ATTACHMENT 1 Response to Request for Supplemental Information NRC Reauest The NRC staff has reviewed your application and concluded that additional information addressing the derivation of the instrument setpoint values associated with the loss of voltage relay setpoint is necessary to enable the staff to make an independent assessment regarding the acceptability of the proposed amendment/relief request in terms of regulatory requirements and the protection of public health and safety and the environment. The submittal should include information on all instrument uncertainty factors used to derive setpoints.

Response of Reference 1 provided design analysis QDC-6700-E-0939, "Loss of Voltage Relay Setpoint for Buses 13-1, 14-1, 23-1, and 24-1," which establishes the new loss of voltage relay setpoint, setting tolerances, expanded tolerances, and allowable values based on the new analytical limits. During a conference call with the NRC on November 3, 2016, the NRC clarified that additional justification was needed related to the methodology and acceptance criteria listed as Items 2.3, 2.4, and 2.5 on page 5 of design analysis QDC-6700-E-0939, which are listed below.

2.3 Vendor Specifications Published instrument vendor specifications are considered to be based on sufficiently large samples so that the probability and confidence level meets the 26 criteria, unless stated otherwise by the vendor.

2.4 Negligible Uncertainties Per Appendix I of NES-EIC-20.04 (Ref. 5.1 .2), the effects of radiation (eR), humidity (eH), power supply (eV), calibration standard equipment (STD), and seismic (eS) under normal operating conditions may typically be considered negligible. For the evaluation of normal operating conditions, these errors are considered negligible unless otherwise noted.

2.5 Other Environmental Effects For environmental effects not considered negligible (Section 2.4), if the vendor does not provide a separate specification but the environmental limits are bounded by the vendor operating limits, then the effect is considered included in the reference accuracy.

Calculation QDC-6700-1-0848, Revision 0, "Instrument Drift Analysis of General Electric Model 121AV69A1A Voltage Relays for 4.16kV Emergency Bus (Loss of Voltage)," as referenced in design analysis QDC-6700-E-0939, Section 4.6 "Calculated Drift Specifications," validates the 26 drift for a 24 month surveillance interval (i.e., 30 months with late factor). Calculation QDC-6700-1-0848, Attachment A, documents seven years of raw data (i.e., 1993 through 1999) from surveillances of the voltage relays. Calculation QDC-6700-1-0848 is provided in .

ATTACHMENT 1 Response to Request for Supplemental Information In addition, Exelon Generation Company, LLC (EGC) procedure ER-AA-520, "Instrument Performance Trending," requires periodic updates of the drift analysis. The most recent periodic update was documented in EC 394927, "Prepare a Drift Analysis Per ER-AA-520 (2013)," which further validated the 2a drift with 11 years of empirical data from 2002 through 2013. 3 of EC 394927, which addresses the calculation QDC-6700-1-0848 drift analysis, is provided in Attachment 3.

Section 6.2 of design analysis QDC-6700-E-0939 provides justification for the random errors for the Loss of Voltage relay. The justification for negligible uncertainties is provided in Section 2.0, "Negligible Uncertainties," and Table 11, "Negligible Errors and Uncertainties for Relays and Timers," of Appendix I to NES-EIC-20.04, "Analysis of Instrument Channel Setpoint Error and Instrument Loop Accuracy." Appendix I to NES-EIC-20.04 is provided in Attachment 4.

NES-EIC-20.04 defines an acceptable method for establishing the uncertainties associated with instruments, instrument loops, and instrument setpoints and for applying these uncertainties in the determination of instrument loop accuracy, allowable values, and calculated setpoints at several EGC nuclear stations. The NRC has approved use of this methodology for Quad Cities Nuclear Power Station (QCNPS) as discussed below.

In Reference 2, the NRC issued license amendments for QCNPS, Units 1 and 2, to support the conversion of the QCNPS Technical Specifications to a set of improved Technical Specifications based on NUREG-1433, Revision 1, "Standard Technical Specifications, General Electric Plants BWR/4." The Technical Specifications changes included increases to surveillance frequencies to support the transition to 24-month fuel cycles. The associated NRC safety evaluation documents the NRC's review of Revisions 1 (ADAMS Accession No. ML003698624) and 2 (ADAMS Accession No. ML003721342) of NES-EIC-20.04. In addition, as stated in the NRC's safety evaluation, EGC also provided Revision 3 of NES-EIC-20.04 to the NRC. In the safety evaluation, the NRC concluded that "The staff also finds that the instrument setpoint methodology used by the licensee to determine the allowable values is acceptable."

Subsequent to the issuance of the Reference 2 license amendments and associated safety evaluation, EGC issued Revisions 4, 5, and 6 to NES-EIC-20.04. None of these revisions impacted Appendix I to NES-EIC-20.04. Therefore, the methodology for treatment of negligible uncertainties used in determining the loss of voltage relay settings is the same methodology reviewed by the NRC in 2001.

1.0 PURPOSE I OBJECTIVE 1.1 in order to support a new 24-month operating cycle, the base calibration interval for the instrumentation addressed by this calculation needs to be increased from 18 to 24 months. The purpose of this calculation is to establish the drift uncertainty values and characteristics that will be used by instrument uncertainty calculations for determination of setpoints and allowable values for the subject instrumentation. The drift values will be determined for a maximum surveillance interval of 30 months, because of the extra 25%

grace period allowed by Technical Specifications. (24 Months x 1.25 = 30 Months)

I 1.2 Specifically, this calculation addresses the voltage function of General Electric Model 121AV69A1A Voltage Relays, with tag numbers as shown in Table 1.2-1 below. Also shown in the table are the calibration procedure numbers and functions, associated uncertainty calculations, and applicable Tech Spec sections.

A summarized description of the methodology is listed under this section, but the detailed references for criteria, equations, and values used are detailed in Section 6 and within the attachments.

2.2 The methodology of analyzing As Found / As Left drift data is made up of several general steps. The steps for the analysis are listed herein, but are explained more fully in References 5.1.2 and 5.1.3. The mathematical computations of the statistical analysis are performed within an EXCEL spreadsheet. All data within the spreadsheet are printed out in the form of the Attachments to this calculation.

2.2.1 As Found and As Left data from historical calibration records are entered into a spreadsheet, from which drift uncertainty is derived. The date of calibration is also recorded.

2.2.2 Drift uncertainty for each calibration point is computed by subtracting the As Left data of one calibration from the As Found data of the next calibration. Time between calibrations is computed from the calibration dates.

2.3 Initial T-tests for outliers are performed to identify potential invalid or inappropriate data for the analysis. The data identified as outliers are researched to determine if the data should be excluded from the rest of the analysis. A small portion of outliers may be excluded from the analysis based on being purely statistical outliers in accordance with Appendix J to Reference 5.1.2.

2.4 In order to characterize the drift uncertainty, normality and time dependency are analyzed through a series of steps.

2.5 The drift data is checked through standard statistical means for determination of the normality of the data set. The Chi-Square Goodness of Fit test or either the W or D Prime test is used, depending on sample size. if these approaches do not confirm that the data is normally distributed, then visual examinations are used with a normality plot and coverage analysis to determine if a normal distribution is conservative with respect to the data. The coverage analysis consists of a histogram and a bin-by-bin comparison of actual data to expectations for a normal distribution. If the data cannot be determined to be normally distributed, or conservatively treated as normal, the drift is considered as a systematic (bias) error in the instrument uncertainty calculations.

Finally, regression analyses are also performed for the mean and standard deviations of the bins that were selected for use in the binning analyses, if a sufficient number of bins are selected.

2.7 A drift tolerance interval, to be used for instrument uncertainty analysis, is determined, based on the results of the tests above. The drift data is characterized as normal or systematic, or as part bias and part random, or random.

2.8 Acceptance Criteria: Since the conclusion of the calculation will be to generate a value and description of the characteristics of the drift of the device, there are no acceptance criteria.

STATION/UNIT: (quad Cities/1 and 2 NEP-12-02.01 Effective Date: 11/4/99 Page 9 of 13 CALCULATION NO: QDC-6700-1-0848 REV. 0 6.1.2 After the statistical outlier test described in section 6.2.1 below and removal of any outliers, a pooling test was performed as described in Sections 2.3.1.4 through 2.3.1.6 of Appendix J to Reference 5.1.2 and as directed in Reference 5.1.4. A critical T-test was performed, with the Critical T value reduced incrementally until 10% of the data population were outliers, to determine if proper pooling techniques were used. The critical T value had to be reduced significantly to show significant additional outliers.

Outliers appeared across the data set, without any evident correlation to improper pooling of the data. Therefore, it is concluded that the data within the initial data set is from the same statistical pool, and therefore has been combined properly for analysis.

6.1.3 Attachment B is a listing of the As Found and As Left data from available historical plant calibration records. Note that the calibration dates are also recorded, and notes are provided to clarify the activities performed. This data was entered into an EXCEL spreadsheet for computation of the drift values, time intervals between calibrations and the statistical analysis of the data.

6.1.4 Drift uncertainty is computed by subtracting the As Left data of one calibration from the As Found data of the next calibration, as documented in Attachment C. Attachment C also shows the computation of the time intervals between calibrations.

6.2 Determination of Outliers 6.2.1 The outlier analysis is recorded in Attachment D to this calculation. One outlier was removed from the data set. One outlier represents 3.125% of the initial data set. Since this is less than 5% of the initial data set allowed per the guidelines of Reference 5.1.2, this outlier was removed from the analysis. The critical T values for various sample sizes are tabulated in Attachment E.

6.3 Tests for Normality 5.3.1 The Chi-Square Goodness of Fit test was performed on the data to test for normality.

Since the result of the Chi-Square computation, 15.135, is greater than the degrees of freedom, 9, the Chi-Square test cannot confirm normality of the data. (See Appendix C, Section CA of Reference 5.1.3 for methodology.) The results of this test are tabulated in Attachment F.

6.3.2 Since the final data set consists of 31 data points, the W Test was performed on the data, per the requirements of Reference 5.1.3. The W Test confirms that the data is a sample from a normal distribution. A summary of the results of the test is included in Attachment G.

STATION/UNIT: Quad Cities/1 and 2 NEP-12-02.01 Effective Date: 11/4199 Page 10 of 13 CALCULATION NO: QDC-6700-1-0848 REV. 0 6.3.3 For Information Only, a normality plot and histogram are included in this analysis. The Normality Plot for this data is displayed in Attachment H. The function displayed by the Normality Plot is not a linear function however, one cannot fully confirm normality with this plot alone.

6.3.4 For the coverage analysis, a histogram shows the distribution of points in the actual drift data versus that which would be observed if the data ideally conformed to the normal curve. To generate the histogram data, the drift values are categorized into 12 bins, in relation to the mean and standard deviation. In addition, expected numbers of data points are calculated, assuming that the data was a normal distribution and that the data set was exactly representative of a normal curve. The histogram is documented in Attachment 1.

6.3.5 By visual inspection, the following items are noted. Although the data does not tend to reasonably follow a linear model as shown in the normality plot, the data is relatively close to a normal distribution as shown in the histogram, so the data is near normal.

From looking at the histogram and bins within Attachment I, the data appears to generally resemble a normal distribution with a larger than normal concentration of data around the mean, which is supported by a moderate kurtosis. The data does have adequate population within t 2 standard deviations to provide the required coverage for normality. Therefore, the histogram and normality plot provide additional visual evidence of normality of this data set, as confirmed by the W Test in Attachment G.

6.4 Time Dependency 6.4.1 In order to determine time dependency of the drift data, the data is first plotted as a scatter plot in Attachment J. The trendline within this scatter plot shows a slight decreasing trend from a small initial positive value to a small negative value, but no specific conclusions can be made from the scatter plot alone.

6A.2 To continue on with time dependency analysis, the binning analysis is performed. The data is divided into bins, based on the intervals between calibrations as defined in section 2.5.2.1 of Appendix J to Reference 5.1.2. Statistical summaries for each bin, including count, mean, standard deviation, and mean time interval are computed. This information is given in Attachment K to this calculation.

6.4.3 Per section 2.5.2.3 of Appendix J to Reference 5.1.2, after removing those bins with 5 or less data points and those with 10% or less of the total population, the remaining bins are 3, 4 and 6. A T-test was not performed between any bins being considered, because the bin count difference between bins is less than 20% of the total data count.

The valid interval, as defined by Section 2.6.1.4 of Appendix J of Reference 5.1.2, for the binning regressions is from bin 3 through bin 6, or 136 to 800 days.

STATION/UNIT: Quad Cities/1 and 2 NEP-12-02.01 Effective Date: 11/4/99 Page 1 it of 13 CALCULATION NO: QDC-6700-1-0848 REV. 0 6.4.4 Attachment K shows a plot of the mean and standard deviations of the drift data versus the average time interval between calibrations for the subject bins. It also provides all of the binning parameters and statistics that are a part of the binning analysis. The plot reveals that the mean of the drift data exhibits a non-linear function by varying up and down over the analyzed period, starting at a negative value in bin 3, going to a positive value in bin 4, and returning to a negative value in bin 6. The standard deviation of the drift data does increase over the analyzed period.

6.4.5 Per section 2.5.2.4 of Appendix J of Reference 5.1.2, a drift regression analysis was performed on the drift data that was Included in the selected bins above and the data in between them. In this case, 100% of the drift data was included because no data is contained in bins 1, 2, 7 and 8. The regression analysis included as Attachment L displays an R Squared value is much less than 0.3, thereby exhibiting no linear time dependency of the mean. An additional regression analysis was performed on the absolute value of the drift data, and is included as Attachment M. The regression analysis for the absolute value of the drift data displays an increasing trend, but the R Squared value for the absolute value is much less than 0.3, indicating no linear time dependency.

6.4.6 The scatter, binning analysis and drift regression plots all indicate a slightly sloping mean value over time, which crosses zero towards the end of the analysis. Because of these plots, and since the R-Squared value within Attachment L is much less than 0.3, the mean will be conservatively treated as time independent per the criteria of Section 2.5.2.6 of Appendix J to Reference 5.1.2.

6.4.7 Although the regression analyses showed no particular linear time dependency per the R Squared value in Attachment M, visual assessments of the data in the scatter plot, the binning plot and absolute value regression plot indicate that the standard deviation of the data tends to increase over time. Since the most conservative treatment of drift is linear (Reference 5.1.7, Section 6.2.7), the standard deviation of the drift is conservatively treated as linearly time dependent in this analysis.

6.5 Drift Tolerance Interval and Characterization 6.5.1 This analysis of drift for General Electric Model 121AV69A1A Voltage Relays confirms that the random portion of the drift is normally distributed (Section 6.3.2), but the analysis also identified increasing random drift over time (Section 6.4.7). The calculation also determined the drift bias term to be time independent per Section 6.4.6 above.

STATION/UNIT: Quad Cities/1 and 2 NEP-12-02.01 Effective Date: 11/4/99 Page 12 of 13 CALCULATION NO: QDC-6700-1-0848 REV. 0 6.5.2 The drift bias term for time independent drift is determined from the mean of the final data set, per Section 2.6.1.1 of Appendix J to Reference 5.1.2. The mean of the final data set is computed in Attachment D to be +0.035 volts. This value equates to 0.042 percent of full scale when using 83.7 volts (the lowest voltage setpoint value of the relays covered by this calculation per Attachment A) as full scale. Per the guidelines established in Section 2.6.1.1 of Appendix J to Reference 5.1.2, this value can be considered negligible. Therefore, a drift bias term will not be considered in this calculation.

6.5.3 The random portion of the drift is determined by linearly extrapolating the standard deviation of the data to the required calibration interval of 915 days. This is done in Attachment N by extrapolating the standard deviation line from bins 3, 4, and 6. The standard deviation line of those bins is extrapolated to 915 days by using the regression "intercept" and "X variable 1" coefficients listed in the ANOVA Table on Attachment N.

To determine the random portion of the drift, per section 2.6.1.3 of Appendix J of Reference 5.1.2, the extrapolated standard deviation value is multiplied by a confidence multiplier (2.549) for 95/95 for 30 data points (the total within the subject bins). The 95/95 confidence factor multiplier is selected because the instruments under analysis provide an ECCS protection function. The confidence multiplier comes from tables in Reference 5.1.4, which are copied from Reference 5.1.5.

Random Drift Tolerance Interval (95/95% Bound) =:t KS where: K o 2.549 (Confidence Multiplier for 30 data points) (Ref. 5.1.4)

S e 0.741 volts (Extrapolated Standard Deviation Attachment N)

Random Drift Tolerance Int. (95/95% Bound) = t (2.549)(0.741)

= +/- 1.889 volts (915 Days) 7.0

SUMMARY

AND CONCLUSIONS 7.1 The bounding 915 day drift value for the voltage function of the General Electric Model 121AV69A1A Voltage Relays (See Table 1.2-1), has been determined to be a random

+/-1.889 volts, with a negligible bias value. The random portion of the drift term is confirmed as normally distributed, and should be treated as a 2a value for uncertainty analysis. The random portion of drift is conservatively treated as linearly time dependent.

7.2 The results of this calculation can be conservatively applied to the voltage function of any General Electric Model 121AV69A1A Voltage Relay which meets the criteria listed in Section 5.3, "Considerations When Combining Instruments Into a Single Group", of Reference 5.1.3.

1. Data is divided between 12 bins, based on the mean and standard deviation values.

(See Attachment I.)

2. Probabilities are listed for each bin, based on Normal Distribution. Cumulative Probabilities are listed to verify that a total of 1.000 Is obtained from the total probabilities from the segments (These two columns were derived from Table B*2 of Reference 5.1.3.)

3. The Expected Frequency (Fa) is determined by multiplying the Normal Probabilities, Pnorm, by the Number of Drift Data Points (N), or -count, which comes from Attachment D

4. The observed frequency is the number of actual drift data points which fie within the bins as defined above. This can be easily observed from the data within Attachment 1.

5_ The Chi - Square Statistic is computed by summing the terms on the right of the table:

Per Section C.1.1 of Reference 5.1.3, X2 = Sum[(Oi-Ei)2/Ei]

6.

Conclusion:

Since the result of the Chi-Square computation ,15.135, Is greater than the degrees of freedom, 9, per Section C.1.3 of Reference 5.1.3. the Chi-Square cannot confirm the assumption of normality for this data set. See Attachment I.

1. Order the drift data from Attachment D In ascending order in the first column.

2. Obtain mean, standard deviation, and sample size from Attachment D.

3. Establishing bins In 1/2 sigma increments from the mean to 2.5 sigma in both directions, derive the upper bin limits, in units of drift, based on the values of the mean and standard deviation.

4. Obtain expected frequency for a normal distribution in each bin from Attachment F.

5. Manually compute the number of observed drift data points within each bin, and list under observed frequency.

6. Plot the Expected Frequency and the Observed Frequency Data on the Histogram to compare.

7. Compute the total number of observed drift values within +/-0.5, 1.0, 1.5, 2.0, and 2.5 sigma bounds, based on the observed frequencies recorded earlier.

a. Compute the percentages of the observed drift values within the bounds idenfied, as compared to the total sample size.

9. if necessary and appropriate. adjust the standard deviation to provide the appropriate coverage.

Results: The data displays a moderate kurtosis, and appears to be near normal. The initial analysis showed that the observed data population within the +/- 2 sigma value contained the required population for a normal distribution. This analysis provides additional visual evidence of the normality of the data set which is confirmed in the W-Test (Attachment O) of this calculation.

1.0 INTRODUCTION

The errors and uncertainties listed in this appendix have historically been found to be negligible under nonnal operating conditions. if the individual preparing an instrument loop accuracy calculation determines that the specific conditions apply, then these errors and uncertainties do not have to be evaluated in the calculation.

2.0 NEGLIGIBLE UNCERTAINTIES 2.1 Radiation Effects The effects of normal radiation are small and accounted for in the periodic calibration process. Outside of containment there is not a creditable increase in radiation during normal operation. The uncertainty introduced by radiation effects on components is considered to be negligible.

If an as-fOLind/as-left analysis has been performed based on historical calibration data, then normal radiation effects are considered to be included in the drift analysis results.

2.2 Humidity Effects The uncertainty introduced by humidity effects during normal conditions is not typically addressed in vendor literature. Therefore humidity effects are considered to be negligible unless the manufacturer specifically mentions humidity effects in the applicable technical manual. The effects of changes in humidity on the components are considered to be calibrated out on a periodic basis. A condensing environment is regarded as an abnormal event that will require maintenance to the equipment. Humidity's below 10% are expected to occur very infrequently and are not considered.

If an as-found!as-left analysis has been performed based on historical calibration data, the humidity effect is assumed to be included in the drift analysis results.

2.3 Power Supply Effects It is expected that regulated instrument power supplies have been designed to function within manufacturer's required voltage limits. The variations of voltage and frequency are expected to be small and the power supply voltage and frequency uncertainties are considered to be negligible with respect to other error terms.

If an as-foundlas-left analysis has been performed based on historical calibration data, the power supply voltage and frequency effects are assumed to be included in the drift analysis results.

Revision 6 NES-EIC-20.04 2.4 Calibration Standard Error (STD)

The calibration standards used by the station to maintain and calibrate station M&TE are expected to be maintained to manufacturer's specifications. These calibration standards are more accurate than the station M&TE by a ratio greater than 4:1. Therefore, the effects of the calibration standard error are considered to be negligible with respect to other error terms.

2.5 Seismic/Vibration Effects The impact of Seismic Effects in the setpoint calculation should be consistent with the Licensing Design Basis of the specific station (e.g. assuming a design Seismic Event coincident with a Design Basis Accident).

For normal errors, seismic events less than or equal to an OBE are considered to cause no permanent shift in the input/output relationship of the device. For seismic events greater than an OBE, it should be verified that the affected instrumentation is recalibrated prior to any subsequent accident to negate any permanent shift, which may result from a post seismic shift.

Unlike Seismic effects, Vibration effects may not always be calibrated out or included in the statistical drift. Consideration must be made of the "normal operating" versus "calibration" conditions. If the relative vibration conditions of these two states are not the same, then the vibration effect must be considered. This effect is not calibrated out or included in the historical calibrations data.

If an as-found/as-left analysis has been performed based on historical calibration data, the vibration effect is considered to be included in the drift analysis results, if the normal operation conditions and the calibration conditions are similar.

2.6 Lead Wire Effects Since the resistance of a wire is equal to the resistivity times the length divided by the cross sectional area, the very small differences in the length of wires between components does not contribute any significant resistance differences between wires. Therefore, the effect of lead wire resistance differences is considered negligible, except for RTD's and thermocouples.

If a system design requires that lead wire effects be considered as a component of uncertainty, that requirement must be included in the design basis. It is assumed that the general design standard is to eliminate lead wire effects as a concern in both equipment design and installation. Failure to do so is a design fault that should be corrected.

The lead wire effects for RTD's and thermocouples must be considered separately and must be evaluated for each specific application.
