NRC REQUEST FOR ADDITIONAL INFORMATION (RAI) 1:
- 1. Definition of 'Trip Level Setting" in TS Table 3.2-G:
Clarify what the column tile, 'Trip Level Setting," in TS Table 3.2-G, "Instrumentation that initiate Recirculation Pump Trip and Alternate Rod Insertion," represents compared to the setpoint terms listed in Figure 1 of Regulatory Guide (RG) 1.105, "Setpoints for Safety-Related Instrumentation," Revision 3, dated December 3, 1999.
Response
The term 'Trip Level Setting" in TS Table 3.2-G represents the Allowable Value (AV).
The proposed value of <1210 psig is the Allowable Value, which is also the notify Shift Manager value. It is the limiting value that the instrument setpoint may have when tested periodically, beyond which appropriate action will be required (See Response to RAI 3).
The instrument setpoint is 1203.6 +/- 1.9 psig and represents the process value at which the switch is expected to change state. The difference between the two values represents the allowable value to trip setpoint margin. The difference between the two values represents errors associated with the as-found tolerance and drift.
NRC RAI 2
- 2. Setpoint Calculation Methodology:
Provide documentation of the methodology used for establishing the limiting trip setpoint or normal trip setpoint and limiting acceptable values for the as-found and as-left setpoints as measured during the periodic surveillance testing. Documentation should:
- Include calculations.
- Indicate Analytical Limits and/or other limiting design values.
- Indicate the source of the parameters (Tolerances) used in calculating these three setpoint values and how they comply with RG 1.105 to ensure the 95/95 confidence level is achieved and these setpoints are adequate for the surveillance test interval specified in the plant surveillance requirements.
- As applicable, provide reference(s) to NRC approved documents related to this setpoint calculation.
RESPONSE TO RAI 2 Calculations and Analytical Limits to this Enclosure provides the calculation for ATWS RPT trip level setting, which provides analytical limits and design limiting values.
Source Parameters (Tolerances) for Setpoint Values Entergy has applied the process delineated in RG 1.105 as a means to calculate the analytical limits and design limiting values.
ATWS RPT/ARI instrumentation is not LSSS instrumentation as defined by the NRC in the Standard Technical Specification, Rev. 3, page B3.3.4.2-1 and ATWS is not assumed in the safety analysis. ATWS instrumentation is not safety-related, it is classified as "Management-Q" in accordance with NRC guidance provided for the implementation of ATWS Rule, and for the purpose of setpoint calculation, it is treated in the same manner as safety-related instrumentation.
NRC Approved Documents Related to Setpoint Calculation NRC approved Pilgrim License Amendment 151, dated April 6, 1994 (TAC Nos.M83787, M87191, and M88390) for the 24-month fuel cycle operation. Pilgrim applied for the License Amendment 151 in accordance with the guidance of NRC Generic Letter 91-04, "Changes in Technical Specification Surveillance Intervals to accommodate a 24-month Fuel Cycle". As described in the application for the License Amendment 151, Pilgrim performed setpoint calculations and drift evaluations using the guidance provided in Regulatory Guide 1.105, Rev. 2, Regulatory Position C, which specified ISA-$67.04-1982, "Setpoints for Nuclear Safety-Related Instrumentation Used in Nuclear Power Plants" for ensuring that the instrument setpoints in safety-related systems are initially within and remain within the technical specification limits.
Pilgrim setpoint calculations and drift evaluations using the ISA-$67.04-1982 practice provides for a 95/95 tolerance limit as acceptable criteria for uncertainties and forms the licensing bases for the Pilgrim setpoint methodology.
The ATWS RPT/ARI setpoint calculation is documented in Pilgrim Calculation No. IN1i-110, (Attachment 1) and follows the ISA-$67.04-1982 practice.
NRC RAI 3
- 3. Test Procedures:
Describe the measures to be taken to ensure that the associated instrument channels are capable of performing specified functions in accordance with applicable design requirements and associated analysis, including:
" Information on the controls employed to ensure that the as left trip setting after completion of periodic surveillance is consistent with the setpoint methodology.
- Discussion on the plant corrective action process for restoring the channels to operable status.
RESPONSE TO RAI 3 The setpoint calculation is documented in Pilgrim Calculation No. IN1-110, Revision 1 dated January 11, 2011. Surveillance procedures are utilized to control the setpoints, record as-found values, record and control as-left values, and identify setpoint drift issues. Pilgrim staff follows procedure EN-DC-1 15, "Engineering Change" process to ensure that calculated setpoints are translated accurately from design documents and associated analysis into procedures. The station process includes the following elements.
- 1. Instrumentation and Control (I&C) Design personnel prepare the design documents including calculations to determine the setpoint that will ensure that the protective action occurs at the proper value.
- 2. The set point is implemented via an Engineering Change process, which complies with the applicable requirements of 10 CFR 50, Appendix A and B, and licensing basis requirements.
- 3. I&C Maintenance personnel translate the calculated calibration values into the calibration procedure, as part of the EC process. With respect to the ATWS/RPT Trip Setting Level value, Pilgrim has implemented a surveillance procedure, 8.M.1-29, "ATWS Trip Unit Calibration Test' (Attachment 2). The procedure reflects the Technical Specification Value included in TS Table 3.2.G/4.2.G, and includes the following:
- Acceptance Criteria, based on controlled engineering documents
- Corrective Action
- Acceptance Verification
- I&C Procedure Feedback Form
- 4. Procedure 8.M.1-29 requires that a condition report be written in accordance with Entergy procedure, EN-LI-102, "Corrective Action Process", if the technician finds an as-found value is outside the no adjust limits. The corrective action process includes operability review, reportability review, engineering evaluation, and corrective actions to restore the equipment to operable status. Condition reports are assigned to Engineers for evaluation of performance issues discovered during periodic surveillances including repetitive findings of excessive drift.
Pilgrim EN-LI-102, "Corrective Action Process" complies with the requirements of 10 CFR 50, Appendix B. The EN-LI-102 process addresses equipment and instrument operability, restoring operability, interim acceptance of degraded conditions, and compensatory measures.
Upon receipt of the approved SRV and SSV License Amendment, Pilgrim procedure 8.M.1-29 will be revised to include revised Technical Specification values and applicable attributes for the ATWS/RPT setpoint calculations and control program.

Entergy CALCULATION SHEET Calculation IN1-110, Revision 1 SHEET NO. 4 of 40 I. PURPOSE I BACKGROUND A. PURPOSE:
The purpose of this calculation is to determine the setpoint and allowable value (Tech Spec value) for Reactor High Pressure ATWS switches PIS263-123A, B, C, and D.
EC5000071989 is replacing the four Safety Relief Valves (SRVs) and two Spring Safety Valves (SSVs). The setpoints associated with the four SRVs, SV-203-3A, B, C, & D and two SSvs SV-203-4A and B will be increased by 40 psig. The increase in SRV setpoints results in increased maximum reactor vessel pressure during transients. AT'WS ARI and Recirculation Pump High Pressure Trip setpoint is increased by 40 psi, consistent with the increase in setpoints of the SRVs and SSVs, and will provide the same level of protection to avoid tripping both recirculation pumps during transients that include a successful reactor scram.
B. BACKGROUND The Reactor High Pressure ATWS switches PIS263-123A, B, C, & D initiate recirculation pump trip (RPT) and alternate rod insertion (ARI) when the Reactor pressure exceeds the switch setpoint. They provide a back-up method for controlling reactivity in the unlikely event that the Reactor fails to scram when required (FSAR Section 3.9.1).
1I. DESIGN INPUTS / ASSUMPTIONS
- See Detailed Calculation Section IVfor design inputs.
- This calculation is performed based on the methodology described in PNPS NEDWI No.
433, (Reference 4). The calculation has been prepared in accordance with U.S. Nuclear Regulatory Commission Regulatory Guide No. 1.105, (Reference 53) and Instrument Society of America Standard ISA-$67.04 Part I - 1982, (Reference 54).
" Pressure Transmitters PT263-122A, B, C, & D are calibrated using maximum no adjust limits of +/- 0.04mA (+/- 025% of span) over a range of 4 - 20 mA (Reference 15). All measuring and test equipment will be assumed to have a combined accuracy of +
0.25% or better (Reference 30).
" Master Trip Units are calibrated using maximum no adjust limits of +/- 0.02mA (+/- 0.13%
of span) over a range of 4-20 mA (Reference 9). All measuring and test equipment will be assumed to have a combined accuracy of +/- 0.13% or better (Reference 30).
- The As-Found Tolerance (AFT) and As-Left Tolerance (ALT) is the tolerance allowed in the accuracy between calibrations of a device. The as found tolerance establishes the limit of error the device can have and still be considered functional. It is the band that
Entergy CALCULATION SHEET Calculation IN1-110, Revision 1 SHEET NO. 5 of 40 the device must be calibrated to within and remain to avoid recalibration when periodically tested. It is typically a value that is based on the accuracy of the device. The No Adjust Limits are used to determine if the technicians need to adjust the instrument.
- Calibration of Pressure Transmitters will be assumed to be conducted at a nominal frequency of every 24 months or better. However, a frequency of 30 months is used herein to be consistent with the Tech Spec (Reference 27) definition of surveillance frequency (U), which allows a maximum extension of 25% of the specified surveillance interval.
- Calibration of master trip units will be assumed to be conducted at a frequency of 3 months or better. However, a frequency of 4 months is used herein to be consistent with the Tech Spec (Reference 27) definition of surveillance frequency (U), which allows a maximum extension of 25% of the specified surveillance interval.
- This calculation will convert error effects to PSIG for calculating total loop uncertainty (TLU).
- Reactor and Turbine building normal temperatures are taken from FSAR Tables 10.9.1
& 10.9.2 (Reference 8), because the FSAR is the most recent controlled document reference source found with this information. The temperatures are assumed to be correct because they are the same as the temperatures identified in the Bechtel Design Basis Report 6498-HDBR-05 (Reference 41).
- The readability value used for channel crosscheck of the GE master trip unit is assumed based on the readability of the Rosemount master trip unit it replaced. This assumption is justified because the replacement was made for ATWS diversity reasons and the existing loop calibration range has been maintained.
- The determination for dynamic effects such as response time limits is addressed in the accident analysis and is not included within the scope of this calculation.

IV. DETAILED CALCULATION A. METHODOLOGY This calculation is performed per PNPS NEDWI No. 394, (Reference 4), and NRC GL 91-04 (Reference 29). The format of this calculation has been specifically modified to meet the content requirements identified in PNPS NED Procedure 3.05 (Reference 24).
PNPS setpoint calculations and drift evaluations are performed using ISA-$67.04-1982 practice and utilize 95/95 tolerance limits as acceptable criteria for uncertainties, as discussed in the application for License Amendment 151. This methodology using ISA-
$67.04-1982 and RG 1.105, revision 2 was the basis for License Amendment 151, and forms the licensing basis for Pilgrim setpoint methodology. The NRC approved Pilgrim License Amendment 151, dated April 6, 1994 (TAC numbers M83787, M87191, and M88390 for the 24 month fuel cycle operation. Pilgrim applied for License Amendment 151 in accordance with the guidance of NRC Generic Letter 91-04. "Changes in Technical Specification Surveillance Intervals to Accommodate a 24 month Fuel Cycle".
Af Entergy CALCULATION SHEET Calculation IN1-110, Revision 1 SHEET NO. 10 of 40 As described in the application for License Amendment 151, Pilgrim performed setpoint calculations and drift evaluations using the guidance provided in Regulatory Guide 1.105, Revision 2.
This calculation utilizes <-1220 psig for high pressure ATWS upper analytical limit provided by GE in NEDC-33532P. The goal of this calculation is to maintain the existing high pressure ATWS setpoint, while accounting for loop measurement uncertainty.
The manufacturer's drift specification is used for transmitters PT263-122A, B, C, D and master trip units PIS263-123A, B, C, D because there are not enough data points for a valid statistical analysis at this time.
This calculation covers four redundant loops. Where individual loop values differ, the values are compared and the worst case value is used for conservatism. If a loop is required to function during one or more accident scenarios, then the uncertainty effects due to each accident are calculated and compared and the single worst accident scenario is used in calculating total loop uncertainty. The individual switch safety function determines if the loop must function during an accident scenario. This loop is not required to function during an accident scenario. Note 17 provides a tabulation of the error terms for normal operation.
Pma is calculated for normal operation. This equipment is not required to function during accident scenarios (Reference 45). The normal operation Pma is due to temperature variations inside the drywell and Reactor building which affect the density of the reference leg column of water as well as static offset due to the difference between the actual condensate pot elevation and that used in scaling calculation IN 1-28 (Reference 38). Maximum and minimum Reactor building temperatures during normal operation were obtained from Reference 8. Maximum and minimum Drywell temperatures (Reference 52).
All errors identified in this calculation are individually evaluated to determine whether they are random or biases. In the context of instrument uncertainty, it is accepted within the industry that random uncertainties are those uncertainties that a manufacturer specifies as having a +/- magnitude. Random uncertainties are combined using the root sum of the squares (RSS) technique in accordance with NEDWI 394. Biases are expressed with either a + or - sign and are added together separately according to sign.
Individual component error terms which contain both a bias and a random value (for example, -0.95 +/- 0.5 psig) may be split up so that the random part (+/-0.5) is combined with other component error terms by the RSS method and the biases (-0.95) added to other component bias terms of the same sign. Both random and bias terms are added together to determine Total Loop Uncertainty (TLU). A random or bias term can also be further classified as being dependent or independent. Two error terms are classified as dependent if they posses a significant correlation, for whatever cause, known or unknown. Instrument proximity or physical connections alone do not cause dependency,

- 1. This equipment is not listed on the PNPS EQML and does not perform a safety function (See 10CFR50.62 - Reference 44). It initiates recirculation pump trip (RPT) and alternate rod insertion (ARI), which is a back-up method of reactivity control at reactor high pressure. This equipment is only required to function during anticipated operational occurrences. At PNPS this equipment is classified MQCI.
- 2. A value of 1045 psig will be used for the normal operation upper limit (NUL).
- 3. The ATWS recirculation pump trip setpoint is selected to trip the pumps during the initial reactor pressure transient following a failure of the control rods to insert. The selected trip set point is low enough to ensure that the ASME pressure limit for emergency events of 1500 psig is not exceeded. Note 2 to Table 3-3 "Key Equipment Parameters" in NEDC-33532P describes that the ATWS transient analysis uses a trip setpoint of 1220 psig, which is the analytical limit shown on Figure 2. The results of the worst case ATWS pressurization events are tabulated in Table 3-4 "Summary of Key ODYN Parameters for ATWS Calculation" and the worst case peak vessel pressure is 1478 psig. The analysis of 1220 psig is demonstrated to be adequate because the peak vessel pressure results from the transient analysis described in Section 3 of NEDC-33532P is below 1500 psig.
0 An analysis reactor steam dome pressure setpoint of 1220 psig is used for the ATWS Recirculation Pump Trip (RPT) function. Starting with Reload 18 Cycle 19 this analysis setpoint is specified for transient analysis that assumes a successful reactor scram performed for Reload Licensing Analysis (RLA) [Reference 50] and ATWS analysis
[Reference 46]. The previous analysis setpoint was 1180 psig which corresponded with the Technical Specification allowable value upper limit. The value of 1220 psig is referred to as the "Trip Level Setting" in Tech Spec 3.2.G.
- A lower analysis setpoint limit is not specified for the ATWS Recirculation Pump Trip (RPT) function:
0 Inadvertent trip of the recirculation pumps during a transient event that includes a successful scram is an operational inconvenience not a safety concern. The operational inconvenience arises due to the loss of forced circulation to sweep cold water from the reactor vessel bottom head. Reactor water level is manually raised to improve core flow by natural circulation and control thermal stratification in the bottom head.
0 The loss of both recirculation pumps is an evaluated transient that is non-limiting with respect to fuel thermal limits. As indicated by GEH in the OPL-3 Design Guide for RLA transient analysis inputs, increases in the RPT setpoint have minimal effect on peak pressure and causes negligible change in critical power ratio [Reference51].
- 4. In accordance with PNPS Procedure 1.3.36, measurement and test equipment utilized for calibration shall be equal to or better than the device being calibrated. The
Date 5/14/02 CALCULATION SHEET Entergy Calculation No. IN1-110 Revision 1 SHEET NO. 27 of 40 manufacturer's stated accuracy is +/- 0.25% span (Reference 1) for the transmitter and +
0.13% span for the master trip unit (Att. 1 & 3).
- 5. This calculation supports a 24 month fuel cycle.
- 6. The no adjust limits and reset will be based on the existing settings utilized. These values are shown in PNPS Procedures 8.M.1-30 and 8.M.1-29.
- 7. Evaluation of Reference Leg Temperature Variations on Reactor Vessel Pressure Measurement.
The distance from the bottom of the Reactor vessel to the bottom of the inside of the pipe from the Reactor vessel to the condensing pot for each train is calculated below.

From Reference 38 & 40, the reference leg penetration of the Drywell is at 534.375" for Train A and 535.75" for Train B. As depicted on drawing MIP-612 (Reference 5) and PNPS calculation INI-028 (Reference 38), the pressure transmitters are at 176.79" above reactor vessel zero (52.67' - 37' 11.25").

Pma = (13.36 - 13.4) / 1200*100% = -0.003% Span and can he neglected.
- 8. Rack Power Supply Effects (Rps):
Attachments 1 & 2 specify the performance parameters applicable to the GE master trip units.
Among these parameters are the supply voltage requirements for power to the units. It is assumed that if the input voltage is maintained within the design requirements of the trip units there will be no adverse affect on the performance specifications.
The master trip unit requires a supply voltage of 21.2 to 29.1 Vdc as described in Attachment
- 1. The ATWS power supplies are fed from two sources; 115 Vac distribution panels Y3 & Y4 and 125 Vdc distribution panels D36 & D37 (Reference 14). The outputs from D36 and D37 are converted to AC by voltage inverters prior to feeding the ATWS power supplies.The voltages throughout the ATWS trip circuits will remain within the equipment specifications and therefore no adverse performance from any ATWS equipment can be attributed to abnormal variations in supply voltages.

- 9. Rack Temperature Effects (Rte):
The temperature effect for the GE master trip unit trip output which provides the reactor high pressure ARI/RPT is listed in the GE proposal dated 9/30/91 (Attachment 3). This error is +/-
0.2% of full scale assuming the error is random for an internal cabinet temperature change from 113.5 0 F to 142.5°F. The corresponding external cabinet temperature is 76 0 F to 105 0 F.
PNPS FSAR Tables 10.9.1 & 10.9.2 list the minimum and maximum temperatures at the cabinet location (Reactor Building - 51 foot elevation) as 60OF to 105'F. Therefore; Rte = (+/-0.2%) (1500 psig) [(105'F - 60°F)/(105°F - 76°F] = _ 4.66 psig
- 10. Sensor Temperature Effect (St):
PT263-122A, B, C, & D are located on instrument racks C2275 & C2276, Rx bldg elevation 51' (Reference drawings M253 & M187).
Area temperature range: 60°F to 105'F (winter & summer design temperatures from FSAR tables 10.9.1 & 10.92)
Using V-0098 and proportioning the Ste at the pressure transmitter upper & lower range limits (URL & LRL):
SteURL = +/- 1% span per 100'F = +/- (0.01) (3000 psig) / 100°F = + 30.0 psig / 100°F SteLRL = + 3.5% span per 100'F = +/- (0.035) (500 psig) / 100°F + 17.5 psig / 100°F.
Therefore at the calibrated span of 1500 psig: (1500 - 500) psig / (3000 -500) psig = 0.4 psig Ste = +/- [(0.4) (30.0 - 17.5) psig/100°F] + +/- 17.5 psig / 100°F = +/- 22.5 psig/100°F Adjusting for temp. range: (+/- 22.5 psig/100°F) (105'F - 60'F) = +/-10.13 psig
- 11. Sensor Power Supply Effects (Spse):
Note 8 details the review of the voltage regulation for the ATWS trip circuits. The review confirms the GE master trip units have a supply voltage within required limits. These trip units provide supply voltage to the Rosemount transmitters, PT263-122A, B, C, and D. From Reference 1, Spse = (+/-0.005%) (1500 psig) (28v - 23v) = +/- 0.375 psig
- 12. Sensor Drift (Sd)
Reference 1 gives stability (drift) for model 1151G transmitters as +/-0.25% of URL for six months. Per Attachment 6, there will be no additional drift for at least two years after the first
Date 5/14/02 CALCULATION SHEET Entergy Calculation No. IN1-110 Revision 1 SHEET NO. 31 of 40 two days of operation/setting. Therefore, the value given in Reference 1 will be used to calculate Sd over the full calibration cycle:
Sd = +/-0.25% of URL = (+/-0.0025) (3000 psig) = +/- 7.5 psig
- 13. For actual values implemented at PNPS, see Figure 1.
- 14. A review of Reference 15 shows that the inaccuracy due to static pressure in the reference leg (from Reference 38) is accounted for in the calibration of the transmitters except for one minor calibration error. This term, CR, is the difference between the desired setpoint and the actual setpoint at which the trip will occur. This actual setpoint is determined by substituting the calibrated high setpoint in the transmitter calibration formula. The calibrated setpoint is 16.84 mA per Note 15 of this calculation. Convert this to the actual pressure the transmitter senses at the trip as follows; The ratio of mA to psig is obtained from Reference 15:
[(Actual Tsp + static Head)- 15) psig / (16.84 - 4.02) mA] = [(1510 - 15) psig / (19.97 - 4.02) mA]
Therefore, Actual Tsp = 1216.62 psig, which is 1203.22 psig + 13.4 psig static head (from Reference 38).
CR = Tsp - Actual Tsp = 1203.57 psig - 1203.22 psig = 0.35 psig This is a conservative error, i.e. the switch will trip before Reactor pressure reaches 1203.57 psig. Therefore this will not be included in TLU.
- 15. Calculated Reset Value & Trip Setpoint (Tsp):
Trip Setpoint:
Calibrated range: 0 to 1500 psig. span = 1500 psig Signal range: 4 mA to 20 mA, span = 16mA Tsp= 1203.57 psig Then:
Tss = [(1203.57 psig/1500 psig) (16 mA)] + 4 mA = 16.84 mA With no adjust limits (+/-0.02 mA): 16.82 mA to 16.86 mA (per Reference 9)
Reset Value:
Per Reference 21 & 36 the reset differential will be set at 0.32mA +/- .016mA (0.32mA/16mA) = 2% of span = (0.02) 1500 psig = 30 psig Therefore Reset Value = Tsp - 30 psig = 1203.57 psig - 30 psig = 1173.57 psig
Date 5/14/02 CALCULATION SHEET Entergy Calculation No. IN1-110 Revision 1 SHEET NO. 32 of 40 Convert to signal units:
16mA (1173.57 psig/1 500 psig) + 4mA = 16.52 mA which corresponds to a no adjust limit of +/-0.16mA (16.36mA to 16.68mA):
This reset value (RV) is acceptable because (1) reset occurs at 2% span, which falls within the manufacturer's specification of 0.5% to 20% of the input span and (2) reset occurs before the process normal operation limit is reached. See Figure 1.
- 16. Channel Cross Check Channel cross check criteria is intended to be used by PNPS operators to determine when a channel may be malfunctioning based on a comparison of its indicated value for a plant parameter versus the value displayed by the other channels displaying the same parameter. It is intended that this comparison will be performed during plant normal operation.
- 1. Methodology A. Total Loop Uncertainty for Cross Check The TLU used for cross check purposes is defined as:
2 2 2 2 2 TLUCROSSCHECK = j(PA)2 + (CA) +(RA) + (SA) + (DA) +(TA) where:
PA = Pea 2 2 CA2 = Sca + Rca Note: Rca includes the readability of the meter (1/2 minimum gradation)
RA 2= Rea 2 + Rte [N.O.] 2 + Ma2 Note: Rte [N.O.] is the error due to temperature difference between calibration and Normal Operation temperature. Ma is the master trip unit analog meter accuracy.
2 SA2 = Sa 2 + (Ssps + Sspz) + Ste[N.O.] 2 Note: Ste[N.O.] is the error due to temperature difference between calibration and Normal Operation temperature.
DA 2 = Sd2 + Red2
Date 5/14/02 CALCULATION SHEET Entergy Calculation No. INI-110 Revision 1 SHEET NO. 33 of 40 2 2 TA 2 =St + Ret Note: Ret is the "As Leff' setting tolerance of the meter indication.
The following terms from the equation for TLU in NEDWI 394 are not considered for the following reasons:
EA and its constituent terms Te, Re, S/Ce, Pe, and Se are not considered since these errors are associated with Post Accident conditions and the cross check is performed only during Normal Operation. Similar reasoning is why LA and its constituents Cl, TI, PI, SI, and DI are not considered.
The process measurement accuracy, Pma constituent of PA is not considered since it would equally affect all channels.
The sensor and rack power supply affects Spse and Rps, and are not considered because minor voltage variations on the 120 Vac buses are well within the regulation capability of the individual sensor and rack power supplies. Also, a severe degraded voltage condition is not considered, because this is not a normal plant operating condition.
For differential pressure transmitters in pressurized applications, the static pressure span and zero error terms, Ssps and Sspz, consist only of the random portion of the error. They account for the uncertainty in the correction actually applied and are still applicable.
B. Development of Channel Cross Check Criteria The purpose of this section is to discuss the derivation of the channel cross check methodology to be used at the Pilgrim Nuclear Power Station (PNPS). The purpose of the cross check process is to detect when a channel's performance begins to deviate from within analyzed bounds and is performed by comparing an individual channel's indication against some criteria.
An ideal test would be to compare the channel indication against the actual value of the parameter being monitored. In this case the criteria would be that "the difference between the indicated and the actual value must be less than the uncertainty established for the channel indication".
However, the actual value of a parameter is never known with absolute certainty. From a statistical standpoint, reduced uncertainty in the value of a parameter can be achieved by making a series of repeated independent measurements.
From Section 2, "Fundamental Considerations", of ASME PTC 19.1 - 1985 (Reference 64),
"Part 1 Measurement Uncertainty", if a series of independent measurements (readings) are made, then the mean value of the series is given by
Date 5/14102 CALCULATION SHEET AC O Entergy Calculation No. IN1-110 Revision 1 SHEET NO. 34 of 40 (i= (Xi)! N)
From the same document, the uncertainty associated with the mean value of a series of independent readings is related to the uncertainty in each of the measurements in the series used to calculate the mean value. This uncertainty is given by SS se ries S Mepan -- _____N Where Seriep - N and si = uncertainty associated with the ith measurement.
If the measurement uncertainties are the same (all Si = Smeasurement) then Sseries - SMeasurement and Swean=Sseries = S mcas..ement This indicates that if you are estimating the actual value of a parameter by averaging several measurements, then the uncertainty in your estimate decreases as the number of measurements in the average increases.
If one were to compare the indication of a single channel with the mean indication of several channels monitoring the same parameter, what would be an appropriate comparison criteria?
The criteria proposed is that "the difference between the indication of a single channel and the mean indication of several channels monitoring the same parameter must be less than the uncertainty established for the channel indication plus the uncertainty established for the mean value". Mathematically, the criteria is expressed as follows:
Re adhig ...... - t Re a .. nels Ch.,, Channel + SAean Reaic ...... -,
-(__N ReadingChanli~, NTha..... ,i ......., + S Channell*Nchmk Re t - .d"6ane < S hne ,, , t
Date 5/14/02 CALCULATION SHEET t 0AL Entergy Calculation No. INI-110 Revision 1 SHEET NO. 35 of 40 The criteria is based on the fact that the first uncertainty is that of the reading being compared and the second uncertainty is that of the standard being compared against. In the limiting case of N = 1, i.e. comparing two readings to each other, the criteria states that the difference must be less than twice the established channel indication uncertainty. In the limiting case of N approaching infinity the uncertainty associated with the mean value approaches zero and the criteria reverts to the ideal case above.
Using the above equation and substituting TLU Cross Check for SChannel and simplifying yields:

(No. of channels) TLU Cross check Multiplier (M) 2 1.707 3 1.577 4 1.500 7 1.378 8 1.354 The current PNPS Channel Cross Check procedure is performed by comparing two readings to each other, which is the limiting case of N=1 described above. Therefore, the calculation presented in Part 2 will consider both the Cross Check between Channels (limiting case of N=1) and the Cross Check against the average.
C. Application of Cross Check Criteria Round off the calculated cross check value to the nearest readable value. Compare the calculated value of the cross check criteria to the existing value taken from PNPS Procedures.
Ifthe existing value is larger than the calculated value, coordinate with PNPS ICED to evaluate reducing the existing cross check criteria to the calculated value. If not, use the existing value.

Seismic Qualification Profile The Required Response Spectrum is provided in Attachments 12 and t3. These spectra represent the minimum floor acceleration spectra to be applied to the MTU and STU (Slave Trip Unit) enclosure (cabinets only). The seismic exposure levels for both Operating Basis XEarthquake (OBE) and Safe Shutdown Earthquake (SSE) for a cabinet containing the trip units are also contained in Attachments #2 and 13. The figures do not include amplification from the floor to the trip unit mounting locations.
The seismic exposure levels to which the trip units may be exposed during plant life are dependent on the seismic levels at their mounting locations. Attachments 14 thru 19 show the trip unit seismic qualification levels. These figures do not include any margin.
The trip units required seismic testing using multifrequency test inputs. The Test Response Spectra (TRS) at the cabinet assembly base were to exceed the service conditions of Attachments 12 and
- 13. This assured that the trip units in their mounting locations experienced actual seismic levels in excess of their specified service condition. The trip units were to be subjected to five OBEs and one SSE in two orientations. The Required Response Spectra (RRS), Attachment i10 and #11, used during seismic testing as input into the cabinet containing installed aged trip units exceeded the service conditions of Attachments 12 and 13 by at least 21%.

A-TT. INI-110 GE-lfE-901-ool- 0491 I. BACKGROUND ON MASTER TRIP UNIT- (MTU) AND SLAVE TRIP UNIT (STU)
The base number for the GE Trip Unit is 184C5988GXXX, where the three X's will be replaced with a three digit number, such as 184C5988GI12.
Master Trip Units belong tot.the Group 100, 200, 400, 500, or 600. Trip Units series. Slave Trip Units are the Group 300 and 700 series.
TRIP UNIT GROUPS APPLICATION INPUT RESET GROUP FILTER DIFFERENTIAL (Hz)()

When- the input signal reaches a predetermined value (the setpoint), the HTU changes the state of its trip output. The MTU visually indicates the magnitude of the process parameter monitored with a meter on its front panel. The HTU provide 1 to 5 Vdc output signals, linearly related to the input signal. One output is for driving Slave Trip Units (STU), the other for driving auxiliary analog devices (recorders, meters, etc.).
It should be noted that the GE Trip Units are a direct "plug-in" compatible unit with the Rosemount unit, and no additional accessory hardware and/or components such as card files, calibration units, readout assemblies, card extenders, etc.
are required.

GE-W7-Qn1_001_0491 A-i-r. !II. F.ASTER TRIP UNIT CALIBRATION AND GROSS FAILURZ SETPOINTS Each MTU provides gross failure detection circuitry which detects when the input signal has deviated beyond the normal 4-20 ma process range. The MTU provides high. and low, adjustable gross failure limits. The gross failure output will be low and the gross failure indicator off until the input signal exceeds either gross failure limit; then, the gross failure output will latch high and the gross failure indicator will illuminate and latch.
The High Gross Failure Setpoint is adjustable from approxi-mately 20 to 40 milliamps. The Low Gross Failure Setpoint is adjustable from approximately 0.4 to 4.0 ma. A momentary contact pushbutton resets the gross failure indicator when illuminated and latched, if the input signal has returned to its normal range. The momentary contact pushbutton also resets the gross failure -output when latched, only if the input signal has returned to its normal range, and the trip unit is not in the calibration mode.
When the input signal is disconnected from the MTU, and the
-TU is not in the calibration mode, the gros's failure output latches high, and the gross failure indicator illuminbtes.
Terminals 8 and 9 are shorted together on the printed circuit (PC) card. This feature is used as part of a continuity loop to detect a "card-out-of-file" condition.
The front-mounted TRIP status indicator, which illuminates when the input -signal reaches (or exceeds) the setpoint, is labeled TRIP. The front-mounted GROSS, FAILURE status indicator which illuminates when either gross failure limit is exceeded is labeled GROSS FAILURE.
The GE units are plug-in compatible replacements with the Rosemount units and basically utilize similar calibration requirements. There are slight differences in the Gross Fail and Trip Setpoint Hysteresis setpoints. It should be noted that even though the differences are slight, it may require a "note" correction to the. Surveillance & 'Operational Test Procedures or Calibration Procedures to account for slight differences in the reset points.

-IV. MAXIMUM ALLOWABLE TRANSMIaTTER LOOP RESISTANCE Total transmitter loop resistance between the +25 Vdc (nominal) power supply and signal common (excluding the resistance of the transmitter and the wiring to and from the MTU to the transmitter) is to be less than 330 ohms.
The loop is powered by -"the MTU from an external +25 Vdc (nominal) power supply which is connected as input power to the MTU.
V. PERFORMANCE SPECIFICATIONS FOR 18-MONTH. DRIFT AND THE EFFECTS OF TM-PERATURE, SEISMIC VIBRATION, AND RADIATION ON THE ACCURACY OF TEE TRIP UNIT Performance specifications for 18-month drift for the YTU would be strictly from empirical data, and does not exist at this time.
Drift is expressed in Percent Full Scale (%FS) of calibrated span for a one month interval.
The MTU meets or exceeds the design drift values* listed as follows:
Normal: 0.10% FS
. Abnormal (1 Day/Year): 0.20% FS Design Basis Earthquake (DBE)
(LOCA-HELB 180 Days): 0.10%FS where LOCA = Loss of Coolant Accident HELB = High Energy Line Break The desicn drift value is defined as the amount the output, test jack value, or setpoint deviates from the value it was set at during calibration and the value at which it is found or trips at the end of one month under the identical operational and environmental conditions of the preceeding calibration.

VI. SEISMIC QUALIFICATION OF THE GE TRIP UNIT AND ROSEHOUNT CARD FILE CONTAINING GE TRIP UNITS OR BOTH GE AND ROSEMOUNT TRIP UNITS The GE Analog Trip Units have been seismically a'.ialified zo generic, bounding seismic exposure levels. Durinc qualification tests, the Test Response Spectra exceeded the Required Response Spectra. This assured the Trip Units at their mounting locations in the test cabinet experienced seismic levels in excess of their specified service condition.
The Trip Units were operational during OBE and SSE tests.
They were subjected to at least five OBEs and on SSEs in two orientations.
Seismic qualification and adequacy evaluations of specific mounting and service conditions can be performed by analysis and upon request.

A-1-n IN1-1 I 10 Attachment To HAD 91- e=R go 627--ln76 Background/Purpose-he current technical specifications for POPS specify high reactor pressu d low reactor water level setpoints for ATHS mitigation at allowable v ues e 1 to that used In the analyses of record, NEDO-25016. Analytical lues in later document, NEDC 31425. have additional margin for measur unce inty. However, this document was not reviewed and accepted BECo until cently. I&CS #91-314 requests that NAD resolve the differ ces between e documents and related issues. This nedorandum respo s to the same.
Discussion NEDC 31425 was viewed and accepted by SUDDS91-178. Th upper analytical limit for high p sure ATHS is 1220 psia (1205 psig). rrently, the lower analytical limit i 1190 psia (1175 psig). This limit s not ATWS related and has only a slight a ct on reload analyses' peak pre ures. Based on the typical sensitivity g en in GE document A63HA247. ., Sheet 30 and the margin available in the nalysis of Cycle 9, an an ytic limit of 1145 would not invalidate the curre core analysis. A valu of 1145 psig will be used in the cycle 10 reload ana sis. The analytical imit for reactor water level is -57 inches based upon a c rificatlon to HE 31425, Table A-2, as given in GE-NE-187-69-1291 (p. 4-6, 7). See also SUOD 91-177.
There are no errors associated wi these tpoints except that identified in GE letter LLC-52-91. ATHS must be uncti nal for the pressure range from 800 psig to 1205 psig. ATHS events a depressurize the reactor would be isolated at 800 psig and repressurize e to reactor power. ATHS need not be functiocal above the pressure it is s ned to actuate. The reactor water temperature range is 500OF-5706F. e a temperature in the drywell is not expected to vary significantly fr normal uring an ATHS. However, we recommend assuming a range of 10 150°F. T analytical limits are not a function of operating pressure nd temperatur NAD will provide a resoluti to S&SA memo 91-67.
Conclusion The above information rovides a response to I&S #191- 4.

[2] The ATWS System provides for an addition of negative reactivity to the core (tripping Recirculation Pumps and letting air off Scram header) in the event of a transient (Hi-Hi Reactor pressure or Low-Low Reactor water level) without a Scram having taken place.
[3] The ATWS System is composed of four trip channels which make two trip systems.
Channels "A" and "C" compose Trip System "A" and it is housed in Panel C2277.
Channels "B" and "D" compose Trip System "B" and it is housed in Panel C2278.
NOTE Recirculation pump trip circuits are valid only when pumps are running. Lights will be off when pumps are off.
Feedwater pump trip circuits are valid only when pumps are running. Lights will not light when the pumps are off.
Neon lamps are used in these circuits to minimize the current flow through the trip coil and prevent false trip.
[4] Each trip system has three trip circuits, each trip circuit is equipped with a light system.
Two neon lamps are connected in series and are in series with a trip coil. During normal operation the trip relays are de-energized (untripped) and normal voltage across each neon lamp is approximately 66V DC.
[5] When one trip relay energizes (half-trip), the voltage across lamps connected in parallel with.closed contacts will go to approximately 0 volts DC and the lamps will turn off. This indicates tripped relay contacts have closed. Relay contacts and associated lamps are listed in Attachments 1 and 2.
[6] The indicator lights used are neon lamps which, when lit with one channel tripped, draw insufficient current to actuate the trip devices. When no channel is tripped, it is intended that none of the indicator lights be lit. However, because the voltage to maintain neon lamps lit is less than the threshold firing voltage of lamps, in some cases, both lamps in series may be lit. Therefore, when no channel is tripped, the pairs of indicator lamps may be either both lit or both off. When a channel is tripped, only one of the lights will be lit.
[7] Notify Operations that EPIC "RPV Level Validation Screen #71" will be affected during the calibration of LIS-263-121A and LIS-263-121C.

5.0 SPECIAL TOOLS AND EQUIPMENT
[1] Rosemount readout assembly and extender card
[2] Multimeter
[3] CR keys for access to Racks C2277 and C2278 6.0 PRECAUTIONS AND LIMITATIONS 6.1 PRECAUTIONS
[1] Only one master trip unit and associated slave unit(s) may be tested or calibrated at a given time.
[2] Exercise caution while performing test. Reactor Scram and inadvertent safeguard initiation could be the result of not following instructions.
[3] During the prejob brief the need for extra caution when manipulating the trip unit Calibration Selector knob (Press To Cal small knob) needs to be discussed. It is necessary to verify that the calibration unit CAL light does not light while manipulating the rotary knob. Whenever the CAL light is on, the calibration current is being supplied to the selected trip units. If care is not taken when using the trip unit Calibration Selector knob (Press To Cal small knob), the potential exists that an ATWS may be received if multiple trips occur. (PRO1.8151)
[4] The indicator lights used are neon lamps which, when lit with one channel tripped, draw insufficient current to actuate the trip devices. When no channel is tripped, it is intended that none of the indicator lights be lit. However, because the voltage to maintain neon lamps lit is less than the threshold firing voltage of lamps, in some cases, both lamps in series may be lit. Therefore, when no channel is tripped, the pairs of indicator lamps may be either both lit or both off. When a channel is tripped, only one of the lights will be lit.
[5] I&C Technicians shall use a different Rosemount readout assembly for Attachment 2 than what was used in Attachment 1.
6.2 LIMITATIONS The ATWS System is only required when the REACTOR MODE switch is in the RUN mode.
Refer to Technical Specifications Table 3.2.G for the required number of instrument channels per trip system.

[2] ATWS System must be powered up.
[3] Readout assembly must be calibrated in accordance with PNPS 3.M.1-10.4, "Calibrationof Rosemount Trip Unit Readout Assembly', prior to use. After calibration, readout assembly shall not be left unattended until its usage for this Procedure is finished.
[4] Check with Radiation Protection (RP) on conditions and requirements. Initiate a Radiological Work Permit (RWP) if required.
[5] Obtain the on-shift SRO's signature for permission to begin test.
8.0 PROCEDURE
[1] One or more trip units may be skipped while performing this Procedure. After performing calibration of number of trip units desired, Return to Service steps must be performed. Upon completion of trip unit calibration, alarm(s) associated with the trip unit must be reset before proceeding to next trip unit.
[2] WHEN test is being performed with Reactor Recirculation Pumps and Reactor Feed Pumps not running, ENTER "NIP" (for "not performed") for steps which verify circuit supervisory lights become bright. (Lights are normally off when pumps are not running.)
(a) ARI circuit supervisory lights DS5A, B, C, and D are valid during all plant conditions and must operate according to Procedure.
[3] WHEN test is being performed with Reactor Recirculation Pump and Reactor Feed Pumps running, ENTER "NIP" (for "not performed") for steps which verify relay status.
(Lights changing status verifies relay status change.)

2.0 SAFETY LIMITS (Cont)
REACTOR STEAM The Safety Limit for the reactor steam dome pressure has DOME PRESSURE been selected such that it is at a pressure below which it can (2.1.4) be shown that the integrity of the reactor coolant system is not endangered. The reactor pressure limit of 1340 psig as measured in the vessel steam dome was derived from the design pressure of the reactor vessel. The peak pressures for the piping systems connected to the reactor vessel have been recalculated based on a reactor steam dome peak pressure of 1340 psig. These peak pressures are below the lowest of the transient pressures permitted by the applicable design code: ASME Boiler and Pressure Vessel (B&PV) Code (1965 Edition, including the January 1966 Addendum) for the pressure vessel, USAS Piping Code B31.1 for the steam space piping and ASME Section III for the reactor coolant system recirculation piping. The ASME B&PV Code permits pressure transients up to 10% over the design pressure (110% x1250=1 375 psig). The USAS Piping Code and ASME Section III permit pressure transients and other occasional loads whose combined effect do not exceed stress levels based on the duration of the loads and the applicable service limit.

3.2 PROTECTIVE INSTRUMENTATION (Cont)
The recirculation pump trip/alternate rod insertion systems are consistent with the "Monticello RPT/ARI" design described in NEDO-25016 (Reference 1) as referenced by the NRC as an acceptable design (Reference 2) for RPT. Reference 1 provides both system descriptions and performance analyses. The pump trip is provided to minimize reactor pressure in the highly unlikely event of a plant transient coincident with the failure of all control rods to scram. The rapid flow reduction increases core voiding providing a negative reactivity feedback. High pressure sensors and low water level sensors initiate the trip. The recirculation pump trip is only required at high reactor power levels, where the safety/relief valves have insufficient capacity to relieve the steam which continues to be generated in this unlikely postulated event. Requiring the trip to be operable only when in the RUN mode is therefore conservative. The low water level trip function includes a time delay of nine (9) seconds +/- one (1) second to avoid increasing the consequences of a postulated LOCA. This delay has an insignificant effect on ATWS consequences. Additional analysis of the ARI/RPT Setpoint for High Reactor Dome Pressure is identified in Reference 3.
Alternate rod insertion utlizes the same initiation logic and functions as RPT and provides a diverse means of initiating a reactor scram. ARI uses sensors diverse from the reactor protection system to depressurize the scram pilot air header, which in turn causes all control rods to be inserted.

Drywell Temperature The drywell temperature limitations of Specification 3.2.H.1 ensure that safety related equipment will not be subjected to excess temperature. Exposure to excessive temperatures may degrade equipment and can cause loss of its operability.
The temperature elements for monitoring drywell temperature specified in Table 3.2.H were chosen on the basis of their reliability, location, and their redundancy (dual -
element RTD's). These temperature elements are the primary elements used for the PCILRT.
The "nominal instrument elevations" provided in Tables 3.2.H and 4.2.H assist personnel in locating the instruments for surveillance and maintenance purposes and define the approximate containment region to be monitored.

HPCI System B 314.5.E B 3/4.5 CORE AND CONTAINMENT COOLING SYSTEMS 3/4.5.E Automatic Depressurization (ADS) System BASES BACKGROUND This specification ensures the operability of the ADS under all conditions for which the automatic or manual depressurization of the nuclear system is an essential response to station abnormalities.
The nuclear system pressure relief system provides automatic nuclear system depressurization for small breaks in the nuclear system so that the low pressure coolant injection (LPCI) and the core spray systems can operate to protect the fuel barrier.
Because the Automatic Depressurization System does not provide makeup to the reactor primary vessel, no credit is taken for the steam cooling of the core caused by the system actuation to provide further conservatism to the CSCS. Performance analysis of the Automatic Depressurization System is considered only with respect to its depressurizing effect in conjunction with LPCI or Core Spray. There are four valves provided and each has a capacity of 921,235 lb/hr at a reactor pressure of 1155 psig. I APPLICABLE The limiting conditions for operating the ADS are derived from the SAFETY Station Nuclear Safety Operational Analysis (FSAR Appendix G) and a ANALYSIS detailed functional analysis of the ADS (FSAR Section 6).
ACTIONS The allowable out of service time for one ADS valve is determined as 14 days because of the redundancy and because of HPCI operability; therefore, redundant protection for the core with a small break in the nuclear system is still available.
SURVEILLANCES The testing interval for the core and containment cooling systems is based on industry practice, quantitative reliability analysis, judgment and practicality. The core cooling systems have not been designed to be fully testable during operation. For example, complete ADS testing during power operation causes an undesirable loss-of-coolant inventory. When components are tested and found inoperable the impact on system operability is determined, and corrective action or Limiting Conditions of Operation are initiated. A simulated automatic actuation test once each cycle combined with code inservice testing of the pumps and valves Is deemed to be adequate testing of these systems. The ADS test circuit permits continued surveillance on the operable relief valves to assure that they will be available if required.
The surveillance requirements provide adequate assurance that the core and containment cooling systems will be operable when required.

The 2 gpm limit for unidentified coolant leakage rate increase within any 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period is a limit specified by the NRC in Generic Letter 88-01: "NRC Position on IGSCC in BWR Austenitic Stainless Steel Piping". This limit applies only during the RUN mode to accommodate the expected coolant leakage increase during pressurization.
The total leakage rate consists of all leakage, which flows to the drywell equipment drain sump (Identified leakage) and floor drain sump (Unidentified leakage).
In addition to the sump monitoring of coolant leakage, airborne radioactivity levels of the drywell atmosphere is monitored by the Reactor Pressure Boundary Leak Detection System. This system consists of two panels capable of monitoring the primary containment atmosphere for particulate and gaseous radioactivity as a result of coolant leaks D. Safety and Relief Valves The valve sizing analysis considered four relief/safety valves and two safety valves. The set pressures are established in accordance with the following three requirements of Section III of the ASME Code:
- 1. The lowest safety valve must be set to open at or below vessel design pressure and the highest safety valve be set at or below 105% of design pressure.
- 2. The valves must limit the reactor vessel pressure to no more than 110% of design pressure. 1
- 3. Protection systems directly related to the valve sizing transient must not be credited with action (i.e., an indirect scram must be assumed).

D. Safety and Relief Valves (Cont)
A main steam line isolation with flux scram has been selected to be used as the safety valve sizing transient since this transient results in the highest peak vessel pressure of any transient when analyzed with an indirect scram. The original FSAR analysis concluded that the peak pressure transient with indirect scram would be caused by a loss of condenser vacuum (turbine trip with failure of the bypass valves to open). However, later observations have shown that the long lengths of steam lines to the turbine buffer the faster stop valve closure isolation and thereby reduce the peak pressure caused by this transient to a value below that produced by a main steam line isolation with flux scram.
Item 3 above indicates that no credit be taken for the primary scram signal generated by closure of the main steam isolation valves. Two other scram initiation signals would be generated, one due to high neutron flux and one due to high reactor pressure. Thus item 3 will be satisfied by assuming a scram due to high neutron flux.
Relieving capacity of 4 relief/safety valves in combination with 2 safety valves results in a peak pressure during the transient conditions used in the safety valve sizing analysis which is well below the pressure safety limit.
The relief/safety valve settings satisfy the Code requirements that the lowest safety valve set point be at or below the vessel design pressure range to prevent unnecessary cycling caused by minor transients. The results of postulated transients where inherent relief/safety valve actuation is required are identified or referenced in the Updated Final Safety Analysis Report.
Experience in safety valve operation shows that a testing of at least 50% of the safety valves per refueling outage is adequate to detect failures or deterioration. The tolerance value of t 3%
is in accordance with Section III of the ASME Boiler and Pressure Vessel Code. An analysis has been performed which shows that with all safety valves set 3% higher, the reactor coolant system pressure safety limit of 1375 psig is not exceeded.
The relief/safety valves have two functions; i.e., power relief or self-actuated by high pressure.
Power relief is a solenoid actuated function (Automatic Pressure Relief) in which external instrumentation signals of coincident high drywell pressure and low-low water level initiate the valves to open. This function is discussed in Specification 3.5.E. In addition, the valves can be operated manually.
