LE-0113 Ow Reactor Core Thermal Power Uncertainty Revision 1 meI____ n. Calculation Unit 1 1.0 PURPOSE The purpose of this calculation is to determine the uncertainty in the reactor core thermal power (heat balance) calculation performed by the Plant Process Computer (PPC). This calculation will evaluate the contribution of the different instrument channel loop uncertainties to the uncertainty of the Core Thermal Power (CTP) value using the reactor heat balance relationship when the plant is operating at 100% rated power under steady state conditions.

This calculation is being performed in support of the licensing amendment for Measurement Uncertainty Recapture (MUR) power uprate. The calculation provides the uncertainty in the value of CTP calculated by the Plant Process Computer at MUR rated conditions for use in requesting an increase in the CTP licensing limit for Limerick Generating Station Unit 1. Therefore, there are no acceptance criteria. The number is simply stated for use in preparation of the License Amendment Request.

1.1 FUNCTIONAL DESCRIPTION AND CONFIGURATION Limerick Generation Station (LGS) Unit I will be installing highly accurate ultrasonic feedwater flow meters per Engineering Change Request (ECR) LG 09-00096. This calculation will determine the uncertainty in Core Thermal Power calculation when the reactor heat balance is performed using the process computer with the feedwater flow and temperature measurement input supplied by the Caldon Leading Edge Flow Meters Check Plus (LEFMv$+) System Ultrasonic Flow Meters (UFM).

2.0 DESIGN BASIS Various plant parameters are monitored by the NSSS computer to develop the reactor core thermal power calculation. On June 1, 2000 Appendix K to Part 50 of Title 10 of the Code of Federal Regulations was changed to allow licensees to use a power uncertainty of less than 2 % in their LOCA analysis. The change allowed licenses to recapture power by using state-of-art devices to more precisely measure feedwater flow. Feedwater flow inaccuracy is a large contributor in the uncertainty determination of reactor power. This calculation is being performed in the support of a License Amendment Request (LAR) for a MUR power uprate.

2.1 INPUTS Table 2-1 lists the parameters which specify input to the core thermal power calculation, their uncertainty values, and the source of these values.

The values for Feedwater Flow, Feedwater Temperature, and Reactor Narrow Range Dome Pressure are specified by separate calculations as follows (Ref. 4.8.6 thru 4.8.8):

• LEAE-MUR-0001, Bounding Uncertainty Analysis for Thermal Power determination

" LE-01 16, Reactor Dome Narrow Range Pressure Measurement Uncertainty The uncertainties for Reactor Water Clean-up (RWCU) Flow Rate, RWCU Inlet Temperature Thermocouple, Control Rod Drive (CRD) Flow Rate, and Recirculation Pump Power are calculated in individual sections of this calculation. Recirculation Pump Efficiency is given in calculation LM-0552 (Ref. 4.8.2). The thermal loss due to radiated heat loss to the drywell is specified by separate calculation LM-553 (Ref. 4.8.3) for calculating the reactor heat balance by hand.

Other inputs and the related source references are listed in the Table 2-1.

LE-0113 WP Reactor Core Thermal Power Uncertainty Revision I

______________ Calculation Unit 1 3.0 ASSUMPTIONS AND LIMITATIONS 3.1 Standard practice is to specify calibration uncertainty in calculations equal to the uncertainty associated with the instruments under test (Ref. 4.1.1).

3.2 Instrumentation uncertainty caused by the operating environment's temperature, humidity, and pressure variations are evaluated when these error sources are specified by the instrument's vendor.

If the instrument's operating environment specifications bound the in-service environmental conditions where the equipment is located and separate temperature, humidity, and pressure uncertainty terms are not specified for the instrument, then these uncertainties are assumed to be included in the manufacturer's reference accuracy specification.

3.4 Published instrument vendor specifications are considered to be based on sufficiently large samples so that the probability and confidence level meets the 2cr criteria, unless stated otherwise by the vendor.

3.5 Seismic effects are considered negligible or capable of being calibrated out unless the instrumentation is required to operate during and following a seismic event.

3.6 The insulation resistance error is considered negligible unless the instrumentation is required to operate in an abnormal or harsh environment.

3.7 Regulated instrument power supplies are assumed to function within specified voltage limits; therefore, power supply error is considered negligible with respect to other error terms unless the vendor specifically specifies a power supply effect.

3.8 Measurement of CRD hydraulic system purge water temperature is found to be accurate within t 0.7 'F per Attachment 1. The enthalpy of water at the CRD normal operating pressure of 1448 psig as listed in P-300 (reference 4.4.1) and normal operating temperature of 97.2 *F (Table 2-1) are used to determine uncertainty of the CRD hydraulic system enthalpy because this is more conservative than using the higher temperatures normally found during operation.

3.9 The CRD system uses a Rosemount 1151 differential pressure transmitter (Section 2.4.3), which is mounted in a radiation exposure area. A radiation exposure effect is not specified for the Model 1151 transmitter; therefore the radiation effect applicable to this transmitter is assumed to be 10 % of span.

This assumption is considered conservative based on three factors: (1) periodic surveillance is performed on this transmitter and it is required to operate within 0.5 % of span or maintenance activities must be performed. Existing calibration records did not indicate anything unusual occurring with the calibration of these transmitters in this service. (2) A Rosemount Model 1153 series B transmitter is rated for radiation exposure and may be expected to have a radiation effect of +/- 4 % of upper range limit (URL) during and after exposure to 2.2 x 107 rad (Section 7.3.1.16). However, this exposure is over a 1000 times the expected exposure for the CRD system flow transmitter s during normal service. The estimated TID during normal service for the CRD flow transmitter is 3.51 x 104 rad (Section 4.4.2). The 10 % span estimated effect is more than an order of magnitude greater than the threshold for maintenance activity and of the same order of magnitude of the effect on a similar transmitter with 1000 times the exposure.

3.10 Interim results are rounded to the level of significance of the input data to avoid implying that a higher level of precision exists in the calculated values. For example, uncertainty may be specified by a supplier to one significant figure (e.g., 0.5 %). This value says that the level of significance associated with this uncertainty is one part in two hundred. The results are rounded when the numeric value of a result implies a higher level of significance than what the input data suggests.

LE-01 13 Reactor Core Thermal Power Uncertainty Revision I

_ __ __ _ _ Calculation Unit 1 3.11 An uncertainty of +/- 10 psig is assumed for the feedwater pressure and the CRD outlet pressure to conservatively cover the variations in the actual steam dome or reactor vessel pressure. The variation in pressure has a negligible effect on the enthalpy of the feedwater.

3.12 An uncertainty of 10 % is assumed for the RPV thermal radiation heat loss term, QRAD, based on a review of calculation LM-0553 (Reference 4.8.3). LM-0553 determined the RPV heat loss by calculating the actual heat load in the drywell, subtracting the heat load attributed to any operating equipment in the drywell, and proportioning the heat load based on the shared chilled water system design flows assigned to Unit 1 drywell and Unit 2 drywell on a percentage basis. LM-0553 assumes Unit 1 and Unit 2 are operating at 100 percent power and the drywell air cooling fans are aligned as designed.

3.13 Steam table excerpts have been provided for convenience as Attachment 6, National Institute for Standards and Technology (NIST) Thermophysical Properties of Water, as extracted from the NIST fluid properties WebBook (Reference 4.9.3). For conservatism, factors of one-half the least significant figure in the tables are used for the interpolation error. The factors are 0.05 Btu/ibm for vapor and 0.005 Btu/Ibm for liquid.

LE-01 13 Reactor Core Thermal Power Uncertainty Revision 1I Exelein. Calculation Unit 1 6.0 METHOD OF ANALYSIS 6.1 METHODOLOGY The methodology used to calculate Section 6 is based on CC-MA-103-2001, "Setpoint Methodology for Peach Bottom Power Station and Limerick Generating Station" (Ref. 4.1.1).

These are non-safety-related indication loops, but the indication is used to calculate Core Thermal Power, which is a licensing limit. This analysis will use the Square Root of the Sum of the Squares (SRSS) methodology for combining the random and independent uncertainties. The dependent uncertainties will be combined according to their dependency relationships and biases will be algebraically summed in accordance with the Reference 4.1.1. The level of confidence for each uncertainty will be normalized to a 2a confidence level.

6.2 CORE THERMAL POWER (CTP) CALCULATION:

The process computer provides a calculation of the CTP based on a system heat balance, where CTP is the difference between the energy leaving the system and the energy input into the system from energy sources external to the core. The process computer steady state reactor heat balance equation is based on a summation of all heat sources raising the inlet feedwater and other cold water to steam exiting the pressure vessel. Figure 5-1 shows the Limerick heat balance control volume.

Figure 5-1, Limerick Heat Balance Control Volume Diagram Page 26 of 94

LE-0113 Reactor Core Thermal Power Uncertainty Revision I

_Calculation Unit 1 CTP = Energy out - Energy in (Equation 1)

Energy in = QFW-1N + QCRD-IN + QP (Equation 2)

Energy out = Qs.Fw + QOCRD-OUT + QRAD + QRWCU (Equation 3)

Where, CTP Core Thermal Power generated by nuclear fuel QFW-IN Energy of feedwater required to raise inlet FW to Steam Energy of CRD purge water and recirculation pump seal purge water QCRO-IN going to feedwater Qp Heat added by the recirculation pumps QS-FW Energy of steam from feedwater supply QCRD-OUT Energy of CRD purge water and recirculation pump seal purge water going to steam QRAD Radiative heat losses from the reactor pressure vessel Heat removed by the RWCU system regenerative heat exchangers QRwcu (includes both a heat removal term and a heat additions term) 6.2.1 Energy In Each of the above heat contributors are individually evaluated as follows:

6.2.1.1 Energy of feedwater (QFw-IN) is equal to the feedwater mass flow rate (WFw) multiplied by the enthalpy of the water at the bulk temperature of the feedwater (hFw(TFw)) entering the reactor. Changes to the bulk temperature of the feedwater due to the influx of recirculation water and RWCU water are ignored because these mass flows represent less than 1 % of the total mass flow and the temperature change caused by their influx negligible.

QFW-IN = wFW- hF(TFW) (Equation 4) 6.2.1.2 Energy of Control Rod Drive purge water and recirculation pump seal purge water (QcRD.[N) is taken to be fixed at the enthalpy of water for a given temperature and pressure.

QCRO-IN = WCRD" hF(TcRo) (Equation 5) 6.2.1.3 Energy of recirculation pumps (Qp)

Energy of recirculation pumps (QF) is taken as the number of pump motors (n) multiplied by the efficiency of the pump motors (qrm) multiplied by the power of the pump motors (WE). This is a conservative value because the combined net energy of the two recirculation pump motors contributes to the energy of the recirculation water. This estimate is fixed relative to CTP because relatively large random variations in Qp will be negligible compared to QFW.

Qp= n, - WE (Equation 6)

__ _ _ _ Calculation Unit 1 6.2.2 Energy out 6.2.2.1 Energy of Steam Energy of steam from feedwater (Qs.Fw) is equal to the feedwater mass flow rate (WFw) multiplied by the enthalpy (hG(Ps)) of the steam (hG) at the steam dome pressure (Ps). The moisture carryover mass fraction is conservatively set to 0 (See Attachment 2).

Qs-Fw = WFW- hG(Ps) (Equation 7) 6.2.2.2 Energy of CRD Purge Water In a Boiling Water Reactor (BWR), the energy of CRD purge water and recirculation pump seal purge water going to steam (QCRO-OUT) is equal to the mass flow rate of control rod drive and recirculation pump seal purge water (WcRD) multiplied by its enthalpy. However, the Feedwater mass flow rate will makes up greater than 99 % of the steam mass flow rate; therefore, WCRD will be quantified as a fixed number because relatively large random variations in WCRD will be negligible in determining Qs.

QCRD-OUTr WCRD- hG(Ps) (Equation 8) 6.2.2.3 Energy of Reactor Pressure Vessel Radiative Heat Loss Energy of reactor pressure vessel radiative heat loss (QRAo) includes both heat loss due to thermal radiation as well as heat loss through convection. This value is fixed relative to CTP because relatively large random variations in ORAD will be negligible in determining Qs.

6.2.2.4 Energy of Reactor Water Clean-up Energy of reactor water clean up (QRwcu) is based on the net heat removed by the non-regenerative heat exchanges from the recirculated water stream bypassed from Recirculation Loop B to the RWCU.

The actual contribution to the heat removed from the reactor pressure vessel is negligible because the non-regenerative heat exchangers cool the stream going to the cleanup filters and demineralizers and the regenerative heat exchangers use the incoming stream to reheat the RWCU flow back up to the feedwater temperature. The mass flow rate is equal to the nominal pump flow rate the higher of Pump A or the combination of Pump B & C. The pump flow rate is fixed relative to CTP because relatively large random variations in QRwcu will be negligible in determining Qs. The net heat removed is equal to the mass flow rate (WRwcu) multiplied by difference of enthalpies across the RWCU.

QRWCU = WRWCU - [hF(TRPV) - hF(TFw)] (Equation 9) 6.2.3 Heat Balance Equation The reactor heat balance is based on the principle that heat input to the reactor water equals heat out.

Substituting Equations 2 and 3 into Equation 1 yields:

(QS-FW + QCRD-OUT + QPAD + QRWCU) = CTP + (QFW-IN + QCRD-IN + QP) (Equation 10)

Solving for CTP yields, CTP = (Qs-Fw + QCRD-OUT + QRAD + QRWCU) - (QFW-IN + QCRD-IN + QP)

- [WFW- hG(Ps) + WCRD hG(Ps) + QRAD + WRWCU - [hF(TRPv) - hF(TFw)l

Equation 13 is the form of the equation used by the Plant Process Computer (PPC) to calculate CTP (Reference 4.8.2). The CTP can now be expressed as a function of WFW, hG(Ps), QCRD-OUT, QRAD, QRWCU . hF(TFw), QCRD-IN , Qp.

CTP  : If (WFW, hG(Ps), QCRD-OUT, QRAD, QRWCU , hF(TFw), QCRD-IN, QP) (Equation 14)

Further simplification of Equation 14 can be made by setting variables with negligible input into the uncertainty of the CTP to constant values. The variables that have negligible contribution to the determination of the uncertainty of the heat from CTP are QCRD-OUT, QRAD, QRWCU, QCRD-IN, and Qp as discussed above (Sections 6.2.2.2, 6.2.2.3, 6.2.2.4, 6.2.1.2, and 6.2.1.3).

y = f(x1, x2 ,.... XN)

N= N Where, aIf ciaXi and ui(y) = I q- I U(Xi)

(Equation 17)

The standard uncertainty, uc, is multiplied by a coverage factor, k, which is equivalent to the number of standard deviations for a given confidence level toarrive at the measurement uncertainty U and the expected value of y, Y, is taken as y plus or minus the measurement uncertainty.

U= ku,,(y)and Y =y +/-U (Equation 18)

Per section 2.2.3, the maximum temperature of the water passing through the flow element is 582 *F and the normal temperature is 539 'F with the flow elements located just upstream of the RWCU Recirculation Pumps. Since the system temperature operation band is small, there is a minor change in the flow element expansion factor. The change is in order of 0.003 inches or less for the temperature range of 515 'F to 560 'F. Therefore the temperature effect on flow element expansion can be neglected.

During normal operations the temperature of the fluid passing through the flow element at the inlet of the RWCU system is approximately 535.3 *F.

Density is relatively constant at 1060 psig; however, for conservatism a variation of +/- 10 psig is used to show that the pressure effect is negligible even at four times the nominally specified transmitter reference accuracy of 0.25 %. The uncertainty in the density, cp(T,P),

The recirculation pump system consists of two parallel pumps that maintain forced circulation flow loops in the reactor core. The water originates in the core and returns to the core at a higher pressure. The work performed by the recirculation pumps includes the specific work of the pump plus the pump inefficiency. This energy can be estimated by measuring the power consumed by the pump motor and multiplying the pump motor power by the motor efficiency. The maximum design output of the recirculation motor M-G set is 7700 HP, which is monitored by the watts transducer. The 7700 HP is conservatively used in lieu of the motor 7500 HP rated in determining the recirculation pump heat uncertainty.

The difference between the input (actual pump power) and the output (ideal) pump power is the power lost to friction in the pump. The heat added to the pump is due to inefficiency.

Heat Added by Pump = ((1- r/V100 )"WA The calculation of the total recirculation pump heat input, Qp, is taken from Equation 6 (Section 6.2.1.3).

The manufacturer specifies the [/O module operating humidity limits between 0 and 95 % RH (Section 2.4.4). The I/O module is located in the Control Room 533, where humidity may vary from 50 to 90 %

RH (Reference 4.4.2). Humidity errors are set to zero because they are considered to be included within the reference accuracy specification under these conditions. (Section 3.2) e2H = 0 7.6.3.5 Recirculation Pump Motor Watt Transducer PPC I/O Module Radiation Error (e2R)

No radiation errors are specified in the manufacturer's specifications. The instrument is located in the Control Room 533, a mild environment (Section 4.4.2). Therefore, it is reasonable to consider the normal radiation effect as being included in the reference accuracy. Therefore, e2R = 0 7.6.3.6 Recirculation Pump Motor Watt Transducer PPC I/O Module Seismic Error (e2S)

No seismic effect errors are specified in the manufacturer's specifications. A seismic event defines a particular type of accident condition. Therefore, there is no seismic error for normal operating conditions (Section 3.5).

e2S = 0 7.6.3.7 Recirculation Pump Motor Watt Transducer PPC I/O Module Static Pressure Offset Error (e2SP)

The determination of total CTP uncertainty is sensitive to two measured parameters, feedwater mass flow rate measurement uncertainty and feedwater temperature measurement uncertainty.

8.0 CONCLUSION

S The total uncertainty associated with reactor thermal power (heat balance) calculation performed by the Plant Process Computer is 10.914 MWTH or 0.310 % of the MUR rated reactor thermal power limit of 3515 MWTH. This is a 2o value.

Dear Customer:

This letter is intended to eliminate any confusion that may have arisen as a result of the reference message from Grand Gulf. The message was concerned with statistical variation associated with published performance variables and how the variation relates to the published specifications in Rosemount Nuclear Instruments, lnc.(RNII) pressure transmitter m'oiels 1152, 1153 Series B;.

1153 Series 0, It 54 and 1154 Series H. According to our understanding, the performance variables ofpriinary concern are those discussed in GE Instrument Selpoint Methodology document NEDC 31336, namely I. Reference Accuracy

2. Ambient Teltlictature Effect

3. Overpressure Effect

4. Static Pressure Effects

5. Power Supply Effect It is RNII's undcrstantding that GE and the NRC have accepted the methodology of using transmilter testing to insure specifications are met as a basis for confirming specifications are

+3o. The conclusions we draw regarding specifications being +3a are based on manufacturing testing and screening, final assembly acceptance testing, periodic (e.g., every 3 months) audit testing oftransaiitter samples and limited statistical analysis. Please note that all performance specifications are based ott zero-basced ranges under rcifrence conditions. Finally, we wish to make clear that no inferences are made with respect to confidence levels associated with any speci ication.

I. Reference Accuracy-.

All (100%) RNII transmtitters, including models I152, 1153 Series B, 1153 Series D, 1154 and 1154 Series H, are tested to verify accuracy to+0.25% of span at 0%, 20%, 40%, 60%,

80% and 100% ofspan. Therefore, the reference accuracy published in our specifications is considered 43o.

2. Ambient Temperature Effect All (100%) amiplifier boards are tested for compliance with their temperature effect specifications prior to final assembly. All sensor modules, with the exception of model 1154, are temperature compensated to assure compliance with their temperature effect specifications. All (100%) model 1154, model 1154 Series H and model 1153 gage and absolute pressure transmitters are tested following final assembly to verify compliance with specification. Additionally, a review of audit test data performed on final assemblies of

__ _ . Calculation Unit 1 conformance to specification. Therefore, the ambient temperature effect published in our specifications is cotnsidered ÷3a.

3. Overpressure Effect Testing of this variable is done at the module stage. All (100%) range 3 through 8 sensor modules are tested for compliance to specifications. We do not test range 9 or 10 modules for overpressure for safety reasons. However, design similarity permits us to conclude that statements made for ranges 3 through 8 would also apply to ranges 9 and 10. Therefore, the overpressure effect published in our specifications is considered +3o.

4. Static Pressure Effects All (100%) differential pressure sensor modules are tested for compliance with static pressure zero errors. Additionally, Models 1153 and I 15,4 Ranges 3, 6,7 and Sare 100% tested after final assembly for added assurance of specification compliance. Audit testing performed on ranges 4 and 5 have shown compliance to the specificatjon. Therefore, static pressure effects published in our specifications are considered +3a.

5. Puwer Supply Effect leslitig for conformance to this speciftiction is pcrfoitred on all (ransitittcrs undergoing s"ample (Iudit) testing. This vat iable has historically exhibiled extremcly small performance errors and small standard deviation (essentially a mean error of zero with a standard deviation typically less than 10% of the specitication). All transmitters tested were found in compliance with the specification. "herelbre, power supply eflect published in our specilicalions is considered +/-3a.

Schematic D5-88114 Theory of Operation A2-5568 I. GENERAL DESCRIPTION The Potentiometer Card is a user card for the ANDS 5500 Data Acquisition System. It consists of a power supply and voltage reference, an output multiplexer and four identical signal conditioning channels. There are two 44-pin edge-card connectors (male) on the PC board, one is connected internally to the system and the other is for user connection.

Each signal channel consists of an excitation output section and a signal input section. The latter can be preset to accept a variety of valtage ranges and types via jumpers. It provides a DC voltage to, and permits low frequency and DC measurement of the signals from, appropriate external devices such as piezoelectric accelerometers.

LE-0113 "M Reactor Core Thermal Power Uncertainty Revision 1I t:Ixelon. Calculation Unit 1 Attachment 7 CTP Calculation Results Sensitivity Analysis The sensitivity of the calculation of core thermal power to variations in the energy terms is determined using estimated values for the energy out, energy in, and CTP.

Table A7-1 shows the results from Cases 1, 2 and 3. For this analysis, the error rate assumed for Qs is set equal to a predicted error for the measurement of feedwater flow.

In Case 1 and Case 2, the Qs error is kept the same; even though, the errors for the QRAD, QRWCU, QP, and QCRo terms are varied from 1 % to 19 % (29 % for Qcd). Case 1 and Case 2 show that CTP is relatively insensitive to the accuracy of the QRAD, QRWCU, Qp, and CCRD terms, when the CTP error is rounded to level of significance.

Case 3 varied the error rate assumed for Qs. A step change in the mass flow error rate of 0.01 % (from 0.31 %

to 0.32 %) was found necessary to change the CTP error by 0.02 % (a change of 1 MW from 17 MWtto 18 MWt and 0.500 % to 0.520 %).

The step change error rate was calculated to determine how fine the parameters used to calculate Qs and QFW need to be to effect the results. Parameter changes that would result in changes in the parameter's overall error rate less than 0.02 % were found to be negligible. Small variations in the flow measurement uncertainty were found to affect the CTP uncertainty.

For example, CTP is the difference between the energy leaving the reactor and the energy put into the reactor from other sources outside of the core. The enthalpy of saturated water varies with changes in pressure. For every 1 % change in pressure, the enthalpy of saturated water vapor (and by inference the energy of the flow) between 800 and 1,300 psig will vary by an average of 0.03 %. This change in enthalpy is less than the 0.04 %

found necessary to cause a significant change in the CTP error rate. Thus, CTP can be said to be tolerant of the steam dome pressure measurement error specified the pressure measurement loop is shown to be accurate to about -10 psig, which is approximately 1 % of the maximum allowable steam dome pressure.

_ __ __ o___ Calculation Unit 1 Attachment 8 Derivation of the relationship between flow, AP, and density A8-1 Basic Flow Equation Given that the basic flow equation (Reference A8.3-1) applicable to orifice plates, flow nozzles, and venturis is Q C 1 A , where C is a constant (Equation A8-1).

Then the relationship between flow (Q) and differential pressure (AP) and density (p) can be derived.

A8-1.1. Relationship between Q. AP and D For constant density, the flow can be shown to vary with the square root of AP such that, 0,1 _A' 1.

Q2 Al'2 (Equation A8-2)

If the variation around some nominal flow, Q0, is equal to some known uncertainty, a 1, then Q1 = Qo * (10 - 1 )and Q2 = Qo *(1+ al) (Equation A8-3)

Similarly, if the variation around some nominal differential pressure, AP0, is equal to some unknown AP uncertainty, ax, then AP1 = Po * (1 - ax )and AP2 = Po * (1 + 7x) (Equation A8-4a)

For constant AP, if the variation around some nominal density, PO, is equal to some unknown p uncertainty, oT,then P1 = Po *(1 - o-x)and P2 = Po *(1 + Gx) (Equation A8-4b)

These values can be substituted into Equation A8-2 and the equations manipulated to solve for a,.

Table A8-1 shows the relationship between the uncertainties in pressure or density, a(, and the uncertainty in flow, a1, to be essentially linear with a constant of proportionality equal to 2, see A8-11.2, provided a* is small, which is taken to be less than or equal to 15 %.

Thus for small flow uncertainties, small a1 , Equation A8-9 can be simplified as a linear function f(al),

Equation A8-10, which says the uncertainty in differential pressure or the uncertainty in density is approximately equal to 2 times the flow uncertainty. The inverse is also true; given a differential pressure or density uncertainty, the uncertainty of the flow is one-half the differential pressure or density uncertainty.

rx = n a1 , (Equation A8-10)

A8-1.2. The Limit of n The limit of the constant of proportionality, n, in Equation A8-10 as c0 approaches zero is found to confirm that n can be considered as a constant within the range of a1 less than 15 % to 0.

SCOPE I I This specification defines a Model 1153 Series B pressure transmitter with combined options N0016 - a stainless steel 1/2 - 14 NPT pipe plug installed in one of the conduit hubs, and N0037 - a 4-2OmA output signal with adjustable damping.

I1. DETAILS

1. The pipe plug is to be assembled on the nameplate/vent valve side of the transmitter. The plug will be sealed with thread sealant and torqued to 150 in.-lbs.

2. The standard "R" calibration and amplifier boards are replaced with the special damping calibration and amplifier boards.

III. SPECIFICATIONS Maximum damping for the electronics, measured at the 63% time constant is:

Maximum Damping Range 3 not applicable Range 4 1.2 seconds Range 5-9 0.8 seconds The damping electronics are not intended for the range 3 because the slower response Is not required for this transmitter pressure range.

IV. APPLICABILITY AND APPROVALS This specification is limited to the Model 1153 Series B with "R" electronics.

Qualification with the pipe plug was addressed in Rosemount Report 108026 (see paragraph 5.3.1). Qualification of the damping option was addressed in CLASS IE USAGE 1Iosen _n.,t.MINNEAPOLS. mINNESOTA OILmBy ATE Hidbad 11/
