PURPOSE The Main Steam Line high flow trip portion of the reactor isolation system detects-and isolates breaks in the large steam lines outside the reactor containment.

The Main Steam Line Differential Pressure Switches provide the high steam flow MSIV signal.The purpose of this calculation is to determine acceptable instrument settings for the main steam lines high flow instruments DPIS-2-116 to DPIS-2-119 A, B, C, & D. Instrument settings include the Nominal Trip Setpoint, the Allowable Value and ALT /AFT values. Calculation outputs will be used to verify the adequacy of current setpoints.

Revision 1 of this calculation takes into consideration the effects of extended power uprate (EPU) and the new Analytical Limit. This calculation was performed with a goal of retaining the current setpoint value of 143 psid (Reference 10.7). This is considered acceptable because the current setpoint remains conservative under EPU conditions.

2. METHODOLOGY This calculation is performed using the GE Setpoint Methodology as a guide as described in Appendix I to Engineering Standards Manual Section ESM-03.02, Revision 4, Design Requirements, Practices, & Topics (Instrumentation and Controls) (Reference 10.9). This methodology utilizes statistical estimates of the various instrument errors to achieve conservative, but reasonable, predictions of instrument channel uncertaintiesl The objective of the statistical approach to setpoint calculations is to achieve a workable compromise between the need to ensure instrument trips when appropriate, and the need to avoid spurious trips that may unnecessarily challenge safety systems or disrupt plant operation.

The determination of the differential pressure switch drift value used in this calculation is performed in accordance with ESM-03.02-APP-lli (Reference 10.14).3. ACCEPTANCE CRITERIA The setpoint and instrument settings should be such that the Analytical Limit will not be exceeded when all applicable instrumentation uncertainties are considered.

The existing setpoints and As-found/As-left ranges will be verified to provide sufficient margin using the GE methodology as a guide. A setpoint value will be established with a 95%/95% tolerance interval as a criteria of uncertainties (Reference 10.9). That, is, there is a 95% probability that the constructed limits contain 95% of the population of interest for an 18-month +25%calibration interval (Reference 10.18) for the pressure switches (aithoug~hthese devices are calibrated every 3 months). If the existing .setpoint and ranges do not provide sufficient margin, new setpoints or ranges will be specified by this calculation.

5. ASSUMPTIONS Validated Assumptions 5.1 M&TE reference accuracy were assumed to be 3 sigma values unless otherwise noted.5.2 No seismic data is available for the Barton switches.

Per Section 6.2.1.2, the ZPA of the C-126 the rack is 0.41g. Normal vibration effects are considered as part of the analyzed drift. Per Section 6. 1.1, seismic events are not considered as a service condition for the DPIS devices.6. ANALYSIS 6.1 Instrument Channel Arrangement 6.1.1 Loop Information:

DPIS-2-116 to DPIS-2-119 A, B, C & D are used during a Main Steam Line Break to close the MSIVs due to high steam flow. The flow in each of four steam lines is monitored by 4 DPIS switches across each of the flow elements.

In the event of a Main Steam Line Break, the element restricts the flow to 200% of the original rated mass flow or less. This rate is the design safety limit. A one out of two twicehigh flow signal in any one steam line will result in isolating all four Main Steam Lines.These instruments are required to function immediately upon a Main Steam Line Break and are not required to maintain setpoint accuracy during long term post accident conditions.

As such, long term, harsh environment effects are not applicable in this calculation.

The Barton Model 278 DPIS devices are Mercury type switches.

As such, seismic events have a significant impact on the performance of the devices. Per Reference 10.13, seismic events are not considered as a service condition for the DPIS devices. As such, seismic events, are not applicable in this calculation.

Vendor does not provide temperature effect values. Per Section 6.2.1.2, the maximum environmental temperature of 173 OF is bounded by the operating range of the device. Additionally, the vendor states thatthe devices contain a temperature compensator, which automatically protect the unit from zero and-calibration drift when the instrument is subjected to a change in ambient temperature.

Therefore, temperature effects are considered to be included in the vendor accuracy term.Note 3: The switch has been selected to operate within the Main Steam Line maximum pressure of 1200 psi as specified per Section 6.2.1.2. Therefore, Overpressure Effects are not applicable.

Note4: Per Reference 10.16, the SPE for a Barton Model 288A is 0.25 % FS per 1000 psi. Per Calculation CA-98-011 (Reference 10.17) the only significant difference between Model 278 and 288A is the use of a mercury switch vs. a snapping action switch. As such, the static pressure effect for a BartonModel 288A is applicable tothe MSL High Flow DPIS devices as well. Per Section 6.2.1.2, the maximum -line pressure is-1200 psi.

MONTICELLO NUCLEAR GENERATING PLANT CA-95-075 TITLE: Main Steam Line High Flow Setpoint Revision 1 Page 6 of 15 Effects of static pressure, not accounted for during calibration, are considered bias values. It is not known whether effects of static pressure will impact the DPIS devices in the positive or the negative direction.

As such, SPE is considered a (+/-)bias value and will be applied to both sides of the process outside of the SRSS.[(+ 0.0025) * (1200 psi /1000 psid)] = + 0.3 % FS+ 0.3 % FS

Per Reference 10.8, switch model 278 is housed inside of a Weather-Proof casing.Environmental humidity has no effect on the devices.Note 6: The switches are mechanical devices and therefore power supply and EMI/RFI effects are not applicable in this calculation, Based on environmental conditions (Section 6.2.1.3 Note 2), the accuracy under Normal Conditions (AiN) is the same as Accuracy Under Trip Conditions (AiT).Accuracy under Long Term Post Accident Conditions (Aip) is not required.Ai = SRSS of random terms + bias terms This loop consists of one device, therefore:

MONTICELLO NUCLEAR GENERATING PLANT CA-95-075 TITLE: Main Steam Line High Flow Setpoint Revision 1 Page 7 of 15 The existing As-Left Tolerance specified on the calibration worksheet is +/- 4.5 psid.This tolerance value is unacceptable because it is considered excessive-and will"mask" instrument performance degradation.

The calculated ALT value of +/- 0.44 psid is also considered unacceptable because previous instrument performance suggests that this value is not routinely achievable and therefore impractical.

Therefore, it is suggested that the ALT be revised to +/-1.0 psi. This value will prevent "masking'" instrument performance degradation and is routinely achievable per Attachment 2.6.2.1.6 Device Calibration Error (C)Value Sigma Reference Calibration Tool Error C: 0.25 psi 3 4.6, Note 1 Tool Calibration Error CiSTD: 0.125 psi 3 4.7, Note 2 As Left Tolerance ALT: 1.0 psi 2 6.2.1.5 Note 1: Per Input 4.5, the differential pressure switches are calibrated with XPI-9021 (Ashcroft 2089).

Per the purchase specification, Reference 10.11, the accuracy of the steam flow restrictors is to be within +/- 2% of original rated flow. Per Reference 10.1, the 2% error is valid at 140% of original rated flow. The existing setpoint of 143 psid is within this flow rate. Therefore, the 2% error is taken as the PEA value for this calculation.

Per Reference 10.5, since the effect of the PEA value cannot be predicted at a particular future instant, it is considered a random value; and is thus eligible for SRSS combination.

Therefore:

PEA = + 2% of flow (random term).PMA: Per Reference 10.1, Section 3.13.5, the actual differential pressure signal from -the flow element is proportional to the specific volume of the steam. At pressures higher than the design pressure, process measurement accuracy (PMA) error exists.Per Reference 10.1, Section 3.13.5, a PMA allowance of 2% rated flow is utilized for determining the Main Steam Line High Flow Setpoint.

Although Reference 10.1 does not specify whether or not this effect should be applied as a random or bias value, the PMA causes a known effect on the instrument loop and should be applied as a bias term. For simplicity purposes, the PMA value is considered a (+/-) bias value and will be applied to both sides of the process outside of the SRSS. Errors due to pressures lower than the design pressure will create an early (conservative) trip and are not evaluated in this calculationl Therefore:

PMA = + 2% of flow (bias term).The values of PEA and PMA specified above are given in units of flow. In order to combine these effects with other loop uncertainty values, PEA and PMA must be.converted to units of differential pressure at the flow rate of inteiest.

This calculation uses the existing trip setpoint flow rate as the flow rate of interest.

Converting from DP to Flow is done using the general Flow D OP relationship:

Flow = K * (DP)1 2 or DP = (Flow / K)2 Per Input 4.3: 140% of existing flow = 147.7 psid MONTICELLO NUCLEAR GENERATING PLANT CA-95-075 TITLE: Main Steam Line High Flow Setpoint Revision 1 Page 9 of 15 Per Input 4.1: Rated flow 7.259 *106 lb/hr existing Rated flow 8.335 *10 6 lb/hr after EPU Solving for K using the existing flow rate of 7.259*106 lb/hr: (1.40)*7.259*106

/((147.7)1/2)

= 836208 This is the collective K value for all four steam lines. To get the K value for an individual steam venturi, the value is divided by four.Individual K value = 836208 / 4 = 209052 Using the above equation to determine the flow rate at 143 psid (existing setpoint):

Flow143 psid = 209052 * (143)1/2 Flow @143 psid = 2.4999

• 10 6 lb/hr.Therefore, a 2% flow error (PEA and PMA) is calculated as follows: Flow @2% error = 1.02 * (2.4999

• 106 lb/hr.Converting to differential pressure: D P@2% error = (2.5499

Per Reference 10.15, the flow limiters have an effective discharge coefficient of 0.97 compared to a predicted value of 1.0. This is equivalent to an error in differential pressure of 2.5 psid. This unpredicted variance of -0.03 has an additional effect on the accuracy of the flow element (PEA) determined in Section 6.3.Per Reference 10.12, the change is flow coefficient for EPU conditions is negligible.

MONTICELLO NUCLEAR GENERATING PLANT CA-95-075 TITLE: Main Steam Line High Flow Setpoint Revision 1 Page 10 of 15 Since the Coefficient of Discharge is directly related to the accuracy of the flow element, this effect is considered a component of PEA and thus a random value; eligible for SRSS combination.

6.5 Calculation

of Allowable Value and Operating Setpoint 6.5.1 Allowable Value (AV): Per Reference 10.2, the Analytical Limit (AL) is 140% of original rated flow. This value was chosen by GE to provide a margin above the original operational limit.The new AL will be taken as 165 psi (approximately 158% of original rated flow).This is an acceptable value as it is low enough to trip during a break of any main steam line. The AL is well below the Design Safety Limit of 200% of original rated flow and choke flow of the venturis.

It is also high enough above the operational limit to avoid spurious trips due to transients and valve testing.This value is used along with the following terms to calculate the Allowable Value.Term Value Sigma Reference.

The purpose of the LER Avoidance Evaluation is to ensure that there is sufficient margin provided between the AV and the NTSP to reasonably avoid violation of the AV. For a single instrument channel a Z value of greater than 1:29 provides sufficient margin between the NTSP and the AV. Although this is a multi channel loop, a Z of 1.29 will be used for conservatism.

Therefore, NTSP 2 is calculated to provide a lower bound for the NTSP based on LER avoidance criteria.Sigma(L.ER)

The purpose of a Required Limits Evaluation is to ensure that the combination of errors present during calibration of each device in the channel is accounted for while allowing for the possibility that the devices may both be recalibration.

Since this loop contains only one device, an evaluation is not required.6.5.8 Spurious Trip Avoidance Evaluation:

The STA is evaluated against the edge of the As-Left Tolerance band ,for conservatism.

Refer to Reference 10.1 for more detail. Per Section 6.5.4, the operating setpoint is 143 psid. Per Section 6.2.1.5, the ALT is 1.0 psid. Therefore, (NTSP -ALT) = 143 psid -1 psid (NTSP -ALT) = 142 psid MONTICELLO NUCLEAR GENERATING PLANT CA-95-075 TITLE: Main Steam Line High Flow Setpoint Revision 1 Page 1-3 of 15 Sigma(STA)

The same operational limit will be used for EPU during Main Steam valve testing. The valve testing occurs at reduced power and therefore the existing operational limit of 121.54 psig is acceptable.

ZSTA = Adjusted NTSP -Operational Limitl.Sigma(STA) 1142-121.541 9.73 ZSTA =2.1.Therefore, the adjusted NTSP of 142 results in a ZsTAgreater than 1.65 and provides assurance that no spurious trips will occur.6.5.9 Elevation I Density Correction:

An elevation

/line correction is not required for the DPIS switches.

If a head pressure or process temperature does exist, a pressure or density change will be exerted on both sides of the switch equally dnd will have no noticeable effect on differential pressure detected by the switch. As such,. no significant error is introduced due to elevation or density changes.Reference 10.15 indicates that there may be a zero offset possibly caused by a water leg between the steamline tap and the condensing chamber..

This offset creates an indicated differential pressure larger than actual differential pressure.For.increasing setpoints, this effect is conservative because it results in an early trip.Task Report T2005 (Input 4.8) assessed.

the effect of increased moisture carryover on the main steam flow instrumentation at EPU conditions.

The increase in measured pressure drop with moisture increase was found to have-an insignificant influence on the main steam flow instrumentation.

TITLE: Main Steam Line High Flow Setpoint Revision 1 Drift Analysis Attachment 2 Page 1 of 7 A1.1 Data Grouping The following Barton model 278 differential pressure indicating switches are included in this analysis: Equipment ID DPiS-2-116A DPIS-2-116B DPIS-2-116C DPIS-2-116D DPIS-2-1 17A DPIS-2-117B DPIS-2-117C DPIS-2-117D DPIS-2-118A DPIS-2-118B DPIS-2-1 18C DPIS-2-118D DPIS-2-119A DPIS-2-119B DPIS-2-119C DPIS-2-119D Range 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid 0 -200 psid Setpoint (desired)143 psid 143 psid.143 psid 143 psid 143 psid 143 psid 143 psid 143 psid 143 psid 143 psid 143 psid 143 psid 143 psid 143 psid 143 psid 143 psid As shown in section 6.2.1.2, the devices are exposed to similar environmental conditions with the same calibration frequency.

Therefore, the individual drift data for the devices can be grouped without further numerical testing, following the criteria set forth in step.5.4.8 of ESM-03.02-APP-III (Input 12).A1.2 Populating the Spreadsheet Calibration data for the switches included the date of calibration, as well as the As-Found and As-Left setpoint values. This data was input into a Microsoft Excel spreadsheet, and included in Attachment 2.The calibration interval was determined by taking the difference between the current and previous calibration dates. Per step 5.3.9 of ESM-03.02-APP-111, the calibration interval was converted to months by dividing the number of days by 30.5 days per month.The Drift value was calculated by taking the difference between the current.calibration As-Found value and the previous calibration As-Left value.None of.the data points were removed from the final data set. Although the outlier test results showed several potential outliers, the points were kept in the analysis.

Per the instructions of Attachment 1 from Input 12, there were no valid reasons for removing the outliers.

MONTICELLO NUCLEAR GENERATING PLANT CA-95-075 TITLE: Main Steam Line High Flow Setpoint Revision 1 Drift Analysis Attachment 2 Page 2 of 7 A1.3 Spreadsheet Performance of Basic Statistics The following information was determined for each instrument individually:

The average or mean value (x) of the drift data for each instrument was determined by using the "Average" function in Microsoft Excel. This function uses the following equation: X-n where x = average of data set xi = individual drift value*n = total number of values The standard deviation of a data set returns the measure of how widely dispersed the values are in relation to the mean of the data. The standard deviation for each instrument was determined using the "STDEV" function.

Microsoft Excel uses the following equation in the "STDEV" function: n(n-1)where s = standard deviation of-sample xi= individual drift value n = total number of values The variance (S2) is another measure of data spread from the mean. The variance for each instrument was determined by using the "VAR" function in Microsoft Excel. The variance is calculated as follows: S2 __________

n(n -1)where S2 = variance of sample x= individual drift Value n = total number of values The largest positive drift value for each instrument was determined by using the "MAX" function.The largest negative drift value for each instrument was determined by using the "MIN" function.The number of data points (n) for each instrument was determined using the "COUNT" function.The psid values for average, standard deviation, and largest positive and negative-drift were converted to a percent of instrument span using the following formula: psid value% span s 100%psid span MONTICELLO NUCLEAR GENERATING PLANT CA-95-075 TITLE: Main Steam Line High Flow Setpoint Revision 1 Drift Analysis Attachment 2 Page 3 of 7 A Drift Trend Plot was developed for each instrument by plotting the drift value versus calibration date. Bounds corresponding to +/- 2s (2 standard deviations) are shown on the plot.Page 49 of Attachment 2 presents the combined drift data statistics for the subject units.The combined-statistics were determined using the preceding methods.A1.4 Outlier Detection and Expulsion Per step 5.5 of ESM-03.02-APP-III, the t-Test is used to detect the presence of outliers in the final data set. The t-Test requires the use of the following equation: x.-x S where t = individual t-Test statistic s = standard deviation of sample xi = individual drift value x = individual drift value The t-Test involves calculating the individual

't' statistic for each data point, and comparing them to a critical value. The critical value depends on the sample size, and is obtained from.Table 9.2 of Input 12.The t-Test is shown on pages 50 through 74 of Attachment

2. Based on a sample size of 1094, the critical value utilized in the t-Test is 4.0. Seven of the calculated individual t-Test statistics exceeded the critical value which, according to the t-Test, identifies them as outliers.

However, based on the criteria of Attachment 1 to ESM-03.02-APP-III, none of the seven points were eliminated from the final data set.A1.5 Normality Tests Most statistical analyses make the assumption that the values in question are normally distributed.

The criteria in Input 12 require that the data set be tested for normality.

It is recommended that forsamples of over 50 data points, the D' Test be utilized.D' (D-Prime)

Test The D' Test calculates a test statistic value for the sample population and compares the calculated value to the values for the D' percentage points of the distribution, which are tabulated in Table 9.7 of ESM-03.02-APP-III.

The D' Test is two-sided, which means that the two-sided percentage limits at the stated level of significance must bound the calculated D' value. For the given sample size, the calculated value of D' must lie with the two values provided in Table 9.7 in order to accept the hypothesis for normality.

To perform a D' Test, the drift value data set is sorted and numbered in ascending order from smallest to largest.

The following equation is used: T S Determine the critical D' values based on the sample size using Table 9.7 in Input 12. If the exact sample size is not listed in Table 9.7, interpolate the values to obtain an estimate of the critical D' values.Refer to pages 75 through 98 of Attachment 2 to see the D' Test for the drift data. For a sample size of 1094, the critical D' values are 9833.6 and 9959.7. The calculated D'value was 9551.5. Based on this result, the assumption of normality is rejected.Coverage Analysis Since the assumption of normality was rejected by the D' Test, a coverage analysis was performed per section 4.7.5.E of ESM-03.02-APP-III.

A coverage analysis is discussed for cases in which the hypothesis tests reject the assumption of normality, but the assumption of normality.

may still be a conservative representation of the data. The coverage analysis involves the use of a histogram of the data set, overlaid with the equivalent probability distribution curve for the normal distribution, based on the data sample's mean and standard deviation.

Visual examination of the plot is used, and the kurtosis is analyzed to determine if the distribution of the data is near normal. If the data is near normal, then a normal distribution model which adequately covers the set of drift data as observed is derived. This normal distribution will be used as the model for the drift of the device.Sample counting is used to determine an acceptable normal distribution.

The standard deviation of the group is computed.

The number of times the samples.are within 2 standard deviations of the mean is computed.

The count is divided by the total number of MONTICELLO NUCLEAR GENERATING PLANT CA-95-075 TITLE: Main Steam Line High Flow Setpoint Revision 1 Drift Analysis Attachment 2 Page 5 of 7 samples in the group to determine a percentage.

If the percentage of data within 2 standard, deviations of the mean is greater than 95.45%, the existing standard deviation is acceptable to be used for the encompassing normal distribution model. In case the percentage is less than required, the standard deviation should be enlarged.

The required multiplier for the standard deviation in order to provide this coverage is termed the Normality Adjustment Factor (NAF). If no adjustment is required, the NAF is equal to one.The coverage analysis is presented on page 99 of Attachment

2. Visual inspection shows a moderate kurtosis, as most of the data points are found within 1.5 standard deviations of the mean. Calculations using the table on page 99 of Attachment 2 show that 95.9% of the data is encompassed within 2 standard deviations of the mean. Therefore, it is concluded that a normal distribution is a conservative representation of the data, and thus NAF is equal to 1.A1.6 Selection of Final Data Set The devices in question are only calibrated to one setpoint.

Therefore, all data points will be utilized and no further analysis is required in determining the final data set.A1.7 Time-Dependency Analysis Standard statistical analyses do not consider time-dependency.

The following tests attempt to uncover any time-related performance and the impact of any time-dependency on the analysis.Drift Interval Plot A drift interval plot is an XY scatter plot that shows the data set plotted against the time interval between calibrations.

It relies on visual inspection to discriminate the plot for any trend in the data to exhibit a time dependency.

A prediction line can be added to this plot to aid in the analysis.Page 100 of Attachment 2 shows the drift interval plot for this data set. The plot shows a scatter of drift values, both positive and negative around the 1.5 and 3 month calibration intervals.

As these were the most common intervals, most of the data points are found near these two time periods. Based on the equation of the regression line, there may be a slight time-dependency present. The drift interval plot includes the tolerance interval (TI). This tolerance interval is equal to the random drift term calculated in section A1.9.Standard Deviations and Means at Different Calibration Intervals (Binning Analysis)The binning, analysis is the most recommended method of determining time dependent tendencies in a given sample pool. Following the instructions in step.4.8.3 of Input 12, the drift data was segregated into different groups (bins) corresponding to different ranges of calibration intervals.

In order for further analysis to be done, at least 2 valid bins must exist. In order to be considered valid, a bin must contain more than five data points and more than 10% of the total data count. The binning analysis (Attachment 2, pages 101-123) shows that only 1 valid bin exists. Therefore, per the criteria in .Input 12, the data will be established as moderately time dependent for the purposes of extrapolation of the drift value.Due to the fact that multiple valid bins did not exist in the binning analysis, no further time-dependency testing is available.

MONTICELLO NUCLEAR GENERATING PLANT CA-95-075 TITLE: Main Steam Line High Flow Setpoint Revision I Drift Analysis Attachment 2 Page 6 of 7 A1.8 Drift Bias Determination The absolute value of the average calculated drift for the trip units is 0.009 psid. Similarly, the absolute value of the average calculated drift is less than 0.1% of the calibrated span (200 psid). Based on the criteria of ESM-03.02-APP-III, it is concluded that the instrument drift does not have a bias. Therefore, the drift bias terms will be taken as 0 in this analysis.A1.9 Analyzed Drift Value Bias Term Basedon the section A1.8, the instruments do not have a bias. Therefore, the bias term will be equal to 0.Random Term -The random term of the analyzed drift value is calculated with the below equation: AD ,do= s x TIF x NAF where ADrandor = random term for analyzed drift s = drift standard deviation TIF = 95%/95% tolerance interval factor NAF = Normality Adjustment factor The value of TIF is obtained from Table 9.1 of ESM-03.02-APP-III.

Based on a sample size of 1094, TIF is equal to 1.960. From the coverage analysis, NAF was determined to be 1. From page 49 of Attachment 2, the standard deviation of the sample is 0.88. Thus the random term is equal to 1.73 psid.30-Month Predicted Drift.(Random Term)Since the drift was determined to be moderately time dependent, the following equation was used to extrapolate the drift uncertainty:

ADE. random = ADradom X CIE where ADE.random

= extended period drift term ADrandom = random term for analyzed drift CIE = extended calibration interval (surveillance interval +25%)ClO = average observed calibration time interval from bin with longest time interval The value of the random term for the analyzed drift was determined to be 1.73 psid. The extended calibration interval is equal to the surveillance calibration interval (3 months)plus an additional 25% (0.75 months). Therefore, ClE is equal to 3.75 months. CIO is MONTICELLO NUCLEAR GENERATING PLANT CA-95-075 TITLE: Main Steam Line High Flow Setpoint Revision 1 Drift Analysis Attachment 2 Page 7 of 7 determined from a valid bin of data with the longest calibration interval.

There was only one valid bin, with a calibration interval range of 1.25 to 3.75 months. The average calibration interval within this bin is equal to 2.8 months. These values produce a 30-month predicted drift term of 2.00 psid.Per the criteria in step 5.10.4.B, a check was made to ensure that the calculated 30-month predicted drift uncertainty is greater than the uncertainty calculated with the 99%/95% tolerance factor. Based on the large sample size ( > 1000 data points), the TIF for 99%/95% is equal to the TIF for 95%/95%. The uncertainty calculated using the 99%/95% TIF of 1.960 is 1.73 psid. -Therefore, the 30-month predicted drift uncertainty is 2.00 psid.

One of the requirements is that there are multiple valid bins. A bin is considered valid if it contains at least 5 data points and 10% of the total data. Only the middle bin (> 1.25 to 3.75) meets the criteria.

Therefore, the complete binning analysis cannot be performed on this data. Per the instruction in ESM-03.02-APP-Ill, the data is considered moderately time dependent.

For monitoring fow rates, they are used In cornunction with a primary element, such as an orifice in the line.These switches will wifthtand overranges equal to their rated safe workdng pressur They are offered In a wide range of differential and pressur ratings with either snap-ction mechanical contacts or magnetically operated mercury contacts in either a NEMA 4 waterIght oran exploiormroof cae.Actuation of these switches is either by a Barton, Model 109 or Model 224 Rupture-Prool Differential Pressure Unit. Accuracy.

stability of calibration, negligible static pressure shift and minimum maintenance are inherent features of these units.Switches are supplied with the Model 199 unit where mximunm sensitivi is required In the lower differential pressure ranges, where a field range change is anticipated or when a built-in pulsation dampener Is desired to control response time of the Instrument.

On the other haud, the Model 224 unit is employed to actuate the switch where the differentlal range specified exceeds that available with the 199 unit or where size and weight are prime consideution.

1. INTRODUCTION Between February 1 and February 24, 1972 the Monticello Nuder Power Station (MNPS) of the Northern States Power Company wat returned to power after an ixteanded outage. During this outage the main stearn'ina flow limiters, ventri tubes supplied by the Permutit Company, had been modified to remove aome manufacturing defects.These defects did .not affect the ability of the devices to limit maximum siteam flow to 200% of rated steam flow, but by degrading the measurable pressure differential did affect the ability of the devices to measure the steamline flow rate. This document, discusses the performance of the modified venturi tubes for flow measurements as determined from data recorded during the February 1 to February 24 startup. Differential pressure data recorded on Match 10 and 11 are also included.2.

SUMMARY

AND CONCLUSIONS The modified stamrine flow limiters installed in the Monticello Station reownd to steam flow, in a consistent manner that correlates well with the theoretically axpected performance.

Assuming no errors in measuring either differential pressure across the flow limiters or reactor feedwaser, the flow limiters have an effective discharge coefficient of 0.97 compared to a predicted value of 1,0. This is equivalent to an error in differential pressure of 2.5 peid 14%), or in total feedwater flow rate of 200,000 lb/h 13%1, or aome combination of both. It is recognized that rho reported feedwater flow rate may be law by 0-5% so 1.0% since the control rod drive water flow rate was not rsrded. Whether the measured discharge coefficient or the predicted discharge coafficisnt is correct is rot known at.s time. but the difference is not large enough for concern. This performane, satisfies all reasonable expectations for the equipment.

3. DISCUSSION

3.1 BACKGROUND

The Monticello Nuclear Power Station, owned anrd operated by the Northern States Power Company, is equipped with steemline flow restriCsors supplied by the Permutli Company. One function of these devices is to limit the maximum possible steam flow through each of the four steamlines to no more than 200% of the design steam-flow rate.A second function is to provide a measurement of the flow rate through each starnline.

During the startup testing of the station, September 8, 1970. to July 5, 1971, it was observed that the differential pressure measured at any steam-flow rate was approximately a factor of 3 less than the expected value supplied by the vendor, It was noted that while lewer than expected the measured differential pressure behaved in a repeatable manner end plotted parallel to the predicted Ap versus flow curve.Because of the differences between predicted and observed Ap versus flow performance for the Permutit flow restrictors an experimental program was undertaken by GE-APED at the San Jose facility to determine the cause of the dlfferences and how the flow restrictors could be modified to make them respond more nearly 04'originally designed.This program determined that the low differential pressure readings were caused by a from a high pressure region into the throat tap piazametar ling. This leakage path in no way affecte the abilit~y of the flow restrictor to limit the maximum steam-flow rate tb the intended value. A modification to the throat tap was defined which was expected to make the measured Ap versus flow rate cose to the predicted perfotmantc.

This experimental program is reported in detail in Relerence

TITLE: Main Steam Line High Flow Setpoint Attachment 7 Page 4 of 8 NED&- 0--44*i 3.2 DATA RECORDING The differential Pressure scrosa each steamline flow limitar at Monticello is measured by four Barton Differential Preaure Indicator Switches ldPISl. These are in addition to any GE/MAC sensors which are part of the feedwater control circuits.

Figure I is a schematic drawing of the installation.

The Barton dPIS are spanned to read 0-200 paid.The calibration, zero shift with-pressure, and hysteresis of the 16 Barton dPIS (4 on each of 4 steamlineej were checked before the station was returned to power and again during an interruption in die power increase for turbine repairs. All differential pressure readings discussed here are based upon these dPIS.The total steam flow rate from the reactor is determined by a mass balance drawn around the reactor pressure vessel. The only term in this mesa balance of significance is the reactor feedwater. (Control rod drive water flow is 0.5%to 1.0% of the value of the feedweetr flow.) The feedwater measurement instrumentation was calibrated during the outage when the steam norzlas were being modified.

The output of the feedwater nozzle differential pressure device is read by the process computer and converted numerically to feedwater flow rate. It is also read by station instrumentation end converted electrically to become the value of feedwater flow rate displayed in the control room.All vaiues of total steam flow race reported here are equivalent to the feedwater flow rate displayed in the control roomi with the exception of sew data recorded on 10 March and 11 March. 1972. when only the computer output was recorded.

M~en both were recorded the computer value for feedwaetar is up to 2% lower then the control room recorder value.The reported values of reactor pressure and electrical output are those recorded by station personnel using normal plant isrumentation.

3.3 DATA REDUCTION There are two physical effects which can not be measured directly but which directly affect the validity and usefulness of the results. One of these is the presence of a zero offset, possibly caused by a water tag between the seiamfine tzp and the condensing chambers or a temperature difference in the instrument lines between the condensing chambers and the instrument rack. The second i4 the steam flow rate mismatch between the steaslines caused by smail differences in line geometries.

The presence of a Zero offset can be checked by closing a single main steam isolation valve MSIVI when the reactor is operating near 50% power aad then recordisg the readings of all dPIS. This was done at Monticello and average offsets ware found for each line. These average offsets were used to correct the measured differential pressures in the calculations preeanted here. The zero offset values do change with time and are between 0.4 paid and 2.5 paid.The effect of the offset is to give a larger than actual differential pres indication.

The magnitude of the offset is small relative to the differential pressure values measured at significant flow races.The steam-flow mismatch can be estimated from calculations if these caiculations include in sufficient detail the ai-buieT steamline geometries.

A more sraighotforward method Is to apportion the steem flow between the steamline!

on the basis of the measured differential pressures.

The relative flow values should be accurate since all Ap instrumentation wes recalibrated using a common method, The second method is the one used to determine individual steansline flow rates.The complete data-reduction mietod used can be illustrated best using an actual set of plant dat, This is done in.Table 1. All the data recorded during this startup of the Monticello plant were reduced in this manner and are plotted on Figure 2, The data recorded on 10 March and 11 March were not used in finding the "'bes(-flsi' curve because the feetwater data were recorded only from the computer.It is of interest to compare Ahe observed after-modification differential pressure versus flow behavior with that which would be predicted using the ASI1E expression for flow of a compressible fluid through a venturi.

RESULTS The data recorded by Northern States Power Company personnel at Monticello and reduced as described in Section 3.3 are prorted in Figure 2 along with the beat "least squares" fit to the data. Also, thesm data were fit for each individual smtm-flow limiter. The complete sat of data were refit including only p versus flow data'for line flows greeter thaws 40%, 45%, and 50% of rated. The coefficients of these fit curves are listed in Table 2.Included in Table 2 Is the standard error of estimate, sometimes called the root-man-lsquare difference between the data points and the lit curve. The experimental data were compered with the curve calculated fat a nozzle discharge coefficient of unity. The standard error of for this comparison is shown in Table 2. The calculated curve of differential pressure does not plot as the sguare of the flow because of the changing pressure with changing flow and the accuracy of the calculations.

It is not known why the corrected experimental data do not behave as zhe square of the slow. Possible reasons include unaccounted-for pressure effects. feedwatar flow measurement errors, and small instrumentation errors. APl fitting of the experimental data Is based upon the assumption that the measured values are exactly correct. In this case the eective average nozzle discharge coefficient can be calculated To be .S7. Notse that this effective C -0.97 includes the effects of all memurement errors including those in the fwedwater flow rate. As can be seen from Figure 7 the feedwatrar flow rate can not be accurately confirmed by secsondery plant measurements Such as turbine-generator output. A difference of I psid (1.7% of the rated flow differential pressure) is to e -difference of 10,000 lb/h. 0.58% of the rated steam flow rate..4-MONTICELLO NUCLEAR GENERATING PLANT CA-95-075 TITLE: Main Steam Line High Flow Setpoint Attachment 7 1 Page 7 of 8.NEDO-0-644 TaDlA 2 FIT DATA All Lines A B a.All data 21.49 Power >40% 21.59 Power >46% 21.60 Power >50% 21.65 Single Lirns Power >46%Line 116 21,47 Line 117 21.70 Line 118 21.72 Lino 119 21.86 Theoretical Curve 20.32 C. 1.0 2,068 0.816 2.034 0.798 2.017 0.796 2.021 0,864 al.0 2.12 2.20 2.41 2.70 2.22 2.53 2.51 2.53 2.031 2.020 2-018 1.993 0,773 0.799 0.791 0.862 2.009 0.0783 a it the "standard error of the estimate" for the best fit curve CAp 1 (date) ?:Ap (cslc from fix))],I 01.0 is the "ssnderd error of the estimate" where the calýulated 4p 1 values are based upon an assumed venturi dischargo oefficienz of 1.0.The units of c are psid..5-
