22164 (12/95) h PURPOSE:
The purpose of this document is to provide a brief description of a technique which can be used to size Intergranular Attack (IGA) indications in Once Through Steam Generators (OTSG's).
BACKGROUND:
There have been several attempts to qualify a sizing technique for IGA. The Appendix H document for sg IGA detection in 0.750" and 0.875" tubing contains a plot for bobbin coil estimated depth versus truth.
gj This data in Figure I shows an Root Mean Square Error (RMSE) of 29 % and a correlation coeflicient of gy 0.23. Crystal River also evaluated sizing for a different data set as shown in Figure 2 with an RMSE of 27 % and a correlation coeflicient of 0.25. Both of these cases fall short of the 25 % RMSE sizing limit ga a specified in Appendix H.
k 8I PROJECT APPROACH:
A project was defined to work on improving the RMSE ofIGA sizing. The starting point for this work ng was the collection of data on all OTSG pulled tubes containing IGA defects with destructive examination lg (DE) results. The data was first reviewed to confirm the correlation of the eddy current (EC) indications with the correct DE location and result. Although some problems were identified, a high confidence
=l
! correlation was established to link the EC calls with the correct DE flaws.
After establishing the correlation of non destmetive examination (NDE) indications to DE results, the ll accuracy of the EC percent through wall (% TW) calls was reviewed. It was found that the original field calls, excluding signal to noise (S/N) calls, had a fair RMSE (22.6%) when used by themselves, but there ls
- ? were not enough of these calls (13) to establish a good statistical sample. The main problem with this d
%E situation is that the indications which were originally dispositioned as S/N now have to be sized. When conventional phase based eddy current sizing estimates are forced on the original S/N indications, the RMSE of the sizing becomes unacceptable.

1 REGRESSION CONCEPT:
! The regression concept is based on the premise that multiple types of measurements taken on an indication will contain more information than just a single measuremem. For example, if one can measure the peak to peak voltage and associated phase angles on three different frequencies, this additional data g may allow a more accurate sizing. There is an obvious physical reasoning that different frequencies with different skin depths and fields of view should provide some information about defect depth. However, glj
- the actual relationship is very difficult to determine without regression techniques due to interaction of ;
g
- ug the measurements.
Ej sg A multiple regression technique will mathematically calculate the relationships between multiple measurements (independent variables) and the actual defect depth by DE (dependant variable). Although
, ga ag it may be difficult to explain the relationship, it has become obvious that the use of two independent '
h n!
variables on the complete data set can produce a sizing estimate with an RMSE < 25 %. The use of a single input measurement cannot produce an RMSE below 25 %.
il i
Q JUSTIFICATION FOR REGRESSION:
E5 As discussed above, the use of two or more measurements has shown to provide enough additional gi "l information to provide a distinct improvement on both the RMSE and on the correlation coefficient.
- 3 The multiple frequency eddy current mix algorithm used for analysis of code examination data is based on hl B a multiple parameter regression solution. In the case of a mix, the independent variables are the vertical and horizontal components of each frequency chosen for the mix. For a repression mix, the dependant
", ll je variable is 'O'. Ideally, we want to have the coefficients of the mix produce a 'O' residual signal. The
. ideal solution is not practical, but the best fit solution is valuable. In the case of enhancing a signal, we l
seek the coeflicients which will produce the output signal which is a copy of the signal to be enhanced.
8, e
l I Thus a multiple regression mix algorithm is routinely used to produce a signal which is measured and
- used to predict code examination depth estimates.
[ls i
l lf The IGA sizing effort uses the same type of mathematical solution for multiple input variables to obtain the best prediction of a known depth.

I NNN7tmlw I+.vemide S - .y poco o, : s N 1/+ $"m'*C9m DATA REANALYSIS:
The original field data from the pulled tubes containing IGA defects was reanalyzed using a standard analysis guideline shown in Figure 3. Initially, there was no basis for selection of the measurements which should be used as input to the regression. Multiple measurements of phase angles, voltages and N depth estimates we-re made using peak to peak, max rate and vert max measurement modes for each gl frequency available. The reanalysis was done consistently between pulled tubes to provide more accurate g[ input data for the regression.
sW PULLED TUBE DATA:
G SE p Appendix A (8 pages)is a spreadsheet which lists the specific OTSG IGA pulled tube defects which have DE results along with the plant, date and original NDE result. Only the indications detected by bobbin og coil ECT were reanalyzed. In several cases of the Crystal River data, it was necessary to separate some lu cI of the DE flaws which had been reponed as a grouping into separate eddy current detections. The reanalysis of the data reported multiple indications within a grouping of DE flaws. A review of the data g showed that the real DE positions corresponded well with the reanalysis call positions.
%ltAll of the available DE and reanalysis information for detected indications was combined into a single
- j spreadsheet file to allow multiple parameter regression evaluation. A copy of this spreadsheet is itg contained in Appendix B (20 pages), )
l lwlBy 8 performing a linear multiple regression on the data with the tiue depth as the dependant variable, I li l coeflicients are calculated for each independent input variable. Similar measurements on unknown d defects are then combined with the calculated coeflicients to provide a ' trained' estimate of the unknown l
[J depth.

- ll. (j ACQUISITION
l The data acquisition would be the same as in the past, with differential data acquired on 200,400 and 600 KHZ frequencies with a 510 HF probe. The calibration standard will have to contain the four 20 %
FBH's for a normalization reference. The regression includes data acquired with a range of probe sizes i
$ from 0.500" to 0.510". The regression also includes data from medium frequency (MF) and high gl frequency (HF) probes.
H eg ANALYSIS SETUP:
lg The analysis setup would be to set the 100 % TW hole to 40 degrees as normal. The voltage normalization can be consistent with current analysis guidelines as long as a correction factor is used for ga the regression analysis. When normalized, the normalization must be stored to other channels. l f Specifically, if the 600 khz is used to normalize, that normalization factor should be stored to the 400 and ;i g*$
a 200 khz differential channels. l Il, g Analysis must measure the response of the 20 % flat bottom hole (FBH) after normalization. The gg regression was based on this value being set to 4 V on the 400 Khz differential channel. If a different ,
g8 normalization is used, then all voltage measurements must be multiplied by a factor which will correct the l 400 Khz differential peak to peak voltage on the four 20 % FBH's to 4 V. This correction factor must be applied before the voltages are entered in the regression calculations. For example, if the official 3g ge normalization is set for 6 V on the 4100% holes for 600 Khz diff, and the 20 % FBH measure at 5 volts on the 400 KHZ with this normalization, then all voltage readings (or coefficients) should be multiplied Bl
(( by 0.8 (4/5) before applying the regression formula. '
i ls GE ANALYSIS PARAMETERS:
8I i
$! Testing today has concentrated on evaluating regressions with a single measuremen technique on the ll WI three channels of differential data (600,400 and 200 khz). The max rate, peak to peak and vert max measurement modes were evaluated. There was no clear difference so the peak to peak mode was ih chosen for the best cases. Limiting the regression to a single measurement technique does degrade the i performance of the regression slightly and we are continuing to review other formulas. Multiple oy measurements and the use of absolute data or motorized rotating pancake coil (MRPC) measurements should improve the accuracy. The current regression requires the following measurements which could l g!8 be made by a single call on each of 3 frequencies:
7I 200 KHZ peak to peak phase peak to peak voltage
's 400 KHZ peak to peak phase peak to peak voltage g peak to peak voltage 600 KHZ peak to peak phase g

REGRESSION VARIABLES:
A single phase angle or depth measure seems to work well above 60 % true depth and would be acceptable if such indications could remain in service. However, below that true depth, a combination of measurements is necessary to allow any degree of accuracy in the estimated depth. By taking a combination of these variables measured on a number of pulled tube defects, coefficients can be I$
y calculated which allow a better estimate of actual max depth.
lI sg The variables are designated as follows:
If yg 200 KHZ peak to peak phase - D200PPP peak to peak voltage - D200PPV ,
400 KHZ peak to peak phase - D400PPP peak to peak voltage - D400PPV ga ag 600 KHZ peak to peak phase - D600PPP peak to peak voltage - D600PPV I h aS The three voltages must be multiplied by a correction factor of(4 / p-p voltage of four 20 % FBH @ 400 Khz) before continuing with the regression calculations.
Da Some modified values are calculated from these values to improve the regression model:

e REGRESSION PERFORMANCE:
The regression was trained on all available OTSG pulled tube DE and EC data points. Laboratory grown
{
og IGA, such as the Babcock and Wilcox Owner's Group (BWOG) tube integrity samples, was not used.
lg Their EC voltage responses were very high compared to the pulled tube data, and significantly degraded l g the model response. Although the RMSE may have still been acceptable, it was found that the model j performance was worse on the lower amplitude signals which are more characteristic of actual OTSG f IGA data. ,
i g!
l The RMSE is 8.5 and the correlation coefficient is 0.81 which indicates a good fit. Figure 4 is a tabulation of the regression data. Figure 5 is a plot of the regression results. The technique sheets are contained on pages i
g/ 21 through 24.

l'6 During development of the regression formula, several tests were performed using different input vaiables.
l[8 Below is a discussion of these tests.
Il USE OF 600 KHZ DEPTH CALLS ONLY eg I
s The use of the 600 Khz depth calls only produces a reasonable accuracy for calls above 60 % TW h true depth. This is the reason that the field analysis calls (without S/N and NQI calls) had a reasonable RMSE. However, for defects smaller than 60 % true depth, the depth calls based on a e phase calibration curve range from 0 to 95 %.

s .
22164 (12/95)
If the actual 600 Khz depth calls are compared to the actual defect depths, the correlation coeflicient is 0.05 for the tube pull data set. If the uninterpolated 600 Khz phase angles are compared to the actual defect depths, the correlation coeflicient is 0.03. Both of these tests indicate that the 600 Khz phase angle provides a poor measure of real IGA depth for defects below 60 %.
$ ELIMINATION OF 200 KHZ INPUT FROM REGRESSION:
Several tests were conducted to determine if the 200 Khz input could be eliminated from the ag regression. The tests are tabulated below with the correlation coefficient, standard error (related to gj RMSE) and the number of significant input variables.

TESTING OF NORMALIZATION CORRECTION FACTOR:
The regression tool was developed to allow a different normalization setup to be adjusted for use with the regression. The regression development was based on setting the 4 - 20 % TW FBH to 4 volts on the 400 Khz channel. This was done since some of the older tube pull data did not have 4 - 100% TW holes for
$ normalization. Current practice requires normalization references other than that used for the regression gl development.
p ag The calibration setup was performed with a second set of 100 % TW holes w. to 6 volts on the 600 KHZ channel. The 4 - 20 % FBH response was measured on 400 Khz to be 4.44 volts P - P. The correction gj 4 / 4.44 = 0.9 was entered into the regression tool setup to correct for the different
[g factor of a normalization method. The results of the test are shown in the table below:

22164 (12/95) h E BLIND TEST OF REGRESSION SIZING:
Due to an oversight, two DE locations in tube 109 - 30 were omitted from the regression development training and testing. The DE results were not included in charts with the other tube pull results and it was not obvious that the data had been omitted until the oversight was discovered during a subsequent review. It
$ was decided that this tube would be a good candidate for a blind test of the regression tool since it has not been previously analyzed as part of the IGA sizing task.
g
$g a Three measurements were performed on the two DE locations. The first measurement was performed with yj the original regression values which contained some training information from Oconee. The second analysis y was done with the regression parameters developed without the Oconee data. The third test was performed p
a by an analyst who had never used the regression tool and had no prior knowledge of the DE result. The results of this test are tabulated below:

}nl PROBABILITY OF DETECTION:
Il As part of the supporting documentation for this project, the FOD for IGA detection by bobbin coil in an
.E OTSG was evaluated. The results of the POD evaluation are documented in FTI drawing 1260216 A. The
!I POD for bobbin coil detection ofIGA in an OTSG for a defect depth of 40 % TW or greater is 0.838 with a 4

CONCLUSION:
The method described is one technique which can size IGA indications in OTSG's. The regression equation was chosen to minimize the analysis time required to make the multiple calls. Alternative measurements could provide a more accurate depth estimate at the cost ofincreased analysis time. The single bobbin coil i input was chose to minimize acquisition time. Preliminary testing has shown that additional MRPC length, width and amplitude information can provide substantialimprovements to the accuracy of predicted depth.
08 gg This method should be used to size IGA defects during future OTSG inspections. The accuracy of this gj method should be tested with all future OTSG DE IGA flaws. This method should be refined as desired as jg future information becomes available.
