1L21N1 After taking the shift at 55% power with directions to maintain power, MOL, Leak Collection Exhaust fan, 1VS-F-4A, will trip, the crew will respond using the ARP which will direct the BOP to manually start 1VS-F-4B. The SRO will address applicable TS and License Requirements Manual.
The B RWST level channel, LT-1QS-100B, will then fail low, the SRO will address Tech Specs for the failed RWST level channel.
A malfunction will then occur with the turbine valve position limiter causing a 100 mw load rejection, with a Rod speed malfunction that causes control rods to auto insert at 5 SPM, requiring the ATC to manually insert rods or borate the RCS.
At the same time, a malfunction will occur with the B main feed regulating valve controller, FCV-1FW-488, causing oscillations in the B SG level. IAW AOP 1.4.1, the BOP will manually stabilize and control level.
After level is stabilized, the BOP will take actions to Recover the Governor Valves from the Limiter IAW 1OM-26.4.AK.
The SRO will enter AOP 1.35.2, Load Rejection, to stabilize the plant and address DNB technical specifications.
The load rejection will cause reactor power to decrease to <49% (P-9).
A report from the field will state that there is a significant oil leak on the A Main feedwater pump requiring the BOP to shutdown the pump.
There will then be a loss of the main transformer due to Differential overcurrent causing an immediate turbine trip. The crew will enter AOP 1.26.1 and begin reducing Rx power. The rod speed remains at 5 SPM when in AUTO, requiring the ATC to manually insert rods.
When Rx power lowers to <13% or the condenser steam dumps are placed in Steam Pressure mode, the C 4Kv bus will fail, resulting in a loss of the C RCP and the B Main feedwater pump, the SRO will direct the ATC to manually trip the reactor.
The ATC will unsuccessfully attempt to trip the reactor from BB-B and BB-A and begin manually inserting the control rods as auto rod insertion capability failed when power reduced to < 38%.
The SRO will enter FR-S.1 with the ATC and BOP performing the IOAs.
When Rx power is <3% and after Emergency boration flow is established in FR-S.1, if the crew previously dispatched an operator to locally trip the reactor, the reactor will be locally tripped. The ATC will verify reactor power is <5% after which the SRO will return to E-0.
3 minutes after the Rx is locally tripped, a 1200 gpm LOCA will occur on the A loop resulting in an automatic SI, the B charging/HHSI pump will fail to automatically start on the SI signal.
Additionally, during the ATWS condition, auto start is inhibited for Auxiliary feed water pumps.
After returning to E-0, the SRO will determine that the RCS is not intact and transition to E-1.
The crew will shutdown the A and B RCPs due to meeting RCP trip criteria.
The scenario will be terminated at the lead evaluators discretion after the crew transitions to ES-1.2.
Expected procedure flow path is E-0 FR-S.1 E-0 E-1 ES-1.2.

1L21N2 After taking the shift at 100% power, BOL. The A CCR pump will trip due to a faulty breaker with a failure of the B to auto start. The crew will enter AOP 1.15.1. The ATC will manually start the B CCR pump, the crew will dispatch an operator to place the C pump in service on the AE 4kv bus. The SRO will address Technical Specifications.
The Master Pressure controller will then fail to 85% causing the PRZR spray valves to open. IAW AOP 1.4.1, the ATC will close the spray valves to stabilize RCS pressure. The ATC will manually control PRZR pressure for the remainder of the scenario. The SRO will address Technical Specifications for DNB.
Power Range Nuclear instrument, N-44 will then fail high causing the control rods to automatically insert. The crew will perform the Immediate Operator Actions for AOP 1.1.3, Unexpected Control Rod Movement. The ATC will identify the N-44 failure and place the rods in manual. The SRO will then transition to AOP 1.2.1C, Power Range Channel Malfunction, and direct the BOP to remove the failed channel from service. The SRO will address Tech Specs for the failed instrument.
A bearing will then begin failing on the turbine causing turbine vibrations to begin increasing, IAW the alarm response procedure, the crew will address the bearing degradation and perform a management directed power reduction at 2%/minute IAW AOP 1.51.1 to remove the turbine from service. After the reactor power has been reduced ~6%, the turbine bearing will fail causing vibrations to exceed 14 mils - requiring the turbine to be manually tripped.
Upon the Rx trip, a steam header break will occur in the turbine building. An automatic steamline isolation will occur, however the "C" Mainsteam line isolation valve will fail to automatically close requiring the BOP to manually close it. The fault will also result in an SI being required, however, Safety Injection will not automatically actuate, requiring manual actuation to initiate SI flow.
Aux Feedwater malfunctions will occur such that the turbine driven pump, 1FW-P-2 trips on start, 1FW-P-3A/B will not start.
The crew will enter E-0 on the reactor trip, and then enter FR-H-1 due to no available auxiliary feed water pumps.
During the immediate operator actions of E-0, the BOP will be required to manually open the exciter circuit breaker due to an auto open failure.
After Feedwater has been established using either the dedicated Feedwater pump, 1FW-P-4 or either Main feed pump, the crew will return to E-0, determine that SI is not required and transition to ES-1.1 to terminate SI flow.
The scenario will be terminated after the crew terminates SI flow in ES-1.1.
Expected procedure flow path is E-0 FR-H.1 E-0 ES-1.1.
Facility: BVPS Unit 1 Scenario No. 3 Op Test No.: 1LOT21 NRC Examiners: Candidates: SRO ATC BOP Initial IC 167(5): ~4.5% power, BOL, Xe increasing, CB D @ 110 steps, RCS boron - 1815 Conditions: ppm.

1L21N3 The crew will assume the shift at ~4.5% power with instructions to raise power in accordance with the reactivity plan and 1OM-52.4.B., Additionally, the turnover includes direction to place the "B" EHC pump, 1LO-M-9B, in service to support turbine roll upon taking the watch.
When the ATC performs a dilution IAW the reactivity plan, the dilution will not automatically shutoff requiring the ATC to manually stop the dilution.
After the power has raised to >5.5%, an A SG level transmitter, 1FW-LT-475, will fail high. The BOP will verify the SG level remains stable, the SRO will enter 1OM-24.4.IF attachment 1 and address TS for the failed channel. There are no control actions associated with this failure.
Additionally, after power has raised to >5.5%, C SG Bypass Feed regulating valve will fail while in Auto, failure will become evident as Rx power continues to be raised, the BOP will be required to identify the malfunction and take action to control FCV-1FW-499 in manual IAW AOP 1.4.1 Process Control Failure.
LT-1RC-459 will then drift high. The ATC will recognize the failure and respond IAW AOP 1.4.1 IOA's to remove the failed channel from service. The SRO will transition to the Instrument Failure procedure, 1OM-6.4.IF, attachment 1 and direct the ATC complete the removal of the 459 channel from service and then review applicable Technical Specifications in effect for the failed level transmitter.
A large steam fault will then occur on the B SG inside of CNMT, however the Rx will fail to automatically trip.
The ATC will trip the Rx and the crew will enter E-0 and transition to E-2 after diagnosing a faulted SG. The steam break is of a magnitude that will raise CNMT pressure above CIB actuation setpoint, however automatic CIB will not occur.
Additionally, the main steamline drain valves, TV-1MS-111A,B,C, fail to automatically close on the MSLI signal and the control room emergency ventilation system, CREVs, fails to automatically actuate on the CIB signal.
After the crew completes SG isolation IAW E-2, they will transition to ES-1.1.
The scenario will be terminated at the Lead Evaluators discretion after the crew has shutdown the Low Head SI pumps.
Expected procedure flow path is E-0 E-2 ES-1.1.

After Rx power has reduced ~10%, PT-1RC-444 will fail high causing the spray valves and PORV 455C to open, The ATC will be required to manually close spray valves and PORV, PCV-1RC-455C, IAW AOP 1.4.1 immediate operator actions. The US will enter AOP 1.4.1 and then transition to 1OM-6.4.IF, Attachment 2 and determine applicable Tech Spec actions. PORV 455C will fail to completely reseat, the ATC will then attempt to close the MOV block valve, MOV-1RC-535, which will fail to close.
Due to the leaking PORV, the SRO will direct the ATC to manually trip the Rx. When the ATC attempts to trip the Rx from BB-B, the Trip switch will fail, the ATC will then trip the Rx using BB-A trip pushbutton.
The Rx trip will cause a 650 gpm SGTR to occur on the A SG.
The crew will progress thru E-0, the BOP will identify that Reheat steam and SG blowdown flowpaths both failed to automatically isolate on the trip and take appropriate manual actions.
The crew will transition to E-1 at the check the PORVs step of E-0, then transition to E-3 due to the indications of a SGTR.
The crew will progress thru E-3, after the crew completes the RCS cooldown, they will transition to ECA-3.1 due to the open PORV.
The scenario will be terminated at the Lead Evaluators discretion when the crew performs an RCS cooldown IAW ECA-3.1, recognizes 100F/hr cooldown limit and demonstrates actions to control the cooldown to within limits.
Expected procedure flow path is E-0 E-1 E-3 ECA-3.1.

1L21N5 After taking the shift, IAW 1OM-23B.4.G, the crew will startup the standby Heater Drain pump, 1SD-P-1B and shutdown 1SD-P-1A.
The turbine driven AFW pump Trip throttle valve will then fail, the SRO will address TS implications of AFW pump being OOS.
The A SG Channel 3 steam pressure transmitter, PT-1MS-475, will fail low, IAW AOP 1.4.1, the BOP will place the A MFRV in manual to control level, and the SRO will direct placing the alternate channel in service using 1OM-24.4.IF, Attachment 4. After FCV-1FW-478 is returned to AUTO, the SRO will address Technical Specifications.
The "A" Main feedwater pump will spuriously trip, the crew will enter AOP 1.24.1 and reduce power to less than 52%. The control rods will fail to auto insert requiring the ATC to manually insert control rods and borate for the power reduction.
During the power reduction, the A RCP seal leakoff flow will begin to decrease, the crew will respond to the Annunciator, A3-101, for Hi Seal Vent Pot Level via the ARP and then via AOP 1.6.8, Abnormal RCP Operation, the crew will continue to monitor seal leakoff flow as it decreases. Seal leakoff flow will decrease to < 0.8 gpm with an increase in radial bearing temperature which meets the immediate trip criteria in AOP 1.6.8. The ATC will manually trip the reactor, trip the A RCP and then close the spray valve.
As a result of the Rx trip, a 300 gpm SBLOCA will occur on the A loop.
The turbine will fail to completely trip on the reactor trip, GV-2 and TV-2 will fail to close requiring a manual turbine trip.
Additionally; PORV, PCV-1RC-455D will fail open causing a Safety Injection due to low PRZR pressure, requiring closure of the block valve. During the transfer to offsite power, the A 4kv bus will trip due to overcurrent; the #1 EDG will start then trip on overspeed.
With the AE 4kv emergency bus de-energized, A "B" train SIS Injection valve, MOV-1SI-867D, will fail to auto open; therefore, with no Safety Injection flow, the crew will be required to manually open MOV-1SI-867D to restore HHSI flow.
The crew will enter E-0, transition to E-1 due to containment parameters and then to ES-1.1 to terminate Safety Injection.
The scenario will be terminated when normal charging flowpath is established in ES-1.1.
Expected procedure flow path is E-0 E-1 ES-1.1.
