REPORT DETAILS Summary of Plant Status The Westinghouse Facility converts uranium hexafluoride (UF6) into uranium dioxide using a wet conversion process and fabricates fuel assemblies for use in commercial nuclear power reactors. During the inspection period, normal production activities were ongoing.

A. Review of Completed Confirmatory Order Commitments (Inspection Procedure 88020)

1. Review of Confirmatory Order Section V Item 11
a. The inspectors reviewed the licensees actions regarding CO (ML17221A112),Section V, Item 11. This item required that the licensee submit a letter to the NRC discussing its basis for concluding that the CO had been satisfied. The letter was to be provided within three months of completing implementation of the terms of the CO. On March 3, 2020, Westinghouse provided the NRC with a letter discussing its basis for concluding that the Confirmatory Order (CO) has been satisfied (ML20063M239). The NRC acknowledges the receipt of this letter and inspectors have verified that the corrective actions detailed in Section V of the CO were implemented as described. The results of these inspections are detailed in the following sections of this report.

b. Conclusion

Based on the review of all completed actions, the NRC concludes that Westinghouse has completed implementation of actions detailed in CO Section V. The licensee has met the requirements stated in CO Section V, Item 11, and this item is considered closed.

2. Review of Confirmatory Order Section V Item 2 (Inspection Procedure 40100)
a. Inspection Scope The inspectors reviewed the licensees actions regarding CO Section V, Item 2, which required the licensee to conduct an additional nuclear safety culture (NSC) survey by the Westinghouse corporate nuclear safety culture organization or an experienced independent third party, consistent with the depth and scope of the NSC survey completed under the Confirmatory Action Letter (CAL) dated August 11, 2016 (ML16224B082). Identified deficiencies shall be entered into the Corrective Action Program (CAP) for tracking corrective actions to completion.

The inspectors noted that the independent third-party nuclear safety culture assessment was conducted in October 2019. The survey was completed by Westinghouses global NSC organization, in accordance with BMS-NSC-3, Nuclear Safety Culture Surveys and Assessments Procedure. This organization was independent of the Westinghouse Columbia Fuel Fabrication Facility (CFFF). The assessment results were based on a pre-assessment survey of CFFF personnel and a week of direct interviews with selected CFFF personnel. The results of the survey were reviewed, and a gap analysis was performed by the Nuclear Safety Council Monitoring Panel (NSCMP). The areas identified in the gap analysis were entered in the CAP for tracking to completion. The inspectors reviewed the NSCMP meeting minutes and CAP entries to verify that any deficiencies were entered in the CAP and are being tracked under CAP 2019-16772.

The inspectors interviewed the Employee Concerns Program (ECP) manager and noted that this position is now a full-time on-site position and that a healthy number of interactions were occurring within the ECP. In addition, the inspectors noted that numerous initiatives are underway to increase employee awareness of the ECP.

b. Conclusion

The licensee completed an independent nuclear safety culture survey and any identified deficiencies were entered into the CAP to track to completion. Based on a review of the NSC survey, NSCMP minutes, and interviews with licensee management, the NRC concluded that the licensee has met the requirements as stated in the CO,Section V, Item 2. This item is considered closed.

3. Review of Confirmatory Order (CO)Section V Item 3(3) (Inspection Procedure 88020)
a. Inspection Scope The inspectors reviewed the licensees actions regarding CO Section V, Item 3(3), which required the licensee to implement improvements identified in the engineering evaluation of the calciner and calciner off-gas scrubber design and operation to determine methods to reduce uranium carry-over into the S-1030 scrubber.

For the calciner off-gas scrubber, the inspectors noted that the licensee had completed the engineering evaluation and had also completed the installation of improvements based upon the evaluation. The inspectors reviewed the evaluation and noted that the licensee completed installation of four improvements to the calciner system:

i. Automatic pH Control - Installed online pH monitoring with display in the Conversion Control Room and means to control ammonia addition to maintain pH at the desired level.

ii. Off-Gas Condenser Spray Nozzle Flow Indication - Installed a flow meter with remote indication and low flow alarm in the Conversion Control Room. This provides indication of reduced or loss of flow to the spray nozzle at the off-gas condenser.

iii. Improved Scrubber Slab Tank Level Indication - Improved the ability to accurately monitor water level in the slab tank to assure appropriate level is maintained. Improved monitoring ability via means by adding an automatic flush on the level transmitter sensing line.

iv. Scrubber Solution Temperature Indication - Provided indication of scrubber solution temperature through a display in the Conversion Control Room and high temperature alarm. This provides enhanced capability to maintain scrubber solution within the optimal operating range.

The inspectors reviewed the completed new instrumentation and controls associated with the calciner and calciner off-gas scrubber and noted that these modifications were completed on time as required by the CO.

b. Conclusion

The licensee has completed implementation of modifications to the calciner off-gas scrubber as required by CO Section V, Item 3(3). Based on the review of engineering evaluations and design changes, the NRC concludes that Westinghouse has met the requirements stated in CO Section V, Items 3(3), and this item is considered closed.

B. Summary of completed Confirmatory Order commitments The table below lists modifications to the SNM-1107 license as required by the CO and the corresponding inspection report which details the NRCs inspection of the CO Item:

CO Item Description Due Date Inspection Report (NOTE 1)
