1.0 PURPOSE
The purpose of this calculation is to determine the Channel Statistical Allowance (CSA) values associated with the Reactor Protection and Safety Injection Functions of the Pressurizer Pressure Protection Loops. The Pressurizer Pressure Head correction is also included for reference purposes only. The applicable instrumentation loops are P-429, P-430, P-431, and P-449. The loops are similar; therefore the CSA values presented in this calculation will be applicable for all of the loops.
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 + SPSE 2 + (M1 + M1MTE)² + (M2 + M2MTE)² + ...+ (Mn + MnMTE)² + RD² + RTE² + RRA²] (Equation 1)
The terms M1 through Mn refer to individual rack modules within the Pressurizer Pressure Protection Loops. The term MnMTE refers to the Module Measuring and Test Equipment where n is the module number as shown on the Functional Block Diagram in Section 7.0. Finally, the EA term will be removed from the equation for normal conditions since there is no environmental allowance for non-harsh conditions. These changes result in the following equation.
For normal conditions:
CSA = SE +/- [PMA² + PEA² + (SCA + SMTE)² + SD² + SPE² + STE² + SPSE 2 + (M1 + M1MTE)² + (M2 + M2MTE)² + ...+ (Mn + MnMTE)² + RD² + RTE² + RRA²] (Equation 2)
For harsh (DBE) conditions:
CSA = SE +/- [EA 2 + PMA² + PEA² + (SCA + SMTE)² + SD² + SPE² + STE² + SPSE 2 + (M1 + M1MTE)² + (M2 + M2MTE)² + ...+ (Mn + MnMTE)² + RD² + RTE² + RRA²] (Equation 3)
The error terms in the equations above are consistent with standard industry definitions and are described in Section 8.0 and in detail in Reference 5.1.

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 The Environmental Allowance (EA) term is assumed to be zero for normal (non-accident) conditions. For abnormal operating conditions the EA term includes the effects on the field cables due to degradation of cable insulation (IR), the effects on the transmitter due to increased radiation (RE), and the effects on the transmitter due to elevated steam pressure and temperature (SPTE). 4.2 Based on Reference 5.16, 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. 4.3 According to References 5.15 and 5.16, a Fluke 45 Digital Multimeter (DMM) is used to perform the transmitter and rack module calibration. According to Reference 5.14, the DC Voltage accuracies for the ranges of interest are as follows:
Range Desired Acceptance Range 300 mV 300 mV 299.92 to 300.08 mV 3 V 3 V 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 9 V 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 Engineering Work Sheet Calculation Number:

N/A Page 6 of 23 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.
4.4 The loops will be calibrated with a 0-3000 psig Heise Pressure Module or equivalent with an accuracy of + 0.05% of span or better.

SPSE = Sensor Power Supply Effect According to Reference 5.21, Rosemount Model 1154SH9 differential pressure transmitters are used for the Pressurizer Pressure Channels. According to Reference 5.8, the Sensor Power Supply Effect for this model is less than 0.005% of output span per volt. The nominal load resistance for the Pressurizer Pressure Channels is approximately 1500 (Reference 5.16). Based on Figure 6-2 in Reference 5.8, the nominal power supply voltage at 1575 at 20 mA is 45 VDC. From Figure 6-2, the high end qualified power supply voltage is 45 VDC and the low
end voltage is 13.5 VDC.
Based on References 5.15 and 5.16, the power supply output voltage is not checked during the performance of the Channel Calibration Procedure or the Pressurizer Pressure Transmitter Calibration Procedure, therefore to bound all possible conditions, a power supply output tolerance of + 31.5 VDC (i.e. 45 VDC - 13.5 VDC) will be used to determine the Sensor Power Supply Effect.

RD = Rack Drift The superseded calculations specified a drift value derived from previous testing. However, that data is not current and Kewaunee is replacing Foxboro rack modules with NUS Instruments equivalents where sufficient drift trends have not been established. Therefore, the standard and conservative value of + 1.0% of span as referenced in STD-EEN-0304, Revision 6 will be used in this calculation.

N/A Page 16 of 23 RTE = Rack Temperature Effect For Kewaunee calculations the Rack Temperature Effect term was either assumed to be embedded in the Rack Drift term or set to zero percent of span. However, the effects of rack temperature changes have not been monitored or documented. Therefore, the standard and conservative value of + 0.5% of span as referenced in STD-EEN-0304, Revision 6 will be used for this calculation.
RTE = + 0.500% of span (Reference 5.1)
RRA = Rack Readability Allowance Rack Readability Allowance (RRA) is applicable for the indication portion of the loops. This calculation is determining the CSA value associated with the applicable trips and not the indication. Thus, RRA = + 0.000% of span (Reference 5.1)

N/A Page 20 of 23 CSA CALCULATION FOR ABNORMAL OPERATING CONDITIONS
Abnormal operating conditions have been divided into two categories. The first category considers the environment under which the loop would function during a Design Basis Event (DBE). The second category considers the environment under which the loop would function following this DBE and continuing for 120 days (POST-DBE).
CSA Calculation for DBE Environment During a DBE, elevated temperatures and pressures as well as higher radiation dose rates will exist in the containment. DBE conditions will affect the function of both the loop sensor and its associated cabling. The DBE effects are designated as the Environmental Allowance (EA) term in Equation 3. They will be accounted for in the following error components:
- 1. Insulation Resistance Effects (IR) - systematic errors caused by the effects of leakage currents as a function of insulation resistance.
- 2. Steam Pressure / Temperature Effects (SPTE) - environmental allowance caused by elevated temperatures and pressures.
- 3. Radiation Effects (REdbe) - bias error caused by the effects of increased radiation dose rate.
Per Reference 5.1, the EA terms that are random errors as stated by the manufacturer will be placed under the radical. Any EA term that is systematic or a bias error will be placed outside of the radical and summed with the SE term(s), if applicable. According to Reference 5.8, the SPTE and RE dbe terms are random errors. Based on Reference 5.1, the IR term is systematic and will be treated as a bias error outside of the radical.
IR = Insulation Resistance Effects
The equation used to calculate IR is taken from Reference 5.1 and is given below:
IR = [(V s - R e
- I t) / I t (R c + R e)]
- 100%
The equation above calculates the error in percent of reading. The equation must be modified to calculate the IR error in percent of span, where I t in the denominator will become I t'. I t' will be equal to the instrument span in mADC (i.e., 16 mADC). The revised equation used to calculate
the IR error is:
IR = [(V s - R e
- I t) / I t' (R c + R e)]
- 100%
Where:
IR = percentage of systematic error
V s = Loop Power Supply Voltage (i.e., 43 VDC for Foxboro/NUS power supplies. Ref. 5.20)
R e = Input Load Impedance (10 TPR)
I t = Device Output Current [(1830 psig (1) - 1700psig)/800 psig]
- 16 mADC = 2.6 mADC I t' = Output Current Span (16 mADC)
