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.

Unit 1 plant conditions:

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

PORV is operable.

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

REFERENCE ALLOWED - 1108101 LR CD curve and LTOP logic diagram

A. Incorrect. Although the PORV is operable, adrnin controls require pressurizer level <220"

unless an LTOP operator is established.

6. Incorrect. Since the unit is in NO Tech Spec conditions, an LTOP operator is not already

established.

C. Correct. An LTOP operator is allowed to replace any of the admin controls in Train 2 of

LTOP (see TS 3.4.12 bases).

D. Incorrect See above.

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

Voltage and current from the three phases of the RC Pump Switchgear feed a transducer. At

100% power, the output from this transducer results in an 18 millivolt signal. If this signal drops

to 25% below the 18 millivolts, a signal is sent to Reactor Protective System that the RC Pump

is tripped (there is one RC Pump Power Monitor for each of the 4 RCPs).

1.

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 &/or 2X, then two independent sets of

Which one of the following is correct concerning the current BWST level trend?

A. The constant BWST level trend is not expected and LPI pump(s)must be secured to

prevent overheating.

B. The constant BWST level trend is not expected and LPI pump(s)must be secured to

A.

Incorrect: suction is from the RBES, LPI pump operation may continue.

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

a)

b)

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.

Certain segments of the RPS protective functions for a channel can be bypassed with a

(OBJ R5.1) Bypass function is to provide capability to perform CRD testing, zero power

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.

Which one of the following describes the purpose of the Reactor Building Spray System?

A. Removes sensible AND latent heat from the containment atmosphere, entrains fission

product iodine and decreases radiation levels in containment.

B. Removes ONLY latent heat from the containment atmosphere, entrains fission product

iodine, and decreases radiation levels in containment.

C.' Removes sensible AND latent heat from the containment atmosphere and entrains fission

(decrease radiation levels in containment) is wrong. It may pull contaminants that give off

radiation out of the atmosphere, but it redeposits it in the sump.

(Obj R1)Purposes of the Reactor Building Spray (RBS) System

The Reactor Bldg. Spray system has no function during normal plant operation.

When actuated by high Reactor Building (RB) pressure, the system provides two major

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

during a LOCA) into the spray water, thereby reducing possible iodine leakage to the

environment (to meet IOCFRIOO criteria concerning offsite dose limits).

Just inside the 5th floor of the turbine building, a 12" line on each main steam line taps off and

on these lines?

These valves are designed to be used for a controlled plant cooldown in the event that the:

A. Atmospheric Dump Valves (ADVs) become inoperative. These valves are manually

controlled plant cooldown in the event that the Turbine Bypass Valves (TBVs) become

inoperative.

a)

ADVs are credited for reducing SG pressure and cooling the RCS when condenser

vacuum is lost during SGTR and SBLOCA event analysis

3.

Originally two manual gate isolation valves were installed on each atmospheric vent line

(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 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.

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.

Loss of loop seal would "short cycle" the air back into the system.

Which one of the following indications would enable the OATC to determine that this failure

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

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.

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 MDEFDWPs have approximately 300 gpm (per pump) recirculation flow to the UST

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.

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

If the TDEFDWP were running, the operator would NOT see a flow mismatch on Total

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)

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

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. Limits and Precautions

2.1 One SSW header is required to be operable for ESV to meet TS 3.7.8 (ECCW)

requirements. For the required SSW header to be operable, the required LPSW pumps to

that header must be operable (Ref SLC 16.9.12), AND LPSW Pump Auto Start on the

Unit supplying the operating SSW header must be operable (Ref TS 3.3.28).

2.2 Normal SSW lineup should be as follows:

• A SSW Header in service with LPSW (SSW-1) valved in; HPSW-901 throttled to

maintain balanced flow between A and B SSW Headers to within 20 gpm.. {I}

B SSW Header in service with LPSW (SSW-2) valved in, HPSW-900 closed.

• A and B SSW Headers supplying all CCW and ESV pumps.

• Maintain > 50 gpm in a single SSW Header, to allow surveillance of SSW

strainer .P. {I}

2.3 Entry into SLC 16.9.12 is NOT required IF SSW header flow < 50 gpm due to changes

in SSW header flow caused by startinglstopping ESV pumps, large changes in HPSW

pressure, etc Enclosure "Balancing Flow Between SSW Headers" can be performed as

needed.

1.1

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

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 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.

This lesson plan discusses the normal and abnormal operation of the plant in relation to

Numerous controllers and instruments in the control room, and valves throughout the

The IA System supplies the air pressure to operate these devices.

Unit 3 has implemented the inadequate heat transfer procedure due to a complete loss of

feedwater.

The crew has just completed Steps 9 and 10 which opened the RCS High Point Vents.

RCS pressure will be governed by which one of the following?

A. a combination of HPI pump discharge pressure, the high point vent flow capacity and the

decay heat level.

B. a combination of HPI pump discharge pressure, the PORV relief flow capacity, the high

point vent flow capacity and the decay heat level.

C.'

a combination of HPI pump discharge pressure, the PORV relief flow capacity and the

decay heat level.

D. HPI pump discharge pressure only.

Inadequate Heat transfer Lesson plan page 15

Steps 9 and 10 opens the RCS High Point Vents which will result in lower RCS pressure, which

will allow greater injection flow and therefore better core cooling.

RCS pressure will be governed by a combination of HPI pump discharge pressure, the PORV

relief flow capacity and the decay heat level.

The "Loss of Heat Transfer" Tab has been implemented when Unit 1 suffered a loss of Main

and Emergency Feedwater.

FDW is not yet restored, but RCS conditions do not yet require HPI cooling.

Which one of the following describe the preferred configuration of the RCPs?

A,' One RCP per loop

B. Any One RCP

C. 1Al RCP and any other RCP

D. All RCPs running

THEN GO TO Step 4.

RNO:

1.

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.

Further Explanation of C - while 1Al RCP provides the best PZR spray, the preferred

configuration is one pump per loop

(Obj. R2) Reduce operating RCPs to one pumplloop.

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

Loss of all AC Power, TB Flood

LOCA

Turbine Building Flood

Loss of 416OvAC during a tornado

Operator Action

Activate the SSF

Establish recirc. from containment

sump

Refill the Elevated Water Storage Tank

Connect HPI pump power to ASW

Large LOCA

Small or Medium LOCA

TB Flood, Tornado (w/ BWST Failure)

Loss of All LPSW

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.

A. Correct - When 2TA swgr lockout occurs the reactor will trip on flux1flow (loss of 2 RCPs)

this meet entry conditions to the EOP. APE9 should be stopped as the first note say AP129

should not be used when EOP entry conditions exist. This note is conflicting later in AP129

when tripping the reacfor per APE9 then the EOP is not entered.
