REPORT DETAILS

4OA5 Other Activities

.1 Post-Approval Site Inspection for License Renewal (Phase 1)

a. Inspection Scope

Implementation of License Conditions and Commitments, including Aging Management Programs: The inspectors reviewed a sample of license renewal activities scheduled for the Unit 3 Spring 2016 refueling outage, which was the last outage prior to the period of extended operation (PEO). The objective of the inspection was to maximize observations of the actual implementation of license renewal activities before the beginning of the PEO (July 16, 2016), and verify that the licensee completed the necessary actions to: (a) comply with the conditions stipulated in the renewed facility operating license; (b) meet the license renewal commitments described in NUREG-1843, "Safety Evaluation Report (SER) Related to the License Renewal of the Browns Ferry Nuclear Plant, Units 1, 2,and 3" (ADAMS Accession Number ML060120453); and (c) meet the future activities, including Aging Management Programs (AMPs), described in the Updated Final Safety Analysis Report (UFSAR) supplement submitted pursuant to 10 CFR 54.21(d).

The inspectors performed a walkdown of the Unit 3 Drywell to assess general conditions of civil engineering structures and components with regard to age-related issues. The inspectors also observed visual examinations being performed on the Reactor Pressure Vessel top guide beams.

The inspectors reviewed supporting documents; conducted interviews with licensee staff; observed in-process outage activities; and performed visual inspection of structures, systems, and components (SSCs) including those not accessible during power operation. The commitment items and AMPs selected for the inspection sample are summarized below based on their description in Appendix A of the License Renewal Application. The specific inspection activities conducted for each AMP are also described below. Specific documents reviewed are also listed in the report Attachment.

Commitment Item 12 - Boiling Water Reactor Vessel Internals Program This commitment specified that the licensee will (a) inspect the reactor top guide beams prior to the PEO, and (b) implement the inspection of jet pump thermal sleeve weld TS-2 when the inspection technique is developed by the boiling water reactors vessel and internals project (BWRVIP) inspection committee.

With regard to the top guide beam inspections, the inspectors reviewed commitment completion forms, work orders (WOs), video inspection recordings, and visual examination reports to verify that the commitment was completed as described in the licensee correspondence and the NRC SER. The jet pump thermal sleeve weld TS-2 inspection; however, has not been completed as the technique has not been approved by the BWRVIP inspection committee. The inspector reviewed the licensee's commitment completion forms, and verified that procedures and administrative controls were in place to perform the inspection or engineering evaluation once approved.

Commitment Item 15 - Open-Cycle Cooling Water System Program This commitment specified that the licensee will enhance the open-cycle cooling water system program to perform confirmatory inspections of the residual heat removal service water pump pit supply piping, associated seismic restraints, and sluice gate valves prior to the PEO, and subsequently within 10 years after entering the PEO.

The inspectors reviewed commitment completion forms, and WOs to verify that the commitment was completed as described in the licensee correspondence, and the NRC SER.

Commitment Item 21 - Fire Water System Program This commitment specified that prior to the PEO, the licensee would perform flow tests, or non-intrusive examinations, to identify evidence of loss of material due to corrosion prior to the PEO.

The inspectors reviewed commitment completion forms, WOs, and ultrasonic examination reports to verify that the commitment was completed as described in the licensee correspondence, and the NRC SER.

Commitment Item 25 - One-Time Inspection Program This commitment specified that prior to the PEO, the licensee will perform a one-time inspection of ASME equivalent Class MC supports in a submerged environment of the Units 3 torus.

The inspectors reviewed commitment completion forms, and WOs to verify that the commitment was completed as described in the licensee correspondence, and the NRC SER.

The inspectors reviewed commitment completion forms, WOs, and UT reports to verify that the commitment was completed as described in the licensee correspondence, and the NRC SER.

Commitment Item 43 - Request for Additional Information RAI 2.1-2B This commitment specified that prior to the PEO, the licensee would perform a design change to qualify 12 temperature switches installed in the steam tunnel portion of the turbine building and ensure they will be protected from age-related degradation. Specifically, the licensee would make these circuits qualified for wetting and spray from a moderate/low energy line break. The inspectors reviewed commitment completion forms, and WOs to verify that the commitment was completed as described in the licensee correspondence, and the NRC SER.

Commitment Item 46 - NRC Safety Evaluation Report, Open Item OI 2.4-3 This commitment specified that prior to the PEO, the licensee would perform one-time confirmatory ultrasonic thickness measurements on a portion of the cylindrical section of the drywell.

The inspectors reviewed commitment completion forms, WOs, and UT reports to verify that the commitment was completed as described in the licensee correspondence, and the NRC SER.
