Document No.: 51-9321268-000 Palisades 1R27 2020 180-Day Steam Generator Tube Inspection Report 1.0 PURPOSE The purpose of this document is to provide the 1R27 steam generator (SG) tube inspection report in accordance with Palisades Technical Specification 5.6.8, "Steam Generator Tube Inspection Reports" [3]. The report is provided in its entirety in Section 4.0 and the appendices of this document, from which it may be copied and modified as necessary by the Palisades Licensing Department.

2.0 ASSUMPTIONS This document contains no assumptions.

3.0 INPUTS The information summarized in this report was extracted from References [ 1], and [4].

4.0 180-DAY REPORT CONTENTS Palisades Technical Specification (TS) 5.6.8, Steam Generator Tube Inspection Reports [3], requires Entergy Nuclear Operations, Inc. (ENO), to submit a report to the Nuclear Regulatory Commission (NRC) within 180 days after initial entry into mode 4 following a steam generator inspection performed in accordance with TS 5.5.8, Steam Generator (SG) Program. The report is required to address the following items:

a. The scope of inspections performed on each SG.

b. Active degradation mechanisms found.

c. Nondestructive examination techniques utilized for each degradation mechanism.

d. Location, orientation (if linear), and measured sizes (if available) of service induced indications.

e. Number of tubes plugged during the inspection outage for each degradation mechanism.

f. The total number and percentage of tubes plugged to date.

g. The results of condition monitoring, including the results of tube pulls and in-situ testing.

h. The effective plugging percentage for all plugging in each SG.

1. The results of monitoring for tube axial displacement (slippage). If slippage is discovered, the implications of the discovery and corrective action shall be provided.

Entergy and Framatome performed a SG inspection in accordance with TS 5.5.8 during the Palisades Fall 2020 refueling outage (I R27). The Palisades SGs had accrued 24.21 effective full power years (EFPY) of operation through the end of cycle 27 (i.e., 1R27) per latest cycle lengths [l] with a nominal hot leg temperature of 583°F.

This inspection was the 19th in-service inspection following SG replacement and the 3rd and final scheduled inspection in the fifth sequential inspection period (Table 4-1 ). Initial entry into mode 4 occurred on October 18, 2020; therefore, this report is required to be submitted by April 16, 2021.

The following section ("Background") briefly describes the Palisades SG design characteristics and operating history, while the subsequent Section 4.1 through Section 4.9 provides responses to each of the TS 5.6.8 questions. Appendix A provides definitions for the acronyms and abbreviations used in this report.

Background

Palisades is a Combustion Engineering (CE) PWR equipped with two CE Model 2530 replacement steam generators. These steam generators were installed in the early l 990's as replacements for the original steam generators. Each steam generator contains 8219 Inconel 600 tubes with an outer diameter of 0. 75 inches and Page 7

framatome Document No.: 51-9321268-000 Palisades 1R27 2020 180-Day Steam Generator Tube Inspection Report nominal wall thickness of 0.042 inches. The tubes are arranged in a I-inch triangular-pitch pattern comprised of 138 rows and 165 columns. The tubes in rows 1 through 18 are ofu-bend design with a minimum bend radius of 2.5 inches (row 1) and maximum radius of 11 inches (row 18). The tubes in Rows 19 through 138 are of"square-bend" design consisting of two 90 degree bends of constant radius with a straight horizontal section of tubing of varying length between the two bends. The tubes were explosively expanded throughout the full tubesheet depth and are supported by several structures which include horizontal eggcrate supports, diagonal bars, and vertical strap supports. All of the support structures were fabricated with stainless steel. The general layout of the steam generator internals and associated nomenclature are provided in Appendix B.

Notes:

1. Estimate

2. Permanent shutdown and decommissioning is planned after the completion of the fuel cycle 28. No inspections are planned or required after 1R27. The cycle length and a 1R28 outage are shown only to illustrate regulatory compliance for operating duration.

Figure 4-1 details all ECT and plug visual inspections performed.

ECT Inspection A summary of the ECT inspections performed is provided in Table 4-2.

Primary Side Visual Inspections The primary side work activities include visual examination of the primary channel head and all installed tube plugs. The purpose of the as-found and as-left visual examination of the primary channel heads (both H/L and C/L) is to assess general material condition, to identify and remove foreign objects, if any and to complete the cladding inspection in accordance with the Framatome procedure for bowl inspections to address Nuclear Safety Advisory Letter NSAL-12-1. Additional detail is available in Reference [ 1]. No anomalous conditions were identified during these inspections. All plugs were present in the proper location and no degradation was observed.

All visually-accessible passages between tubes were viewed from the tube bundle periphery on each leg. All findings were documented in the Framatome foreign object tracking system (FOTS). Additional detail is available in Reference [ 1]

2. The sizing performance of ETSS H-21410.1 with respect to circumferential depth profiling of ODSCC is described by EPRI TR-107197-P1, which utilized the same sizing methodology as ETSS H-21410.1. The performance parameters are as follows: Depth

framatome Document No.: 51-9321268-000 Palisades 1R27 2020 180-Day Steam Generator Tube Inspection Report 4.4 d) Location, orientation (if linear), and measured sizes (if available) of service induced indications The location, orientation, and measured size of axial ODSCC, axial PWSCC, circumferential ODSCC, and foreign object wear indications identified during the 1R27 outage are provided in Table 4-5, Table 4-6, Table 4-7, and Table 4-8 respectively. Due to the large number support wear indications, the required data is provided in Appendix C and Appendix D. Statistical summaries of throughwall depth, growth rates of support wear populations (i.e., diagonal bar, vertical strap, and eggcrate wear), and the number of tubes affected by support wear are provided in Table 4-9, Table 4-10, Table 4-11, and Table 4-12. In these tables, "New" refers to support wear indications that were newly reported during the 1R27 outage, and "Repeat" refers to support wear indications reported during previous outage inspection(s) and again measured during 1R27.

Axial outside diameter stress corrosion cracking (ODSCC) trends were evaluated over the last six inspections.

The maximum detected depth was bounded by predictions of the previous operational assessment. The max depth and average depths continued to follow the same trend of the previous inspections and the number of indications is the most seen since 1R22. This is not unexpected and addressed in the multi-cycle probabilistic model used in section 9.2 of [I]. A comparison of 1R23, 1R24, 1R25, 1R26, and 1R27 eddy current results revealed no transients in signal amplitudes which would suggest a degradation of data quality, and innocuous indications which were not removed from service produced similar responses from outage to outage. In addition, measurements of signal noise in regions of interest within the SGs confirm that data quality has not deteriorated with time as discussed in detail in section 9 .1 of [ 1].

All tubes satisfied performance criteria analytically.

No tube pulls were planned and none were performed.

The condition monitoring assessment concluded that the structural integrity criteria (TS 5.5.8b. l) and accident induced leakage performance criteria (TS 5.5.8b.2) were satisfied during the operating interval preceding 1R27.

Operational leakage monitoring during cycle 27 indicated stable, low level primary to secondary leakage. The indicated leakage was just above detectability with a maximum of 1.5 GPO during the cycle based on Xe-135 activity [I]. Consequently, the plant specific operational leakage performance criterion (150 GPO, TS 5.5.8b.3, LCO 3.4.13d) was also satisfied throughout the cycle.

4.8 h) The effective plugging percentage for all plugging in each SG Since no sleeving has been performed in the Palisades steam generators, the effective plugging percentage is the same as the actual plugging percentage (see Section 4.6).

4.9 i) The results of monitoring for tube axial displacement (slippage)

Potential tube axial displacement in the tubesheet (slippage or "pullout") was monitored. Algorithms were implemented in the ECT data analysis software to detect this condition. None was identified.
