A. INCORRECT: total HPI flow is less than 750 gpm (635) but the flow from the "C" HPIP
is less than 170 gpm. Encl 5.12 closed the HPIP minimum recirc valves (completion of
enc1.5.37) so the pump must have at least 170 gpm flow.
8. INCORRECT: flow is limited to less than 750 gpm total HPI flow with only one LPI/HPI
header operable when suction is from the RBES. The 30 gpm flow that shows on RCS Makeup
flow should not be indicated as HP-120 is closed (possible leak flow due to seismic damage)
C. INCORRECT: total HPI flow is 757 gpm (plus the 30 gpm possible damage flow)

A small break LOCA has occurred. Plant conditions are as follows:
- RCPs have been tripped due to a loss of subcooling margin.
- Primary to secondary heat transfer has been lost.
- RCPs are to be bumped.
Which one of the following is the advantage of bumping an RCP in the loop with the highest
hot leg level?
A.' to improve the chances of recoupling and establish natural circulation.
B. to allow more HPI flow to enter and refill the RCS.
C. to increase RCS pressure and allow RCS level to recover.
D. to reduce of the water hammer induced in the RCS piping and establish natural circulation.
Oconee Lesson Plan OP-OC-EAP-E22, pg 20 Obj. R14 based on 1992/01/20 bank question
A. Correct Answer
B. Incorrect. This will increase pressure and decrease HPI flow
C. Incorrect. RC Pump bumps are no longer used to collapse voids due to the reactivity
concerns associated with sweeping the voids through the core.
D. While this will help establish natural circulation, water hammer is not the reason for the
bumping.

A Unit shutdown was performed following a sudden pressurizer level drop.
LPI Cooler Outlet temperature = 175" F.
RCS Low Range Cooldown pressure = 250 psig.
Pressurizer level = 120 inches.
All RCP's are off.
NO outstanding prior Technical Specification CONDITIONS at this time.
Investigations indicate that the level drop may have been due to a pressurizer level instrument
malfunction. The OSM has requested that you consider the possibility of increasing
pressurizer level to 260 inches to facilitate trouble shooting the instrument.
Which one of the following is correct?
A. Pressurizer level can be increased to 260" with no additional requirements because the
B. Pressurizer level can be increased to 2 6 0 because an LTOP operator is already
established.
C.' Pressurizer level can be increased to 2 6 0 if an LTOP operator is established.
D. Technical Specifications will not allow pressurizer level > 220" at this time.
Answer 125

Following a station blackout, the crew enters AP/I/A/I 700/11. Shortly after entry in to
AP/1/A/l700/11 the Turbine Bypass Valves cycle on and off. Which one of the follow has
caused this to occur?
A. Condenser Hotwell Level cycling at the High setpoint.
B.' Low CCW flow as a result of gravity flow only
C. Main Steam Relief Valves unable to relieve OTSG Pressure.
D. Oscillating RCS Pressure and Natural Circulation due to cycling of the PORV.
Solution - B
Low gravity flow caused by the loss of valve position and control of the CCW system which
results in a lowering of condenser vacuum, which has in turn caused the Turbine Bypass
Valves to cycle on and off.
Reference -
Following a station blackout AP/I/A/1700/11 informs the operator that the Turbine Bypass
Valves may cycle on and off at the 7 inch Hg condenser vacuum low limit. Low CCW flow as a

A.' CX transformer.
B. either the 1X or 2X 600V transformer.
C. the 1X 600V transformer only.
D. the 2X 600V Transformer only.
solution - a
this is the normal alignment
B. Emergency Power
1. With the AUTO/MANUAL Transfer switch associated with ACBs 5 &7/6 & 8 in AUTO,
the auxiliary switchgears are in a normal power alignment. The Normal Power alignment being
determined by the position of the Underground breaker. If the underground breaker is
CLOSED, then the Normal power is from CX transformer. If the underground breaker is OPEN,
then the Normal power is from the units respective 600V transformer (either 1X or 2X). During
a loss of power to a unit's 600V switchgear, a 6 second timer starts. If power is restored to the
Normal source within this 6 seconds, the timer resets and no breaker action occurs. When the
6 second timer times out, the Normal power supply breaker OPENS and a 30 second timer
starts. If power comes back to the Normal source during this 30 seconds, then the normal
breaker will CLOSE back in. If the 30 second timer times out, and there is power available on
the Alternate source, then the alternate breaker will close in. This breaker stays closed until
manually opened, unless this Alternate source loses power and the Normal source has
regained power. If this occurs, the alternate breaker opens after a six (6) second timer times
out. If this occurs and there is power available on the Normal source, then the normal breaker
closes in immediately. If all of these actions have occurred and the unit is back on its Normal
power source, then the timers are all reset and the transfer scheme is ready to begin again.
2. With the transfer switch in MAN, no automatic transfers will occur. If power is lost to
either units 600V Auxiliary LC, manual action must be taken by the operator to restore power
per AP/O/A/2000/002, Keowee Hydro Station - Emergency Start.
If power is not restored to the 600V switchgears 1X &/or2X, then two independent sets of
batteries will supply control power to operate the units. Operation in this mode is limited to " 1
hour.

GO TO Step 13.
A. If RCS is saturated, Rule #2 will be performed as a higher priority. Rule #2 will perform
the same actions as steps 10 through 13 below for HPI flow verification. Therefore the RNO
skips HPI verification.
E. If RCS is subcooled, HPI verification will be performed here.
1.2 Ensure the following are open:
RNO:
(OBJ R10) IF both BWST suction valves
(1HP-24 and 1HP-25) are closed,
THEN perform the following:
A. Ensure the following are open:
ILP-15
E. Start 1A or 1B LPI Pump.
C. Dispatch an operator to open 1HP?363 (Letdown Line To LPI Pump Suction Block)
(Unit 1 LPI Hatch area).
The steps above will align LPI system discharge to the HPI pump suction.
Suction can be supplied to the HPI Pumps through ILP-15 and ILP-16 after passing through
the LPI Coolers. This flowpath would involve the LPI Pumps taking suction from the BWST..

Unit 1 is operating at 91% power when the OATC inadvertently places the S/D Bypass Key
switch to "Bypass"? Which one of the following will occur?
A. The Unit will continue to operate at 91%. However, the low pressure trip, the variable low
pressure trip, the flux/flow - imbalance trip, and the power/RCPs trip normally associated
with the RPS will be bypassed.
B. The Unit will run back to 74%. The low pressure trip, the variable low pressure trip, the
flux/flow - imbalance trip, and the power/RCPs trip normally associated with the RPS will be
bypassed.
C.' The unit will trip on high reactor pressure.
D. At 75% power, the bypass interlock switch is bypassed.
Solution C
In addition to bypassing the four trip parameters above, the "Bypass" position automatically
inserts a high RCS pressure trip set point of 1720 psig, so that the plant cannot be operated
normally with portions of the RPS in SID Bypass.
A. Protective Functions Bypasses
1. (OBJ R5) Shutdown Bypass
a) Certain segments of the RPS protective functions for a channel can be bypassed with a
key-switch located in that channel's RPS cabinet (A2, 82, C2, or D2). (OC-IC-RPS-8)
b) (OBJ R5.1) Bypass function is to provide capability to perform CRD testing, zero power
physics testing, and startup procedures. It provides the capability to reset the CRD breakers
when the plant is shut down. (Pull Group 1 to 50%).
c) (OBJ R5.2) During startup the RCS pressure is low and only one or two RCPs, at times,
are operating. This would keep RPS tripped.
(OBJ R5.2)
a) Positioning S/D Bypass Key switch to "Bypass" bypasses the Low Pressure Trip, the
variable low pressure trip, the flux/flow - imbalance trip, and the power/RCPs trip normally
associated with the RPS.
b) In addition to bypassing the four trip parameters above, the "Bypass" position
automatically inserts a high RCS pressure trip set point of f1720 psig, so that the plant cannot
be operated normally with portions of the RPS in S/D Bypass.
1) While the normal high pressure trip of E2355 psig is not electrically bypassed it is
basically nonfunctional because RPS will trip before the setpoint can be reached.
The setpoint of f1720 psig is selected for the new high pressure trip so that the plant must first
be shutdown, using normal procedures, before S/D Bypass can be initiated; 1720 psig is below
the normal low pressure trip of 1800 psig, so that the plant must first be maneuvered past the
normal low pressure trip point before going to S/D bypass. 1710 psig is the actual setpoint used
for conservatism.

A LOCA concurrent with a loss of some control board indications has occurred on Unit 2. The
STA calculates the RCS and containment pressure. He reports that RCS pressure 100 psia
-
and containment pressure 20 psia. The STA also notes that RB spray has not actuated.
-
Which one of the following describes the actions that should be taken and the basis for this
decision?
A,' No action should be taken, this is below the ES setpoint for RBS.
6. RBS should be actuated, this is below the actuation pressure assumed in the UFSAR.
C. RBS should be actuated, this is above the actuation pressure assumed in the UFSAR.
D. This is above the actuation pressure assumed in the UFSAR. Containment should be
vented, then the RES should be initiated.
The UFSAR assumes that RBS is actuated at 30 psig. The actual ES setpoint is 10 psig. The
20-psi difference between the safety analysis assumption and the plant setpoint is ample to
account for instrument uncertainty.
The purpose of the Reactor Building Spray initiation is to protect the Reactor Building by
removing heat from the RB via the LPI system decay heat coolers.
In addition, the RES system can help provide protection while not actually removing heat from
the RB.
The RBS system can be configured in many different ways while being used. The RBS can be
aligned to spray cool water from the BWST into the RB atmosphere. As the spray condenses
steam in the RB, the energy formerly in the steam is transferred to the liquid entering the RB
sump. The water in the sump is not cooled until the LPI system is realigned to pass water
through the LPI decay heat coolers. Current station procedures allow the water from the sump
to be sprayed back into the RB without being cooled. As with the injection mode of operation,
this mode will condense steam but will not remove heat from the RB. However, the
condensation of steam by the spray will work to decrease the internal pressure of the RB by
reducing the partial pressure of the steam. In this manner, the RB spray will help protect the
RB integrity without actually providing RB cooling.
The UFSAR assumes that RBS is actuated at 30 psig. The actual ES setpoint is 10 psig. The
20-psi difference between the safety analysis assumption and the plant setpoint is ample to
account for instrument uncertainty.
The UFSAR states that a 2.4-second ESFAS delay is assumed for Reactor Building Spray
actuation.
T. S. basis for the 4 psi and 15 psi setpoints is to establish a setting which would be reached
immediately in the event of a DBA, cover the entire spectrum of break sizes, and yet be far
enough above normal operation pressures to prevent spurious initiation.

functions:
Removes sensible and latent heat from the containment atmosphere.
Operation of the RBS System also serves to entrain fission product iodine (released into the RB

(MS-153 & 154 "A" line and MS-155 & 156 on " B line). Due to the difficulty in operating these
valves (caused by the large DP), additional piping and valves were added on each unit.
A 1" bypass line now exists around MS-153 & MS-155. A 1" gate valve installed in each
bypass line allows for reducing the DP across these 12" gate valves which allows for ease of
operation.
Another line which bypasses MS-154 and MS-156 has a chain operated "drag" valve installed.
These drag valves are much easier to operate and are suited better for throttling. Many turns
of the handwheel are required for stroking these valves which will provide for a more controlled
cooldown in the event they are needed.

Which one of the following describe the system that Oconee uses to prevent water hammers
from occurring in an "idle" steam line.
All steam lines in the plant have small drain lines that side of the isolation
valve.
A. automatically open on the downstream
B." automatically open on the upstream
C. are operated manually on the downstream
D. are operated manually on the upstream
I I
A. Steam Traps (OBJ R14, 15)
1. An "idle" steam line (one in which there is no flow due to a closed isolation valve) tends
to collect condensation in the line where the steam is bottled up.
2. All steam lines in the plant have small drain lines on the upstream side of the isolation
valve in the line, to keep the condensation from building up.
3. These small drain lines automatically drain condensate to the condenser to prevent the
steam line from filling with water andlor to prevent water hammers from occurring. This is
accomplished by the use of a steam trap.
Thermostatic steam traps at Oconee are basically a valve with an expandable bellows acting as
a valve disk.

Valve 1V-I96 (CSAE Exhaust to Stack Drain) must be locked closed at all times if activity
above background exists on the OTSG secondary side.
Which one of the following is the reason for this action?
A,' This prevents the release of radioactive liquid to the trench.
B. This prevents the CSAE relief valve from cycling.
C . This prevents the condenser from being isolated on high activity.
D. This maintains high backpressure on CSAE.
A. (0BJ.RG)Valve (1)(2)(3) V-196 (CSAE Exhaust to Stack Drain) must be locked closed at
all times if activity above background exists on the OTSG secondary side. (This prevents the
release of radioactive liquid to the trench.)
In May of 1999, Unit 3 3C CSAE relief valve began lifting and closing several times. The steam
supply was isolated hoping the relief valve would reseat. As a result, air entered through the
relief valve and entered the condenser causing U3 to begin losing vacuum. Power was
reduced per the AP to 73%, 3C CSAE was fully isolated and the Main Vacuum Pumps were
placed in service
Faulty Air Removal
a) High condensate temperature to the CSAE will cause a reduction in air ejector
efficiency.
b) Low steam pressure or clogged steam strainers will reduce the velocity of steam and
thus reduce the volume of air the CSAE will handle.
c) High backpressure on CSAE will affect air removal.
d)
Loss of loop seal would "short cycle" the air back into the system.

B. To prevent feedwater pump cavitation.
C. To allow complete closure of the minimum flow valves before reaching 100% power.

Wednesday, May 07,2003 01:39:25 PM 70

Automatic ICs demand signals to the Main and Startup Control Valves are developed from a
common signal source called the Valve Composite Demand
1) Power increase: At a composite demand of 9.0% (equivalent to 90% open on the SU
Control Valve), a bistable will automatically open the Main FDW Block Valve (if in AUTO).
1. Main Blocks (FDW-31 and FDW-40)
a) Motor operated from control room (UBI).
b) OPEN, AUTO, CLOSE.
c) ICs sends a signal to close the Main FDW Blocks on a Rx trip.
d) Automatic ICs demand signals to the Main and Startup Control Valves are developed
from a common signal source called the Valve Composite Demand
1) Power increase: At a composite demand of 9.0% (equivalent to 90% open on the SU
Control Valve), a bistable will automatically open the Main FDW Block Valve (if in AUTO).
2) Power decrease: At a composite demand of 5.0%, the Main FDW Block Valve will close
(if in AUTO)
e) During some unit startups, when the Main Blocks were opened, leakage past the seat of
the closed Main Control Valves would cause SG levels to increase. This would result in the SU
Control Valves, which are controlling SG levels to start close and return SG levels to setpoint
(25 inches SUR).
1) With the Main Blocks in AUTO, as the SU Control Valves reached 50%, the Main Blocks
would close. After they closed, leakage past the seat of the Main Control Valves would stop,
and SG levels would decrease, causing the SU Control Valves to re-open.
2) As the SU Control Valve reaches 90%, the Main Block would once again open, setting
up a Feedwater cycle that could quickly become divergent. Once divergent cycle starts, a
FDWP trip could occur due to Overspeed or High Discharge Pressure if not properly mitigated.
This would lead to a UnitlReactor Trip.
3) To prevent the Feedwater swing described above, the Main Block Valves were placed in
OPEN when the Startup Control Valves reached 90%, and were left in OPEN until Feedwater
demand was high enough to ensure that the SU Control Valves would not close. Current
procedures require that the Main Blocks (and SU Blocks) be in AUTO prior to exceeding 700
psig MS pressure (to satisfy MSLB/AFIS circuit operability requirements).
Procedures do allow FDW-31 and 40 to be placed in OPEN if FDW control problems occur as a
result of the valves opening in AUTO. The blocks will then be placed in AUTO when the Main
Control Valve has reached 10% OPEN, since at that point, the SU Control Valve demand is at
loo%, and is not likely to decrease until power level decreases for unit shutdown.
2) Power decrease: At a composite demand of 5.0%, the Main FDW Block Valve will close
(if in AUTO)
d) Automatic ICs demand signals to the Main and Startup Control Valves are developed
from a common signal source called the Valve Composite Demand
1) Power increase: At a composite demand of 9.0% (equivalent to 90% open on the SU
Control Valve), a bistable will automatically open the Main FDW Block Valve (if in AUTO).
2) Power decrease: At a composite demand of 5.0%, the Main FDW Block Valve will close
(if in AUTO)

SG pressure is 1000 psig. The TDEFWP is running. A controller failure has caused FDW-315
& 316 to fail full open.
Which one of the following indications would enable the OATC to determine that this failure
had occured?
The crew would:
A. see a flow mismatch on Total EFDW Flow indications but would NOT see it on the
MDEFDWP Discharge Flow gages.
B.' NOT see a flow mismatch on Total EFDW Flow indications but would see it on the
MDEFDWP Discharge Flow gages.
C. see a mismatch between the indicated flows to each SG. This indicated flow mismatch
could be as much as 300 gpm
D. NOT see a flow mismatch on Total EFDW Flow indications but would see a level change
between the OTSGs because the SG are level dominant.
EFW lesson plan
1. The MDEFDWPs have approximately 300 gpm (per pump) recirculation flow to the UST
for pump and discharge piping protection. When a MDEFDWP is started, the ARC (Automatic
Recirculation Control) valve automatically provides recirculation flow.
NOTE: An event has occurred at another plant concerning these same type ARC valves. The
valves failed open due to internal valve failure. One of the problems that came from this failure
was the operators were not able to determine from their flow indications that these valves had
failed. Some examples of what the Oconee operator might see if these MDEFDWP
recirculation valves failed open follows:
The initial assumption is that the TDEFDWP is not running.
If SG pressures were at about 1000 psig and the A MDEFDWP recirculation valve failed
open, there would be a mismatch between the indicated flows to each SG. This indicated flow
mismatch could be as much as 300 gpm if FDW-315 & 316 were full open. The operator would
see the flow mismatch and depending on decay.heat could see a lower SG level on the side
with the failed valve. There would not be a pump runout concern unless SG pressures were
800 psig or less and FDW-315 & 316 were full open.
If the TDEFDWP were running, the operator would NOT see a flow mismatch on Total
EFDW Flow indications but would see it on the MDEFDWP Discharge Flow gages.
If the operator sees a flow mismatch or low SG level and the TDEFDWP is available, he should
start the TDEFDWP. Starting the TDEFDWP will assure adequate flow to the SGs

Which one of the following is the reason that the interim building gas tanks should not be used
as the "in service gas tank?
A. There is no way to recirc interim building gas tank contents.
B. There is no way to align the interim building gas tank to reduce the hydrogen concentration.
C. The only release path is direct to atmosphere.
D.' The interim building gas tank requires about 20 psi Nitrogen pressure to have control of
vent header pressure.
Solution - D
B. Tank Isolation
1. Tank should be isolated prior to high pressure alarm (70 psig).
2. Interim building gas tanks should not be used as the "in service" gas tank since it
initially requires about 20 psi Nitrogen pressure to have control of vent header pressure.
3. Basic procedure:
a) Tank should be > 5 psig prior to placing in service, add Nitrogen if required to increase
tank pressure.
b) Close "recirc" valve for isolated tank and open "recirc" valve for tank placed in service.
c) Close inlet valve for tank to be isolated and open inlet to tank to be placed in service.
d) Sample isolated tank for hydrogen.
e) After tank has been isolated for 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, verify that isolated tank pressure is not
decreasing and vent header is controlling normally.
4. Reducing Hydrogen in a GWD Tank
a) If hydrogen is > 3%, lower tank to 50 psig by transferring some for the gas to another
tank.
b) Add 20 psig nitrogen to tank
c) Resample for hydrogen
d) Repeat until hydrogen < 3%
C. Transferring Gas Between Tanks
1. Normally done from in-service tank to another tank, this adds operational flexibility to
determine which tank is used for in-service work and which tank(s) are used for isolation and
decay.
2. Procedure:
a) Open inlet for tank receiving gas
b) Close inlet for tank transferring gas.
1) In-service tank pressure should begin decreasing and tank receiving gas should be
increasing pressure as gas flows:
From the in-service GWD Tank
Through GWD-1
To the vent header
Wedngsday, May 07,2003 01:39:26PM .. 81
Is compressed by GWD compressor
Discharges to tank being transferred to
c) When transfer is complete, open inlet for tank remaining in service and close inlet for
tank to be isolated.
d) Sample isolated tank for hydrogen.
D. Sampling of waste gas decay tank
1. Sampling is done
a) 5 times weekly and after isolation for hydrogen
b) Prior to release for activity
2. Sample flowpath: (sample flows from tank, through sample apparatus, to the vent
E. (Obj R5) Cross-connecting the vent header
1. Isolation valves GWD-132 (Vent Header Tie Unit 1) and GWD-134 (Vent Header Tie
Unit 3) are opened to make essentially one common vent header.
2. Either system (1&2's) or (3's) can be shutdown.
3. The other system can carry the load.
F. Gaseous Waste Releases
1. Should only be made when:
a) Additional tank space is needed.
b) Acceptable meteorological conditions exist as indicated on OAC.
1) Unfavorable conditions are:
(a) Positive delta temperature
(b) Very low wind speed
2) Sign Off step for Meteorological conditions are in the body of the procedure. Part of the
process of deciding to submit a sample request for release should involve anticipating
Meteorological conditions that will exist at time of desired release.
3) Atmospheric inversions
(a) The use of vertical temperature gradients is a practical and universally accepted method
of determining atmospheric stability. An inversion is defined as: air at ground level colder than
air aloft. Simply stated, unusually stable atmospheric conditions exist when an inversion exists,
meaning that vertical air movement is stifled. Clear, calm nighttime conditions are usually very
stable because the earth's surface cools rapidly, thus cooling the ground surface air. This is
usually the time of day that an inversion will exist. The absence of winds prevents this cool air
from "mixing" with the warmer air above. It is under these unfavorable, stable atmospheric
conditions that the release of radioactive gases would not be desired.
2. We should hold tanks as long as possible to allow maximum radioactive decay (ALARA)
and therefore release as little activity as practicable.
3. Prior to release, the operator submits a sample request and RP samples the tank to
determine:
a) Types of activity
b) Quantities of each isotope present
4. RP also calculates and notes on sample request
a) Setpoints for RIA-37 & 38
b) Maximum allowable release flow rates
5. Procedure
Steps described are a general description of actual procedure steps. Refer to
procedure if more detail is desired.

1. INTRODUCTION
1.1 This lesson plan discusses the normal and abnormal operation of the plant in relation to
the Instrument Air and Service Air Systems. The major components in the systems,
components operated by compressed air and the effects on plant operations if these
components lose IA are discussed.
1.2
(Obj. R1)The purpose of the Instrument Air System is to supply a reliable source of clean, dry,
oil-free compressed air, at the proper pressure, to the numerous valves, controllers, and
instruments throughout the plant that operate on compressed air. The IA System is the normal
supply for instrument air to the Radwaste Facility.
1.3 Numerous controllers and instruments in the control room, and valves throughout the
plant, are designed to operate by means of compressed air. Controllers translate demand
signals to the devices by throttling the amount of compressed air reaching them. The amount of
throttling is determined by the operator at the control station, which can then be set to
automatically maintain the required supply. Some instruments operate on an air signal,
proportional to the value of the parameter being measured. Numerous valves throughout the
plant are positioned by either admitting compressed air to an operating cylinder, or by bleeding
air from the cylinder. 1.4 The IA System supplies the air pressure to operate these devices.
The Primary IA compressor normally maintains IA header pressure. The Backup IA
compressors normally serves as a backup to the Primary IA compressor.
1.5 A third set of Service Air compressors supply air for equipment such as air drills, paint
sprayers, air hoses and the sewage ejectors. Operating pressure is approximately that of the
Instrument Air System. There are two rotary screwtype Sullair compressors. It normally only
takes one compressor to meet the needs of the Service Air System. If required, these
compressors supply another backup source to supply Instrument Air loads.
A fourth source of air during emergency situations is from a diesel-driven air compressor that
can be aligned to the Station Air header and manually started to help supply total IA
requirements.

FDW is not yet restored, but RCS conditions do not yet require HPI cooling. Two RCPs are left
running to reduce total heat input to the RCS. The preferred configuration is one RCP per loop
so that forced flow exists in both SGs when feedwater is restored. Since it is not known in
which SG(s) feedwater will be restored, or if it will be restored, one RCP should be left running
in each loop if possible. The selection of RCPs to run should consider pressurizer spray flow
capacity.

Important Human Actions
The following are some important human actions from the Oconee PRA. More detailed
information can be found in the Oconee PRA Report Rev. 2, Chapter 3.
Event or Sequence Operator Action
Loss of all AC Power, TB Flood Activate the SSF
LOCA Establish recirc. from containment
Turbine Building Flood Refill the Elevated Water Storage Tank
Loss of 416OvAC during a tornado Connect HPI pump power to ASW
switchgear
Small or Medium LOCA Stop the LPI Pumps (Pumping Against
Shutoff Head)
TB Flood, Tornado (w/ BWST Failure) Swap HPI Suction to Spent Fuel Pool
Loss of All LPSW Cross-connect LPSW Header to other
Activate the SSF -Activation of the SSF is important for many types of events,
including: Seismic, Flood, and Station Blackouts (including Tornado and TB Fire).
-
Establish Recirculation From the Sump Swap to sump recirculation and
establishing high pressure recirculation are important to prevent ECCS failure following
a LOCA.
-
Refilling the Elevated Water Storage Tank Refilling the EWST is important
following a Turbine Building flood by providing backup cooling for the HPI pumps.
HPI to ASW Switchgear -Tornado damage to the 4160 V switchgear in the Turbine
Building can be mitigated by connecting an HPI pump to the ASW switchgear.
-
Throttling the LPI Pumps Throttling the LPI pumps is an important human action to
prevent pump failure from operating in run-out conditions following a large LOCA.
-
Stopping the LPI Pumps Stopping the LPI pumps for small and medium LOCA
sequences prevents pump damage from dead-heading against the high RCS
pressure.
Swap HPI Suction To The SFP - Depletion of the BWST inventory during a TB Flood
can be mitigated by realigning the HPI suction to the SFP. This can also be used in
Tornado Sequences which damage the BWST.
Cross-Connect LPSW To Another Unit - LPSW flow from another unit can be used to
cool important loads including such as the HPI motor coolers and the CC Coolers.
