-s Aux. Feedwater Pump Room Ventilation Systems The Auxiliary Feedwater Pump Room Ventilation Systems are shown on P&ID M-026A and KVAC plan drawing M-413.
The systems consist of one (1) 100% capacity, Q exhaust fan per pump room, fans C73-1 and 2, temperature switches TS-5135 and TS-5136, and motor-operated exhaust air dampets EV-4835 and HV-4836. Missile protection supply air transfer grills are located in the elevation 585' Turbine Building floor slab, and exhaust air is discharged frem each room through similar openings located so as to preclude short-circuiting of supply and exhaust air. Each exhaust fan is started automatically by its pump room temperature switch at a predetermined temperature setpoint and is sized to maintain its pump room between 60*F and 120*F during all modes of operation including post-accident, utilizing supply air from the Turbine Building at <110*F.
Loss of an Auxiliary Feedwater Pump Room Ventilation System will make the train inoperable. Due to the small size of the Auxiliary Feedwater Pump Rooms and the magnitude of the room heat loads, these rooms cannot be maintained indefinitely at or below 120*F following a failure of their respective ventilation systems, regardless of the ambient outside air temperature, nor can operability of the affected Auxiliary Feedwater train be ensured once the room temperature goes above 120*F.
In order to comply with the single failure criterion, redundancy is provided by the availability of the alternate train Auxiliary Feedwater System and its associated ventilation system.
i
.2 The 1-2 AFPT has a PGG type governor. Manual or Auto Essential speed change signals drive an internal speed changer motor. This I
change determines a new speed setpoint and the governor moves the steam governor valve to drive the turbine to the new speed. The l

PURPOSE The purpose of this procedure is to provide a procedure for operating the Aux *.liary Feedwater System (AFWS). The following modes of operation are covered.
MODES SECTION Placing the AFWS in service for plant startup 4.0 Removing the AFWS from service for plant shutdown 5.0 Manual and Abnormal Operations of the AFWS 6.0 AFWS Shutdown from Manual Operation o_r from SFRCS Initiation 7.0 i
DISCUSSION The purpose of the Auxiliary Feedwater System is. to provide feedwater to the SG's for the removal of decay heat in the absence of main feedwater and to promote natural circulation in the reactor coolant system on a loss of all four reactor coolant pumps.
During normal plant operation, the Auxiliary Feedwater System performs no function.
It is a standby system to be used should there be a loss of the Main Feedwater System or it is desired to promote natural
+s 22 circulation. The Auxiliary Feed Nozzles must be used to fill a dry
(.)
The Auxiliary Feedwater System consists of the following components:
two steam turbine-driven feedwater pumps (AFP), two condensate storage tanks (CST), suction and discharge water piping, steam piping, valves and associated instrumentation and controls.
Turbine Driven Feedwater Pumps:
The auxiliary feedwater pumps are horizontal, seven stage, double volute, centrifugal pumps having a capacity of 1050 spa at 1050 psig. The capacity of the AFP was determined by the decay heat removal requirements 40 seconds after a reactor trip from full power
- one AFP meets this capacity requirements.
The turbines can take steam from either the main or auxiliary steam system. Valves in the main steam system permit operating the auxiliary feed pump turbines from either their respective SG's or the opposite SG.
The auxiliary feed pumps can take a suction from either the 4
~
Condensate Storage Tanks, Service Water System, or the Fire Protection System. The pumps are capable of discharging the auxiliary feedwater either to its respective SG or the opposite SG through a set of isolation and cross-over valves discharging into the SG's through the auxiliary feedwater nozzles located at 596'-3 3/8" in reference to the SG Startup Range Indication.
i
2 SP 1106.06.22 q
The amount of feedwater entering the SG is controlled by varying the AFPT speed using the AFPT speed changer. The AFP head curve (Enclosure #1) and FI 4521, 4522, 4630 or 4631 must be used to prevent pump runout 32 when operating at various speeds and discharge /SG pressures. When using AFW with low stea, pressures, the AFP discharge pressure at LSS may be too great to properly control OTSG levels. At that time AF 360 and AF 388 will La closed and feedwater enters the SG through a 0.46" restricting orifice (RO-416 ana R0-498) which bypass the AFP discharge valve (s) AF-360 and/or AF-388.
The auxiliary feed pump turbines are rated at 800 hp at 3600 rps for a steam pressure of 885 psig and steam temperature of 590*F. The turbines are of the horizontal. type having a split casing, solid (helical) wheel rotor and two stages.
Overspeed protection for the auxiliary feedwater pump turbine is provided by a turbine trip throttle valve actuated by the mechanical overspeed tripping device on the turbine. Should the trip throttle valve trip on overspeed, an operator must be dispatched to the auxiliary feed pump to manually reset the val.ve since the valve is locally operated and no remor.e reset is provided. Overspeed trip occurs at approximately 4500 rpm.
22l The turbine governor has a low speed stop set at 1100 RPM.
The auxiliary feed pump turbine governor valve is operated hydraulically
.)}
by an oil pump attached to the turbine shaft. Hyoraulic oil pressure is not developed until the turbine is turning. Therefore, on a loss of oil pressure or until the oil pressure is developed, the governor valve position remains as is.
s During operation, a minimum speed of 600 RPM is required to circulate lube oil. Circulation of the AFP lubricating oil is accomplished by means of a " circulator" within the Kingbury thrust bearing. The pumping force is the adhesioa of the oil to the thrust collar rim.
Oil is drawn from the oil reservoir and enters the oil circulator.
The oil is carried around by a collar until-it encounters the closely fitting parts of the ring where it is scraped off into the oil passages, flowing along the shaft and then outward between the thrust shoes. The oil then travels through the oil cooler where it returns to the reservoir. Oil from the circulator also goes to the journal bearing at the other end of the pump shaft via supply and return piping. Both the built in journal bearing of the Kingsbury thrust unit and the separate journal bearing of the AFP's have an oil ring at one end of the bearing shell for lubrication. The pump bearing lubricating oil system is cooled by an oil reservoir oil cooler noused within the thrust bearing lower casing. Cooling water is normally supplied by the firsi stage discharge of the AFP.
Cooling water for the AFPT bearing oil is provided by the first stage discharge of the AFP (normally) or. from the service water system (alternate).

_s The AFPT's have two operational modes: Auto Essential and Manual, j
The mode selector switch still has an ICS position which is not to be used.
l The Auto Essential mode automatically controls Steam Generator level by controlling the AFPT speed. If an SFRCS trip occurs the Steam 22j Generator level will be controlled at 46 inches on the Startup Range.
If an SFRCS and an SFAS level 2 trip is present, the Steam Generator 22l level will be controlled at 124 inches on the startup range. HIS SP9B (HIS SP9A) is a high-low select switch which allows the operator to 22l select either the 124 inch (green) or 46 inch (red) setpoint. An SFAS level 2 trip will override the HIS and automatically select the 124 inch level setpoint. This SFAS signal can be blocked using HIS SP981 22l (HIS SP9A1) and the 46 inch setpoint can be reselected using HIS SP9B l
(HIS SP9A). If a less than 612 PSI SFRCS occurs, the opposite trains 22l AFP will feed the good OTSG to 50" or 128" if a level 2 SFAS occurs.
The other AFP is in standby at low speed stop. In the manual mode, 22l the operator through the use of the AFPT speed changer switch can either raise or lower AFPT speed to adjust SG level. When operating in this mode, use of the pump head curve (Enclosure 1) is mandatory mandatory to prevent pump runout.
The AFP TRBL annunciator will alarm due to the following four conditions.
If the Mode Selector switch is in any position other than auto-essential.
If the AFPT trip throttle valve is fully closed.
If steam pressure at the inlet of AFPT is less than 10 psig. If AFP suction pressure is less than 1 psig. The last two conditions should close the AFPT main steam valve.
The AFPT's exhaust through silencers to the atmosphere.
A sentinal valve on each AFPT casing is set at 28 psig to provide audible and visual warnings to the operator of excessive exhaust pressure. Local pressure gauges provide a means of measuring exhaust pressure.
Condensate Storage Tanks The condensate storage capacity is sized so that a total condensate inventory of 250,000 gallons may be available to the AFP's to remove decay heat for approximately 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> plus a subsequent cooldown of the plant to 280*F.
Instrumentation and Control There are 4 low pressure switches (2 for each AFP) located on the suction line from the CST which automatically switches the AFP suction to service water on the event-suction pressure from CST falls below 2 psig. If suction pressure from CST increases to above 2 psig this will enable the Operator to manually switch AFP suction from service water back to CST. There are 4' additional low pressure switches (2 for each AFP) on pump suction which automatically closes

FI 4521 and FI 4630 indicates the amount of Auxiliary Feedwater flow to Steam Generator 1 from either Auxiliary Feed Pump. FI 4522 and 4631 indicates the amount of Auxiliary Feedwater Flow to Steam Generator 2 from either Auxiliary Feed Pump. FI 4521 and FI 4522 are Ultrasonic Flow instruments. FI 4630 and FI 4631 are Safety grade orifice Type Flow instruments on the Post Accident Instrument Panel.
The remote control switches HIS-360 and HIS-388 (Figure 1) on control room console C-5709 for the AFP discharge valves AF 360 and AF 388 have a mechanical latching device built into the switch which engages l
and holds the "Open" pushbutton in the open position whenever it is pressed. Adjacent to the "Open" pushbutton is a smaller release pushbutton labeled "Off".
Depressing this pushbutton releases the mechanical latch function and permits closing of the valve.
Open Off Open Close (Red)

Close l
Figure 1 Located between the AFPT trip throttle valve and the AFPT steam isolation valve on each main steam line are four pressure switches.
The purpose of these pressure switches is to close the AFPT main steam isolation valves should a main steam line break occur between the AFP room and the isolation valves in the auxiliary building.
The pressure switches are set to close the AFPT main steam isolation-valves should steam pressure decrease to less than 10 psig. Once these pressure switches have tripped, their relay must be reset. To reset, an operator must be dispatched to press their reset pushbuttons which are' located at Auxiliary Building Elevation 585 by MCC E11C
-(for MS 106 and MS 106A) and #2 Electrical Penetration Roon by MCC Fila (for MS 107 and MS 107A). A time delay with a variable setpoint is part of the valve closure circuit. Once the main steam isolation valve has begun to open, 10 psig must be developed at these pressure switches within the alloted time span of the time delay, otherwise, the AFPT main steam isolation valves will close.
21]
Any condition which causes the AFWS to depart from its normal opera-tional status, whether it be due to an abnormal valve lineup, component failure, repair work or routine maintenance, requires the operator to turn on the " Manual System Bypass" indicating light (AFW 4800) using RS-4800 on the SFAS panel. The illumination of this blue light serves as a reminder and indication to the operator that the system is in an inoperable status.

2.6 Whenever the Auxiliary Feedwater System is inoperable because of a failure, repair work in progress, or routine maintenance on the system, the operator is to turn IL-4800 " AUX FW SYS" on using ES-4800 on SFAS Panel C-5717. This light is to remain on as long as the system is inoperable.
2.7 Steam traps are placed in operation as per Enclosure 2 and Valve Verification List "A".
'l 2.8 If a SFAS actuation occurs, the following requirements apply:
2.8.1 DO NOT OVERRIDE ANY SAFETY EQUIPMENT EXCEPT AS LISTED SELOW:
1.
IF PLANT CONDITIONS ARE STABLE AT NORMAL OPERATING OR HOT STANDBY CONDITIONS AFTER A TRANSIENT WITH NO EVIDENCE OF AN RCS LEAK, SYSTEMS MAY BE BYPASSED WITH THE SHIFT SUPERVISOR'S PERMISSION.
2.
IF THERE ARE ANY QUESTIONABLE C0hTITIONS OR ANY SIGN OF AN RCS LEAK, NO SAFETY SYSTEM SHOULD BE BYPASSED WITHOUT APPROVAL OF STATION MANAGEMENT 22 (PLANT MANAGER OR HIS DESIGNEE).
2.8.2 If an SFAS signal to some ESF equipment is " Blocked" (i.e. overridden), that equipment is incapable of responding to either any subsequent automatic actuation signal or the SFAS system-level manual, actuate
(" Trip") pushbuttons on Panel C5717. Before an operator " Blocks" any SEAS signal, he must assure that the safety function of the equipment is no longer needed. Af terward the operator is totally responsible for the proper operation of that equipment, including reactuation if required, until the " Block" is removed.

Reactuation, subsequent to a " Block", can be accomplished two ways. First, at the equipment level, " Blocked" equipment will respond to the individual control I
switches for that piece of equipment. Second at the SFAS system level, operation of the system-level
" Reset" pushbutton on Panel C5717 will clear any output logic blocks in the system (output logic
" Blocks" are the block switches next to the SAM lights 4
and on the output modules). The equipment will then i
respond to the system-level manual, actuate (" Trip")
pushbutton and to automatic actuation signals. For 1
guidance on resetting the SFAS after a real or erroneous 22 trip see EP 1202.01, RPS, SFAS, SFRCS Trip, or SG Tube Rupture.

(
maximum bearing metal temperature for the AFPT is 220*.
l 2.10 Maximum seal water temperature is 160*F and maximum seal tempera-ture is 300*F.
2.11 Four pressure switches (2 for each AFP) automatically shift AFP t'
suction to Service Water on low AFP suction pressure of 2 psig.
i If cooldown using AFP's is required for an extensive period such t
that CST water is exhausted, the automatic shift to Service 7 -
Water should be verified or manually initiated if CST level falls below 3 feet. Manual initiation is achieved by opening SW f
1382 (SV to AFP 1-1 suction) and SW 1383 (SW to AFP 1-2 suction) and then closing FW 786 (AFP 1-1 suction valve) and FW 790 (AFP 1-2 suction valve). This can be done from the Control Room using the Control Room seitches.

6.1.2 Energize and record AFPT and AFP data on speed and vibration monitors during startup.
6.2 Procedure 6.2.1 Determine the AFP(s) that will be used and from which source it will take a suction. Normal AFP suction is from the Condensate Storage Tanks (CST).
If suction is desired from one of the other water systems, the valve for the desired source must_be opened: for Service Water, SW-1382 and/or SW-1383; for Fire Protection Water FP-28 (these sources of water are not preferred due to water chemistry probless).
NOTE:
On low AFP suction from CST (2 psig pressure, 3 feet of water in CST's), suction will automatically shif t to Service Water.
If AFP suction pressure remains low the AFPT steam valves are blocked from opening.
22 6.2.2 Perform the following to drain the AFPT.
1.
Check open the following casing drains.
MS 745 (MS 744)
