Gjrcurnferential Indications The B&W Alloy 600 rolled plugs have been inspected in the past with the rotating pancake coil. For the first time at Prairie Island, these plugs were inspected with the
+ Point coil. Circumferentialindications located at the heel of the hard ro3 region in the plug were found in three hot leg B&W Alloy 600 rolled plugs. These plugs we e replaced.
1995 F* Measurement Error l
Tube R7C64 in 22 steam generator was classified as an F'O tube in May 1995. An F*0 tube is a tube which contains indications in the original hard roll zone or in the tube end/ seal weld area and meets the F* criteria based on the length of sound original hard roll expansion region without any additional roll expansion. This tube had a single axial indication at TEH + 0.1 to + 0.2 inches which is in or below the seal weld region of the tube end. The measurement of the indication during the 1995 outage was from the tube end to the indication and then this was value was subtracted from a constant value for the original hard roll expansion to give the criteria for an F*0 tube. However, this tube did not have the normal complete 2.75 inch expansion. Upon review of previous data, this tube had been identified as a tube with a partial tube expansion in 1989 (partial tube expansions are not a problem since the design basis for structural integrity is at the tube end seal weld). The distance for F*0 criteria for the 1997 outage was conectly measured from the top of the original equipment manufacturers (OEM) hard roll down to the top of the indication. The Prairie Island Technical Specification F*
distance is 1.07 inches plus an eddy current uncertainty. The interim Prairie Island i
eddy cunent uncertainty is 0.4 inches which has been rounded up to give an F*
1 distance of 1.5 inches of indication free hard roll and no indications above the hard roll.
l The 1997 measurement for R7C64 was determined from 10 repeated examinations to be 1.45 inches of sound hard roll above the top of the indication. By letter commitment i
to the NRC dated March 15,1995, NSP committed to an eddy current measurement uncertainty of 0.2 inches to be confirmed by Prairie Island specific testing. When that testing was not completed, NSP committed to doubling the uncertainty to and applying an F* distance of 1.5 inches. Therefore, there is substantial margin in the eddy current uncertainty allowance and the indication in R7C64 does not represent a significant deviation from the Technical Specification requirement of 1.07 inches plus eddy current i
measurement uncertainty. The NRC was informed at a meeting on February 13,1997 i
that the R7C64 F'O tube did not met the 1.5 inches of sound hard roll above the indication. The tube had 1.45 inches of sound hard roll above the indication which exceeds the Technical Specification limit of 1.07 inches of sound hard roll All F*0 tubes in 21 and 22 Steam Generator were evaluated to insure that 1.5 inches of sound hard roll exists above the indication where F* is determined by eddy current measurement.
The tube R7C64 was successfully rerolled per Modification 95L486 a&ndum 1. None of the F*0 tubes in Unit 1 are in tubes with partial tube expansions.

Unit 1 - 18.9 EFPY's Unit 2 - 18.7 EFPY's HOT LEG TEMPERATURE: 590 degrees Fahrenheit The current status of each steam generator at Prairie Island is shown in the attached Table 2: " Prairie Island Steam Generator Tube Plug and Sleeve Status."
Causes of Major Tube Degradation The major cause of the degradation of tubes in the Unit 2 Steam Generators is primary water stress corrosion cracking (PWSCC) This degradation first became detectable at Prairie Island in October 1993 usir ;3 cobbin coil supplemented with RPC inspection.
Tube pulls from Prairie Island Unit 1 and rotating coil (MRPC and plus-point) of the tubes plus experience gained from other utilities provided confirmation of the type of degradation occurring in the tubesheet region. MRPC examinations of all tubes with non-quantifiable indications in the tubesheet region has been done routinely since February, 1987. The MRPC results plus a tube pull from Unit 1 have confirmed the type of degradation as PWSCC.
Also, a few tubes are being repaired due to indications of secondary side intergranular aiiack and stress corrosion cracking (IGA / SCC or ODSCC) in the tubesheet crevice region and at the top of the tubesheet associated with the region of hard sludge deposits. This degradation mechanism was first identified in Unit 2 Steam Generators in May 1995.
Comparison of Number of Defective Tubes in Unit 2 Steam Generators, May 1995 to January 1997.
sgt97u2 doc
March 5,1997 Page 4 The number of new defective tubes identified in Unit 2 Steam Generators decreased significantly because this was the second time that the tubesheet regions in Unit 2 were completely examined using + Point rotating probe technology.
{
There are no sleeves installed rn Unit 2 steam generators Condition Monitoring Condition Monitoring evaluates the as found condition of the steam generator tubing against leakage and structural integrity criteria. There were no tubes identified which exceeded the structural integrity requirement of no tube burst at three times the normal operating differential pressure. Degradation mechanisms located in the tubesheet crevice region can not burst due to the constraints of the tubesheet. Axial degradation mechanisms are not expected to burst unless the indication is greater than 0.38 inches long in the free span.
)
inEjtu Tests To demonstrate adequate leakage and structural integrity, thirty five tubes were tested in situ. Tests were done at Main Steam Line Break (MSLB) conditions for indications in the tubeehaei crevice region. Test were done at Main Steam Line Break pressure and at three times normal operating differential pressure (3dp) for indications in free span regions. The test pressure for Main Steam Line Break conditions was 2816 psig and for 3dp was 5624 psig. The list of tubes tested in situ is in Attachment 4. No tubes challenged the structural integrity criteria of 3 times normal operating differential pressure. No tubes, other than the two F* reroll tubes discussed, leaked at Main Steam Line Break pressures. Leakage from the two F* reroll tubes was determined to be 0.03 and 0.06 gallons per hour which was a small fraction of the allowable Main Steam Line Break Leakage of 5 gpm (300 gph). All tubes tested in situ were plugged.
Ooerational Assessment for Each Degradation Mechanisn
- 1. Wear at Tube Bund,3 Structural Components and Foreign Objects (Loose Parts)
There were 47 active i VB wear !ocations this outage compared to 41 last outage.
One AVB location requud plugging. It had increased from 38% to 40%. The maximum growth seen for indications which were greater than 10% last cycle was one indication at 11% growth in a tube that went from 10% to 21%. The maximum growth in indications which were greater than 20% last inspection was 6%. The sgN7u2. doc
i l
March 5.1997 Page5 i
AVB wear degradation mechanism growth rate does not challenge structural l
integrity during the next cycle. There are no detectable active wear scars due to foreign objects.
l
- 2. Thinning at the Cold Leg Tube Support Plates l
There were 214 active CLTSP thinning locations this outage compared to 239 last i
outage. Eight of these locations required plugging (one was a small voltage DSI indication which was confirmed as volumetric by + Point). The largest percent call was 50% which had increased from 29% the previous outage. The maximum l
growth seen for indications which were greater than 10% last cycle was 22%. The 95%/95% grosvth rate was 20%. The average growth rate was 3.1%. The cold leg tube support plate degradation mechanism does not challenge structural integrity during the next cycle.
l
- 3. Assessment of Secondary Side IGAISCC in the Tubesheet Region Secondary side IGA / SCC is identified as axial or volumetric indications and is plugged on detection and thus growth rates are not available. The maximum length of IGA / SCC seen in the tubesheet region was a 1.1 inch SAI in 21 SG R7C51.
However, this length was made up of 4 shorter cracks each separated by at least 0.3 inch and none of which were greater than 0.3 inches long. This indication was i
l not pressure tested in situ due to manipulator interference. However, a 0.4 SAI l
indication in 21 SG R7C35 was pressure tested at MSLB conditions in situ and there was no leakage and a higher voltage 0.6 inch indication in 22 SG R16C38 was tested several times without leakage. None of the tubes with tubesheet axial or volumetric indications not associated with the reroll problems leaked under MSLB conditions. Therefore, it is expected that secondary side IGA / SCC does not present a concern for the next cycle.
- 4. Secondary Side IGAISCC at the Top of the Tubesheet Region There were 10 volumetric or sal indications located at the top of the tubesheet.
Again these indications are plugged on detection. Each one was pressure tested in situ at MSLB conditions and at 3 times normal operating differential pressure. There was no leakage at MSLB pressure and there was no rupture at 3dp. One tube 21 SG R29C29 leaked at 3dp, but there was no change in the post pressure test ET l
signal. Therefore, none of the indications at the top of the tubesheet presented challenges to structural or leakage integrity and new indications are not expected to present challenges during the next cycle.

l March 5.1997 Page 6 i
- 5. Assessment of Primary Water Stress Corrosion Cracking at the Roll Transition Zones (PWSCC at RTZ)
Six of the approximately 250 new indications of PWSCC at RTZs were pressure tested in situ including some of the largest voltage indications. No leakage was identified. This is the second inspection using the + Point coil of the roll transition zones. This is a reduction from the last outage of about 400 RTZ indications. Since the indications did not leak, new indications are not expected to leak either and do not present leakage or structural integrity concerns during the next cycle.
- 6. Primary Water Stress Corrosion Cracking at the Low Row U-bends (PWSCC at U-bends)
This is the first time that a u-bend indication appeared in Unit 2 and required plugging. The indication was about 0.4 inches long. It did not leak or burst under 3 times normal operating pressure differential conditions. Since the + Point coil was used to examine all of the row 1 and 2 u-bends, there is reasonable assurance that u-bend degradation growth will not exceed structural and leakage integrity for the next cycle.
- 7. Secondary Side IGA / SCC at the Tube Support Plates i
All distorted indications at all tube support plates were examined by + Point coil.
There were no confirmed indications of degradation at the tube support plates not l
associated with cold leg thinning. Therefore, this degradation mechanism does not appear to be active in Unit 2.
- 8. Manufacturing Burnishing Marks in crevice regions All manufacturing burnishing marks could be traced back to 1989 and showed no change. Therefore, there does not appear to be any degradation associated with the MBMs'.
- 9. Degradation at Dsated Tube Support Plate Locations All dents > 5.0 volts were examined with + Point. No indications of degradation were found.
1
- 10. Indications at Tube Ends There is an increasing number of indications associated with the tube ends. The number has increased from 48 in 1995 to 135 in 1997. These indications are low enough in the hard roll region to meet P criteria and do not present a structural or sgt97u2. doc

- 11. Degradation in O!eeves: There are no sleeves in Unit 2.
l
- 12. Degradation in Additional Roll Expansions (Re-Rolls) l One F* reroll had an axial indication in the upper roll transition region. This indication was in 21 SG R7C27. It was pressure tested in situ and did not leak under MSLB conditions. This indication is similar to RTZ PWSCC and dces not present a structural or leakage integrity concern.

- 13. Structural D9 gradation of the Tube Support Plates l
Computerized data screening was done of all tube support plate locations looking i
for indications of significant ligament cracking. None was found.
- 14. Potential Degradation in Tube Plugs All tube plugs were examined visually. One explosive plug from 1977 had seepage l
and was replaced. All B&W plugs were examined in the hot leg with the + Point coil (first use). Three of the B&W rolled plugs contained circumferentialindications in the heel region and were replaced in accordance with BWNT recommendations to inspect each cycle and replace those with indications. An inspection at each refueling cycle is sufficient to insure the integrity of the B&W plugs. Because of the indications in the hot leg plugs, all of the cold leg B&W plugs were inspected with l
the + Point coil. No indications were found in the cold leg plugs.
Summarv of Ooerational Assessment e ~ evaluation of allindications of degradation confirms that none of the forms of l
degradation occurring presents a structural or leakage integrity concern for the next cycle of operation.

Remedial Actions l
Northern States Power has participated in utility funded research on steam generator related issues beginning with the Steam Generator Owners Group ll in 1982 and l
continuing to the pres,ent EPRI funded Steam Generator Management Project. Remedial l
actions to reduce and/or prevent tube degradation due to primary water stress corrosion cracking and secondary side IGA / SCC have been used by the industry with only limited success. Prairie Island has evaluated, and in most cases, implemented the following remedial actions:
sgt97u2 doc
l March 5.1997 Page 8 Reduced Ooeratinq.Temoerature: Prairie Island has been a low temperature plant having operated with Thot at 590 F since startup. This has slowed, but not eliminated, growth of PWSCC and IGA / SCC in the Prairie Island steam l
generators. Additional temperature reduction has not been warranted.
Chemistrv Conitot Prairie Island has used state of the art analytical equipment since startup and has followed both the original equipment manufacturer's water l
chemistry guidelines as well as the EPRI secondary water chemistry guidelines.
The amounts of material found from hideout return tests during shutdowns have i
been small. Steam generators are sludge lanced every other outage on a cycling basis with less than 80 pounds of sludge removed from the steam generator per outage. The PWSCC degradation is relatively independent of chemistry and occurs in regions of high residual stress.
i High Hvdrazine and Molar Ratio Control: These two remedial actions have been used with success in Japan. For a US plant, Prairie Island has maintained l
relatively high hydrazine levels for a long time. In May,1992, hydrazine control l
was raised to 125 +- 25 ppb.
Molar ratio control to reduce secondarv side corrosion: Molar ration control has been attempted by adjustments to steam generator blowdown resin ratios during the last operating cycle. Molar ratio control is still being evaluated. The object of molar ratio controlis to maintain the cation to anion ratio (sodium to chloride) at less than one so that free sodium hydroxide can not form in the crevice regions.
Conduct Crevice Flushina O. erations with Boric Acid: Prairie Island started crevice l
o flushing in 1986 using two days of time. Since then we have added boric acid to the crevice flushing procedure. The time has been reduced to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> since only l
a small amount of contaminants are being removed.
On-line addition of Boric Acid: Following the report of favorable laboratory results in 1986, Prairie Island began on-line addition of boric acid in unit 1 in March 1987.
The effectiveness of this remedial action remains controversial within the industry (EPRI IGA / SCC workshops in May 1991 and December 1992), improvements in the eddy current technology can make comparisons difficult, however, since a different set of tubes would have been identified for everyone if RPC inspections had been available and/or used in the past. Prairie Island will continue to use boric acid until such time as an inhibitor of equal or greater effectiveness is justified agt97u2. doc t
l l
1 March 5,1997 i
Page 9 for on-line use. One of the recommended boric acid practices, low power soaks, has not been implemented at Prairie Island.
Use of other chemical inhibitors: At the present time, NSP supports EPRI research for other chemical inhibitors. Our current evaluations centers around the use of titanium compounds to inhibit the growth of IGA / SCC. A titanium chelate, TYZOR l
LA Titanate has been added since January 1994.
Preventive sleeving: Sleeving is one method of reducing the probability of tube leak outages. The down side of preventive sleeving is the inability to follow the degradation mechanism and the reduction in the ability to examine tube support plate intersection above the sleeves. NSP has made the strategic decision to sleeve on an as-needed barm,, to insure that we are able to best follow the tube support plate problems and t a reduce our overall cost of steam generator repair and maintenance.
F* Reoair Criteria: The F-Star Alternate Repair Criteria allows tube to remain in service with indications below the F* distance. Additional Roll Expansion adds a new F* distance to the steam generator tubing and allows additional tubes to remain in service which have degradation in the lower tubesheet crevice region.
Detailed insoection Plans: Although not a recommendation for remedial actions, but rather a current inspection guideline,100% of the full length of all tubes in service are routinely examined at Prairie Island. This was started in 1982. In addition, all tubes with indications which can not be quantified, such as UDl's, DSI's, MBM's (in the tubesheet) are examined with the rotating coil probe due to its higher sensitivity. Repair decisions, in those cases, are based on the RPC results.
