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 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.
Starting on March 20, 2020, in response to the National Emergency declared by the President of the United States on the public health risks of the coronavirus (COVID-19), resident and regional inspectors were directed to begin telework and to remotely access licensee information using available technology. During this time, the resident inspectors performed periodic site visits each week, increasing the amount of time on site as local COVID-19 conditions permitted.
As part of their onsite activities, resident inspectors conducted plant status activities as described in IMC 2515, Appendix D; observed risk significant activities; and completed on site portions of IPs. In addition, resident and regional baseline inspections were evaluated to determine if all or a portion of the objectives and requirements stated in the IP could be performed remotely. If the inspections could be performed remotely, they were conducted per the applicable IP. In some cases, portions of an IP were completed remotely and on site. The inspections documented below met the objectives and requirements for completion of the IP.

OTHER ACTIVITIES
- TEMPORARY INSTRUCTIONS, INFREQUENT AND ABNORMAL 60855 - Operation of an Independent Spent Fuel Storage Installation The inspectors evaluated the licensees independent spent fuel storage installation (ISFSI) cask loading activities on March 29 through April 2, 2021. Specifically, the inspectors observed the following activities:

Lid-to-shell root pass welding
Canister processing including forced helium dehydration
Closure ring welding and non-destructive weld evaluations
Stack-up and download of the Multi-Purpose Canister (MPC) from the HI-TRAC into the storage cask (HI-STORM) and
Radiological field surveys The inspectors performed walkdowns of the ISFSI pad, including independent radiation surveys, and walkdowns of the ISFSI haul path and vertical cask transporter.
The inspectors evaluated the following:
Spent fuel selection for the cask for this loading campaign
Selected CAPs action requests
Selected 72.48 screenings and evaluations
INSPECTION RESULTS
Observation: Unit 1 Auxiliary Feedwater Discharge Valve Hand Controller Settings 71152 On April 19, 2021, while performing a control room panel walkdown the inspectors noted that the AF discharge flow control valve hand controller (HK) meter indications and the potentiometer settings did not match each other. The inspectors noted that the HKs meters indicated 70 percent +/- 2 percent while the potentiometer settings appeared to vary between 6.8 and 7.1. Upon identification, the inspectors questioned the operators on shift of the condition. The operators then entered the condition into the Corrective Action Program as CAPs 4418342 and 4418343 for 1HK-AF0031A and 38A, 1A & 1D AF to Steam Generator Setpoint Stations being set above 6.8.
To further evaluate the condition the inspectors proceeded to review the related reference documents and noted that the HKs setpoint should be 6.8 for 1AF005A/B/C/D/E/F/G/H, AF Discharge Flow Control Air Operated Valves to yield 170 gpm. Additionally, 1BOL 7.g, AF Flow Control Valves, included direction in part to apply Technical Requirement Manual (TRM) 3.7.g condition C, which states in part that:
Condition C: One or more AF Flow Control Valve(s) not capable of throttling flow as assumed in the safety analysis for Steam Generator Tube Rupture Margin to Overfill event.
(Note 2) C.1 Restore AF Flow Control Valve(s) to OPERABLE status. 30 days.
Note 2: Condition C is applicable for any AF flow control valve thats flow control pot (1HK-AF031-38A) is adjusted to a setpoint above that specified within 1BGP 100-1A or is incapable of being throttled to control flow at or below the value specified within Design Analysis for Steam Generator Tube Rupture Margin to Overfill, CN-CRA-07-47 Revision 4.
(Pot Setpoint of 6.8 - 170 gpm).
The inspectors reviewed the observations related response in the CAP products. According to the CAP notes, output voltage checks were performed and verified that the current setting would result in the desired voltage and flow. Additionally, it was reported that the meters may vary due to not being calibrated at a specific frequency. From their review the inspectors questioned why the TRM condition was not entered upon discovery as the condition appeared to be met. The inspectors identified that this failure to follow the 1BOL 7.g requirements was a performance deficiency. The deficiency was determined to be of minor significance since the output voltage was verified to result in the desired flow of 170 gpm.
Corrective actions planned by the licensee included revising operating procedures to provide guidance on when to enter the TRM action.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
On July 12, 2021, the inspectors presented the integrated inspection results to Mr. J. Kowalski, Site Vice President, and other members of the licensee staff.
On April 7, 2021, the inspectors presented the Independent Spent Fuel Storage Installation inspection results to Mr. H. Welt, Plant Manager, and other members of the licensee staff.
