SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-1 8.3 ON-SITE POWER SYSTEMS 8.3.1 AC POWER SYSTEMS 8.3.1.1 Description The on-site AC power systems are divided into Class 1E and non-Class 1E systems.
Dwgs. E-1, Sh. 1, E-1, Sh. 1A, and E-1, Sh. 2 show the single line of both systems with the Class 1E system identified by a dotted line enclosure.
The on-site AC power systems consist of main generators, main step-up transformers, unit auxiliary transformers, and diesel generators. The distribution system has nominal ratings of 13.8 kV, 4.16 kV, 480V, and 208/120V.
The off-site AC power system supplies power to plant systems through two start-up transformers.
8.3.1.2 Non-Class 1E AC System The non-Class 1E portion of the on-site power systems provides AC power for non-nuclear safety related loads. A limited number of non-safety related loads are important to the power generating equipment integrity and are fed from the Class 1E distribution system through the isolation system as discussed in Section 8.1.6.1 (Regulatory Guide 1.75).
The non-Class 1E AC power system distributes power at 13.8 kV, 4.16 kV, 480V, and 208/120V voltage levels. These distribution levels are grouped into two symmetrical distribution systems emanating from the 13.8 kV buses.
All non-self-activated switchgears receive control power from the 125V DC control power sources.
The 125V DC control power sources for the non-Class 1E 13.8 kV and 4 kV switchgear breakers and 480V load center breakers are shown in Tables 8.3-17 and 8.3-18 respectively.
8.3.1.2.1 Operation The unit auxiliary transformer supplies all the non-Class 1E unit auxiliary loads except unit HVAC and Units 1 and 2 common loads, which are fed by the two startup transformers as shown on Dwgs. E-1, Sh. 1, E-1, Sh. 2, and E-4, Sh. 2.
The unit auxiliary transformer primary is connected to the main generator isolated phase bus duct tap (24 kV) while the secondary of the transformer is connected to two 13.8 kV unit auxiliary buses through a non-segregated phase bus.
During plant startup, shutdown, and post shutdown, power is supplied from the off-site power sources through the two startup transformers. In addition, capability is provided to transfer the unit auxiliary buses to the startup power source to maintain continuity of power at the unit auxiliary distribution system.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-2 In addition to the loading conditions mentioned in the above paragraph, the 13.8 kV startup buses also supply the preferred power supplies to the Class 1E load groups through their respective 13.2 kV - 4.16 kV engineered safeguard transformers as discussed in Subsection 8.3.1.3 (Dwgs. E-1, Sh. 1 and E-1, Sh. 2).
The auxiliary bus feeder breakers from the unit auxiliary transformers and the startup tie bus section are interlocked to prevent supplying power to the startup bus from the unit auxiliary transformer.
A 13.8 kV tie bus is provided for the two startup buses. A separate (not in switchgear line-up) bus tie breaker is located in the tie bus. In the event of a loss of startup power supply to the 13.8 kV startup bus, an alarm is initiated and, a time delay undervoltage relay initiates the tripping of the 13.8 kV incoming breaker and the closing of the tie breaker, resulting in a slow transfer. However, this transfer is prevented if either auxiliary 13.8 kV bus is being fed from the undervoltage tie bus section. This condition is sensed by the closure of two (2) auxiliary "b" contacts in series, one from each of the unit auxiliary bus to tie-bus circuit breakers connected to a common tie bus section.
Manual initiation of the tie breaker is also provided. However, the use of this manual control is administratively limited as an overriding means only. Under automatic operating conditions of the tie breaker, auxiliary switch "b" contacts of the startup transformer incoming breakers are also utilized as a permissive to close the tie breaker to prevent tying of the two startup transformers.
At the 4 kV ESF power distribution subsystem a three-way transfer system is provided to enable the ESF loads to connect to either of the two off-site power sources or to the standby diesel generators. Each ESF bus is normally connected to a preferred source which is one of four ES transformers connected to one of the two startup buses. During loss of one off-site power source, that is, upstream of the startup bus, the startup bus undervoltage relay will trip the feeder breaker to the ES transformer, causing a transfer at the 4 kV ESF bus. If power loss occurs between the 13 kV startup bus and the 4 kV ESF bus, a 4 kV transfer will occur. The 4 kV ESF bus transfer is initiated by the bus undervoltage relay, which trips the normal incoming breaker and subsequently closes the alternate incoming breaker. This is practically a dead bus transfer. If both off-site power sources are unavailable, the diesel generator breaker closes as soon as the diesel generator power is available.
The above transfer mechanism allows only one source breaker to be closed at any one time and to ensure this, breaker auxiliary switch contacts are used for interlocking. A manual live bus transfer is possible through a synchronizing device in which case an alternate source breaker is first closed and is followed by an automatic tripping of the preferred supply breaker. In this case the duration of the tie is merely a few cycles. Furthermore, the diesel generator can be tied with any one of the two off-site sources for an indefinite time under test condition but this does not in any way cause the two off site power systems to be tied together.
The plant security load center is double ended, each end being supplied from one of the 13 kV start-up buses through a stepdown transformer and is provided with a normally open tie breaker.
Each bus is supplied from its own start-up source. Should one source be lost the undervoltage relay at the transformer secondary trips the bus incoming breaker. The bus undervoltage relay then initiates closure of the tie breaker provided the incoming breaker has successfully tripped.
Upon return of the failed source the incoming breaker will not automatically close and can only be manually closed after the tie breaker has been tripped.
In all of the foregoing tie or transfer systems, there is no way that the two off-site power systems can be tied together at the on-site buses assuming loss of one off-site source.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-3 The 13.8 kV switchgear provide power for large auxiliary loads and 480V load centers. The 13.8 kV switchgear feed double-ended 480V load centers. A manual tie breaker is provided for each set of load centers to intertie the two load centers in the event of failure of one load center transformer. Load centers generally supply power to 480V loads larger than 100 hp and power for their respective motor control centers. The motor control centers supply 480V loads smaller than 100 hp while 480V, 480/277V, 208/120V panels provide miscellaneous loads such as unit heaters, space heaters, lighting systems, etc.

E-1, Sh. 1 and E-1, Sh. 2.
The Class 1E AC system distributes power at 4.16 kV, 480V, and 208/120V to the safety related loads. The safety related loads are divided into four load groups per generating unit and are tabulated in Table 8.3-1. Each load group has its own distribution system and power supplies.
The 4.16 kV bus of each Class 1E load group channel is provided with connections to two off-site power sources designated as preferred and alternate power supplies. Diesel generators are provided as a standby power supply in the event of total loss of the preferred and alternate power supplies. Standby power supply is discussed in Subsection 8.3.1.4.
Preferred and alternate power supplies up to the 4.16 kV buses of the Class 1E power system are considered as non-Class 1E.
All non self-activated switchgears receive control power from the 125V DC control power sources.
The 125V DC control power sources for the Class 1E 4.16 kV switchgear breakers and 480V load center breakers are shown in Tables 8.3-19 and 8.3-20 respectively.
In order to achieve adequate separation between channelized load group and divisionalized load group, two 125V DC control power supplies are provided for each 4.16 kV switchgear (refer to Table 8.3-19).
8.3.1.3.1 Power Supply Feeders Each Class 1E 4.16 kV switchgear of a load group channel is provided with a preferred and an alternate (off-site) power supply feeder and one standby diesel generator feeder. Each bus is normally energized by the preferred power supply. If the preferred power source is not available at the 4.16 kV bus, automatic transfer is made to the alternate power source as described in Subsection 8.3.1.3.6. If both preferred and alternate power feeders become de-energized, the safety-related loads on each bus are picked up automatically by the standby diesel generator assigned to that bus as described in Subsection 8.3.1.4.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-7 8.3.1.3.2 Power Feeder Cables Power feeder cables for the 4.16 kV system are aluminum or copper conductors, and are rated 5 kV, 90°C conductor temperature with high temperature insulation. The cables are provided with an overall flame resistant jacket covering. For the main plant's 480V system, cables of size
- 4/0 AWG and larger are aluminum or copper conductor; cables less than #4/0 AWG are copper conductor. In the Diesel Generator E building and the ties to the Diesel Generator A, B, C or D transfer points, all cables are copper conductor. Both types of cables are rated 600V, 90°C conductor temperature with ethylene-propylene insulation with a flame-resistant hypalon jacket covering. The conductors are sized to carry the maximum available short circuit current for the time required for the circuit breaker to clear the fault. All Class 1E cables have been designed for operation as discussed in Section 3.11.
The 4.16 kV switchgear and D.C. load centers are equipped with aluminum buses and silver-plated bolted connections. The D.C. Control centers are equipped with copper buses and silver-plated bolted connections. The 480V load centers and motor control centers are equipped with copper or aluminum busses and the bolted connections are silver-plated or alston 70 (respectively). All circuit breaker terminals are copper. For power cable terminations, Burndy compression aluminum terminals (HYLUG) are used. These terminals are of seamless tubular construction, tin-plated to resist corrosion, and factory filled with oxide inhibiting compound penetrox A. Compression adapters MAC ADAPT MPT series or equivalent are used for equipment/vendor supplied components having mechanical lugs which cannot be converted to accept a Burndy compression lug due to physical or practical limitations. A non-oxidizing lubricant such as D50H47 or equivalent will be applied on all contact surfaces at bolted joints to avoid damaging the silver-plated contact surfaces.
8.3.1.3.3 Bus Arrangements The Class 1E AC system is divided into four load group channels per unit (load group Channels A, B, C, and D). Power supplies for each load group are discussed in Subsection 8.3.1.3.1. All Class 1E AC loads are divided among the four load groups so that any combination of three out of four load groups has the capability of supplying the minimum required safety loads.
The distribution system of each load group consists of one 4.16 kV bus, one 480V load center, four or five motor control centers, and several low voltage distribution panels. The bus arrangements are shown on Dwgs. E-1, Sh. 1, E5, Sh. 1, E-5, Sh. 2, E-8, Sh. 4, E-8, Sh. 8, Figure 8.3-9-1 (U1) and Figure 8.3-9-2 (U2).
8.3.1.3.4 Loads Supplied from Each Bus Table 8.3-1 provides a listing of all the loads supplied from each Class 1E bus.
8.3.1.3.5 Class 1E Isolated Swing Bus Two redundant 480V swing buses are provided for each unit for the RHR injection valve motor operators, recirculation loop bypass valve motor operators, and recirculation discharge valve motor operators. The single line of the swing bus is shown on Figure 8.3-9-1 (U1) and Figure 8.3-9-2 (U2).
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-8 A Class 1E 480V load center of one load group channel supplies the preferred power to the swing bus through the electrical isolation of a motor-generator (M-G) set. The alternate power is supplied directly from another redundant Class 1E 480V load center. The M-G set is used for electrically isolating two redundant load groups. Faults at the swing bus cannot be propagated onto more than one load group.
The swing buses are Class 1E motor control center constructions. An automatic transfer switch is provided for transferring the swing bus from the preferred to the alternate power source upon reduction or loss of voltage at the swing bus. If the undervoltage is caused by a fault at the swing bus, the transfer will be prevented even if the alternate power is available. The swing bus will be retransferred back to preferred power when the voltage is restored within acceptable limits.
The swing bus and transfer switch are designed so that for a loss of off-site power and any single failure, the minimum required ECCS flow to meet 10CFR50 Appendix K criteria is always available.
The following is a common mode-common cause failure analysis (CMCCFA) for the automatic transfer switches:
Figure 8.3-13 depicts a simplified single line diagram for the swing bus system to facilitate the analysis. Table 8.3-24 and Table 8.3-26 provides a step-by-step CMCCFA of the auto transfer switch by postulating the various major common causative factors (events).
Normal conservatism in design and manufacturing margins, mandatory requirements of QA/QC procedures, Initial Test Program, Preoperational Tests, applicable administrative procedures and maintenance programs as well as operator actions contribute to minimize the susceptibility of the auto transfer switch to the various common causative factors as analyzed in Table 8.3-24 and Table 8.3-26.
This analysis demonstrates that the transfer switch, as a component of the swing bus system design, will not degrade the independence and separation between the redundant Class 1E channels (load center channels A and C or B and D).
The test program (Section 14.2 and Technical Specification) for the 480V swing bus system (Figure 8.3-13) consists of:
a)
Periodic inspection of wiring, insulation, and connections, etc., to assess the continuity of the components and system.
b)
Periodic testing to verify the operability and functional performance of individual components in the system.
c)
Periodic testing of operational sequence and operability of the system as a whole.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-9 8.3.1.3.6 Manual and Automatic Interconnections Between Buses, Buses and Loads, and Buses and Supplies No provision exists for automatically or manually connecting one Class 1E load group to the redundant Class 1E load group or for automatically transferring loads between load groups except the swing buses as discussed in Subsection 8.3.1.3.5. For each load group, one 4.16 kV feeder circuit breaker is provided for the normal incoming preferred power source, and another 4.16 kV feeder circuit breaker is connected to the alternate power source (see Subsection 8.3.1.3.1). The normal preferred power source to each bus is electrically interlocked with the alternate power source such that the bus can be connected to a single power source at any one time. In the event of loss of preferred power to the load group, undervoltage relays (less than or equal to 20 percent voltage) on the 4.16 kV switchgear will initiate an automatic transfer to the alternate power source if available. In the event of losing both preferred and alternate power supplies, the load group will be powered from the standby diesel generator.
See response to FSAR Question 40.6 for a description of the degraded grid voltage protection scheme. Restoration of power from standby power to the preferred source of offsite power is manually initiated in the control room on panel 0C653. When the standby power source is in synchronism with the offsite power source, the preferred offsite source incoming breaker is closed.
Upon closing of this preferred source breaker, the standby source breaker will automatically trip.
This tripping is initiated by the preferred offsite source breaker auxiliary switch contact interlock.
A similar procedure is used to restore power from standby to the alternate offsite power source.
8.3.1.3.7 Interconnections Between Safety Related and Non-Safety-Related Buses, Non-safety Related Loads, and Safety-Related Buses Discussion of interconnections between safety related and non-safety related buses, non-safety related loads, and safety related buses is presented in Subsections 3.12.2 and 8.1.6.1.
8.3.1.3.8 Redundant Bus Separation The engineered safety features switchgear, load centers, and motor control centers for the redundant Class 1E load groups are located in separate Seismic Category I rooms in the reactor building to ensure electrical and physical separation. Electrical equipment separation is discussed in Subsection 3.12.2 and Subsection 8.1.6.1. Equipment layout drawings can be found in Section 1.2.

The timing sequence for the ESF loads is shown in Table 8.3-1, except for the RHR and core spray pumps which is shown in Table 8.3-1b.
- Diesel Generator E
- Diesel Generator E
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-11 In the event of loss of preferred and alternate off-site power supplies, the Class 1E 4.16 kV buses will shed all loads except the 480V load centers and connect the standby Diesel Generator to the Class 1E bus. The load sequence timing is shown on Table 8.3-1. If Diesel Generator E is aligned and the preferred and alternate offsite power supplies are lost the 480V motor control center supplying the diesel auxiliaries automatically transfers to the Diesel Generator E 4.16 kV Bus when Diesel Generator E is running. However, if a slow bus transfer (bus voltage on transfer is less than 20%) at the Class 1E 4.16 kV bus is initiated to the alternate off-site power as a result of a loss of preferred off-site power, all loads are shed except the 480V load centers. Then the required ESF loads are sequenced onto the Class 1E 4.16 kV Buses. The timing sequence for ESF loads is shown in Table 8.3-1, except for the RHR and core spray pumps which is shown in Table 8.3-1b.
Tables 8.3-1 and 8.3-1b show the anticipated starting time of all ESF loads. Both Unit 1 and Unit 2 buses for a given diesel generator are normally supplied by the same off-site power supply. An individual timing unit is provided for each of the ESF loads with automatic start function. Failure to start one load will not affect the starting initiation of other loads.
The loading sequence for a simultaneous LOCA in one unit and a false LOCA in the other unit is shown in Table 8.3-1b. A false LOCA signal as used in this section refers to a non-mechanistic failure resulting in a LOCA signal in one reactor unit when a LOCA has not occurred in that unit.
The load starting transient on the diesel generators is reduced if the Unit 1, and Unit 2 load sequences do not start simultaneously.
If off-site power is available, the LOCA signal in one unit and false LOCA signal in the other will shed 2 RHR motors and 2 core spray motors of each unit and sequentially start 2 RHR and 2 core spray motors as shown in Table 8.3-1b. This is done in order not to exceed the utilization voltage limitation of connected equipment and to provide at least the minimum core cooling requirements of both units. Under the modified core cooling arrangement, 2 RHR pumps (one in each loop) and 2 core spray pumps (both in the same loop) will satisfy the minimum cooling requirements of each unit. Approximately ten minutes after the above event the operator will be able to determine which is the false-LOCA unit and shutdown non-essential loads in the non-LOCA unit. In case off-site power is not available, the loading is the same as discussed above, but the sequencing is slightly altered as shown in Table 8.3-1b.
All conditions discussed above support the safety function time limits depicted on Table 6.3-1.
8.3.1.3.11 Safety Related Equipment Identification Subsection 8.3.1.11.3 provides information regarding the physical identification of Class 1E equipment.
8.3.1.3.12 Instrumentation and Control Systems for the Applicable Power Systems with the Assigned Power Supply Identified The DC power supplies for the control of the redundant Class 1E equipment are physically and electrically separate and independent. Refer to Subsection 8.3.2 for a detailed discussion of the DC system.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-12 8.3.1.3.13 Electric Circuit Protection Systems Protective relay schemes and direct-acting trip devices on primary and backup circuit breakers are provided throughout the on-site power system in order to:
a)
Isolate faulted equipment and/or circuits from unfaulted equipment and/or circuits b)
Prevent damage to equipment c)
Protect personnel d)
Minimize system disturbances e)
Maintain continuity of the power supply Major types of protection measures employed include the following:
a)
Bus Differential Relaying A bus differential relay is provided for each Class 1E 4.16 kV bus. This relay provides high speed disconnecting of bus supply breakers to prevent propagation of internal bus fault to another bus.
b)
Overcurrent Relaying Each Class 1E 4.16 kV bus feeder circuit breaker is equipped with three extremely inverse-time overcurrent relays to sense and to protect the bus from an overcurrent condition.
The standby diesel generator feeder circuit breaker to the 4.16 kV bus is equipped with three voltage restrained overcurrent relays for feeder circuit protection. One diesel generator inverse time ground fault relay provides ground fault indication for the diesel generator including the 5 kV cables from the diesel generator to the 4.16 kV bus.
Each 4.16 kV motor feeder circuit breaker has three overcurrent relays, each with one long time and one instantaneous element for overload, locked rotor, and short-circuit protection.
Each breaker is also equipped with an instantaneous ground current relay.
Each Class 1E 4.16 kV supply circuit breaker to a 480V load center transformer is protected by three overcurrent relays with long-time and instantaneous elements. An instantaneous overcurrent ground sensor relay provides sensitive ground fault indication.
c)
Under/Overvoltage Relaying Each 4.16 kV Class 1E bus is equipped with undervoltage relays to detect low voltage and initiate a transfer to the alternate source and provide undervoltage annunciation. Each 4 kV bus is provided with degraded grid voltage protection. Each 480V Class 1E load center bus is equipped with under/overvoltage relays for annunciation. The Diesel Generator E 480V Class 1E motor control center is equipped with undervoltage relays for annunciation.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-13 d)
Diesel Generator Differential Relaying Each diesel generator is equipped with differential relaying protection. This circuitry provides high speed disconnection to prevent severe damage in case of diesel generator internal faults.
e) 480V Load Center Protection Each load center circuit breaker is equipped with integral, solid-state, dual magnetic, adjustable, direct-action trip devices providing inverse-time overcurrent protection. Motor feeders are equipped with long-time overcurrent and instantaneous short-circuit protection.
f) 480V Motor Control Center Protection Molded-case circuit breakers provide inverse-time overcurrent and/or instantaneous short circuit protection for all connected loads. For motor circuits, the molded-case circuit breakers are equipped with an adjustable instantaneous magnetic trip function only.
Motor thermal overload protection is provided by the heater element trip unit in each phase of the motor feeder circuit. The molded-case breakers for non-motor feeder circuits provide thermal inverse-time overcurrent protection and instantaneous short circuit protection. The thermal overload trip units for safety related motor-operated valves are normally bypassed except during maintenance tests.
The circuit protection system is designed so that fault isolation is secured with a minimum circuit interruption. The combination of devices and settings applied affords the selectivity necessary to isolate a faulted area quickly with a minimum of disturbance to the rest of the system. The protective devices are preoperationally tested in accordance with the requirements of Chapter 14.
After the plant is in operation, periodic tests will be performed to verify the protective device calibration, setpoints, and correct operation in accordance with the requirements of Chapter 16.
8.3.1.3.14 Testing of the AC System During Power Operation All Class 1E circuit breakers and motor starters, except for the electric equipment associated with Class 1E loads identified in Subsection 8.3.1.3.15, are testable during reactor operation. During periodic Class 1E system tests, subsystems of the ESF system such as safety injection, containment spray, and containment isolation are actuated, thereby causing appropriate circuit breaker or contactor operation. The 4.16 kV and 480V load center circuit breakers and control circuits can also be tested independently while individual equipment is shut down. The load center circuit breakers can be placed in the test position and exercised without operation of the related equipment.
8.3.1.3.15 Class 1E Loads Not Testable During Power Operations A.
Feedwater Line Isolation Valves The feedwater line isolation valves (HV-F032 A/B) are of the motor operated check valve type and are not testable with the feedwater flow present. Motor operation is not required for isolation. Only the outermost isolation valve is Class 1E powered and would be motor operated for long-term isolation after isolation of the feedwater line.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-14 Conformance with Regulatory Guide 1.22 Section D.4:
- 1.
The feedwater isolation is not designed for isolation with feedwater flow present as the loss of flow would adversely affect operability of the plant.
- 2.
Motor operation is not required for isolation.
- 3.
The motor operator of the outermost isolation valve is fully testable during shutdown.
B.
Main Steam Isolation Valves The main steam isolation valves can be tested individually to the 90% open position at full power with the slow acting test solenoid valve. A fully closed test using the two fast acting main solenoids would require a reduction in reactor power.
Conformance with Regulatory Guide 1.22: See Subsections 7.3.2a.2.2.1.2 and 5.4.5.4.
C.
ADS System - Safety/Relief Valves The active components of the ADS system except the safety/relief valves and their associated solenoid valves are designed so they may be tested during plant power operation. The relief valve and associated solenoid are not tested during reactor power operation.
Conformance with Regulatory Guide 1.22:
- 1.
The safety/relief valves are not tested during power operation because of resulting adverse affect on plant operation.
- 2.
Because of low failure rates of valve actuation, the probability of failure is acceptably low without testing.
- 3.
The safety/relief valves and associated solenoid valves can be tested during startup following shutdown.
D.
Recirculation Loop Isolation Valves The recirculation pump isolation valves are not tested during reactor power operations.
Conformance with Regulatory Guide 1.22 Section D.4:
- 1.
Operation of a recirculation loop isolation valve would result in a reduction of circulation which would adversely affect the safety and operability of the plant.
- 2.
The probability of failure is acceptably low without testing the valve motor during operation.
- 3.
The valve and motor are fully testable during reactor shutdown.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-15 8.3.1.4 Standby Power Supply The standby power supply for each safety related load group consists of one diesel generator complete with its accessories and fuel storage and transfer systems. An additional diesel generator (diesel generator E) complete with its accessories and fuel storage and transfer system can be substituted for any one of the 4 normally aligned diesel generators (A, B, C, or D) and aligned to the safety-related load group. Each diesel generator (A, B, C, or D) is rated 4000 kW at 0.8 pf for continuous operation and 4700 kW for 2000 hr operation. The additional diesel generator (E) is rated 5000 kW at 0.8 pf for continuous operation and 5500 kW for 2000 hr operation. The ratings for each diesel generator are calculated in accordance with the recommendation of Regulatory Guide 1.9 (discussed in Subsection 8.1.6.1). The diesel-generators can operate at loads of from 50 to 100 percent for unlimited periods without harm. Any diesel generator continuously operated at loads of less than 50 percent will be loaded in accordance with the manufacturers recommendations to remove any built up combustion products. Question 040.82 and the response contain further information. Any diesel operating at loads of less than 50 percent for less than six hours will be loaded in accordance with manufacturers recommendations to remove any built up combustion products. Question 040.82 and the response contain further information. Such operation will enhance engine performance and reliability.
The diesel generators are shared by the two units. There are a total of five diesel generators.
Diesel Generators A, B, C and D are normally assigned to the safety-related load groups. Diesel Generator E is capable of being substituted for any of the Diesel Generators A, B, C or D without violating the independence of the redundant safety-related load groups. Only four diesel generators can be aligned to the safety-related load groups. When a diesel generator is aligned, it is connected to the 4.16 kV bus of the assigned load group per unit. The capacity of the aligned diesel generators (assuming one of the aligned diesels fails) is sufficient to operate the engineered safety features loads of one unit and those systems required for concurrent safe shutdown of the second unit.
There are no provisions for parallel operation of the aligned diesel generator of one load group with the aligned diesel generator of the redundant load group. The diesel generator circuit breaker and the off-site power incoming circuit breakers are interlocked to prevent feedback into the off-site power system. These interlocks are bypassed during load testing of the aligned diesel generator; however, only one unit is tested at any one time. During the test period, the diesel generator under test is manually synchronized to the preferred off-site power system. Upon receipt of a LOCA signal under the test condition, the diesel generator breaker is tripped but the aligned diesel generator continues to run. When not aligned, Diesel Generator E can be tested through a 13.8-4.16 kV test facility transformer which permits Diesel Generator E to be synchronized to the offsite power system. Cooling water under these conditions is provided by LOOP A and/or B of the Emergency Service Water System. During the test, Diesel Generator E is under local manual control. A LOCA or a LOOP signal during the test, trips the 4.16 kV output breaker and closes the ESW LOOP A and B supply and return valves in the Diesel Generator E building.
Control power for Diesel Generator E is from a single 125V DC system in the Diesel Generator E building. When Diesel Generator E is aligned, loss of DC power is indicated on the BIS panel and group trouble alarm on panel 0C653 in the location of the diesel generator for which Diesel Generator E has been substituted.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-16 The diesel generators are physically and electrically isolated from each other. Physical separation for fire and missile protection is provided between Diesel Generators A, B, C and D by separate rooms within a Seismic Category I structure. Diesel Generator E is protected in a separate Seismic Category I structure. Power and control cable for each of the diesel generators and associated switchgear are routed in separate raceways. Physical electrical equipment layout of the diesel generator rooms is shown on Dwgs. M-260, Sh. 1, M-261, Sh. 1, and M-5200, Sh. 1.
Auxiliaries required for starting and continuous operation of Diesel Generators A, B, C and D are fed by the Class 1E power load group associated with that diesel generator. Diesel Generator E has a separate Class 1E power system in the Diesel Generator E building for starting and continuous operation.
Control power for Diesel Generators A, B, C or D is provided by its corresponding 125V DC systems from both Unit 1 and Unit 2. These two power feeders are not redundant but have been provided for ease of maintenance. Indication of which unit is supplying the DC control power is not provided in the control room. Manual switches are installed at the local panel to select the preferred power feeder. Since these diesel generators are shared by both units, either source of DC control power is adequate. Loss of DC power to the Diesel Generators A, B, C or D when aligned is indicated on the BIS panels as a group trouble alarm on panel 0C653 in the main control room.
Each diesel generator is provided with a local engine control panel, a generator-exciter control panel, a local 4.16 kV distribution panel, and a 480V motor control center in the diesel generator room. In addition, Diesel Generator E has a 125V DC motor control center.
a)
Local Engine Control Panel - consists of a local annunciator, engine control devices, gauges, and control for diesel generator auxiliary equipment such as fuel oil transfer pump, standby jacket water pump, etc.
The diesel generator control system is designed in such a manner that some control devices are mounted in the free-standing control panel separate from the engine, while others are mounted directly on the engine, as required for reliable service. All devices that are essential to the start-up or power output of the diesel-generator set have been seismically qualified by analysis or test to acceleration levels consistent with their mounting location.
b)
Generator-Exciter Control Panel - consists of generator excitation control equipment, generator protective relays and devices, etc.
c) 4.16 kV Distribution Panel - In the Diesel Generator A, B, C and D rooms, the panel provides connections for the aligned diesel generator feeders to Unit 1 and 2. Also houses potential transformers and current transformer, etc.
d) 480V Motor Control Center - provides power to all 480V auxiliary equipment related with that diesel generator. The MCC in Diesel Generator A, B, C or D room is equipped with an automatic transfer switch for connection to either Unit 1 or 2 480V Class 1E load center.
These two load centers belong to the same load group channel as the diesel generator.
The Diesel Generator E MCC is connected to an automatic transfer switch which can supply power from either offsite power source. In the event that both sources are lost and Diesel Generator E is operating, the MCC is transferred to the Diesel Generator E 4.16 kV bus and powered from a 4.16 kV-480V Class 1E transformer.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-17 e) 125V DC motor control center - provides power to the Diesel Generator E emergency service water motor operated valves.
Physical separation of standby power system is discussed in Section 3.12.
Diesel Generator Transfer Scheme Diesel Generator E is capable of being substituted for any one of Diesel Generators A, B, C or D.
Substitution is accomplished by manually transferring control of Diesel Generator E to the control room using cabling from the substituted diesel generator and manually transferring Diesel Generator E 4.16 kV leads to the high voltage compartment of the substituted diesel generator.
All the cables transferred to Diesel Generator E are routed through two normally open switching points; one point located in each Diesel Generator A, B, C and D rooms and a corresponding switching point for Diesel Generators A, B, C and D in the Diesel Generator E building. This arrangement maintains the independency of the safety related load groups.
Diesel Generator E is connected directly to a Class 1E 4.16 kV bus in the Diesel Generator E building. Four cubicles on the 4.16 kV bus serve as the switching points for the Diesel Generator E 4.16 kV leads to the 4.16 kV buses located in each Diesel Generator A, B, C and D rooms. These buses are the corresponding switching points in the Diesel Generator A, B, C and D rooms.
The transfer of the controls of Diesel Generator E to the main control room is achieved by manually switching the control room instrumentation and control cables from the substituted diesel generator to the Diesel Generator E. Transfer panels in each Diesel Generator A, B, C or D room are used to perform the switching. Duplicate transfer panels located in the Diesel Generator E building are also used to perform the switching. This provides two isolation points for each transferred cable.
8.3.1.4.1 Automatic Starting Initiating Circuits The four (4) aligned diesel generators are automatically started by any of the following conditions:
a)
Total loss of power to the 4.16 kV Class 1E bus of either unit to which the diesel generator is connected.
b)
Safety injection signal - low water level in the reactor, high drywell pressure, or manual actuation.
Two control/starting circuits are provided for each diesel generator. Each circuit is supplied via separate circuit breaker from the same 125-volt battery. Failure of one circuit that does not affect the other would not prevent the respective diesel generator from starting.
The diesel generators are ready to accept loads within 10 seconds after the initiation of the start circuit.
8.3.1.4.2 Diesel Starting Mechanism and System The diesel generator starting air system is described in Subsection 9.5.6. To ensure fast and reliable starting, each diesel engine is provided with immersion heaters in the engine jacket water and the lube oil system to maintain the engine coolant and lube oil temperature at an operable level. For Diesel Generators A, B, C and D, the electric jacket water immersion heater and the
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-18 water circulating pump are interlocked for simultaneous operation when the jacket water temperature drops below the preset temperature. The electric lube oil immersion heater and the prelube circulating pump are interlocked for simultaneous operation when the engine is below 280 rpm. For Diesel Generator E, both the jacket water circulating pump and the prelube circulating pump start when the engine is below 280 rpm. The electric jacket water immersion heater and lube oil immersion heater are controlled by temperature switches. The heaters are interlocked with the corresponding circulating pump to prevent the heater from operating unless the pump is running. Refer to Subsections 9.5.5 and 9.5.7 for further description.
8.3.1.4.3 Alarm and Tripping Device The protective and alarm logic diagrams for the diesel generator and its associated breakers are shown on Dwgs. E-31, Sh. 8 and E-31, Sh. 9.
While supplying loads following an automatic start, each diesel engine and related generator circuit breaker are tripped by protective devices under the following conditions only:
a)
Engine overspeed b)
Lube oil low pressure c)
Generator differential To prevent spurious tripping of the diesel generator due to malfunction of the engine lube oil low pressure trip device, four independent sensors are provided and connected in a coincidence one-out-of-two taken twice tripping logic. An individual tripping alarm is provided by the annunciator at each local control panel.
The starting circuit is also equipped with a "fail to start" relay operator that interrupts the starting of the diesel generator if a predetermined speed during test mode of operation is not reached within a limited time following a start initiation.
In addition to the above-listed trips, each generator circuit breaker is tripped by the following protective relays to disconnect the aligned generator from a faulty bus (the diesel generator continues to run):
a)
Voltage restrained overcurrent b) 4 kV bus differential Following a manual start of an aligned diesel generator, the diesel generator is in the test mode and ready for a load test. When so operated, in addition to the above-listed trips, the diesel engine and related generator circuit breaker are automatically tripped during test mode by the following protective devices:

Diesel generator not in automatic mode When Diesel Generator E is not aligned, it can be tested through a test facility. Diesel Generators A, B, C or D do not have the capability of being tested when not aligned. When operating through the test facility, Diesel Generator E has the same automatic trips and individual alarms as an aligned diesel generator. However, the alarm conditions are only provided at the local control panel. High and low priority alarms are not annunciated in the main control room.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-22 8.3.1.4.4 Breaker Interlocks Interlocks have been provided in the closing and tripping of the 4.16 kV Class 1E circuit breakers to protect against the following conditions:
a)
Automatic energizing of electric devices or loads during maintenance b)
Automatic closing of the diesel generator breaker to any energized or faulted bus c)
Connecting two sources out of synchronism 8.3.1.4.5 Control Permissive A single key-operated switch at the local control panel is provided for each diesel generator to block automatic start signals when the aligned diesel is out of service for maintenance. An annunciator alarm in the main control room and an indication at the bypass-indication-system panel indicate when the switch is not in automatic position.
A pushbutton in the control room and a local pushbutton at the local control panel in the aligned diesel generator room/building are provided to allow manual start of the diesel when all protective systems are permissive. During periodic diesel generator tests of an aligned diesel generator, permissives and interlocks are designed to permit manual synchronizing and loading of the diesel generator with either off-site power source.
A key-operated switch at the local control panel is provided for each diesel generator to regain speed and voltage control of the aligned diesel generator following a loss of and subsequent restoration of offsite power. This permits the aligned diesel generator to be synchronized to the offsite power source, while maintaining the diesel generator in the emergency mode of operation.
An annunciator alarm in the main control room indicates when the switch is not in the normal position.
A transfer scheme is provided as described in Section 8.3.1.4. Proper alignment of the manual control switches on the transfer panels and the position of the 4.16 kV transfer switchgear is required to permit Diesel Generator E to be substituted for Diesel Generator A, B, C or D. Local indication and control room indication of the transfer scheme is provided to assure proper alignment.
The sequence for transferring the controls of Diesel Generator A, B, C or D to Diesel Generator E begins with the diesel generator being removed from service and ends with the diesel generator being placed in-service or aligned. The sequence begins by placing the "Enable-Disable" switch in the "Disable" position on the transfer panel of the diesel generator being taken out of service. This action removes all auto start signals from the diesel generator and gives an indication that the transfer scheme is misaligned. The remaining switching operation at the transfer panel and the repositioning of the 4.16 kV breaker and ESW valves occurs at the diesel generator being taken out of service. Next, the switching at the transfer panel and repositioning of the 4.16 kV breaker and ESW valves occurs at the diesel generator being put in-service or aligned. Finally, the sequence is completed by placing the "Enable-Disable" switch in the "Enable" position on the transfer panel of the diesel generator being put in service or aligned. This action removes the indication of a transfer scheme misalignment.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-23 8.3.1.4.6 Loading Circuits Upon automatic starting of an aligned diesel (emergency mode), connection of the diesel generator to the 4.16 kV bus is not made unless both off-site power sources are lost. As the generator reaches the predetermined voltage and frequency levels, control relays provide a permissive signal for the closing of the respective diesel generator breaker to the corresponding 4.16 kV bus. The diesel generator circuit breaker is closed within 10 seconds after the receipt of the starting signal.
The required safety related loads are connected in sequential order to the Class 1E buses as shown in Table 8.3-1. This prevents diesel generator instability and ensures voltage recovery thereby minimizing motor accelerating time. A fast-responding exciter and voltage regulator ensures voltage recovery of the diesel generator after each load step.
With one diesel generator unavailable, the remaining three in-service diesel generators have the capacity and capability to supply the required engineered safeguard features loads in one unit; the equipment needed to safely shutdown the second unit; and any more engineered safeguard features loads manually switched onto the diesel generators as illustrated in Tables 8.3-2 through Table 8.3-5a. These tables represent a worst case loading based on mechanical and electrical equipment availability. The plant operators may choose to run different equipment than that specified in the tables after 10 minutes. However, by procedure the loading of each diesel generator will be maintained below 4000 kW long term.
8.3.1.4.7 Testing Preoperational Test Diesel Generators A, B, C and D were tested at the site prior to reactor fuel loading in accordance with requirements of Chapter 14. Diesel Generator E was tested at the site prior to declaring it operational in accordance with requirements of Chapter 14.
Periodic Testing After being placed in service, the standby power system is tested periodically to demonstrate continued ability to perform its intended function, in accordance with the requirements of Chapter 16.
8.3.1.4.8 Fuel Oil Storage and Transfer System The diesel generator fuel oil system is described in Subsection 9.5.4.
8.3.1.4.9 Diesel Generator Cooling and Heating The diesel generator cooling system is described in Subsection 9.5.5.
8.3.1.4.10 Instrumentation and Control Systems for Standby Power Supply The instrumentation and control circuit of Diesel Generators A through D is provided with a manual selector switch for connection to either Unit 1 or 2 125V DC power supply. These two power supplies belong to the same load group channel to which the diesel generator is connected. Diesel Generator E has a separate 125V DC power supply in the Diesel Generator E building.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-24 Since there are five diesel generators of which only four can be aligned for emergency operation at one time, the control room hardware can only operate the aligned diesel generators. The control room hardware performs the following operations:

f)
To evaluate the seismic effects on the safe shutdown capability some tests have been performed, but most evaluations were achieved by analysis. Both CES and vendor furnished equipment, which are essential to the power output capability of the generator, have been seismically evaluated and determined adequate to meet the specified response spectra with no loss of functional or structural integrity. The documentation for the seismic analyses and tests is contained in SQRT binders maintained by Susquehanna Records Management System.
8.3.1.4.11.3 Performance In Service Environment Actual performance requirements and service conditions are achievable in the field installation only. Simulation of performance is attained through computer techniques which comparatively analyze motor starting data taken during factory testing with motor load starting characteristics predicted for the essential pumps-motors to be started at the jobsite. Simulation of service environments, such as the predicted diesel generator room ambient temperature, would require an environmental chamber large enough to store the entire engine-generator set. In order to ascertain the ability of this equipment to perform in the predicted environment, operating experience and design experience are used. The varied types of engines designed, the varied installation applications, and the resultant experience gained have determined the capabilities of this equipment to perform under different service conditions. This experience is augmented by previous and ongoing R&D testing of a similar CES Type KSV engine where specific data may be needed relative to particular performance requirements. However, much of this data is proprietary.
As a result of this experience and testing, it is concluded the service conditions described in Section 3.11 can be accommodated while fulfilling the performance requirements. For example, installation elevations of up to 1500 feet are accommodated without any derating or design modification. The 676 feet elevation for the Susquehanna SES diesel-generator sets falls well within this range. To accommodate variance in combustion air temperature, coolers/heaters are supplied which either add heat to or take heat from combustion air as needed to provide the necessary manifold air temperature. The range of -19°F to +105°F air temperature is therefore accommodated.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-27 In addition, all emergency service water heat exchangers are designed with fouling factors incorporated permitting the buildup of specified amounts of dirt or sludge while maintaining the necessary heat transfer characteristics under the most adverse load and cooling water temperature conditions. Particles or minerals in the service water are therefore accommodated in heat exchanger design.
Seismic effects are taken into account analytically and/or by test for all essential components and systems of the diesel-generator sets.
8.3.1.4.11.4 Periodic Test Periodic exercising of the diesel generator sets shows availability and reliability. The diesel generator equipment will undergo periodic testing in accordance with the Technical Specifications.
This testing is implemented as part of the surveillance test program.
Data taken during those tests will be compared to previous test data taken during similar load conditions. This will aid in the development of trends that may indicate equipment degradation and the prediction of maintenance intervals. Equipment maintenance histories will be kept for the diesel generators and completed surveillance testing and preventive maintenance will be documented in the history.
8.3.1.4.12 Control and Alarm Logic A transfer switching scheme is provided for the diesel generators to permit Diesel Generator E to be substituted for Diesel Generator A, B, C or D. The transfer scheme transfers the control and alarm logic so that the logic is only functional for the diesel generators which are aligned for operation. The following analysis is only applicable to the diesel generators which are aligned.
The control and alarm logic for the diesel generators is shown on Dwg. E-31, Sh. 9. Conditions which render the diesel generator incapable of responding to an automatic emergency start are shown on Table 8.3-16. The following is an item-by-item analysis of each of these conditions:
General Note The diesel generator will be tripped by (1) generator differential relay, (2) engine overspeed, and (3) low engine lube oil pressure (one-out-of-two taken twice logic) under emergency operation. For test operation, the diesel generator will be tripped by all conditions listed under "Diesel Generator High Priority" alarm as shown on Dwg. E-31, Sh. 9. Following a manual stop, no reset is necessary for subsequent emergency or test operation except the mode selector switch must be returned to "Remote" position. This condition is annunciated locally and in the control room.
Following a trip, the control circuit must be reset. The diesel generator trip is also alarmed locally and in the control room.
There are two engine starting circuits for each diesel generator for added reliability. Each circuit is supplied from the same 125V battery system but through separate circuit breakers. Only one circuit is required for starting the diesel generator.
- 1)
ID-B.1 Generator Differential Relay activated A generator differential relay is provided for each diesel generator for internal fault protection. This relay will trip the diesel generator under any mode of operation. The diesel
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-28 generator differential alarm is annunciated locally and repeated as a group alarm "Diesel Generator High Priority Trouble" in the main control room.
- 2)
ID-B.2 Engine Overspeed Sensor activated An overspeed sensor is provided for each diesel generator. Activation of any one switch from the sensor is alarmed but will not prevent the diesel generator from starting or running.
- 3)
ID-B.3 Engine Lube Oil Low Pressure Relay activated Each of the control circuits have two independent engine lube oil low pressure switches arranged in a one out of two logic. Pressure switches are bypassed during engine starting.
Therefore, alarm is initiated for any one pressure switch (or relay) activation. Disabling of the diesel generator can only be accomplished with one engine lube oil low pressure relay activated in each control circuit.
- 4)
ID-B.4 Operating Mode Switch in Local Operating mode switch (key locked) is put on "Local" for local testing and maintenance services only. "Local position" is annunciated in the main control room as "Diesel Generator not in Auto." Alarm is also indicated in the Bypass Indication System (BIS) on "Diesel Generator Switch in Local" (also in the main control room). Automatic bypass of the "Local" operating mode under emergency condition is not provided. Only one diesel generator will be placed in the "local" operating mode at any one time.
- 5)
ID-B.5 Loss of 125VDC Engine Control Power As discussed above, two separate control circuits are provided for each diesel generator.
Loss of power to either circuit is indicated locally and annunciated in the main control room as "Diesel Generator High Priority." Indication is also provided at the BIS panel. Loss of either circuit will not prevent the diesel generator from starting or operating.
- 6)
ID-B.6 Control Relay Malfunction In order to minimize the effects of a control relay malfunction, most diesel generator control circuits have been designed with redundancy to prevent the disabling of a diesel generator.
Where there are two redundant circuits, a single relay failure will not prevent the diesel generator from starting or operating.
- 7)
ID-B.7 Engine & Generator Mechanical Trouble Low priority and high priority trouble alarms are provided for engine and generator mechanical trouble as shown on Dwg. E-31, Sh. 9 and Table 8.3-16.
- 8)
ID-B.8 Starting Air Control Solenoid Valve Failure There are two starting air solenoid valves for each of the two starting circuits for each D/G.
Loss of any three starting solenoids will not prevent the diesel generator from starting.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-29
- 9)
ID-B.9 Starting Air System Trouble See (9) ID-B.9 and Section 9.5.6 for a complete starting air system discussion. The starting air pressure is monitored at all times with annunciation provided locally and in the main control room.
- 10) ID-B.10 Fuel Oil Control Solenoid Failure One fuel oil control solenoid is provided in each of the two control circuits for each diesel-generator. A failure of either fuel oil control solenoid will not prevent the diesel generator from starting.
- 11) ID-B.11 Loss of 125V DC Generator Control Power Loss of the generator control power will prevent the operation of the excitation system.
Indication is provided at the Bypass Indication System as "DG FLD FLASH and Exciter Power Loss" (Main Control Room).
- 12) ID-B.12 Disabling of Engine and Generator Mechanical Parts During Maintenance Services Before the diesel generator is taken out of the automatic mode for maintenance services, the operating mode selector switch must be in "Local" position as required by maintenance procedures. This will result in an alarm in the main control room as "Diesel Generator not in Auto" ("Diesel Generator Control Switch in LOCAL" in BIS panel).
- 13) ID-B.13 Transfer Switches and Circuit Breakers Not Aligned A transfer scheme described in Section 8.3.1.4 requires all of the transfer switches and 4.16 kV breakers be positioned correctly for a diesel generator to be aligned for emergency operation. Any switch or breaker which is not in the correct position results in an alarm in the main control room as "Diesel Generator Not in Auto" ("Diesel Generator Supply/Control Power Loss" in BIS panel).
No alarms are specifically provided for monitoring of engine and generator mechanical parts under the subject condition.
Conclusion No modifications are necessary as a result of this evaluation because adequate alarms and indications are provided in addition to the alarm redundancy of the control circuits.
8.3.1.5 Electrical Equipment Layout Class 1E switchgear, load centers, motor control centers, and distribution panels of redundant load groups are physically identified and independent from each other in accordance with FSAR Section 3.12.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-30 Standby diesel generators and associated equipment are in separate rooms of the Seismic Category I Diesel Generator A through D building. Each room is provided with a separate ventilation system. A separate seismic Category I Diesel Generator E building contains a diesel generator which can be manually switched to replace one of the Diesel Generators A, B, C or D.
The building has a separate ventilation system.
Plant layout drawings are included in Section 1.2.
8.3.1.6 Reactor Protection System Power Supply The reactor protection system (RPS) power supply is a non-Class 1E system. The normal 120V AC power to each of the two reactor protection systems is supplied, via a separate bus, by its own high inertia motor generator set. The drive motor is supplied from a 480V Class 1E motor control center. High inertia is provided by a flywheel. The inertia is sufficient to maintain voltage and frequency within 5 percent of rated values for at least 1.0 seconds for switching or other transients of short duration on the input power to the drive motor. For a loss of power, the electrical distribution system acts very quickly to dynamically brake the rotating MG Set and trip the generator output breaker.
The alternate 120V AC power for each of the reactor protection systems is supplied by a non-Class 1E motor control center through a 480-120V, 1ø transformer. A selector switch is provided for the selection of the two power supplies. The switch also prevents paralleling the motor generator set with the alternate supply.
The electrical protective assembly (EPA), consisting of Class 1E protective circuitry is installed between the RPS and each of the power sources. The EPA provides redundant protection to the RPS and other systems which receive power from the RPS busses by acting to disconnect the RPS from the power source circuits.
The EPA consists of a circuit breaker with a trip coil driven by logic circuitry which senses line voltage and frequency and trips the circuit breaker open on the conditions of overvoltage, undervoltage and underfrequency. Provision is made for setpoint verification, calibration and adjustment under administrative control. After tripping, the circuit breaker must be reset manually.
Trip setpoints are based on providing 115V AC, 60 Hz power at the RPS logic cabinets. The protective circuit functional range is +/-10% of nominal AC voltage and -5% of nominal frequency.
The EPA assemblies are packaged in an enclosure designed to be wall mounted. The enclosures are mounted on a seismic Category I structure separately from the motor generator sets and separate from each other. Two EPAs are installed in series between each of the two RPS motor-generator sets and the RPS busses and between the auxiliary power sources and the RPS busses. The block diagram in Figure 7.2-9 provides an overview of the EPA units and their connections between the power sources and the RPS busses. The EPA is designed as a Class 1E electrical component to meet the qualification requirement of IEEE 344-1975. It is designed and fabricated to meet the quality assurance requirements of 10 CFR 50, Appendix B.
The enclosures containing the EPA assemblies are designed for normal ambient temperature between 40°F and 122°F. The assemblies are seismically qualified per IEEE 344-1975, to the Safe Shutdown Earthquake (SSE) and Operating Base Earthquake acceleration response spectra.
The enclosure dimensions are approximately 16x20x8 inches and accommodate power cable sizes from 7 AWG to 250 MCM.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-31 8.3.1.7 Class 1E 120V AC Instrumentation and Control Power Supply Four Class 1E 120V AC instrumentation and control power supplies are provided for each unit to supply the two divisions of 120V AC engineered safety feature loads (there are two Division I panels, and two Division II panels). Each power supply consists of a 480-208/120V transformer and a distribution panel. The 480V power supply is energized from a corresponding Class 1E motor control center, which in turn, is energized from a different 4 kV bus (4 kV Buses A and C energize the Division I panels; Buses B and D energize the Division II panels).
There is no manual or automatic transfer between the four 120V AC Class 1E panels.
There is no automatic loading or load shedding of the panels.
Two independent Class 1E inverter backed 120V AC instrumentation power supply systems are provided for the following Control Room instrumentation to supplement other indications available to operators in event of station blackout and optimally support emergency procedures:
Instrumentation selected to meet the Station Blackout Rule is listed in Calculation EC-SBOR-0502.
See FSAR Section 15.9 for a discussion of Station Blackout.
Reactor Vessel Level Reactor Vessel Pressure Suppression Pool Temperature Monitoring Suppression Pool Level Drywell Pressure Drywell Temperature RHR - Heat Exchanger Discharge Temperature Drywell & Wetwell Spray Flow Containment Instrument Gas Bottle Pressure Each inverter is energized from a Class 1E 125V DC battery system and provides 120V AC via associated Class 1E distribution panel, to instrumentation loads continuously under normal operating condition and under DBA LOOP/LOCA condition(s) or 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> station blackout condition.
8.3.1.8 Non-Class 1E Instrument and Vital AC Power Supply Non-Class 1E Instrument AC Power Supply Two 208/120V non-Class 1E instrument AC power supplies (uninterruptible power supplies) per unit furnish reliable power to non-Class 1E miscellaneous instrument systems.
Each instrument AC power supply consists of one uninterruptible power supply (rectifier/charger, inverter, static transfer switch), a dedicated 250V DC sealed maintenance-free battery system, an external maintenance bypass switch panel, and a 208/120V distribution panel. Normally each distribution panel is supplied by a UPS. The preferred supply to the UPS is from a 480V Class 1E motor control center. The alternate supply is via a 480-208/120V transformer from another 480V Class 1E motor control center. A static transfer switch provides the automatic switchover in case of
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-32 an overload or malfunction within the UPS. The external maintenance bypass switch can be positioned to bypass the UPS and supply the distribution panel directly from the alternate supply.
Its position is controlled by plant procedures.
The supplies from the Class 1E 480V MCCs are affiliated circuits. Redundant breakers act as an isolation system between the Class 1E affiliated power supplies and the non-Class 1E loads.
Vital AC Power Supply Two 208/120V non-Class 1E vital AC power supplies (uninterruptible power supplies) per unit supply essential non-Class 1E equipment such as the plant computer. Each vital AC power supply consists of one inverter, automatic transfer switch, manual bypass switch, and distribution panel(s).
Normally, the distribution panel is supplied by the inverter.
The Unit 1 inverter is supplied by a separate Class 1E 250V DC subsystem as described in Subsection 8.3.2. The Unit 2 inverter is supplied by a separate non-Class 1E 250V DC subsystem.
If the inverter is inoperable or is to be removed from service for maintenance or testing, a transfer to the backup supply is made through the manual bypass switch. The backup supply is a regulating type transformer from a 480V Class 1E motor control center. A transfer switch provides the automatic switch-over in case of inverter failure.
The supply from the Class 1E 480V MCC is an associated circuit. Redundant breakers act as an isolation system between the Class 1E power supply and non-Class 1E load.
8.3.1.9 Design Criteria for Class 1E Equipment The following design criteria are applied to the Class 1E equipment.
MOTOR SIZE - Motor size (horsepower capability) is equal to or greater than the maximum horsepower required by the driven load under normal running, runout, or discharge valve (or damper) closed condition.
MINIMUM MOTOR ACCELERATING VOLTAGE GENERAL DESIGN - The electrical system is designed so that the total voltage drop on the Class 1E motor circuits is less than 20 percent of the nominal motor voltage. The Class 1E motors are specified with accelerating capability at 80 percent nominal voltage at their terminals.
SPECIFIC DESIGN - Specific evaluations shall be performed for Class 1E equipment which have additional requirements imposed. The evaluations document the ability of the equipment to perform its safety function at the available terminal voltage. The specific evaluations, in conjunction with the general criteria for Class 1E equipment, confirm operability of Class 1E equipment.
MOTOR STARTING TORQUE - The motor starting torque is capable of starting and accelerating the connected load to normal speed within sufficient time to perform its safety function for all expected operating conditions, including the design minimum terminal voltage.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-33 MINIMUM MOTOR TORQUE MARGIN OVER PUMP TORQUE THROUGH ACCELERATING PERIOD - The minimum motor torque margin over pump torque through the accelerating period is determined by using actual pump torque curve and calculated motor torque curves at 80 and 100 percent terminal voltage. The minimum torque margin (accelerating torque) is such that the pump-motor assembly reaches nominal speed in less than 6.5 seconds. This margin is usually not less than 10 percent of the pump torque.
MOTOR INSULATION - Insulation systems are selected on the basis of the ambient conditions to which the insulation is exposed. For Class IE motors located within the containment, the insulation system is selected to withstand the postulated accident environment.
TEMPERATURE MONITORING DEVICES PROVIDED IN LARGE HORSEPOWER MOTORS - Six resistance temperature detectors (RTD) are provided in the motor stator slots, two per phase, for motors larger than 1500 hp. In normal operation, the RTD at the hottest location (selected by test) monitors the motor temperature and provides an alarm on high temperature.
RTDs are provided for motors from 250 to 1500 hp. Each bearing that is not anti-friction type has a Dual Element Platinum RTD bearing temperature device to alarm on high temperature.
INTERRUPTING CAPACITIES - The interrupting capacities of the protective equipment are determined as follows:
a)
Switchgear Switchgear interrupting capacities are greater than the maximum short circuit current available at the point of application. The magnitude of short circuit currents in medium voltage systems is determined in accordance with ANSI C37.010-1972 (ANSI C37.010 - 1982 for Diesel Generator E). The off-site power system, a single operating diesel generator, and running motor contributions are considered in determining the fault level. High voltage power circuit breaker interrupting capacity ratings are selected in accordance with ANSI C37.06-1971 (ANSI C37.06 - 1979 for Diesel Generator E).
b)
Load Centers, Motor Control Centers, and Distribution Panels Load center, motor control center, and distribution panel interrupting capacities are greater than the maximum short circuit current available at the point of application. The magnitude of short circuit currents in low-voltage systems is determined in accordance with ANSI C37.13-1973, and NEMA AB1. Low-voltage power circuit breaker interrupting capacity ratings are selected in accordance with ANSI C37.16-1970. Molded case circuit breaker interrupting capacities are determined in accordance with NEMA AB1.
ELECTRIC CIRCUIT PROTECTION - Electric circuit protection criteria are discussed in Subsection 8.3.1.3.13.
GROUNDING REQUIREMENTS - Equipment and system grounding are designed in accordance with IEEE 80-1961 and 142-1972.
8.3.1.10 Safety-related Logic and Schematic Diagrams Safety-related logic and schematic diagrams are provided as listed in Section 1.7.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-34 8.3.1.11 Analysis A failure mode effects analysis for the AC power system is presented in Table 8.3-9.
8.3.1.11.1 General Design Criteria and Regulatory Guide Compliance The following paragraphs analyze compliance with General Design Criteria 5, 17 and 18 for the Electric Power Systems. All Regulatory Guides are discussed in Subsections 3.13 and 8.1.6.1.
GENERAL DESIGN CRITERION 5, SHARING OF STRUCTURES, SYSTEMS, AND COMPONENTS Structures, systems, and components important to safety are not shared between nuclear units unless the sharing does not significantly impair their ability to perform their safety function, including, in the event of an accident in one unit, an orderly shutdown and cooldown of the remaining unit.
The two preferred offsite power supplies are shared by both units. The capacity of each offsite power supply is sufficient to operate the engineered safety features of one unit and safe shutdown loads of the other unit.
The Unit 1 AC Distribution System is a shared system between both units, since the common equipment (Emergency Service Water, Standby Gas Treatment System, Control Structure HVAC, etc.) is energized only from the Unit 1 AC Distribution System. There are no Unit 2 specific loads energized from the Unit 1 AC Distribution System. The capacity of the Unit 1 AC Distribution System is sufficient to operate the engineered safety features of one unit and the safe shutdown loads of the other unit.
GENERAL DESIGN CRITERION 17, ELECTRIC POWER SYSTEMS An on-site electric power system is provided to permit functioning of structures, systems, and components important to safety. With total loss of off-site power, the on-site power system provides sufficient capacity and capability to ensure that:
a)
Specified acceptable fuel design limits and design conditions of the reactor coolant pressure boundary are not exceeded as a result of anticipated operational occurrences.
b)
The core is cooled, and containment integrity and other vital functions are maintained in the event of postulated accidents.
Tables 8.3-1 to 8.3-5A list those loads important to safety under design conditions.
The on-site electric power system includes four load groups. The load groups are redundant in that three load groups are capable of ensuring (a) and (b) above. Sufficient independence is provided between redundant load groups to ensure that postulated single failures affect only a single load group and are limited to the extent of total loss of that load group. The redundant load groups remain intact to provide for the measures specified in (a) and (b) above.
During a loss of off-site power, the Class 1E system is automatically isolated from the off-site power system. This minimizes the probability of losing electric power from the on-site power supplies as a result of the loss of power from the transmission system.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-35 Protection, such as voltage restraint overcurrent and 4.16 kV bus differential relays, is provided to trip the diesel generator circuit breaker, if abnormal conditions occur. This protection prevents damage to or shutdown of the diesel generator.
The turbine generator is automatically isolated from the switchyard following a turbine or reactor trip. Therefore, its loss does not affect the ability of either the transmission network or the on-site power supplies to provide power to the Class 1E system. Transmission system stability studies indicate that the trip of the most critical fully loaded generating unit does not impair the ability of the system to supply plant station service. Further discussion is provided in Subsection 8.2.2.
GENERAL DESIGN CRITERION 18, INSPECTION AND TESTING OF ELECTRICAL POWER SYSTEMS The Class 1E system is designed to permit:
a)
Periodic inspection and testing, during equipment shutdown, of wiring, insulation, connections, and relays to assess the continuity of the systems and the condition of components b)
During normal plant operation, periodic testing of the operability and functional performance of on-site power supplies, circuit breakers and associated control circuits, relays, and buses c)
During plant shutdown, testing of the operability of the Class 1E system as a whole, including the system's operational sequence, operation of signals of the engineered safety features actuation system and the transfer of power between the off-site and the on-site power system.
8.3.1.11.2 Safety Related Equipment Exposed to Accident Environment The detailed information on all Class 1E equipment that must operate in an accident environment during and/or subsequent to an accident is furnished in Section 3.11.
8.3.1.11.3 Physical Identification of Safety Related Equipment Each circuit and raceway are given a unique alphanumeric identification, which distinguishes a circuit or raceway related to a particular voltage, function, channel, or load group. One alpha character of the identification is assigned to a load group on the basis of the following criteria:
SEPARATION GROUP CHANNEL A (Red Color Code) - Class 1E instrumentation, controls, and power cables, raceways, and equipment related to Channel A loads, DC subsystem A, 120V AC instrumentation and control channel A, Division I raceways.
SEPARATION GROUP CHANNEL B (Green Color Code) - Class 1E instrumentation, controls, and power cables, raceways, and equipment related to Channel B loads, DC subsystem B, 120V AC instrumentation and control channel B, Division II raceways.
SEPARATION GROUP CHANNEL C (Orange Color Code) - Class 1E instrumentation, controls, and power cables, raceways, and equipment related to Channel C loads, DC subsystem C, 120V AC instrumentation and control channel C.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-36 SEPARATION GROUP CHANNEL D (Blue Color Code) - Class 1E instrumentation, controls, and power cables, raceways, and equipment related to Channel D loads, 120V AC instrumentation and control channel D.
SEPARATION GROUP CHANNEL H (Tan Color Code) - Class 1E instrumentation, controls, and power cables, raceways, and equipment related to the Diesel Generator E Channel H Loads, 120V AC instrumentation and Control Channel H.
SEPARATION GROUP N (Black Color Code) - Non-Class 1E instrumentation, controls, and power cables, raceways, and related equipment.
SEPARATION GROUP DIVISION I (Red/Brown Color Code) - Class 1E instrumentation, control, and power cables.
SEPARATION GROUP DIVISION II (Green/Brown Color Code) - Class 1E instrumentation, control, and power cables.
The affiliated cables are routed with the separation groups they are associated with. The affiliated cables are identified as follows:
a)
Red/Brown - associated with separation group channel A or division I.
b)
Green/Brown - associated with separation group channel B or division II.
c)
Orange/Brown - associated with separation group channel C.
d)
Blue/Brown - associated with separation group channel D.
e)
Tan/Brown - Associated with separation group channel H.
Cable and raceway separation groups are summarized in Table 8.3-10.
For identification of raceways and Class 1E cables refer to Section 3.12.
Design drawings provide distinct identification of Class 1E equipment. The applicable separation group or load group designation is also identified.
Electrical component identification is discussed in Subsection 1.8.6.
8.3.1.11.4 Independence of Redundant Systems Separation Criteria This subsection establishes the criteria and the bases for preserving the independence of redundant Class 1E power systems (For PGCC see Section 3.12).
Raceway and Cable Routing Wherever possible, cable trays are arranged from top to bottom, with trays containing the highest voltage cables at the top. A raceway designated for one voltage category of cables contains only those cables. Voltage categories are:
a) 480V AC, 120V AC, 125V DC and 250V DC power.
b) 120V AC, 125V DC, and 250V DC control and digital signal.
c)
Low level signal.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-37 The 480V AC power, 120V AC control, and digital alarm signal cables originated from the same 480V AC motor control center (MCC) are routed through a common shuttle tray and riser above the MCC. The shuttle tray covers the length of the MCC, and it is used to connect the MCC to the main raceway system via vertical tray risers. The cables are routed in accordance with the above raceway categories once they leave the shuttle tray and vertical tray risers.
The 480V AC power, control and digital alarm signal cables originated from the same motor operated valve (MOV) are routed in a common, unscheduled conduit to an adjacent unscheduled junction box when physical restraints prevent separate conduit entry to the MOV. The cables are routed in accordance with the above raceway categories once they leave the junction box.
Analysis:
When digital alarm signal (annunciator) circuits originate at Motor Control Centers (MCC) or Motor Operated Valves (MOV) where they may be in the proximity of high energy circuits, the annunciator circuits are routed only in non-Class 1E raceway. An impressed voltage or high energy on the annunciator circuit due to a failure of a high energy circuit at the MCC or MOV cannot propagate to redundant Class 1E circuits/systems.
Where the annunciator circuit originates at a Class 1E MCC or MOV, a failure of Class 1E circuits due to an impressed voltage or high energy on the annunciator circuit can only be caused by an initial failure of a Class 1E high energy circuit at the MCC or MOV. This failure is confined to a single channel/division and, therefore, satisfies the single failure criteria.
Where the annunciator circuits originate at a non-Class 1E MCC or MOV, a failure of Class 1E circuits can only be caused by annunciator circuits routed in common raceway. The initial failure of a non-Class 1E high energy circuit at the MCC or MOV must cause multiple failures of annunciator circuits at the point of common routing. The analysis for this type of failure mode is shown in Section 8.1.6.1 (Regulatory Guide 1.75 (1/75), Part 7).
These conditions do not invalidate the separation exemption of Section 8.1.6.1 (Regulatory Guide 1.75 (1/75), Part 7) because of the extremely remote possibility of resulting in a common mode failure.
15 kV and 5 kV class cables are normally routed in conduits only; however, solid bottom tray with solid top covers or wireway may be utilized.
Cables corresponding with each separation group, as defined in Subsection 8.3.1.3, are run in separate conduits, cable trays, ducts, and penetrations.
Refer to Subsection 3.12.3.4.2 for description of physical separation of raceway and cable routing.
8.3.1.11.5 Administrative Responsibilities and Controls for Ensuring Separation Criteria The separation group identification described in Subsection 8.3.1.11.3 facilitates and ensures the maintenance of separation in the routing of cables and the connections. At the time of the cable routing assignment during design, those persons responsible for cable and raceway scheduling ensure that the separation group designation on the scheme to be routed is compatible with a single-line-diagram load group designation and other schemes previously routed. Extensive use of computer facilities assists in ensuring separation correctness. Each cable and raceway is identified in the computer program, and the identification includes the applicable separation group designation. Auxiliary programs are made available specifically to ensure that cables of a
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-38 particular separation group are routed through the appropriate raceways. The routing is also confirmed by quality control personnel during installation to be consistent with the design document. Color identification of equipment and cabling (discussed in Subsection 8.3.1.11.3 and Section 3.12) assists field personnel in this effort.
8.3.2 DC POWER SYSTEMS 8.3.2.1 Description The DC power systems are divided into Class 1E and non-Class 1E systems.
8.3.2.1.1 Class 1E DC Power System The Class 1E DC system is shown on Dwgs. E-11, Sh. 1, E-11, Sh. 11, and E-13, Sh. 1. The DC system for each generating unit consists of four 125V DC subsystems, two 250V DC subsystems, and two +/-24V DC subsystems. The Diesel Generator E building has a 125V DC subsystem.
8.3.2.1.1.1 125V DC Subsystems Four Class 1E 125V DC power subsystems provided for each unit are located in separate rooms in the control structure. These four subsystems are identified as channels A, B, C, and D. Each subsystem provides the control power for its associated Class 1E AC power load group channel:
4.16 kV switchgear, 480V load centers, and standby diesel generator as discussed in Subsection 8.3.1. Also, these DC subsystems provide DC power to the engineered safety feature valve actuation, diesel generator auxiliaries, and plant alarm and indication circuits.
The Diesel Generator E 125V DC power subsystem is located in the basement of the Diesel Generator E building. The subsystem is identified as Channel H and provides DC power to ESW valves and control power to Class 1E 4.16 kV switchgear and the standby diesel generator in the Diesel Generator E building.
Each 125V DC subsystem consists of one load center, one Class 1E and one non-Class 1E distribution panel, one 125V battery bank, and one battery charger. The non-Class 1E distribution panel is connected to the Class 1E DC power supply through an isolation system. The isolation system is defined in Section 8.1.6.1 (Regulatory Guide 1.75). The battery charger of each system is supplied with 480V Class 1E AC power from the motor control center associated with the same load group channel.

SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-39 The 125V dc subsystem charger output voltage can be regulated at two different control points.
One is a variable resistor located inside the cabinet and is used for rough voltage settings. The other is a screwdriver adjusted potentiometer located on the front of the cabinet and is used for fine adjustments. By setting both controls at their maximum positions, the charger output voltage would be 145.2 volts. The diesel generator E 125V dc subsystem battery charger has one control point and the charger output voltage can be adjusted to 145 volts. All equipment or devices connected to the 125V DC supply are rated 105V to 144V DC, unless plant specific analyses have been performed to justify other voltage levels.
There are no overvoltage protection devices provided for the 125V DC subsystem. There is an overvoltage alarm in the control room for the 125V dc subsystem. "The 125V DC power is distributed through circuit breaker type distribution panels. The 125V DC loads are shown in Table 8.3-6A, 8.3-6B, 8.3-6C, 8.3-6D, 8.3-6E, 8.3-6F, 8.3-6G, 8.3-6H, and 8.3-6I."

However, the Class 1E MCC's are located in a seismic Category I structure while the non-Class 1E MCC's are located in a non-seismic Category I structure (Turbine Building).
The charger output voltage can be regulated at two different control points. One is a variable resistor located inside the cabinet and is used for rough voltage settings. The other is a screwdriver adjusted potentiometer located on the front of the cabinet and is used for fine adjustments.

SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-41 The capacity of each battery charger, is based on the largest combined demand of all the steady-state loads and the charger current required to restore the battery from the design minimum charged state to the fully charged state after a design basis event discharge to the fully charged state within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> for Division I and II 250 VDC subsystems and class 1E 125 VDC subsystems; within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> for class 1E 24 VDC subsystems, and within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> for class 1E Diesel Generator E 125 VDC subsystem.
The battery chargers are constant voltage type with capability of operating as battery eliminators and would function properly with battery disconnection being a normal condition. The battery eliminator feature is incorporated as a precautional measure to protect against inadvertent disconnection of the battery. There are no planned modes of operation which would require battery disconnection. Variation of the charger output voltage has been determined by testing to be less than 1% with or without the battery connected. Maximum output ripple for the 24V and 125V DC chargers is 30 millivolts RMS with or without the battery, and 200 millivolts for the 250V chargers. For the Diesel Generator E the maximum output ripple for the 125V DC charger is 100 millivolts with the battery connected and 300 millivolts with the battery disconnected.
The failure mode and effect analysis for the +/-24V DC subsystem is shown in Table 8.3-23.
Each 125V, 250V, and +/-24V battery bank has sufficient capacity without its charger to independently supply the required loads for 4 hr as shown in Tables 8.3-6A, 8.3-6B, 8.3-6C, 8.3-6D, 8.3-6E, 8.3-6F, 8.3-6G, 8.3-6H, 8.3-6I, 8.3-7A, 8.3-7B, 8.3-7C, 8.3-7D, 8.3-7F, 8.3-7G, 8.3-7H, 8.3-7I, and 8.3-8 respectively.
In accordance with IEEE 485-1978 initial rated battery capacity for Class 1E batteries is 25 percent greater than required. This margin allows replacement of the battery to be made when its capacity has decreased to 80 percent of its rated capacity (100 percent of design load).

8.3.2.2 Analysis 8.3.2.2.1 Compliance with General Design Criteria, Regulatory Guides, and IEEE Standards The following paragraphs analyze compliance of the Class 1E DC power systems with General Design Criteria 17 and 18, Regulatory Guides 1.6, 1.32, 1.41, 1.81, and 1.93, and IEEE 308, 450, 484 and 485. An
- beside the effective date of the Regulatory Guide or IEEE standard listed indicates the guide or standard applicable to the plant is applicable to Diesel Generator E.
a)
General Design Criterion 17, Electric Power Systems Consideration of Criterion 17 leads to the inclusion of the following factors in the design of the DC power systems:
- 1)
Separate Class 1E 125V DC subsystems (A through D) supply control power to their respective Class 1E AC load groups. The four load groups are subgrouped to form two divisionalized load groups (Division I and II) for those ESF loads requiring one-out-of-two load groups to meet the design basis requirements.
Some divisionalized loads powered from the Class 1E 4 kV Buses C and D are supplied DC control power from the Class 1E 125V DC Channels A and B, respectively (i.e., RHRSW, ESW, CRD, CS Chiller).
- 2)
The AC power for the battery chargers in each of these DC subsystems is supplied from the same AC load group for which the DC subsystem supplies the control power.
- 3)
Two independent 250V DC subsystems are provided to ensure the availability of the DC power system for maintaining the reactor integrity during postulated accidents.
- 4)
The Class 1E DC subsystems including batteries, chargers, DC switchgear, and distribution equipment are physically separate and independent.
- 5)
Sufficient capacity, capability, independence, redundancy, and testability are provided in the Class 1E DC subsystems, ensuring the performance of safety functions assuming a single failure.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-45 b)
General Design Criterion 18, Inspection and Testing of Electric Power Systems Each of the Class 1E subsystem is designed to permit:
- 1)
Inspection and testing of wiring, insulation, and connections during equipment shutdown to assess the continuity of the subsystem and the condition of its components.
- 2)
Periodic testing of the operability and functional performance of the components of the subsystems during normal plant operation.
The Class 1E DC subsystems are periodically inspected and tested to assess the condition of the battery cells, charger, and other components in accordance with Chapter 16. Preoperational testing is discussed below in assessment of compliance with Regulatory Guide 1.41.
c)
Regulatory Guide 1.6 (1/71)*
The design of the DC system complies with Regulatory Guide 1.6. Separate Class 1E 125V DC subsystems (A through D) supply control power to their respective Class 1E AC load groups. The four load groups are subgrouped to form two divisionalized load groups (Division I and II) for those ESF loads requiring one-out-of-two load groups to meet the design basis requirements. Some divisionalized loads powered from the Class 1E 4 kV Buses C and D are supplied DC control power from the Class 1E 125V DC Channels A and B, respectively (i.e., RHRSW, ESW, CRDC, CS Chiller). Loss of any one of the subsystems does not prevent the minimum safety function from being performed. The 125V DC subsystem chargers are supplied from the same AC load group for which the DC subsystem supplies the control power. Each of the four 125V DC subsystems, including battery bank, charger, and distribution system, is independent of other 125V DC subsystems. In addition to the four DC subsystems, the Diesel Generator E building 125V DC subsystem includes a battery bank, charger and distribution system for operation of Diesel Generator E. The DC subsystem is independent of the other four DC subsystems. Thus, sufficient independence and redundancy exist between the 125V DC subsystems to ensure performance of minimum safety functions, assuming a single failure.
Two independent Class 1E 250V DC subsystems are provided. Each subsystem is independent of the other. Sufficient independence and redundancy exist in these subsystems so that a single failure in the 250V DC subsystems does not prevent the performance of minimum safety functions.
Two independent Class 1E +/-24V DC subsystems are provided. Each subsystem is independent of the other. Sufficient independence and redundancy exist in these subsystems so that a single failure in the +/-24V DC subsystems does not prevent the performance of minimum safety functions.
d)
Regulatory Guide 1.32 (3/76) (Diesel Generators A-D)
The battery charger capacity for each of the Class 1E DC subsystem complies with this Regulatory Guide.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-46 Each Class 1E battery charger has sufficient capacity to supply the largest combined demand of the various steady-state loads and the charging current required to restore the battery from the design minimum charge state to the fully charged state irrespective of the status of the plant during which these demands occur.
The test interval for the battery modified performance discharge test and the service test is in accordance with the Technical Specifications.

Each generating unit is provided with separate and independent on-site DC electric power systems capable of supplying power to the control systems of engineered safety features loads and loads such as valves, and actuators, required for attaining a safe and orderly cold shutdown of the unit, assuming a single failure.
The common systems which are required for both Unit 1 and 2 operation, are provided with two sources of 125V DC control power, through a manual transfer switch. The Class 1E loads will be capable of being transferred between the Unit 1 and corresponding Unit 2 source. The non-Class 1E loads are primarily fed from two different Unit 1 sources. Some non-1E loads are fed from a Unit 1 or Unit 2 source.

- 2)
The 250V DC and +/-24V DC systems are each separated into two subsystems.
- 3)

- 5)
The batteries are not interconnected.
Each Class 1E distribution circuit is capable of transmitting sufficient energy to start and operate all required loads in that circuit. Distribution circuits to redundant equipment are independent of each other. The distribution system is monitored to the extent that it is shown to be ready to perform its intended function. The DC auxiliary devices required to operate equipment of a specific AC load group are supplied from the same load group.
Each battery supply is continuously available during normal operations and following the loss of power from the AC system to start and operate all required loads.
The 125V DC and 250V DC subsystems are ungrounded; thus, a single ground fault does not cause immediate loss of the faulted system. Ground detection and alarm is provided for each DC subsystem so that ground faults can be located and removed. The +/-24V DC subsystem is grounded.
Equipment of the Class 1E DC system is protected and isolated by fuses or circuit breakers for short circuit or overload protection. The following instrumentation is provided to monitor the status of each of the DC subsystems:
System undervoltage System overvoltage System ground Battery availability Battery charger trouble - AC undervoltage; DC overvoltage charger failure; charger output breaker trip Load center breaker trip (250V DC subsystem only)
All above alarms are annunciated as a group alarm in the main control room.

+/-24V DC subsystems:
Positive bus low voltage Negative bus low voltage Positive bus high voltage Negative bus high voltage Battery availability Battery charger trouble - AC failure; charger failure; charger output breaker trip All above alarms are annunciated in the main control room as +/-24V DC system trouble, a group alarm for each battery bank and its associated system.
The batteries are maintained in a fully charged condition and have sufficient stored energy to operate all necessary circuit breakers and to provide an adequate amount of energy for all required emergency loads for four hours after loss of AC power.
Each battery charger has an input AC and output DC circuit breaker for isolation of the charger. Each battery charger power supply is designed to prevent the AC supply from becoming a load on the battery due to a power feedback as the result of the loss of AC power to the chargers.
The battery charger AC supply breaker can be periodically opened to verify the load carrying ability of the battery.
The batteries, battery chargers, and other components of the DC subsystems are housed in the control structure, which is a Seismic Category I structure. The Diesel Generator E 125V DC subsystem is housed in the Diesel Generator E building which is a seismic Category I structure.

Correction factors for the number of conductors in the cable and for the actual cable diameter are applied in accordance with IPCEA P-54-440.
Ampacity values listed in IPCEA P-54-440 are for five discrete values of calculated depth of cables in tray. The ampacity value for any cable depth value other than the values stated in the IPCEA P-54-440 tables are determined by linear interpolation. The linear interpolation is performed for values of cable depth, X, applicable to percent fills greater than or equal to 30%
for cable tray with 3 cable loading depth and percent fills greater than or equal to 18% for cable tray with 5 cable loading depth.
The percent fill of the cable tray is converted to an equivalent calculated depth of cable in tray from the formula:
Calculated depth (X) d x
4 x
100 Fill
where: d = the useable cable loading depth of the cable tray (inches)

SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-52 Wrapped Raceway See Fire Protection Review Report (FPRR) Section 4.11, for wrapped raceway derating factors.
For control circuits, minimum #14 AWG conductors are generally used.
Instrumentation cable is also designed for a conductor temperature of 90°C. Operating currents of these cables are low (usually mA or mV) and will not cause the design temperature to be exceeded at maximum design ambient temperature.
In general, cable tray fill is limited to 30 percent fill by cross-sectional area. In cases where the limitation is exceeded, a review will be performed for each case for the adequacy of the design.
In general conduit fill is in compliance with Tables I and II, Chapter 9, National Electrical Code, 1975 (National Electric Code, 1981 for Diesel Generator E). In cases where these values are exceeded, a review is performed for each case to insure the adequacy of the design.
Power cables, control cables, and instrumentation cables are defined as follows:
Power Cables Power cables are those cables that provide electrical energy for motive power or heating to all 13.8 kV AC, 4.16 kV AC, 480V AC, 120V AC, 250V DC, and 125V DC loads.
Control Cables Control cables, for the purpose of derating, are generally 120V AC, 250V DC, 125V DC, and 24V DC circuits between components responsible for the automatic or manual initiation of auxiliary electrical functions and the electrical indication of the state of auxiliary components.
Instrumentation Cables Instrumentation cables are those cables conducting low-level instrumentation and control signals.
These signals can be analog or digital. Typically, these cables carry signals from thermocouples, resistance temperature detectors, transducers, neutron monitors, etc.
8.3.3.2 Fire Detection for Cable Systems Fire detection systems are discussed in Subsection 9.5.1.
8.3.3.3 Fire Barriers and Separation Between Redundant Trays Electrical equipment and cabling has been arranged to minimize the propagation of fire from one separation group to another. Physical separation of cabling systems is discussed in Subsection 3.12.2.
Where the minimum physical separation cannot be met as specified in Subsection 3.12.2, and a fire barrier is selected as the alternative, a 1/4 inch Haysite ETR-FR-C is installed. The bolts and hardware used to secure the Haysite panel to the tray support are coated after installation with 1/8 in. of fireproofing material Dynatherm's Flamemastic 71A compound.
SSES-FSAR Text Rev. 78 FSAR Rev. 71 8.3-53 8.3.3.4 Fire Stops Fire stops and seals are provided for cable penetrations in the floor for vertical runs of raceways, at each access opening in ceilings and at fire-rated wall penetrations. The fire stops are furnished to provide a method of sealing off air spaces around cable penetrations. The properties of materials and qualification tests are discussed in Subsection 9.5.1.

10 sec NOTES:
- Manual Initiation
- Same Loop
- 1.
MOV Loads are not included in diesel generator loading because of small magnitude and short duration.
- 2.
Diesel generators A, B, C, and D are rated as follows:
4000 KW continuous 4700 KW -- 2000 hrs Diesel Generator E is rated as follows:
5000 KW continuous 5500 KW - 2000 hrs
- 3. Loading Sequence based on loss of offsite power. Unit 1 LOCA and Unit 2 shutdown is assumed. Loading sequence of the RHR and Core Spray Pumps with offsite power available is different as indicated in Table 8.3-1b.
- 4.
Diesel generator starting time of 10 sec is assumed.
- 5.
Deleted
- 6.
Timing shown in parenthesis applies to the backup load when it has a different starting time than the primary load. Backup loads will operate when power is lost to the primary load.
SSES-FSAR Table Rev. 63 FSAR Rev. 71 Page 8 of 8 Table 8.3-1 Assignment of ESF and Selected Non-ESF Loads to Diesel Generators and ESS Buses NOTES:
- 7.
Load tripped automatically within 10 min.
- 8.
Normal supply to 1D130 & 2D130 is from Diesel Generator D, alternate supply is from Diesel Generator B.
Normal supply to 1D240 & 2D240 is from Diesel Generator C, alternate supply is from Diesel Generator A.
When Diesel Generators C or D are unavailable, 1D130 et al should be shown as loads on their alternate supply.
Operating Kw of 1D240 is shown as UPS + Dist Panel Load/Dist Panel Load; eg. 39/34: (39 = UPS Load + Panel Load and 34 = Panel Load)
- 9.
This load is connected to the Diesel Generator E bus. Where indicated in the Loading Sequence portion of Table 8.3-1, the load will operate when Diesel Generator E is substituted for Diesel Generators A, B, C or D.
- 10. The maximum allowable loads will be used to load the diesel generators. The maximum allowable loads are based on the equipment rating as documented in the diesel generators load calculation.
- 11. Intentionally left blank.
- 12. Selected non-ESF loads are connected to the diesel backed buses to provide protection to non-ESF equipment. The non-ESF loads are not required for mitigation of a design basis accident of one unit and concurrent safe shutdown of the second unit. The non-ESF load timing is still shown to provide information for when the load is started from the time of DBA.
- 13. The preferred source for Vital AC UPS is fed by diesel generator B backed up bus. If diesel generator B fails then the source of power will be from a battery bank which is sized to supply the load for four hours. After four hours, the UPS will be transferred to the alternate source which is fed by diesel generator D backed up bus.
- 14. Due to its intermittent operation, it is not considered a load on the diesel generator.
- 15. Fan starts automatically following manual initiation of related pump.
- 16. The Design Basis Accident (DBA) specifically utilized for the compilation of Minimum Required Number is a complete shear on the suction side of the recirculation pipe.
- 17. Only one Loop RHRSW with on RHRSW pump running is required to remove decay heat for both units. For purposes in demonstrating diesel loading as a result of the RHRSW alignment, the FSAR Diesel loading tables show two RHRSW pumps in operation, one for the unit with a DBA and one for the shutdown unit which indicate the maximum possible RHRSW pumps per diesel loading.
