SCENARIO
SUMMARY
Length:
60 minutes The scenario begins with the plant operating at rated power. RHR System "A" is out of service for maintenance. An Inboard Drywell to Suppression Chamber Vacuum Breaker is inoperable (open). The crew will perform a planned transfer of RPS "A" electrical power supplies. During the transfer, a single control rod will scram due to a blown fuse on RPS "B" scram pilot valve solenoid. The crew will enter N2-SOP-08 for the unexpected power change and reduce generator MW electric. The crew will restore the control rod to the fully withdrawn position.
When conditions have stabilized, the Rams Head for a Jet Pump pair will separate. The crew will diagnose the jet pump failure based on plant parameter changes. Tech Specs will be entered and a required plant shutdown will be initiated.
During the power reduction, a malfunction in the EHC pressure regulator system causes a rapid reduction in reactor pressure. The crew will enter N2-SOP-23 and manually scram the reactor and close the MSIVs to stabilize reactor pressure and execute N2-EOP-RPV.
After reactor level and pressure are stabilized, the second vacuum breaker in the pair of Drywell to Suppression Chamber Vacuum Breakers will fail open concurrent with small leak from the Reactor Coolant System piping. The vacuum breaker failure results in a loss of Pressure Suppression function within the Primary Containment. As Drywell pressure slowly rises, the crew will execute N2-EOP-PC to control reactor vessel and primary containment parameters. After initiating containment sprays using RHR System "B", the ECCS suction strainer will gradually become clogged with debris in the Suppression Pool. Strainer plugging will require the crew to use an alternate source of containment spray, such as the Service Water System cross-tie to RHR System "B" in order to prevent exceeding Pressure Suppression Pressure Limit (PSP). The use of Service Water for containment spray will be successful in mitigating further degradation of the primary containment.

SUMMARY
Length:
60 minutes The scenario begins at 50% power during power ascension. The crew will continue the plant startup using normal operating procedures. Heater Drain Pumps will be lined up to pump forward prior to raising power.
The operating Control Rod Drive Pump will trip due to an electrical fault. The crew will implement the required actions of N2-SOP-30 and start the standby Control Rod Drive Pump. The crew will commence power ascension by raising Recirculation 'Flow System (RCS). As power is being raised, the RCS Flow Control Valve will experience a failure of the valve position components (RVDT) which results in an uncontrolled ramping open of the FCV. The operator will implement the actions of N2-SOP-08 to stop the valve motion by tripping the Hydraulic Power Unit (HPU). The power excursion results in a small amount of fuel failure, which results in elevated radiation levels later in the scenario. Tech Spec entry is required due to the RCS Loop Flow mismatch.
When conditions are stable, the circuit breaker for RCIC Steam Line Isolation valve trips open. This results in Primary Containment Isolation Valve inoperability. The crew will investigate the breaker trip. A steam leak will develop on the RCIC steam piping resulting in a rise in Reactor Building temperatures.
When the high temperature isolation setpoint is exceeded the crew will enter and execute N2-EOP-SC. A failure in the RCIC isolation circuit prevents manual and automatic isolation of the leaking steam line.
The crew will be required to manually initiate a reactor scram, based on the rising Reactor Building temperature. A group of 12 control rods will fail to fully insert. The crew will continue attempts to isolate the steam line and monitor the rising temperatures and radiation levels in the Reactor Building.
When more than one area temperature exceeds 212 0F, the crew is required to perform an RPV Blowdown per N2-EOP-C2. The Blowdown is complicated by the post scram control rod positions and the inability to open all seven ADS valves.

SUMMARY
Length:
75 minutes The crew will perform a scheduled surveillance on Standby Gas Train "B". APRM #2 will fail upscale, requiring bypassing of the failed instrument. After APRM#2 is bypassed, the Standby Gas Fan I B will trip. The SRO will enter Tech Specs for the inoperable GTS Train.
A report from the Turbine Building that Feedwater Pump "B" seal leak is worsening will prompt the crew to perform a Rapid Power Reduction by inserting Cram Rods and reducing Recirc Flow. Cram rod insertion is required because MFLCPR is above 0.93. Following the power reduction, the crew will perform an Emergency Shutdown of Feedwater Pump "B".
When conditions are stable, RCIC spuriously initiates. The crew will be required to stop RCIC injection within 4 minutes to prevent an automatic trip of the Main Turbine. For this scenario, if the crew does not stop RCIC injection in time, the RCIC turbine will automatically trip. This will ensure the remainder of the scenario runs as intended for candidate evaluations. When RCIC injection is stopped, a Loss of Offsite Line 5 occurs and the Division 1 Emergency Diesel Generator fails to start. This results in a required manual scram.
Following the manual scram, NPS-SWGOOI fails to transfer to Line 6. A loss of all Feedwater pumps results due to the degraded electrical sources. The crew will be required to control reactor water level with the High Pressure Core Spray (CSH) Pump. The CSH Pump will require a manual start to maintain level above TAF, due to a failure of the pump to automatically start. A small LOCA occurs resulting in a loss of inventory and the need for Drywell Spray.
After High Pressure Core Spray (CSH) injection is initiated, the High Pressure Core Spray (CSH) Pump will trip on an electrical fault. This results in a loss of all High Pressure Injection. The Crew will determine that RPV level cannot be maintained above TAF and execute the Alternate Level Control steps of N2-EOP-RPV. The Crew will then restore and maintain level above TAF by performing an RPV Blowdown and injecting with a Low Pressure Injection source.

SCENARIO
SUMMARY
Length:
90 minutes The scenario begins at rated power and Standby Liquid Control Pump "A" out of service. The crew will swap operating Service Water Pumps (SWP). When SWP*P1E is started, Feedwater flow transmitter "B" begins to intermittently fail, due to an air bound transmitter. The crew will respond by taking manual control of the Feedwater Level Control System (FWLC) and stabilizing water level in the normal operating band, per N2-SOP-06. While continuing with the SWP pump swap, the crew will dispatch assistance to determine the cause of the FWLC malfunction. After receiving a report from the field that the transmitter has been repaired, the crew will place FWLC back to automatic control. When FWLC is returned to automatic, an upscale failure of the Recirc Flow signal to APRM#2 will fail upscale, resulting in a control rod block. The crew will bypass APRM#2.
After FWLC is returned to automatic, a small increase in Condenser air in-leakage occurs and Condenser vacuum slowly degrades. The crew will perform a power reduction to stabilize vacuum per N2-SOP-09.
The reduction in power will stabilize condenser vacuum. While plant conditions are stable, the recently started SWP pump will trip, requiring Tech Spec entry. After starting an additional SWP pump to restore Tech Spec compliance, vacuum will again begin to lower and the crew will initiate a manual scram, prior to the automatic turbine low vacuum trip. Control rod pattern after the scram will result in reactor power remaining about 20%. The crew will enter and execute the Failure To Scram, N2-EOP-C5.
Condenser vacuum will continue to degrade, resulting in an automatic closure of the MSIVs. The crew will then control reactor pressure using the Relief Valves and start RHR in Suppression Pool Cooling. to control the heat addition into the Primary Containment. The Service Water Valve from the RHR Heat Exchanger will fail to open causing the crew to use the other available RHR loop for Suppression Pool Cooling. The crew will be required to manually inject boron and insert control rods to limit the Suppression Pool temperature rise.

After receiving a report from the field that the transmitter has been repaired, the crew will place FWLC back to automatic control.
After FWLC is returned to automatic, a small increase in Condenser air in-leakage occurs and Condenser vacuum slowly degrades. The crew will perform a power reduction to stabilize vacuum per N2-SOP-09. The reduction in power will stabilize condenser vacuum. While plant conditions are stable, the recently started SWP pump will trip, requiring Tech Spec entry. After starting an additional SWP pump to restore Tech Spec compliance, vacuum will again begin to lower and the crew will initiate a manual scram, prior to the automatic turbine low vacuum trip.
Control rod pattern after the scram will result in reactor power remaining about 20%. The crew will enter and execute the Failure To Scram, N2-EOP-C5.
Condenser vacuum will continue to degrade, resulting in an automatic closure of the MSIVs. The crew will then control reactor pressure using the Relief Valves and start RHR in Suppression Pool Cooling. to control the heat addition into the Primary Containment. The Service Water Valve from the RHR Heat Exchanger will fail to open causing the crew to use the other available RHR loop for Suppression Pool Cooling. The crew will be required to manually inject boron and insert control rods to limit the Suppression Pool temperature rise.
