CALCULATION NO. RNP-IJJNST-1 128 PAGE NO. 7 REVISION 5 1.0 OBJECTIVE This calculation computes the loop uncertainties associated with the indication and trip functions provided by the Reactor Coolant System Flow instrumentation loops. The loops addressed in this calculation also provide input to the Emergency Response Facility Information System (ERFIS). Uncertainties at the input to ERFIS are calculated.
Uncertainties are calculated for normal and seismic conditions. This calculation develops the Reactor Protection System (RPS) setpoint associated with each instrument loop. This calculation also calculates the Allowable Value for the RPS setpoint addressed in this calculation.
The instrument loops containing the following components are addressed in this calculation:
FT-414 FT-415 FTI416 FQ-414 FQ-415 FQ-416 FC-414 FC-415 FC-416 FM-414 FM-415 FM-416 FI414 FI-415 FI416 FC-414/R FC-415/R FC416/R FM-414/R FM-415/R FM-416/R 1F-414 F-415 F-416 FT-424 FT425 FT-426 FQ-424 FQ-425 FQ-426 FC-424 FC-425 FC-426 FM-424 FM-425 FM-426 FI-424 F1425 F1426 FC-424/R FC-425/R FC-426/R FM-424/R FM-425/R FM-426/R F-424 F-425 F-426 FT-434 FT-435 FT-436 FQ-434 FQ-435 FQ-436 FC-434 FC-435 FC-436 FM-434 FM-435 FM-436 F1-434 FI-435 F1-436 FC-434/R FC-435/R FC-436/R FM-434/R FM-435/R FM-436/R F-434 F-435 F-436
CALCULATION NO. RNP-I!INST-1 128 PAGE NO. 8 REVISION 5 2.0 FUNCTIONAL DESCRIPTION The main components of the Reactor Coolant System are the Reactor, Steam Generators, the Pressurizer, and the reactor coolant pumps. The reactor coolant pumps provide forced cooling for the reactor during normal operation. The instrument loops addressed in this calculation serve to monitor reactor coolant flow in each loop and provide the following protective function:
- Low Flow Reactor Trip 2.1 NORMAL FUNCTION During normal operation, the instrument loops addressed in this calculation provide reactor coolant loop flow indication (FI-414, 415, 416, 424, 425, 426, 434, 435 and 436) and input to the Emergency Response Facility Information System (ERFIS).
2.2 ACCIDENT MITIGATING FUNCTION The instrument loops addressed in this calculation provide a Reactor Trip on Low reactor coolant flow in any loop. This trip serves to protect against DNB following a loss of forced reactor coolant flow. A Reactor Trip occurs when two out of three flow signals fall below the Low Flow setpoint. Per Reference 4.7.1,-this trip is credited in the Safety Analysis to :-;. -
protect against loss of forced coolant flow events.
2.3 POST ACCIDENT MONITORING FUNCTION Per Reference 4.6.2, these instrument loops are Regulatory Guide 1.97 D3 instruments, which are used as backup and diagnostic instrumentation.
2.4 POST SEISMIC FUNCTION These instruments are seismically qualified to ensure that safety / protection functions remain operable following a seismic event.

CALCULATION NO. RNP-IIJNST-1 128 PAGE NO. 14 REVISION 5 5.0 INPUTS AND ASSUMPTIONS 5.1 The accuracy of a typical test resistor is on the order of +/-0.01%. Therefore, the test resistors used during calibration are assumed to have a negligible impact on the overall uncertainty calculation.
5.2 Per Reference 4.7.6, the ambient temperature in the control room varies from 70'F to 770 F during operation. The calibration temperature for the indicator is assumed to be 60'F. Therefore, a change in temperature of 17'F (9.4 0 C) is used to compute the indicator temperature effect.
5.3 The Westinghouse 3110554-000 Computer Signal Conditioner is a high precision resistor. Based on the high accuracy of the resistor, the resistor has a negligible impact on the overall loop uncertainty computation.
5.4 Per Reference 4.7.6, the maximum temperature of the Hagan rack rooms is 820 F. Per Reference 4.6.1, the racks may experience an additional 10 0 F heat rise during operation.
The ambient temperature at the time of calibration is assumed to be 50'F. Therefore, a change in temperature of 420 F is used to compute the temperature effect associated with rack components.
820 F + 10 0 F - 50F = 420 F 5.5 Per Reference 4.6.1, reference accuracy typically includes the effects of linearity, hysteresis, and repeatability. The indicator reference accuracy given in Reference 4.4.2 is assumed to include the effects of linearity, hysteresis, and repeatability.
5.6 Per References 4.5.1 through 4.5.9, the I/V module is calibrated as part of a string. Per Reference 4.4.1, the I/V module is a resistor. Resistors typically experience negligible drift. Therefore, any resistor drift throughout the fuel cycle is negligible and is accounted for during the string calibration.
CALCULATION NO. RNP-I/INST-1 128 PAGE NO. 15 REVISION 5 5.7 Per Reference 4.1.4, the minimum operating temperature for Containment is 88 0 F. Per Reference 4.2.3, the maximum Containment temperature is 130T. The transmitters are not calibrated during normal plant operation. Therefore, the temperature at the time of calibration may be lower than 88 0 F. For conservatism, an assumed calibration temperature of 50'F is used to compute the transmitter temperature effect.
5.8 Per Reference 4.6.1, the normalized relationship between flow and differential pressure is given by the following equation:
FR=
The equation used to convert random uncertainties from % AP Span to % Flow Span is derived by taking the total derivative of the flow equation as follows:
=a A- _dp = dp aAP 2.%P d 2FR where, dFR = flow uncertainty (% Flow Span) dp = differential pressure uncertainty (% AP Span)
FR = actual flow rate (% Flow Span)
To obtain the equation used to convert random uncertainties from % Flow Span to %
AP Span, the equation given above is solved for "dp".
- dp = 2 (FRXdFR)
- - Multiply by a factor of 100 to obtain % AP Span 5.9 During normal operation, RCS flow remains constant at approximately 100% Flow which equates to 83.33% Flow Span (100% Flow Span = 120% Flow). Therefore, this calculation considers flow rates from 40 to 100% Flow Span.
CALCULATION NO. RNP-I/INST-1 128 PAGE NO. 16 REVISION 5 5.10 Per Reference 4.7.3, the analytical limit for the Low RCS Flow Reactor Trip setpoint is 87% of the Technical Specification minimum RCS flow requirement. These loops are scaled to provide an indication of 0 to 120% Flow. Per Reference 4.7.9, an analytical limit of 87% Flow Span is more conservative than 87% Flow. Therefore, the RCS Low Flow Reactor Trip setpoint is calculated based on an analytical limit of 87% Flow Span.
5.11 Per Reference 4.6.1, the normalized relationship between flow and differential pressure is given by the following equation:
FR = ,r--
The equation used to compute percent differential pressure span from a given percent flow span is obtained by solving the equation for AP. Therefore, AP=10%A Sak FR )2 AP' = 100%,P Span 100% Flow Span where, FR = Flow Rate 5.12 Per Reference 4.7.9, if all variables are treated as constants except density (p) and differential pressure (A0), the following equation is used to compute the theoretical flow through an elbow meter:
m = KIAp where, m = mass flow rate (Ibm / hr)
K = Flow Coefficient p = fluid density (Ibm / ft3 )
AP = differential pressure (inwc)
CALCULATION NO. RNP-IIINST-1 128 PAGE NO. 17 REVISION 5 For calibration conditions, the flow equation is as follows:
mc = Kid For operating conditions, the flow equation is as follows:
mN = K Assuming a constant mass flow rate for calibration and operating conditions, the following equation is written:
mN = mc Therefore, K/pN -Ap-N= KJpc AR Solving for APN yields the following equation:
(A AP c
CALCULATION NO. RNP-IAINST-1 128 PAGE NO. 18 REVISION 5 The process measurement effect, expressed in terms of % AP Span, due to changes in RCS fluid density from those assumed for calibration is obtained with the following equation:

N 100% AP Span AP Span p AP Span Therefore, PMEDENSnY (% AP Span) = P 100%APSpan AP Span 5.13 Per Reference 4.6.1, the normalized relationship between flow and differential pressure is given by the following equation:
FR = /i The equation used to convert bias uncertainties from % AP Span to % Flow Span is derived using perturbation methods. The flow equation with uncertainties in the differential pressure and flow terms is, FR+f= J /Vd where, FR = actual flow (% Flow Span) f = flow uncertainty (% Flow Span)
AP = differential pressure (% AP Span) dp = differential pressure uncertainty (% AP Span)
Taking the difference between the two equations given above yields the following, FR+f -FR = - =:> f =AP+dp-
CALCULATION NO. RNP-I/INST-1 128 PAGE NO. 19 REVISION 5 The equation given above is simplified by using the normalized relationship between flow and differential pressure as follows,
- f =FR 2 +dp-FR
- - Multiply by a factor of 100 to obtain % Flow Span To obtain the equation used to convert from % Flow Span to % AP Span, the equation given above is solved for "dp". Therefore, the equation used to convert from % Flow Span to % AP Span is as follows,
- dp= (FR +f) 2 _FR2
- - Multiply by a factor of 100 to obtain % AP Span 5.14 Per Reference 4.2.4 and Design Input 5.16, RCS cold leg temperature during normal operation is approximately 547.6 0 F at 2250 psia, which is in agreement with Robinson Dynamic Plant Data PLT View. Per Reference 4.7.10, the uncertainty associated with the RCS average temperature is +/-40 F. For conservatism, RCS cold leg temperature is assumed to vary between 537.6 0 F and 557.60 F during normal operation. Therefore, per Reference 4.7.5, the following densities are used to compute the process measurement effect associated with density variations of the RCS cold leg fluid:
Pc = 47.01789 Ibm / ft3 (calibration, 547.60 F)
PMAX= 47.64037 Ibm / ft3 (maximum, 537.60 F)
PMIN = 46.36606 Ibm I ft3 (minimum, 557.6 0 F)
CALCULATION NO. RNP-IIINST-1 128 PAGE NO. 20 REVISION 5 5.15 HBR2 replaced all RCS Flow Transmitters with Rosemount transmitters. After the new transmitters were installed, the differential pressure (AP) required to indicate 100% RCS Flow was determined for each of the 9 RCS Flow Transmitters. Based on discussions with station personnel and a review of Reference 4.7.7, the RCS Flow Transmitter 100% AP values were scaled to the process range of 0 to 120% RCS Flow, yielding AP values for 120% RCS Flow. These values were then documented in the scaling documents for their respective transmitters. Since the RCS flow transmitters have not been normalized to 100% flow since the initial scaling, it is assumed that the existing scaling documents (Reference 4.6.4) contain the correct span values for each of the 9 RCS Flow Transmitters. [Note that the calibration values in 4.6.4 have been rounded to the nearest inwc, so the actual transmitter 100%
range value must be calculated using the input / output recorded in Reference 4.6.4.]
5.16 The RCS cold leg temperature is based on 0% tube plugging in the Steam Generators, which is the most conservative value.
5.17 The computations performed in this calculation are carried to several significant digits, but are presented rounded to two decimal places. Hand verification using the rounded values may result in slightly different results due to round off error.

Per Reference 4.6.2, the indication functions are required to provide backup indication following an accident. However, Category 3 loops are not required to be qualified for harsh environmental conditions. Therefore, accident effects are not computed for the indication functions.
Per Reference 4.7. 1, the Low Flow Reactor Trip is credited in the safety analysis for terminating loss of forced coolant flow events. Per Reference 4.7.2, this trip serves to prevent violating the DNBR limit due to low flow in one or more loops. This trip is not credited to terminate any event which results in a harsh Containment environment. Therefore, accident effects are not included in the total loop uncertainties for this trip function.
However, this function must be available following a seismic event. Therefore, seismic uncertainties are included in the total loop uncertainties for this function.

A precision flow calorimetric is performed after each refueling outage to verify that RCS flow remains above the minimum Technical Specification flow (Reference 4.6.5). Therefore, the only process measurement effects which need to be considered are normal RCS density variations during operation and the uncertainties associated with the precision flow calorimetric. Thermal Expansion Effects and Installation Effects are calibrated out as a result of the normalization process.
6.4.2 Flow Calorimetric Uncertainties NOTE The 2.6% RCS Flow value in the following paragraph was determined prior to the implementation of the ultrasonic feedwater flow monitoring instrumentation system. This system provides indications of feedwater flow that are much more accurate than previously available. As a result, the uncertainty of Secondary Heat Balances has been significantly reduced. Since the uncertainty of the Secondary Heat Balance is used in the determination of the +/- 2.6% Flow value used below, the value should remain bounding and contain some margin that could be captured in the future if desired.
Per Reference 4.7.7, the uncertainties associated with the precision flow calorimetric are
+/-2.6% Flow which equates to +/-2.17% Flow Span (2.6% Flow / 120% Flow

Per Reference 4.4.3, the static pressure span effect correction uncertainty is +/-0.50% Reading per 1000 psia. Per Reference 4.2.4, the nominal operating pressure of the RCS is 2250 psia.
