SUMMARY
OF NRCS REVIEW OF MCGUIRE 2 STEAM GENERATOR TUBE INSERVICE INSPECTION REPORT FOR THEIR SPRING 2002 OUTAGE
Dear Mr. Jamil:
By letter dated March 20, 2002, Duke Energy Corporation (the licensee) submitted a steam generator (SG) tube plugging report in accordance with McGuire Nuclear Station, Unit 2 technical specifications (TS). By letter dated May 30, 2002, the licensee submitted a SG inservice inspection outage summary report in accordance with the plants TS. By letter dated March 11, 2003, the licensee submitted a response to an Nuclear Regulatory Commission (NRC) staff request for additional information. The NRC staff has completed its review of the licensees inservice inspection report and concludes that the licensee has provided the information required by the TS and that no additional follow-up is required at this time. A copy of the NRC staffs Safety Evaluation is enclosed.
Sincerely,
/RA/

ML031740393 OFFICE PDII-1/PM PDII-1/LA PDII-1/SC NAME RMartin CHawes JNakoski DATE 06/23/03 06/23/03 06/23/03 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO EVALUATION OF STEAM GENERATOR TUBE INSPECTION REPORT DUKE ENERGY CORPORATION MCGUIRE NUCLEAR STATION, UNIT 2 DOCKET NO. 50-370 By letter dated March 20, 2002, Duke Energy Corporation (the licensee) submitted a steam generator (SG) tube plugging report in accordance with McGuire Nuclear Station Unit 2, technical specifications (TS). By letter dated May 30, 2002, the licensee submitted a SG inservice inspection outage summary report in accordance with the plants TS. These reports are related to the Spring 2002, End-of-Cycle-14, inservice inspection. By letter dated March 11, 2003, the licensee responded to an NRC request for additional information pertaining to the SG inspection findings. A summary of the NRC staffs review is provided below.
McGuire Nuclear Station, Unit 2 has four Babcock and Wilcox International CFR 80 series vertical U-bend type SGs containing 6,633 tubes each. These SGs have thermally treated Alloy 690 tubes. The tube support plates are lattice grids made of stainless steel. The tubes are hydraulically expanded over the entire length of the tubesheet in both the inlet and outlet.
During the End-of-Cycle-14 inservice inspection, 100 percent of the tubes in SGs B and C were inspected over their full length with a bobbin coil probe. In addition to the bobbin coil inspections, the licensee used a rotating pancake coil probe to inspect various special interest locations (i. e., the tube within the tubesheet in the hot and cold legs and the U-bend regions) in SGs B and C.
As a result of the inspection, no tubes were plugged. The inspection results showed that in SG B, the licensee detected 24 indications (in 24 tubes) of fan bar wear that were between 2-percent and 12-percent through-wall. These tubes were left in service because they did not exceed the TS SG tube repair criteria of 40 percent through-wall.
The licensee reported two tubes with two possible loose parts (PLP) indications that were left in service. The indications for each tube, located 7 inches above the third fan bar, were contained in both the 1999 and 2000 bobbin data but failed to meet the criteria for identification. The indications were identified as PLPs in the bobbin data and the indications were confirmed with the rotating pancake probe in 2002. These PLPs have been present for three years and there has been no associated tube degradation. The licensee did not perform any foreign object search and retrieval (FOSAR) because access to the region is limited. The licensee indicated that these PLPs were acceptable based on the absence of any indication of tube wall material loss.
In SG C, the licensee detected 44 indications of fan bar wear that were between 1-percent and 13-percent through-wall. These indications were confirmed with the rotating pancake coil. The licensee reported two tubes with two PLP indications that were left in service. These tubes are adjacent to each other, interior to the tube bundle and the indications were located 13 inches above the secondary face of the hot leg tubesheet. The licensee stated that these indications were not present in the 1999 data. A review of the historical eddy current data indicated that there are deposits on the surface of these tubes. The licensee did not perform FOSAR because access to the region is limited. The indications are above the top of tubesheet in an area having lower cross flow. There was no degradation associated with these indications.
The licensee stated that these indications were acceptable based on engineering judgment.
Based on the NRC staffs review of the information provided by the licensee, the NRC staff concludes that the information that the licensee was required to submit according to the TS has been provided and that no additional follow-up is required at this time.
