LR-N20-0062 Steam Generator Tube Inspection Report TS 6.9.1.10 LR-N20-0062 STEAM GENERATOR TUBE INSPECTION REPORT TS 6.9.1.10 Page 1 of 5 PSEG Nuclear LLC Salem Unit 1 INTRODUCTION In 1998 Salem Unit 1 commenced operating cycle 13 with the newly replaced steam generators from the canceled Seabrook-2 plant. Salem Unit 1 is a four (4) loop Westinghouse Pressurized Water Reactor (PWR) with Model F SGs that incorporate thermally treated Inconel 600 U-tubes.

The tube bundle consists of 5,626 tubes with an outside diameter (OD) of 0.688 inches and a nominal tube wall thickness of 0.040 inches. During SG fabrication, the tubes were hydraulically expanded over the full tubesheet depth and the first ten tube rows were thermally stress relieved after U-bend formation. The seven (7) tube support plates (TSP) are fabricated from 405 stainless steel (SS) and have broached quatrefoil tube holes. A flow distribution baffle (FDB) plate, also 405SS, between the secondary face of the tubesheet and the first tube support plate, provides top-of-tubesheet (TTS) sludge pile control. Tube support within the U-bend region is provided by three V-shaped chrome-plated Inconel 600 antivibration bars (AVBs). Attachment 2 provides a general summary of the Salem Unit 1 Model F SG Tube Support Arrangement and Terminology.

Consistent with Technical Specification (TS) 6.9.1.10, this report is being submitted within 180 days after the initial entry into HOT SHUTDOWN following completion of inspection performed in accordance with the Specification 6.8.4.i, Steam Generator Program.

This report includes:

a.

The scope of inspections performed on each SG,

b.

Degradation mechanisms found,

c.

Nondestructive examination techniques utilized for each degradation mechanism,

g.

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

h.

The primary to secondary leakage rate observed in each SG (if it is not practical to assign the leakage to an individual SG, the entire primary to secondary leakage should be conservatively assumed to be from one SG) during the cycle preceding the inspection which is the subject of the report,

d. Technical Specification 6.9.1.10.d, Location, orientation (if linear), and measured sizes (if available) of service induced indications The service induced indications detected during outage 1R25 are AVB wear, TSP wear, FBP wear, and Foreign Object wear. Attachments 6, 7, 8, and 9 provide information for the service induced indications. The TW sizing provided in Attachments 6, 7, and 8 is from EPRI ETSS 96041.1, 96043.4, and 96042.1; respectively. The TW sizing provided in Attachment 9 is from EPRI ETSS 27901.1 or 27904.1.

e. Technical Specification 6.9.1.10.e, Number of tubes plugged during the inspection outage for each degradation mechanism provides the number of tubes plugged during the inspection outage for each degradation mechanism.

f. Technical Specification 6.9.1.10.f, Total number and percentage of tubes plugged to date, and the effective plugging percentage in each steam generator provides the total number and percentage of tubes plugged to date in each steam generator. The plugging percentage and the effective plugging percentage are the same.

g. Technical Specification 6.9.1.10.g, The results of condition monitoring, including the results of tube pulls and in-situ testing The largest depth of degradation detected for AVB wear was 39% TW, TSP wear was 12% TW, FBP wear was 9% TW, and Foreign Object wear was 100% TW (reference response to 6.9.1.10.d for further details). The Foreign Object wear indication in SG 14 Tube Row 57 Column 54 near FBH, was identified as the tube responsible for primary to secondary side leakage initially identified on February 25, 2020. This tube (SG 14 Row 57 Column 54), and tubes in SG 14 at Row 57 Column 54 and Row 57 Column 54, were full length in-situ pressure tested. All tubes eddy current inspected or in-situ pressure tested met the tube integrity performance criteria in TS 6.8.4.i.b. No tube pulls were required. All tubes with detected foreign object wear were plugged (see response to 6.9.1.10.e and Attachment 9).

h. Technical Specification 6.9.1.10.h, The primary to secondary leakage rate observed in each SG (if it is not practical to assign the leakage to an individual SG, the entire primary to secondary leakage should be conservatively assumed to be from one SG) during the cycle preceding the inspection which is the subject of the report LR-N20-0062 STEAM GENERATOR TUBE INSPECTION REPORT TS 6.9.1.10 Page 5 of 5 On Tuesday February 25, 2020 at approximately 0655, operators in the Salem Unit 1 Control Room identified a rise in the primary-to-secondary leakage from radiation monitor indications.

The leak was identified in SG 14. At about 1700, with an indicated leak rate value of approximately 47 gpd, a conservative decision was made to conduct a controlled shutdown of Salem Unit 1.

i. Technical Specification 6.9.1.10.i, The calculated accident induced leakage rate from the portion of the tubes below 15.21 inches from the top of the tubesheet for the most limiting accident in the most limiting SG. In addition, if the calculated accident induced leakage rate from the most limiting accident is less than 2.16 times the maximum operational primary to secondary leakage rate, the report should describe how it was determined Response to 6.9.1.10.h provides SG 14 experienced an operational primary to secondary leak. The source of this leak was not associated the tubesheet (See response to 6.9.1.10.g).

PSEG did not observe any primary to secondary operational leakage, associated with the tubesheet, at or greater than the detection threshold of approximately one (1) gallon per day over the cycle preceding the inspection in any of the steam generators at Salem Unit 1.

Therefore, the calculated accident induced leakage rate from the most limiting accident would not be significant.

j. Technical Specification 6.9.1.10.j, The results of monitoring for tube axial displacement (slippage). If slippage is discovered, the implications of the discovery and corrective action shall be provided 100% of all in-service tubes within the tubesheet, both HL and CL, were monitored for tube axial displacement (slippage) using Bobbin coil inspections. No indications of slippage were detected.
