1.0 PURPOSE

The purpose of this calculation is to determine the adequacy of the voltage profiles for vital equipment in the power distribution system during de-graded grid conditions to meet the guidelines of Branch Technical Position PSB-1 (reference 4.4). Specifically, this calculation encompasses the voltage profiles for vital equipment during a probable worst case scenario which still allows the most reliable power source (offsite power} to remain in service. The scenario is described in section 2.2.

This calculation shall also determine the minimum allowable bus voltage at the 4.16 KV vital buses. This voltage shall be used to determine the "dropout" setpoint for the degraded grid relay. Refer to calculation S-C-4KV-JDC-959 for the de-graded grid relay setpoint. ~

This calculation shall also manifest, that while the diesel generators are operating under loaded conditions, the voltage at the 4.16 KV vital buses is greater than the 4.16 KV vital bus voltages during the worst case de-graded grid scenario. Therefore, this calculation shall be the governing document for worst case voltages at the vital buses.

1.1 Scope

This calculation is limited to the voltage profiles for equipment operating from the VITAL buses (4.16, 0.480, and 0.240 KV} at Salem Generating Stations (SGS} Units 1 & 2.

The MOVs operating from the vital buses are evaluated as part of PSE&G's 89-10 project, reference 4.8 and are not included in this study.

Control circuit voltage drops are evaluated in calculations ES-15.005 (Unit 1) and ES-15.006 (Unit 2).

1.2 Revision History

Calculation ES-15.008, Rev. 1 is being revised and superseded by Rev.2. Revision 2 performs the same analysis as Revision 1. However, this revision provides the analysis for the Salem Electrical Distribution Upgrade Project (SEDUP). The sequence of events remains the same. The differences between revision 2 and revision 1 are:

• the vital bu~es have separate transformers from the group buses. This prevents group bus loads from transferring onto the vital bus 13.8/4.16 KV electrical distribution system. Attachment 2, provides a simplistic one-line diagram of the SEDUP.

• for a worst case scenario one unit has its' group buses operating at full power from the Station Power Transformers (SPTs) 11(21) and 12(22). In revision 1, one unit was in startup/shutdown mode which has some of the group bus 4 KV motors deenergized to prevent overloading of the SPTs. In the new configuration the transformers are not overloaded, therefore for conservatism, when the group buses are operating from the SPTs, the unit is in Mode 1 (producing power) .

1. 3 Swmnary

As shown in the sununary tables for the voltage profiles (Attachment 3 & 4, description discussed in section 5), all the Vital motors required during a probable worst case scenario pass the voltage criteria discussed, in section 2.3.1, during motor starting and steady state conditions except the motor at node 26178. This motor is 2CHE7-MTRY, #22 Chilled Water Pump and the terminal voltage for this motor is O. 7969 pu. Engineering Evaluation S-C-EE-230-EEE-0790 "230 V MOTOR STARTING DURING A LOCA INl'l'IA'fl!;D BLOCK ST'AR'r 11

, has analyzed the capability for this motor to start at 0.743 pu. Therefore, the motor shall be capable of starting at 0.7969 pu ..

The minimum allowable bus voltage on the 4KV vital buses during eteci_dy st~.te conditions following o.n accident scenario is 0.94 pu as shown in column 15 of Attachments 3 & 4.

2.0 DESIGN BASIS /METHODOLOGY

2.1 Overview

The Salem Power Distribution System voltage profiles are primarily determined by transformer ratios, transformer impedances, cable impedances and plant loading. There are four 112 MVA 500/13.8 KV main transformers provided with + or - 5% no load tap changers. These transformers provide power to the eight 28 MVA 13.8/4.16 KV Station Power Transformers (SPTs). SPTs 3 & 4 normally s~~ply power to SPTs 13, 14, 23, & 24 which energize the vital and circulating water (CW) buses for Units 1 & 2. SPTs 1 and 2 normally supply power to SPTs 11, 12, 21, & 22 which energize the group buses during Startup/Shutdown or Abnormal conditions. If SPT 3 or 4 becomes inoperable, the 13 KV system is realigned so that SPT 1 or 2 energizes the appropriate Vital/CW bus SPTs only. The SPT (1 or 2) which is not supplying power to the vital buses shall energize all four group bus SPTs. This totally isolates the group buses from the vital buses below the 500 KV level. It also manifests the adherence to 10 CFR 50 Appendix A -General Design Criteria (GDC) 17. GDC 17 basically states the vital buses shall have two sources of offsite power available.

There are two auxiliary power transformers (APTs) which normally supply the eight group buses when the units are on line. Four group buses are for Unit 1 and four are for Unit 2. There is one 4.16/.48 KV and one 4.16/.24 KV transformer for each of the vital buses. Attachment 2, provides a simplistic diagram of the Salem Power Distribution System. Attachment 1 provides a description for the node numbering system used by the PSE&G Load Management System (LMS) which is described in a section 2.3 and 5.0.

The SPTs 11, 12 ,13, 14, 21, 22, 23, 24 and the APTs are equipped with load tap changers (LTCs) which are set to maintain 4200 volts minimum and 4300 volts maximum at the 4.16 KV vital and group buses. Also, Operation's procedure SC.OP-DD.ZZ-0023(Z) requires recording of the 4.16 KV bus voltages every 8 hours. If for any reason any of the vital buses are below 4200 volts the LTCs are placed in manual and the bus is maintained between 4200 and 4300 volts.

2.2 Design Basis

The branch technical position PSB-1 states 11 ••• the

analysis perf onned to detennine minimum operating voltages should typically consider maximum unit steady state and transient loads for events such as a unit trip, loss of cooling accident (LOCA), start up or shutdown; with the offsite power supply (grid) at minimum anticipated voltage ... " The basis for detennining the worst case voltage profile is described below:

1.0 The minimum operating voltage on the 500 KV grid is 1.05 pu on a 500 KV base. This is based on the letter from PSE&G Distribution Systems Department (reference 4.3, Attachment 8). -

2.0 The worst case alignment for the 13KV ring bus is when one unit has the group buses energized from the SPTs in Mode 1 and the other is operating at full power with the group buses on the APTs. At time t=O, a Safety Injection signal is initiated. This starts the sequence for the vital equipment as described in section 2.3.2. Also, upon an SI signal a reactor trip followed by turbine trip occurs and the generator is taken off line after 30 seconds. At this time, the group buses automatically fast transfer to the SPTs 11(21) and 12 (22).

For conservatism, the unit which is operating from the APTs is at maximum power consumption.

2.3 Methodology

The analysis is performed using PSE&G's Load Management System (LMS). The LMS uses PSSE software which was developed by Power Technologies Inc. (PTI) to provide voltage profiles during steady state and transient events. The command used('w{thin PSSE for this calculation is "FNSL". A description of the activity is provided in Attachment 5. This software is used in conjunction with the LMS database. The LMS database represents a model of Salem Generating Stations Units 1 and 2 electrical power distribution system from the 500 KV level to the 120 volt distribution panel level. The database provides the calculation software with all the information required to perform the analysis. For example:

Load Data

• Nameplate horsepower (HP), Brake HP, efficiency, power factor, and motor data, panel loads, heaters etc.

Branch Data

• cable types, lengths and impedances for 90 degree c.

Transformer Data

• transformer tap setting/ratios, rating, impedance based on taps and KVA rating, connection type (YY, d-Y, etc.) Tap step for the LTCs and maximum and minimum limits the LTCs can operate.

For all of the loads, status is provided. That is, whether the load is in service or out of service for a particular mode. For a more detailed description of the software, the database, and assumptions made in developing the database, see references 4. 6 and 4-. 7.

The LMS is arranged to match the existing plant configuration:

• The voltages at the group and vital buses are set to regulate at 1.01 pu of 4.16 KV.

• SPTs 1, 2, 3, & 4 have their no-load taps set at 5% buck.

• SPTs 11,12,21 and 22 have their no~load taps set at 2.5% boost and SPTs 13,14,23 and 24 ~at 5% boost.

• APTs 1 & 2 have their no-load taps set at nominal.

• All the 4.16/.48 KV and 4.16/.24 KV transformers have their no-load taps set to 2.5 % boost .

• Actual transformer impedances are used for all the station power transformers.

• For the 4.16/0.48 KV and 4.16/0.24 KV vital bus transformers, the impedances are based on worst case (highest) tolerances from reference 4.14.

• The vital 4.16, 0.48, and 0.24 KV buses are loaded based on References 4.12 and 4.13.

Accident Sequencing

Based on the Memorandum sent from J. Carey to M. Mortarulo on January 5,1993, the accident sequencing has been developed. This memo is provided as Attachment 6, reference 4.14. As noted in the memo, the 11(21) and 12(22) Containment Spray (CS) Pump will·only start if a containment pressure hi-hi signal is present. The setpoint for this signal is 15 psi and the basis is provided in Reference 4.16. Attachment 7 provides a containment pressure profile. From this graph, the time taken to reach 15 psi is 6.25 seconds. To be conservative this calculation starts the CS Pump in five seconds.

The Service Water (SW) Pump motors operate in the following manner: If either the primary or secondary SW Pump motor is operating and a LOCA signal is detected, the other motor is not energized. However, if neither motor is energized and a LOCA signal is detected the primary SW Pump

motor will start at t=O, if it does not start then the secondary motor is energized at t=5. To provide conservatism, this calculation assumes two SW Pump motors are energized on the same vital bus. When a LOCA signal is detected the other two primary SW motors will be energized at t=O. Therefore, the sequence for the service water Pump motors is as follows:

• Two SW Pump motors are energized on the 4.16 KV vital "B" bus.

NOTE: The "B" bus is chosen only because when two SW pump motors are energized on the "B" bus, the "B" bus is ':he most heavily loaded bus. However, with the voltages at all the 4.16 KV vital buses being at approximately 1.01 pu before an accident, the voltage drop due to starting of one SW pump motor per transformer will be approximately the same whether it is on the "B" or "C" bus.

• A SI signal is detected at t=O and the other two primary SW Pump motors (1/bus) will be energized.

This sequence will provide the worst case bus voltages during the LOCA starting transient.

For steady state conditions a fifth SW Pump motor is energized on the "C" bus to provide the worst case loading during steady state conditions.

At t=30 seconds the group buses transfer to the station power transformers, SPTs 11(21) and 12(22).

3.0 ASSUMPTIONS

1.0 The load tap changers are assumed to fail in position.

2.0 Assumptions made to model the database are provided in the PSE&G LMS PSBP 313581 Vol.2.

3.0 Not more than five Service Water Pump motors operate at one time

5.3 Results

The summary of the results of this calculation are provided in Attachments 3 and 4.

Attachment 3 and 4 Description:

Attachments 3 and 4 provide a summary table of the voltage profile study. The summary table is divided into basically 2 sections. One section, columns 1-9, is the calculated per unit bus voltage when an event happens, the other is the worst case motor under the three main events, Starting, Normal Steady State, and Abnormal Steady State which sets the 4KV vital buses to 0.94 pu. These three events have two columns each. Columns 10, 12 & 14 provide the worst case motor node number and columns 11, 13 & 15 provide the per unit motor terminal voltage on, the bus voltage base (top #) and the motor terminal base (bottom #) . Column 14 also provides the per unit voltage at the bus in parenthesis under the node number, when the 4KV vital buses are set to 0.94 pu. For the motor starting case, column 11, if a motor dropped below the criteria, the next worst case motor starting is provided until the criteria is met.

A detailed list for all motor rated voltages are provided in the LMS reference 4.7.

Attachment 9, provides a calculation for voltage drop from the 2A Diesel Generator to the respective 4.16 KV A bus if the generator was in service. This calculation shows the bus voltage to be 4141.8 volts or .9956 pu. This is above the worst case steady state 0.94 pu voltage at the 4.16 KV buses calculated by this study. Therefore, this calculation encompasses the steady state voltage criteria for vital equipment if the diesels were in service. The 2A diesel was selected because it has the longest cable between the diesel generator and its' respective 4.16 KV bus.

Power Technologies, Inc. PSS/E Program Operation Manual

• Activity: FNSL

•

•

FNSL,FS FNSL,OPT

Activity selector: Load flow

Function:

Activity FNSL applies the Newton Raphson load flow iteration to the network modelled in the working case. Bus voltages are adjusted until the convergence tolerance is reached, the iteration limit is exceeded, or activity FNSL is terminated with the "S AB" interrupt control code.

When no suffix is specified when invoking activity FNSL, the voltages in the working case are used as the initial voltage estimate. When selected with the "FS" suffix, all voltages are initialized to unity magnitude at zero phase.

Activity FNSL provides for the following automatic adjustments:

tap ratio adjustment phase shift angle adjustment area interchange control DC converter transformer adjustment switched shunt adjustment

The program option settings at the time activity FNSL is invoked determine which of these adjustments are activated. When invoked with the suffix "OPT", the user may override any or all of the present solution adjustment option settings as well as specify a "flat start".

Interrupt control codes:

AB - terminate activity FNSL following next completed iteration NC - suppress convergence monitor NM - suppress automatic adjustment monitors DC - print DC line conditions at each load flow iteration NV - suppress incorrect plant VAR limit report

Prerequisite:

The working case must contain a validly specified load flow case with voltages that are a reasonable estimate of a solution. If the previous attempt at solution has diverged or if the quality of the voltage estimates is unknown, a "flat start" should be

·specified.

Activity FNSL requires the determination of a sparsity preserving ordering of network buses via activity ORDR. If FNSL detects that the ordering needs to be determined, activity ORDR is automatically invoked prior to commencing the iterations of activity FNSL. .

MINIMUM OPERATING 500-KV BUS VOLTAGE LEVEL

DATE: August 21, 1992

As per your request, Transmission Planning conducted a study to determine the minimum voltage at the Salem 500-kV bus as a result of a degraded grid condition. The study showed the lowest voltage to be above 1.05 pu. This value is higher than that concluded in our previous analysis which was transmitted in a letter from J. D. Hebson dated November 19, 1987. The increase in the 500-kV bus voltage is attributed to the addition of 1200 MVAR of shunt capacitors on the PJM 500-kV grid, and approximately 3200 MW of utility and nonutility generation in New Jersey. Table 1 shows the list of the 500-kV capacitor additions, and Table 2 shows the generation additions in New Jersey.

The analysis base cases were based on the 1996 Crown Vista study base cases. Both peak and intermediate load levels were analyzed. The Crown Vista base cases were redispatched to force out Salem No. 1 and the Hope Creek units. In the peak load case, PJM imports were modeled at 2600 MW and New Jersey imports at 3800 MW. In the intermediate case, PJM was importing 3900 MW and New Jersey was importing 5000 MW. PSE&G was importing 1700 MW in the peak load case and 3200 MW in the intermediate load base case. Tables 3 and 4 show a summary of generation, load and interchange for the PJM pool and all member companies. Under normal operating conditions, the voltage at the 500-kV bus is maintained between 1.08 and 1.10 pu. In the analysis, the pre-contingency voltage at Salem 500-kV bus was modeled at 1.08 pu.

The most critical contingency tested was found to be the simultaneous loss of the Alburtis-Branchburg and the ElroyBranchburg 500-kV circuits and prior to any system adjustments, the remaining Salem unit was tripped. The loss of the Salem unit and the two 500-kV lines will force heavy flow over the Keeney, Hope Creek and Salem circuits, and will remove the reactive support given by the Salem unit. The post-contingency voltage at Salem 500-kV bus was 1.056 pu .

M. A. Mortarulo - 2 - 8/21/92

The next critical contingency was the loss of the Peach Bottom-Keeney 500-kV circuit and the trip of the remaining Salem unit prior to system adjustments. The post-contingency 500-kV voltage at Salem was 1.057 pu.

Both of the above critical contingencies exceed the MAAC and PSE&G planning criterias. Load flow transcriptions of the study base cases and the critical contingencies are shown in Exhibits 1 thru 12.

1.0 PURPOSE

The purpose of this calculation is to determine the adequacy of the voltage profiles for vital equipment in the power distribution system during de-graded grid conditions to meet the guidelines of Branch Technical Position PSB-1 (reference 4.4). Specifically, this calculation encompasses the voltage profiles for vital equipment during a probable worst case Design Basis Event (DBE) which still allows the most reliable power source (offsite power) to remain in service. The DBE is described in section 2.2.

This calculation shall also manifest, that while the diesel generators are operating under loaded conditions, the voltage at the 4.16 KV vital buses is greater than the 4.16 KV vital bus voltages during the worst case de-graded grid DBE. Therefore, this calculation shall be the governing document for the worst case voltages at the vital buses.

1.1 Scope

1.2

This calculation is limited to the voltage profiles for equipment operating from the VITAL buses (4.16, 0.480, and 0.240 KV) at Salem Generating Stations (SGS) Units_ 1 & 2.

The MOVs operating from the vital buses are evaluated as part of PSE&G's 89-10 project, reference 4.9 and are not included in this study.

Control circuit voltage drops are evaluated in separate calculations, ES-15.005 (Unit 1) and ES-15.006 (Unit 2) •

Revision History

Calculation ES-15.008, Rev. O is being completely revised and superseded by Rev.1. Rev. 0 provides an analysis for the equipment being operated from the 480 and 240 Volt vital buses when the 4.16 KV buses are operating at 91.6% of rated voltage or 3811 volts. The basis for the 91.6% is provided in the De-graded Grid relay set-point calculation S-C-4KV-JDC-959 and Calculation ES-15.011 "The Power Technologies Incorporated report PTI Rll-87".

Deficiency DES-92-0448 was written against Calculation ES-15.008 Rev. 0 about concerns regarding the basis for grid recovery, motor starting and whether strict adherence to PSB-1 was being maintained. This revision provides an accurate account of the voltage profile throughout an accident sequence during a probable worst case DBE. Revision 1 shall address all the concerns in deficiency DES-92-0448. These concerns are described in the summary, section 1.3

Summary

As shown in the summary tables for the voltage profiles (Attachment 3 & 4, description discussed in section 5), and the conclusion section 6.0, all the Vital motors required during a probable worst case DBE either pass the voltage criteria discussed, in section 2.3.1, or have been evaluated and determined to perform as required to meet their system requirements during a worst case DBE.

This analysis also concludes that the second level of undervoltage relay settings shall remain with a dropout setpoint of 91.6% and a reset value of 92.6%. This ensures the vital buses will remain energized from the most reliable power source (OFFSITE POWER) while still meeting all safety related concerns during a worst case DBE.

This analysis has also addressed all the concerns of deficiency DES-92-00448. These concerns were as follows:

• Revision O uses Engineering Evaluation s-c-zzxxEEE-0255 to justify the ability for the 460 and 230 volt motors which were of concern, provide their intended function during a worst case DBE. However, there is not an apparent basis or time for 500 KV grid recovery from 1.01 pu to 1.043 pu based on 500 KV as shown in the evaluation.

•

In this revision the 500 KV system starts at a the worst case degraded voltage of 1.05 pu and is assumed to remain at the worst case degraded voltage of 1.05 pu throughout the analysis.

Revision O provides an analysis for the 480 and 240 volt buses after the 500 KV grid has recovered

to 1.043 pu. However, there is not an apparent basis for allowing vital bus motors·on the 240 volt vital buses to operate below 90% steady state during the 500 KV recovery period.

In this.revision, the 500 KV grid is considered to remain at the lowest possible grid voltage throughout the DBE, therefore a 500 KV recovery period is not considered. The motors which operate below the criteria discussed in section 2.3.1 are evaluated in Engineering Evaluations S-C-230-EEE-0790 and S-C-230-EEE-0753.

Revision O starts with the 4.16 KV vital bus voltages at 91.6% of 4.16 KV. This is the dropout setting of the second level of undervoltage relay. However, all the vital motors do not pass the criteria as discussed in section 2.3.1 at 91.6% allowing vital bus motors on the 240 volt vital buses to operate below 90% steady state. From this observation is PSE&G in compliance with PSB-1?

This revision provides an analysis throughout the duration of a worst case DBE. The worst case recovery voltage has been determined to be 93.2% of 4.16KV. Because, we can take credit for the load tap changers, the worst case voltage is postulated to be the recovery voltage of 93.2%. This lowest voltage case is created by a LOCA on Unit 1 coincident with a Trip/Startup on Unit 2. After Unit 1 group buses have transferred and the transient is complete, the 4KV vital buses at Unit 1 recover to 93.2%. There is no credible scenario that would cause the voltage to be lower than 93.2%. Therefore, the lowest bus voltage evaluated is 93.2%. At this voltage level all the vital motors shall perform as required to meet their system requirements during a worst case DBE.

Engineering Evaluation S-C-230-EEE-0790 Rev. l"Motor Starting and Running During a LOCA Initiated Block start" has determined all motors analyzed in Attachment 10 (reason for analysis discussed in section 2.3.1) are capable of performing their required function during a DBE except the Auxiliary Building Supply Fans, 11, 12 21, & 22. Deficiency report DES-93-00157 has been generated to evaluate this situation and initialize any corrective action if required.

2.0 DESIGN BASIS /METHODOLOGY

2.1 Overview

The Salem Power Distribution System voltage profiles are primarily determined by transformer ratios, transformer impedances, cable impedances and plant loading. There are two 112 MVA 500/13.8 KV main transformers provided with + or - 5% no load tap changers. These transformers are known as SPT 1 and SPT 2 and provide power to the four 28 MVA 13.8/4.16 KV Station Power Transformers (SPTs). Two of these SPTs, SPT 11 and SPT 12 normally supply power to the vital buses from Unit 1 and the other two SPTs, SPT 21 and SPT 22 normally supply power to the vital buses from Unit 2. The Operation's Department allows the alignment of the vital buses from either SPT 11(21) or 12(22) as long as the SPT is not overloaded. There are two auxiliary power transformers (APTs) , APT 1 (unit 1) and APT 2 (unit 2), which normally supply the eight group buses when the units are on line. Four group buses are for Unit 1 and four are for Unit 2. There is one 4.16/.48 KV and one 4.16/.24 KV transformer for each of the vital buses. Attachment 2, provides a simplistic diagram of the Salem Power Distribution System. Attachment 1 provides a description for the node numbering system used by the PSE&G Load Management System (LMS) which is described in a section 2.3 and 5.

The SPTs and APTs are equipped with automatic load tap changers (LTCs) to maintain 4300 volts at the 4.16 KV vital and group buses. Also, Operation's procedure SC.OP-DD.ZZ-0023(Z) requires recording of the 4.16 KV bus voltages every 8 hours. If for any reason any of the vital buses are below 4300 volts the LTCs are placed in manual and the bus is maintained between 4300 and 4500 volts.

When either plant is in a start-up or shutdown mode, the group buses for the plant in that mode are energized by the SPTs.

2.2 Design Basis

The branch technical position PSB-1 states 11 ••• the

analysis performed to determine minimum operating voltages should typically consider maximum unit steady state and transient loads for events such as a unit trip, loss of cooling accident (LOCA), start up or shutdown; with the offsite power supply (grid) at minimum anticipated voltage ... " The basis for determining the worst case voltage profile is described below:

1.0 The minimum operating voltage on the 500 KV grid is 1.05 pu on a 500 KV base. This is based on the letter from PSE&G Distribution Systems Department (reference 4.3 ) .

2.0 The worst case alignment for the 13KV ring bus is when one unit has the group buses energized from the SPTs (during start-up or shutdown conditions) and the other is operating at full power with the group buses on the APTs. At time t=O, a Safety Injection signal is initiated, all vital equipment "BLOCK STARTS" at t=O, a reactor trip followed by. turbine trip occurs. The generator is taken off line after 30 seconds. At this time, the group buses automatically fast transfer to the SPTs. Attachment 2 shows a simplistic diagram for the configuration when unit 2 is operating from the SPTs and unit 1 is operating from the APTs. For conservatism, the unit which is operating from the APTs is at maximum load.

2. 3 Methodology

The analysis is performed using PSE&G's Load Management System (LMS) . The LMS uses PSSE software which was developed by Power Technologies Inc. (PTI) to provide voltage profiles during steady state and transient events. The command used within PSSE for this calculation is "FNSL". A description of the activity is provided in Attachment 5. This software is used in conjunction with the LMS database. The LMS database represents a model of Salem Generating Stations Units 1 and 2 electrical power distribution system from the 500 KV level to the 120 volt distribution panel level. The database provides the calculation software with all the information required to perform the analysis. For example:

Load Data

• Nameplate horsepower (HP), Brake HP, efficiency, power factor, and motor data, panel loads, heaters etc.

Branch Data

• cable types, lengths and impedances for 90 degree c.

Transformer Data

• transformer tap setting/ratios, rating, impedance based on taps and KVA rating, connection type (YY, ~-Y, etc.) Tap step for the LTCs and maximum and minimum limits the LTCs can operate.

For all of the loads, status is provided. That is, whether the load is in service or out of service for a particular mode. For a more detailed description of the software, the database, and assumptions made in developing the database, see references 4.6 and 4.7. The LMS is arranged to match the existing plant configuration:

•

•

The voltages at the group and vital buses are set to regulate at 1.035 pu of 4.16 KV.

Buses "B" & "C" are energized from SPT 12(22) and bus "A" is energized from SPT 11(21) .

Reference 4.1, is a general specification for motors and was written in 1985. Most of the 460 and 230 volt motors were purchased and installed before 1985. The NEMA standard for motors, MG 1-1978, states motors shall be capable of starting at 0.9 pu of rated motor voltage. Since there are motors which are below 0.9 pu of rated voltage during starting, and running motors which are below 0.9 pu during starting of other large motors, an evaluation has been performed to analyze the capability of these motors. This evaluation is S-C-EE-230-EEE-0790 "Motor Starting and Running During A LOCA Initiated Block Motor Start" Rev. 1. Attachment 7.10 provides the list of motors which were analyzed .

Accident Sequencing

Based on the Memorandum sent from J. Carey to M. Mortarulo on January 5,1993, the accident sequencing has been developed. This memo is provided as Attachment 6, reference 4.14. As noted in the memo, the 11(21) and 12(22) Containment Spray (CS) Pump will only start if a containment pressure hi-hi signal is present. The setpoint for this signal is 15 psi and the basis is provided in Reference 4.16. Attachment 7 provides a containment pressure profile. From this graph, the time taken to reach 15 psi is 6.25 seconds. To be conservative this calculation starts the CS Pump in five seconds.

The Service Water (SW) Pump motors operate in the following manner: If either the primary or secondary SW Pump motor is operating and a LOCA signal is detected, the other motor is not energized. However, if neither motor is energized and a LOCA signal is detected the primary SW Pump motor will start at t=O seconds, if it does not start then the secondary motor is energized at t=5 seconds. To provide conservatism, this calculation assumes two SW Pump motors are energized on the same vital bus. When a LOCA signal is detected the other two primary SW motors will be energized at t=O. Therefore, the sequence for the service water Pump motors is as follows:

• Two SW Pump motors are energized on the 4.16 KV vital "B" bus.

5.3 Results

The summary of the results of this calculation are provided in Attachments 3 and 4.

Attachment 3 and 4 Description:

Attachments 3 and 4 provide a summary table of the voltage profile study. The summary table is divided into basically 2 sections. One section, columns 1-9, is the calculated per unit bus voltage when an event happens, the other section is the worst case motor voltage under the two main events, Starting and Steady State. These two events have two colurons each. Columns 10 & 12 provide the worst case motor node number and columns 11 & 13 provide the per unit motor terminal voltage on, the bus voltage base (top #) and the motor rated voltage (bottom #) . For the MOTOR STARTING and STEADY STATE cases, columns 11 & 13 respectively, if a motor dropped below the criteria described in section 2.3.1, the next worst case motor starting or steady state voltage is provided until the criteria is met.

A detailed list for all motor rated voltages are provided in the LMS reference 4.7.

Attachment 9, provides a calculation for voltage drop from the 2A Diesel Generator to the respective 4.16 KV A bus if the generator was in service. This calculation shows the bus voltage to be 4141. 8 vol ts or . 9 9 5 6. pu. This is above the worst case steady state 0.94 pu voltage at the 4.16 KV buses calculated by this study. Therefore, this calculation also encompasses the steady state voltage criteria for vital equipment if the diesels were in service. The 2A diesel was selected because it has the longest cable run between the diesel generator and its' respective 4.16 KV bus .

6.0 CONCLUSIONS

As shown, all the Vital motors required during a probable worst case DBE pass the voltage criteria discussed, in section 2.3.1, except the following:

During the motor starting transient',the motors at nodes 16178, 26178 are below the acceptance ·criteria. These motors are 1CHE6-MTRY and 2CHE6-MTRY, # 12 and 22 Chilled Water Pumps respectively. The terminal voltages for these motors are 0.7938 and 0.7928 pu. Engineering Evaluation S-C-230-EEE-0790 "MOTOR STARTING AND RUNNING DURING A LOCA INITIATED BLOCK MOTOR START", has analyzed the capability for these motors to start at 0.748 and 0.743 pu respectively. Therefore, since the motor terminal voltage for this calculation is above the motor terminal voltage analyzed in the evaluation these motors are capable of starting .

Engineering Evaluation S-C-230-EEE-0790 Rev. l"Motor Starting and Running During a LOCA Initiated Block Start" has determined all motors analyzed in Attachment 10 (reason for analysis discussed in section 2.3.1) are capable of performing their required function during a DBE except the Auxiliary Building Supply Fans, 11, 12 21, & 22. Deficiency report DES-93-00157 has been generated to evaluate this situation and initialize any corrective action if required.

This calculation provides an analysis throughout the duration of a worst case DBE. The worst case recovery voltage has been determined to be 93.2% of 4.16KV. Because, we can take credit for the load tap changers, the worst case voltage is postulated to be the recovery voltage of 93.2%. This lowest voltage case is created by a LOCA on Unit 1 coincident with a Trip/Startup on Unit 2. After Unit 1 group buses have transferred and the transient is complete, the 4KV vital buses at Unit 1 recovery to 93.2%. There is no credible scenario that would cause the voltage to be lower than 93.2%. Therefore, the lowest bus voltage evaluated is 93.2%. At this voltage level all the vital motors shall perform as required to meet their system requirements during a worst case DBE.

Activity: FNSL FNSL,FS FNSL,OPT

Activity selector: Load flow

Function:

PSS/E Program Operation Manual

Activity FNSL applies the NeNton Raphson load flow iteration to the network modelled in the working case. Bus voltages are adjusted until the convergence tolerance is reached, the iteration limit is exceeded, or activity FNSL is terminated with the "S AB" interrupt control code.

When no suffix is specified when invoking activity FNSL, the voltages in the working case are used as the initial voltage estimate. When selected with the "FS" suffix, all voltages are initialized to unity magnitude at zero phase.

Activity FNSL provides for the following automatic adjustments:

tap ratio adjustment phase shift angle adjustment area interchange control DC converter transformer adjustment switched shunt adjustment

The program option settings at the time activity FNSL is invoked determine which of these adjustments are activated. When invoked with the suffix "OPT", the user may override any or all of the present solution adjustment option settings as well as specify a "flat start".

Interrupt control codes:

AB - terminate activity FNSL following next completed iteration NC - suppress convergence monitor NM - suppress automatic adjustment monitors DC - print DC line conditions at each load flow iteration NV - suppress incorrect plant VAR limit report

Prerequisite:

The working case must contain a validly specified load flow case with voltages that are a reasonable estimate of a solution. If the previous attempt at solution has diverged or if the quality of the voltage estimates is unknown, a "flat start" should be

·specified.

Activity ordering that the matically FNSL.

FNSL requires the determination of a sparsity preserving of network buses via activity ORDR. If FNSL detects ordering needs to be determined, activity ORDR is autoinvoked prior to commencing the iterations of activity

MINIMUM OPERATING 500-KV BUS VOLTAGE LEVEL

DATE: August 21, 1992

As per your request, Transmission Planning conducted a study to determine the minimum voltage at the Salem 500-kV bus as a result of a degraded grid condition. The study showed the lowest voltage to be above 1.05 pu. This value is higher than that concluded in our previous analysis which was transmitted in a letter from J. D. Hebson dated November 19, 1987. The increase in the 500-kV bus voltage is attributed to the addition of 1200 MVAR of shunt capacitors on the PJM 500-kV grid, and approximately 3200 MW of utility and nonutility generation in New Jersey. Table 1 shows the list of the 500-kV capacitor additions, and Table 2 shows the generation additions in New Jersey.

The analysis base cases were based on the 1996· Crown Vista study base cases. Both peak and intermediate load levels were analyzed. The Crown Vista base cases were redispatched to force out Salem No. 1 and the Hope Creek units. In the peak load. case, PJM imports were modeled at 2600 MW and New Jersey imports at 3800 MW. In the intermediate case, PJM was importing 3900 MW and New Jersey was importing 5000 MW. PSE&G was importing 1700 MW in the peak load case and 3200 MW in the intermediate load base case. Tables 3 and 4 show a summary of generation, load and interchange for the PJM pool and all member companies. Under normal operating conditions, the voltage at the 500-kV bus is maintained between 1.08 and 1.10 pu. In the analysis, the pre-contingency voitage at Salem 500-kV bus was modeled at 1.08 pu.

The most critical contingency tested was found to be the simultaneous loss of the Alburtis-Branchburg and the ElroyBranchburg 500-kV circuits and prior to any system adjustments, the remaining Salem unit was tripped. The loss of the Salem unit and the two 500-kV lines will force heavy flow over the Keeney, Hope Creek and Salem circuits, and will remove the reactive support given by the Salem unit.· The post-contingency voltage at Salem 500-kV bus was 1.056 pu .

The power is in your hands. An Ac.-M ,._ c."r 8 . ,,~ \ o.f 'J. 95-2001 REV 11/91

M. A. Mortarulo - 2 - 8/21/92

The next critical contingency was the loss of the Peach Bottom-Keeney 500-kV circuit and the trip of the remaining Salem unit prior to system adjustments. The post-contingency 500-kV voltage at Salem was 1.057 pu.

Both of the above critical contingencies exceed the MAAC and PSE&G planning criterias. Load flow transcriptions of the · study base cases and the critical contingencies are shown in Exhibits 1 thru 12.

DESIGN BASIS

2.1 The minimum allowable vital bus voltage is 94% (Ref. 6.2). The undervoltage relay dropout setpoint should be above 94% with the sufficient margin to compensate

&

a combined accuracy/repeatability error of the relays, potential transformers and testing equipment. The A dropout setpoint of 95.1 % will be considered in ~ calculation.

The minimum value of a vital bus recovery voltage during the worst transient is above 97% (Ref. 6.2, 6.3 and 6.8). ~The 97% will be considered in calculation. The undervoltage relay reset setpoint should be below the minimum bus recovery voltage.

The present technical specif ica ti on time delay setpoint is 13 seconds and allowable value is 15 seconds (Ref. 6. 5) .

All voltage and time delay setpoints will be evaluated to determine if the accuracies resulting from using relays, PTs and testing equipment are conservative.

2.2 It is required that the testing will be performed using a Digital Fluke model #BGOOA or equivalent. This model has an accuracy of 0.2% at 60 hz.

3.0 ASSUMPTIONS

3 .1 The ambient temperature range inside the associated cubicle will be between 65°F and 125°F. Reference CBD states that the ambient room temperature is between 65°F and l05°F (Ref. 6. 7) •

3.2 Since the dropout (trip setpoint) is set as a percent of pickup (reset setpoint), it is assumed that both settings drift directly proportional to each other.

3.3 A 3a (3 Sigma) accuracy can be assumed on accuracies given in the instruction manual, per telecon with manufacturer. This is based on the manufacturers' shop testing, quantity of samples, and Class lE dedication test program.

4.5 Error Evaluation

The error evaluation determines the minimum voltage which may cause the UV relay to trip. This considers the actual trip setpoint, calibration tolerances and total loop errors.

UV relay setpoint Calibration Tolerance Total error (4.4)

= 113. 000 .VAC = -0.500 VAC = -0.566 VAC

Allowable "LOOP" Trip = 111.934 VAC(94.17%)

which is greater than the minimum allowable bus voltage of 111.726 VAC (94%), therefore the UV relay setpoint of 113.0 VAC (95.1%) is acceptable.

4.5ol Allowable Value (Maximum expected Trip Calibration Error)

The Allowable value for the Trip Setpoint considers only the part of the loop tested during surveillances (Relay and Test instrument) . The calculated allowable value is the minimum voltage that ensures the relay would have functioned at or above the 94% setpoint.

Allowable value (AV) = Calculated Trip Setpoint (CSP) - Testing Inaccuracy (TI). CSP is the difference between the Analytical Limit and the Total Loop Accuracy (TLA). In this case, the limit not to be exceeded is a process limit (PL) which is the Minimum Bus Voltage ( 111.726 VAC or 94% ) and TLA is 0.566 VAC (~ection 4.4.1) o

CSP = PL + TLA = 111.726 + 0.566 = 112.292 VAC

TI = 0.319 (section 4.6.4)

AV = CSP - TI = 112.292 - 0.319 = 111. 973 (94.2%)

4.6 Reset Setpoint Calculation

4.6.1 The reset setpoint of the degraded grid relays must be less than the minimum expected recovery voltage at vi ta 1 bus. The tot a 1 error value from section 4. 4. 1 ( o. 566 VAC) should be used in the reset calculation •.

Minimum bus recovery voltage is 97\ (Refer to section 2.1).

Relay reset setpoint plus total error . s (0.97) (118.857)

S 115.291 VAC

4.6.2 The 0.9 % Deadband between trip and reset setpoints (99% dropout tap setting and internal potentiometer) is acceptable because of the following calculation:

4.6.3

4.6.4

Reset setpoint =Trip setpoint/99.1% = 113.0/(0.991) = 114.026 VAC

Actual Reset Setpoint = 114.1 VAC (96.0 %)

(Calibration Tolerance: 113.6 to 114.6 VAC )

The maximum relay reset voltage combines the relay reset setpoint including calibration tolerance and total error.

Maximum reset• 114.600 0.566

z 115.166 VAC {96.9%)

which is less than the minimum bus recovery voltage 115.291 VAC.

There fore, the undervol tage relay reset setpoint of 114.1 VAC is acceptable.

CSP is the difference between the Analytical Limit (AL) and the Total Loop Accuracy (TLA). For this case, the limit not to be exceeded is a Process Limit (PL) which is Minimum Bus Recovery Voltage (115.291 VAC or 97\) and TLA is o.566 VAC (section 4.4.1).

CSP = PL - TLA = 115.291 - 0.566 = 114.725 VAC-

If temperature is assumed to be relatively consistant between each calibration, the TI combines relay repeatability over "Allowable" DC control power range (section 4.2.2), relay repeatability at constant temperature and constant control voltage (section 4.2.3), and i Fluke accuracy (section 4.2.4): 1

METHOD FOR CALCOLATING ALLOWABLE VALUE

November 19, 1992

For the ••tpoint calculation of concern no Technical Specitication Allowable Value (Maximum Expected C&libration Errors) exiata. Allowable Values are typically calculated only far setpoint.-uaed aa inputs to th• safety analy•ia. To aaaiat you in •xplainin9 as laft/as round valu•• and ••tpoint calculation s-C•4KV-Jt>C-Ol59, a description tor th• mathcd ot calculatin9 allowable value• i• provided below:

Th• methcd that Salem has accepted tor calculatinq an allowable value is b•••d on ~he direction provided in ISA-aR67.04 Part II. oraf t 10 ot th• Recommended Practice "M•thodoloqi•• tor th• Determination o! Setpoints tor Nuclear Safety-Related Instrumentation". Our tachnical •tandard tor In•trument S•tpoint Calculations, D!-TS.ZZ-lOOl(Q) i• currently bein9 raviaad to incorporate this direction.

The recommended practice atates that •Th• allowance betwean th• allowable value and.th• trip aatpoint ahould contain that pcrtion of the instrument channal beinq teated for th• surveillance interval (monthly, quarterly, or rafualinq) and shculd account !or no more than:

tn•trument calibration uncartainti•• !or th• portion cf th• instrument channel taatad and

in•trum•nt uncertaintie• durin9 normal operation tha~ are ••••urad durin9 tastin9.

The method adopted ia to tirst •ubtract tb• Total Loop Accuracy (TLA) trcm tna Analytical limit (AL) to ensure aarqin between th• Analytical Liaic and th• ••~paint. Th• di~terance between tn• A~ and Tt.A i• a tictitiou• nuaber called th• calculated ••tpoint (CSP). Th• inatrumenc uncerta1nti•• •• di•cu••ed &»ova should· than be added to th• calculated ••tpoint (CSP) co detaraine tne allowable value.
