SIMULATOR EXAMINATION SCENARIO SUMMARY
SCENARIO NRC 1
The scenario starts with the unit at 45% power ready for a second Main Feed Water pump
to be started. The unit was returned to power last shift following feed train work and cleared a 30%
chemistry hold 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> ago. Rods are in manual due to a problem with auto rod control that I&C is
currently investigating. The letdown radiation monitor is OOS. The turbine-driven auxiliary
feedwater pump, I-FW-P-2, was tagged out during the chemistry hold and has just been returned to
service, PMT was SAT. 2-CC-P-IA is tagged out for seal work.
First, the crew will start a second Main Feed Pump in accordance with I-OP-2.I, "Unit
Startup from Mode 2 to Mode 1," and I-OP-3I.I, "Main Feedwater System."
Next, the crew will ramp the unit up in accordance with I-OP-2.I, "Unit Startup from Mode
2 to Mode 1." Once the reactor power has increased approximately 5%, the first failure will occur.
During the ramp, I-CN-P-IA will trip and I-CN-P-IB will not auto-start. The crew will
enter I-AP-3I, "Loss of Main Feedwater," and start the "B" Condensate pump. Several minutes
into the event, an IRPI for rod K-2 in control bank "A" will drop to zero. The US will review
technical specification 3.1.7 and notify the instrument shop. Once condensate flow has been re-
established and tech specs reviewed, the next event can occur.
At this time, charging flow transmitter, I-CH-FT-1122, will fail high. The crew will
respond in accordance with the AR for C-C5 and take manual control of I-CH-FCV-II22. Once
charging flow has been restored to normal the next event can occur.
Next, the Channel III steam pressure transmitter for "A" SG (I-MS-PT-I475) fails low.
The crew should enter I-AP-3, "Loss of Vital Instrumentation," swap steam generator level control
channels, and refer to technical specifications. At this time the next event can occur.
Due to the earlier oscillation on the charging system, a tube leak will develop in the non-
regenerative heat exchanger. The crew will respond in accordance with I-AP-I6, "Increasing
Primary Plant Leakage." The crew will isolate letdown and make preparations to place excess
letdown in service. At this time the next event can occur.
Asmall steam leak will develop in the main steam valve house on the "A" steam line
between the main steam trip valve and the containment wall. The crew will notice a decrease in
megawatts and an increase in reactor power and enter I-AP-38, "Excessive Load Increase," and
begin to ramp the unit down. At this time the next event can occur.
The "A" main steam line will rupture and the crew will be expected to enter I-E-O,
"Reactor Trip and Safety Injection." The reactor will fail to trip, requiring the crew to transition
to FR-S.I, "Response to Nuclear Power GenerationJATWS." Rods will not be able to be inserted
in auto. Once the reactor has tripped the crew will return to I-E-O and then transition to I-E-2,
"Faulted Steam Generator Isolation." The crew will then transition to I-ES-I.I, "SI
Termination." The scenario may be ended once SI has been terminated, or at the discretion of the
lead evaluator.

neither of these transients (blowdown of a single SG with or without RCPs running)
constitutes an orange-path challenge to the integrity CSF. However, if the faulted SG is not
isolated, the cooldown transient for reactor vessel inlet temperature could result in an
orange-path challenge to the integrity CSF, especially if RCPs are not running.

SIMULATOR EXAMINATION SCENARIO SUMMARY
SCENARIO NRC 2
The scenario begins with the unit at 100% power. The letdown radiation monitor is OOS
and the terry turbine was returned to service last shift. 2-CC-P-IA is tagged out for seal
maintenance.
After the crew assumes the watch, the unit 2 "A" service water pump will trip resulting in a
loss of service water to "B" header. The crew should respond in accordance with I-AP-I2, "Loss of
Service Water," and after checking system integrity, start the unit 1 "B" SW pump. After the
service water system has been verified stable, the next event will occur.
The next event will be a failure of the automatic rod control system. Control rods will start
inserting for no known reason. The crew will be expected to perform the immediate operator
actions of AP-I.I, "Continuous Uncontrolled Rod Motion," and place rod control in manual. After
the crew stabilizes the unit and directs I&C department to investigate, the next event will occur.
The crew should identify an increase in Main Condenser pressure and enter I-AP-I4, "Low
Condenser Vacuum," to respond to the event. As directed by I-AP-I4, the crew should reduce
main turbine load until main condenser vacuum stabilizes. During the ramp the "A" MFRV will
lose its level error signal. Due to this failure the valve will not automatically control level at
program during transient conditions. When sent to investigate the vacuum loss, the turbine building
operator will report that the "A" Air Ejector loop seal is hot to the touch. He will be directed to
isolate the loop seal. Once this has been done, vacuum will start to improve and the crew will stop
the ramp. When the unit is stable the next event can occur.
Next, the running charging pump, I-CH-P-IA, will degrade. The crew will start another
charging pump. When the crew secures the degraded pump its discharge check valve will stick
open. The crew should enter I-AP-49, "Loss ofNormal Charging." The crew will close the "A"
charging pump discharge and restore charging to normal. The crew will then use AP-49 to
reestablish letdown and stabilize the plant. The Unit Supervisor should refer to Technical
Specifications and declare the "A" charging pump inoperable. Due to "C" pump having no auto-
start capability, and thus only being operable when running, the crew will make preparations to start
this pump. At this point the next event will occur.
The transient on the charging system will cause an RCS leak to occur inside the
containment. The crew should respond in accordance with I-AP-I6, "Increasing Primary Plant
Leakage." The US should refer to Technical Specifications and either direct the crew to commence
a unit shutdown or make preparations for a containment entry due to excessive RCS leakage. Once
the crew has commenced either a ramp or started preparations for a containment entry, the next
event will occur.
The RCS leak will worsen and the crew will trip the reactor and enter I-E-O, "Reactor Trip
or Safety Injection." Safety injection will fail to actuate automatically, but can be manually
initiated. The BIT inlet valves will fail to open automatically and will have to be manually opened.
The crew will stop the RCPs and close the charging pump recirc valves. The crew will transition
to I-E-I, "Loss of Reactor or Secondary Coolant." Once the crew has performed some actions in I-
E-I, the scenario can be terminated.

SIMULATOR EXAMINATION SCENARIO SUMMARY
SCENARIO NRC 2
The scenario begins with the unit at 100% power. The letdown radiation monitor is OOS
and the terry turbine was returned to service last shift. 2-CC-P-IA is tagged out for seal
maintenance.
The "A" bearing cooling pump, I-BC-P-IA, will trip. The crew should identifY the loss of
bearing cooling and respond in accordance with l-AP-19, "Loss of Bearing Cooling Water." The
crew should determine that the "B" bearing cooling pump did not automatically start, and per the
RNO start I-BC-P-IB. Once the crew has verified that the BC System has been restored, or as
directed by the Lead Evaluator, the next event will occur.
The next event will be the failure of the median/select Tave unit. The crew will be
expected to respond lAW l-AP-l.l, "Continuous Uncontrolled Rod Motion," and place rod
control in MANUAL. Crew should address annunciator response for B-A7, MEDIANIHI TAVG
< > TREF DEVIATION, and take manual control of charging flow, and place steam dumps in
steam pressure mode. After these actions have been completed and plant conditions are stable, or
as directed by the lead evaluator, the next event will occur.
A loss of instrument air will occur when 2-IA-C-l trips. The crew will enter l-AP-28,
"Loss of Instrument Air," and start all available air compressors. (l-IA-C-l will not start
automatically, but will start in HAND). Once instrument air pressure is returned to normal, the next
event will occur.
Next, PRZR level transmitter, l-RC-LT-1461, will fail low. The crew will respond to the
failed channel IAW l-AP-3,"Loss of Vital Instrumentation." The crew will swap to an operable
level channel, restore letdown (Normal event), and review Tech Specs.
The next failure to occur will be the "B" SG PORV failing open due to the failure of the
E/P. The crew will reduce power per l-AP-38, "Excessive Load Increase." They will restore
reactor power to less than 100% and dispatch an operator to fmd the cause of the power increase,
close the valve locally, and stabilize the unit. The next event will occur after the crew has
stabilized the unit, or at the direction of the lead evaluator.
Shortly after the unit is stablized, I-FW-P-IA will trip due to low oil pressure. The BOP
must identifY the pump trip, recognize that "B" MFP did not automatically start and take actions
IAW l-AP-31, "Loss of Main Feedwater." The crew will trip the reactor in accordance with the
immediate actions of l-AP-31 and enter l-E-O, "Reactor Trip or Safety Injection." The next event
will take place on the reactor trip.
The reactor will not automatically trip, if required, and as a result of the transient placed
on the main feedwater system, a feed line break will occur on the main feed pump suction line
resulting in a loss of all main feed pumps. Several minutes after the reactor is tripped, I-FW-P-2
will trip on overspeed and will not be able to be immediately reset. Since a safety injection will
not be required at this time, the crew will transition to l-ES-O.l, "Reactor Trip Response." Once
SXG NRC 3 Page 3 Revision 0
the crew transitions to 1-ES-0.1, "Reactor Trip Response," the last event will occur.
"A" MDAFW pump discharge line will break in the MSVH and no flow will reach the
SG. The "B" MDAFW pump will degrade due to impeller damage. The crew should identify the
loss of all feedwater and transition to 1-FR-H.1, "Response to Loss of Secondary Heat Sink." On
their first pass through 1-FR-H.1, the crew will not be able to restore main feed, auxiliary feed, or
condensate flow to the steam generators. At this point, 1-FW-P-2 will be reset and the crew
should establish adequate auxiliary feedwater flow to the SGs, allowing them to transition out of
1-FR-H.1. The scenario may be terminated after transition, or at the direction of the lead
evaluator.

SIMULATOR EXAMINATION SCENARIO SUMMARY
SCENARIO NRC 2
Scenario begins with the unit at approximately 22% power with a power increase held for
turnover. Unit was returned to service last shift after an outage to repair a leak on the EHC
interface valve. The terry turbine was tagged out during the outage and has just been returned to
service. The letdown radiation monitor is OOS. 2-CC-P-IA is tagged out for seal maintenance.
Shift orders are to ramp to 100%. Control rods are in manual while the instrument shop verifies
proper operation due to a previous problem.
The crew will increase reactor power in accordance with 1-0P-2.1, "Unit Startup from
Mode 2 to Mode 1."
Once a satisfactory power increases has been seen, the running EHC pump will trip with a
failure of the standby pump to auto-start. The crew will start the standby pump per AR for T-B4 or
US direction. At this time the crew will be informed that control rods can be placed in AUTO.
Once the standby pump is running the next event can occur.
The PRZR master pressure controller will fail causing 1-RC-PCV-1455C and both spray
valves to open. The US should direct the crew to enter 1-AP-44, "Loss ofRCS Pressure." The RO
will manually close 1-RC-PCV-1455C and use the master pressure controller to close the spray
valves. Once the crew has stabilized RCS pressure and consulted Tech Specs, or at the direction of
the lead evaluator, the next event will occur.
Channel ill level transmitter for the "B" steam generator will fail low. The crew should
identify this failure and take manual control of the "B" main feed reg. valve to restore level in the
"B" SG. The crew should enter 1-AP-3, "Loss of Vital Instrumentation," and refer to technical
specifications to determine operability of the transmitter. Once the crew has identified the
applicable MOP and referred to Tech Specs, the next event will occur.
Next, Nuclear Instrument channel N-44 will fail high causing the control rods to drive in at
maximum speed. The RO must identify N-44 as failing and place rod control in MANUAL. The
crew will enter 1-AP-4.3, "Malfunction of Nuclear Instrumentation (power Range)," and place N-
44 in trip (Normal event). The US/STA should review Technical Specification 3.3.1. After N-44
has been placed in trip, the next event will occur.
A tube leak will occur on "B" SG. The first indication will be the N-16 radiation monitor
for "B" SG indicating increased leakage. The US should direct the crew to enter 1-AP-5, "Unit 1
Radiation Monitoring System," and direct HP/Chemistry to obtain and analyze a "B" SG blowdown
sample. Eventually, the main steamline header N-16 monitor indication will increase and the crew
will have backup indication of a tube leak in the "B" SG. Based on confIrmed leakage, the US
should direct the crew to enter 1-AP-24, "Steam Generator Tube Leak." The tube leakage will
increase until a reactor trip is necessary. The crew will enter 1-E-0, "Reactor Trip or Safety
Injection."
The turbine will not trip automatically and must be tripped using pushbuttons. Following a
transition to ES-O.l, "Reactor Trip Response," a SGTR will develop in the "B" steam generator.
SXG NRC 4 Page 3 Revision 0
Following identification of degrading primary plant conditions the crew will manually safety inject
and transition back to E-O, "Reactor Trip or Safety Injection." The crew will proceed through E-O
and transition to and perform E-3, "Steam Generator Tube Rupture." During this time the "A" RCP
will develop a seal failure and the crew will need to secure it and close the sealleakoff valve per 1-
AP-33.1, "Reactor Coolant Pump Seal Failure." The crew will cooldown the RCS using E-3. At
this time the scenario can be terminated.

SIMULATOR EXAMINATION SCENARIO SUMMARY
SCENARIO NRC 2
The scenario begins with the unit at 100% power. The letdown radiation monitor is OOS
and the terry turbine was returned to service last shift. 2-CC-P-1A is tagged out for seal
maintenance.
VCT Level transmitter 112 will fail high. The crew will respond in accordance with the AR
for VCT HI-LO LEVEL L-112, by placing 1-CH-LCV-1115A in manual and raising the output to
100% to stop diverting to the stripper. The crew should discuss the loss of the RWST swapover
on low level. Once the crew has stopped the VCT divert the next event can occur.
The high-level divert for the "A" HP heater drain tank will fail open. The "A" HP heater
drain pump will trip. The "B" Condensate pump will not start in auto, if required. Power will
increase due to the colder water entering the SGs. The crew will enter 1-AP-31, "Loss of Main
Feedwater," and start the standby Condensate pump along with 1-AP-38, "Excessive Load
Increase," to ramp the unit down slightly to reduce power to less than 100%. Rods will not step in
auto if required and will have to be operated in manual. An operator will report that the controller
was found to be loose, and level can be restored to within the normal band. The next event will
occur once the crew has stabilized the unit and restored the high-level divert.
The "A" pressurizer spray valve will fail open. The crew will enter 1-AP-44, "Loss of
Reactor Coolant System Pressure," and the RO will be required to use the remote close SOV in
order to close the spray valve. Once the crew has stabilized RCS pressure, the next event can
occur.
The main generator voltage regulator will fail and the crew will be expected to respond in
accordance with 1-AP-26, "Loss of Main Generator Voltage ControL" The BOP will turn off the
voltage regulator and control voltage using base adjust. After generator voltage has been brought
under control, the next event will occur.
A loss of 1H bus will occur. Due to a fault on the bus the 1H EDG output breaker will not
close to reenergize the bus. This will result in the High-Level Divert Valves failing open and a loss
of CC to the RCP thermal barriers. The crew will need to enter 1-AP-38, "Excessive Load
Increase," and ramp the unit to reduce reactor power. Reminder: Rods will not step in auto. As
time permits, the crew will enter 0-AP-10, "Loss of Electrical Power," to diagnose the power loss.
The crew will eventually be informed that the electricians will need a tagout in order to examine the
bus for damage. Once reactor power has been reduced to the previous power level, the next event
can occur.
A loss of the switchyard will occur as a result of problem on the grid. The 1J EDG will not
start in automatic. The crew will enter 1-ECA-0.0, "Loss of All AC," and will be able to restore the
11 bus using the attachment. They will be able to transition to 1-E-0, "Reactor Trip or Safety
Injection," and then to 1-ES-0.1, "Reactor Trip Response." At this time the 1H bus will be restored.
Once the crew has stabilized the unit and reenergized 1H bus, a leak will develop in the
Safeguards area. The crew will transition back to 1-E-0 and eventually to 1-ECA-1.2, "LOCA
Outside Containment," where they will isolate the leak. At this time the scenario can be terminated.

Safety Significance'
Failure to close the RCS spray valve under the postulated plant conditions constitutes
"mis-operation or incorrect crew performance which leads to degradation of any barrier to
fission product release." In this case, DNBR is reduced. Therefore, failure to close the
spray valve represents a "demonstrated inability by the crew to take an action or
combination of actions that would prevent a challenge to plant safety."

CT Statement*
Crew restores power to any AC Emergency bus.
Safety Significance'
Failure to energize an ac emergency bus constitutes "mis-operation or incorrect crew
performance which leads to degraded...emergency power capacity." Failure to perform the
critical task also results in needless degradation of a barrier to fission product release,
specifically of the RCS barrier at the point of the RCP seals. Additionally, failure to
perform the critical task results in the unnecessary continuation of a situation in which RCS
inventory is being lost uncontrollably and cannot be replaced. This situation is equivalent to
"mis-operation or incorrect crew performance which leads to degraded ECCS...capacity" at
a time when a small-break LOCA is in progress.

Safety Significance'
Failure to isolate a LOCA outside containment (that can be isolated) degrades containment
integrity beyond the level of degradation irreparably by the postulated conditions. It also
constitutes a "mis-operation or incorrect crew performance which leads to degradation of a
barrier to fission product release" and eventually "to degraded ECCS capacity.
