CALCULATION NUMBER: 9000041128 REVISION: 1 PAGE 10 OF 152 CALCULATION TITLE: 4.16 kV Bus FLUR & SLUR Setpoint Calculation DATE: 03/22/2011
- 1. Purpose This calculation establishes the basis for technical specifications and setpoints of the vital 4kV busses' First Level Undervoltage Relays and Second Level Undervoltage Relays (referred to as FLUR and SLUR respectively throughout this calculation). This calculation supports the resolution of notification 50301167 and the replacement of the Unit 1 and Unit 2 First Level and Second Level Undervoltage Relays (FLUR and SLUR). A licence amendment request will be submitted to the NRC requesting approval for replacing the FLUR's and SLUR's with models of greater accuracy and for re-designing the relay logic to address outstanding concerns over the adequacy of the equipment protection provided by the FLUR's and SLUR's.
The First Level Undervoltage Protection consists of the 27HxB2 (Transfer to startup & diesel start) relays, the 27HxT1 (Time Delay Load Shed) relay and the 27HxT2 (Instantaneous Load Shed permissive) relay. The subject modification will change the make and model for the FLUR Instantaneous Load Shed Relay (27HxT2) and the FLUR Time Delay Load Shed Relay (27HxT1). The FLUR Time Delay Load Shed Relay will now be made up of 3 independent relays for each bus (27HxT1A, 27HxT1B, 27HxT1 C). Each relay will initiate load shed timing at different levels of voltage degradation on the bus (LOW VOLTAGE, LOW-LOW VOLTAGE & LOSS OF VOLTAGE) respectively. The FLUR relay responsible for transfer to startup and diesel start (27HxB2) will not be modified, however its tech spec and setpoint basis are included as part of this calculation. For the 27H*B2 relays, the pickup setpoint is not adjustable and it is a function of dropout. This calculation also provides an analysis of relay performance of the 27H*B2 relays based on recent calibration data.
The Second Level Undervoltage (Voltage Sensing) Relays and their associated timers will also be replaced with more accurate models. The setpoints will be changed to enhance equipment protection and optimize availability of offsite power. The Tech Spec limits for the SLUR setpoints will not be changed.
Throughout this document, the under-voltage setpoint activated due to drop in the bus voltage is referred to as "dropout setpoint" and the reset activated due to rise in bus voltage is referred to as "pickup setpoint". This calculation also computes the burden on each potential transformer that reduces the 4kV bus voltage to -120VAC measurable signal.
The following devices are within the scope of this calculation:

- 2. Background Per FSAR Section 8.3.1.1.8.2, the DCPP emergency electrical power system including each vital bus and its control protection, and instrumentation was originally designed in accordance with IEEE Standards 308-1971 and 279-1971. These standards required loss of voltage detection and initiation of protection signals which were implemented via a first level of undervoltage protection. The original design function of this first level of undervoltage protection was detection and recovery of loss of voltage.
PG&E received additional requirements for a second level of undervoltage protection relays in a letter from the NRC dated November 22, 1977. These requirements were reflected in DCPP SSER 9. The following discussion defines each criteria and how it is satisfied by the FLUR/SLUR relays or a DCPP calculation or analysis.
(1) We require that a second level of voltage protection for the onsite power system be provided and that this second level of voltage protection shall satisfy the following requirements:
a) The selection of voltage and time set points shall be determined from an analysis of the voltage requirementsof the safety-related loads at all onsite steam distributionlevels;
- Voltage studies have been performed of vital 4kV motor starting and steady state loading to determine motor protective device trip times and adequacy in calculation 170-DC [ref. 12.1.58]. These trip times have been considered in establishing FLUR and SLUR load shed setpoints.
" Voltage studies have been performed of vital 480VAC loads for starting and steady state to determine motor protective device trip times and adequacy in calculation 9000041185 [ref. 12.1.59]. These trip times have been considered in establishing FLUR and SLUR load shed setpoings.
- Voltage studies have been performed of vital loads fed at each vital power distribution level by fuses in calculation 9000041186 [ref. 12.1.60]. Impacts of degraded voltage on vital loads fed by fuses have been considred in establishing FLUR and SLUR load shed setpoints.
b) The voltage protection shall include coincidence logic to preclude spurious trips of the offsite power source;
- The FLUR relays require a 2 out of 2 coincident logic in order to load shed the vital 4kV busses.
- The SLUR relays require a 2 out of 2 coincident logic in order to load shed the vital 4kV busses and start the emergency diesel generators.
c) The time delay selection shall be based on the following conditions:
(i) The allowable time delay, including margin, shall not exceed the maximum time delay that is assumed in the FSAR accidentanalyses; File Name: 9000041128 (357S) Rev 1.doc 6/22/2011
CALCULATION NUMBER: 9000041128 REVISION: 1 PAGE 12 OF 152 CALCULATION TITLE: 4.16 kV Bus FLUR & SLUR Setpoint Calculation DATE: 03/22/2011 Per Notification 50301167 Task 18 and Design Input Transmittal 50301167 0, Westinghouse has evaluated the impact of the maximum SLUR load shed time delay on the DCPP safety analyses. This calculation ensures that all relay actuations (including setpoint and uncertainty) occur within the 20 second SLUR load shed Tech Spec limit assumed in the safety analyses.
(ii) The time delay shall minimize the effect of short duration disturbancesfrom reducing the availabilityof the offsite power source(s);
- The adequacy of the SLUR and FLUR relay time delays and their impact on the availability of the offsite power source is evaluated in calculation 359-DC.
(iii) The allowable time duration of a degraded voltage condition at all distribution system levels shall not result in failure of safety systems or components;
- Calculation 170-DC [ref. 12.2.10] will take the voltage and time setpoints for the FLUR and SLUR relays and determine adequacy of motor protection for vital 4kV loads.
- Calculation 9000041185 [ref. 12.2.11] will take the voltage and time setpoints for the FLUR and SLUR relays and determine adequacy of load protection for vital 480VAC loads.
- Calculation 9000041186 [ref. 12.1.60] will take setpoints from this calculation and determine adequacy of load protection for loads fed by vital fuses.
(iv) The voltage sensors shall automatically initiate the disconnection of offsite power sources whenever the voltage set point and time delay limits have been exceeded; The following description of the FLUR and SLUR relay functions describe the automatic actions of these relays.
FLUR The first level under-voltage protection relays (FLUR) detect the degraded and the loss of voltage conditions on the vital 4.16Kv busses. The first level under-voltage protection relays are made up of 5 different relays each with its own voltage sensing setpoint and time delay.
The 27HxB2 relay is a microprocessor based relay with a three step voltage vs time profile. This relay is responsible for initiating the transfer to start up and diesel generator start signals when its voltage and time setpoints are met. After a sufficient time delay they allow the transfer of vital busses to the startup transformer. Diesel generators are automatically started on sustained bus under-voltage.
The 27HxTIA, B and C relays provide a three tier voltage vs. time profile for load shedding the vital 4kV bus. The 27HxT1A detects low vital bus voltage, the 27HxT1 B detects low-low vital bus voltage and the 27HxT1 C detects loss of vital File Name: 9000041128 (357S) Rev 1.doc 6/22/2011
CALCULATION NUMBER: 9000041128 REVISION: 1 PAGE 13 OF 152 CALCULATION TITLE: 4.16 kV Bus FLUR & SLUR Setpoint Calculation DATE: 03/22/2011 bus voltage. The time delay associated with each "TI" relay decreases with lower bus voltage setpoint.
The 27HxT2 relay is an instantaneous relay with one voltage setpoint. The function of the "T2" relay is to provide coincidence logic to preclude spurious trips of the offsite power sources. Actuation of either of the three "TI" relays and the "T2" relay will load shed the respective vital 4.16Kv bus. If the transfer to the Startup Transformer is unsuccessful, the FLURs will shed the vital bus motor loads. Diesel breaker closing is time delayed approximately 2 seconds to allow the motor breakers to trip and bus voltage to decay. After the diesel generator breaker closes, the vital bus will be loaded in a predetermined sequence.
SLUR The second level undervoltage relays (SLUR) detect bus voltage approaching the 3785V limit (approximately 90% of bus voltage) and provide diesel generator start and vital 4.16kV bus load shed signals. The 3785V setting is based on NRC second level undervoltage relay setting requirements [Ref. 12.1.12, page 43].
The second level under-voltage protection relays are made up of 4 different relays each with its own voltage sensing setpoint and time delay.
The 27HxB3 relay is a solid state near instantaneous relay with one voltage setpoint. Similarly the 27HxB4 relay is also a solid state near instantaneous relay with one voltage setpoint. Together these relays provide undervoltage protection and two out of two coincidence logic is required to preclude spurious trips of the offsite power sources. When the coincidence logic is made up, the undervoltage signal initiates two separate timing relays 62Hx3A and 62Hx3B.
The 62Hx3A relay initiates diesel start after a maximum time delay of 10 seconds.
This maximum time delay for diesel starts is accounted for in DCPP's accident analyses.
The 62Hx3B relay initiates vital 4.16kV bus load shed after a maximum time delay of 20 seconds. The maximum time delay of 20 seconds is based on allowed short time overheating of motors due to undervoltage. This time is based on motor manufacturer's maximum motor starting time of 20 seconds [Ref. 12.1.12].
(v) The voltage sensors shall be designed to satisfy the applicable requirementsof IEEE Std. 279-1971, "Criteriafor Protection Systems for Nuclear Power Generating Stations;"and Per FSAR Section 8.3.1.1.8.2, the DCPP emergency electrical power system including each vital bus and its control protection, and instrumentation was originally designed in accordance with IEEE Standards 308-1971 and 279-1971.

CALCULATION NUMBER: 9000041128 REVISION: 1 PAGE 14 OF 152 CALCULATION TITLE: 4.16 kV Bus FLUR & SLUR Setpoint Calculation DATE: 03/22/2011 (vi) The Technical Specification shall include limiting condition for operation, surveillance requirements, trip setpoints with minimum and maximum limits, and allowable values for the second-level voltage protection sensors and associatedtime delay devices.
DCPP TS 3.3.5.3 provides a minimum voltage value for the FLUR and SLUR TS limits. Calculation 357S-DC establishes the technical specification bases, TS minimum voltage and maximum time delay limits and allowable maximum and minimum as-found values for the FLUR/SLUR calibration acceptance criteria. NUREG-1431 provides a minimum and maximum voltage value for the FLUR and SLUR TS limits. DCPP technical specifications have never had maximum limits for the FLUR/SLUR voltage sensing trip setpoints. A maximum setpoint would be non-conservative in that it would reduce the margin available for offsite power availability. The configuration at DCPP was approved in SSER 9. Additionally, a review of industry technical specifications concluded that the following plants provide only a minimum voltage value for the FLUR and SLUR TS limits: Catawba Units 1 and 2, Braidwood Units 1 and 2, Beaver Valley Units 1 and 2, Millstone Unit 3, McGuire Units 1 and 2, Indian Point Unit 3, Point Beach Units 1 and 2, Salem Unit 1, Seabrook Unit 1, Sequoyah Unit 1, South Texas Units 1 and 2, Summer Unit 1, Vogtle Units 1 and 2, and Wolf Creek Unit 1.

- PT Ratio is from Attachment "1"
- 3. Assumptions 3.1. The undervoltage relays are located in the turbine building, Area "A" elevation 119' in the 4KV switchgear room [FLOC]. The normal operation profile in this room is specified to be within 39 0 F(3.9 0 C) to 104 0 F(40 0 C) [Ref. 12.1.10]. Following a high energy line break, the maximum temperature in the 4KV switchgear room is calculated to be 95.3 0 F(35.20 C)
[Ref. 12.1.55 & Attachment 7]. Therefore, for the purpose of calculating the temperature effect on these relays the upper limit of 95.3 0 F(35.2 0 C) will be used. The DCM T-20 lower temperature limit of 39 0 F(3.9 0 C) is based on lowest ambient temperature recorded'from 1973 to 1982. Since the 4KV switchgear room is sufficiently isolated from outside environment and the relays are located in cabinets with energized components, it will be assumed that the lowest temperature these switches are exposed to is 50°F(10 0 C). The range of extreme temperatures for these switches is 95.30 F(35.2 0 C) - 50 0 F(10 0 C) =
45.3 0 F(25.20 F).
3.2. Basler does not specify a temperature effect for the BE1 relays for both the undervoltage and timing functions. Since the relays are located in a mild environment [see paragraph 3.1], it will be assumed that relay reference accuracy includes any temperature effect.
3.3. Maintenance Procedure MP E-50.61 [Ref. 12.1.6] was written for the old style 27H*T1 relays Basler BE1-27. The new ABB 27N relays do not have a maintenance procedure yet however it will be assumed that the same measurement and test equipment used to calibrate in MP E-50.61 will be used to calibrate the voltage dropout and pickup functions of the new ABB 27N relays. In addition the ABB 27N relays will have a time delay function that must be calibrated. It is assumed that the M&TE specified in MP E-50.30B
[Ref. 12.1.5] for calibrating the time delay of Agastat ETR relays will be used.
3.4. Maintenance Procedure MP E-50.33A [Ref.12.1.4] was written for the old style 27H*T2, 27H*B3 and 27H*B4 relays Westinghouse SSV-T. The new ABB 59N relays do not have a maintenance procedure yet. However it will be assumed that the same measurement and test equipment used to calibrate in MP E-50.33A will be used to calibrate the voltage dropout and pickup functions of the new ABB 59N relays. In addition the ABB 59N relays will have a time delay function that must be calibrated. It is assumed that the M&TE specified in MP E-50.30B [Ref. 12.1.5] for calibrating the time delay of Agastat ETR relays will be used.
3.5. Maintenance Procedure MP E-50.30B [Ref. 12.1.5] was written for the old style 62H*3A and 62H*3B relays Agastat ETR. The new ABB 62T relays do not have a maintenance procedure yet. However it will be assumed that the same measurement and test equipment used to calibrate in MP E-50.30B will be used to calibrate the time delay functions of the new ABB 62T relays.

The ABB 27N and 59N relays are not currently in use at DCPP. Hence drift data is not available from calibration records. In addition ABB does not publish drift values for these relays. Per CF6.NE1 [reference 12.1.1] Appendix 8.2 Section 2.3 in absence of calibration data and vendor published drift values, the default drift value to be used is
+/-2% of sensor span. Setpoints for ABB 27N and 59N relays are set using a combination of a fixed tap resistor and a potentiometer which is common for all available taps
[reference 12.1.51]. ABB was contacted to provide the setpoint span for each tap setting of these relays. ABB performed limited testing on one ABB 27N relay [reference 12.1.57].
The results support the assumption that the potentiometer allows for setpoint adjustment of -12% to +5% of tap setting. Due to the similarity between ABB 27N and 59N relays, a preliminary assumption will be made to apply this setpoint span to both the ABB 27N and 59N relays. This span will be used in calculating the default drift values per CF6.NE1.
The assumption will be validated via future testing by the DCPP maintenance department on both the 27N and 59N models to be used at DCPP. This testing is tracked to completion by SAP order 68012804 operation 150 and is required prior to return to service.
3.7. The ABB 27N and 59N relays allow for setting the Dropout (Actuate) setting as a percentage of the Pickup (Reset) setting. This calculation will specify~a setpoint for the dropout setting and the pickup will be calculated as a percentage of the dropout setting.
Accordingly, this calculation assumes that the uncertainty impacts the dropout setting and that the dropout and pickup settings will drift together in the same direction and not independently of each other.
- 4. Inputs 4.1. Basler BEl-GPS100 Reference Accuracy for undervoltage function: +/-2% of reading or
+/-1V whichever is greater [Ref. 12.1.50]. The use of 1V reference accuracy for the 127P and 27X devices will result in an over conservatism. Inspection of the historical As-Left calibration data shows that the 127P and 27X devices of these relays have been calibrated well within +/-0.3V and +/-0.2V respectively. To be conservative but not overly conservative only the +/-2% reference accuracy will be used in this calculation.
4.2. Basler BEl-GPS100 Reference Accuracy for time delay function: +/-5% or +/-3 cycles whichever is greater [Ref. 12.1.50]. Three cycles translate to 0.05 seconds (3c / 60c/S).
4.3. ABB 27N and 59N Reference Accuracy for undervoltage function: +/-0.1% of pickup and dropout settings [Ref. 12.1.51].
4.4. ABB 27N and 59N Reference Accuracy for time delay function: +/-10% or +/-20ms whichever is greater [Ref. 12.1.51].
4.5. ABB 62T timer reference accuracy: +/-0.5% or +/-15ms or +/- 1 digit of setting (whichever is greater) [Ref.12.1.52].
4.6. To calibrate the Basler BE1-GPS100 undervoltage function, an AC Voltmeter, 0-150V range, with accuracy of +/-(0.06% of reading + 0.03% of range) [Ref. 12.1.7] is used.
Range of the HP 34401A is 1 to 750 VAC [Attachment 6].
4.7. To calibrate the ABB 27N, 59N & BE1-GPSl00 time delay function, Manta MTS-1710 Advanced Universal Protective Relay Test System is used [Ref. 12.1.6 & 12.1.7]. The accuracy of this test equipment for a 0-9.9999 sec scale is:
M&TE = +/-0.5 mSec +/-1 least significant digit = +/-0.0006 sec For all other scales it is:

CALCULATION NUMBER: 9000041128 REVISION: 1 PAGE 19 OF 152 CALCULATION TITLE: 4.16 kV Bus FLUR & SLUR Setpoint Calculation DATE: 03/22/2011 M&TE = +/-(0.005% of reading +1digit), 1 digit = 0.1 mS [Attachment 4].
4.8. To calibrate the ABB 27N and 59N undervoltage function an AC Voltmeter, range 0-150 VAC with accuracy of +/-(0.06% of reading + 0.03% of range) is used [Ref. 12.1.6]. Range of the HP 34401A is 1 to 750 VAC [Attachment 5].
4.9. To calibrate the ABB 62T Timers, it is assumed that similar to the existing calibration procedure, the new calibration procedure [Ref. 12.1.51 will provide the option of using either a Manta MTS-1710 Advanced Universal Protective Relay Test System or a timer with accuracy of 0.01% of elapsed time +10 mSec or better.
At 8.5 and 18.5 seconds setpoint the accuracy of the specified generic timer is:
MTE = +/-(0.01% X 8.5 + 0.010) = +/-0.011 Sec MTE = +/-(0.01% X 18.5 + 0.010) = +/-0.012 Sec These values are larger than the Manta test system calculated in section 4.7. For the purpose of conservatism, the uncertainty of a generic timer will be used for the M&TE effect for 62H*3A/B timers.
4.10. The ABB 27N and 59N relays equipped with harmonic filter have a temperature effect of
+/-0.4% over a temperature range of 500 F(10 0 C) to 104 0 F(40 0 C) (range of 54 0 F) [reference 12.1.51]. Per paragraph 3.1 it is assumed that the relays are exposed to a temperature range of 45.3 0 F. Therefore, the temperature effect should be scaled in accordance with reference 12.1.1, Attachment 8.2, section 5.5 as follows:
0.4%x (45.30F) = 0.33%
TE=+/- _ [54oF]
ABB does not specify a temperature effect for the Time Delay function of the 27N and 59N relays. Since the relays are located in a mild environment [see paragraph 3.1], it will be assumed that relay reference accuracy includes any temperature effect for the time delay function.
4.11. The ABB 62T relays have a temperature effect of +/-2%, +/-20ms or +/-1 digit (which ever is greater) over a temperature range of -40 F(-20 0 C) to 158 0 F(70'C) (range of 162 0 F)
[reference 12.1.52]. The I digit on a relay with a range of 0.01-9.99 seconds is equal to 10 milliseconds. On a 0.01 to 99.9 seconds range it is equal to 100 milliseconds.
Per paragraph 3.1 it is assumed that the relays are exposed to a temperature range of 45.30 F. Therefore, the temperature effect should be scaled in accordance with reference 12.1.1, Attachment 8.2, section 5.5 as follows:
2%x(45.3oF)- 0.6%
TE- = +/-[162oF]
At 8.5 and 18.5VAC setpoints, the temperature effects are respectively 51 and 111 milliseconds.
4.12. Basler GPS100 Relay: The vendor does not provide any information as to the control voltage effect. But it provides a spec for the 125vdc power supply which is capable to File Name: 9000041128 (357S) Rev 1.doc 6/22/2011

4.13. ABB 27N and 59N Relay: The vendor datasheet provides a repeat accuracy of 0.1% over the allowable dc control power range of 100-140 VDC. This value is independent of the manufacturer's reference accuracy. [Ref. 12.1.51]. ABB does not specify a control power range effect on the time delay feature of these relays. RME term is 0 for time delay.
4.14. ABB 62T: The vendor datasheet provides an accuracy of +/- 2% or +/- 15ms or +/- 1 digit (whichever is greater) over the allowable control power range of -20%, +10% of the nominal control voltage. [Ref. 12.1.52]. On a device with a range of 0.01 to 9.99 sec, the 1 digit translates to 10 milliseconds. On a 0.1 to 99.9 seconds range device, the 1 digit translates to 100 milliseconds. The 2% temperature effect at 8.5 seconds setpoint translates to 170 milliseconds and at a 18.5 seconds setpoint it translates to 370 milliseconds.
- 5. Methodology The following methodology is used in the determination of FLUR & SLUR Channel Uncertainty (CU), setpoints (STP) and Acceptable As-Found (AAF) values 5.1. Channel Uncertainty (CU) Methodology:
Determination of the relay actuation and time delay uncertainty (CU) is based on the following algorithm provided in Reference 12.1.1.
pPMA2 + PEA 2
2
+SCA22 +SMTE 2 +SD 2 + STE 2 +SPE2 CU=EA+B+/- [ + Z[ RCA + RMTE + RD, + RTE* +RME2]
The above equation however is customized for each application as follows:
EA: The EA term is associated with the environmental allowance following a design bases accident. Since, the relays are located in the switchgear room in the fuel handling building and the environmental condition following LOCA and HELB is enveloped by plant normal conditions, the EA term will be removed from the above equation.
PEA: This term is associated with flow metering devices. Therefore it will be removed from the above equation.
SCA, SID, SMTE, SPE & STE: The relays will be treated as rack components and the uncertainty terms associated with the sensor will be removed.
PMA: Since error associated with the measurement of line voltage is treated as bias due to burden effect on the instrument potential transformer, the PMA term will be removed.
RME: The only potential miscellaneous effect is the effect of control voltage variation on the relay function.

CALCULATION NUMBER: 9000041128 REVISION: 1 PAGE 21 OF 152 CALCULATION TITLE: 4.16 kV Bus FLUR & SLUR Setpoint Calculation DATE: 03/22/2011 For the purpose of this calculation the above equation will be modified for both the actuation and time delay as follows:
2 2 2 2 CU = +/-(VIRCA2 + RMTE + RD + RME + RTE CU = Channel Uncertainty - The total uncertainty of an instrument channel.
This is the minimum allowable difference between the design value and the nominal setpoint value.
RCA = Rack Component or "String" Calibration Accuracy.
RMTE = Rack Component or "String" Measuring and Test Equipment Uncertainty.
RD = Rack Component or "String" Drift or Stability.
RTE = Rack Component or "String" Ambient Temperature Effects.
RME = Rack Component or "String" Miscellaneous Effects.
5.2. Coincident Logic Considerations (Dropout)
The channel uncertainty will be calculated at 95% probability of actuation. That means there is a 2.5% chance that the relay will actuate below "setpoint - uncertainty" and 2.5%
chance that the relay will actuate at above "setpoint + uncertainty". Therefore, at the point of concern which is the lower limit, there is 97.5% chance that the relay will actuate above "setpoint - uncertainty". Calculation of the point at which there is 95% probability that both relays will actuate is easier for SLURs because they are both ABB 59N relays with the same mean and standard deviation of error.. For SLUR dropout, when both relays have to actuate to initiate the timers, the probability of both timers to actuate above the lower limit is 97.5% X 97.5% = 95%. Therefore, the two sided random channel uncertainty calculated at 95% probability will correspond to 95% single sided uncertainty of a coincident logic. Therefore, for SLUR relays further scaling of uncertainty will not be required.
The setpoints of FLUR undervoltage relays for load shed; T1A, B, C & T2, have different Analytical Limit of actuation. T2 which is an instantaneous relay must actuate before the 4KV bus voltage reaches 3411VAC. But load shed will occur only if the bus voltage continues to degrade and further degradation is sensed by T1A, B or C undervoltage relays. The three T1 relays are setup in a voltage tier such that T1A will actuate at the highest voltage but will have the longest time delay of the three. T1 C will have the lowest actuation voltage and will have the shortest time delay. T1B is between the other two.
This has been configured such that it maximizes equipment protection against degraded voltage yet meets the criteria of the analytical limits.
Since the coincident logic for actuation of load shed has to wait till actuation of one of the T1 relays, the lower tail of uncertainty distribution of T1 setpoint will be at 97.5%
confidence level. The coincident logic will be based on the actuation of TIA.
Since the two sided T1A uncertainty is calculated at 95% CL (CUDo = 1.96Xa), the one sided actuation point with 95% probability will be equal to (1.645 X (7)Or in other words:
(1.645 / 1.96)

CALCULATION NUMBER: 9000041128 REVISION: 1 PAGE 22 OF 152 CALCULATION TITLE: 4.16 kV Bus FLUR & SLUR Setpoint Calculation DATE: 03/22/2011 For the pickup setpoint, the upper limit of uncertainty is of the interest. The calculated uncertainty of one relay will provide 97.5% probability that the relay will actuate below the upper limit. The probability that no relay will actuate above the "setpoint + uncertainty" is 2.5% X 2.5% = 0.0625%. On the normal curve, the "Z" value corresponding to 2.5% and 0.0625% are respectively 1.96 and 2.475. The upper limit of uncertainty for one out of two logic will be calculated by multiplying the upper limit of uncertainty by a factor of (1.96/2.475).
- 6. Acceptance Criteria 6.1. FLUR Acceptance Criteria 6.1.1. FLUR LOW VOLTAGE SETPOINT FOR DIESEL START (27H*B2): The 27X device in FLUR undervoltage relay detects a degraded voltage condition. The device 27X must actuate in less than 10 seconds before the 4KV bus voltage reaches Technical Specification limit of 2583VAC.
6.1.2. FLUR LOSS OF VOLTAGE SETPOINT FOR DIESEL START (27H*B2): The 27P device in FLUR undervoltage relay detects a loss of voltage condition. The device 27P must actuate in less than 0.8 seconds upon loss of voltage.
6.1.3. FLUR Degraded VOLTAGE SETPOINT FOR LOAD SHED (27H*T1A, 27H*T1B, 27H*TIC & 27H*T2): The coincident logic must actuate in less than 10 seconds before T1A senses a degraded voltage of 3328VAC on the 4KV bus. The coincident logic must actuate in less than 6 seconds before T1B senses a degraded voltage of 3120VAC on the 4KV bus. The coincident logic must actuate in less than 4 seconds before T1 C senses a degraded voltage of 2704VAC on the 4KV bus. However, T2 must actuate before T1A, B or C at a voltage above the analytical limit of 341 IVAC in preparation for T1 actuation.
6.2. SLUR Acceptance Criteria 6.2.1. The SLUR detects a degraded voltage condition less than or equal to 3785V on the associated 4160V Class 1E bus to protect motors from overheating.
6.2.2. If the degraded condition persists, the SLUR will initiate a diesel start signal within 10 seconds, 6.2.3. and then it will initiate bus load shed and transfer to diesel within 20 seconds. The time delays are provided by external time delay relays, devices 62H*3A and 62H*3B.
The SLUR scheme for each bus is comprised of two three phase 4160/120VAC potential transformers each supplying one SLUR. The SLUR output contacts, associated time delay relays, and various permissive contacts of other devices in the bus auto transfer scheme are supplied from the vital 125V DC System. One SLUR, device 27H*B3, is connected to the A-B phase PT and the other SLUR, device 27H*B4 is connected to the B-C phase PT. The SLUR contacts are connected in series such that both relays must dropout to initiate the diesel start and load shed time delay relays. Only one of the two SLURs is required to pick up in order to reset the diesel start and load shed time delay relays.

This limit is 91% of the nominal 4160V bus voltage and is equal to the analytical limit based on load flow calculation 357A-DC [Ref.
12.1.56]. The SLUR setpoint with all the uncertainties considered shall be higher than this limit.
SLUR Trip Avoidance Limit DCPP Calculation 357A-DC analyzes the availability of the offsite power source against normal operating transients. To prevent actuation of the SLUR during normal operating transients, the trip avoidance limit of the SLUR shall be less than or equal to 3850VAC.
SLUR Timers The SLUR load shed time delay should be adequate to maximize response time of LTC (Load Tap Changer) action to recover voltage. Currently the acceptance criterion for the third tap change is 16 seconds [Ref 12.1.8]. Therefore, the SLUR load shed time delay with all the uncertainties considered shall be higher than 16 seconds and lower than 20 seconds Technical Specification limit.

- 7. Body of Calculation 7.1. Potential Transformer Ratio Correction Factor (RCF)
The potential transformer consists of two single phase transformers. One transformer is connected to A-B phase and the other to the B-C phase. They are GE JVM-3 instrument transformer with a 35:1 turn ratio. FLOCs: DC-1/2-63-E-XF-SHF(G,H)12PT. The exact value of the PT ratio is dependent on the PT burden. The PT burden for transformers on each bus is calculated in Attachment "1". The transformer on A-B phase is lightly loaded while on the B-C phase is heavily loaded. Using the GE "Potential Transformer Characteristic Ratio and Phase Angle Curve" (Attachment "2"), the ratio correction factor (RCF) for lightly and heavily loaded transformers on each bus is tabulated as follows:

Bias (B)
The IR losses are considered to be negligible since the loop and associated cables are located in mild environments, and the currents are not sufficiently low so as to be comparable to leakage currents generated by extreme environmental conditions. As the PT and the degraded voltage relays are located within the same switchgear room, the voltage drop between the two devices can be considered negligible. No other source of bias term has been identified for the relay. Therefore, B=0 6/22/2011 File File Name: 9000041128 (3575)

The uncertainty at the lowest time delay setting per vendor reference accuracy is 20 milliseconds. This means that the pick up can occur anywhere between 80 to 120 milliseconds. Therefore, RCATD = +/-0.02 sec.
7.3.11. RCA - 27H*B3 Undervoltacqe Function Make-and Model: ABB Type 59N Dropout At 109.25VAC setting, the vendor reference accuracy per input 4.3 is:
VRFDo = +/-0.1% X 109.25 VAC = +/-0.11 VAC M&TE used to calibrate this relay cannot achieve the vendor reference accuracy. Hence the recommended ALDO tolerance is +/-0.5VAC. [See Section 7.4.11]
Per CF6.NE1 [ref. 12.1.1] Rack Calibration Accuracy (RCAuv) is the larger of VRFDo and ALDO. Hence:
RCAuvgo = +/-0.5VAC 7.3.12. RCA - 27H*B3 Time Delay Function Make and Model: ABB Type 59N Due to the use of the harmonic filter on the B2 relays, an instantaneous model cannot be used. Hence a definite time delay relay will be used with the time delay dialed to the minimum setpoint of 0.1 second. This time delay occurs on the pickup action of the relay.
Reference Accuracy for time delay function is +/-10% of setting or +/-20 ms whichever is greater [Ref. 12.1.51].
The uncertainty at the lowest time delay setting per vendor reference accuracy is 20 milliseconds. This means that the pick up can occur anywhere between 80 to 120 milliseconds. Therefore, RCATD = +/-0.02 sec.

7.3.14. RCA - 27H*B4 Time Delay Function Make and Model: ABB Type 59N Due to the use of the harmonic filter on the B4 relays, an instantaneous model cannot be used. Hence a definite time delay relay will be used with the time delay dialed to the minimum setpoint of 0.1 second. This time delay occurs on the pickup action of the relay.
Reference Accuracy for time delay function is +/-10% of setting or +/-20 ms whichever is greater [Ref. 12.1.51].
The uncertainty at the lowest time delay setting per vendor reference accuracy is 20 milliseconds. This means that the pick up can occur anywhere between 80 to 120 milliseconds. Therefore, RCATD = +/-0.02 sec.
7.3.15. RCA - 62H*3A Time Delay Function Make and Model: ABB 62T Per input 4.5, ABB 62T timer reference accuracy at 8.5 seconds time delay is
+/-0.5% or +/-1 5ms or +/- 1 digit of setting (whichever is greater).
VRFTD = +/-0.5% x 8.5 sec = +/-0.0425 sec. This is larger than 15ms or 1 digit which is 10 ms.
The M&TE is capable of calibration to a tolerance of 0.6 milliseconds [See Section 7.4.15]: Therefore for the purpose of conservatism a calibration tolerance of 50 milliseconds will be assumed.
Per CF6.NE1 [ref. 12.1.1] Rack Calibration Accuracy (RCATD) is the larger of VRFTD and ALTo. Hence:
RCATD = +/-0.05 sec.

+/-0.5% or +/-1 5ms or +/- 1 digit of setting (whichever is greater).
VRFTD = +0.5% x 18.5 sec = +/-0.0925 sec.
One digit of the setting corresponds to 100 ms. Since this is larger than the calculated VRFTD and larger than 15ms, VRFTD will be +/- 0.1 sec.
The M&TE is capable of calibration to a tolerance of 10 milliseconds [See Section 7.4.16]. Therefore for the purpose of conservatism a calibration tolerance of 100 milliseconds will be assumed.
Per CF6.NE1 [ref. 12.1.1] Rack Calibration Accuracy (RCATo) is the larger of VRFTD and ALTD. Hence:

Per section 5.2, CUFLURDO= +/-(1.645/1.96) X CU"HTI Since the T1 relays have lower setpoints than the T2, the 2/2 logic actuation is determined by the lowest bus voltage sensed by T1A at 3373V. This can be tested as follows:
The TIA 95% single sided voltage uncertainty is 0.75V X (1.645/1.96) = 0.63V T1A Trip Avoidance Limit = 96.5V + 0.63V = 97.13V T1A Trip Avoidance limit = 97.13V
- 34.951 = 3395V (81.61%)
The lowest T1A sensed voltage = 96.5 - 0.63 = 95.87V The lowest bus voltage = 95.87V
- 34.951 = 3351V The T1A 95% single sided time delay uncertainty is 1.02s X (1.645/1.96) = 0.86 Maximum time delay = 8.0 s + 0.86 = 8.86s.
The T1B 95% single sided voltage uncertainty is 0.72V X (1'645/1.96) = 0.60V T1 B Trip Avoidance Limit = 90.50V + 0.60V = 91.1 OV T1 B Trip Avoidance limit = 91.1 OV
- 34.951 = 3184V (76.54%)
The lowest T1 B sensed voltage = 90.5 - 0.60 = 89.90V The lowest bus voltage = 89.90V
- 34.951 = 3142V The T1 B 95% single sided time delay uncertainty is 0.72s X (1.645/1.96) = 0.60 Maximum time delay = 5.0 s + 0.60 = 5.60s.
The TI C 95% single sided voltage uncertainty is 0.69V X (1.645/1.96) = 0.58V TiC Trip Avoidance Limit = 78.60V + 0.58V = 79.18V T1C Trip Avoidance limit = 79.18V
- 34.951 = 2767V (66.52%)
The lowest T1 C sensed voltage = 78.6 - 0.58 = 78.02V The lowest bus voltage = 78.02V
- 34.951 = 2727V The TI C 95% single sided time delay uncertainty is 0.53s X (1.645/1.96) 0.44 Maximum time delay = 3.0 s + 0.44 = 3.44s.

Analytical Limits (AL) 7.11.1. 27H*T1 A (Time Delayed) Low Voltage The analytical limit for the time delayed initiation of load shed is established at 3328VAC (-80% bus voltage) within 10 seconds. There is no analytical limit for relay pickup. The 80% limit at 10 seconds is selected to ensure the motors will start and if they are running their protection relays will not trip prior to shedding the bus. This ensures availability of the motors during an accident.
7.11.2. 27H*T1B (Time Delayed) Low-Low Voltaqe The analytical limit for the time delayed initiation of load shed is established at 3120VAC (-75% bus voltage) within 6 seconds. There is no analytical limit for relay pickup. The 75% limit at 6 seconds is selected to maximize the time needed for voltage recovery without tripping the motor ov er load protection prior to shedding the bus. This ensures availability of the motors during an accident.
7.11.3. 27H*T1C (Time Delayed) Loss of Voltage The analytical limit for the time delayed initiation of load shed is established at 2704VAC (-65% bus voltage) within 4 seconds. There is no analytical limit for relay pickup. The 65% limit is selected to allow for clearing of a temporary fault and successful bus transfer to offsite power during a loss of voltage event.
This prevents spurious transfers to diesel generators during availability of offsite power.
7.11.4. 27H*T2 (Instantaneous)
The analytical limit for the instantaneous initiation of load shed is established at 3411 VAC (-82% bus voltage). There is no analytical limit for relay pickup.
7.11.5. 27H*B2 (Time Delayed)
The 27H*B2 relay has two diesel start analytical limits for "LOW voltage", and "LOSS of Voltage" and one diesel start nominal setpoint at "LOW-LOW Voltage". The "LOW' diesel start analytical limit is 2583VAC (-62% bus voltage) within 10 seconds [Ref. 12.1.2]. The "LOSS of Voltage" diesel start analytical limit is OVAC within 0.8 seconds. The "LOW-LOW Voltage" nominal setpoint is established at bus voltage of 1070VAC (-26% bus voltage) within 1.9 seconds. There is no analytical limit for relay pickup.
7.11.6. 27H*B3 & B4 (Initiate Timer)
The analytical limit for second level voltage protection is established at 3785VAC (-91% bus voltage) [Ref. 12.1.3]. The pickup should occur at a voltage below the worst case 4KV bus voltage CWP pump starts. This level is established at 3866 VAC in Ref. 12.1.56.
7.11.7. 62H*3A (Timer)
The analytical limit for time delayed diesel start is established at 10 seconds

The standard deviation of uncertainty = 27.36/1.96 = 13.96V The highest B4 dropout voltage is related to Bus "G" with a setpoint of 3855V and an uncertainty of 27.63V (0.78V*35.287). The standard deviation of uncertainty =
27.63V/1.96 = 14.10V Since both relays must actuate for the dropout function, we have to find the highest voltage at which there is more than 5% probability that both relays will actuate. Graphically under the normal distribution curve, the product of Area "A" and "B" should be less than 0.05.

Z = (3840-3818) / 13.96 = 1.58 This "z" value corresponds to 5.71% probability At 3840V the probability of B4 actuating is:
Z = (3840 - 3855) / 14.10 = -1.06 Since the Z value is negative, the probability will be 50% + (50% - probability of absolute value of Z value 1.06).
This "Z" value corresponds to 14.46% probability Hence the probability of B4 actuating at 3840 is 50% + 50% - 14.46% = 85.54%

Per assumption 3.7, the ABB 27N and 59N relays allow for setting the Dropout (Actuate) setting as a percentage of the Pickup (Reset) setting. This calculation has taken the position of calculating a setpoint for the dropout of the relays and the pickup will be calculated as a percentage of the dropout setting. Accordingly, this calculation assumes that the uncertainty impacts the dropout setting and that the dropout and pickup settings will drift together in the same direction and not independently of each other. Hence there will be no additional uncertainty applied to the pickup setting.
Reset of the FLUR Load Shed will only occur once 27H*T1A has reset. Since the reset of 27H*T1A will be set as a percentage of the dropout, it is conservative to assume the highest dropout voltage for 27H*T1A.
Highest dropout = 96.5 + .75VAC = 97.25VAC The dropout will be set at 99% of the pickup setting. Hence pickup will be:
Highest pickup = 97.25VAC / 99% = 98.24VAC This corresponds to a bus voltage of 98.24 x 34.951 = 3433VAC The highest bus voltage that a reset will occur by a T1A device is 3433V or 82.52%.
Reset of the FLUR Load Shed will only occur once 27H*T1 B has reset. Since the reset of 27H*T1 B will be set as a percentage of the dropout, it is conservative to assume the highest dropout voltage for 27H*T1 B.
Highest dropout = 90.5 + .72VAC = 91.22VAC The dropout will be set at 99% of the pickup setting. Hence pickup will be:
Highest pickup = 91.22VAC / 99% = 92.14VAC This corresponds to a bus voltage of 92.14 x 34.951 = 3220VAC The highest bus voltage that a reset will occur by a T1 B device is 3220V or 77.41%.
Reset of the FLUR Load Shed will only occur once 27H*T1C has reset. Since the reset of 27H*T1 C will be set as a percentage of the dropout, it is conservative to assume the highest dropout voltage for 27H*T1 C.
Highest dropout = 78.6 + .69VAC = 79.29\VAC The dropout will be set at 99% of the pickup setting. Hence pickup will be:
Highest pickup = 79.29VAC / 99% = 80.09VAC This corresponds to a bus voltage of 80.09 x 34.951 = 2799VAC The highest bus voltage that a reset will occur by a T1 C device is 2799V or 67.29%.

SLUR Diesel Start & Load Shed Reset The setpoints for SLUR undervoltage relays (27H*B3 & 27H*B4) are selected such that the corresponding bus voltage will be as close to each other as possible. Therefore, in calculating the "1-out-o-2" logic, a voltage must be selected that the probability of at least one relay resetting will equate to 95%. This is accomplished using the following procedure:
(1) The setpoints both at the relay and corresponding voltages on the bus, channel uncertainty and pickup ratio are tabulated in the following tables.
(2) The expected average reset is equal to the device setpoint divided by the average pickup ratio for that device.
(3) The highest reset is related to the uncertainty associated with the pickup ratio.
In the previous revision of this calculation an uncertainty of 0.59% was calculated for the existing Westinghouse hardware. In this calculation, for the purpose of conservatism an uncertainty of 0.7% will be assumed for the new ABB relay.
(4) For each pair of devices a voltage is selected. The difference between this selected value and the highest reset voltage calculated in step 3 divided by the standard deviation of uncertainty will provide us with the "Z" value for the standard Gaussian table. The calculated uncertainty of the drop out (CUDO) is calculated at 95% confidence level for a two sided distribution (i.e.; 1.96 X T).
The standard deviation of error is calculated for each device by dividing the dropout uncertainty by 1.96.
(5) Using the standard Gaussian distribution table the probability for each 'T" value is obtained. The probability of each device not resetting is the area under normal distribution curve corresponding to this "Z" value. The probability of each device not resetting is calculated. The probability of neither devices resetting is the product of the probability of each device not resetting. The selected voltage will be adjusted till the probability of neither device resetting is less than 5%. The probability of at least one device resetting is equal to one minus this latter value.
The result of the above procedure is tabulated in the following tables:

- 10. Conclusion 10.1. The FLUR dropout undervoltage and time delay setpoints adequate margin from TS allowable values [Acceptance criteria 6.1].
10.2. The SLUR dropout undervoltage and time delay setpoints provide adequate margin from TS allowable values [Acceptance criteria 6.2].
10.3. The adequacy of SLUR and FLUR to protect vital 4kV motors from tripping on an undervoltage event will be evaluated in calculation 170-DC.
10.4. The adequacy of SLUR dropout setpoint to prevent unnecessary and spurious actuation of protection system shall be evaluated in calculation 359-DC.
10.5. The impact of highest SLUR reset voltage on ability to maintain connection to offsite power source will be evaluated in 357A-DC [Ref. 12.1.56].
10.6. The adequacy of diesel generator time delay shall be evaluated in calculation 357A-DC.
10.7. The maximum time of 16 seconds established as the acceptance criteria for the load tap change in sections 7.3.8 and 7.5.8 of the electrical maintenance procedure MP E-62.3
[Ref. 12.1.8] provides more than 95% probability that the SLUR will not actuate before voltage is recovered by the load tap changer. The SLUR timer uncertainty is 0.54 sec.
The standard deviation of uncertainty = 0.54 sec /1.96 = 0.28 sec. The margin between the nominal setpoint of 18.5 seconds and 16 seconds LTC acceptance criteria is 1 sec or equal to 8.93Z (Z = [18.5 sec-16 sec] / stdev). Based on standard normal distribution table, the 8.93Z corresponds to < 0.01%. This means there is greater than a 99.99%
probability that the SLUR will not actuate before completion of the third load tap change.

- 11. Impact Evaluation
.11.1. The change in FLUR Analytical Limits will require a change to Technical Specifications Surveillance Requirements SR 3.3.5.3 as well as the Technical Specification Bases. This change is currently being tracked by notification 50301167 Task 13 and will require submittal of an LAR.
11.2. MP E-50.33A requires revision to remove the FLUR's and SLUR's from the scope of this procedure. The FLUR's and SLUR's will no longer use SSV-T relays hence this procedure no longer applies to them. This is being tracked by Order 68012804 Operation 30.
11.3. MP E-50.61 requires revision to remove the 27H*T1 relays from the scope of this procedure.
The "TI" relays will not longer use Basler BE1-27 relays hence this procedure no longer applies to them. This is being tracked by Order 68012804 Operation 40.
11.4. MP E-50.62: The Acceptable As-Found values established in this calculation are based on the historical performance of the undervoltage relays and timers. These values are more restrictive than those used in the calibration procedures. As-Found setpoints outside the limits established in this calculation could be early sign of relay degradation and should trigger performance monitoring at a higher frequency. This calibration procedure should be revised to reflect the Acceptable-As-Found values established in this calculation. This will be tracked by order 68012804 Operation 140.
11.5. STP M-75F, G & H require a complete revision based on the design change to the hardware as well as changes to setpoints and acceptable as-left tolerences via this calculation. This will be tracked by order 68012804 Operation 50.
11.6. STP M-13F, G & H require revision based on the design change to the hardware as well as changes to setpoints and acceptable as-left tolerences via this calculation. This will be tracked by order 68012804 Operation 60.
11.7. Calculation 359-DC must be evaluated for impact. Order 68012804 Operation 70 has been created to track evaluation of potential impact on calculation 359-DC.
11.8. Calculation 357R-DC shall be superseded by this calculation. Order 68012804 Operation 80 has been created to track voiding this calculation.
11.9. Calculation 357A-DC must be evaluated for impact. Order 68012804 Operation 90 has been created to track evaluation of potential impact on calculation 357A-DC.
1.1.10. Calculation 170-DC must be evaluated for impact. Order 68012804 Operation 100 has been created to track evaluation of potential impact on calculation 170-DC.
11.11. FSAR section 8.3 will require revision based on the changes in design and per this calculation. Order 68012804 Operation 110 has been created to track revision FSAR Section 8.3.
11.12. DCM T-18 will require revision based on the changes in design and per this calculation.
Order 68012804 Operation 120 has been created to track revision to DCM T-18.
11.13. DCM S-63 will require revision based on the changes in design and per this calculation.
Order 68012804 Operation 130 has been created to track revision to DCM S-63.

SUMMARY
DCPP does not currently have calibration data for the ABB 27N. In addition ABB does not publish drift values for the ABB 27N series of relays. Per CF6.NE1 [Reference 12.1.1] section 2.3, in the absence of vendor supplied drift data or calibration data, sensor drift value will default to +/-2.0% of span. For the ABB 27N series of relays, the pick-up setting is first selected using a combination of a voltage tap and a potentiometer [Reference 12.1.51]. ABB was contacted to determine the range of the potentiometer for each tap setting. ABB tested one 27N relay at the 70V, 80V and high end of the 120V tap [Reference 12.1.57]. The conclusions of this test determine that the potentiometer allows a span of -12% of tap setting and +5% of tap setting. Hence this calculation assumes [Assumption 3.6] that the range is established as such. In addition the dropout voltage is set as a percentage of the pick-up voltage. This calculation will specify a setpoint for the dropout setting and the pickup will be calculated as a percentage of the dropout setting. Accordingly, this calculation assumes that the uncertainty impacts the dropout setting and that the dropout and pickup settings will drift together in the same direction and not independently of each other.
[Assumption 3.7]. For this calculation pickup uncertainty will not be a factor.

Due to the similarity in the 27N and 59N relay design, this calculation assumes
[Assumption 3.6] that the range for the 59N relays is established in the same manner as the 27N relay. In addition the dropout voltage is set as a percentage of the pick-up voltage. This calculation will specify a setpoint for the dropout setting and the pickup will be calculated as a percentage of the dropout setting.
Accordingly, this calculation assumes that the uncertainty impacts the dropout setting and that the dropout and pickup settings will drift together in the same direction and not independently of each other.

Time Delay Drift 62H*3A Relays: +/-0.17 Sec Time Delay Drift 62H*3B Relays: +/-0.37 Sec ANALYSIS Time Delay Drift:
Per Reference 12.1.52, ABB 62T relays are solid state digital timers. The time delay is available with a 0.001-0.999 second range, 0.01-9.99 second range, 00.1-99.9 second range and a 001-999 second range.
The 62H*3A relays will use the 0.01-9.99 second range. However since the setpoint is set using thumbwheels in a digital circuit, the drift only applies to the oscillator circuit for the duration of the timing.
Hence the span considered for drift will only be from 0 to the 8.5 sec setpoint.
Per the guidance of CF6.NE1 the Time Delay Drift value for a 30 month calibration period is assumed to be 2% of the span between 0-8.50 seconds or 0.17 seconds.
The 62H*3B relays will use the 0.1-99.9 second range. However since the setpoint is set using thumbwheels in a digital circuit, the drift only applies to the oscillator circuit for the duration of the timing.
Hence the span considered for drift will only be from 0 to the 18.5 sec setpoint.
Per the guidance of CF6.NE1 the Time Delay Drift value for a 30 month calibration period is assumed to be 2% of the span between 0-18.50 seconds or 0.37 seconds

Uncertainty Due to Human Reaction Time To understand the effect of human reaction time on stopwatch and timer calibration uncertainties, a small study was conducted. Four individuals were selected, and asked to calibrate a standard stopwatch using the Direct Comparison Method. Two separate experiments were conducted. In the first experiment, the operators were asked to use a traceable audio thie signal, and in the second experiment, the operators were asked to use a traceable time display. The time base of the stopwatch was measured before and after each test (using the Time Base Method), and its offset firom nonminal was found to be small enough that it would not influence the test. Therefore. differences in readings between the stopwatch being tested and the standard would only be due to the operator's reaction time.
Each operator was asked to repeat the measurement process ten times.
and the resulting difference between the standard and the stopwatch were recorded and plotted (Figure 14).
As shown in Figure 14, the average reaction time was usually less than +/-100 ms, with a worst-case reaction time exceeding 700 ins.

CALCULATION NUMBER: 9000041128 REVISION: 1; LEGACY NUMBER: 357S-DC PAGE 136 OF 152 ATTACHMENT "7" The mean and standard deviation for each operator was computed and graphed in Figure 15. This graph indicates that the average (mean) reaction time of the operator can be either negative (anticipating the audible tone) or positive (reacting after the audible tone). Figure 15 also shows that in addition to the average reaction time having a bias, the data is somewhat dispersed, so both elements of uncertainty will need to be accounted for in a complete uncertainty budget. For this experiment, the worst case mean reaction time was 120 ms and the worst case standard deviation was 230 ins. It should be noted that in the measurements recorded in Figure 15, Operators 1 and 2 had no previous experience calibrating stopwatches. Based on these results.
it is reconunended that each calibration laboratory perform tests to determine their operator reaction time uncertainty value.

When a traceable time display was used, the uncertainty due to lunnan reaction time was foutd to be approximately the same as the human reaction time for an audible tone. Keep in mind that the data presented here is presented to illustrate the nature of uncertainty due to human reaction time and to provide a very rough estimate of its magnitude.
We strongly encourage each person perforning stopwatch and tinier calibrations to perform repeatability and reproducibility experiments to determine the uncertainty due to humnan reaction time for the specific calibration method used by the laboratory.

Short Circuit, and Motor Starting Calc No. 357A-DC Rev. 12 Unit: 1&2 approach to ensure adequate voltage when backfeeding from the 500 kV grid is to check 4 kV and 480 Volt bus voltages if the grid drops below 514.5 kV (98 percent) or goes above 535.5 kV (102 percent) (Ref. 12.2.12). The 4 kV vital buses should be maintained above 3.866 Volts (92.93 percent, SLUR trip avoidance limit, Ref. 12.1.2f) and 480 Volt motor control centers should be below 506 Volts to ensure 460 Volt loads are not subjected to overvoltage during lightly loaded conditions. Motor control center voltages above 511 Volts will result in overvoltage on control power transformer 120 Vac circuits.
Steady state voltages throughout the distribution system via the StartUp source are acceptable for 230 kV grid voltage range of 207-241.5 kV. The evaluation of transient effects associated unit trip and bus transfer schemes is addressed in Reference 12.2.1.
A 4 kV bus should not be aligned to the Startup source with the corresponding LTC in automatic at the elevated setpoint. except for as allowed in Reference 12.2.10.
The StartUp Buses shall not be paralleled while supplying any Reactor Coolant Ptumps due to the potential loss of adequate containment penetration protection.
Any motor can be started via the Aux offsite source without initiating a SLUR under voltage diesel generator start. Starting a 12 kV motor via the StartUp source may cause the diesels associated with that Unit to start. Diesel starting can be precluded by placing the associated LTC in manual and adjusting the StartUp Bus voltage to 12.48 kV (i.e.
104 percent) prior to starting the motor. This starting configuration relies on the insertion of one 230 kV capacitor bank.
Condensate Train 11 was satisfactorily started via the StartUp source with the LTC in manual. Condensate Train 11 is fed from the same StartUp transformer winding that feeds the vital buses. Therefore. any one of the condensate trains could be started. The SLUR protective fimction reset before the diesel generators started. The simulated loading for the Condensate Pump was 1112 bhp (i.e. 89 percent of the motor rating.
normal operating load). The Booster Pump was loaded at 2580 bhp (i.e. 86 percent of the motor rating. normal operating load). This represents a combined starting load of 3692 hp. wvhich exceeds the combined load of 1430 hp that could be sequenced on automatically while the plant is in Modes 5 or 6 (i.e. 2 ASW pumps @465 hp plus 5 CFC Units @100 hp, Ref. 12.1.1c. Table 4.3-1). Therefore, during plant Modes 5&6 and all buses aligned to StartUp (i.e. no potential automatic bus transfers), it is acceptable to have the LTC in manual provided the selected tap yields nominal StartUp Bus voltage.

SUMMARY
The dropout setpoint is adjustable for the 27H*T1A, B, C, 27H*T2, 27H*B3 and 27H*B4 relays. For the 27H*B2 relays the dropout point is a function of the setpoint. Hence the dropout point for the 27H*B2 relays will be determined using the concept of a dropout ratio. The dropout ratio will be determined using historical calibration data and the analysis described below. The average and lowest undervoltage dropout ratio are summarized below at 95% confidence limit:

Calculation 357S-bC (SAP 9*41128) El I]2 [K1&2 1 Briefly describe what is being changed and why:
Notification 50301167 identified a degraded condition with the vital 4.16 kV bus under-voltage protective relays and timers These relays are also known as the FLURs and SLURs. As a result the protective relaying scheme is being modified with new relay hardware and setpoints for both Unit 1 and 2 to implement better under-voltage protection. The change requires the development of a new setpoint and uncertainty calculation to supersede the existing 4.16 kV bus under-voltage protective relay calculation 357R-DC. The changes are defined as follows:
- 1. Supersede calculation 357R-DC which establishes setpoint bases and allowable values for the existing 4.16kV bus under-voltage protective relaying.
- 2. Create a new calculation 357S-DC which establishes new setpoint bases and allowable values for the new 4.16kV bus under-voltage protective relaying design as follows:
- a. Replace first level undervoltage load shed relay 27HxT1 with three relays each with a voltage and time delay setpoint.
- b. Replace first level undervoltage instantaneous load shed relay 27HxT2 with a new more accurate relay and new undervoltage setpoint.
- c. Replace second level undervoltage voltage sensing relays 27HxB3 and 27HxB4 with new more accurate relays and new undervoltage setpoints.
- d. Replace second level undervoltage time delay relays 62Hx3A and 62Hx3B with new more accurate relays and new time delay setpoints.
- 3. Establish new tech spec limits for 27HxT1A, B & C relays and 27HxT2 relays.
- 4. Administrative change: Bring all existing information and calculations related to the bus transfer and diesel start relay 27HxB2 from superseded calculation (357R-DC) to the new calculation (357S-DC).
Revision 1 of this calculation has been performed to correct a TYPO on page 16 of this calculation. Specifically the summary of set points for the TIA relays listed the nominal time delay set point as 7 seconds as opposed to the required 8.
- 2. Applicability Determination (refer to TS3.1D2, Appendix 7.1 Section 2 for instructions) Ref.
