
P.O. Box 337, MS 123 Erwin, TN 37650-0337
SUBJECT:
NUCLEAR FUEL SERVICES, INC. - U. S. NUCLEAR REGULATORY COMMISSION INTEGRATED INSPECTION REPORT NUMBER 70-143/2020-003 AND NOTICE OF VIOLATION
Dear Mr. Stewart:
This letter refers to the inspections conducted from July 1, 2020, through September 30, 2020, at the Nuclear Fuel Services (NFS) facility in Erwin, Tennessee. During that period, the U. S.
Nuclear Regulatory Commission (NRC) implemented alternative ways to complete the core inspection program for your facility when routine onsite inspections could not be performed due to the public health emergency declared by the Secretary of Health and Human Services on January 31, 2020 (as renewed on April 21, 2020, and July 23, 2020), and the National Emergency declared by the President of the United States on March 13, 2020, concerning the novel coronavirus disease (COVID-19).
The enclosed report presents the results of the inspections, which were conducted through a combination of remote reviews and onsite observations. The inspectors reviewed activities as they relate to public health and safety, the common defense and security, and compliance with the Commission's rules and regulations, as well as the conditions of your license. The inspections covered the areas of safety operations, radiological controls, facility support, and other areas.
Within these areas, the inspectors reviewed procedures and representative records remotely and conducted telephonic interviews with site personnel. In some instances, regional inspectors were able to conduct routine inspections onsite as originally planned. The resident inspector also visited the facility two or more times per week to monitor plant conditions and conduct focused inspection activities. The findings were discussed with you and members of your staff at exit meetings held on August 20, 2020; August 27, 2020; September 17, 2020; and October 20, 2020.
Based on the results of the inspections, the NRC has determined that a Severity Level IV violation of NRC requirements occurred. This violation was evaluated in accordance with the NRC Enforcement Policy. The current Enforcement Policy is included on the NRCs Web site at https://www.nrc.gov/about-nrc/regulatory/enforcement/enforce-pol.html. The violation is cited in the enclosed Notice of Violation (Notice), and the circumstances surrounding that violation are described in detail in the subject inspection report. The violation is being cited in the Notice because it is considered self-revealing and not identified by the licensee.
J. Stewart 2 The NRC has concluded that information regarding: (1) the reason for the violation(s); (2) the corrective actions that have been taken and the results achieved; and (3) the date when full compliance was achieved is already adequately addressed on the docket in the enclosed NRC inspection report. Therefore, you are not required to respond to this letter unless the description herein does not accurately reflect your corrective actions or your position. In that case, or if you choose to provide additional information, you should follow the instructions specified in the enclosed Notice.
The NRC has also determined that another Severity Level IV violation of NRC requirement occurred. Because NFS identified and corrected the violation, and because the violation was not repetitive or willful this violation is being treated as a Non-Cited Violation (NCV), consistent with Section 2.3.2 of the Enforcement Policy. This NCV is described in the subject inspection report. If you contest the violation or significance of the NCV, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC 20555-0001, with copies to: (1) the Regional Administrator, Region II; (2) the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and (3) Mr. Larry Harris, NRC Resident Inspector at NFS.
Additionally, the inspectors implemented measures during the inspection period to support the determination of reasonable assurance that the public and the environment will be adequately protected from the hazards related to the operation of your facility. These compensatory measures included activities such as supplemental reviews of licensee-submitted reports (e.g.
effluent reports, plant modification reports, and changes to the Integrated Safety Analysis Summary) and increased communications with your staff to discuss the status of plant operations.
The compensatory measures did not constitute direct inspection and were intended to address the impact of the COVID-19 public health emergency on the agencys routine oversight program, particularly on the continuous engagement with your facility via periodic site visits and in-person interactions. These proactive actions were taken to obtain additional insights into the safe operation of the facility during the COVID-19 public health emergency.
The NRC will continue evaluating the guidelines and recommendations from federal and state authorities, along with the conditions of your facility, to determine how to best conduct inspections until normality can be achieved. In the interim, the NRC plans to conduct periodic resident inspector visits to the site and gradually increase their presence, as appropriate. The NRC will also maintain compensatory measures and frequent communications with your staff to discuss regulatory compliance matters and gather information to inform the decisions about future inspections.
In accordance with Title 10 of the Code of Federal Regulations, Section 2.390 of the NRC's "Rules of Practice and Procedure," a copy of this letter and enclosure will be made available electronically for public inspection in the NRC Public Document Room or from the NRCs Agencywide Documents Access and Management System (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html. To the extent possible, your response should not include any personal privacy or proprietary, information so that it can be made available to the Public without redaction.

REPORT DETAILS Summary of Plant Status The following facility process areas were operating during the inspection period: Naval Fuel Manufacturing Facility (FMF) and the Blended Low Enriched Uranium (BLEU) Preparation Facility (BPF), which includes the Uranium (U)-Metal, U-Oxide, Solvent Extraction and the down-blending lines.
A. Safety Operations
- 1. Resident Inspection Program - Plant Status Activities (Inspection Procedures 88135 and 88135.02)
- a. Inspection Scope During the inspection period, the inspectors performed routine walk-downs of fuel manufacturing areas housing special nuclear material (SNM), including the FMF, BPF, commercial development line areas, miscellaneous storage areas, the Wastewater Treatment Facility (WWTF), and Building 440 to assess the operational status of those areas. Primarily, the inspectors performed the walk-downs to verify that safety controls, including IROFS, were in place, properly labeled, and functional to ensure proper control of SNM.
During the walk-downs, the inspectors observed operators to verify they were knowledgeable of their duties and attentive to any alarms or annunciators at their respective stations. The inspectors also observed the interactions between supervisors and operators within the operating areas to verify that their communications supported safe operation of licensed activities. The inspectors observed activities during normal and upset conditions to verify that operators complied with procedures and station material limits.
The inspectors performed periodic tours of the outlying facility areas to verify that equipment and systems were operated safely and in compliance with the license. The inspectors focused on potential wind-borne missile hazards, potential fire hazards with combustible material storage and fire loading, hazardous chemical storage, the physical condition of bulk chemical storage tanks and piping, storage of compressed gas containers, as well as potential degradation of plant security features.
During these tours, the inspectors also observed that the required NRC Form 3, Notice to Employees, was appropriately and conspicuously posted in accordance with Title 10 of the Code of Federal Regulations (10 CFR) Part 19.11.
The inspectors interviewed plant staff assigned to different disciplines to discuss issues regarding plant equipment. Particularly, the inspectors interviewed operators, front-line managers, maintenance technicians, engineers, RP technicians, and nuclear materials control technicians to verify that each of the individuals met the applicable training and proficiency requirements in the license application for NCS posting requirements, hazards, and the operations procedures associated with their assigned duties.
The inspectors reviewed operator logbooks, standard operating procedures, maintenance records, and Letters of Authorization (i.e., temporary procedures) to obtain information concerning operating trends and activities.
4
The inspectors also reviewed the licensees implementation of corrective actions for conditions requiring temporary modifications and compensatory measures to verify adherence to plant procedures. The inspectors also reviewed changes to procedures NFS-HS-E-02, Revision 48, Nuclear Criticality Evacuation and NFS-HS-E-15, Revision 19, Emergency Medical Response to confirm changes did not conflict with regulatory or license requirements.
The inspectors discussed the results of operational and shift turnover meetings throughout the inspection period with plant personnel to gain insight into safety and operational issues. The inspectors discussed items covered during plan-of-the-day meetings and interviewed the Plant Shift Superintendent staff daily to assess the overall status of the plant and the licensees corrective actions to resolve safety-significant issues identified in these meetings.
b. Conclusion
One Severity Level IV violation of NRC requirements was identified in the area of operational safety, plant status activities. The violation is described below.
- 1) (CLOSED) Failure to Comply with Procedural Requirements for Operations in Area 200 (Notice of Violation 2020003-002)
Introduction:
The inspectors identified a self-revealing, Severity Level IV, cited violation of License Condition S-1 for the licensees failure to follow operating procedures as described in Chapter 11 of the license application.
Description:
On August 31, 2020, a trained operator assigned to the third shift manually manipulated a part of a storage vessel in Building 302, Area 200 to address a particular process condition and enable the transfer of SNM to the next processing step. As a direct result of the manual manipulation, a portion of the storage vessel broke and SNM contained in the vessel spilled on the process floor. When the storage vessel broke, part of the SNM spilled onto the lower extremities of the operator resulting in personnel contamination. Additionally, other licensee personnel were contaminated during the subsequent clean-up activities after being exposed to part of the contents of the storage vessel. The activities assigned to the operator were governed by Standard Operating Procedure (SOP)-401-02-302, Revision 051E. The manual manipulation of the storage vessel part was not the method identified in SOP-401-02-302 to address the process condition observed by the operator.
Analysis: The inspectors determined the operator manipulation of the storage vessel in Building 302, Area 200 was not authorized by SOP-401-02-302 and constituted a violation of License Condition S-1 for not handling SNM in accordance with written procedures as defined in Section 11.4 of the license application. The inspectors determined the violation was more-than-minor based on the screening criteria of IMC 0616, Fuel Cycle Safety and Safeguards Inspection Reports, Appendix B, Examples of Minor Violations. The inspectors determined the violation could reasonably be considered a precursor to a significant event per Question 1 of the screening process because it was similar to Example 1.a in that the failure to follow procedure resulted in an unsafe configuration of SNM that adversely impacted nuclear or radiological safety of equipment and personnel.
5
Specifically, the failure to follow procedure adversely impacted the containment of SNM, which is credited for the safe operation of the process, caused an unplanned contamination in the process area, and exposed a worker to licensed material.
This event did not result in serious safety consequences because: (1) the spill was contained within the Material Access Area (MAA), where physical access is controlled and radiologically control area (RCA) measures, including contamination boundaries, are normally maintained, (2) the IROFS credited for an SNM spill accident in that process area performed as designed and the performance requirements of 10 CFR 70.61 were still met based on the approved Integrated Safety Analysis (ISA) methodology for the facility, (3) the amount of licensed material spilled was below the analyzed quantities in the ISA, (4) there was no release of licensed material to the environment, (5) the RCA air sample monitors did not detect activity requiring further action, and (6) the post-event contamination of employees did not result in employee injuries or radiological/chemical exposure beyond NRC regulatory limits.
The inspectors determined that the violation was of Severity Level IV significance because the violation aligned with Example 6.2.d.2 of the Enforcement Policy in that it involved the licensees failure to maintain a control required to meet a safety margin where the failure did not result in a Severity Level I, II, or III violation. Additionally, in accordance with Section 2.2.2 of the NRC Enforcement Policy, violations that are less serious but are of more than minor concern and result in no or relatively inappreciable potential safety consequences are characterized as Severity Level IV violations.
Enforcement: License Condition S-1 states, in part, that the license is for use in accordance with the statements, representations and conditions in the application.
Chapter 11, Section 11.4, Procedure Development and Implementation, of the license application states, in part, Activities involving the handling of SNM and/or IROFS are conducted in accordance with written procedures as defined in this section.
Additionally, Section 11.4.1, Operating Procedures, of the license application states, in part, Operating procedures are documents written to authorize a) the processing of radioactive material or b) a decommissioning activity; and, within these documents detailed instructions for operation of equipment used in the process or activity, instructions for the disposition of radioactive wastes, and limits and controls established for safety purposes, including IROFS, are identified.
Contrary to the above, on August 31, 2020, the licensee failed to handle SNM in accordance with approved procedure SOP-401-02-302, Revision 051E in Building 302, Area 200. Specifically, an operator assigned failed to follow written instructions in the subject operating procedure which resulted in a spill of SNM from a material storage vessel, an unplanned contamination in a process area, and accidental worker exposure to licensed material. This violation is being treated as a cited violation consistent with Section 2.3.2 of the Enforcement Policy because it was identified through an event (i.e.
self-revealing) and not by the licensee.
The licensee took prompt corrective actions to restore compliance for this event which included: (1) evaluation of reportability to the NRC in accordance with Amendment 13 of Materials License SNM-124 (ADAMS ML20190A214), (2) increase in management oversight of the event to oversee decontamination efforts and return to operations, (3) shutdown of the affected process areas, (4) establishing additional RCA boundaries, additional personal protective equipment requirements, and radiological monitoring to further control the contamination, (5) successful decontamination of affected staff and process area, and (6) implementation of credited criticality safety controls to collect the 6
spilled SNM in safe containers. Additionally, the remaining material in the system was processed under temporary operating procedures to allow repairs and modifications of the processing equipment to reduce the likelihood of occurrence and restore licensed material containment. The process was returned to normal operation after the modifications. The licensee entered the violation in its Problem Identification, Resolution, and Correction System (PIRCS) as item number 80393 for formal investigation and resolution.
This is a violation of the requirements of License Condition S-1. A Notice of Violation is attached, and the violation will be tracked as VIO 70-143/2020003-02, Failure to Comply with Procedural Requirements for Operations in Area 200.
- 2. Resident Inspection Program - Operational Safety (Inspection Procedure 88135.04)
- a. Inspection Scope The inspectors reviewed procedures, drawings, related sections of the ISA Summary, and the license application to identify design attributes, safety functions, tests, and inspections applicable to selected safety-significant systems involved with the processing of SNM. The safety systems selected for review were associated with the ventilation system for Building 300 complex, Building 105 Laboratory, Building 301, and Building 333. The inspectors performed walk-downs of the systems to verify, in part, that system alignment and as-built configurations matched approved plant drawings and that IROFS assumptions and controls were properly implemented in the field. The inspectors also interviewed operators to confirm that plant personnel were familiar with the assumptions and controls associated with the IROFS systems and instrumentation for maintaining plant safety.
The inspectors reviewed ISAs for the selected plant systems to verify that their safety functions were not affected by outstanding design issues, temporary modifications, operator workarounds, adverse conditions, or other system-related issues. The inspectors reviewed plant conditions in the selected process areas to verify that the performance and operability of IROFS, safety-related devices, or other support systems essential to safety system performance were not degraded.
During the walk-downs, the inspectors considered the following attributes on a sampling basis and as applicable to the selected systems:
- controls in place for potential criticality, chemical, radiological, and fire safety hazards
- process vessel configurations maintained in accordance with nuclear criticality safety evaluations (NCSEs)
- correct valve position and potential functional impacts such as leakage
- electrical power availability
- major system components correctly aligned, labeled, lubricated, cooled, and ventilated
- hangers and supports correctly installed
- functional lockout/tag-put program appropriately implemented
- cabinets, cable trays, and conduits correctly installed and functional
- visible cabling in good material condition
- no interference with system performance from ancillary equipment or debris.
7
The inspectors reviewed the IROFS listed below to verify their implementation in accordance with the applicable requirements in the license application and 10 CFR 70.
The IROFS reviewed for the ventilation system associated with the Building 300 Complex, Building 105 Laboratory, Building 301, and Building 333:
- N304VENDRAIN034
- N302AIRGAP0A06
- N304XFILTERVL03
- N105FILTERVE52
- N301XVDRAIN9M01
- N333XFILTER6G21
b. Conclusion
No violations of more than minor significance were identified.
- 3. Resident Inspection Program - Nuclear Criticality Safety (Inspection Procedure 88135.02)
- a. Inspection Scope The inspectors performed weekly production area walk-downs to verify that criticality controls were in place, that personnel followed criticality station limit cards, and that containers were adequately controlled to minimize potential criticality hazards. The inspectors reviewed several criticality related IROFS for operability and interviewed operators to verify that they were knowledgeable of the requirements associated with the IROFS. During walkdowns, the inspectors observed SNM movements taking place within the facility to verify that criticality safety controls were followed.
As part of routine day-to-day activities, the inspectors reviewed entries in the licensees PIRCS associated with criticality safety aspects. The inspectors reviewed the licensees response to such entries and held discussions with NCS engineers and production personnel to understand their safety significance and verify compliance with site procedures.
The PIRCS records reviewed included 79872, 80388, and 80453.
b. Conclusion
No violations of more than minor significance were identified.
- 4. Nuclear Criticality Safety (Inspection Procedure 88015, Onsite Inspection with Remote Support)
- a. Inspection Scope Criticality Analysis (Onsite Inspection)
The inspectors evaluated selected aspects of the licensees Nuclear Criticality Safety Program to verify compliance with selected portions of 10 CFR 70, including 70.61(d),
Chapter 5 of the facilitys license application, and applicable licensee procedures.
8
The inspectors reviewed selected NCSEs and associated calculations to verify that they were consistent with the commitments in the license application. These commitments included the double contingency principle, assurance of subcriticality under normal and credible abnormal conditions with the use of subcritical margin, and technical practices and methodologies outlined in Section 5.5.2 of the license application for mass, material composition, reflection and interaction between fissile material. The inspectors focused their review on NCSEs that had not recently been reviewed in an NCS inspection. The NCSEs reviewed included 54T-13-0019, Nuclear Criticality Safety Evaluation for the Dissolution of Uranium and High Enriched Uranium Storage Columns, Revision 20; 54T-17-0006, Nuclear Criticality Safety Evaluation for the 301 Receipt Calciner Furnace, Revision 7; and those listed in Section 4 of the attachment to this report.
The inspectors reviewed the licensees generation of accident sequences to determine whether the NCSEs systematically identified normal and credible abnormal conditions in accordance with the commitments and methodologies in the license application for the analysis of process upsets. The inspectors reviewed assumptions made for upset conditions to verify they were clearly described, appropriately conservative, and matched the calculation input files. The inspectors also reviewed the protection scores assigned to IROFS in the NCSEs to determine whether they were consistent with the license application and resulted in the scenario being highly unlikely. This review was conducted for the BPF Receipt Calciner and Uranium Dissolution systems.
The inspectors interviewed licensee staff to verify that no changes were made to the validation report since the last NCS inspection.
Criticality Implementation (Onsite Inspection)
The inspectors performed walk-downs and observed operations in BPF to determine whether existing plant configuration and operations were covered by, and consistent with, the process description and safety basis in the selected NCSEs listed above. The inspectors reviewed process and system descriptions, the NCSEs, and interviewed licensee NCS engineers to verify that engineered controls established in the NCSEs were included and being implemented as specified. The engineered controls reviewed included, mass controls, (e.g., CRF-9), moderator controls (e.g., CRF-12), and geometry controls (e.g., BUM-45). The inspectors reviewed operating procedures (i.e., SOP-409, Section 8) and postings (e.g., CL-26-02) to verify that selected administrative controls established in the NCSEs were included. The administrative controls reviewed included, mass controls (e.g., BUM-29), geometry control (e.g., BPF-1, BPF-2), and piece count (e.g., CRF-2).
The inspectors reviewed the ISA Summary and supporting ISA documentation to determine whether the controls identified in the ISA were supported by technical bases in the NCSEs. These included selected controls, including those listed above for walk-downs, that were applied to the BPF Receipt Calciner and Uranium Dissolution systems.
Criticality Operational Oversight (Remote Inspection)
The inspectors reviewed NCS-related training material remotely to determine whether operator training included instruction in criticality hazards and control methods, and whether the licensees established NCS-related operator training was consistent with commitments in Section 5.3.2 of the license application, including applicable American Nuclear Society standards.
9
Additionally, the inspectors interviewed licensee NCS staff by telephone to determine whether the NCS function was involved in the development of operator training, as required. The NCS-related training records reviewed included NCS Familiarization PowerPoint for Operators.
The inspectors reviewed records of NCS audits remotely to determine whether NCS staff routinely assessed field compliance with established NCS controls. Additionally, the inspectors interviewed NCS management by telephone and reviewed procedures and schedules to verify that NCS audits of processing or storage areas of SNM were audited biennially as required by Section 5.3.4 of the license application. The records of NCS audits reviewed included the Building 105 Laboratory 6-inch Rocket NCSE audit.
Criticality Incident Response and Corrective Action (Remote Inspection)
The inspectors reviewed selected PIRCS entries remotely to verify that anomalous NCS conditions were promptly identified and entered into the PIRCS, that they received the required level of investigation, and that they were closed out consistent with license commitments and procedures. The inspectors reviewed the associated corrective actions to verify they were consistent with program procedures and appropriate to correct the condition, if preventing recurrence was not required. Additionally, the inspectors reviewed the selected PIRCS entries to assess whether the licensee followed regulatory requirements and procedures regarding plant conditions to the NRC. The entries reviewed included PIRCS 79472 and its associated investigation report.
Additional PIRCS entries reviewed are listed in the Supplementary Information section of this inspection report.
b. Conclusion
No violations of more than minor significance were identified.
- 5. Resident Inspection Program - Fire Protection (Inspection Procedure 88135.05, Quarterly Review)
- a. Inspection Scope During routine plant tours, the inspectors reviewed licensee controls for transient combustibles in selected process areas to verify compliance with the Fire Protection Program as described in Chapter 7 of the license application. The inspectors reviewed active fire impairments in selected process areas to determine if they were implemented per site procedures.
The inspectors conducted a walk-down of areas in the Building 105 Laboratory, reviewed scheduled surveillances, and pre-fire plan drawings to verify it matched the as-found condition of various fire protection components like extinguishers and postings.
The inspectors also reviewed routine audits of areas in Buildings 306 and 311.
The inspectors reviewed routinely scheduled fire safety related inspections to assure they were conducted, and that any identified deficiencies were addressed.
10
The inspections reviewed included:
- monthly safety lights inspection, Building 306 and 311
- annual sprinkler inspection, Building 105 Laboratory
- monthly control of combustibles inspection, Building 306
- fire damper inspection, Building 105 Laboratory and Building 311
- semiannual testing of CO2 fire suppression systems
- fire alarm manual pull station tests The inspectors reviewed surveillance tests for the CO2 fire suppression system in Buildings 302 and 303 to determine if the tests were performed at the required frequency and that any deficiencies were addressed. The following tests were reviewed:

- 5. Plant Modifications - Triennial (Inspection Procedure 88072, Onsite Inspection)
- a. Inspection Scope The inspectors reviewed the licensees configuration management program to determine whether the licensee established a process to evaluate, implement, and track cumulative modifications to the facility in accordance with 10 CFR 70.72 and the license application, Chapter 11, Management Measures. The inspectors reviewed configuration management procedures and interviewed licensee senior managers, supervisors, and engineers to verify that the configuration management program was being implemented in accordance with the applicable requirements.
The inspectors reviewed a selection of plant modification packages (i.e. Engineering Change Requests or ECRs) to determine whether the licensee was implementing their configuration management program as described in the license application, program procedures, and as required by 10 CFR 70.72 and 10 CFR 70.62(d). Specifically, the inspectors holistically reviewed ECRs associated with the Building 301 Receipt Calciner and Enclosure 9901 in Area 900 to verify an adequate technical basis was established and the design assumptions were accurate for the modifications as required by 10 CFR 70.72. The inspectors reviewed the ECRs to ensure modifications to the Building 301 Receipt Calciner, the Enclosure 9901 in Area 900, and their respective interfaces with other systems did not adversely impact the safety basis of the ISA or safety programs as required by 10 CFR 70.72(a)(6), or invalidate the natural phenomena hazards (NPH) structural analysis as required by 10 CFR 70.62(c). The inspectors also verified the program had adequate provisions in place to prevent plant modifications from degrading performance capabilities of IROFS or other safety controls that were part of the safety design basis.
The inspectors reviewed open work requests and temporary operating instructions for the Building 301 Receipt Calciner and Enclosure 9901 in Area 900, and interviewed plant staff to determine if the selected modifications were operated outside of their normal configuration and whether there was any adverse impact to the systems safety basis.
16
The inspectors verified that selected plant modifications met the design criteria specified in applicable modification packages. The inspectors reviewed a sample of 10 CFR 70.72 evaluations for changes made to the Building 301 Receipt Calciner and Enclosure 9901 in Area 900 to determine whether the licensee adequately evaluated the need for NRC pre-approval of select facility modifications. The inspectors reviewed applicable design basis documents to determine whether the licensing documents had been updated or were in the process of being updated promptly to reflect the modifications as required by 10 CFR 70.72(e). The inspectors reviewed the licensees document retention practices and procedures to verify compliance with the record retention requirements in 10 CFR 70.72(f). The inspectors also reviewed the training records of licensee personnel conducting the 10 CFR 70.72 evaluations to verify they were qualified to perform the evaluations in accordance with procedural requirements.
The inspectors also reviewed the selected modifications to verify the licensee properly classified minor and administrative modifications in accordance with the license application, Chapter 11, Management Measures and to verify the design basis, licensing basis and performance capabilities of IROFS had not been degraded through the modifications.
The inspectors performed walk-downs and reviewed post-modification testing documentation related to the selected modifications to verify that the system condition and tested capability were appropriate and consistent with the design basis and system functionality. The inspectors reviewed post-modification testing procedures and test results to verify the acceptance criteria for system parameters were met and valid, no unintended system interactions occurred, and IROFS performed their intended safety functions as required by 10 CFR 70.62(d). The inspectors compared the field condition with the modification packages to verify the following: the modifications were implemented in accordance with the approved design documents in the modification packages, the assumptions in the ISA were valid based on the actual configurations, and that operation of the modified processes and their management measures could be accomplished as assumed in the ISA to ensure the IROFS were available when needed.
The selected modifications included instrumentation and controls changes associated with the Building 301 Receipt Calciner and Enclosure 9901 in Area 900 to verify that the licensee had adequately established set points to prevent exceeding criticality or chemical safety exposure limits. The inspectors reviewed records and calibration stickers to verify that the measuring and test equipment used in the surveillances was properly calibrated in accordance with licensee application requirements.
The inspectors reviewed the most recent audit of the licensees configuration management program to verify that the licensee identified issues and entered them into the PIRCS in accordance with Chapter 11 of the license application. The inspectors also reviewed the licensees PIRCS to verify that issues related to the preparation and installation of plant modifications were properly categorized and addressed consistent with Chapter 11 of the license application.
b. Conclusion
No violations of more than minor significance were identified.

D. Other Areas
- 1. Licensee-Identified Violation Associated with SNM Spill in Building 302, Area 200
- a. Inspection Scope The inspectors followed up the licensees response to a spill of SNM that occurred on August 31, 2020 in Building 302, Area 200. The inspectors interviewed licensee personnel, reviewed corrective action records, and directly observed response activities in the affected process areas to verify the licensee maintained the applicable safety controls required by 10 CFR 70.
b. Conclusion
The inspection resulted in a licensee-identified, Severity Level IV, NCV of NRC requirements. The violation is described below.
As required by 10 CFR 70.62(d), the licensee shall establish management measures to ensure that controls identified as IROFS are designed, implemented, and maintained as necessary, to ensure they are available and reliable to perform their function when needed to comply with the performance requirements of 10 CFR 70.61.
Contrary to this requirement, on September 2, 2020, the licensee identified that the established management measures for IROFS-HC-18 did not ensure this control was implemented and maintained to ensure it was available and reliable to perform its function when needed to comply with the performance requirements of 10 CFR 70.61.
Specifically, procedure NFS-HS-CL-10, Nuclear Criticality Safety Fuel Manufacturing Facility, Revision 31, Sections 4.4.7 and 4.4.9 for IROFS-HC-18 requires administrative control of the placement of a quantity of licensed material mass by directing the maximum number of temporary storage locations that can be in the same location and the distance that must be maintained between grouped containers. In one instance, the licensee identified that the number of containers with licensed material that could be placed in a temporary location exceeded the limits established for IROFS-HC-18. The licensee entered the issue in the problem identification and resolution program (PIRCS 80423) and took prompt corrective actions to restore compliance with the IROFS limits once the non-compliance was identified. The inspectors determined that there were no actual safety consequences since additional safety controls were maintained to meet the performance requirements of 10 CFR 70.61(b).
This is a Severity Level IV violation consistent with Example 6.2.d.1 of the NRC Enforcement Policy. In accordance with Section 2.3.2.b of the Enforcement Policy, this violation is dispositioned as an NCV because the licensee identified and corrected the violation, and because the violation was not repetitive or willful. This violation will be tracked as NCV 2020003-01, Failure to Maintain Administrative IROFS Controls.
