SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Byron Station, in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.
List of Findings and Violations
No findings or violations of more than minor significance were identified.
Additional Tracking Items
None.
PLANT STATUS
Unit 1 began the inspection period operating at full power. With the exception of minor reductions in power to support scheduled testing activities or small load changes requested by the transmission dispatcher, the unit remained at or near full power for the entire inspection period.
Unit 2 began the inspection period operating at full power. With the exception of minor reductions in power to support scheduled testing activities or small load changes requested by the transmission dispatcher, the unit remained at or near full power for the entire inspection period.
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. Samples were declared complete when the IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors performed activities described in IMC 2515, Appendix D, Plant Status, observed risk significant activities, and completed on-site portions of IPs. 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.

- (1) The inspectors reviewed the licensees corrective action program for potential adverse trends in spent fuel cooling filter leakage that might be indicative of a more significant safety issue on the week ending 24 September,
INSPECTION RESULTS
Observation: Repeated Leakage in Pipe Tunnel 71152S Inspectors performed a semiannual review to identify trends that might indicate the existence of a more significant safety issue. For their review, the inspectors focused on corrective action program entries for active boric acid leaks associated with auxiliary building filter vaults above the pipe tunnel. From 2020 through 2022, inspectors noted several instances of spent fuel cooling system filter leaks into their vaults, which then wetted SSCs in the pipe tunnel below. Notable examples were documented in the following condition reports:
4323495, Inactive Boric Acid Leak in Short Door Valve Aisle Blockwall, 03/03/2020
4445731, Active Leak Identified in 1FC02F Vault, 09/10/2021
4492901, Active Leak Identified in 1FC02F Vault, 04/13/2022
4513808, 1FC02F - Water Found After Removing the Filter Floor Plug, 07/29/2022 The inspectors found that some of the closure notes of the listed reports and earlier reports did not document how the issue was addressed. As part of their review, the inspectors performed a walkdown of the adjacent rooms and found white deposits at the base of the Unit 1 valve aisle wall (IR 45117343, NRC ID: U1 Valve Aisle Dried Boric Acid). After discussions with multiple departments and a review of subsequent borescope results, the inspectors identified that safety related auxiliary building ventilation (VA) ducting was being wetted with boric acid as evidenced by visible deposits. Boric acid was observed on the inside of several VA dampers, (0VA346Y, 347Y, 354Y, & 355Y) as well as external to the carbon steel ducting from the inspection images. The station tracked filter leakage targets in their boric acid corrosion control program. The station conducted cleaning and corrective repairs for a portion of the noted conditions. However, the impact to the safety related ducting was not part of the documented conditions or evaluations. Follow-up conversations with station personnel revealed that the adverse condition would not have reasonably prevented performance of the safety function. The inspectors determined that the failure to promptly identify and correct boric acid on safety related ducting was a performance deficiency and violation of Title 10 of the Code of Federal Regulations, Appendix B, Criterion XVI. The performance deficiency was determined to be of minor significance since the boric acid on this part of the VA exhaust flow path would not reasonably prevent performance of the safety function.
As a result of this observation and the station's investigations, the licensee has determined that the long-term trend of repeated leakage demonstrates further corrective actions are required to prevent future recurrence of these types of leaks. Byron has generated condition reports (IRs 4523779, 4523782, 4523784, & 4523787) for dried boric acid in each of the dampers listed. Additionally, the station updated their open corrosion evaluation (4519861, Repeated 0FC01F Leakage Long Term Solution Required) and further documented the following corrective actions to address the primary cause:
4519864, Repeated 1FC02F Leakage Long Term Solution Required
4519868, Repeated 1FC04F Leakage Long Term Solution Required
4519870, Repeated 2FC02F Leakage Long Term Solution Required
4519874, Repeated 2FC04F Leakage Long Term Solution Required,
4519876, Repeated FC Filter Leakage -A-Frame Hoist Enhancement
4519877, Repeated FC Filter Leakage - Replacement Filter Enhancement The inspectors did not identify any findings or violations of more than minor significance during their review.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
On October 13, 2022, the inspectors presented the integrated inspection results to Mr. H. Welt, Site Vice President, and other members of the licensee staff.
