8. Follow-up a. Inspection Scope (IP 92701)

The inspector reviewed the licensees actions taken in response to a previously identified Inspection FolIow-up Item (IFI) involving facility procedure UCD/MNRC-0043-DOC-04, Facility Modification Procedure.

b. Observations and Findings IFI 05000607/ 2020201-01 - Follow-up on the issue of the licensee revising their modification procedure to include a screening process so that minor changes and modifications can be properly documented. (Closed)

During an NRC inspection in January 2020, the inspector noted that the licensees modification procedure did not mention a process allowed by the NRC called screening which provided a method to consider a change which might be minor in nature and, therefore, did not require any further review or evaluation.

Such a change could then be screened out, but the process would provide documentation that the licensee had considered issues involved and had concluded that nothing further was required. The licensee was informed that the issue of revising the modification procedure to include a screening process would be considered an IFI and would be reviewed during a future inspection.

During the current inspection the inspector reviewed the licensees change procedure entitled, UCD/MNRC-0043-DOC-04, Facility Modification Procedure.

The inspector noted that the procedure was revised to include a new section, Section 4.5, which addressed the screening process. The screening process provided verification that some minor changes to the facility were reviewed and did not require a full 10 CFR 50.59 evaluation. The inspector confirmed that this revision to the procedure described the screening process and provided for documentation of such changes. This issue is considered closed.

c. Conclusion The inspector reviewed one previously identified IFI and it was closed.

9. Exit Interview The inspector summarized the inspection scope and results on February 4, 2021, with members of licensee management and the RSO. The inspector described the areas inspected and discussed the inspection findings.
