SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) conducted a routine inspection of problem identification and resolution, fire protection, decommissioning performance and status reviews, occupational radiation exposure, and solid radioactive waste management and transportation.

The inspection consisted of observations by the inspectors, interviews with site personnel, a review of procedures and records, and site walk-downs. The U.S. Nuclear Regulatory Commissions (NRCs) program for overseeing the safe decommissioning of a permanently shutdown nuclear power reactor is described in Inspection Manual Chapter (IMC) 2561, Decommissioning Power Reactor Inspection Program.

List of Violations None Additional Tracking Items None

3 SITE STATUS Vermont Yankee was inspected under Category 3, Active Decommissioning (DECON), No Fuel in the Spent Fuel Pool as described in IMC 2561.

The site continued reactor building demolition by removing the refuel floor and working downward, elevation by elevation. At the end of the inspection period the building had been demolished to grade level. The demolition was monitored by air samplers in all directions and dust mitigation efforts were implemented.

INSPECTION SCOPES The inspection was conducted using the appropriate portions of the inspection procedures (IPs).

Currently approved IPs are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html. 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. The inspection was declared complete when the objectives of the IP were met, consistent with Inspection Manual Chapter (IMC) 2561, Decommissioning Power Reactor Inspection Program.

Inspection Procedure (IP) 71801 - Decommissioning Implementation and Status Status of Decommissioning (IP Section 03.01)

The inspectors performed plant walk-downs of the following locations to assess field conditions and decommissioning activities:

1) Reactor building
2) Waste loadout area On December 9 and 10, 2025, the inspectors performed walk-downs inside and outside the industrial area boundary to observe material condition and progress of decommissioning during demolition of the reactor building. The inspectors discussed current and upcoming decommissioning activities with licensee personnel.

Implementation of Regulatory and Licensing Requirements (IP Section 03.02)

The inspectors reviewed the following licensing basis documents and regulatory required document(s):

1) 10 CFR 50.75(g) file Problem Identification and Resolution (IP Section 03.02b)

The inspectors reviewed a sample of condition reports initiated between July 1, 2025, through December 31, 2025.

IP 83750 - Decommissioning Occupational Radiation Control

4 Radiological Work Planning and Execution (IP Section 03.01)

The inspectors reviewed radiation work permits (RWPs) and as low as reasonably achievable (ALARA) work plans and observed radiation protection (RP) activities associated with the following:
