Rev. 02
Narrative:
Event 1) The crew will perform a breaker functional test of LPCS Event 2) Due to a failure high on the Level 8 transmitter the crew will determine the equipment failure, and evaluate the Division 2 half scram, entering the appropriate Technical Specifications.
Event 3) A Safety Relief Valve will fail open, resulting in elevated suppression pool temperatures. Crew will lower power to 90% per AOP-0035 Open Safety Relief valve and to close the valve using front and back panel switches and then pulling fuses.
Event 4) The removal of the fuses in Event 4 will result in a Steam Leak in the drywell due to the closure of the SRV and resultant stress this places on the steam piping. This steam leak will progress into a steam line rupture. The crew will take actions to reduce the steam leak by a Reactor Scram and entry into EOPs upon receipt of a 1.68 psid signal.
Crew will take action to makeup to the RPV using feedwater and condensate, restarting the feedwater pumps which will trip on Level 8 resulting from the steam line rupture if Reactor pressure is still high. If pressure is lowered sufficiently injection with condensate will be required.
Event 5) Following the EOP entry, High pressure injection from the HPCS system will fail due to a failure of the HPCS injection valve to open. Crew will attempt to dispatch personnel to open the valve locally. Valve will not be open prior to termination.
Event 6) Following the EOP entry the crew will recognize that the Division 1 Diesel Generator started but failed to tie into the safety bus due to a bus fault. Bus fault will not be cleared prior to termination.
The scenario will terminate once the crew has restored level to 10 to 51 inch level band using Feedwater/Condensate injection Rev. 02 Page 2 OF 30

Rev. 02
Narrative:
Event 1) The crew will perform a startup of the A Feedwater Pump, BOP will startup Lube Oil system and ATC will start the feedwater pump.
Event 2) The crew will raise power with Reactor Recirculation flow at ~2% CTP per hour.
Event 3) The crew will respond to a upscale failure RMS-RE16A Containment PAM radiation monitor. (Tech Spec)
Event 4) Trip of the running CRD pump B, the BOP will start the alternate CRD pump and restore flow and pressure. The ATC operator will be monitoring for accumulator faults and CRD high temperatures. (Tech Spec)
Event 5) Equipment failure of one of the steam flow transmitters causes a steam flow-feed flow mismatch in the 3 element circuitry in the level control system.
This result in a lower flow demand, and a resultant lowering of level. Since there are 4 steam flow inputs, the loss of 1, bias the level setpoint to about 20 vessel level.
The ATC operator can take manual control of the master controller or go the single level control and allow the system to automatically control level Event 6) The plant suffers a loss of offsite power. This results in a loss of all Condensate and Feedwater flow, and power to the Reactor Protection System. Vessel level will lower, but a Reactor Scram has already occurred from the loss of power to RPS.
The Div. I & II diesel generators start and supply their associated buses. Div. III diesel generator fails to start on the loss of power signal resulting in the loss of HPCS injection.
Event 7) Following the EOP entry the crew will recognize that the RCIC Controller is failed down scale, resulting in no injection. The BOP can place the RCIC Flow Controller into manual and slowly open the governor valve to start injection. RCIC will trip at 90%
speed, meaning that no high pressure injection sources of necessary size are available. Before level drops below -186 the CRS will direct the opening of 7 ADS/SRV to lower pressure and allow injection by low pressure ECCS systems, per Alternate Level Control Event 8) Following the EOP entry the crew will recognize that the Division 3 Diesel Generator failed to start, and the safety related bus is de-energized. The diesel generator will not be started prior to termination.
The scenario will terminate once the crew has restored level to 10 to 51 inch level band using Low Pressure ECCS systems Rev. 02 Page 2 of 29

NARRATIVE:
EVENT 1) BOP Operator unloads and secures Division 1 Diesel Generator EVENT 2&3) APRM F fails upscale. This will cause a reactor half scram. The CRS will reference TS 3.3.1.1 and recognize only three APRMs per channel are required also TS 3.3.2.1 and TR 3.3.2.1 and recognize only 6 APRMs are needed for rod blocks. The crew should recognize that one APRM may be bypassed then bypass the APRM and reset the half scram. APRM F fails upscale resulting in a Single Rod Scram of rod 40-29.
EVENT 4&5) Trip of GML-FN1. GML-FN2 Iso Bus Duct Cooling fan will be started and then subsequently trip also. This requires that Generator loading be reduced to ~52%
of full power.
EVENT 6) As a result of starting to lower generator load, the turbine starts to experience high vibration. This vibration requires a Turbine Trip when it reaches 10 mils for 15 minutes or 12 mils immediate. As a result of the lowering power or high turbine vibration, the reactor is scrammed EVENT 7&8) When the scram is inserted, a hydraulic lock will prevent rods from inserting.
The crew will take actions in accordance with EOP-1A. Suppression Pool Temperature will require boration. Neither Standby Liquid Control system is available to inject Boron into the Core to shutdown the reactor.
Termination Criteria:
- All rods in as the result of resetting and initiating additional scram signals
- Reactor Level and pressure controlled in assigned bands or efforts underway to restore to assigned bands.
- All previously elevated primary containment parameters restored or are being addressed.

Appendix D Scenario Outline Form ES-D-1 Facility: River Bend Station Scenario No.: 4 Op-Test No.4 Examiners: __ Operators: SRO-______________
____________________________ ATC-______________
____________________________ BOP-______________
Initial Conditions: Startup is in progress. Reactor pressure is 90 psig. Reactor power 2%.
Turnover: Shift priorities: 1) Shift to CNM-P1B, secure CNM-P1C to support oil addition to CNM-P1C. CNM-P1C has a low oil level. 2) Warm up RCIC and place in standby per SOP-0035 prior to exceeding 150 psig. 3) Continue power ascension per GOP-0001 by withdrawing control rods per Step 50 of Reactivity Control Plan.
Additional operators are being called in to assist with other startup acitivities.

Narrative:
Event 1) Rotate CNM pumps per turnover sheet. Crew will start CNM-P1B and secure CNM-P1C to allow oil addition to CNM-P1C.
Event 2) Place RCIC in standby per SOP-0035. Crew will warm up the RCIC system via the steam bypass line. Once pressure is equalized across the steam supply valves, the crew will place RCIC in service by opening the containment isolation valves.
Event 3) The ATC operator will withdraw control rods in accordance with the Reactivity Control Plan in order to raise reactor power.
Event 4) B21-PTN078A fails upscale (Tech Spec.) This failure will cause a reactor half scram. The SRO will enter TS 3.3.1.1 Condition A and TS 3.3.6.1. Condition A. In both cases the channel is in the tripped condition as a result of the half scram.
Event 5) Div 3 HPCS 125VDC Bus Fault (Tech Spec). This bus loss will require entry into TS 3.8.9 Condition E which will require declaring HPCS and SWP-P2C inoperable. This will cascade into TS 3.5.1. Condition B and TS 3.7.1 Condition E.
Event 6) RCIC Steam Leak in the RCIC Room. Initial indication of the steam leak will be in the RHR A room due to the high temperature alarm set point (110°F) being lower than the RCIC Room. The SRO will enter EOP-0003, Secondary Containment and Radioactive Release Control and will direct a reactor scram.
Event 7) The ATC operator will place the Reactor Mode Switch to the Shutdown position to scram the reactor. RPS fails to insert control rods. The ATC will attempt alternate methods of rod insertion by depressing the RPS pushbuttons which will be unsuccessful. The ATC will then attempt insertion via the Alternate Rod Insertion System. Rods will be inserted with Alternate Rod Insertion.
Event 8) RCIC Inboard and Outboard Containment Isolation Valve (E51-F063 & E51-F064)
Fail to Close. The crew will attempt to isolate the leak once the source is identified.
The isolation valves will fail to shut. The valves will also fail to isolate when the automatic isolation signal is received due to high temperature.
The scenario will terminate when all rods are inserted, the reactor is depressurized and RCIC is isolated.
