SUBJECT:
MONTICELLO NUCLEAR GENERATING PLANT - LICENSE RENEWAL PHASE IV REPORT 05000263/2020014
Dear Mr. Conboy:
On June 10, 2020, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Monticello Nuclear Generating Plant and discussed the results of this inspection with Ms. M. Kelly, Director of Site Performance and Support and other members of your staff. The results of this inspection are documented in the enclosed report.
No findings or violations of more than minor significance were identified during this inspection.
This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding.
Sincerely,
/RA/

Inspection Report
Docket Number: 05000263 License Number: DPR-22 Report Number: 05000263/2020014 Enterprise Identifier: I-2020-014-0002 Licensee: Northern States Power Company, Minnesota Facility: Monticello Nuclear Generating Plant Location: Monticello, MN Inspection Dates: June 01, 2020 to June 10, 2020 Inspectors: J. Corujo-Sandin, Reactor Inspector G. O'Dwyer, Reactor Engineer J. Park, Reactor Inspector Approved By: Ann Marie J. Stone, Chief Engineering Branch 1 Division of Reactor Safety Enclosure
SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a License Renewal Phase IV at Monticello Nuclear Generating Plant, 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.
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 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), regional inspectors were directed to begin telework. For the inspection documented below, it was determined that the objectives and requirements stated in the IP could be performed remotely.
OTHER ACTIVITIES
- TEMPORARY INSTRUCTIONS, INFREQUENT AND ABNORMAL
===71003 - Post-Approval Site Inspection for License Renewal The team conducted this Phase IV license renewal inspection remotely. The team selected Aging Management Programs (AMPs) for evaluation considering risk insights and programs that were enhanced or new under the renewed operating license. The team also considered for selection those programs with monitoring results that were performed for the first time or those that identified examination or test results not experienced in the past. For the AMPs selected, the team reviewed records and interviewed plant staff to evaluate whether AMP elements were being implemented involving program scope, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, acceptance criteria, corrective actions, confirmation process, administrative controls, and operating experience.
The following aging management programs were evaluated by the team:
Post-Approval Site Inspection for License Renewal ===
- (1) EWI-11.01.11; Fuel Oil Chemistry
- (2) EWI-11.01.14; Buried Piping & Tanks Inspection
- (3) EWI-11.01.19; Compressed Air Monitoring
- (4) EWI-11.01.31; Protective Coating Monitoring & Maintenance Program
- (5) EWI-11.01.33; Bolting Integrity
- (6) EWI-11.01.35; Selective Leaching of Materials
INSPECTION RESULTS
No findings were identified.
EXIT MEETINGS AND DEBRIEFS
The inspectors verified no proprietary information was retained or documented in this report.
- On June 10, 2020, the inspectors presented the License Renewal Phase IV results to Ms. M. Kelly, Director of Site Performance and Support and other members of the licensee staff.
- On June 10, 2020, the inspectors presented the Technical Debrief inspection results to Mr. J. Madden, Engineering Manager and other members of the licensee staff.
