SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a Post-Approval Site Inspection for License Renewal - Phase 4 at Nine Mile Point Nuclear Station, Unit 1, 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, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

===71003 - Post-Approval Site Inspection for License Renewal
The team conducted a Phase IV license renewal inspection. The team selected seven aging management programs for evaluation based on 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 aging management programs selected, the team reviewed records, interviewed plant staff, and conducted plant walk downs to evaluate whether aging management program elements were being implemented in accordance with NRC requirements. The team evaluated the following elements of the aging management programs: 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) Buried Piping and Tanks Inspection Program
- (2) Compressed Air Monitoring Program
- (3) Fire Water System Program
- (4) Flow-Accelerated Corrosion Program
- (5) Preventive Maintenance Program
- (6) Selective Leaching of Materials Program
- (7) Structures Monitoring Program
INSPECTION RESULTS
Observation: Limitations of Selective Leaching Aging Management Program 71003 The team noted that the procedure utilized by Exelon staff for the one-time inspection of selective leaching provided limited guidance on the acceptance criteria for visual examination and hardness testing. These one-time inspections were completed in 2009 before the plant entered its period of extended operation. The procedure stated, any evidence of selective leaching, such as discoloration, validated by a hardness test shall be considered a failure of acceptance criteria. This criterion does not provide the staff with specific quantitative or qualitative criteria. Additionally, the team observed hardness testing was utilized in only a few instances. However, the team acknowledged that this met the standard in place at that time as described in the license renewal application. The licensee stated to the team that there has not been internal operating experience indicating failures due to or the presence of selective leaching in components at Nine Mile Point, Unit
EXIT MEETINGS AND DEBRIEFS
