Background

This report is provided in accordance with St. Lucie Unit 1 Technical Specification 6.9.1.12, "Steam Generator Tube Inspection Report" for the inspection conducted October 14-20, 2013 during the SL1-25 refueling outage . The SL1-25 outage designator is also commonly referred to as EOC-24 (End of the 2 4 h Fuel Cycle). SL1-25 was the tenth refueling outage following installation of the Babcock &

Wilcox Advanced Series PWR replacement steam generators (SGs) in 1997. At the SL1-25 refueling outage, the replacement SGs had accumulated approximately 13.85 EFPY (166.20 EFPM) of cumulative operation since replacement in 1997. Following the SL1-25 refueling outage, St. Lucie Unit 1 initially entered HOT SHUTDOWN (Mode 4) on November 1, 2013 @ 05:18, which marked the beginning of the SL1 -25 operating cycle. Therefore, the report is due to the NRC by May 01, 2014.

The SL1-25 SG tube inspections were conducted in both 'A' and 'B' SGs as described below and meet Technical Specification (TS) Section 6.8.4.1.d.2 inspection requirements for the first half of the second sequential period of 108 months.

a. The scope of inspections performed on each SG The scope of this examination is summarized in Table 1 below and is established to meet the following requirements:
a. Technical Specification 6.8.4.1 "Steam Generator (SG) Program"
b. Technical Specification 6.8.4.1.d.2 "Inspect 100% of the tubes at sequential periods of 144, 108, 72 and, thereafter, 60 effective full power months. The first sequential period shall be considered to begin after the first in-service inspection of the SGs. In addition, inspect 50% of the tubes by the refueling outage nearest the midpoint of the period and the remaining 50% by the refueling outages nearest the end of the period. No SG shall operate for more than 72 effective full power months or three refueling outages (whichever is less) without being inspected".
c. Steam Generator Management Program: Pressurized Water Reactor Steam Generator Examination Guidelines: Revision 7. EPRI, Palo Alto, CA: 2007. 1013706.

The basis for bobbin and +PointTM tube examinations is given in Table 1. Applicable industry qualified eddy current examination techniques are provided in Table 2.

Diagnostic rotating probe examinations (Special interest, SI) were completed as required based on the results of the bobbin coil.

Prior to starting the eddy current examination at the SL1-25 refueling outage in 2013, all of the previously installed hot-leg and cold-leg plugs in Steam Generator "A"and Steam Generator "B"were confirmed to be present in their correct locations and were confirmed to be free from degradation and visible signs of leakage based on the visual examination.

The plant TS requirement (TS Section 6.8.4.1.d.2) to inspect 50% of the tubes by the refueling outage nearest the midpoint of the 2nd 1SI period of 108 months has been satisfied by the October 2013 inspection.

  • Sludge Lancing
  • FOSAR (Includes post sludge lancing visual assessment and foreign object retrieval)

There are currently no known foreign objects remaining in the secondary side of the steam generators that require tracking.

Supplemental Primary Side Inspections to address Westinghouse NSAL 12-01 Issue

Description:

Visual inspection of the SGs at a foreign Westinghouse designed plant showed indications of degradation in the cladding and/or divider plate-to-channel head weld, with exposure and wastage of the channel head base material. Westinghouse issued NSAL 12-01 "Steam Generator Channel Head Degradation" on January 5, 2012 and included recommended actions for the visual inspection at other plants.

Although the degradation is not credible for St. Lucie Unit 1, a visual inspection of the primary side channel head bowl was performed in accordance with the requirements presented in Westinghouse NSAL 12-01.

Results:

Based on the visual inspections performed, no visible signs of degradation or other abnormal conditions were identified.

b. Active degradation mechanisms found (Note 1)

The SL1-25 examination results for St. Lucie Unit 1 identified mechanical wear degradation at the following locations:

  • Fan bar and connector bar tube contact points in the u-bends
  • Horizontal lattice grid tube contact points There was no evidence of corrosion degradation during any of the SL1-25 examinations.

Note 1 : "Active Degradation" is a term used in the Steam Generator Technical Specifications and is synonymous with the term "Existing Degradation" used in EPRI Report 1019038 "Steam Generator Management Program:

Steam Generator Integrity Assessment Guidelines" Revision 3, dated November 2009.

g. The results of condition monitoring, including the results of the tube pulls and in-situ testing All tubes satisfied the structural integrity and accident-induced leakage performance criteria based on the condition monitoring (CM) evaluation performed at EOC-24. No tubes required in-situ pressure testing for either tube burst or leakage. Therefore, all tubes met the structural and leakage integrity requirements of the St. Lucie Unit 1 Technical Specifications.

No tube pulls were warranted or implemented.

h. The effective plugging percentage for all plugging in each SG No tube repair methods (i.e. sleeving) are approved for St. Lucie Unit 1 that would have an effect on the effective plugging percentages. Therefore, the applicable effective plugging percentage is synonymous with the % Plugged in item f. above.
