BG&E Calculation CA07018, Revision I 1.0 PURPOSE The purpose of this calculation is to determine the total loop uncertainty of Main Feedwater pressure digital indications for the Caldon CheckPlus LEFM and Plant Computer.

Uncertainties are calculated for normal operating (non-harsh) conditions only.

2.0 COMPONENT LISTING This calculation applies to the following instruments:

Main Feedwater Pressure Transmitters 1-PT-1131A, B 1-PT-i 141A, B 2-PT-1131A, B 2-PT-I1141A, B I/E Converters II/E1C209A, B II/E1C209E, F 21/E2C209A, B 21/E2C209E, F A/D Converters 1M/P1C209A1, BI 1M/P1C209A2, B2 2M/P2C209A1, BI 2M/P2C209A2, B2 LEFM Electronic Unit ICPU 1 C209A 1, B I 1CPUIC209A2, B2 2CPU2C209AI, B11 2CPU2C209A2, B2 CCN-IC009002 Rev.

IA/D PrssureConverter Converter PC Transmitters Note: The loop configuration is determined from Reference 7.9 and Assumption 6.9.

4.0 METHOD OF ANALYSIS This calculation is performed in accordance with ES-028, Instrument Loop Uncertainty /

Setpoint Methodology. This calculation utilizes the Square Root Sum of the Squares (SRSS) methodology when all variables are random, independent and normally distributed. Bias uncertainties are combined algebraically with random uncertainties.

This calculation determines device uncertainties for the Main Feedwater pressure transmitters, I/E converters, and A/D converters and then combines these uncertainties to determine the total loop uncertainty for the digital indication of the LEFM. The error in this digital indication is the same as in the plant computer, since the signal is passed to the plant computer via a digital link.

TAG NUMBER: 1(2)-PT- 1131 A, B [7.2]

1(2)-PT-1141A, B MANUFACTURER: Rosemount [7.2]

MODEL NUMBER: 305 1CG5 [7.2]

SPAN: 0 to 1300 psig [7.2]

UPPER RANGE LIMIT 2000 psig [7.1]

(URL) 5.1.1 Per References 7.1, the Reference Accuracy for Range Code 5 transmitters with a turn down ratio (ratio of URL to Span) of less than 10:1 is +/- 0.065% Span. Per Reference 7.1, URL for these transmitters is 2000 psig. Per Reference 7.2, span for these transmitters is 1300 psig, yielding a turn down ratio of 1.54:1 (result of 2000 /1300). Therefore, the sensor Reference Accuracy (RAs) is given as:

RAs = +/- 0.065% Span 5.1.2 Per Reference 7.2, the setting tolerance for these sensors is +/- 0.25% Span.

Therefore, the Sensor Setting Tolerance (STs) is:

STs 0.250% Span 5.1.3 For conservatism, and to provide flexibility in the choice of test equipment, the Sensor Measurement and Test Equipment Effect (MTEs) is set equal to the sensor setting tolerance (STs). Therefore, MTEs + 0.250% Span CCN-IC009002 Rev. 1 Page 7 of 21.

BG&E Calculation CA07018, Revision 1 5.1.4 The Drift term (DRs) is given in Reference 7.1 as +/- 0.125% URL for 5 years with temperature variation limited to within +/- 50'F, and up to 1000 psi line pressure.

Reference 7.1 shows URL for range code 5 transmitters is 2000 psi. Per Reference 7.3, Turbine Building Maximum / Minimum design temperatures are 11 0°F / 60'F, respectively, ensuring that maximum temperature variation is bounded by +/-50'F. Line pressure effects are only applicable to differential pressure transmitters. Therefore, the Sensor Drift (DRs) is given as:

DRS 0.125%1X 2000psi X 100%Span X 50°F) %Span yl300psi 50* F)

DRs = +/- 0.192% Span 5.1.5 Per Reference 7.1, the Sensor Temperature Effect (TEs) is given as

+/- (0.0125% URL + 0.0625% Span) per 50'F for Range Code 5. Per Reference 7.1, URL for rarige code 5 transmitters is 2000 psi. Per Reference 7.3, Turbine Building Minimum / Maximum design temperatures are 60'F / I 10°F, respectively. Using Minimum / Maximum temperatures for calibration temperature and normal operating temperature ensures that maximum temperature variation (+/-50'F) is considered in determination of TES. Therefore, the Sensor Temperature Effect (TEs) is given as:

TEs +/- (0.0125%URL + 0.0625%Span) X 50'F 507F

[~0.0125% X 2000psi 50'F TEs= 12 0psi + 0.0625%Span X 50'F TEs = +/- 0.082% Span 5.1.6 Per Reference 7.1, Sensor Power Supply Effect (PSEs) is less than +/- 0.005% Span per volt variation. Reference 7.4 states that, for DC power supplies, considering a 5 volt variation in power supply voltage is conservative. Therefore PSEs is determined as follows:

PSEs = + 0.005%Span X 5voltsDC voltDC PSEs = +/- 0.025% Span Per Reference 7.4, uncertainties less than +/-0.050% are considered negligible.

Therefore, CCN-IC009002 Rev. I Page 8 of 21

BG&E Calculation CA07018, Revision 1 5.1.7 Per Reference 7.1, Sensor Vibration Effect (VEs) is negligible except at resonant frequencies. When at resonant frequencies, vibration effect is less than +/- 0.1% of URL per g when tested between 15 and 2000 Hz in any axis relative to pipe-mounted process conditions. Per Assumption 6.2, vibration is bounded by I g at the test conditions described. Per Reference 7.1, URL for range code 5 transmitters addressed in this calculation is 2000 psi. Reference 7.2 shows calibrated span for these transmitters is 1300 psig. Therefore VEs is determined as follows:

0.1% X 2000psi 1300psi VEs = +/- 0.154% Span 5.1.8 Per Reference 7.1, Sensor RFI Effects (RFIs) is +/- 0.1% Span from 20 to 1000 MHz and for field strength up to 30 V/m. Per Assumption 6.3, transmitters addressed in this calculation are not exposed to RFI conditions beyond the limits stated in the specification. Therefore:

RFIs = +/- 0.100% Span CCN-IC009002 Rev. I Page 9 of 21

BG&E Calculation CA07018, Revision 1 5.2 I/E CONVERTER CONSIDERATIONS (Subscript: pi)

TAG NUMBER: II/EIC209A, B, E, F 21/E2C209A, B, E, F MANUFACTURER: Analog Devices MODEL NUMBER: 5B32 SPAN: 4 to 20 mAdc [7.1]

PROCESS SPAN: (0 to 1300 psig) [7.2]

OUTPUT SPAN: 0-5 Vdc [7.6],

5.2.1 Per Reference 7.6, the initial accuracy at +25'C for the I/E Converters is +/- 0.05%

Span +/- 0.05% of Iz. The nonlinearity is defined as +/- 0.02% Span. The accuracy of the input resistance (20 Q) is shown to be +/- 0.1%. The accuracy of the input resistance is converted to percent of span at the highest input reading. This calculation conservatively computes Reference Accuracy, based on the combination of all these terms, via addition. The Converter 1 Reference Accuracy (RAp1) is computed as follows.

ACCRES= Accuracy of Input Resistance ACCRES = +/-0.1%x20 mAdc-4+/-Ad -+0.125% Span Iz = 4 mAdc 0.05% of 1z = 0.0005 x 4 mAdc x 100% Span -0.0125% Span

AINIT = Initial Accuracy AINIT = +/-0.05% Span +/- 0.05% of Iz (Conservatively Add)

AINIT = +/-0.05% Span + 0.0125% Span = +/-0.0625% Span RA 1 = +/-(0.0625 + 0.02 + 0.125)

RAp1 +/- 0.208% Span 5.2.2 Per Reference 7.4, the setting tolerance for these converters is set equal to the Reference Accuracy, since MCDS sheets do not yet exist. Therefore, the Converter 1 Setting Tolerance (STp1) is:

STpj = + 0.208% Span CCN-IC009002 Rev. 1 Page 10 of 21

BG&E Calculation CA07018, Revision I 5.2.3 For conservatism, and to provide flexibility in the choice of test equipment, the Sensor Measurement and Test Equipment Effect (MTEpi) is set equal to the Converter 1 Setting Tolerance (STpi). Therefore, MTEp1 + 0.208% Span 5.2.4 Per Assumption 6.6, Reference 7.6 does not provide a time-dependent drift specification for the I/E converter, and no historical data is available for analysis.

This device is a modern electronic module used for high accuracy situations; and drift should be near zero. Therefore, the drift term for these converters is conservatively set equal to the Reference Accuracy term. The Converter 1 Drift (DRp1 ) is defined:

DRp1 = +/- 0.208% Span 5.2.5 Per Reference 7.6, there are four (4) terms relating to temperature effect. This calculation conservatively computes temperature effect, based on the combination of all these terms, via addition. Note that the LEFM 1 + cabinets are air-conditioned and maintained within an approximate 10°F band, however, for conservatism, this calculation computes the I/E converter temperature effect, based on room temperatures without air conditioning. Per Reference 7.3, Turbine Building Minimum / Maximum design temperatures are 60'F / I 10°F, respectively. Using Minimum / Maximum temperatures for calibration temperature and normal operating temperature ensures that maximum temperature variation (+/-50'F) is considered in determination of TEpj. Therefore, the Converter I Temperature Effect (TEp1) is computed as follows:

Conservatively using the worst case voltage variation specified for the module of +5% (Assumption 6.7), the PSEp1 is determined as follows:

PSEp, = +/- 0.0002% Span Per Reference 7.4, uncertainties less than +/-0.050% Span are considered negligible. Therefore, PSEp1 = N/A 5.2.7 Per Reference 7.6, the Converter 1 RFI Effect (RFIpl) is defined by RFI Susceptibility, + 0.5% Span error @ 400 MHz, 5 Watts, at 3 feet. Per Assumption 6.8, the converters addressed in this calculation are not exposed to RFI conditions beyond the limits stated in the specification. Therefore:

RFIpi = +/- 0.500% Span CCN-IC009002 Rev. I Page 12 of 21

BG&E Calculation CA07018, Revision 1 5.3 A/D CONVERTER CONSIDERATIONS (Subscript: P2)

TAG NUMBER: 1M/P1C209A1, A2, B1, B2 2M/P2C209A1, A2, BI, B2 MANUFACTURER: Burr Brown MODEL NUMBER: ADS7825 SPAN: 0 to 5 Vdc [7.6]

PROCESS SPAN: (0 to 1300 psig) [7.2]

5.3.1 Reference 7.7 provides the uncertainty specifications for the Burr Brown A/D converters. However, Reference 7.8 is the accuracy analysis as provided by the vendor for these devices, when using an input span of 0 to 5 Vdc. The output of this analysis is the overall accuracy for the A/D converters. Per Reference 7.8, the overall uncertainty value is derived as +/- 17.5 mVdc. The Overall Accuracy of the A/D Converter (ACCp2) is computed as follows.

ACCP2 = +/-17.5 mVdc x 100%Span) ( lVdc (5 Vdc )1000 mVdc)

ACCP 2 = +/-0.350% Span In order to ensure that adequate temperature effects, etc., have been considered, an extra degree of conservatism is added, and +/-0.400% Span will be used for the Total Device Uncertainty of the A/D Converter (TDUp2). (Note that the LEFM "4+ cabinets are air-conditioned and maintained within an approximate 10°F band, so additional temperature effect uncertainties should not be present outside the uncertainty analysis of Reference 7.8.)

TDUp2 = + 0.400% Span CCN-IC009002 Rev. 1 Page 13 of 21

BG&E Calculation CA07018, Revision I 5.4 PROCESS MEASUREMENT EFFECT CONSIDERATIONS Not all of the transmitters addressed in this calculation are installed (as of Revision 1 issue), making precise determination of PMEb impossible at this time.

However, based on Assumption 6.1, an elevation difference of 30 feet can be used to quantify a bounding PMEb for use in this calculation. This process requires that transmitter calibration offsets be calculated and applied as stipulated on Reference 7.2. Per Assumption 6.4 this will be done prior to the initial calibration of each transmitter.

Reference 7.2 uses a conversion factor of 0.0361 psig / inH 20 to calculate offset.

Multiplying the conversion factor by (12 in) 3 / ft3 yields the actual calibration density, 62.3808 Ibm/ft3.

The following equation is used to calculate the PMEb due to sensing line density variations:

PMEb- h(pN-PC)N)( 100% Span [EQ-I]

144 1300ps- )

where, h = height of sensing line in feet (30 ft. per Assumption 6.1) 1300 psi = transmitter span PN = assumed sensing line fill fluid density during normal operation Pc = assumed sensing line fill fluid density to determine bounding calibration offset NOTE: The factor 144 is used to convert from lbf/ft2 to lbf/in 2 . At standard gravity, lbf may be replaced with Ibm.

Per Reference 7.3, the design minimum temperature is 60'F and the design maximum temperature is I 10°F in the area where the transmitters and sensing lines are located. To ensure the most conservative result, 60'F is considered calibration temperature and I 10'F is the maximum temperature during normal conditions. A conservative process pressure of 1000 psia is used for density determinations.

PN @ I 10°F / 1000 psia = 62.04833 Ibm/ft3 Reference 7.5 pc @ 607F / 1000 psia = 62.56809 Ibm/ft3 Reference 7.5 Note that the calibration density determined above (62.3808 lbm/ft3) is bounded by these conservative densities PN, and Pc.

BG&E Calculation CA07018, Revision I Substituting values in Eq. 1 yields:

Span PMEb = (30(62.04833-62.56809) (100%

144 ) 1300psi PMEb = -0.008% Span Per Reference 7.4, uncertainties less than +/-0.050% Span are considered negligible. Therefore:

BG&E Calculation CA07018, Revision 1 6.0 ASSUMPTIONS 6.1 UNVERIFIED ASSUMPTION - It is assumed that a Unit 1 LEFM plant modification will be implemented using the same converters, transmitters, transmitter calibrations, and configurations as presented in this calculation. In addition it is assumed that the vertical distance between transmitter centerline and process tap for the Unit 1 transmitters will not exceed 30 feet.

6.2 It is assumed that pipe mounted process vibrations for the transmitters addressed in this calculations are limited to 1 g between 15 and 2000 Hz in any axis.

6.3 It is assumed that transmitter RFI at the location of all transmitters addressed in this calculation is limited to 20 to 1000 MHz, and field strength of 30 V/m.

6.4 It is assumed that transmitter head correction (calibration values offset) is calculated and applied as part of the initial calibration of each transmitter addressed in this calculation, in accordance with the procedure stipulated in Reference 7.2.

6.5 Not used 6.6 Reference 7.6 does not provide a time-dependent drift specification for the I/E converter, and no historical data is available for analysis. This device is a modern electronic module used for high accuracy situations; and drift should be near zero.

Therefore, the drift term for these converters is conservatively set equal to the Reference Accuracy term.

6.7 It is assumed that the worst case power supply variation supplied to Converter 1 is

+/-5% of the supply voltage. This is considered conservjative, since this is the worst case power variation allowed by the device specifications.

6.8 It is assumed that Converter 1 RFI at the location of the Caldon hardware addressed in this calculation is limited to 400 MHz, 5 Watts, 3 feet from the K device.

6.9 The loop configuration is assumed to consist of the transmitter, I/E converter, and A/D converter, as presented in Section 3.0. This is based on the Unit 2 schematic drawings, Reference 7.9. It is assumed that this configuration will be as built for Units I and 2.

RE: Specification Clarification for 5832 Hi Kirk, You are correct about the Input Offset Spec. It should be 0.0025%, not 0.0025.

For the 5B32-01 module I get the following error terms vs. temperature

  • Input Offset 0.0025% of 4mA 4 0.luAIC or 0,00063%/'°C

" Output Offset 20uV/'C 4 0.064uAfC or 0,00040%/'C

Specification Clarification for 5632 Jim, Ijust called a moment ago and got your voice mail. Since I would like an email response anyway, I decided to write this up in an email.

I printed the 5232 specification from your website, and I marked it up to show where my question is. The specification in question is the Input Offset versus Temperature, which shows up in the table as 0.0025 of iz I degree C. The specifications above this are shown as percentages. I amwondering if this specification should say 0.0025% of lz /degree C.

4/13/2009 CCN-IC009002 Rev. I .Page 4 of 5

BG&E Calculation CA0701,8, Revision 1 Attachment 2 Page 2 of 2 We are working with a Caldon Ultrasonic flowmeter system, and we need tight accuracy. The room temperature could change as much as 50 degrees F in that room. We have a 4 to 20 mAdc signal coming in. If this specification is correct, I think Icompute an error just due to this effect as:

Input Offset due to Temp = (0.0025 x 4 mA) x (100% Span / 16 mAdc) x (1 degree C/1 degree F) x 50 degrees F = 1.74% Span.

This is a huge error for this module. If the specification actually should have a "%"listed, the error goes to around 0.0174% Span, which is much more reasonable in my opinion.

Anyway, if you get just a minute, I would really appreciate your looking at this specification and clarifying it for me. I am in a bit of a time crunch on this one, so your quick attention would be greatly appreciated.

Thanks for your time and consideration.

Transfer Functions Considering Only Offset Error and Full-Scale Error Using the values from the ADS7825 data sheet: Vos = +/-10 mV (+/-33LSBi where LSBi = 2 0*2A(-1 6 ))

and FSE = +/-10"0.25/100 = +/-25mV (+/-82LSBi). Note 4 states that the full-scale error includes the offset error which leads me to believe that the full-scale error with offset zeroed out is (82 - 33)*LSBi =

+/-49LSBi (since offset errors shift the ideal transfer function to the right or left). This means that there are two slopes for the worst case transfer functions which are slightly different from the slope of the ideal transfer function. This translates into slightly different values of LSB for the two cases: LSB1 for the slope corresponding to the -49 LSBI error; and, LSB2 for the slope corresponding to the +49 LSBi error given by:

4 LSBI. 10 - 49.LSBi LSBI = 0.30472 32768 LSBi = 0.30518 104 + 49.LSBi LSB237 LSB2 = 0.30563 32768 Then the offsets can be added in to give the worst case transfer functions where the offset and gain errors add together so as to make the total error the greatest. These two straight lines are the envelope of the bundle of all possible straight lines which meet the offset and FSE of the part.
