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%.
