REPORT DETAILS PLANT STATUS The American Centrifuge Plant is currently under construction, preparing for centrifuge installation for the High-Assay Low-Enriched Uranium demonstration cascade.
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 purpose of the operational safety inspection is to determine whether the material condition and as-found configuration of the site, structures, equipment, documentation, personnel, and items relied on for safety (IROFS), conform to regulations and license/certificate requirements, and are appropriate to protect worker and public safety during normal, off-normal, and accident conditions.
Operational Safety 02.01 Identification of Safety Controls and Related Programs.
The focus of the operational safety portion of the construction inspection was to validate that the appropriate activities were identified for review and that the licensee had adequately implemented their NRC-approved methodology for assignment of quality level to specific items.
* The inspectors reviewed the integrated safety analysis and the design and documentation activities associated with the service modules at the American Centrifuge Plant (ACP) to verify that design activities, control measures, and documentation met applicable regulatory and licensing requirements. The inspectors verified that design assumptions and inputs were validated and that design outputs were adequately translated into design output documents in accordance with the Quality Assurance Program Description (QAPD) and regulatory requirements.
* The inspectors reviewed Engineering Evaluation (EE) EE-3100-0003 ACP Seismic Design Values, EE-3101-0007 Existing Structure Commercial Grade Dedication Evaluation, EE-3901-0049 ACP Seismic Design Requirements, and ACP High Assay Low Enriched Uranium (HALEU) Items Relied on for Safety (IROFS) Boundary Definition Document, BDD-H-010, Rev. 0, to verify 3
 
that the appropriate quality and acceptance criteria were applied to the applicable IROFS in accordance with regulatory requirements.
* The inspectors reviewed the commercial grade dedication (CGD) program to verify that the program met applicable regulatory and licensing requirements. Specifically, the inspectors reviewed the QAPD and implementing procedures to verify that the regulatory requirements, including appropriate definitions of commercial grade item, critical characteristics, dedicating entity and dedication from 10 CFR 21.3, were adequately adopted.
* The inspectors reviewed CGD packages and the supporting documentation, including design specifications, to determine if the safety function(s) for each item for its intended use was identified. The inspectors reviewed the critical characteristics for each CGD package to determine if the characteristics identified provided reasonable assurance that the item(s) would perform the intended safety function.
OTHER AREAS 55100 - Structural Welding General Inspection Procedure The purpose of the welding inspection was to determine through direct observation whether the structural welding activities performed at the site were done in accordance with the Safety Analysis Report (SAR) and commitments to the American Welding Society (AWS)
Code. Additionally, these inspections determined whether the licensee's structural welding practices, specification, and procedures meet the requirements of the AWS Code and contract requirements.
Structural Welding General Inspection Procedure The inspectors observed welding activities and reviewed documents for the assembly of a quality level 1 (QL-1) cascade main service module (MSM) frame to verify welding and visual inspections were performed in accordance with the requirements of the American Welding Society (AWS) D1.1:2020 Structural Welding Code -

* Specifically, the inspectors reviewed work packages, welding procedures, AWS welding performance qualification test records of ironworker welders, AWS QC-1 welding inspector certifications, certified material test reports (CMTR) for electrodes and structural steel materials, and visual examination reports used for the east-side and south-end of MSM20 and 21 to determine whether materials, welding, and inspections were in accordance with the requirements of AWS D1.1.
* The inspectors reviewed Geiger Brothers Inc. (GB) work packages WP-010A and WP-010B to verify that direct visual weld inspections were signed-off and dated by the AWS QC-1 certified welding inspector, and traceability of welders was maintained after fit-up alignment tack welds and completion of welds.
* The inspectors reviewed prequalified welding procedure specification GB-D1.1-SMAW (including attached ironworkers A1 and A2 supplemental welding procedures with additional pertinent details) to verify that its contents were in 4
 
accordance with the requirements of the AWS D1.1, Section 3, titled Prequalification of WPSs.
* The inspectors reviewed CMTRs for carbon steel square tubes and plates to verify that mechanical properties and chemical analysis results were in accordance with the requirements of the AWS D1.1, Table 3.1, Prequalified Base Metal-Weld Metal Combinations for Matching Strengths.
* The inspectors reviewed CMTRs for welding electrodes to verify that mechanical properties and chemical analysis results in the as-welded condition were in accordance with the requirements of the SFA/A5.1 specification for E7018 carbon steel electrodes.
* The inspectors reviewed welder performance qualification records for five individuals of the Ironworker/AWS Welder Certification Program of North America to verify that welder qualifications on a 1 thick carbon steel plate butt joint with backing bar (B-U2a) were performed within essential variables, bend tested, and certified for all position welding in accordance with the requirements of the AWS D1.1, Section 4, Part C, Performance Qualification.
* The inspectors reviewed records of the AWS QC-1 welding inspector with certification number 02090021 to verify that certification and visual acuity were currently active in accordance with requirements of the AWS QC1:2007, Standard for AWS Certification of Welding Inspectors.
* The inspectors reviewed the Professional NDE Services Group (PNDE) Visual Weld Examination procedure QP-VT-001 to verify that the contents were in accordance with the requirements of AWS D1.1, Section 6, Inspection.
* The inspectors observed final weld surfaces and profiles and reviewed PNDE visual examination reports to determine whether acceptance of welds was performed in accordance with the requirements of the AWS D1.1, Table 6.1, Visual Inspection Acceptance Criteria.
INSPECTION RESULTS No issues were identified.
EXIT MEETINGS AND DEBRIEFS The inspectors verified no proprietary information was retained or documented in this report.
* On March 26, 2021, the inspectors presented the Exit Meeting inspection results to Kelly Fitch and other members of the licensee staff.
