SUBJECT:
Davis-Besse Nuclear Power Station, Unit 1 Docket No. 50-346, License No. NPF-3 Reactor Protection System High Flux Trip Setpoint Calculation (TAC No. MD5240)
By letter dated April 12, 2007, the FirstEnergy Nuclear Operating Company (FENOC) submitted an amendment request for Davis-Besse Nuclear Power Station Unit No. 1 (DBNPS) for Measurement Uncertainty Recapture Power Uprate. On July 25, 2007, the Nuclear Regulatory Commission (NRC) staff submitted a request for additional information (RAI) concerning the application. By letter dated September 18, 2007, FENOC provided responses to the RAI, which included a commitment to make the Reactor Protection System High Flux Trip setpoint calculation available for NRC staff review by November 1, 2007. On November 8, 2007, FENOC informed the NRC that FENOC would not be able to produce the calculation until January 2008.
The Reactor Protection System High Flux Trip setpoint calculation has been revised and is provided in the Enclosure. Attachments 5-8 of the calculation are not included in the Enclosure. These Attachments contain spreadsheet formulas that were used for design verification of the information contained in Attachments 1-3. Additionally, the Supporting Documents referenced in the Table of Contents are primarily administrative documents used for review and approval of the setpoint calculations. The Supporting Documents are not included in the Enclosure.
Specific sections of interest include Section 4.5, "As-Left Tolerances (ALT)," Section 4.7, "Limiting Trip Setpoint Calculations," Section 4.8, "Nominal Trip Setpoint Calculations," and Section 4.9, "As-Found Tolerances." As discussed in Section 1.2.2, the calculation contains other setpoints in addition to the High Flux Trip Setpoint. These other setpoints are not relevant to the Measurement Uncertainty Recapture Power Uprate but are included in this correspondence as part of the calculation.

SUMMARY
C-ICE-058.01-008 600387414
- VENDOR CALCULATION NO. N/A OBJECTIVE OR PURPOSE:
The purpose of this calculation is to determine the field setpoints for the Reactor Protection System (RPS) Reactor High Flux, Power/Imbalance/Flow and Power/Pumps Trip functions. This includes calculated drift for the associated equipment consistent with the time interval allowed in the Technical Specifications. The As-Found and As-Left equipment performance values are also derived. See Section 1.1 for the affected bistable equipment identification numbers.
SCOPE OF CALCULATION/REVISION:
This revision is needed to support License Amendment Request 05-0007 (Serial 3198) "License Amendment Application for Measurement Uncertainty Recapture Power Uprate" (DIN 55). Revision 04 incorporates a second Allowable Value (AV) for the RPS High Flux Trip. This second AV shall be used when the Ultrasonic Flow Meter instrumentation is inoperable or not used in the performance of the daily heat balance (DIN 55 and 56). Also, former Attachments are being replaced with more current component drift evaluations.
Consistent with Serial 3198, As-Found and As-Left values used for evaluating equipment performance will be derived.
SUMMARY
OF RESULTS/CONCLUSIONS:
The field setpoints for the Reactor Protection System (RPS) Reactor High Flux, Power/Imbalance/Flow and Power/Pumps Trip functions are as follows:

C-ICE-058-01-008 ANALYSIS METHODOLOGY ISA-67.04.01-2000 (DIN 8) develops a basis for establishing setpoints for nuclear safety-related instrumentation. This document was prepared by the Instrument Society of America (ISA) with a goal of providing uniformity in the field of instrumentation. ISA-RP67.04.02-2000 (DIN 9) presents guidelines and examples of methods for the implementation of ISA-67.04.01-2000. Regulatory Guide 1.105 (DIN 6) endorses the use of the 1994 version of the ISA standard as an acceptable method for determining safety-related setpoints. The 2000 version of the ISA standard is identical to the 1994 version with respect to the RG 1.105 technical review issues. While RG 1.105 is specifically applicable to safety-related setpoints, it also recognizes that the standard "is also appropriate for non-safety system instrumentation for maintaining design limits described in the Technical Specifications".
Several methods for determining the Allowable Value (AV) have been developed and are presently in use.
This calculation utilizes Method 1 from ISA-RP67.04.02-2000, Section 7.3. "Method 1" determines the AV by calculating the instrument channel uncertainties that are NOT "tested" during the Channel Functional testing and includes those uncertainties between the Analytical Limit and the AV. All other "tested" uncertainties, including drift of control room cabinet equipment, calibration uncertainties, and uncertainties observed during normal operation are included between the AV and the Limiting Trip Setpoint. Those uncertainties that are NOT "tested" include, but are not limited to, drift of non-control room cabinet equipment such as transmitters, other uncertainties of the equipment that would be tested on a 24 month cycle, and other effects that are not testable by a surveillance test such as DBE effects.
The Limiting Trip Setpoint (LTSP) will be calculated by combining the computed sum of several terms with the Technical Specification Allowable Value. These terms include the As-Left Tolerance (which includes accuracy and Calibration Uncertainty) and Drift Allowance (see Sections 4.5 and 4.4). In addition, margin will be included to establish a Nominal Trip Setpoint (Section 4.8). The sum may be computed by the use of the Square Root Sum of the Squares (SRSS) method (DIN 9), by a simple arithmetic addition of terms or by a combination of both. SRSS is an accepted method for summing independent uncertainties/inaccuracies associated with an instrument setpoint calculation. Arithmetic summation yields a larger number and is used to sum terms which are dependent on the same uncertainty source or as desired.
The As-Left Tolerance is an allowance made for acceptance of the calibration of the instrument string.
The As-Left Tolerance is controlled and declared here, and implemented by the calibration/functional test procedures (DIN 40, 41, 42, and 43).
The As-Found tolerance is an allowance made to determine if the instrument string is exhibiting expected behaviors between calibrations. The As-Found Tolerance is controlled and declared here and implemented by the calibration/functional test procedures (DIN 40, 41, 42, and 43).
Per Serial 3198 (LAR 05-0007), Measurement Uncertainty Recapture Power Uprate, the shift of the RPS High Flux instrument string setpoint shall be evaluated and documented in the surveillance test procedures. The As-Found setpoint will be subtracted from the As-Left setpoint from the previous surveillance and the result shall be less than or equal to the As-Found Acceptance Criteria Band. This comparison shall be contained and documented in the RPS Surveillance Procedures (DIN 40, 41, 42, and 43). The As-Found Acceptance Criteria Band is calculated in Section 4.9.
Drift Allowance will be calculated for 3 month string drift for compliance with the required 92 day Functional testing of the RPS Functional Units. Drift allowances are calculated in Attachments 1, 2, and 3.
Calibration Uncertainty is the inaccuracy of the calibration device and/or reference standard, which in this analysis is a digital multimeter and/or precision resistor. The devices used are declared and controlled in
Page 2 FMstne CALCULATION COMPUTATION NOP-CC-3002-Ql Rev. 03 CALCULATION NO.: REVISION:
C-lCE-058.01-008 1 4 this calculation. Procedures and Data Packages shall maintain the device inaccuracy to be consistent with or better than the value used in this calculation.
Conservative margin is included, as any setpoint calculation is just a documented use of a selected method to arrive at a best estimate of a field setpoint. Periodic channel functional testing validates the method used. Should a surveillance result in violation of the Technical Specification Limit an evaluation is required to determine that the Safety Limit was being preserved. The evaluation will determine if the problem affects safety and if it is caused by equipment malfunction, calibration method, measurement and test equipment or by an inadequate field setpoint methodology.

1.2 Functional Description/Design Basis 1.2.1 Background Discussion This calculation is developed in accordance with the Tier-1 requirements of NOP-CC-3002 (DIN 48);
therefore, information from previous revisions has been design verified.

C-ICE-058.01-008I 4 This calculation is not intended to include accident and abnormal conditions. Those are accounted for in determining the Technical Specification Allowable Values which are determined external to this calculation. See Section 1.1 for the affected bistable equipment identification numbers and Section 4.1 for all equipment associated with this calculation.
1.2.2 Reactor Protection System (RPS) Function (DIN 3 & 7)
The purpose of the RPS is to initiate a reactor trip when a sensed parameter (or group of parameters) exceeds a setpoint value indicating the approach of an unsafe condition. In this manner, the reactor core is protected from exceeding design limits and the Reactor Coolant System (RCS) is protected from high pressure.
The RPS consists of four identical protection channels which are redundant and independent. Each channel is served by its own independent sensors which are physically isolated from the sensors of the other protective channels. Each sensor supplies an input signal to one or more signal processing strings in the RPS channel. Each signal processing string terminates in a bistable which electronically compares the processed signal with trip setpoints. All bistable trip contacts are connected in series. In the normal untripped state, the contact associated with each bistable will be closed, thereby energizing the channel terminating relay.
Contacts from eight trip bistables are normally in series with the power supply to each of the protective channel trip relays. The trip bistables included are RCS high pressure, low pressure, pressure-temperature, power/imbalance/flow, high flux, power-pumps, high temperature, and containment vessel (CV) high pressure. The first three compare RC pressure with fixed high and low pressure setpoints and a pressure setpoint which is a function of RC outlet temperature. The second three compare the output of the power range neutron flux monitor related to the protective channel with the total RC flow and core imbalance, a fixed high power setpoint, and a high power setpoint which is a function of the pump configuration. The seventh trip bistable compares RC outlet temperature with a high temperature setpoint. The eighth compares the CV pressure with a high pressure setpoint.
The trip functions of RPS which are affected by this calculation are as follows (See Section 4.1 for instrument string diagrams):
A. High Flux The High Flux trip function, Functional Unit 2 in Technical Specification Section 3/4.3.1, is also referred to as Overpower. For the remainder of the calculation, it will be referred to as High Flux.
Each RPS channel contains a two-section power range neutron flux detector. The signals from each half are summed to produce a total power signal. This power signal is sent to the high flux, power/pump, and power/imbalance/flow bistables. When the total power signal exceeds the high flux trip setpoint of the bistable, its relay contact will open, de-energizing (tripping) the channel terminating relay. During the high flux functional test, the power range test module sends two test signals, which represent power levels in the upper and lower half of the reactor core, to two linear amps. The outputs of the linear amps are then summed in the Sum/Diff amp and its resultant, representing total core power, is sent to the High Flux bistable (DIN 57, 58).
B. Power/Pumps The High Flux / Number of Reactor Coolant Pumps On trip function, Functional Unit 8 in Technical Specification Section 3/4.3.1, is also referred to as Power/Pumps For the remainder of the calculation, it will be referred to as Power/Pumps.

C-ICE-058.01-008 14 Reactor Coolant Pump (RCP) status (on-off) and information as to the loops in which pumps are operating, is monitored by pump monitors. The pump monitors provide an open or closed contact as the input to the RPS. The pump contact monitor module provides a variable signal which is a function of the number of running pumps and the loop in which they are running. This signal is used as a variable setpoint signal in the power/pumps bistable. If the total reactor power exceeds the power/pumps setpoint, as determined by the pump configuration, the bistable will cause its associated relay contact to open, de-energizing (tripping) the channel terminating relay. During functional tests, test signals are produced in the power range and contact monitor test modules. Similar to the high flux functional test, the power range test module sends two signals to two linear amps and then into one Sum/Diff amp. The contact monitor test module outputs contact logic, simulating Reactor Coolant Pump status, to the contact monitor module. The outputs from the Sum/Diff amp and the contact monitor are then compared in the Power/Pumps bistable (DIN 57 and 59).
C. Power/Imbalance/Flow The Flux / A Flux / Flow trip function, Functional Unit 4 in Technical Specification Section 3/4.3.1, is also referred to as Power/Imbalance/Flow. For the remainder of the calculation, it will be referred to as Power/imbalance/ Flow.
Each RPS channel receives two differential pressure signals (one from each reactor coolant loop) for flow.
The signals are developed by differential pressure transmitters that measure pressure drop across gentile tubes mounted in the two reactor coolant loops. The analog output of the transmitters is proportional to flow squared. The output is processed by a current to voltage (I/E) converter and is input to a square root extractor which converts the signal to one directly proportional to flow. The proportional flow signals from both RC loops are summed to produce a total RC flow signal in the buffer amplifier. Each RPS channel monitors reactor power imbalance. This is the difference between the power measured in the top half of the core and the power measured in the bottom half of the core by the two separate power range neutron flux detectors. The imbalance signal and the flow signal are combined in a Function Generator and the resultant function signal is compared with the total power signal in a bistable. The bistable will trip when the total reactor power signal exceeds the trip envelope limit in the Core Operating Limits Report (DIN 49).
When this bistable trips, its relay contact opens, de-energizing (tripping) the channel terminating relay.
During functional tests, test signals are produced in the power range test module and by two flow transmitter simulators. Similar to the high flux functional test, the power range test module sends two signals to two linear amps. The two linear amps output to a difference amp to determine power imbalance. The flow transmitter simulators, simulating flow in each hot leg, send current signals to two current-to-voltage converters, to two square root extractors, and are~then combined in a buffer amp. The resultants of the difference (power imbalance) and buffer amps (flow) are combined in the function generator. The output of the function generator is finally compared to total flux in the Power/Imbalance/Flow bistable (DIN 57, 58, 60, 61, and 62).
D. Design Requirements The RPS is classified as a "Q" quality system and this calculation is Nuclear Safety Related. The RPS is designed to maintain the capability to perform its protective function during and after an earthquake. The vessel containing the equipment will protect it from flood, lightning, and wind. The RPS cabinets are housed in the control room where they are protected against fire, explosion, and missiles. All sensors and cables are located to minimize damage caused by fire, explosion, or missiles. The redundancy of the system will satisfactorily operate under all conditions. The system cabinets provide protection against mechanical damage and spread of fires between RPS channels. All sensors, signal transmission circuits, and signal conditioning devices are designed to function in postulated deteriorated environments to which they may be subjected for the length of time required to provide the protective action (DIN 3).

These procedures also perform the Channel Calibration of the instruments, if required by the testing interval. This calculation evaluates the uncertainties associated with the Channel Functional test (92 days) for compliance with the Technical Specifications. Any uncertainty associated with Channel Calibration that is not bounded by the Channel Functional testing is included between the Analytical Limit and the Allowable Value. This calculation establishes the uncertainties between the Allowable Value and the trip setpoints. The Data Packages associated with the 92 day test, DB-MI-03057 QTR, DB-MI-03058 QTR, DB-MI-03059 QTR, and DB-MI-03060 QTR (DINs 44, 45, 46, and 47) compliment the above procedures.

C-ICE-058.01-008 4 4.3 Uncertainties 4.3.1 Component/String Accuracies The accuracies of the equipment included in this calculation are typically included between the Allowable Value and the Limiting Trip Setpoint in compliance with ISA-RP67.04.02 (DIN 9). However, they are included in Framatome calculation 32-1172392-03 (DIN 15), which calculates the uncertainties included between the Analytical Limit and the Allowable Value. Based on this, the accuracies will be included for the establishment of the As-Found and As-Left values, but will not be included as an accuracy value in establishing the Limiting Trip Setpoint. The only effects to be considered in this calculation are the drift and the As-Left values (including accuracies and calibration uncertainties) for establishment of the Limiting Trip Setpoint.
In some cases, the manufacturer has specified a "Typical" (smaller) and a "Worst Case" (larger) accuracy uncertainty. Since the accuracy values being developed in this calculation are for the establishment of As-Found And As-Left values, using either the "Typical" or "Worst Case" accuracy will either increase or reduce the calculated uncertainty. When including the As-Left value in establishing the trip setpoint, larger or "Worst Case" accuracies would be conservative. When using the accuracy for establishing the As-Found and As-Left value for evaluation of the equipment performance, a smaller accuracy would be conservative. Since this calculation is establishing the As-Found and As-Left values, and the accuracy component is already included between the Analytical Limit and the Allowable Value by the Framatome /
AREVA calculations, the smaller accuracy values will be used in the calculations to ensure equipment performance is maintained at the highest level.
The effects of all other sources of instrument uncertainties are included in the Technical Specification Allowable Values which are determined external to this calculation. Framatome ANP / AREVA reports I calculations ANP-2514, 51-5012682-02, 32-1172392-03, 32-1257719-02, 86-5057366-003, 32-5057192-00, and 51-9004090-005 (DINs 4, 5, 15, 16, 18, 31, and 56) contain information pertinent to the calculation of those Allowable Values.

C-ICE-058.01-008I 4 4.3.2 Uncertainty Propagation Through Modules Per ISA-RP67.04-02-2000 (DIN 9, Section 6.3.1), if signal conditioning modules are used in the instrument channel, the propagation of uncertainties through the modules must be taken into account. Equations have been developed to determine the output uncertainties for several common types of signal conditioning modules and are presented in ISA-RP67.04-02-2000, Section 6.3.1 Table 1. The following
'equations are applicable to RPS modules included in this calculation:
Fixed Gain Amplifier erandom = K
- einput Square Root Extraction eranom = (einput) / (2
- input)11 Where:
K = multipliers of input signals (dimensionless gain) einput, einputl = uncertainty of input signal(s) input = input signal The summing amplifier equation from the ISA Recommended Practice is not included in this calculation since the Sum/Diff Amplifier acts as a fixed gain amplifier (gains are the same) with two inputs. Based on that, the fixed gain amplifier equation will be used with two linear amplifier inputs.
Since the accuracy values being developed in this calculation are for the establishment of As-Found and As-Left values, adjustable gains will either increase or reduce the calculated uncertainty. When including the As-Left value in establishing the trip setpoint, larger gains would be conservative. When using the gain for establishing the As-Found and As-Left value for evaluation of the equipment performance, a smaller gain would be conservative. Since the accuracy values are already included between the Analytical Limit and Allowable Value, a value smaller than the values currently included in the Data Packages (Dins 66, 67, 68, 69, 70, 71, 72, and 73) willbe used to reduce the As-Found and As-Left values to ensure equipment performance is maintained at the highest level.
The function generator is not included in the propagation of uncertainties. For the breakpoints on the sides (See Section 4.10.2), if beyond those points, a saturation value is added to the flow value to produce an output. Based on this, it does not modify the uncertainties input to the module similar to an amplifier.
Similarly, the breakpoints across the top will provide only the flow component as an output, thus not modifying the uncertainties from the flow input. The slopes are the only portion of the function generator that could cause the input uncertainties to be modified. The slope error is discussed in Section 4.5, which determines that a more conservative value than the calculated values will be used. Since the values calculated in Section 4.5, are for the development of an As-Left Tolerance, including additional uncertainty for the function generator slope, then reducing the value back to the same more conservative values is not necessary.
4.3.3 Calculation of String Accuracies The following section will calculate thestring accuracies for use in the As-Found and As-Left tolerance calculations. As stated above, the accuracies will not be specifically included in the Limiting Trip Setpoint development since the accuracies are already included in development of the Allowable Values.
4.3.3.1 High Flux String Accuracy As described in Section 1.2.2 and shown on Figure 1, the High Flux string consists of two signals that represent core power in the top and bottom halves of the core. The signals travel through two separate linear amps, are summed in a sum/diff amp, and the result (total power) is compared to a setpoint in a bistable. The uncertainties of the two signals from the linear amps are considered random and can be

High Flux Accuracy = SRSS (Sum/Diff Amp Input Uncertainty, Sum/Diff Amp Accuracy, Bistable Accuracy) % Span
= SRSS (0.035, 0.15, 0.15) % Span
= 0.215 % Span 4.3.3.2 Power/Pumps String Accuracy As described in Section 1.2.2 and shown on Figure 2, the Power/Pumps string consists of the High Flux String and input from the contact monitor. The contact monitor represents reactor coolant pump status (on or off). The output of the High Flux string and the contact monitor are compared to a setpoint in a bistable.
As input to the Power/Pumps string, the linear amplifier outputs are identical to the High Flux string.
Based on that, the Sum/Diff Amp Input Uncertainty from above will be used to represent the linear amplifiers. The total reference accuracy for the Power/Pumps string is:
Power/Pumps Accuracy = SRSS (Sum/Diff Amp Input Uncertainty, Sum/Diff Amp, Contact Monitor, Bistable) % Span
= SRSS (0.035, 0.15,0.3, 0.15) % Span
= 0.369 % Span 4.3.3.3 Power/Imbalance/Flow Accuracy As described in Section 1.2.2 and shown on Figures 3 and 4, the Power/Imbalance/Flow consists of numerous components. The High Flux String is utilized for total reactor power and power imbalance.
Power Imbalance is determined through ,the use of the two linear amp signals a~nd a scaled difference amp. The scaled difference amp determines if there are differences in power level between the top and bottom halves of the core then outputs the difference (imbalance) to the function generator. The gain of the scaled difference amp for channels 1 through 4 are 1.442, 1.490, 1.478, and 1.4995 per data packages RPS1NI1704, RPS2NI1704, RPS3NI1804, and RPS4NI1804 (DINs 66, 67, 68, and 69),
respectively. As described in Section 4.3.2, a smaller gain value of 1.25 will be used.
The Function Generator is provided with two accuracies for Breakpoint pairs 1 and 4, and 2 and 3. The calculation will calculate each independently for the Power/Imbalance (0.4%) and the Power/Flow (0.2%).
These breakpoints act independent of each other as described in Section 4.3.2. There is also an accuracy associated with the slope. The slope error will be addressed in Section 4.5.

Digital multimeters (DMM) are used for calibration of the RPS modules and precision resistors are also used during calibration of the RPS flow modules. The precision resistor and the DMM will be included for the Power/Imbalance/Flow portion (DIN 40, 41, 42, and 43). Only the DMM will be used for the other RPS strings.
Precision Resistor: 250 0 +/- 0.01% Span (or 0.001 Vdc on a 0-1OVdc scale)
DMM Accuracy is given as +/- 0.005% of Reading + 3 counts for 6 month calibration interval and 20 Vdc Scale (DIN 20):
DMM Accuracy = 0.005% of Reading DMM Count Accuracy =3 (On 20 Vdc scale a count = 0.0001 Vdc)
Reading = 0-10 Vdc Maximum Accuracies given in % are divided by 100% to convert to decimal fraction.

- 0.0001)
= 0.0008 Vdc The DMM allowance is conservatively increased to 0.003 Vdc or 0.03% Span.
As the DMM uncertainty is conservatively increased, the calibration standard, i.e., the instrument used to calibrate the DMM will not be included in the calculation. Since the calibration standard is typically at least 4 times more accurate than the DMM, the conservative increase of the DMM uncertainty would bound the calibration standard uncertainty.
4.3.4.1 High Flux Calibration Uncertainties In surveillance procedures DB-MI-03057, DB-MI-03058, DB-MI-03059, and DB-MI-03060 (DINs 40, 41, 42, and 43), the linear amplifiers are calibrated with 2 digital multimeters each. The remainder of the high flux string is calibrated with 2 digital multimeters connected to the output of the linear amplifiers. The bistable trip is verified based on the linear amplifier outputs. The multimeters used for the calibrations could be the same devices for each of the linear amplifiers and the high flux string. If the multimeter is off in one direction, then the same effect would be contributed to each calibration. Based on that, the three sets of multimeter uncertainties will be considered to be dependent uncertainties and accounted for as such in the equation. The propagation of the uncertainties through the modules will be combined similar to the accuracies above. This results in:
Sum/Diff Amp Input CAL Uncertainty = K

Bistable calibration uncertainty. The total calibration uncertainty for the High Flux string is:
High Flux CAL Uncertainty = SRSS (Sum/Diff Amp Input CAL Uncertainty, Sum/Diff Amp /
Bistable CAL Uncertainty) % Span
= SRSS (0.0424, (DMM1 + DMM2) % Span
= SRSS (0.0424, (0.03 + 0.03) % Span
= 0.0735 % Span 4.3.4.2 Power to Pumps Calibration Uncertainties For the Power to Pumps trip, the value from the High Flux uncertainties for the Sum/Diff Amp Input CAL Uncertainty may be used since the same output from the Sum/Diff Amplifier is input to both the High Flux and Power to Pumps bistables. The remainder of the instrument string is calibrated with two DMMs at the output of the linear amplifiers. Since this is identical to the test configuration for the High Flux Trip, the same value will be used.

4.3.4.3 Power/Imbalance/Flow Calibration Uncertainties The Power/Imbalance/Flow will be broken into two strings similar to the function generator curve. The Power/Imbalance is protected by the sides of the function generator curve and the Power/Flow is protected by the top of the function generator curve. The Sum/Diff Amplifier Calibration Uncertainty described above is used as an input to the Power/Imbalance/Flow Bistable. This uncertainty will be identical to the uncertainties calculated above.
Sum/Diff Amp Input CAL Uncertainty = 0.0424 % Span The Difference Amplifier uses the input from the Linear Amplifiers and inverts one input, sums the two to create the difference and multiplies that value by the gain. The calibration uncertainty associate with that is:

The linear amplifier drift is included in calculation 32-1172392-03 (DIN 15). The calculated uncertainty values in that calculation are included between the Analytical Limit and the Allowable Value. Based on that, the drift for the linear amplifiers, although normally included between the Allowable Value and the trip setpoint, will not be included in this calculation. The calculated drift values for the remainders of the instrument strings are:
High Flux Bias: -0.000291 Vdc Random: 0.009346 Vdc Power to Pumps Bias: 0.000249 Vdc Random: 0.012871 Vdc Power/Imbalance/Flow Bias: -0.000094 Vdc Random: 0.008268 Vdc The worst case from above would be Power to Pumps with a summed, total of 0.013120. The Technical Specifications allow the three month surveillance period plus a 25% extension for total time to test. To correct for the extension, the 0.013120 volt value will be multiplied by 1.25. This yields 0.016400 Vdc. A conservative value of 0.018 Vdc will be used. As the drift analysis determined the drifts to be not normally distributed, the drift will be added in the As-Left Tolerance calculation instead of using the square root sum of the squares method.
Drift =0.018 Vdc Drift = (0.018 Vdc/ 10 Vdc) 125% Power
= 0.225% Power 4.5 As-Left Tolerances (ALT)
The As-Left Tolerance is controlled and declared here, and implemented by the calibration/functional test procedures and System Work Packages (DIN 40, 41, 42, 43, 44, 45, 46, and 47).
Per the TSTF Improved Technical Specification Traveler 493, (DIN 63, page 7) the As-Left tolerance must be calculated to include only uncertainties of reference accuracy, M&TE accuracy, and M&TE readability.
Regulatory Issue Summary (RIS) 2006-17 (DIN 62) page 5, states:
Additionally, the TSTF did not sufficiently address the NRC staff concern with the practice of using Nominal Setpoints (NSPs) for establishingthe test acceptancecriteria band for as-found instrument values. The NRC staff concern was that excessive changes in the Trip Setpoints (TSP) could go undetected and also that a high incidence of false detections could result from such a practice.
Subsequently, the NRC staff investigated the acceptabilityof basing operabilitydeterminationsfor as-found instrument values on NSP values. The NRC staff review concluded that if specific conditions are met, then the NRC staff would find a NSP-based assessmentof as-found values acceptable. Those conditions are: (1) the setting tolerance band is less than or equal to the square root of the sum of the squaresof reference accuracy, measurement and test equipment, and readabilityuncertainties;(2) the
F CALCULATION COMPUTATION F~ne IPag 18 NOP-CC-3002-01 Rev. 03 CALCULATION NO.: REVISION:
C-ICE-058.01-008I 4 setting tolerance is included in the total loop uncertainty,and (3) the pre-defined test acceptance criteria band for the as-found value includes either, the setting tolerance or the uncertaintiesassociated with the setting tolerance band, but not both of these.
As described above, the ALT is determined by using the RPS string accuracy calculation (Section 4.2.4) and adding the calibration uncertainty (Section 4.3.4). The values for the accuracy and calibration uncertainty are developed in % Span. They must be converted to % Power by multiplying the values by 1.25 (125%). As discussed in Section 4.4, the drifts will be added since they are not normally distributed.

= 0.750% Power As stated in Section 4.3.3.3, the slope accuracy will be included after establishing the As-Left Tolerances and the Breakpoint locations. Instead of using the calculated As-Left Tolerances, the smaller, more restrictive As-Left Tolerances currently in use in the surveillance procedures will be used. This is conservative, since using a smaller As-Left Tolerance ensures the setpoint will be continuously close to its nominal setpoint and poorly performing equipment will be readily detected. Based on this, adding additional uncertainty due to slope to the calculated values, then reducing .the ALT values to provide a more restrictive ALT is unnecessary. This is acceptable since the slope accuracy is already included between the Analytical Limit and the Allowable Value as documented in Framatome calculation 32-1257719-02 (DIN 16), Section 10. As stated above, the more restrictive As-Left Tolerance values currently used in surveillance procedures will be retained. Those ALT values are:
High Flux ALT: +/- 0.0875% Power Power/Pumps ALT: +/- 0.225% Power Power/Imbalance/Flow: Power/Imbalance ALT = +/- 0.15% Power Power/Flow ALT = +/- 0.5125% Power

Note: The TS Allowable Values shown above were determined for Cycle 9 and evaluated in this calculation as being more conservative than the current calculated TS Allowable Values from the Reload Report (DIN 4). See Section 4.10.2 for correlations between current Reload Report calculated values, Cycle 9 values, and field setpoints. Therefore, this calculation declares that Cycle 9 TS Allowable Values will be utilized as the basis for determination of Power/Imbalance/Flow field setpoints in this calculation. As a result, these are the TS Allowable Values to be published in the Core Operating Limits Report (Output DIN 49).
With this additional margin, future cycle analyses that impact the current values in the Reload Report, but that remain bounded by Cycle 9 TS Allowable Values, may not require field setpoint changes for Power/Imbalance/Flow. This calculation shall be updated each Cycle to document that the Cycle 9 values remain bounding, or modify the Tech Spec values accordingly.

C-ICE-058.01-008 4 4.9 As-Found Tolerances (AFT)
The following As-Found Tolerances account for the uncertainties associated with the As-Left Tolerance plus the Drift Allowance. This is consistent with the guidance in TSTF Improved Technical Specification Traveler 493, (DIN 63, page 7). Per the TSTF Improved Technical Specification Traveler 493, (DIN 63, page 7) the As-Found Tolerance must be calculated to include only uncertainties of reference accuracy, M&TE accuracy, M&TE readability, and drift or the combination of the As-Left Tolerance and drift. The latter approach will be used because using the string accuracies (Section 4.2.4) would allow the as-found setpoint to be non-conservative with respect to the Allowable Value. Using the ALT ensures that the Tech Spec Allowable Value is protected.
Any As-Found value that exceeds the As-Found Tolerance requires recalibration to within the As-Left Tolerance around the Nominal Trip Setpoint prior to return to service.
4.9.1 High Flux As-Found Tolerance r
The As-Found Acceptance Criteria Band is determined by taking the High Flux string As-Left Tolerance (Section 4.2.4) and drift. The equipment accuracies and calibration uncertainties are included in the As-Left Tolerance, so they will not be listed separately. During surveillance testing, the absolute value of the previous As-Left minus the current As-Found shall be less than or equal to the As-Found Acceptance Criteria Band. If outside the As-Found Acceptance Criteria Band, the equipment shall be recalibrated to within the As-Left Tolerance around the Nominal Trip Setpoint and evaluated to verify it is functioning as required prior to return to service.
previous As-Left - current As-Found 1 5 As-Found Acceptance Criteria Band This approach is consistent with the methodology contained in a similar RPS Technical Requirements Manual LCO 3.3.1.2 and ensures that the components are exhibiting expected behaviors. This method for determining compliance with the As-Found Acceptance Criteria Band shall be contained in the RPS Surveillance Procedures (DINs 40, 41, 42, and 43).

- 6. CONCLUSIONS The Nominal Trip Setpoints identified above are based on Allowable Values from Serial 3198 (DIN 55) and AREVA 51-9004090-005 (DIN 56) with the exception of the Allowable Values for Power/Imbalance/Flow which are based on the Reload Report (DIN 4). The methodology for determining the setpoints is in compliance with ISA 67.04 requirements. Additionally, the As-Left and As-Found Tolerances are calculated based on the Technical Specification Task Force (TSTF) Traveler 493 (DIN 62) and the NRC Regulatory Issue Summary (RIS) 2006-17 (DIN 61). The calculated values are identical to the current operating values and no operator burdens have been identified with the setpoints. Based on this, the acceptance criteria outlined in Section 3 have been met.

C-ICE-058.01-008 4 Attachment I - Drift Analysis for High Flux Analysis Methodology The method used to determine the drift for the bistables is to analyze the as-found as-left (AFAL) setpoint data of the subject instruments. The statistical analysis will be based on TR-103335-R1, "Guidelines for Instrument Calibration Extension Reduction Programs - Revision 1: Statistical Analysis of Instrument Calibration Data" (DIN 26), with the following clarifications:
- 1. The calibration data was taken during a functional check. The procedures from which the data was retrieved are:
- DB-MI-03057, RPS Channel 1 Calibration of High Flux, Power/Imbalance/Flow, Power/Pumps Trip Functions (Din 40) 0 DB-MI-03058, RPS Channel 2 Calibration of High Flux, Power/Imbalance/Flow, Power/Pumps Trip Functions (Din 41) 0 DB-MI-03059, RPS Channel 3 Calibration of High Flux, Power/Imbalance/Flow, Power/Pumps Trip Functions (Din 42)
- DB-MI-03060, RPS Channel 4 Calibration of High Flux, Power/Imbalance/Flow, Power/Pumps Trip Functions (Din 43)
The instrument was adjusted if the as-found data was outside the tolerance and, in some cases, was adjusted even when within the tolerance.
- 2. The three-month drift was calculated using the following formula for a time period for which no replacements were made to the instrument. If adjustments were made, these were factored into the formula as follows:
Di = AF - AFi. 92 + Adjustment(s)
Where:
D, = Drift for the time period AF = As-Found during current calibration check ALi 92 = As-Left of approximately 92 days previous
- 3. Since the duration (di) of the calculated three-month drift (Di) was not always comprised of the same number of days and the Technical Specification defines three months as 92 days, for all durations less than or equal to 92 days, the calculated three-month drift was corrected based on the following equation:
Dci = Di (92/di) ; where Dci is corrected drift If the duration was greater than 92 days, the value would be decreased if the above equation were used. For conservatism, the value collected during the surveillance test was used as the normalized data (i.e., no interpolation of data).
For durations that were less than 46 days (92/2) or greater than 115 days (92 x 1.25) the data was not used since it would not be reflective of the 92 day drift.
- 4. The data will be evaluated for outliers and for normality.

- 5. The tolerance interval will be calculated for a confidence level of 95% with 95% of the population contained within the tolerance interval (TI) using the following equation:
TI( 95/95 ) = xbar + ks Where, TI(gs/ 95) = Tolerance interval for 95%/95%
xbar = Sample mean k = Tolerance factor (95/95) s = Sample standard. deviation
- 6. The following equations will be used to determine the mean and standard deviation:
Mean = xbar = (7 Dc, ) N, where N = sample count, and I = 1 to N 2 12 Sample standard deviation = s = [(I/(N - 1)) ((1 (Da )2 ) - N (xbar) )] '

C-ICE-058.01-008I 4 T-Test - High Flux The T-Test determines if a data point is able to be considered an outlier from all other data. This is accomplished by finding the worst case value in either the positive or negative direction, subtracting the mean from that value, taking the absolute value of the results, and dividing the resulting value by the standard deviation. This gives a result of the number of standard deviations the value is away from the mean. If the value is determined to be greater than the "Critical Value", the data point may be considered an outlier and removed from the data if there is a basis for removal. If the data is removed, the T-Test is repeated with revised worst case value, mean, and standard deviation, until the worst case data point is either less than the Critical Value or has no basis for removal.
Max value from Table = 0.014071 Min value from Table = -0.020092 Critical value for T-Test with a sample size of 96 and a Upper 5% Significance = 3.21 Standard Dev = 0.004160 Mean= -0.000291 T-Test for Max value 0.014071 T-Test for Min value -0.020092 T-Test = 3.4523 T-Test = 4.7601 Because the T-Test for both the Max and the Min values is higher than the 3.21 value, .they could be considered outliers and excluded from the sample. Due to there being no basis for removal, they will not be excluded. No further tests for outliers are required.

C-ICE-058.01-008I 4 Normalcy Test - High Flux Using the Chi-squared test for normalcy results in: 47.64 based on groupings of bins below.
As there are 8 bins, a normal distributed data set would be below 8. Since it is above 8, the data is determined to be NOT normally distributed. Graphing the data results in a display of data that has a high kurtosis (middle peak) and 3 data values outside of 3 standard deviations. To graphically display the data, a series is established starting at the Mean and moving away from the Mean by the Standard Deviation.
The number of data sets in each series are determined to be able to plot a normalcy graph. The following table displays the series boundaries and the number of data sets in each series and compares that to the normal distribution value. Due to the high kurtosis and the 3 values that are more than 3 standard deviations away from the mean, the data will be considered to be NOT normally distributed and will be included as a bias in the calculation.

C-ICE-058.01-008I 4 Time Dependency Analysis - High Flux Time dependency analysis is used to determine if there is a correlation between the period between calibrations and the resulting change in setpoint. Each data point has been calculated along with the associated time duration between calibrations. Each of the data points used have been included in the plot below. As can be seen from the plot, there are no discernable indications that the drift is in any one direction based on a given time period. For example, if there were a significant number of data points in the positive region from the period of 100 - 150 days with no corresponding data points in the negative region, this would indicate a time dependency with respect to the drift. Since this, nor any other similar correlation is evident, it is concluded there is no time dependency to the drift.

C-ICE-058.01-008I 4 T-Test - PowerlPumps The T-Test determines if a data point is able to be considered an outlier from all other data. This is accomplished by finding the worst case value in either the positive or negative direction, subtracting the mean from that value, taking the absolute value of the results, and dividing the resulting value by the standard deviation. This gives a result of the number of standard deviations the value is away from the mean. If the value is determined to be greater than the "Critical Value" , the data point may be considered an outlier and removed from the data if there is a basis for removal. If the data is removed, the T-Test is repeated with revised worst case value, mean, and standard deviation, until the worst case data point is either less than the Critical Value or has no basis forremoval.
Max value from Table = 0.030000 Min value from Table = -0.020164 Critical value for T-Test with a sample size of 96 and a Upper 5% Significance 3.21 Standard Dev = 0.005772 Mean= 0.000249 T-Test for Max value 0.030000 T-Test for Min value -0.020164 T-Test = 5.1547 T-Test = 3.5368 Because the T-Test for the Min and Max values are higher than the 3.21 value, they could be considered outliers and excluded from the sample. Due to there being no basis for removal, they will not be excluded.
No further tests for outliers are required.

C-1CE-058.01-008 "I4 Normalcy Test - Power/Pumps Using the Chi-squared test for normalcy results in: 44.99 based on groupings of bins below.
As there are 8 bins, a normal distributed data set would be below 8. Since it is above 8, the data is determined to be NOT normally distributed. Graphing the data results in a display of data that has a high kurtosis (middle peak) and 3 data values outside of 3 standard deviations. To graphically display the data, a series is established starting at the Mean and moving away from the Mean by the Standard Deviation.
The number of data sets in each series are determined to be able to plot a normalcy graph. The following table displays the series boundaries and the number of data sets in each series and compares that to the normal distribution value. Due to the high kurtosis and the 3 values that are more than 3 standard deviations away from the mean, the data will be considered to be NOT normally distributed and will be included as a bias in the calculation.

C-ICE-058.01-008I 4 Time Dependency Analysis - Power/Pumps Time dependency analysis is used to determine if there is a correlation between the period between calibrations, and the resulting change in setpoint. Each data point has been calculated along with the associated time duration between calibrations. Each of the data points used have been included in the plot below. As can be seen from the plot, there are no discernable indications that the drift is in any one direction based on a given time period. For example, if there were a significant number of data points in the positive region from the period of 100 - 150 days with no corresponding data, points in the negative region, this would indicate a time dependency with respect to the drift. Since this, nor any other similar correlation is evident, it is concluded there is no time dependency to the drift.

This is accomplished by finding the worst case value in either the positive or negative direction, subtracting the mean from that value, taking the absolute value of the results, and dividing the resulting value by the standard deviation. This gives a result of the number of standard deviations the value is away from the mean. If the value is determined to be greater than the "Critical Value", the data point may be considered an outlier and removed from the data if there is a basis for removal. If the data is removed, the T-Test is repeated with revised worst case value, mean, and standard deviation, until the worst case data point is either less than the Critical Value or has no basis for removal.
Max value from Table = 0.017806 Min value from Table = -0.026286 Critical value for T-Test with a sample size of 521 and a Upper 5% Significance 3.33 Standard Dev = 0.003998 Mean= -0.000094 T-Test for Max value 0.017806 T-Test for Min value -0.026286 T-Test = 4.4771 T-Test = 6.5507 Because th e T-Test for both the Max and Min values are higher than the 3.33 value, they could be considered outliers and excluded from the sample. Due to there being no basis for removal, they will not be excluded. No further tests for outliers are required.

C-ICE-058.01-008 4 Normalcy Test - P/I/F Using the Chi-squared test for normalcy results in: - 178.29 based on groupings of bins below.
As there are 8 bins, a normal distributed data set would be below 8. Since it is above 8, the data is determined to be NOT normally distributed. Graphing the data results in a display of data that has a high kurtosis (middle peak) and 13 data values outside of 3 standard deviations. To graphically display the data, a series is established starting at the Mean and moving away from the Mean by the Standard Deviation. The number of data sets in each series are determined to be able to plot a normalcy graph.
The following table displays the series boundaries and the number of data sets in each series and compares that to thenormal distribution value. Due to the high kurtosis and the 13 values that are more than 3 standard deviations away from the mean, the data will be considered to be NOT normally distributed and will be included as a bias in the calculation.

C-ICE-058.01.008I 4 Time Dependency Analysis - P/I/F Time dependency analysis is used to determine if there is a correlation between the period between calibrations and the resulting change in setpoint. Each data point has been calculated along with the associated time duration between calibrations. Each of the data points used have been included in the plot below. As can be seen from the plot, there are no discernable indications that the drift is in any one direction based on a given time period. For example, if there were a significant number of data points in the positive region from the period of 100 - 120 days with no corresponding data points in the negative region, this would indicate a time dependency with respect to the drift. Since this, nor any other similar correlation is evident, it is concluded there is no time dependency to the drift.

Referring to Figure 3, generation. Here again,it is important to remember the main difference between the two is that when bus that only one voltage may exist on a field bus in a powered, in the 12V, the voltage (+V and -V) feeding the given SPEC 200 Nest. Note that H2V's and 12V's may field circuit is 24 V dc as developed in the DC/DC never be combined in the same nest.

Also \ powered only), Resistor Ra limits the current, from the the pulses to the chopper are developed by different voltage limited field bus. that can flow in the field circuits in the two units. circuit. Isolation and Resistors Rb and Rc limit the energy that can reach the field circuits to intrinsically The transmitted current is converted in the chopper safe levels from the amplifier circuits. This protection circuits to a square wave signal which can be transformer included accidental fault voltages up to 250 volts coupled (providing isolation) to the rectifier circuit. The nominalh rectified signal is connected to the amplifier which pro-duces output signal Eo (0-10 V dc). All of the SPEC 200 Voltage- t- Current Converters have a nominal frequency response such that the output When the circuits are externally powered, the is down 3 dB at 10 Hz. This response may be altered principle of operation is similar. In this mode of by changing capacitor values on the printed circuit card.
