Calculation Title: Main Steam Pressure Uncertainty and Scaling Calculation I

1.0 ORlECTIN'U

This calculation computes the loop uncertainties associated with the indication, alarm, andsafeguards actuation setpoints provided by the Main Steam Line Pressure instrumentation loops.The instrumentation also provides an input into the Emergency Response Facility InformationSystem (ERFIS). The uncertainties at the input to ERFIS are calculated. The uncertainty associatedwith the pressure input signal for safeguards actuation signal as a result of High Steam Flowcoincident with Low Main Steam Line Pressure is determined. The uncertainty associated withHigh Steam Line Differential Pressure is determined. This is used as an input to safeguardsactuation. The Reactor Turbine Generator Control Board (RTGB) indication uncertainty isdetermined. This calculation also determines the Allowable Value (AV) for the safeguardsinitiation setpoint.

Uncertainties associated with the control functions provided by Main Steam Line Pressure arc notcalculated.

The instrument loops contain the components in Section 3.0 and are addressed in this calculation.

2.0 FTTNC(TONAT. DESCRIP1TON

The Main Steam Line Pressure channels are used to provide indication of Main Steam LinePressure on the RTGB during normal and accident conditions, an input for Safeguards actuation,and Main Steam Flow density compensation.

5.0 INPIITS AND ASSI1M"TIONS

5.1 The accuracy of a typical test resistor is on the order of ± 0.01%. Therefore, the testresistors used during calibration are assumed to have a negligible impact on the overalluncertainty calculation.

5.2 Per Reference 4.7.5, the ambient temperature in the Control Room varies from 70cF to77V during operation. The calibration temperature for the indicator is assumed to be600F. Therefore, a change in temperature of 170F (9.4"C) is used to compute the indicatortemperature effect.

5.3 Per Reference 4.7.4, the pressure transmitters are located in the Turbine Building. TheTurbine Building is an open structure. Because the transmitters are located inthermostatically controlled enclosures, the minimum temperature used to compute thetransmitter temperature effect is assumed to be 33 TF. The maximum temperature is107'F. (Reference 4.7.1 provides the information and references the U.S. Department ofCommerce, Environmental Data Service, "Climatic Atlas of the United States" June1968 as a source).

5.4 Per Reference 4.6.1, reference accuracy typically includes the effects of linearity,hysteresis, and repeatability. The indicator reference accuracy is given in Reference 4.4.2is assumed to include the effects of linearity, hysteresis, and repeatability.

5.5 Per Reference 4.7.5, the maximum temperature of the Hagan Room is 820F. PerReference 4.6.1, the racks may experience an additional 100F heat rise during operation.The ambient temperature at the time of calibration is assumed to be 500F. Therefore, achange in temperature of 420F is used to compute the temperature effect associated withthe rack components.

5.6 The Westinghouse 3110552-000 Computer Signal Conditioner is a high precisionresistor. Based on the high accuracy of the resistor, the resistor has a negligible impacton the overall loop uncertainty computation.

5.7 Per References 4.5.1 through 4.5.9, the IN module is calibrated as part of a string. PerReference 4.4.1, the IN module is a resistor. Resistors typically experience negligibledrift. Therefore, any resistor drift throughout the fuel cycle is negligible and is accountedfor during the string calibration.

5.8 The transmitters are seismically qualified by Rosemount. Per Attachment B, the postseismic effect of the transmitter is ± 0.25% of Span.

5.9 As noted on the Instrument Identification Table in Section 3.0, there are two types ofNUS isolators used in the instrument loops addressed by this calculation. Theperformance specifications of these similar devices are almost identical, but they containminor differences. To facilitate this calculation, the isolators are considered to be thesame and, in every case, the more conservative of specific device uncertainty terms isused to determine overall device uncertainty for the isolators.

5.lOThe temperature of the pure water used to calibrate the transmitters is assumed to be900F.

5.11 The process pressure at 6% Steam Generator Tube Plugging is used. This value isobtained from Reference 4.2.5.

Per Section 9.1 of this calculation, the transmitter is located 20.03 fcct below thecondensate pot. A sensing line fill fluid of pure water at 900F per Section 5.10 and aprocess pressure of 800.5 psia per Reference 4.2.5 is used to calculate the hydrostatic headon the transmitter. Per Input and Assumption 5.3 the maximum ambient temperature is1070F. The sensing lines are insulated against freezing and the transmitters are enclosed ina temperature controlled housing. Therefore the minimum temperature is 33 0F. Theprocess measurement effect due to changes in sensing line fill fluid density (PME) is a onedirectional bias calculated with the following equation:

Per Reference 4.5.10, the transmitter is calibrated using a Digital Multimeter (DMM),which reads a 1-5 Vdc (4-20 mAdc signal across a precision 250 Q resistor) and a PressureStandard (PS). The transmitter MTE uncertainty is the combined uncertainty of these twodevices. Device uncertainties must be converted to common units (% Span) before theycan be combined.

The accuracy of the specified DMM is ± 0.034% of reading plus 2 digits. This is convertedto % Span as follows:

DMM Uncertainty = ±(5 Vdc * 0.034%) + 0.0002 - + 0.043% Span

Per Reference 4.4.1, the NUS comparator temperature effect is given as ±0.04% Span perIOC change in temperature from the temperature at the time of calibration, and notemperature effect is specified for the Hagan comparator. Per Reference 4.6.1, if notemperature effect is specified for a device, a default value of ±0.50% Span may be used forthe temperature effect. Per Design Input 5.5, a change in temperature of 420 F (23.330 C) isused to compute the comparator temperature effect. Therefore,

The function of this setpoint is to provide input to the Safety Injection and Main Steam Lineisolation logic. This results in an isolation of the Main Steam System and Safety Injectionfor a condition of High Steam Line Differential Pressure. This occurs if the Steam Headerand Main Steam Line Pressures are different due to a steam line rupture on the SteamGenerator side of the Main Steam Isolation Valves. During normal operations, a 20 to 30psig differential exists between the Main Steam Line and the Steam Header. Per Reference4.2.3, safety analyses assume a setpoint value of 100 psig ± 60 psig with satisfactory results.This provides two analytical limit values for evaluation; 40 psig and 160 psig. The logiccircuitry functions by sensing when Main Steam Line Pressure increases above SteamHeader Pressure to yield the predetermined (setpoint) differential of 100 psig. Therefore,this is a setpoint actuated by an increasing process signal, so negative uncertainties are usedwhen evaluating the adequacy of the setpoints / allowable values.

Per Reference 4.5.11, the MainSteam Pressure transmitters are calibrated 0 to 1400 psig (4-2OmAdc) 1-5Vdc. Therefore,the span of each loop is 1400 psig.

Per Reference 4.7.6 and field measurements, the pressure transmitters are located 20.03 feetbelow the instrument tap. Per Reference 4.2.4, the nominal post power up-rate steam headerpressure is 800.5 psia. A sensing line fill fluid of pure water at 900F and 800.5 psia is usedto determine the hydrostatic head on the transmitter using the following equation:

Hydrostatic Head = ph144

Hydrostatic Head = 8.66psi

Where,h = height of sensing line

= 20.03 feet

p = sensing line fill fluid density used for scaling= 62.26799 Ibmnft3 @ 90°F, 800.5 psia

NOTE: The factor 144 is used to convert from lbf/ft to lbf/in2. At standard gravity,Ibm may be replaced with lbf.

The hydrostatic head is converted to voltage units as follow:

Subject: Long Term Drift Test 4LTDT) Results for NUS modules - Final Report, ExecutiveSummary

Dear Mr. Pat Hartig:

NUS Instruments (NUSI), undertook a research and development project in 1996 to re-engineer instrumentation for use as replacements for the obsolete Hagan line of nuclearplant instrumentation. The NUSI replacement modules were designed originally usingspecifications written by Public Service Electric and Gas (PSE&G). The final specificationsincorporated both original Hagan published specifications and new or additional plant-specific requirements. The final agreed upon specification formed the design basis for theNUS Instruments 800 Series product line that has been sold to many nuclear plantsincluding Salem, H.B. Robinson, Turkey Point and Diablo Canyon.

NUSI has been requested by FENOC to supply instrumentation drift specifications for the800 Series modules. We understand that these numbers are to be used to determinerequirements for plant calibration cycles for these modules. The calibration cycle may beextended if it can be shown that the drift of the replacement modules is below specifiedcriteria. This change would result in a significant savings in plant maintenance costs.

NUSI was contracted by PSE&G to conduct a 36-month Long Term Drift Test (LTDT).This test was conducted on four classes of modules with four units of each type for atotal of sixteen modules undergoing the test. The four classes of modules consisted offour Dual Alarm Modules (DAM), four One-channel Analog Isolators (OCA), four RTDAmplifiers (RTD), and four Four-Channel Summing Modules (SUM). A loop of instrumentswas also tested to determine overall loop drift.

NUSI is currently in the process of preparing the final test report which will provide greaterdetails about the test modules and fixture, test procedure and processes, data andsampling intervals, analysis and plots showing the data trends. This data represents over26,000 hours of testing and over 24,000 individual data measurements. NUSI can makeavailable upon request the Excel 97 workbook that provides the data, analysis, andnecessary graphing tools. This report will be available October 31, 2001.

It is also worth noting that several utilities have been conducting their own independentlong term drift tests of a instruments installed in their loops. They can independentlysupport that the NUSI 800 Series instruments meet or exceed the long term driftspecification.

From: James [email protected]: Tuesday, January 15,2002 11:54 AMTo: [email protected].: Series SC993 and Series 800 Isolators

Series SC993 isolators were manufactured by us under the names of EnergyIncorporated, El Electronics, El Systems and El International. They are an earlyversion of stand alone isolator intended for electrical isolation of the inputs from theoutputs. They were encapsulated and had terminal blocks for connection of power,inputs and outputs. They were single channel devices. The power supply used was anearly type of switching power supply that is no longer manufactured. The isolationcircuitry was basically the same as is currently used in all NUSI isolators and many ofour other instrumentation devices. The actual isolation element, the Burr-Brown 3656is identical to that used today. All devices manufactured then underwent dielectricwithstand testing of 3000 Vdc and at 2500 Vac to ensure their readiness to isolate apotential fault. They also were 100% functional tested. The units were encapsulatedwith an epoxy and aluminum oxide based compound that made them impervious tovirtually all environmental concerns and seismically were considered a "brick". Theywere qualified simply by their mounting constraints. Internal heating was not a concernas the potting compound used had a very high thermal conductivity. Outputs andpower were fused on the top surface of the aluminum chassis. Span and zeroadjustments were also mounted there. The device is simple internally and externally. Ithas many years of reliable performance at several nuclear plants with little or no unduemaintenance issues. The only know life issue is the power supplies used (then andnow) have aluminum electrolytic capacitors with know life characteristics of abouttwenty years. Pots should not be adjusted unless the unit is out of tolerance to reducethe wear and tear on them. If a typical maintenance cycle is used, the devices willeasily achieve their twenty year life expectancy with no problems. The limited lifecharacteristics will not affect their isolation specifications in any way. These deviceshad only limited surge protection circuitry (on the inputs) included. Outputs and powerports may be susceptible to damage from surges but will not pass this to the inputs.

NUS Instruments currently manufactures devices that are form, fit and functionreplacements for the SC993 series. These are the SCA101 devices in the SCA100series of isolators. These devices differ from the SC993 in the power supply used andthat the chassis is 1/16' deeper than the older versions. These devices have surgesuppression circuitry and have been surge tested on all ports. Fault testing and otherisolation parameter testing has been completed on these devices. All otherparameters, including the circuitry and elements used do not differ from the SC993series.

Project Title:


Series 800 devices were manufactured by us under the names Haliburton NUS,Haliburton NUS Environmental Corp., NUS Corp. and NUS Instruments. They are stillin production. These devices include FCA, OCA and FIA versions with seriesdesignations 800 and 801. The only differences are the number of channels loaded,test jack size and LED power indicator colors. These devices all use modern switchingpower supplies in varying numbers dependent upon the output ranges and isolatortypes. FIA isolators have a separate power supply for each channel to give the outputsisolated commons. The circuit is operationally the same as earlier types and the actualisolation element is still the Burr-Brown 3656. These devices have undergone completeisolation type testing for dielectric withstand of 3000 Vdc and 1000 Vac, and mostproduction units are tested to these values. The devices under went fault type testingto 480 Vac and 140 Vdc applied to all ports in the FIA800 series. Shorts, opens andinter-channel effects have also all been type tested. The devices have also been testedfor surge withstand using the waveform specified in IEEE 472. All production units are100% functionally tested prior to shipment. The chassis and electronics have beenseismically proof tested for operation before, during and after the defined DBE with noanomalies. These devices use an aluminum chassis that is intended for rackmounting. The internals are accessible and passive air flow through the chassisremoves internally generated heat. Outputs are fused on the rear and power is fusedon the front of the devices. Span and zero adjustments are located on the front plate ofthe devices. These devices have the same life characteristics in the power suppliesused but since they are not potted, the power supplies may be replaced allowing for theisolators to have 40 year life expectancies.

All devices are manufactured using a 10CFR50 appendix B quality assurance programand are provided with 1 OCFR part 21 traceability as basic components.
