2.0 INTRODUCTION

The ANO-1 Emergency Feedwater Initiation and Control (EFIC) System is an instrumentation system that monitors selected plant conditions and automatically Initiates the Emergency Feedwater (EFVV) System upon detection of abnormal conditions. The EFW System is required for the accident analysis of Loss of Feedwater for EFW Sizing (Ref. 5.6.16), Main Steam Une Break, Small Break LOCAs and Loss of All Unit AC Power (Ref. 5.6.14).

The SG level signals are corrected for process density changes relative to the calibration density values. As depicted in the block diagram (Figure 1), the inputs into the compensation module consist of a level signal and a pressure signal. Per Reference 5.6.10, these signals are combined using the equations below to produce the output signals that represent the compensated level signals.

1) vo= 1 + 23.91 (APL-2.5) -4 .O*pt wherevoistheoutputvoltagefedto PW- Pst the Bistables.
2) v0 = 18.150*(APL7 2.5) - 3.036 *pSt where vo is the output voltage for the PW - Pst Low Range Level Control.

In the equations above, APL is the level signal corresponding to the SG level transmitter signal prior to density compensation (volts)

Pw is the density of water corresponding to the SG pressure transmitter signal. The density values are stored In EPROM and are retrieved based on the pressure signal. (lb/tA`3) pat is the density of steam corresponding to the SG pressure transmitter signal. The density values are stored in EPROM and are retrieved based on the pressure signal. (lb/ftA3)

All errors are converted to units of volts for a consistent analysis throughout the EFIC System modules. The equations above are used to determine the expected output voltage and the output voltage with maximum errors Included. The output voltage with maximum errors is compared to the expected output voltage to determine the loop uncertainty. The resulting uncertainty Isthen combined with the manufacturers specifications for the EFIC System.

SG LOW LEVEL INITIATE The Low SG Level Initiate setpoint for EFIC determines the level at which emergency feedwater i(EFW) is initiated during Loss of Main Feedwater (LOFVV) events. The in-plant setpoint evaluated per z Reference 5.6.44 is 11.00 Inches above the lower tube sheet (5.00 inches above the lower tap). This cl setpoint will be evaluated with respect to the instrument uncertainty in the Conclusions Section.

SG LEVEL CONTROL This is a control level setpoint designed to be selected following Initiation of EFW if one or more reactor coolant pumps (RCPs) are providing forced circulation. The current setpoint, per References 5.6.22 and 5.6.23, is 31 Inches. This setpoint will be evaluated with respect to the instrument uncertainty In the Conclusions Section.

ANO-1 Calculation No. DRN 05-3577 Pg to of _83 Paage 174 of 302 80-D-1083C-01, Rev. 7 The statistical method of the Square Root of the Sum of Squares (SRSS) is used to determine the random error on a component level and for the loop. Non-random errors are combined via simple addition with the random error term to establish the total error.

This calculation is done with the guidelines set forth in the Instrument Loop Error Analysis and Setpoint Methodology Manual (Ref. 5.6,1).

All percentages are expressed in terms of span unless otherwise noted.

All terms are considered random error terms unless noted by a lower case ubw suffix to indicate a bias or non-random error term or Y suffix to indicate a total of bias and random terms.

ANO-1 Calculation No. DRN 05-3577 Pg. '1 of 63 Page 175 of 302 80-D-1083C-01, Rev. 7 5.3.0 ASSUMPTIONS AND GIVEN CONDITIONS 5.3.1 The minimum and maximum temperatures expected for the transmitter reference leg fluid, 7 during normal operation, are 1040F and 118'F, respectively. These values are conservative per Reference 5.6.43, Table 1, for Elev. 336'.

5.3.2 The maximum temperature expected for the transmitter reference leg fluid, during accident conditions, is 285'F. This value is found in Reference 5.6.2, Appendix A. For the calculation of the process measurement error, it is assumed that the reference leg fluid does not flash.

Therefore, the density is taken from Reference 6.3 for 2850 F and 54 psia (P SAT).

5.3.3 The operating pressure range is assumed to be limited by the pressure inputs from the pressure loops (Ref. 5.6.7). Therefore, the operating pressure range Is 0 to 1200 psig.

5.3.4 Per Reference 5.6.8, the static pressure zero and static pressure span errors are correctable during calibration. Per Attachment 5-1 and References 5:6.22 and 5.6.23, the transmitter is calibrated based on a static pressure of 900 psig. The minimum and maximum operating static pressures are 0 psig and 1200 psig, respectively.

Since the transmitters are corrected for a static pressure of 900 psig (Pcor), the static pressure uncertainties will be computed using the maximum deviation from 900 psig, or 900 psi (900 - 0 psig). In addition, to maximize the static pressure span error, the maximum reading of 100% will be used.

5.3.5 Per Reference 5.6.8, static pressure causes a systematic span shift of -0.75% of input per 1000 psi increase which is correctable by applying a correction factor during calibration. Per Attachment 1 and References 5.6.22 and 5.6.23, a correction factor is applied during calibration based on a static pressure of 900 psig. A bias error is introduced when the actual operating static pressure deviates from the calibration pressure of 900 psig. A negative bias occurs for a deviation above 900 psig and a positive bias occurs for a deviation below 900 psig. The deviations are based on the minimum and maximum operating pressures (0 psig and 1200 psig).

In addition, the maximum DP input (100%) is used in that it yields the maximum, i.e.

the most conservative, error.

5.3.6 Individual error terms less than 0.05%Span are considered negligible (Ref. 5.6.1).

Where a note to this effect has been provided, the error is not provided in the calculations. However, where error terms less than 0.05%Span exist In error analyses, they are used in calculations though the impact is negligible.

5.3.7 The measurement and test equipment (M&TE) used at ANO is controlled by a program to ensure traceability is maintained. In accordance with Reference 5.6.9, M&TE specified for use in calibration of instrumentation should have an accuracy at least two times that of the Instrument being calibrated unless authorized by responsible management. Unless otherwise noted, the Calibration Error Effect for all devices is based upon using M&TE which is twice as accurate as the devices being calibrated. The calibration uncertainty assumes there are calibration devices on the input and output of the device being calibrated.

ANO-1 Calculation No. DRN 05-3577 Pg g. of 63 Page 176 of 302 80-D-1083C-01, Rev. 7 5.3.8 For purposes of determining Temperature Effect (TE) for the differential pressure transmitter, a variation of 50'F is used. This assumes a calibration temperature of 60'F and an Abnormal Temperature of 11 0IF (Ref. 5.6.2). For accident conditions, a variation of 2250 F is used. This assumes the maximum temperature in an accident of 2850F (Ref. 5.6.2).

5.3.9 Unless otherwise noted, the line voltage is assumed to be 120 VAC with a variance of +/-10 VAC and the DC power supplies are assumed to have a variance of +/-10% rated voltage.

These variances are assumed to be conservative per Reference 5.6.1.

5.3.10 Per Reference 5.6.8, the Rosemount transmitter drift is 0.20%URL over a 30 month period. References 5.6.22 and 5.6.23 indicate that the transmitters are calibrated every 72 weeks or 18 months. Tech Specs (Ref. 5.6.11) allow a 25%

extension, making the calibration interval 22.5 months. Since the calibration interval is within the vendor supplied drift specification, the 0.20%URL will be used as a bounding drift error.

5.3.11 Per Reference 5.6.12, the normal error specifications for the transmitter, given by the vendor, are accurate to three sigma. All other specifications are two sigma values, therefore, the normal transmitter specifications will be multiplied by 2/3 to convert them to two sigma values before combining them with other two sigma values.

5.3.12 The power for the IN converters and the VA converters is supplied from the internal power supply in the Foxboro nest (Ref. 5.6.25 - 5.6.26). This +/- 15 VDC power supply is regulated to 0.2% output voltage change for a +/- 10% change from nominal line voltage (Ref. 5.6.13). Since the power supply line voltage remains within the 10% criteria (5.3.9) the power supply error will be limited to 0.2 %. The power supply is also affected by temperature and has an ambient temperature effect of 0.5% for a 45 *F change within 40 - 120 *F. Since the power supply temperature effect envelopes the Auxiliary Building temperature range (5.3.13) the power supply temperature effect will be limited to 0.5%. The two power supply error terms will be combined using the SRSS method, since the two terms are random and independent, to provide a total power supply error.

Power Supply Error = i [(0.2)2 + (0.5)2]112

= +/- 0.539 %

5.3.13 The maximum normal temperature extremes for the Auxiliary Building is listed as 60 to 105 "F (Ref. 5.6.2). This calculation will use 60 "F as the calibration temperature for the Foxboro components which are located in the Auxiliary Building in the Electrical Equipment Rooms.

5.3.14 The vendor for the IN converters, Foxboro, supplied a reference accuracy (RA) specification of +/-0.2% of span. Per References 5.6.22 and 5.6.23, the converters are calibrated to +/-0.5%Span.

Therefore, a setting tolerance (ST) of +/-0.3%Span will be added to RA to make the adjusted device tolerance (Dtol) +/-0.5%Span. The error calculation for the IN converters will use Dtol in lieu of RA.

5.3.15 The MTE used to calibrate the signal converters is much more accurate than one-half the accuracy of the devices being calibrated (Ref. 5.6.22 and 5.6.23). Therefore, in lieu of using RlA/2 for the MTE accuracy (5.3.7), the actual accuracy of the DMM (+/-0.125%) and DVM (+/-0.005%) will be used.

ANO-1 Calculation No. DRN 05-3577 Pg R of & Page 177 of 302 80-D-1083C-01, Rev. 7 5.3.16 The vendor for the W and V/I converters, Foxboro, did not supply a drift (DR) error specification. It is assumed that DR will not be worse than the reference accuracy 71 (RA) or device tolerance (Dtol) of the device, whichever is greater.

5.3.17 All Foxboro normal performance specifications are considered 3 sigma specifications (Ref. 5.6.17). Therefore, the data must be converted to 2 sigma before being combined with other 2 sigma data.

5.3.18 The vendor specifies that the 625-ohm input resistor is a precision resistor (Ref. 5.6.10).

Per Reference 5.6.24, the resistor tolerance is +/-0.01%. The maximum error will result from maximum input, or 20 mADC and is determined as follows:

(625 + (.01%

  • 625)] * .02 A = 12.501 volts The maximum voltage (without error) would be 12.5 volts. Therefore, the error in percent span is (12.501-12.5)/span*100%= 0.0125 %Span. The error will be considered negligible per Assumption 5.3.6.

5.3.19 Per Reference 5.6.19, the Control Room temperature is 750F with a temperature variance of +/-90 F for the Abnormal and Accident Conditions.

5.3.20 The vendor for the EFIC system did not provide any drift data for the components.

Given the reference accuracy of the combination of the EFIC compensation module and bistable is 0.539 %span per 5.3.25 below, a drift allowance of approximately half of RA or 0.250 % is considered reasonable. This drift allowance will be increased to 0.258 % span 1Z by increasing it by a factor of 31/30 to account for the former 30 day vs. 31 day test frequency presently required by Technical Specifications.

z 5.3.21 The vendor did not supply a temperature effect or power supply effect error specification for the EFIC modules. Based on the small deviations in both the Control Room temperature and the power supply voltage, and based on similar devices in the Control Room, it is assumed that these deviations will have a negligible effect on the loop error.

5.3.22 The MTE used to calibrate the EFIC Modules is much more accurate than one-half the accuracy of the devices being calibrated (Ref. 5.6.22 and 5.6.23). Therefore, in lieu of using RA/2 for the MTE accuracy (5.3.7), the actual accuracy of the MTE (+/-0.125%) will be used.

5.3.23 The radiation effect for the transmitters is given in Reference 5.6.35 as +/-1.0%URL for doses less than 1 MRad/ hr and a TID less than 5 MRads. Reference 5.6.36 gives a dose of 2.1 MRads over a 3 year period for a Small Break LOCA. Although the dose given in Reference 5.6.36 may not bound all SBLOCA cases, it is assumed that doses will remain lower than 5MRads.

5.3.24 Foxboro specifies a separate accuracy and repeatability error term for the V/I converter.

Therefore, this calculation will combine both the accuracy and the repeatability by SRSS and use the resultant as the overall Reference Accuracy (Ref. 5.6.1):

ANO-1 Calculation No. DRN 05-3577 Pg to of_5 Page 178 of 302 80-D-1 083C-01, Rev. 7 Accuracy (A) e + 0.50 %SPAN Repeatability (R) = +/- 0.10 %SPAN Reference Accuracy = +/- [A2+R2]1/2 RA = + 0.51 %SPAN 5.3.25 Per Reference 5.6.20, each component within the EFIC Compensation Module has an accuracy of 0.25%SPAN and the EFIC Bistable Module has an accuracy of 0.20%SPAN.

The SG Low Level Initiate Bistable loop uses four components in the Compensation Module along with the Bistable (Refs. 5.6.29 and 5.6.30). Therefore, the reference accuracy for SUI is assumed to be the SRSS of the accuracies for four Compensation Module components and the Bistable Module, or 0.539%SPAN.

5.3.26 Per Reference 5.6.20, each component within the EFIC Compensation Module has an accuracy of 0.25%SPAN and the EFIC Control Module 'has an accuracy of 0.35%SPAN.

The SG Low-Range Level Control loop uses five components in the Compensation Module along with the Control Module (Refs. 5.6.29 and 5.6.30). Therefore, the reference accuracy for FRL is assumed to be the SRSS of the accuracies for five Compensation Module components and the Control Module, or 0.660%SPAN.

5.3.27 The vendor did not supply the time response for the voltage-to-current converter. It is assumed that the time response for the voltage-to-current converter is not worse than the time response for the current-to-voltage converter. Therefore, a time response of 0.1 second is assumed for the converter.

15.3.28 The SG Low Level Initiate Bistable has a 9.900 second time delay (Ref. 5.6.44).-The DRN 05-3577 bistables are tested and assumed to be acceptable with a +/-0.5 second tolerance (Refs.

5.6.22 and 5.6.23). Therefore, the time response analysis will assume a 10.400 second delay.

5.3.29 The calibration procedures state that the Low SG Level Initiate Bistable is calibrated to 5 0.650%SPAN. This is slightly greater than the reference accuracy (RA) of 0.539% Span DRN listed in Section 5.4.4.2 and less than the former tolerance of 1.0% Span. Therefore, a 05-3577 setting tolerance (ST) will be added to the reference accuracy (RA) to obtain a device l tolerance (Dtol) of 0.650% SPAN.

7 5.3.30 Note that the SG Low-Range Level Control bistables evaluated in this section are not associated with any Allowable Values in the Technical Specifications (Ref. 5.6.11). The drift terms will be revised to account for the slight decrease in frequency of Channel Functional test requirements required per Technical Specifications, however no additional evaluation of the impact to Allowable Values Is required in section 5.5.

5.3.31 EFIC Initiates on a low level of 11 inches above the lower tube sheet or 5 Inches of calibrated Ispan (3.3 % span, rounded), this is equivalent to an uncompensated voltage level of DRN approximately 2.833 volts or 2.84 volts (rounded). This trip is credited for a Loss of Feedwater 05-3577 (LOFW) event which does not assume a main steam or main feedwater line break. For LOFW the actual SG pressure would be expected to remain the same or increase above normal operating pressure at the the time of trip intifiation. Table 5.4.4.15 shows that for the range of bistable voltages from 2.5 - 6.0 vdc and for pressures equal to or greater than 900 psia the abnormal low level initiate bistable uncertainty (ABN SUlot) Is bounded by

+2.62 /-2.54% Span.

The Steam Generator pressure signals for EFIC Channels A and B come from the following pressure transmitters:

PT-261 8A PT-261 8B PT-2667A PT-2667B The loop error analysis for the above pressure transmitter loops is calculated in Section 1.0. The following errors ("RI o" from Sect. 1.0) for the Reference, Abnormal and Accident conditions are the errors associated with the pressure signal that is input to the EFIC density compensation module:

REF PRSo = +/- REF Roo (from Sect. 1.0)

REF PRSo = +/- 0.99 %Span = +/- 11.9 psi [Sect. 1.0]

ACC PRSob = + 0.00 %Span = + 0.0 psi [Sect. 1.0]

ACC PRSob = 0.07 %Span = - 0.8 psi [Sect. 1.0]

Note: The errors are converted from %Span to units of psi since the density computation error (Sections 5.4.4 and 5.4.5) is based on variations from actual SG pressure.

The process measurement error (PME) for this closed level loop is caused by density changes in the reference leg fluid due to ambient temperature variations. Since the loop is pressure compensated (Ref. 5.6.10), the density changes due to system pressure variations do not cause a process measurement error.

As the reference leg fluid temperature varies from the temperature assumed during calibration, the density of the reference leg fluid changes, causing the transmitter to sense a different differential pressure than expected, thus causing a bias process measurement error. The error will be positive when the reference leg temperature is greater than that assumed during calibration, and negative when the reference leg temperature is less than that assumed during calibration.

The assumed calibration conditions are given as follows: [Att. 5-11 Span = 143.98 1H2O (span of transmitter)

Per Reference 5.6.10, the densities are stored in EPROM based on the ASME Steam Tables. Table 5.4.4.1 compares what the density is at the actual SG pressure with the density at the SG pressure with the uncertainty included.

This methodology conservatively assumes that no interpolation is performed.

Table 5.4.4.2 determines the minimum and maximum input voltages for the uncompensated level signal based upon the error associated with the level signal (Section 5.4.3).

Table 5.4.4.3 computes the expected output voltages without errors. The equation used for the expected output voltages (Section 5.2.0) is as follows:

vo = I+ 23.91 *(APL- 2.5) - 4 .-*pst where v0 is the output voltage fedI Pw - pst to the Bistables.

Tables 5.4.4.4, 5.4.4.5 and 5.4.4.6 compute the output error due to the error in the uncompensated level signal for the reference, abnormal and accident conditions, respectively.

The equation used is as follows:

VIo = 1 + 23.91 *[(APL+/-LVLo)-2.5)] - 4.0*pt - v, Pw - Pst Table 5.4.4.7 computes the output error due to the error in the pressure signal for the reference, abnormal and accident conditions. This error is minimal compared to other errors in the loop. Therefore, for simplicity, only the accident error is considered for the pressure signal. The equation used is as follows:

V2o = I + 23.91 *(APL-2.5) - 4 0*pst - vo with the densities based upon the PW -Pst pressure signal with error PRSo Tables 5.4.4.8 and 5.4.4.9 compute the bias output error based upon the bias error in the uncompensated level signal for the abnormal and accident conditions, respectively.

The equation used is as follows:

Vob = 1 + 23.91*[(APL+/-LVLob)-2.5)] - 4 .0*pt -v, Pw - Pst

Credit is only taken for the initiation of EFW using this setpoint under the conditions of normal reactor building environment. Therefore, the uncertainties for the Abnormal Condition will be used in setpoint evaluation. Per Reference 5.6.45, the process limit for SG Low Level Initiate is 6 inches above the lower tubesheet (LTS). Since this trip provides protection for a r- decreasing level, the bistable positive abnormal error terms will be used.

Note also that the Technical Specifications provide an Allowable Value of 9.34 inches (Ref. 5.6.11).

Note that the Total Loop Error, Test Error and Z the as-left bistable tolerance (see Dtol above) support the Technical Specification Allowable o Value (Ref. 5.6.11) of 9.34 inches.

SG Low-Range Level Control (LRL)

This setpoint is used when adequate subcooling margin exists (at least one RC pump is operating). Since any inventory in the generator will be adequate to remove core decay heat, the process limit should correspond to to the lower tap elevation, 6 inches above the LTS.

The low-range level setpoint is currently 31 inches above the LTS. Since this setpoint provides protection for a decreasing level, the bistable positive accident error terms will be used.

The present setpoint of 31 inches (above the LTS) is conservative with respect to this calculation.

2.0 INTRODUCTION

The ANO-1 Emergency Feedwater Initiation and Control (EFIC) System is an instrumentation system that monitors selected plant conditions and automatically Initiates the Emergency Feedwater (EFVV) System upon detection of abnormal conditions. The EFW System is required for the accident analysis of Loss of Feedwater for EFW Sizing (Ref. 6.6.36), Main Steam Line Break, Small Break LOCAs and Loss of All Unit AC Power (Ref. 6.6.14).

The SG level signals are corrected for process density changes relative to the calibration density values. As depicted in the block diagram (Figure 1), the inputs into the compensation module consist of a level signal and a pressure signal. Per Reference 6.6.10, these signals are combined using the equation below to produce the output signal that represents the compensated level signal.

vo= 1 + 23 .91*(APLr 2 .5) - 4.0*pts where vo is the output voltage fed to Pw - Pst the Bistables.

Inthe equation above, APL is the level signal corresponding to the SG level transmitter signal prior to density compensation (volts) pw Is the density of water corresponding to the SG pressure transmitter signal. The density values are stored in EPROM and are retrieved based on the pressure signal. (lb/ftA3) pat is the density of steam corresponding to the SG pressure transmitter signal. The density values are stored in EPROM and are retrieved based on the pressure signal. (lb/ftA3)

All errors are converted to units of volts for a consistent analysis throughout the EFIC System modules. The equation above is used to determine the expected output voltage and the output voltage with maximum errors included. The output voltage with maximum errors is compared to the expected output voltage to determine the loop uncertainty. The resulting uncertainty is then combined with the manufacturers specifications for the EFIC System.

SG LOW LEVEL INITIATE The Low SG Level Initiate setpoint for EFIC determines the level at which emergency feedwater i (EFW) is initiated during Loss of Main Feedwater (LOFVW) events. The in-plant setpoint evaluated per z E Reference 6.6.39 is 11.0 inches above the lower tube sheet (5.0 inches above the lower tap). This Qi setpoint will be evaluated with respect to the instrument uncertainty in the Conclusions Section.

The statistical method of the Square Root of the Sum of Squares (SRSS) is used to determine the random error on a component level and for the loop. Non-random errors are combined via simple addition with the random error term to establish the total error.

This calculation is done with the guidelines set forth in the Instrument Loop Error Analysis and Setpoint Methodology Manual (Ref. 6.6.1).

All percentages are expressed in terms of span unless otherwise noted.

All terms are considered random error terms unless noted by a lower case 'b" suffix to indicate a bias or non-random error term or t suffix to indicate a total of bias and random terms.

ANO-1 Calculation No. DRN 05-3577 Pg 44 of $3 Page 230 of 302 80-D-1 083C-01, Rev. 7 6.3.0 ASSUMPTIONS AND GIVEN CONDITIONS 6.3.1 The minimum and maximum temperatures expected for the transmitter reference leg fluid, 7 during normal operation, are 1040F and 11 8F, respectively. These values are conservative per Reference 6.6.38, Table 1 for elev. 336'.

6.3.2 The maximum temperature expected for the transmitter reference leg fluid, during accident cond itons, is285'F. This value is found in Reference 6.6.2, Appendix A. For the calculation of the process measurement error, it is assumed that the reference leg fluid does not flash. Therefore, the density istaken from Reference 6.6.3 for 285°F and 54 psia (PSAT).

6.3.3 The operating pressure range is assumed to be limited by the pressure inputs from the pressure loops (Ref. 6.6.7). Therefore, the operating pressure range is 0 to 1200 psig.

6.3.4 Per Reference 6.6.8, the static pressure zero and static pressure span errors are correctable during calibration. Per Attachment 6-1 and References 6.6.22 and 6.6.23, the transmitter is calibrated based on a static pressure of 900 psig. The minimum and maximum operating static pressures are 0 psig and 1200 psig, respectively.

Since the transmitters are corrected for a static pressure of 900 psig (Pcor), the static pressure uncertainties will be computed using the maximum deviation from 900 psig, or 900 psi (900 - 0 psig). In addition, to maximize the static pressure span error, the maximum reading of 100% will be used.

6.3.5 Per Reference 6.6.8, static pressure causes a systematic span shift of -0.75% of input per 1000 psi increase which is correctable by applying a correction factor during calibration. Per Attachment 1 and References 6.6.22 and 6.6.23, a correction factor is applied during calibration based on a static pressure of 900 psig. A bias error is introduced when the actual operating static pressure deviates from the calibration pressure of 900 psig. A negative bias occurs for a deviation above 900 psig and a positive bias occurs for a deviation below 900 psig. The deviations are based on the minimum and maximum operating pressures (0 psig and 1200 psig).

In addition, the maximum DP input (100%) is used in that it yields the maximum, i.e.

the most conservative, error.

6.3.6 Individual error terms less than 0.05%Span are considered negligible (Ref. 6.6.1).

Where a note to this effect has been provided, the error is not provided in the calculations. However, where error terms less than 0.05%Span exist in error analyses, they are used in calculations though the impact is negligible.

6.3.7 The measurement and test equipment (M&TE) used at ANO is controlled by a program to ensure traceability is maintained. In accordance with Reference 6.6.9, M&TE specified for use in calibration of instrumentation should have an accuracy at least two times that of the instrument being calibrated unless authorized by responsible management. Unless otherwise noted, the Calibration Error Effect for all devices is based upon using M&TE which is twice as accurate as the devices being calibrated. The calibration uncertainty assumes there are calibration devices on the input and output of the device being calibrated.

ANO-1 Calculation No. DRN 05-3577 Pg 60 of S3 Page 231 of 302 80-D-1083C-01, Rev. 7 6.3.8 For purposes of determining Temperature Effect (TE) for the differential pressure transmitter, a variation of 50'F is used. This assumes a calibration temperature of 60'F and an Abnormal Temperature of 11 0IF (Ref. 6.6.2). For accident conditions, a variation of 2250F is used. This assumes the maximum temperature in an accident of 2850 F (Ref. 6.6.2).

6.3.9 Unless otherwise noted, the line voltage is assumed to be 120 VAC with a variance of +/-10 VAC and the DC power supplies are assumed to have a variance of i10% rated voltage.

These variances are assumed to be conservative per Reference 6.6.1.

6.3.10 Per Reference 6.6.8, the Rosemount transmitter drift is 0.20%URL over a 30 month period. References 6.6.22 and 6.6.23 indicate that the transmitters are calibrated every 72 weeks or 18 months. Tech Specs (Ref. 6.6.11) allow a 25%

extension, making the calibration interval 22.5 months. Since the calibration interval is within the vendor supplied drift specification, the 0.20%URL will be used as a bounding drift error.

6.3.11 Per Reference 6.6.12, the normal error specifications for the transmitter, given by the vendor, are accurate to three sigma. All other specifications are two sigma values, therefore, the normal transmitter specifications will be multiplied by 2/3 to convert them to two sigma values before combining them with other two sigma values.

6.3.12 Per Reference 6.6.20, each component within the EFIC Compensation Module has an accuracy of 0.25%SPAN and the EFIC Bistable Module has an accuracy of 0.20%SPAN.

The SG Low Level Initiate Bistable loop uses four components in the Compensation Module along with the Bistable (Refs. 6.6.29 and 6.6.30). Therefore, the reference accuracy for SUI is assumed to be the SRSS of the accuracies for four Compensation Module components and the Bistable Module, or 0.539%SPAN.

6.3.13 The maximum normal temperature extremes for the Auxiliary Building is listed as 60 to 105 'F (Ref. 6.6.2).

6.3.14 The radiation effect for the transmitters Is given in Reference 6.6.26 as +/-1 .0%URL for doses less than 1 MRadI hr and a TID less than 5 MRads. Reference 6.6.13 gives a dose of 2.1 MRads over a 3 year period for a Small Break LOCA. Although the dose given in Reference 6.6.13 may not bound all SBLOCA cases, it is assumed that doses will remain lower than 5MRads.

6.3.15 The MTE used to calibrate the EFIC Modules is much more accurate than one-half the accuracy of the devices being calibrated (Ref. 6.6.22 and 6.6.23). Therefore, in lieu of using RA/2 for the MTE accuracy (6.3.7), the actual accuracy of the MTE (+/-O.125%) will be used.

6.3.16 The vendor did not supply a temperature effect or power supply effect error specification for the EFIC modules. Based on the small deviations in both the Control Room temperature and the power supply voltage, and based on similar devices in the Control Room, It Is assumed that these deviations will have a negligible effect on the loop error.

ANO-1 Calculation No. DRN 05-3577 Pg. 51 of t3 Page 232 of 302 80-D-1083C-01, Rev. 7 6.3.17 The vendor for the EFIC system did not provide any drift data for the components.

Given the reference accuracy of the combination of the EFIC compensation module and bistable is 0.539 %span per 6.3.12 above, a drift allowance of approximately half of RA or 0.250 % is considered reasonable. This drift allowance will be increased to 0.258 % span by increasing it by a factor of 31130 to account for the former 30 day vs. 31 day test frequency M presently required by Technical Specifications.

z 6.3.18 The vendor specifies that the 625-ohm input resistor is a precision resistor (Ref. 6.6.10).

Per Reference 6.6.24, the resistor tolerance is +/-0.01%. The maximum errorwill result from maximum input, or 20 mADC and is determined as follows:

[625 + (.01%

  • 625)] * .02 A = 12.501 volts The maximum voltage (without error) would be 12.5 volts. Therefore, the error in percent span is (12.501-12.5)Ispan*100%= 0.0125 %Span. The error will be considered negligible per Assumption 6.3.6.

6.3.19 Per Reference 6.6.19, the Control Room temperature is 750 F with a temperature variance of +/-9 0F for the Abnormal and Accident Conditions.

16.3.20 The SG Low Level Initiate Bistable has a 9.900 second time delay (Ref. 6.6.39). The DRN 05-357 bistables are tested and assumed to be acceptable with a +/-0.5 second tolerance (Refs.

l 6.6.22 and 6.6.23). Therefore, the time response analysis will assume a 10.400 second delay.

second delay.

I6.3.21 The calibration procedures state that the Low SG Level Initiate Bistable is calibrated to 0.650%SPAN. This is slightly greater than the reference accuracy (RA) of 0.539% Span DRN listed in Section 6.4.4.2 and less than the former tolerance of 1.0% Span. Therefore, a 05-3577 setting tolerance (ST) will be added to the reference accuracy (RA) to obtain a device l tolerance (Dtol) of 0.650% SPAN.

I6.3.22 EFIC initiates on a low level of 11 inches above the lower tube sheet or 5 inches of calibrated span (3.3 % span, rounded), this is equivalent to an uncompensated voltage level of DRN approximately 2.833 volts or 2.84 volts (rounded). This trip is credited for a Loss of Feedwater 05-3577 (LOFW) event which does not assume a main steam or main feedwater line break. For LOFW the actual SG pressure would be expected to remain the same or increase above normal operating pressure at the time of trip intitiation. Table 6.4A.15 shows that for the range of bistable voltages from 2.5 to 6.0 vdc and for pressures equal to or greater than 900 psia the abnormal low level initiate bistable uncertainty (ABN SUlot) is bounded by

+2.02 -1.95 % Span.

ANO-1 Calculation No. DRN 05-3577 Pg 5 of 83 Page 236 of 302 80-D-1083C-01, Rev. 7 6.4.3.1 PROCESS MEASUREMENT ERROR (PME)

The process measurement error (PME) for this closed level loop is caused by density changes in the reference leg fluid due to ambient temperature variations. Since the loop is pressure compensated (Ref. 6.6.10), the density changes due to system pressure variations do not cause a process measurement error.

As the reference leg fluid temperature varies from the temperature assumed during calibration, the density of the reference leg fluid changes, causing the transmitter to sense a different differential pressure than expected, thus causing a bias process measurement error. The error will be positive when the reference leg temperature is greater than that assumed during calibration, and negative when the reference leg temperature is less than that assumed during calibration.

The assumed calibration conditions are given as follows: [At. 6-1]

Span = 143.99 "H2 0 (span of transmitter)

HR a 150 inches (height of reference leg)

Reference Leg Fluid:

TCAL = 120 0F (temperature assumed at calibration)

PCAL 61.7132 Ibm/ft3 (density assumed at calibration)

PCAL = 0.0357 Ibm/in3 (density assumed at calibration)

The error introduced by variations in the reference leg fluid density is calculated for the abnormal and accident conditions as follows:

Per Reference 6.6.10, the densities are stored in EPROM based on the ASME Steam Tables. Table 6.4.4.1 compares what the density is at the actual SG pressure with the density at the SG pressure with the uncertainty included.

This methodology conservatively assumes that no interpolation is performed.

Table 6.4.4.2 determines the minimum and maximum input voltages for the uncompensated level signal based upon the error associated with the level signal (Section 6.4.3).

Table 6.4.4.3 computes the expected output voltages without errors. The equation used for the expected output voltages (Section 6.2.0) is as follows:

vo= 1 + 2 3 .91*(APL-2.5) - 4.0*pst where vo is the output voltage fed to Pw - Pst the Bistables.

Tables 6.4.4.4, 6.4.4.5 and 6.4.4.6 compute the output error due to the error in the uncompensated level signal for the reference, abnormal and accident conditions, respectively.

The equation used is as follows:

VI o= 1 + 23.91*I(APL+/-LVLo)-2.5)] .4.0* Pst -v 0 Pw - Pst Table 6.4.4.7 computes the output error due to the error in the pressure signal for the reference, abnormal and accident conditions. This error is minimal compared to other errors in the loop. Therefore, for simplicity, only the accident error is considered for the pressure signal.

The equation used is as follows:

V2o = 1 + 23 .9 1*(APL-2 .5) - 4.0*p~t - vo with the densities based upon the pressuire PW - Pst signal with error PRSo Tables 6.4.4.8 and 6.4.4.9 compute the bias output error based upon the bias error in the uncompensated level signal for the abnormal and accident conditions, respectively.

The equation used is as follows:

Vob= I + 23.91*[(APL+/-LVLob)-2.5)] - 4.0*pst - v, Pw - POt

SETPOINT EVALUATION 71SG Low Level Initiate (SUI)

Credit is only taken for the initiation of EFW using this setpoint under the conditions of normal reactor building environment. Therefore, the uncertainties for the Abnormal Condition will be used in setpoint evaluation. Per Reference 6.6.40, the process limit for SG Low Level Initiate is 6 inches above the lower tubesheet (LTS) . Since this trip provides protection r-z for a decreasing level, the bistable positive abnormal error terms will be used.

The B&W calculation was originally prepared assuming an EFIC Low Level Initiate setpoint of DRN 8" above the lower tubesheet (LTS) and EFIC uncertainties of +3"/-5". The discussion 05- on the following page clarifies that the actual EFIC Low Level Initiate setpoint was 7.5" 3577 above the LTS and that the calculated EFIC uncertainties were +3.5/-5.5". The discussion further explains that the two assumptions (setpoint and uncertainty) counterbalance each other and that the calculated startup differential pressures should be applicable.

The B&W calculation assumes that the most likely SG pressure for spurious EFW DRN l actuation Is900 psia. Per Table 5.4.4.15 in Section 5.0, the calculated EFIC Low 05- l Level Initiate uncertainties are bounded by 2.50% or +/- 3.75 inches 3577 for a SG pressure of 900 psia.

The differences between the actual and assumed setpoints and between the actual DRN l (Table 5.4.4.1 5)and assumed uncertainties cause a minimal effect on the results of 05- the B&W calculation. Furthermore, the revised setpoint of 5.0 Inches (above the lower tap) 3577 gives additional margin. Therefore, the B&W calculation is considered applicable, and the possibility of spurious EFW actuation, during startup, Is minimal.
