IDENTIFICATION OF SIMILAR NUCLEAR POWER PLANTS Wolf Creek is one of five nuclear power plants that were to be constructed as part of the Standardized Nuclear Unit Power Plant Systern (SNUPPS) project. The l SNUPPS plant design is based on a standard Westinghouse 4 loop PWR nuclear steam supply system. Originally the SNUPPS project included single unit plants at Wolf Creek, Tyrone (Northem States Powed, and Sterling (Rochester Gas and Electric), and a twin unit plant at Callaway (Union Electric). Only Wolf Creek and a single unit at Callaway were actually completed. Other four loop Westinghouse plants in the United States include: Braidwood I and 2 Byron 1 and 2 Catawba Comanche Peak 1 and 2 l - Donald C. Cook 1 and 2 (ice condenser containment) Diablo Canyon 1 and 2 Haddam Neck Indian Point 2 and 3 McGuire 1 and 2 (ice condenser containment) Millstone 3 Salem 1 and 2 Seabrook1 Sequoyah and 2 (ice condenser containment) Shearon Harris 1 and 2 South Texas 1 and 2 O - Trojan V - Vogtle I and 2 Watts Bar 1 and 2 1 1/89 c
Wolf Creek Yankee Rowe 6; Zion 1 and 2 k Wolf Creek is generally similar to the other plants in the number and type of charging and high pressure iniection aumps. Differences tetween Wolf Creek and Callaway (the two completed SNUPPS p ants) are listed below:
- Ultimate IIcat Sink for the Essential Service Water System The ESWS at Wolf Creek draws water from a 6000 acre cooling lake on the Neosho River near the plant and returns it to the lake. The ESWS at Callaway draws water from a retention pond containing over 51 acre feet of water and returns water to the pond via inechanical draft UHS cooling towers.
Heat Sink for the Service Water and Circulating Water Systems The 600() acre cooling lake is the normal water source and heat sink for the Wolf Creek Service Water and Circulating Water Systems. At Callaway, this funcuon is perfont.ed by a closed loop for heat rejection to the atmosphere. Makeup to this system is provided from the Missoun River which is five miles from the plant.

Wolf Creek 1 /D b 3.1 RI: ACTOR COOLANT SYSTEM (RCS) i 3.1.1 Ss stem Function
'T he RCS transf ers heat from the reactor core to the secondary coolant system via the steam generators. The RCS pressure boundary also establishes a boundary against l the uncontrolled release of radioactive material from the reactor core and primary coolant.
3.1.2 System Definition
'I he RCS includes: (a) the reactor vessel, (b) reactor coolant loops, (c) reactor coolant pumps, (d) the primarv side of the steam generators, (c) pressurizer, and (f) connected piping out to a suitable isolation valve boundary. An isometric drawing of a 4-loop Westinghouse RCS is shown in Figure 3.1 1. A simalified diagram of the RCS and important system interfaces is shown in Figures 3.12 and 3.13. A summary of data on selected RCS components is presented ir Table 3.1 1.
3.1.3 Ssstem Ooeration Dunng power operation, ciret.'ation in the RCS is maintained by one reactor coolant pump in each of the four reactor coo' ant loops. RCS pressure is maintained within l a present>ed band by the combined action of pressurizer heaters a..d pressurizer spray. t RCS coolant invento'ry is measured by pressurizer water level which is maintained within a prescribed band by the chemical and volume contwl system (charging system). At power, core heat is transferred to secondary coolant (feedwater)in the steam generators. The heat transfer path to the ultimate heat sink is completed by the main steam and power conversion system and the circulating water system, p Following a transient or smLil LOCA (if RC$ inventory is maintained), reactor Q core heat is still transferred to secondan coolant in the steam generators. Flow in the RCS is maintained by the reactor coolant pumps or by natural circulation. The heat transfer path to the ultimate heat sink can be established by using the secondary steam relief system (see Section 3.2) to vent main steam to atmosphere when the power conversion and circulating water systems are not available. If reactor core heat removal by this alternate path is not adequate. the RCS pressure will increase and a heat balance will be established in the RCS by venting steam or reactor coolant to the containment through the pressurizer relief valves. There are two power-operated relief valves (each in series with 1. motor operated block l valve), and three safety valves on the pressurizer. A continued inability to establish ! adequate heat transfer to the steam generators will result in a LOCA like condition (i.e. continuing loss of reactor coolant through the pressurizer relief valves). Repeated cycling i i of these relief valves has resulted in valve failure (i.e. relief vah c stuck open). ! Following a large LOCA, reactor core heat is dumped to the containment as ! reactor ecolant and ECCS makeup water spills from the break. For a short-temi period, the containment can act as a heat sink: however, the containment cooling systems must operate in order to complete a heat transfer path to the ultimate heat sink (see Section 3.9). 3.1.4 System Success Criterin TheasRCS mitigation, success follows: criteria can be described in terms of LOCA and transient An unmitigatible LOCA is not initiated. If a mitigatible LOCA is initiated, then LOCA mitigating systems are successful. If a transient is initiated, then either: (A d RCS integrity is maintained and transient mitigating systems ire successful, or RCS integrity is not maintained, leading to a LOCA likt condition (i.e. 8 12/88
Wolf Creek stuck open safety or relief valve, reactor coolant pump seal failure), and LOCA mitigating systems are successful. 3.1.5 Comoonent Information A. RCS

- 1. The reactor coolant pumps are supplied from Non Class IE switchgear.
- 2. Two banks of pressurizer backup heaters can be supplied from the Class 1E power system via 480 VAC buses PG21 and PG22. The supply circuit breakers for these buses are automatically tripped by the load shedder /
sequencer foliowing an SI AS or essential bus undervoltage signal. B. Reactor Coolant Pump Seal Injection Water System The chemical volume and control system supplies seal water to cool the reactor coolant pump shaft seals and to maintain a controlled inleakage of seal water into the RCS. Loss of seal water flow may result in RCS leakage through the pump shaft seals which will resemble a small LOCA. I v\ 9 12/88

Wo f Creek ( 3.2 Al'XILI ARY FEEDWATER (AFW) SYSTEM AND SECONDARY STEAM RELIEF (SSR) SYSTEM 3.2.1 Ssstem runction '
'Ihe AlW system provides a source of feedwater to the steam generators to remove heat from the reactor coolant system (RCS) whem (a) the main feedwater system is not available, and (b) RCS 1ressure is too high to permit heat removal by the residual heat removal (RHR) system. "he SSR system provides a steas.1 vent path from the steam generators to the atmosphere, thereby completing the heat trusfer path to an ultimate heat sint when the main steam and power conversion systems are not available. Together, the AFW and SSR systems constitute an open loop fluld systern that provides for heat transfer from the RCS following transients and small break LOCAs.
3.2.2 System Definition The AFW system consists of two motor-driven pumps and one turbine driven pump. Water is supplied to the AFW pumps from the condensate storage tank (CST). The Essential Service Water System (ESWS)is the backup water source for the AFW pumps. 1 The turbine driven AFW pump can supply all four steam generators. Each motor dnven pump nonnally is aligned to sup? ly two steam generators. The SSR system ine udes five safety valves and one power operated pressure i relief valve on each of'the four main steam lines. Simplified drawings of the AFW and SSR systems are show n in Figures 3.21 and 3.2 2. A summary of data on selected AFW system components is presented in Table 3.2 1. 3.2.3 System Ooeration i Dunng nonnal operation the AFW system is in standby, a id is automatically actuated on either a low low level in any two of four steam generators, a safety injection < signal, a loss of both main feedwater pumps, or a loss of offsite and station nonnal auxiliary power. The system can also be manually started from the control room. AFW system success criteria are defined as delivery of 470 gpm to a minimum of two steam generators before they boil dry (about 25 minutest Ordinarily, the AFW system is required to operate for about 2 hours to maintain the reactor at hot standby followed by cooldown of the Reactor Coolant System to aparoximately 350*F and 40U psig. The residual heat removal (RHR) system may then je initiated to continue the cooldown (Ref.1). The turbine driven AFW pump is capable of providing 1145 gpm, which is more than twice the capacity required for AFW system success. This pump is ca 3able of supplying its own cooling and lubrication independently of AC power, but wien AC power is available backup The two motor-driven AF% pumps are provid 3 for oil pressure and water jacket cooling. pumps are capable of providing 575 gpm each.' The CST is the nonnal water source for all AFW pumps. The backup source for motor driven AFW pump A is ESW train A. Motor dnven AFW pump B can be supplied from ESW train B, and the turbine driven AFW pump can be supplied from either ESW train. Motor driven AFW pump A normally su AFW pump B supplies steam generators Two A and D.pplies normally steam closed valvesgenerators may be B and C, w opened manually to allow the motor driven pumps to feed any of the steam generators. The turbine-driven pump can supply all of the steam generators, but only steam generators B and C can supply steam to drive the AFW pump's turbine. O V 14 12/88
l , Wolf Creek b 3.2.4 Ssstem Success Crlferla For the decay heat removal function to be successful, both the ARY system and the SSR system must operate successfully. The ARY success criteria are the following (Ref.1): hiakeup to any two steam generators provides adequate decay heat removal i from the Reactor Coolant System. Any one AFW pump can provide adequate flow to supply two steam , generators. Either the CST or the ESWS can serve as an adequate water source for the ARY system as follows: ARV Pumns Water Source Turbine driven pump CST or ESWS A or B 1 hiotor driven pump PI A CSTor ESWS A j hiotor driven pump P1B CST or ESWS B j 3.2,5 Comoonent Information A. 510 tor driven ARY pumps P1 A and PIB

Wolf Creek 3.3 EMERGENCY CORE COOLING SYSTEM (ECrS) 3.3.1 Ss stem Function The LCCS ts an integrated set of subsystems that perfonn emergency coolant injection and recirculation functions to maintain reactor core coolant inventory and adequate decay heat removal following a LOCA. The coolant injection function is performed during a relatively short term period after LOCA initiation, followed by realignment to a recirculation male of operation to maintain long term, post LOCA core cooling. llent from the reactor core is transferred to the containment. The heat transfer path to the ultimate heat sink is completed by the RHR system operating in the recirculation mode and the containment cooling system (see Section 3.9). 3.3.2 System 1)crinition The emergency coolant injection (ECI) function is performed by the following ECCS subsystems: Passive cold leg accumulators Safety injection (SI) system Charging system (CVCS) Residual heat removal (RilR) system The safety in high pressure coolant in,iection tection (SI)RHR function and pumpspumpsand the centrifugal perform chargiru the ow pressure coolantpumps perform injection function. The kefueling Water Storage Tank (RWST)is the water source for both the high and low pressure injection systems. Both systems normally are aligned to inject coolant into all four RCS cold legs. the SlS can be aligned to inject into all four hot legs, w hile the RHR system can be aligned to inject into two hot legs. After the injection phase is completed, low pressure recirculation is perfonned by the RHR pumps drawing suction from the containment recirculation sumps and dis:hr %ng into the RCS cold legs. Heat is transferred to the component cooling water system ty the RHR heat exchangers. The RHR pumps can also deliver water to the suctions of the Si pumps and the centrifugal charging pumps for high pressure recirculanon. Long-term core decay heat removal is perfomied by the RHR system and the containment cooling system (see Section 3.9). Simplined drawings of the safety injection system (SIS) are shown in Figures 3.31 and 3.3 2 _ The RHR system is shown in Figures 3,3 3 and 3.3 4. The charging system is described in Section 3.4. Interfaces between the accumulators, the ECCS injection and recirculation subsystems, and the RCS are shown in Section 3.1. A summary of data on selected ECCS components is presented in Table 3.31. 3,3,3 System Ooeration During normal operation, the ECCS is in standby, Following a LOCA, the four cold leg injection accumulators (one for each loop) supply borated water to the RCS as soon as RCS pressure drops below accumulator pressure (approximately 650 psig). A safety injection signal (SIS) automatically starts the centrifugal charging pumps, the safety injection pumps, and the RHR , pumps, and aiigns & centrifugal charging pumps for injection. The centrifugal charg ng pumps inject througn the boron injection tank (BIT) into the four RCS cold legs. The Si and RHR pumps normally inject into the cold legs, but also can be aligned for hot leg injection. All pumps nomially are aligned to take suction on O \ / the RWST. For small breaks, operator action can be taken to augment the RCS-depressurization by utilizing the secondary steam dump capability and the auxiliary feedwater (AFW) system (i.e., depressurization due to rapid heat transfer from the RCS).. 20 12/88
Wolf Creek [ When the RWST water level drops to a prescribed low level serpoint, the RHR pump 3 are realigned to draw a suction from the containment sumps and deliver water to the RCS. If depressuriration of the RCS proceeds slowlv, high pressure recirculation can be accomphthed by manually aligning the discharge of the RHR pumps to the suction of the centrifugal charging and Si pumpi 3.3.4 System Success Criteria LOCA mitigation requires that both the emergency coolant injection and emergency coolant recirculation functions be accomplished. The ECl success criteria for 1.OCAs are not clear in the FS AR, however, the following is noted: A .365 inch diameter break is the maximum break size for which the normal makeup system can maintain the pressurizer level and the nonnal reactor coolant system pressure of 2250 psia. For a break of this size, one centrifugal charging
) ump is adequate to sustain pressurizer level at an RCS pressure of 2250 psia.
11is break results in a loss of approximately 17.5 lb/sec (127 gpm at 130^F and 2: 50 psia) (Ref.1 ). Fe a small break LOCA the high head portion of the ECCS, together with the act umulators, provide suf0cient core flooding (Ref.1) For a large break LOCA in which the break is in one injection path, three accumulators, one charging pump, one safety injection pump, and one residual heat removal pump provide sufficient core flooding (Ref. 2). p 3,3,5 Comoonent Information A.

Wolf Creek 3.4 CllARGING SYSTEM 3.4.1 System Function The charging system is part of the Chemical and Volume Control System' r
'CYCS) and the Emergency Core Cooling System (ECCS). The CVCS is responsible for maintaining the proper water inventory in the Reactor Coolant System and maintaining water purity and the proper concentration of neutron absorbing and corrosion inhibiting
,l chemicals in the reactor coolant. The normal makeup function of the CVCS is required to maintain the plant in a long-term hot shutdown condition following a transient. As part of the ECCS, the charging system performs high pressure emergency coolant injection and recirculation functions to maintain reactor coolant inventory and' adequate decay heat removal following a LOCA.
3.4.2 System Definition - The CVCS consist 3 of several subsystems: the charging, letdown, seal. water collection system, the reactor coolant puri0 cation and chemistry control system, the reactor makeup control system, and the baron thermal regeneration system. The CVCS includes the following: three charging pumps (one positive displacement and two centrifugal pumps) three independent charging now paths to the RCS (normal charging reactor-coolant pump seal injection end boron injection tank paths) two letdown flow paths from the RCS (normal and excess letdown paths). two borated water sources for the charging pumps (volume control tank and s refueling water storage tank) various demineralizers, filters, and.other subsystems -for maintaining coolant purity, pH, and chemical concentration Simplified drawings of the CVCS, focusing on the charging portion of the 3 system, are shown in Figures 3.41 and 3,4-2. A summary of data on selected CVCS
- components is presented in Table 3 A .I.
1 3.4,3 Svstem Oneration During normal operation, CVCS letdown flow is 75 gpm and the positive - displacement charging pump is operating to provide RCS makeup. Pump speed is-controlled to maintain pressurizer level in the prescribed range .During normal operation with maximum purification, letdown flow is 120 gpm, and makeup is provided by one centrifugal charging pump. Charging flow is modulated by flow control valve 121 to maintain pressurizer level in the prescribed range. The letdown flow from the reactor _ coolant system is cooled by the regenerative heat exchanger and the letdown heat exchanger, and pressure is reduced along the letdown flow; path to the mixed bed - demineralizer. Boron concentration is adjusted before the letdown flow is directed to the-Volume Control Tank (VCT). All charging pump; normally are aligned to take suction on the VCT, The charging pamps are aligned to take a suction on the Refueling . Water Storage Tank (RWST) when the VCT water level cannot be adequately maintained or when a Safety Injection Signal (SIS) is present. When an SIS occurs, normal operation of the CVCS is terminated (letdown line is isolated) and makeup to the RCS is provided by both centrifugal charging pumps injecting via the boron injection tank into all four RCS colo 3 legs. When needed, an ECCS high pressure recirculation flow path can be established . with the RHR pumps taking a suctica on the containment sumps and delivering water to the suctions of the cenMf+1 charging pumps for makeup to the RCS.~ See Section 3,3 for a further discussic,n of the ECCE 28 1238
t Wolf Crcek -
,C 3.4.4 Svstem Success Criteria
- 1. The charging system can maintain pressurizer level at the normal operating level and pressure for an RCS equivalent pipe break opening up to 3/8 inch (0.375 in, liquid senice) or 3/4 inch -(0.75 in,- steam sen' ice) (Ref,1.
Section 9,3.4.2). The charging system is capable of making up for leakoff from such small breaks (up to approximately 120 gpm) with one centrifagal' 1, charging pump while still maintaining sealinjection flow to the reactor coolant pumps, ar.d allowing for a mimmum of reactor coolant contraction during cooldown. This is accomplished with the CVCS letdown line
- isolated (Ref.1, Section 9.3.4.3). i
- 2. Post shutdown boration of the reactor coolant can be accomplished with any
. one charging pump taking a suction on the RWST and injecting via any one of the following mdependent flow paths:
.the normal charging line via the regenerative heat exchanger to RCS-loops 1 and 4 the reactor coolani pump seal injection lines the boron injection tank to all four RCS cold legs. !

o l Wolf Creek \ 3.5 INSTRUMENTATION AND CONTROL (1 & C) SYSTEMS 3.5.1 System Function The instrumentation and control systems consist of the Reactor Protection System (RPS), the Engineered Safety Features Actuation System (ESFAS), and systems for the display of plant information to the operate:s. The RPS and ESFAS monitor the reactor plant, and alert the operator to take corrective action before specified limits are exceeded. The RPS will initiate an automatic reactor trip (scram) to rapidly shutdown the reactor when plant conditions exceed one or more specified limits. The ESFAS will automatically actuate selected safety systems based on the specific limits or combinations of - , limits that are exceeded. A remote shaidown capability is provided to ensu e that the reactor can be placed in a safe condition in the event that the main control room must be evacuated. 3.5.2 System Definition The.RPS includes sensor and transnutter units, logic units, and output trip - relays that operate reactor trip circuit breakers to cause a reactor scram. The ESFAS includes independent sensor and transmitter units, logic units and relays that interface with the control circuits for the many different sets of components titat can be actuated by the ESFAS. Operator instrumentation display systems consist of display anels in the control room and other locations that are powered by the 120 VAC electric power system (see Section 3.6). Instrumentation and controls for hot shutdown from outside the control room are located in the Auxiliary Building on the Auxiliary Shutdown Control Panels (ASDCPs). h v 3.5.3 System Ooeration A. RPS The Westinghouse RPS (or Reactor Trip System,. RTS) has two to four-redundant input instrument channels for each sensed parameter and two output actuation trains (A and B). The A and B logic trains mdependently generate a reactor trip command when prescribed parameters are outside the safe operating - range. Either RPS train is capable of opening a separate and independent reactor trip circuit breaker to cause a scram. The manual scram A and B circuits - bypass the RPS logic trains and send a reactor trip command directly_to shunt trip circuitry in the reactor trip circuit breakers. B. ESFAS The ESFAS -has three or four input instrument ektnnels for each ~ sensed parameter, and two output actuation trains-(A and B)J In general, each train controls equipment powered from different Class 1E AC electrical buses.- An individual component usually receives an actuation signal from only one ESFAS train. The ESFAS generates the following signals:--(1) reactor trip, provided one has not already been generated by the RPS, (2) safety injection - signal (SIS), (3) containment isolation, (4) main steam line isolation, (5) main feedwater line isolation, (6) emergency diesel start, (7) containment spray actuation, and (8) ventilation systems for the auxiliary building, control room, - and diesel building. The control room operators can manually trip the various ESFAS logic subsystems. Details regarding ESFAS -actuation logic are included in the system description for the actuated system. C. Remote Shutdown There are two distinct auxiliary shutdown panels; one panel is associated with instrumentation and control circuits used for controlling safe shutdown 34 12/88:
,1 j
i I WolfCreek i s equipment in Train A,'and the other panelis associated with instrumentation and control circuits used for controlling safe shutdown equipment in Train B. Both - panels are electrically separated and are associated wit:1 the same safety grade circuits that serve their respective trains; Train A control can be accomplished from either the auxiliary shutdown control panel or the control room without the use of a transfer switch; the equipment responds to the last signal from either location. Switches are provided on the Train B ASDCP to isolate and remove control from the control room for the Train B safe shutdown equipment necessary to take the plant to and maintain the alant in a safe hot shutdown condition independent of the control room. Not a 1 components on panel B can be isolated in this manner, Transfer of control to the Train B shutdown panel is alarmed in the control room. The electrical power that supplies al: of the devices controlled from these panels is avallaale following a loss of offsite - power. De controls on the auxiliary shutdown panels provide the capabilities _ ! of achieving and maintaining hot shutdown when the control room is - inaccessible. The controls provide a means of sustainin; the capabilities for boration, supplying steam generator feedwater and R TR, and. continuing ) reactor coolant pump seal injection and/or thermal barrier cooling water flow. # Cold shutdown conditions can also be met outside the cc'itrol room with some ; temporary instrumentation and control modifications, it should be noted that - for the AFW valves, only valve 5 is included in auxiliary shutdown-control-panel B. Controls available in the ASDCPs are identified in Table 3.51, 3.5,4 System Success criteria O A. RPS . The RPS uses hindrance logic (normal = 1, trip =;0) in both the input and output-- logic. Therefore, a channel will be in a trip state when input signals are lost, when control power is lost, or when the channel is temporarily removed from senice for testing or maintenance (i.e. the channel has a fail safe failure mode). A reactor scram will occur upon loss of control power tc, the RPS. A reactor scram usually is implemented by the scram circuit breakers which must open in response to'a scram signal. Typically, there are two series scram circuit breakers in the power path to the scram rods, . In this case, one of two circuit - breakers must open. Details of the scram system for Wolf Creek have not been determined. B. ESFAS '
- A single component usually receives a signal from only one ESFAS output train. ESFAS Trains A and B must be available Jn order to automatically actuate -
their respective components. ESFAS typically uses hindrance input logic (normal = 1, trip = 0) and transmission output. logic >(normal _= 0, trip = 1). In this case, an input channel will be in a trip state when input signals are lost, when control power is lost, or when the channel is temporarily removed from: F service for testing or maintenance (i.e. the channel has a fail safe failure mode).- Control power is needed for the ESFAS output channels to send an actuation signal. Note that there may be some ESFAS actuation subsystems that utilize hindrance output logic. For these subsystems, loss of control power will cause system or component actuation, as is the-case with the RPS. Details of the ESFAS system for Wolf Creek have not been determined. 1 C. Manuallv. Initiated Protective Actions When re'asonable time is available, certain protective actions may be performed-manually by plant personnel. The control room operators are capable of 35 12/88
-i
Wolf Creek O' operating individual components using normal control circuitry, or operating d groups of components by manually tripping the RPS or an ESFAS subsystem, The control room operators also may send qualified persons into the plant to operate components locally or from some other remote control location (i.e., the remote shutdown panel or a motor control center). To make these judgments,
, data on key plant parameters must be available to the operators.

w 3.6 ELECTRIC POWER SYSTEM 3.6.1 Svstem Function The electric power system supplies power to various equipment and systems needed for normal operation and/or response to accidents. The onsite Class 1E electric power system supports the operation of safety class systems and instrumentation needed to establish and maintain a safe shutdown plant condition following an accident or when the nomial electric power sources are not available. 3.6.2 Ssstem Definition The onsite Class lE electric power system consists of two AC load groups. Diesel generator A is connected to 4160 VAC bus NBCl, and diesel generator B is connected to 4160 VAC bus NB02. There are four emergency 480 VAC buses designated buses NG01, NG02, NG03, and NG04. Buses NG01 and NG03 are connected to bus NB01 throuch transfomlers XNG01 and XNG03. Buses NG02 and NG04 are connected to bus NB05 through transformers XNG02 and XNG04, 480 VAC motor control centers NG01 A, NG01B, and NG0lT receive their power from bus NG01,480 VAC motor control centers NG02A, NG02B, and NG02T receive their power from bus NG02,480 VAC motor control centers NG03C, NG03D, and NG03T receive their power from bus NG03, and 480 VAC motor control centers NG04C, NG04D, and NG04T receive their power from bus NG04 Emergency power for vital instrumentation, control, and emergency lighting is supplied by four 125 VDC/120 VAC load groups. Four station batteries energize four DC distribution panels, designated NK01, NK02, NK03, and NK04. Four 120 VAC p l instrument panels (NN01, NN02, NNO3, and NN04) are supplied from the DC distribution panels through inverters, or, as a backup, from 480 VAC MCC NG01 A or (d MCC NG02A through transformers. Simplified one-line diagrams of the electric power system are shown in Figures 3.6-1 and 3.6-2. Simplified one line diagrams of the 125 VDC and 120 VAC electri: Power systems are shown in Figures 3.6 3 and 3.6-4. A summary of data on selected electric power system components is presented in Table 3.61, 3.6.3 System Ooeration l During normal operation, the Class 1E electric power system is supplied from two independent sources within the power block: 13.8 kV bus PA01 and bus PA02. The emergency sources of AC power are the diesel generato. . The transfer from the preferred power source to the diesel generators is accomplished automatically by opening the normal source :ircuit breakers and then reenergizing the Class 1E portion of the electric power system from the diesel generators. The DC power system normally is supplied through the battery chargers, with the batteries " floating" on the system, maintaining a full charge. Upon loss of AC power, the entire DC load draws from the batteries. The batteries are sized to supply power to design loads for up to 6 hours without recharging (Ref.1). The 120 VAC vital buses normally receive power from the DC buses through their respective inverters. Redundant safeguards equipment such as motor driven pumps and motor operated valves are supplied by different VAC buses. For the purpose of discussion, this equipment has been grouped into " load groups". Load group AC/A contains components powered either directly or indirectly from 4160 bus NB01. Load group AC/B contains components powered either directly or indirectly from 4160 bus NB02. Componems O Ny receiving DC power are assigned to load groups DC/1, DC/2, DC/3, or DC/4, based on the battery power source. 38 12/88

D Wolf Creek 3.7 COMPONENT COOLING WATER SYS'IEM (CCWS) J 3.7.I Svstem Function The CCWS provides cooling water to various plant components during normal operation, plant shutdown, and after an accident. This system is a closed loop intermedtate cooling system between the components being cooled and the Essential Service Wat:r System (ESWS). Separation is required to minimize the possible releas4: of radioactive material. The CCWS serves to renwve residuti and sensible heat from ihe RCS during plant shutdown by cooling the RHR heat exchangers. 3.7.2 Svstem Definition The Component Cooling Water System (CCWG) consists of two se aarate 100% capacity trains which serve engineered safety features. The CCWS also inc udes a loop which serves non-essential equipment and is common to both trains. The non-essential loop can be isolated from the essential 3 cops during accident ec,nditions. Each safety-related CCWS train hat two 100% capa:ity pumps, one heat exchLnger, one surge tank, and associated piping and valves. The CCWS heat exchangers transfer heat to the Essential Service Water System. The surge tanks accommodate expansion, contraction, and in-leakage of water. . Simplified drawings of tne CCW syttem are shown in Figures 33-1 and 3]C. [ A summary oi data on selected CCW components is presented in Table 3.71. 3.7.3 Svstem Ooeratin During nomial operation, one CCWS loop is in operation with one CCW pump supplying cooling water to the non-essentialloop and to any operating comoonents in the
' /G associated essential loop (i.e., spent fuel cooling heat exchanger or a centrifugal charging
() pump). Heat is transferred from the CCWS to the Essential Sr. nice Water Sistem (ESWS) w hi;h is being supplied from pumps in the Service Water System (SWS). Heat loads supported by the essential loops of the CCW system include the following: RHR heat exchangers Si containment spray and centrifugal charging pumps and RHR pumps Fuel p(x>l cooling heat exchauger Heat loads supported by the non essentialloop nf the CCW system include the Letdown heat exchanger Excess letdown heat exchanger Positive displacement charging pump Seal water heat exchanger Reactor coolant pumps Makeup from the demineralized water storage tank to the CCWS is provided automatically to maintain the levelin the respective surge tanks in the proper range. The Essential Service Water System is an emergency source of water for CCWS makeup. A radiation detection system is provided in each CCWS train to detect abnormally high radioactivity that would be indicative of inleakage from one of the components served by the CCWS. Following receipt of a Safety Injection Signal (SIS) or following a loss of (O
'--) offsite power, one CCWS pump in each loop is placed in operation.
During a normal plant cooldown, both CCWS loops are in operation since flow through both RHR heat exchangers is required. An additional CCWS pump is staned in 53 12/88 I _ mhm.

i Wolf Creek 3.8 ESSENTIAL SERVICE WATER SYSTEM (ESWS) 3.8.1 System Functit s The Essential Service Water System provides the heat transfer path from essential equipment and systems to the ultimate heat i!nk (a 6000 acre cooling lake). The system also serves as a bac kup water source for the .'.uxiliar>4cedwater System. 3.8.2 Svstem Definition The ESWS consists of two 100 mercent capacity independent trains. Each train includes one centrifugal ESWS pump, a se f cleaning strainer, a supply cross tle from the _ . Service Water System (SWS), supply headers to the various heat ioads and equipment served by the ESWS, return headers, and discharge paths to the SWS or to a cooling lake. There are no cross ties between the ESWS trains. ~ Simplified drawings of the ESWS are shown in Fi;ures 3.81 through 3.8 4 - A summary of data on selectec ESWS components is presented in Table 3.81. 3,8.3 System Oneration During normal operation, the ESWS pumps are not operating, however, heat loads in the two ESWS trains are supplied with cooling water via cross tic lines between the ESWS and the Service Water System (SWS). Equipment cooled by the ESWS includes the following: Diesel pencrators CCW heat exchangers Spent fuel pool cooling heat exchangers O - pump room coolers for the SI, RHR, CS, centrifugal charging, AFW, and CCW pumps Class 1E switchgear room coolers Control room air conditioners Containment fan cooler units
- penetration room coolers Air compressor after coolers The ESWS is the backup source of water for the AFW System (see Section 3.2). ESWS train A can supply the turbine driven AFW pump and motor driven pump A, while ESWS train B can supply the turbine driven AFW ? ump and motor-driven pump B, In addition, the ESWS is the source of emergency maceup for the CCW System (see Section 3.7) and the fuel pool cooling and cleanup system.
The ESWS pumps are automatically started and the ESWS is isolated from the - I SWS following a loss of offsite power, a Safety injection Signal (SIS), or an AFW pump - low suction pressure signal. The ESWS pumps draw water from the cooling lake to supply essennal heat loac;s. The ESWS discharge is returned back to the cooling!ake. A radiation detection system is provided in each ESWS train to detect high radioactivity that would be indicative ofinleakage from an interfacing system.' 3,8.4 System Success Criterin Either train of the ESWS is sufficient to maintaln' the plant at an extended hot - shutdown. The success criteria for each train is as followst Coolant from the pumphouse forebay must be available. O - The respective ESW pump must operate. Q - Piping and valves from the respective ESW pamp to the heat sources and ultimate heat sink must remain intact.

l Wolf Creek 3.9 POST. ACCIDENT llEAT REMOVAL SYSTEMS (pal!RS) 3.9.1 Ssstem Function
'ihe PAHRS is an integrated set of subsystems that 3rovide the functions of containment heat removal and containment aressure control foi owing a loss of coolant I accident. In conjunction with the ECCS, tie PAHRS completes the post LOCA heat l transfer path from the reactor core to the ultimate heat Link 1 l
3.9.2 Sutem Definitir,a The PAlIRS cont.sts of two separate subsystems (Ref.1): Containment Spray System (CSS) Containment Cooling System (CCS) l The CSS consists of two parallel redundant subsystems, each feeding one 360 l degree spray header. Each CSS subsystem consists of one vertical centrifugal pump drawing suction from the Refueling Water Storage Tank (RWST) or the containment sump. The CSS does not include heat exchangers for containment cooling. The CCS consists of four fan cooler units divided into two independent trains. This system transfers heat from the containment to the Essential Service Water System (ESWS). Simplified drawings of the Containment Spray System (CSS) are shown in Figures 3S 1 and 3.9 2. The interface between the Contalnment Cooling System (CCS) and the Essential Service Water System is shown in Section 3.8. A summary of data on selected PAllRS components is presented in Table 3.91. Q 3.9 3. Sutem Oncration Q Dunng normal operation, the CSS and CCS are in standby Following a LOCA the CSS is actuated by a two out of four containment high pressure sigual. Each CSS pump draws water from the RWST and delivers water to independent spray headers in the containment dome. The CSS pump suctions are automatically realigned to the respective containment sump when a low level in the RWST is reached. The system continues to operate in a recirculation mode to maintain containment sprays. The CCS is actuated about 45 seconds after the safety injection signal (SIS). The ESW system should already be operating when the CCS fans are started (see Section 3.83 3,9,4 Ssstem Success Criteria Both the CSS and CCS have sufficient cooling capacity to independently perfoim the containment heat removal function. The success criteria for the CSS and the CCS are as follows:
- 1. One of two containment spray pumps (1 A or IB) must operate for CSS success. In the injection mode the RWST is the water source, and in the recirculation mode, the res,ective containment sump is the water source.
- 2. Any two of four fan coo er units must cperate with heat removal by the ESWS for CCS success.

Wolf Creek
- 4. PLANT INFORM ATION t
4,1 SITE AND BUILDING
SUMMARY
The Wolf Creek plant is located in Coffey County, Kansas,28 miles cast southenst of Emporia, Kansas. The site contains one operating Westinghouse PWR. A general view of the Wolf Creek site and vicinity is shown in Figure 41 (from Ref.1) and a plot plan of the Wolf Creek nuclear generating station is shown in Figure 4 2. The Wolf Creek Power Block consists of the reactor building, auxiliary building, fuel builc.ing, radwaste building, turbine building, control building, communication corridor, diesel generator building, and transformer vaults. The containment structure is a reinforced concrete cylinder with a steelliner. This structure contains the reactor vessel, reactor coolant pumps, steam generators, and pressurizer. Access to the containment is via an equipment hatch or personnel airlocks. Tae auxiliary building, west of the reactor building, houses pumps' piping and valves for the AFWS, ECCS, CYCS. and CCWS. The fuel building, which ts south of the reactor building, contains the spent fuel pool and new fuel storope. The control building, located northwest of the reactor building, houses the control room, the upper and lower cable spreading rooms the majorit,v of the Class lE power distribution equipment (4160 VAC buses. 480 V AC buses. 480 \ AC motor control centers,125 VDC distribution p nels, the 120 VAC instrumentation power panels, batteries). The diesel generator building, located west of the reactor buildin; and south of the control building, houses the emercency diesel generators and their auxiinry systems. The condensate storage tank which serves the AFWS is located nonheast of the reactor building. The refuelln; water storage tank which serves the ECCS ana the CVCS is located nonh of the radwaste suilding. The essential service water pumphouse is lceated to the west of the control building and houses the pumps, piping and
- O valves at the ESWS which cools emergency components and their respective working spaces.
4.2 FACILITY LAYOUT DRAWINGS Fi;ures 4 3 through 4 22 include section views and simplified t uilding layout drawings of tie Wolf Creek reactor building, diesel generator building. control building, fuel building. communications corridor, ESW pumphouse, and ESW valvehouse. Details of the turbine building and many of the outlying buildings are not shown on these drawings. Major stairways, elevators, and doorway: are shown, Labels printed in uppercase correspond to the location codes listed in Table 41 and used in the component data listing in Section 3. Some additional labels are included for information and are printed in lower case type. A listing of components by location is presented in Table 4 2. Components included in Tab:: 4 2 are those found in the system data tables in Section 3, therefore this table is only a partial listing of the components and equipment that are lccated in a particular room or area of the plant. 4.3 SECTION 4 REFERENCES

Wolf Creek APPENDIX A DEFINITION OF SYMilOLS USED IN Tile SYSTEM AND LAYOUT DRAWINGS A 1. SYSTEM DRAWINGS A 1.1 Fluid System Drawings The simplified system drawings are accurate representations of the majo'r now paths in a system and the important interfaces with other fluid systems. As a general rule, small Guid lines that are not essential to the basic operation of the system are not shown in these drawings. Lines of this type include instrumentation lines, vent lines, drain lines, and other lines that are less than 1/3 the diameter of the connecting major flow path. There usually are tw o versions of each Duid system drawing; a simplified system drawing, and a comparable drawing showing component locations. The drawing conventions used in the Guid system drawings are the following: Flow generally is left to right. Water sources are located on the left and water " users" (i.e., heat loads) or discharge paths are located on the right. One exception is the return flow path in closed loop systems which is right to left. Another exception is the Reactor Coolant System (RCS) drawing which is
" vessel centered", with the primary loops on both side; of the vessel.
Horizontal lines always dominate and break vertical lines. ^1 ( - Component symbols used in the fluid system drawings are defined in Figure A 1. Most valve and distinguish amon] pump
;, similar symbolsbased components are designed a allow on their support the reader to system requirements (i.e., electric power for a motor or solenoid, steam to drive a turbine. pneumatic or hydraulic source for valve operation, etc.)
Valve symbols allow the reader to distinguish among valves that allow flow in either direction, check (non return) valves, and valves that perform an overpressure protection function. Ne attempt has been made to define the , specific type of valve (i.e., as a globe, gate, butterfly, or other specine type of valve). Pump symbols distinguish between cenairugal and positive displacement pumps and between types of pump drivts (i.e., motor, turbine, or engine). Locations are identined in terms of plant loct tion codes defined in Section 4 of this Sourcebook. Location is indicated by shaded " zones that are not intended to represent the actual room geometry. Locations of discrete components represent the actual physical location of the component. Piping locations between discrete components represent the plant areas. through which the piping passes (i.e. including pipe tunnels and underground pipe runs). (p) Component locations that are n
- known are indicated by placing the components in an unshaded (white) zone.
V - The primary flow path in the system is highlighted (i.e., bold white line) in the location version of the Guid system drawings. I14 12/88

A1.2 Electrical System Drawings The electric power system drawings focus on the Class IE portions of the plant's electric 3cwer system. Separate drawings are provided for the AC and DC portions of the Class 13 system. There often are two vers ons of each electrical system drawingt a simplified system drawing, and a comparable drawing showing component locations. The drawing conventions used in the electncal system drawings are the following: Flow penerally is top to bottom In the AC power drawings, the interface with the switchyard and/or offsite
; rid is shown at the top of the drawing.
- n the DC power drawings, the betteries and the interface with the AC power system are shown at the top of the drawing.
Vertical lines dominate and break horizontal lines. Component symbols used in the electrical system drawings are defined in Figure A 2. Locations are identified in terms or plant location codes defined in Section 4 of this Sourcebod. Locations are indicated by shaded " zones" that are not intended to reoresent the actual room geometry. Locations of discrete components represent the actual physical location of the component. The electrical connections (i.e., cable runs) between discrete components, ,O ' as shown on the electrical system drawings, DO NOT represent the actual cable routing in the plant. Component locations that are not known are indicated by placing the discrete components in an unshaded (white) zone. A 2. SITE AND LAYOUT DRAWINGS , A 2.1 Site Drawir.gs A p .eral view of each reactor site and vicinity is presented along with a simplified site plan snowing the arrangement of the major buildings, tanks, and other features of the site. The general view of the reactor site is obtained from ORNL NSIC 55 (Ref,1). The site drawings are ap 3roximately to scale, but should not be used to estimate distances on the site. As built sea e drawings should be consulted for this purpose. Labels printed in bold uppercase correspond to the location codes defined in Section 4 and used in the component data listings and system drawings in Section 3. Some additional labels are included for information and are printed in lowercase type. A2.2 Layout Drawh:gs Simplified building layout drawings are developed for the portions of the plant that contain components and s./ stems that are described in Section 3 of this Sourcebook. > Generally, the following buildings are included: reactor building, auxiliary building, fuel building, diesel building, and the intake structure or pumphouse. Liyout drawings generally are not develored for other buildings. O Symbols used ir. the simplified layout drawings are defined in Figure A 3. Major Q rooms, stairways, clevatois, and doorways are shown in the sim fied layout drawings however, many interior walle have been omitted for clarity. The b ilding layout drawings, 115 12/88
Wolf Creek are approximately to scale, should not be used to estimate room size or distances. As-built scale drawings for should be consulted his purpose. Labels printed in uppercase bolded also correspond to the location codes defined in Section 4 and used in the component data listings and system drawings in Section 3. Some aditional labels are included for infonnation and are pnnted in lowercase type. A3. APPENDIN A ItEFERENCES

System codes used in this Sourcebook are the folle Co9 Definition RCS Reactor Coolant System FW Auxiliary Feedwater System 11P liigh pressure injection System (part of the Emergency Core Cooling System) CS Containment Spray LP Electric Power System AC Auxiliary Coolant Component Cochng Water System RW Raw Water System VA Containment Air Cooling System COMPONENT ID (also LOAD COMPONENT ID) - The component identi0 ration (!D) code in a data table matches the component ID that appears in the corresponding system (9 ( ,) drawing. The component ID generally begins with a system preface followed by a component number. The system prefacc is not necessarily the same as the system code described above. For component ids, the system preface corresponds to what the plant calls the component (e.g. HPI, RHR). An example is HPI 730, denoting valve number 730 in the high pressure injection system, which is part of the ECCS, The component number is a contraction of the component number appearing in the plant piping and instrumentation drawings (P&lDs) and electrical one line system drawings. LOCATION (also COMPONENT LOCATION and POWER SOURCE LOCATION) - Refer to the location codes defined in Section 4. COMPONENT TYPE (COMP TYPE) Refer to Table B 1 for alist of component type codes. POWER SOURCE The component ID of the power source is listed in this field (see COMPONENT ID, ateve), in this data base, a " power source" for a particular component (i.e. a load or a distribution component) is the next higher electrical distribution or , generating component in a distribution system. A single component may have more than one power source (i.e. a DC bus powered from a battery and a battery charger). POWER SOURCE VOLTAGE (also VOLTAGE) The voltage "seen" by a loarl of a power source is entered in this field. The downstream (output) voltage of a transformer, mverter, or battery charger is used.
