RESULTS OF STEAM GENERATOR EDDY CURRENT EXAMINATIONS 9904 REFUEL OUTAGE During the April 1999 scheduled refueling outage 100% of all accessible tubes in steam generator 11 and 12 were examined fulllength as part of the inservice inspection. The examination was conducted utilizing the multifrequency eddy current technique. The inspection program was as follows:

~

1. Bobbin Coil Examinations - The bobbin coil technique was used to examine all tubes full length, except the U-Bend region of rows 1 and 2. These bobbin coil examinations were completed using magnetically biased 0.720 inch,0.700 inch and 0.680 inch diameter probes.

2. MRPC Examinations - The 0.680 inch and 0.650 inch dual motion Plus Point motorized rotating pancake coil (MRPC) technique was used to examine 100% of the U-Bend region of rows 1 and 2. The 0.720 inch 3-Coil (0.115" mid range pancake / Plus Point mid range / 0.080" high frequency shielded pancake) MRPC technique was used to examine 100% of the hot leg tubes from three inches above the secondary tube sheet face through the tube end. The 0.610 inch Dual (high / low frequency) Gimbaled Plus Point MRPC technique was used to examine the entire sleeve (from cleeve end to sleeve end) on all inservice sleeves, except for one sleeve which was obstructed, not tested and subsequently plugged.

The 0.600 inch and 0.560 inch (Plus Point mid range magnetically oiased) MRPC technique was used to examine 25% of the Asea Brown Boveri Combustion Engineering (ABBCE) Inconel 690 hot leg tube roll plugs and sleeve roll plugs.

3. Supplemental Examinations - The 0.720 inch and 0.640 inch 3-Coil MRPC technique was used to supplement the bobbin coil data to further c5aracterize all: absolute drift signals, copper deposit signals, lm other deposit signals, dent signals > 5.0 vohs at a support structure, indications not reportable > 1.5 e

volts at tube support plates, manufacturing bumish mark signals, mix residual indication signals, possible loose part signals, possible support ligament indication signals, non quantifiable indication signals, distorted indication signals, cold leg thinning indications equal to or greater than 40% through wall and cold leg thinning indications less than 40% through wall but equal to or greater than 1.5 volts.

The 0.720 inch magnetically biased 3-Coil MRPC technique was used to disposition MRPC permeability variation indications. The 0.610 inch magnetically biased Dual (high / low frequency) Gimbated Plus j

Point MRPC technique was utilized on sleeve weld indications and sleeves with excessive permeability variations.

4. Pre-Service Baseline Examinations - The 0.730 inch combination probe (bobbin / 0.115" mid range pancake / Plus Point mid range) was used to baseline examine and profile all tubes rerolled this outage.

The 0.610 inch Dual (high / low frequency) Gimbated Plus Point MRPC technique was used to examine the entire sleeve (from sleeve end to sleeve end) on all installed sleeves. The 0.610 inch magnetically biased Dual (high / low frequency) Gimbaled Plus Point MRPC technique was utilized on sleeve weld indications.

ABBCE was contracted to acquire and evaluate the eddy current data. Zetec, Inc. was subcontracted by ABBCE to perform primary manual data analysis. Framatome Technologies, Inc. was contracted to perform a completely independent evaluation of all data acquired by ABBCE utilizing manual analysis on all MRPC data and Computer Data Screening (CDS) of all bobbin coil data. The scope of all the work contracted was completed using remote positioning devices and the Zetec MlZ-30 digital test equipment along with associated acquisition and analysis software. The software utilized was Zetec, Inc. EDDYNET98 version 1.0 including Patch _E98_1.19.

l Summary results of snubber visual inspections and functional testing for Prairie Island Unit 1, per Surveillance Procedure SP 1225 during refueling Outage 19. The examinations were conducted by Prairie Island Personnel.

Visual inspections (VT-3) were performed on 100% of Unit 1 snubbers during the April 1999 outage. No snubbers were determined to be inoperable as a result of visual q

inspections. Three safety related snubbers were removed for as-found testing due to being classified as unacceptable as a result of visualinspection. These were snubbers, 1-MSH-103B (WO 9905028), which had the rod wiper seal pulled out of the bushing,1-RCVCH-1293 (WO 9905029), which was subject to the same defect, and 1-SIRH-23B (WO9905067), which had damage to the manifold block from an interference with the base plate. The first two snubbers were reclassified as acceptable after passing a j

functional test. Snubber 1-SIRH-23B was a functional test failure. This snubber j

exhibited binding when compressed to less than 1-1/4" extension. However, it was

{

dete.rnined that this deficiency would not have prevented it from performing its safety related function. The following nonconformance reports document failure findings, NCR 19991651, NCR 19991365, and ISI discrepancy report 99-0013.

In total,47 safety related snubbers were functionally tested. This includes the following types, thirty five Basic Engineers, two Paul-Munroe, two ITT-Grinnell, and eight McDowell-Wellman 900 kip S/G snubbers. Two steam generator snubber valve h^

blocks were also tested. Snubber 1-SIRH-23B (PI-271) was the only failure noted. Due to the failure, the required sample size of Basic Engineers snubbers was increased to 20%, or 34. No decrease in visual inspection interval is required by Technical Specification 4.13. All snubbers removed for testing were pre-service inspected (VT-3) per D45.4 Snubber Removal and Installation Procedure, in addition to the above testing, seven non-safety related snubbers were changed out and functionally tested, all satisfactory. The following table summarizes the snubbers tested.
