Weinberg from Dr. D. Halmi, Senior Principal Engineer, Flow Metering and Calcs, BIF Industries, dated 3/23/77. 50.59 Applicability Review 50.59 Pre-Screening RECORD OF REVISION Rev. 0 Original Issue. This calculation replaces Calculations C10854-2 Rev.2, C10854-3 Rev.1, and C10854-5 Rev.0. This calculation is written as a Channel Statistical Allowance (CSA) Calculation versus a Setpoint Calculation.

1.0 PURPOSE The purpose of this calculation is to determine the Channel Statistical Allowance (CSA) values for the Steam Flow and Steam Line Pressure inputs into the Engineered Safety Features (ESF) logic channels. The applicable Steam Flow channels F-464, F-465, F-474, and F-475 provide input into the Steam Line Isolation function. The applicable Steam Line Pressure channels P-468, P-469, P-478, P-479, P-482, and P-483 provide input into the Safety Injection function.

Because of the difference in parameters measured, separate CSA's will be determined for the Steam Line Isolation and Safety Injection functions.

Engineering Work Sheet Calculation Number: Revision: Addendum: Page 4 of 23 C10854 0 N/A 2.0 METHOD OF ANALYSIS This calculation uses the methodology presented in STD-EEN-0304, Revision 6, Calculating Instrumentation Uncertainties by the Square Root of the Sum of the Squares Method (Reference 5.1). The CSA determined in this calculation is a derivation of the following generic equation presented in STD-EEN-0304, Revision 6, Section 6.1:

CSA = SE +/- [EA² + PMA² + PEA² + (SCA + SMTE)² + SD² + SPE² + STE² + SPSE2 +

(M1 + M1MTE)² + (M2 + M2MTE)² + ...+ (Mn + MnMTE)² + RD² + RTE² + RRA²]

(Equation 1)

The error terms in Equation 1 are consistent with standard industry definitions and are described in Section 8.0 and in detail in Reference 5.1.

The CSA calculations are based on static conditions. Tolerances associated with the time constants for any dynamic modules are not taken into account in the development of the CSA.

The error terms for the Steam Flow channels will be calculated using units in % P Span. The resulting CSAs will be converted to process units (lbm/hr).

The conversion from % P Span to % of Flow Span is found in Reference 5.24 and is given as:

% Flow Span = % P Span

• 0.5 * (Flow Max / Flow X) (Equation 2)

(where X is the flow rate of interest)

Transposing Equation 2 yields the following:

% P Span = % Flow Span / 0.5 * (Flow Max / Flow X) (Equation 3) 3.0 DESIGN INPUTS The design inputs are manufacturer's published data sheets, active (current) calculations, station controlled drawings and other controlled documents as listed in Section 5.0, References.

4.0 ASSUMPTIONS 4.1 Based on Reference 5.12, all test data is referenced to the rack 10 Test Point Resistor (TPR), therefore the errors associated with the installed DB Box resistors used to convert the loop current to an applied input voltage to the Foxboro or NUS module under test is included in the overall error of the Foxboro or NUS module as referenced to the rack TPR.

4.2 According to References 5.10, 5.11, and 5.12, a Fluke 45 Digital Multimeter (DMM) is used to perform the transmitter and rack module calibration. According to Reference 5.13, the DC Voltage accuracies for the ranges of interest are as follows:

Engineering Work Sheet Calculation Number: Revision: Addendum: Page 5 of 23 C10854 0 N/A Range Desired Acceptance Range 300 mV 300 mV 299.92 to 300.08 mV 3V 3V 2.9992 to 3.0008 V 30 V 30 V 29.992 to 30.008 V Range Desired Acceptance Range 1000 mV 900 mV 899.76 to 900.24 10 V 9V 8.9976 to 9.0024 At Kewaunee, there are six possible voltage spans that could be present in the Reactor Protection System; i.e., 40 to 200 mVDC, 100 to 500 mVDC, 1 to 5 VDC, 0.4 to 12.4 VDC, 2 to 10 VDC, and 0 to 10 VDC. The DC voltage accuracies converted to % of span are given below.

100 to 500 mVDC (1000 mV range) accuracy = (0.24 mVDC / 400 mVDC)

• 100% = 0.06% of span 0.4 to 12.4 VDC (30 V range) accuracy = (0.008 VDC / 12 VDC)

• 100% = 0.07% of span 2 to 10 VDC (30 V range) accuracy = (0.008 VDC / 8 VDC)

• 100% = 0.10% of span 0 to 10 VDC (30 V range) accuracy = (0.008 VDC / 10 VDC)

• 100% = 0.08% of span 40 to 200 mVDC (300 mVDC range) accuracy = (0.08 mVDC / 160 mVDC)

• 100% = 0.05% of span 1 to 5 VDC (10 V range) accuracy = (0.0024 VDC / 4 VDC)

• 100% = 0.06% of span This calculation will be bounded using an accuracy of +/- 0.1% of span for the Fluke 45 DMM for all possible conditions for ranges 30 VDC or less. It is acceptable for the calibration procedures to use a DMM with accuracy specifications equal to or better than the Fluke 45 DMM.

4.3 Reference 5.11 specifies that a deadweight tester is used in the calibration of the Steam Pressure transmitters. Reference 5.10 specifies a pressure measuring device with an accuracy of 2.172 H2O is used in the calibration of the Steam Flow transmitters. A pressure measuring device with equivalent or better accuracy may be substituted.

Engineering Work Sheet Calculation Number: Revision: Addendum: Page 6 of 23 C10854 0 N/A 4.4 This calculation is applicable for normal (non-harsh) conditions only. Therefore, the Environmental Allowance (EA) term is assumed to be zero. This term includes the effects due to degradation of cable insulation (IR) and the effects of high steam pressures and temperatures (SPTE) and radiation (RE) during an accident .

8.1.1 SE = Systematic Error No Systematic Error has been identified for these loops.

SE = 0.000% P Span 8.1.2 EA = Environmental Allowance No Environmental Allowance will be used in this calculation. (Assumption 4.4)

EA = 0.000% P Span

Engineering Work Sheet Calculation Number: Revision: Addendum: Page 10 of 23 C10854 0 N/A 8.1.3 PMA = Process Measurement Accuracy At lower flow rates Steam Enthalpy due to pressure and moisture changes will impact the accuracy of the process measurement. Because of this a PMA term of +/- 0.3% of flow span will be applied to the High (but not the High-High) Steam Flow bistables. (Reference 5.23)

The PMA value given in terms of flow is converted to % P span as follows:

% P Span = PMA (% Flow) / 0.5 * (Flow Max / Flow X) (Equation 3)

PMA = +/- 0.3% flow span Flow Max = 4.47 x 106 lbm/hr (Reference 5.12)

FlowHi Steam = 0.494 x 106 lbm/hr (Reference 5.12)

PMA in % P Span = 0.3% / 0.5 * (4.47 x 106 lbm/hr / 0.494 x 106 lbm/hr) = 0.066% P Span PMAHi Steam = +/- 0.300% Flow Span = 0.066% P Span 8.1.4 PEA = Primary Element Accuracy Three tolerances for the BIF Steam Tubes were identified in Section 3.3.4 of Attachment 1:

1) The Condition of Tube was given a tolerance of 0.2%. For conservatism that tolerance will be increased to 0.5%.

2) The Basic Tolerance is given as 0.75%.

3) The Installation Effect is given as 0.7%.

For conservatism, these tolerances will be added numerically resulting in a tolerance of 1.95%.

The PEA value given in terms of flow is converted to % P span with respect to Flow Nom as follows:

% P Span = PEA (% Flow) / 0.5 * (Flow Max / Flow X) (Equation 3)

PEA = +/- 1.95% of flow span Flow Max = 4.47 x 106 lbm/hr (Reference 5.12)

Flow Nom = 3.82 x 106 lbm/hr (Reference 5.23)

PEA in % P Span = 1.95% / 0.5 * (4.47 x 106 lbm/hr / 3.82 x 106 lbm/hr) = 3.333% P Span PEA = +/- 1.950% Flow Span = 3.333% P Span

Engineering Work Sheet Calculation Number: Revision: Addendum: Page 11 of 23 C10854 0 N/A 8.1.5 SCA = Sensor Calibration Accuracy Reference 5.10 provides a transmitter calibration accuracy of +/- 0.25% P span.

SCA = +/- 0.250% P Span (Reference 5.10) 8.1.6 SMTE = Sensor Measuring and Test Equipment The following Measuring and Test Equipment or its equivalent is used for calibration of the transmitters:

1) SMTE1 = DMM, Fluke Model 45 or equivalent with an accuracy of +/- 0.1% of P span SMTE1 = +/- 0.100% of P span (Assumption 4.2)

2) SMTE2 = 10 Test Point Resistor (TPR) with an accuracy of +/- 0.01% P span SMTE2 = +/- 0.010% P span (Reference 5.16)

3) Reference 5.10 states that a pressure measuring device with an accuracy of 2.172 H2O or better is used for the calibration of the Steam Flow transmitters.

SMTE3 = (2.172 H2O / 1438.3 H2O)

• 100% = +/- 0.151% P span (Reference 5.10)

Therefore the Sensor Measuring and Test Equipment (SMTE) accuracy is equal to:

SMTE = [ (SMTE1 + SMTE2)2 + SMTE32 ] 1/2 SMTE = [ (0.100 + 0.010)2 + (0.151)2 ] 1/2 SMTE = +/- 0.187% P Span 8.1.7 SD = Sensor Drift According to References 5.8 and 5.25 the sensors are Rosemount 1153DD6 transmitters.

Based on Reference 5.8, the Rosemount Model 1153DD6 transmitter has a drift value of +/- 0.2%

of upper range limit (URL) for 30 months. The calibrated span of the instrument per Reference 5.10 is 1438.3 H2O. The upper range limit of the transmitter is 100 psi (2773.0 H2O) per Reference 5.8. Therefore the Sensor Drift allowance for a period of up to 30 months is:

SD = (+/- 0.002

• 2773 H2O / 1438.3 H2O)

• 100%

SD = +/- 0.386% P span (References 5.8, 5.10 and 5.25)

Engineering Work Sheet Calculation Number: Revision: Addendum: Page 12 of 23 C10854 0 N/A 8.1.8 SPE = Sensor Pressure Effect Reference 5.8 specifies a Static Pressure Zero Effect and a Static Pressure Span Effect.

The Static Pressure Zero Effect is adjusted out by calibration procedures. (Reference 5.10)

The Static Pressure Span Effect equals +/- 0.5% of input reading per 1000 PSIG. (Reference 5.8)

For conservatism, this calculation will assume the maximum pressure of 1005 PSIG from Reference 5.2 when determining the Static Pressure Span Effect.

Therefore, the Static Pressure Span Effect = 100% * (1005 PSIG

• 0.005) / 1000 PSI SPE = +/- 0.503% P Span 8.1.9 STE = Sensor Temperature Effect The Rosemount Instruction Manual states the temperature effect for Range Code 6 is:

+/- (0.75% of URL + 0.5% span) per 100°F (Reference 5.8)

Upper Range Limit = 2773 H2O (100 PSI) (Reference 5.8)

Transmitter Span = 1438.3 H2O (Reference 5.10)

Temperature Span = 80°F (References 5.3 & 5.20)

Engineering Work Sheet Calculation Number: Revision: Addendum: Page 18 of 23 C10854 0 N/A 8.2.6 SMTE = Sensor Measuring and Test Equipment The following Measuring and Test Equipment or its equivalent is used for calibration of the transmitters:

1) SMTE1 = DMM, Fluke Model 45 or equivalent with an accuracy of +/- 0.1% of P span SMTE1 = +/- 0.100% of span (Assumption 4.2)

2) SMTE2 = 10 Test Point Resistor (TPR) with an accuracy of +/- 0.01% P span SMTE2 = +/- 0.010% of span (Reference 5.11)

The surveillance procedures for the calibration of the Steam Generator Steam Pressure transmitters (Reference 5.11) specify the use of a Deadweight Tester for the measurement of the pressure input during calibration. To allow for future changes in the calibration methods, this calculation will assume that a pressure gauge (temperature compensated) with an accuracy of +/- 2.0 psig or better is used in the calibration of the transmitter. This accuracy will bound that of the Deadweight Tester and also a Heise Handheld with Pressure Module.

Upper Range Limit = 3000 psi (Reference 5.8)

Transmitter Span = 1400 psi (Reference 5.11)

Temperature Span = 70°F (Reference 5.20)

Note: The Environmental Qualification Plan specifies a Design Input Temperature of 120°F. It also states that the Average Temperature found at Thermocouple L1 in the Shield Building/Annulus is 78.3°F. For conservatism, this calculation will assume a minimum temperature of 50°F to account for a transmitter calibration performed when the building is at its coolest. This results in a Temperature Span of 70°F.
