MR Number: 3-00-0025 Kewaunee 1 Date: 05/10/00 Kewaunee,Wisconsin Conference Phone Call W/ Licensee Dockets: 50-305 PWR/W-2-LP Subject: STEAM GENERATOR TUBE INSPECTION RESULTS Discussion: Kewaunee Nuclear Power Plant (KNPP) completed the cycle 23 inservice inspection of their Westinghouse Model 51 steam generators (SGs). The licensee is scheduled to replace the SGs in the Fall of 2001. Historically, significant tubesheet crevice degradation resulted in the installation of approximately 2000 Westinghouse Hybrid Expansion Joint (HEJ) sleeves during the late 80s. Since that time, approximately 500 additional ABB welded sleeves have been installed. In light of the recent Indian Point 2 tube rupture event, the licensee consulted with Framatome prior to inspecting the SGs. As a result, the licensee enhanced some inspections with a high frequency probe, performed a secondary side tube support plate flow slot examination for evidence of hourglassing and had the 1998 SG inspection data reviewed. No evidence of degradation similar to Indian Point was observed. An initial 20% sample of SG "B" HEJ laser weld repaired sleeves resulted in identification of flaws in excess of 1% and expansion of scope to 100% per Technical Specifications as reported on 5/2/00 in accordance with 10 CFR 50.72. Likewise, inspection of SG "A" hot leg crevice area exceeded 1% and was reported on 5/8/00. As a result of the inspection effort, the licensee plans to plug 37 tubes per Technical Specifications and elected to plug an additional 93 tubes as a preventative measure. Preventative plugging included six locations in SG "A" visually observed with wetted tube ends however, no detectable degradation was identified during the eddy current examination. One Westinghouse plug in SG "B" was also found wetted and will be replaced. The licensee also plans to recover about 30 tubes previously plugged in each SG. SGs "A" and "B" will be returned to service with approximately 28% tubes plugged and 25% tubes plugged respectively. KNPP SGs are analyzed to be plugged up to 30%.
