75% Rated Thermal Power, EOL, following valve testing last shift. Crew will begin raising power to 100% power following shift turnover The scenario starts with a trip of 11 component cooling pump, after the crew verifies no common mode failure 12 component cooling pump is started IAW AOP-7C. This will resume CC flow to all components.
LCO 3.7.5 should be entered due to both 12 & 13 CC pps's aligned to 14 480V bus. After switching the power supply for 13 CC pp the LCO can be exited. A loss of 22 125V DC bus occurs which will cause multiple alarms. The crew will implement AOP-7J for loss of the DC bus. The crew will de-energize ESFAS Channel ZG, AFAS Channel ZG, RPS Channel D. 11B RCP will trip due to a locked rotor, this will cause numerous alarms.
The crew should check RPS calling for a trip due to multiple alarms.
Once crew identifies that reactor should have tripped CRS will order a reactor trip.
The manual pushbuttons will not work causing the crew to perform alternate actions of de- energizing the CEDM MG sets. When the reactor trips one set of turbine valves will fail to go shut causing an overcooling of the RCS. Failure of SGIS to shut MSIV's will require the CRO to manually shut them. The crew should recognize the SGIS failure and hold Tcold constant at current temperature using ADV's. After completing EOP-0 the CRS will implement EOP-8 due to the loss of 22 DC bus. VA-1 will not be met in EOP-8 and CRO should immediately begin worlung that safety function causing the RO to assess the rest of the safety functions. After all safety functions are assessed the RO should be assigned PIC4 due to Pressure and Inventory Control not being met in EOP-0. The scenario ends when VA-1 is completed by CRO and he is assigned HR-2.

Scenario starts with Pressurizer level transmitter X instrument failinmg low.
After identification of instrument failure channel Y level controller will be placed in service and PZR heater cutout selected to Y only (vice WY). Common tap analysis should be consulted and other instruments checked to ensure no instrument line leak.
CEA 37 in Group 5 will drop completely causing multiple alarms.
CRS will implement AOP-lB, with CRO lowering turbine load to restore Tcold to program. CRS will also notify OWC of CEA drop to ensure E&C response.
When crew attempts to realign the CEA the outward motion relay will stick causing the CEA to continue withdrawing even after inholdout switch is released. CEDS will be placed in off stopping CEA motion. When crew realizes they cannot realign the CEA a power reduction to 70% power should be ordered. During the power reduction IAW OP-3 an RCS leak will begin in excess of 1 charging pump. AOP-2A will be implemented which will eventually lead to a reactor trip. After the trip the leak will increase in size to 200 gpm. EOP-5 will be entered after completing EOP-0. The crew will begin a cooldown and depressurization to minimize leakage, during this step the crew will be unable to block SIAS B. The scenario ends when the crew has throttled safety injection flow to prevent overfilling the pressurizer. CRS will declare EAL H.A.5.1.2.

13 HPSI pump tagged out for repair Scenario starts with 12A RCP 1" stage seal failure.
The crew ensures only a single seal failed and notifies engineering.
Channel B RPS matrix power supply will fail causing multiple alarms at 1C05. After ensuring RPS is not calling for a trip the crew should enter LCO's 3.3.3.A
& 3.3.3.B. The CRS should call OWC to get I&C working on repairs to the power supply problem. After all LCO's determined calls made 12A RCP 3d stage seal will also fail. This second seal failure will require an expeditious shutdown IAW Alarm Manual. During the shutdown turbine valve CV-3 fails as is and turbine control becomes more difficult. The crew should recognize valve failure and implement AOP-7E. After crew stabilizes the plant a CIS B spurious actuation occurs which causes a loss of component cooling water to the RCP's. The crew will be unable to reset the CIS B and a reactor trip will be ordered. After verifying Reactivity control in EOP-0 the RCP's should be secured. After completing EOP-0 a transition to EOP-2 should occur. After a few steps are completed in EQP-2 a tube leak develops in 12 S/G causing the crew to transition to EQP-6. The scenario will end when the 12 S/G is isolated IAW EQP-6. CRS will declare EAL H.A.5.1.2 INSTRUCTOR SCENARIO INFORMATION

After crew takes the watch a NI channel A power summer amp fails causing multiple alarms. Once crew identifies failed power summer amp NO-1-200 should be referenced and LCO's 3.3.1.A & 3.3.1.D should be entered. CRO will bypass channel A trip units 1,2,7,8,10. A failure of the 12 S/G Main FRV controller will cause the FRV to fail to the D/P controller in manual. AOP-3G should be implemented. After verifying a good setpoint signal the CRO will commence auto operation with the Main Feed Bypass valve. Once feedwater is in auto a loss of offsite power will occur concurrent with a fault on the 11 4KV bus. This will cause a loss of all A train components. During EOP-0 the CRO will need to start 12 CC pp to prevent a RCS leak from the RCP seals. During the wrap up brief for EOP-0 the 11 AFW pump will trip causing a loss of all feedwater. CRS should implement EOP-3.
During EOP-3 the crew will cool down the primary using available S/G inventory and commence once through core cooling when S/G level reaches
-350". CRS should direct tying MCC 114 to MCC 104 to maximize PORV flow. Scenario ends when crew has determined OTCC will be successful IAW EOP Attachments.
CRS will declare Alert based on either A.A.7.1.2 or H.A.5.1.2
