REISSUE - MONTICELLO NUCLEAR GENERATING PLANT - INTEGRATED INSPECTION REPORT 05000263/2022003

Dear Christopher Domingos:

The NRC identified that the inspection report sent to you dated November 14, 2022, (ML22307A182) inadvertently omitted an inspection finding that was identified during the inspection period and discussed at the exit meeting. As a result, the NRC has re-issued the report in its entirety to contain the details of the inspection finding.

On September 30, 2022, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Monticello Nuclear Generating Plant. On October 6, 2022, the NRC inspectors discussed the results of this inspection with you and other members of your staff. The results of this inspection are documented in the enclosed report.

One finding of very low safety significance (Green) is documented in this report. This finding involved a violation of NRC requirements. We are treating this violation as a non-cited violation (NCV) consistent with Section 2.3.2 of the Enforcement Policy.

If you contest the violation or the significance or severity of the violation documented in this inspection report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN:

Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator, Region III; the Director, Office of Enforcement; and the NRC Resident Inspector at Monticello Nuclear Generating Plant.

INSPECTION RESULTS

Failure to Maintain FLEX Equipment Consistent with the Requirements of 10 CFR 50.155(c)(2)

Cornerstone Significance Cross-Cutting Aspect Report Section Mitigating Systems Green NCV 05000263/2022003-01 Open/Closed

[H.14] -

Conservative Bias 71111.15 The inspectors identified a Green, very low safety significance, non-cited violation of 10 CFR 50.155(c)(2), mitigation of beyond-design-basis (BDB) events, in that the licensee failed to reasonably protect equipment relied on for the mitigation of BDB events from the effects of natural phenomena that are equivalent in magnitude to the phenomena assumed in developing the design basis of the facility. Specifically, in a misapplication FP-BDB-EQP-01, Equipment Important to BDB Compliance, the FLEX forklift and FLEX front-end loader were routinely left unprotected from the effects of natural phenomena events for longer than allowed.

Description:

The FLEX debris removal equipment was routinely left unprotected from the effects of natural phenomena events for longer than the one shift allowed by FP-BDB-EQP-01, Equipment Important to BDB Compliance, which states, "Debris removal equipment must be returned to their designated storage location after use or by the end of shift." Vehicles and tools are stored in either the FLEX building or Warehouse 6 which meet ASCE-7

(37) requirements.

The licensee justified that as long as the work was going to continue the next day or the next week, the equipment need not be returned to BDB protective storage at the end of shift. On July 27, 2022, the FLEX forklift was removed from BDB protective storage and returned on August 3, 2022. On August 11, 2022, the FLEX forklift was removed from BDB protective storage and returned on August 15, 2022. On August 17, 2022, the FLEX forklift was removed from BDB protective storage for preventive maintenance and was returned on August 30, 2022. On August 28, 2022, the licensee documented that while performing the severe weather checklist, the step requiring verification that all FLEX equipment was in its storage location could not be performed. On September 7, 2022, the FLEX front-end loader was removed from BDB protective storage for preventative maintenance. On September 15, 2022, a rental front end loader was obtained as corrective action for not having the FLEX front-end loader available. The FLEX front-end loader was repaired and returned to its storage location on September 30, 2022.

Corrective Actions: This issue was entered into the licensee corrective action program.

Corrective Action References: 501000065942, 501000066382, 501000066386

Performance Assessment:

Performance Deficiency: The licensee failed to reasonably protect equipment relied on for the mitigation of beyond-design-basis-events from the effects of natural phenomena that are equivalent in magnitude to the phenomena assumed in developing the design basis of the facility.

Screening: The inspectors determined the performance deficiency was more than minor because it was associated with the Protection Against External Factors attribute of the Mitigating Systems cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the licensee failed to protect equipment relied on for the mitigation strategies and guidelines from the effects of natural phenomena that are equivalent in magnitude to the phenomena assumed in developing the design basis of the facility.

Significance: The inspectors assessed the significance of the finding using IMC 0609 Appendix A, The Significance Determination Process (SDP) for Findings At-Power. The finding screened to green because, although it involved equipment credited in the FLEX strategy such that FLEX functions might not be completed in accordance with existing plant procedures within the time allotted, each exposure period was less than 21 days.

Cross-Cutting Aspect: H.14 - Conservative Bias: Individuals use decision making-practices that emphasize prudent choices over those that are simply allowable. A proposed action is determined to be safe in order to proceed, rather than unsafe in order to stop. Specifically, the inspectors determined that the licensee non-conservatively interpreted the FLEX debris removal equipment requirements of FP-BDB-EQP-01, Equipment Important to BDB Compliance, which states that the front-end loader and forklift can be removed from storage for non-FLEX use but must be returned to their storage location after use or by the end of shift. The licensee justified that as long as the work was going to continue the next day or the next week, the equipment did not need to be returned to storage at the end of shift.

Enforcement:

Violation: 10 CFR 50.155 (c)(2) requires that the equipment relied on for the mitigation strategies required to mitigate beyond-design-basis external events from natural phenomena be reasonably protected from the effects of natural phenomena that are equivalent in magnitude to the phenomena assumed for developing the design basis of the facility.

Contrary to this requirement, the licensee routinely left the FLEX forklift and the FLEX front-end loader unprotected for extended periods.

Enforcement Action: This violation is being treated as a non-cited violation, consistent with Section 2.3.2 of the Enforcement Policy.

Observation: Follow-Up Review of Corrective Actions Associated with Past Documentation Annotation Pertaining to Maintenance and Surveillance Activities 71152A During the inspection period, the inspectors reviewed various documentation on recent preventive maintenance procedures and surveillance activities performed by site maintenance and operations personnel. The inspectors did not observe any issues pertaining to improper usage of markings for non-applicable steps, changing steps without appropriate approvals, or failure to perform independent verifications when required.

Observation: Corrective Actions Associated with Bump Sensitive Equipment 71152S On April 21, 2022, both fuel oil (FO) pumps, P-160B and P-160-D, were found running for emergency diesel generator (EDG) 12. Vortex considerations with both FO pumps running resulted in the inoperability but not the non-functionality of EDG 12. A vortex formed in the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of diesel operation at rated load would not have interrupted the flow of fuel from the storage tank to the day tank. The licensee returned the FO pumps to a normal lineup and declared EDG 12 operable. The licensee entered this issue into the corrective action program as QIM 50100062468, EDG FO pumps found running, EDG 12 inoperable. The licensee determined that workers likely bumped the switches while climbing a scaffold approximately three feet from the FO pump switches. The licensee protected the switches with covers to preclude future bumping.

On July 21, 2022, Xcel identified in QIM 501000064902 that Monticello had issues with status control of plant equipment that directly impacted emergency systems relied upon to protect public health and safety. The QIM established that workers were not effectively identifying and eliminating bump-sensitive component risks, consistently applying verification practices, and that marked status control areas were under-utilized to notify workers of sensitive equipment.

In August 2022, the licensee formed a multidisciplinary team to identify and recommend solutions to eliminate or reduce the risk associated with bump sensitive equipment. The team identified and initiated corrective actions for dozens of items.

Observation: Corrective Actions Associated with Power to Security Equipment 71152S On July 7, 2021, while testing security equipment, a component in the power supply failed to properly respond. The licensee entered this event into their corrective action program as quality issue management (QIM) 501000053835.The licensee performed an apparent cause evaluation and identified that the station personnel did not demonstrate adequate troubleshooting and teamwork needed to identify that a system was not properly configured.

Contributing causes included a lack of system knowledge, a lack of sensitivity to security significance, and inadequate procedures.

The inspectors verified that corrective actions to address the apparent cause and contributing causes were addressed. Corrective actions included revising the troubleshooting process to include security, revising operator rounds to include the component, training operators on these components, training security on the impacts of inoperable security equipment, revising the applicable test procedure to include clear prerequisite verification steps, updating security procedures, creating alarm response procedures associated with these components, revising maintenance surveillance procedures. The inspectors observed the testing of the components on July 7, 2022, and verified corrective actions effectively prevented recurrence of the event.
