SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Braidwood Station, Units 1 and 2, 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
Units 1 and 2 both began the inspection period operating at full power. With the exception of minor reductions in power to support scheduled testing activities and load changes requested by the transmission system dispatcher, both units remained operating 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/readingrm/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. From January 1 - March 19, 2020, the inspectors performed plant status activities described in IMC 2515, Appendix D, Plant Status, and conducted routine reviews using IP 71152, Problem Identification and Resolution. 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 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 and during that time conducted plant status activities as described in IMC 2515, Appendix D; and observed risk significant activities when warranted. In addition, resident and regional baseline inspections were evaluated to determine if all or 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 the cases where it was determined the objectives and requirements could not be performed remotely, management elected to postpone and reschedule the inspection to a later date.

INSPECTION RESULTS
Observation: Notification of Code Nonconformance for Replacements Steam Generators 71152 The inspectors performed a detailed review of Issue Report (IR) 4272501, Notification of Code Nonconformance for Replacements Steam Generators. The manufacturer of the licensees replacement steam generators (RSGs) for Byron Unit 1 and Braidwood Unit 1 had recently identified that volumetric examination of a nozzle weld repair that was accomplished by the manufacturer prior to the delivery of the RSGs to the licensee had not been performed, contrary to American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section III, Class 1, requirements. The affected nozzles were the 3-inch diameter blowdown and recirculation nozzles. The nozzles were fabricated by weld metal buildup as permitted by NB-4244(c). The manufacturer determined that the nozzles required repair of surface indications; the manufacturers records did not indicate the depth of the excavations and no post-repair volumetric examinations were performed.Section III, Division 1, Subsection NB-4453.4 of the ASME Boiler and Pressure Vessel Code requires a volumetric exam when the excavation exceeds the lesser of 10 percent of the section thickness or 3/8 inch. For this Problem Identification and Resolution Annual Sample, the inspectors focused on assessment of the licensees corrective actions taken to date and those planned from this point forward.
The licensee performed an engineering change which included an ASME code class reconciliation for the 3-inch diameter blowdown and recirculation nozzles. This reconciliation involved a section by section evaluation applicable to nozzle weld buildups to determine the ASME Code Class 1 versus the ASME Code Class 2 requirements. The licensee determined based on their code class reconciliation that the blowdown and recirculation nozzles could be classified as ASME Code Class 2 (Subsection NC). Since Section III, Subsection NC (4453.4 and 5254), of the ASME Boiler and Pressure Vessel Code requires volumetric examination for nozzle weld buildups after weld repair only if the nozzles diameter is 6-inch or greater, this code reconciliation resolved the ASME Code nonconformance.
The inspectors concluded that the licensees actions taken in accordance with their corrective action program were reasonable given the overall safety significance of the issue. The inspectors did not identify any findings or violations of NRC requirements in the course of their review.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
- On April 15, 2020, the inspectors presented the integrated inspection results to Mr. J. Keenan, Site Vice President, and other members of the licensee staff.
