. Renewal Of Steam Generator Tube Interim Plugging Criteria for Unit 1 Cycle 9 -

]l Gentlemen:

.l The purpose of this letter is to follow up to the recent phone conversation' between Duke' l

Power Co. and the NRC concerning the use of a 0.630 inch diameter bobbin probe (630 y

~

probe) at Catawba Unit 1.

1 The 630 probe had been utilized on past inspections at Catawba Unit 1 in the cold leg. The l

purpose of this inspection had been to enhance detection of free span cracks. The 0.610 inch diameter bobbin probe (610 probe) had been previously utilized for the inspection of the U-j bends and hot legs. In order to minimize inspection time and enhance the inspection, Catawba L Unit 1 utilized the 630 probe to inspect the tube full length during the acent refueling outage.

'An evaluation was performed to understand the differences between the probes. A sununary j

and preliminary results am included in attachment I as Duke Power committed to in our phone conservation on March 8,1995.

i

[

The preliminary results of the evaluation indicate mom variation between the probes'than j

expected. This variation is probably due to analyst variability and not associated with the i

probes.. While the data is further evaluated to determine the source of the error, conservative i

adjustments have been made with respect to our plugging criterion at Catawba Unit. I to' 1

account for the error.

Nuclear Regulatory Commission March 13,1995 Page 2 Catawba is committing to the following Steam Generator Tube Plugging criteria which presides for the conservative adjustments necessary:

Flaw indications with a bobbin coil voltage less than or equal to 1.0 volt or 0.8 volt for tubes inspected by a 0.630 inch probe can remain in service without further action. For flaw indications in excess of 1.0 volt or 0.8 volt for tubes inspected by a 0.630 inch probe but less than 2.7 volts or 2.2 volts for tubes inspected by a 0.630 inch probe, the tube can remain in service provided an RPC inspection of the indication does not detect ODSCC or any other degradation mode. Crack indications above 2.7 volts or 2.2 volts for tubes inspected by a 0.630 inch probe, will be plugged or repaired by sleeving, and do not require RPC confirmation.

In addition Catawba also commits to perfomiing a more detailed assessment of the evaluation which will be included in the 90 day report. An assessment 'he NDE error associated with the use of a 630 probe on the IPC will also be included in th(

/f report.

I Attachment A to this letter provides a comparison of 0.630 and 0.630 bobbin probes..

Attachment B is a table ofdata collected on Unit I with 3 graphs redundant to those prosided in Attachment A.

"stanha Unit I Comparison of 630 and 610 Bobbin Probes Il nckground i

The 0.630 inch diameter probe (630 probe) had been utilized on past inspections at Catawba Unit 1 in the cold leg. The purpose of this inspection had been to enhance detection of free span cracks. The 0.610 inch diameter probe (610 probe)had been previous?y stilized for the inspection of the U-bend and hot legs. In order to minimize inspection time and enhance the inspection, Catawba Unit I utilized the 0.630 inch diameter probe to inspect the tube full length. An evaluation was performed to quantify the ditTerences between the probes. The evaluation utilized ASME standard test data, McGuire Unit 2 test data and Catawba Unit I test data.

P 13y applying the use of a 0.630 bobbin coil probe for the inspection at Catawba Unit 1, it is our opinion that by so doing we could enhance the detection and sizing of di indications. The 0.630 inch bobbin probe has been used at our McGuire Nuclear Station because of its enhanced capability for detecting small free span indications. It was also apparent in our testing of TSP indications at the McGuire plant, that the 0.630 probe resulted in clearer signals (i.e. sharper transitions) for small indications. This thinking is supponed by several eddy current related rationale.

in our opinion, the use of a 0.630 probe will increase the fill factor or probe to tube coupling and therefore increase our sensitivity to degradation. Since the eddy currents are more densely populated near the coil windings and decrease with distance, it was our reasoning that improving our probe to tube coupling would accomplish our two objectives. The first objective would be to concentrate more of the eddy currents in closer proximity to the ID of the tube and subsequently increase the concentration of the eddy currents throughout the tube wall. The second reason was that by increasing the probe diameter, we could funher reduce the undesirable effects that probe motion or wobble, would have on any signals of degradation. Therefore, by implementing the use of a.630" probe, we would enhance our inspection by increasing our sensitivity to degradation while reducing the effects ofextrannous signals.

A resultant enhancement from ti e use of a 0.6F probe would be our increased ability to better size ODSCC indications By instituting the use of a 0.630 probe, increasing our sensitivity to indications and funher eliminating the influence of probe motion on these indications, we feel this would give us a more accurate representation of the tme voltage of the indication signal.

Attachment A Page 2 ASMlljtandard Test An ASr.

-.ndard was pulled 31 times with a 0.610 probe and a 0.630 probe. The data was normalized to 2.75 volts for the 4-20% through wall flat bottom holes on a 550/130 kilz differential mix (mi-1). The voltage of each ASME hole was then measured ofrofMix 1. It is our assessment that the probes perform essentially identically for the ASME standards. The average of the ratio of the 630 volts to the 610 volts is 1.01 with a standard deviation ofless than -

0.02. This trend was evident for each category of standard analyzed, hence it is likely that a real difTerence exists, but is not significant to the perfonmnce of the probes. See data in Attachment 1.

McGuire Data Test During the most recent McGuire Unit 2 refueling outage, a comparison was made of TSP indications which were run with a 610 and 630 probe. The preliminary results of the analysis are summarized below. The data is presented in Attachments 2-4.

On average the 610 probe voltage was 93% of the 630 probe voltage, with a standard deviation of 15%. Also on average the 610 volts were 0.05 Volts less than the 630 probe volts with a standard deviation of 0.08 Volts. The correlation of the 630 volts to the 610 volts had an index of determination of 91.1%. Hence, there is a relatively strong correlation of the 630 voltage to the 610 voltage.

The index of determination for the correlation of the ratio of the voltages to the 610 probe volts was 7%. For the correlation of the ratio to the 630 volts the index was 0.05%. Hence, it is likely that there is no correlation hetween the ratio of the probes volts to the absolute voltage.

The index of detennination of the correlation of the difference in probe voltages to the 610 probe voltage was 1.4% For the 630 probe voltages the index was 3.3%.11ence, the data did not indicate that the differences in probe voltages is correlated to the absolute volts of the indications.

This is most likely due to the small difference from unity in the voltage ratio, the small sample size, and the fact that the majority of the data is less than 0.8 volts.

Since the ratio of the volts is likely not correlated to the voltage it i3 reasonable to assume that a single ratio value can be established for cor;>erting the volts obtained from the 630 probe into equivalent values for the 610 proh t 110 wever, due to the limited amount of McGuire TSP indication data, additional data was acquired at Catawba Unit 1. We established a 90%

confidence bound on the ratio for applica ion at Catawba. The statistics would be based on a non-parametric evaluation. The plan for data collection, data analysis, and acceptance criteria are described below.

Data Analysis Each of the indications in the data samples, or oins were reinspected using new 610 and 630 bobbin coil probes. The results of the inspection were analyzed by independent eddy current analyst iraspection teams. The team using the 610 probe was independent and isolated from the team evaluating the results from the 630 probe. The resuhs of the reinspection / analysis were then i

categorized into analysis bins using the same limits as above for the source bins according to the voltage from the 610 probe. An additional bin, referred to as analysis bin 0, for indications with a 610 probe amplitude ofless than or equal to 0.59 volts was created. A comparison of the probes' results for each bin was then peiformed.

1 Discussion of Analysis Results In contrast to the results from the preliminary study, little correlation was evident between the probes in bin 0 through 2. A strong correlation was found between the probe voltages for bin 3.

}

Relative to the application ofIPC, bin 3 with 610 probe voltages greater than 1.0 volts is the most meaningtbl.

The final segregation of data resulted in a total of 83 data pairs iri bin 3. A comparison of the probe voltages is illustrated on Figure 1. The index of determination (the square of the correlation coeflicient) of the correlation of the 630 volts to the 610 volts was found to be 95.2 %. Hence the data indicated that the 630 probe volts are strongly correlated to the 610 probe volts. The average ratio of the 610 probe volts to the 630 probe volts was 1.13 with a standard deviation of 0.09. The average difference of the 610 voltage from the 630 probe volts was 0.16 volts with a standard deviation of 0.13 volts. The index of determination of the ratio of the probe readings, i

see figure 2, to the voltage was found to be 3.2%. The index of determination of the difference in i

the probe readings, see figure 3, to the 610 voltage was found to be 35.6 %. As expected fiom early cons;deration and previous experience the ratio of the readings is likely independent of the probe voltage. While the difference in readings may appear to exhibit a low correlation, the opposite is the case. The correlation coefficient is 0.60. This coeflicient is significant at a greater than 99.9% level for the data sample size (83). This is consistent with the ratio of the probe amplitudes exhibiting no correlation ie., for a constant ratio of volts the difference in voltage readings must increase with voltage.

In summary, neither criterion 1)nor criterion 2) as delineated above are met Hence the 90%

confidence limit on the ratio of the 610 probe voltage to the 630 probe voltage should be applied to the 630 probe amplitude to determire the voltage level to trigger inspection of an indication using RPC.

Attachment A PaEtl Catawk Data Collection Approximately two hundred (200) hot leg tube support plate indications have been acquired for the purpose of comparing the 630 probe to the 610 probe. The elements of the data collected consisted ofcollating sample data as follows:

1)

A random sample of fifty (50) indications with 630 amplitudes in the voltage range of 0.60 to 0.79 volts (referred to as source bin 1).

2)

A random sample of fifty (50) indications with a 630 amplitudes in the voltage range of 0.80 to 0.99 volts (referred to as source bin 2).

3)

All ODSCC indications greater than or equal 1.00 volts as measured by the 630 probe (referred to as source bin 3).

Catawba Data Acceptance Criteria The criterion developed for the use of the 630 probe field data were delineated as follows:

1)

If the mean difference between the probes was 0.05 volts with a standard deviation ofless than or equal to 10 %, the 630 probe data would be used directly for Interim Plugging Criterion (IPC) purposes.

2)

If the ratio of the 610 to 630 volts was less than 1.1 at a 90% confidence level, with an attendant small standard desiation, the volts obtained from the 630 probe would be adjusted by the average ratio adjusted to a 90 % confidence level.

3)

If neither of the previous criterion are met, the 630 voltages would be adjusted by the ratio of the probes output at a 90% confidence level, and all indications with adjusted voltages greater than 1.0 volts would be inspected by a rotating pancake coil (RPC) probe. This is the same as reducing the 630 criterion for perfonning RPC We would plan to ratio the 630 probe voltages by a constant if the 610 to 630 ratio is less than 1,1 at a 90% confidence limit if the standard deviation on the ratio is small (approximately less than or equal to 5%). The ratio limit is small to prevent unnecessarily plugging indications due to the 90% confidence limit. If neither of these criteria are satisfied, we would plan to inspect all 630 probe indications with a voltage greater than the 1.0 volt repair limit divided by the ratio at 90% confidence limits.

Attachment A Page 5 Determination ofRepair criterion The distribution of the ratio of the probe amplitudes is illustrated on Figure 4. Based on non-l parametric statistics, the 90% confidence bound for a 95 % portion of population is given by the j

Sist ordered value. This actually gives a lower 92% confidence on the ratio of the 630 probe volts to the 610 probe volts of 0.8. Since the IPC is based on a 610 bobbin coil probe voltage of i

greater than 1.0 volts as a trigger to perform a RPC inspection of the indication, the appropriate trigger using the 630 bobbin coil probe is 0.8 volt. Relative to the Catawba Unit 1 IPC, RPC confumation of bobbin indications of greater than 0.8 volts implies confirmation ofindications greater than 1.0 volts had a 610 probe been used. In addition, since the ratio is' independent of amplitude, The 2.7 volt limit for repair of an indication regardless ofRPC confumation should be adjusted to 2.2 volts.
