- 1. Introduction The U.S. Nuclear Regulatory Commission (NRC or the staff) conducted an audit of Florida Power & Light Companys (FPLs or the applicants) plant-specific operating experience (OpE) related to the Turkey Point Nuclear Generating Units 3 and 4 (Turkey Point), as part of the staffs review of the Turkey Point subsequent license renewal application (SLRA) at the EXCEL Services Corporation located in Rockville, Maryland, from May 7-18, 2018. The purpose of the audit was for the NRC staff to perform an independent review of plant specific OpE to identify examples of age related degradation, as documented in the applicants corrective action program database. The regulatory bases for the audit was Title 10 of the Code of Federal Regulations, Part 54, Requirements for Renewal of Operating Licenses for Nuclear Power Plants, (10 CFR Part 54). The staff also considered the guidance contained in NUREG-2192, Rev. 0, Standard Review Plan for Review of Subsequent License Renewal Applications for Nuclear Power Plants (SRP-SLR), dated July 2017, and NUREG-2191, Rev. 0, Generic Aging Lessons Learned for Subsequent License Renewal (GALL-SLR) Report, dated July 2017.
The identified OpE examples will be further evaluated during the staffs subsequent technical review and auditing of aging management programs (AMPs), time limited aging analyses (TLAAs) and aging management review (AMR) line items. The staffs identification and evaluation of pertinent OpE and additional related documentation, provides a basis for the staffs conclusions on the ability of the applicants proposed AMPs and TLAAs to manage the effects of aging in the period of extended operation.

Relevant Documents Reviewed Document Title Revision / Date AR 00460082 2009-10422-Bare Metal Visual Inspection of the Reactor Vessel The licensee identified dried boric acid residue, staining, and general corrosion on the outside surface of the reactor vessel (RV) bottom head during baseline bare metal VE visual examinations performed in accordance with ASME Code Case N-722-x as mandated by 10 CFR 50.55a(g)(6)(ii)(E). The root cause analysis suggested that the leakage occurred from the refueling cavity seal from above when the cavity was flooded during past refueling outages, and not from the bottom mounted nozzle (BMN) penetrations. The licensee confirmed by chemical analysis that the origin of boric acid was not from the BMN leakage. The corrosion analysis has confirmed that leaving boric acid residue and rust on the RV bottom head may cause negligible corrosion rate when the plant is at ambient temperature, and will not adversely affect the bottom head base metal integrity.
04/06/2009 AR 01742043 BMI Visual Reveals Staining & General Corrosion The licensee compared the results of the required bare metal VE visual examinations performed in 2012 to the results of the 2009 examinations, and found no changes to the conditions of the RV bottom head and no evidence of pressure boundary leakage from BMN.
03/07/2012 AR 2088999 PTN3 Results of Bottom Mounted Nozzle Examination The licensee identified 47 relevant indications (staining and discoloration) in the BMN. None of the indication was related to BMN leakage. The origin of discolored streaks on RV bottom head was determined to be from previous leakage on the cavity seal, sand boxes or NIS covers.
11/05/2015 AR 1994996 Boric Acid Identified at Closure Head Nozzle Penetration #59 The licensee identified boric acid around RV upper head penetration nozzle No. 59 while performing the bare metal VE visual examinations in accordance with ASME Code Case N-729-x as mandated by 10 CFR 50.55a(g)(6)(ii)(D). The root casue analysis found residue of boric acid trailing down the CRDM column around the annulus of nozzle and down the slope on the closure head. The licensee performed supplemental volumetric leak path assessment and found no evidence of pressure boundary leakage from the penetration nozzle.
09/30/2014 Document Title Revision / Date AR 02096392 Westinghouse Technical Bulletin (TB)-07-2 Rev 3, Reactor Vessel Head Adapter Thermal Sleeve Wear The licensee noted that it will perform the visual examinations of the RV thermal sleeves for ID/OD wear in conjuction with Code Case N-729-x required volumetric examinations of the penetration nozzles.

05/06/2010 AR 01743690 AR 01748641 Both CRs address Westinghouse Technical Bulletin (TB), TB-12-5, Baffle Bolt Degradation, describing the results of apparent cause evaluation for baffle bolt failures at DC Cook Unit 2 in 2010. CRs document the applicants evaluation of the TB and actions to implement recommendations of the TB. TB recommended actions include monitoring site inspection activities for evidence of baffle bolt failure and monitoring industry activities related to evaluation of baffle bolts.
03/12/2012 03/26/2012 Document Title Revision / Date AR 01953095 CR addresses visual findings of surface damage due to abrasive wear for several lower radial support structure components at PTN Unit 3.
Abrasive wear of the surfaces was determined to be caused by foreign material that was identified during a previous outage. Vendor evaluation in the CR determined that this surface damage will not affect the integrity or functionality of these core support structure components and is not an issue for operability.
03/30/2014 AR 01953186 This CR documents the same condition as CR 01953095, specifically for the PTN 3 core barrel flange and reactor vessel core support ledge seating surfaces. The CR cites additional vendor reports for photos of these indications.
03/30/2014 AR 01972603 CR documents an error in the previous vendor fatigue calculation for the PTN baffle-former bolts. It also addresses an FSAR change based on the revised vendor analysis. Updated design cycles were incorporated into an FSAR change package, including 50.59 screen, based on the new vendor analysis.
06/17/2014 AR 01988655 CR addresses Westinghouse TB-14-5, Reactor Internals Lower Radial Support Clevis Insert Cap Screw Degradation. CR documents the applicants evaluation of the TB and actions to implement recommendations of the TB.
09/03/2014 AR 02025425 CR documents OpE evaluation regarding fuel failures at other sites due to baffle jetting. The CR documents a review of critical configuration differences for the PTN baffle-barrel assembly relative to other Westinghouse downflow configuration plants to determine if program enhancements or configuration changes are needed.
02/13/2015 AR 02124311 CR documents that the measured ligament wear for one of the control rod guide tube (CRGT) guide cards exceeds the allowable value in WCAP-17451. CR states that the CRGT guide cards were found to be acceptable for continued service; however a 100 percent re-inspection of the guide cards will need to be performed prior to 8.8 EFPY [effective full power years].
04/10/2016 Procedure Change Request (PCR) 02135601 The PCR addresses a change to the site procedure for the PTN RPV internals AMP to add the guidance in MRP 2016-001. The PCR also documents an update to FSAR Section 16.1.6 and 50.59 review based on the results of the NRC staffs assessment of the PTN RPV internals AMP for 60 years of operation.
06/02/2016 AR 02142706 AR 02143080 Both CRs address Westinghouse NSAL-16-1 regarding baffle-former bolt OpE and 10 CFR Part 21 evaluation. The NSAL documents inspections at Indian Point 2 and Salem 1, which revealed degraded baffle-former bolts. A 10 CFR Part 21 evaluation was performed for this issue, and the NSAL provides recommended actions. The PTN CRs addresses the review of NSAL-16-1 and associated OpE regarding baffle bolts for applicability to PTN.
07/08/2016 07/12/2016 AR 02152500 CR addresses Westinghouse TB-16-4 regarding OpE for fuel alignment pins with malconized surface treatment. The TB identifies fuel alignment pin surface degradation for an unnamed plant, which is not PTN. Based on review of the OpE, the TB identifies potentially susceptible plants as those that have Type 304 stainless steel pins with a malconized surface treatment; this includes PTN. CR evaluates PTN OpE with fuel alignment pins and addresses the recommendations of the TB.
8/26/2016 Document Title Revision / Date PCR 02244882 This PCR specifically updates the site procedure for the PTN RPV internals AMP to incorporate the NEI 03-08 interim industry guidance for baffle bolts provided in MRP letter MRP 2017-009, regarding baffle-former bolt inspections for PWR plants defined in NSAL-16-1; this includes PTN. PCR also notes that this interim guidance was implemented for the PTN 4 fall 2017 outage inspections.
1/16/2018 AR 02231145 CR addresses the PTN 4 baffle bolt inspection results for the PTN 4 outage in fall 2017. Per the acceptance criteria of WCAP-17887, more than one uninspectable or failed bolt per panel requires additional predictive stress evaluation. The PTN 4 baffle bolt inspection results exceeded this threshold. 2 bolts were found to have cracking indications, and 16 were suspect. All bolts remain installed and held in place by their locking mechanisms. Westinghouse analysis for the as found baffle bolting condition at PTN 4 demonstrates acceptability for one operating cycle. Additional predictive analysis will be used to establish re-inspection interval for PTN baffle bolts and address FSAR impact.
