| ==SUMMARY==
| |
| : 2014 NRC EXAM SCENARIO 1 Turnover provided to the crew is - The plant is operating at ~49% power in BOL. Criticality was achieved 8 hours ago, 74 hours after a trip from 100% power. A plant startup in accordance with GP-005, Power Operation Mode 2 to Mode 1, is in progress. After initial turbine loading, the load increase has been performed at 4 units/min. The unit is currently at ~49% power. The National Weather Service has forecasted thunderstorms for the New Hill area and the actions for AP-301, Seasonal Weather Preparations and Monitoring have been completed by the crew.
| |
| Plant risk condition is YELLOW due to startup.
| |
| A startup has commenced and the crew has been directed to continue the power increase using GP-005 to ~52% power at a ramp rate of 4 DEH units/minute. At ~52% power or greater than 6.4 MPPH feedwater flow, the Turbine will be placed in hold and the BOP will place the second Main Feedwater Train Pump in service per OP-134.01, Feedwater System, Section 5.4.
| |
| Following the start of the B MFW Pump the crew will continue to ramp the unit towards full power operation.
| |

| |
| * 1SI-3, Boron Injection Tank Outlet valve, Tech Specscontinued Event 1: Continue plant startup to ~52% power: The crew will perform a power increase of approximately 3%-5% power then place the Turbine to hold until the (BOP) starts the standby B MFW pump IAW OP-134.01 Section 5.4. Following the start of the B MFW pump the crew will continue efforts to raise power to the Lead Examiners discretion. For the reactivity manipulation it is expected that the SRO will conduct a reactivity brief, the RO will dilute and monitor auto rod withdrawal per the reactivity plan and the BOP will operate the DEH Controls as necessary to raise Main Turbine power.
| |
| Event 2: Pressurizer PORV 445A Leakage: This failure will cause PRZ PORV 445A to leak, resulting in rising PRT pressure and level. PORV Line Temp indicator TI-463 will increase as observed on the MCB and the crew will respond IAW ALB 009-8-2, Pressurizer Relief Discharge High Temp. The crew may utilize AOP-016, Excessive Primary Plant Leakage, Attachment 5 to determine which PORV is leaking by isolating each PORV Block valve individually until the leaking PORV is identified.

The crew should dispatch an operator to locally investigate the cause of the alarm. The report from the AO will be that all transformer cooling is lost. The crew should recognize this meets the entry conditions of AOP-039, Startup And Unit Auxiliary Transformer Trouble. The crew should monitor EFRIS to determine the UAT 1A temperature is approaching the limit that will require the transformer to be unloaded within 30 minute and the CRS should direct the BOP to transfer the house loads from the UAT 1A to the SUT 1A using OP-156.02, AC Electrical Distribution.

This will result in multiple NSW alarms and the crew should enter AOP-022. Once immediate actions are complete the crew should use the AOP to start up the standby NSW pump and verify proper system operation. While NSW system pressure is low the ESW system will automatically start and isolate into the A and B train headers. With lower temperature ESW water providing cooling into Containment the potential exist for a low pressure condition to occur. This will be indicated by ALB-028-5-1, Containment Air High Vacuum. The SRO should evaluate Tech Spec 3.6.1.4.

| |
| Event 6: MAJOR - Steam line Break on B SG inside Containment. Once RCS pressure control has been established to the satisfaction of the Lead Examiner a Steam Line Break inside Containment on the B SG will occur. The crew should enter and carry out the immediate actions of EOP-E-0, Reactor Trip Or Safety Injection.
| |
| The crew should diagnose that a LOCA is NOT in progress and transition from EOP-E-0 to EOP-E-2, Faulted Steam Generator Isolation.
| |
| While the crew is performing actions of EOP-E-2 the Containment pressure will continue to rise beyond 10 psig which will actuate a Containment Spray and a Phase B isolation signal. This will require ALL RCPs to be secured.
| |
| All RCPs will need to be manually tripped within 10 minutes of a Phase B isolation signal.
| |
| (Critical Task)
| |
| Event 7: Failure of Auto AFW Isolation on B SG. The crew should identify that an actuation signal for AFW Auto Isolation has failed on the B SG and manually isolate AFW flow to the B SG. (Critical Task)
| |
| Event 8: Failure of PZR PORVs to auto open when required. As RCS pressure increases the crew will be required to secure SI flow. If SI flow continues the RCS pressure will continue to increase as the PZR fills. If or when RCS pressure exceeds the PORV lift setting of 2335 psig the PORVs will NOT automatically open. The operator can manually open and close the PORVs to prevent an overpressure condition which could cause the RCS Safety Relief Valves to lift at 2485 psig. The Technical Specification RCS Safety Limit is 2735 psig which is 110% of design pressure.
| |
| Event 9: Failure of BIT outlet isolation valve 1SI-4 to close. While implementing EOP-E-2 the crew will be directed to reset SI and shut BIT outlet valves then establish a normal Charging lineup. Prior to the establishment of the Charging lineup High head SI flow should be isolated.
| |
| When the crew attempts to shut 1SI-4 from the MCB the valve will not close. RNO actions direct locally shutting the valves. The crew will direct an Aux Operator to locate and shut the valves. The actions and locally shutting 1SI-4 need to be performed prior to filling the RCS to solid conditions which could cause the SRVs to lift. (Critical Task)
| |
| Event 10: Source Range channels will fail to energize post trip due to IR NI-35 under compensation. The crew will need to identify the failure of the SR instrumentation MCB indication and audible counts. They will then manually energize the SR channels to establish an audio count rate.
| |
| The scenario will end when Safety Injection has been terminated and the crew restores letdown to service while implementing EOP-ES-1.1, SI Termination. With PZR level lowering and RCS Hot Leg Temperatures stable or lowering the RCS pressure challenge will be removed.
| |
| Harris 2014 NRC Exam Scenario 1 Rev. FINAL
| |
| | |
| Appendix D Scenario Outline Form ES-D-1 HARRIS 2014 NRC SCENARIO 1 CRITICAL TASK JUSTIFICATION:
| |
| : 1. Manually trip all RCPs within 10 minutes of a Phase B isolation signal Securing RCPs during a large steam break inside Containment is procedurally required when Containment pressure has exceeded the High 3 setpoint of 10 psig. Exceeding this pressure causes a Phase B actuation that isolates CCW flow to the RCP heat exchangers. If the RCPs are left operating they will overheat and become inoperable. Due to the rapid pressure increase in Containment from this event EOP-E-0 continuous action step 16 RNO b requires the crew to secure ALL RCPs. This action should be accomplished within 10 minutes of the Phase B actuation and prior to transitioning out of EOP-E-0.
| |
| : 2. Isolate AFW flow to B Steam Generator prior to exiting EOP-E-2.
| |
| Failure to isolate a faulted Steam Generator that can be isolated causes challenges to the Critical Safety Functions beyond those irreparably introduced by the postulated conditions. Also, depending upon the plant conditions, it could constitute a demonstrated inability by the crew to recognize a failure of the automatic actuation of an ESF system or component. This critical task requires the crew to recognize an automatic actuation should have occurred of an ESF system or component but has not and then take manual operator actions to perform the isolation.
| |
| : 3. Shut BIT Outlet valve 1SI-4 prior to establishing flow through the charging header.
| |
| Isolation of Safety Injection is required to allow the operator to stabilize RCS plant conditions. Eventually the Pressurizer will fill with water rendering pressurizer control ineffective. Consequently, in order to decrease RCS pressure to conserve makeup water, Safety Injection flow must be decreased. Because Safety Injection flow cannot be throttled, once the criteria to reduce Safety Injection flow is met Safety Injection is terminated by isolating Safety Injection flow, reducing to one CSIP in operation and realigning the CSIP discharge to the normal charging header. Shutting the BIT outlet valves is the first step in realigning normal charging to the RCS. Not shutting 1SI-4 prior to establishing a normal Charging lineup will cause simultaneous flow through the Charging and SI lines and cause a CSIP run out condition indicated by oscillating discharge pressure.
| |
| Note: An unanticipated critical task may be created in a scenario should an applicants action or lack of action cause an unexpected RPS or ESFAS actuation. A critical task may be assigned and graded as unsatisfactory even if corrected by another team member prior to the unanticipated RPS/ESFAS actuation. Should the applicant self-correct the action or inaction prior to the unanticipated plant response, a critical task failure should not be assigned to the applicant.

| ==SUMMARY==
| |
| : 2014 NRC EXAM SCENARIO 2 The plant is at 3% power, MOL, plant startup in progress. GP-005, Power Operation (Mode 2 to Mode 1) is being implemented. The crew transitioned to Mode 1 to start up the Main Turbine when secondary chemistry parameters forced the crew to lower power below 5%. Criticality was achieved 2 hours ago, 72 hours after a trip from 100% power. The National Weather Service has forecasted thunderstorms for the New Hill area and the actions for AP-301, Seasonal Weather Preparations and Monitoring have been completed by the crew. Plant risk condition is YELLOW due to startup.
| |
| The following equipment is under clearance:
| |
| * Circulating Water Pump B-NNS is under clearance due to high vibrations on the motor bearing. Has been under clearance for 48 hours. Repairs are expected to be completed within 2 hours.
| |
| * B Gland Seal Exhauster Fan is under clearance for motor repairs. Has been under clearance for 8 hours. Repairs are expected to be completed within 24 hours.
| |
| * B DEH Pump is under clearance for motor repairs. The pump has been unavailable for 8 hours. Repairs are expected to be completed within 24 hours.
| |
| Event 1: Start power escalation to 4 - 8% to raise turbine speed to 1800 rpm. Start power escalation to 6%. The crew performs an ascension in Reactor power and with the Turbine at 1700 rpm, transfers control from the Throttle Valves to the Governor Valves and rolls the turbine up to 1800 rpm. They then prepare to proceed with GP-005.
| |
| Event 2: Trip of the A Circ Water Pump and Discharge valve, 1CW-10 fails to automatically shut. This malfunction can be inserted once the lead evaluator is satisfied with the crews ability to control the escalation of reactor power. The crew should identify the trip of the A Circ Water pump from annunciator ALB-021-4-4 and respond using the APP. The trip of the Circ Water pump is entry conditions for AOP-012, Partial Loss Of Condenser Vacuum, and the crew may enter the AOP without referencing the APP. The BOP should identify that the discharge valve for the A Circ Water pump,1CW-10, did not automatically shut and should attempt to shut the valve by taking the Circ Water pump control switch to stop.
| |
| The crew should monitor condenser vacuum for reactor trip criteria and discuss continuing with the GP-005 to raise power with only 1 Circ Water Pump in operation until B Circ Water pump is restored or if GP-006, Normal Plant Shutdown From Power Operation To Hot Standby (Mode 1 To Mode 3) should be implemented to shut down the unit.

| Event 3: Shaft Shear A CCW Pump with standby CCW pump failure to auto start. The standby B CCW Pump fails to Auto Start due to a pressure transmitter failure (instrument is isolated therefore pressure decrease is not sensed). The crew should recognize the loss and enter AOP-014, Loss of Component Cooling Water. AOP-014 will direct the restoration of the CCW system. The RO will be directed by the SRO to manually start the B CCW (or will have started it IAW AD-OP-ALL-1000 when it did not auto start). The SRO should also evaluate Tech Spec 3.7.3, Component Cooling Water System.
| |
| The SRO should also prepare OMM-001, Operations Administrative Requirements, Attachment 5 Equipment Problem Checklist for the failure.
| |
| Event 4: Pressurizer Level Transmitter for LT-460 fails low which isolates letdown. Must restore letdown per APP - Controlling Pressurizer level channel LT-460 fails low can be inserted. The crew should respond in accordance with alarm response procedure APP-ALB-009. The crew should take Charging FCV-122 to Manual and maintain Pressurizer level within the directed control band and shift level control to an alternate channel. The SRO should evaluate Tech Specs and identify Tech Spec 3.3.1, action 6 is NOT applicable as the unit is below the P-7 setpoint of 10% Reactor power.

| Event 7: A MFP trips with MFP B failure to start. Maintain Rx power <10% and initiate AFW in accordance with AOP-010, Feedwater Malfunctions - A MFP trip, with the B MFW pump failing to auto start may be inserted once Pressurizer level has been stabilized and letdown restored. Both MDAFW pumps fail to auto start but can be started in the MCR. The crew may need to reduce power to be within AFW flow capacity in order to maintain SG water levels between 52% and 62% in accordance with AOP-010.
| |
| The SRO should also prepare OMM-001, Operations Administrative Requirements, Attachment 5 Equipment Problem Checklist for the failure.
| |
| Event 8: MAJOR - B SGTR occurs, 420 GPM ramped in over 3 minutes - SGTR on the B SG can be inserted following stabilization of secondary parameters in accordance with AOP-010. A 420 gpm tube leak will develop over 3 minutes. The crew will implement AOP-016, Excessive Primary Plant Leakage, due to the leakage. As the leak progresses, conditions will be met to require a reactor trip. The crew will initiate a reactor trip and implement EOP-E-0, Reactor Trip Or Safety Injection actions.
| |
| Event 9: Auto SI failure. Failure caused by 2 SI (Train A and B) Low Pressurizer Pressure relay failures. Failure of one MCB SI manual actuate switch - When conditions requiring a safety injection are met, automatic SI will not occur. One manual SI switch is blocked. Manual initiation of SI is possible with the other switch.
| |
| Event 10: B SG PORV fails open in auto due to PT-308B failing high, Operator can close manually (Critical Task) - When the BOP is directed to energize busses 1A1 and 1B1, the SG A PORV will fail open in automatic. The SG PORV may be closed manually at the MCB. The crew may recognize the PORV being open based on alarms and MCB indications and take pre-emptive action to close the PORV. If the PORV is not closed, MCB indications may require transition to EOP-E-2, Faulted Steam Generator Isolation and then to EOP-E-3, Steam Generator Tube Rupture, to mitigate the ruptured SG. EOP-E-3 will implement actions to isolate the ruptured SG and depressurize the RCS to eliminate break flow. (Critical Task)
| |
| Terminate scenario once the RCS has been depressurized and all but one CSIP is stopped in accordance with EOP-E-3.
| |
| Harris 2014 NRC Exam Scenario 2 Rev. FINAL
| |
| | |
| Appendix D Scenario Outline Form ES-D-1 HARRIS 2014 NRC SCENARIO 2 CRITICAL TASK JUSTIFICATION:
| |
| : 1. Manually close B SG PORV prior to improper transition to EOP-ECA-3.3 Failure to isolate the ruptured SG causes a loss of differential pressure between the ruptured SG and the intact SGs. Upon the loss of differential pressure, the crew must transition to an emergency contingency procedure (ECA-3.3) that constitutes an incorrect performance that necessitates the crew taking compensating action which complicates the mitigation strategy.
| |
| : 2. Depressurize the RCS to minimize primary to secondary leakage prior to SG B exceeding 100% level Failure to depressurize the RCS needlessly complicates mitigation of a SGTR event by allowing the Reactor Coolant leak to continue. It constitutes a significant reduction of safety margin beyond that introduced by the SGTR event analysis.
| |
| If primary to secondary leakage is not stopped the SG pressure will increase until either the SG PORV or Safety valve(s) open releasing radioactivity to the environment. If leakage is allowed to continue the increased inventory will result in water release through the PORV once SG overfill conditions are reached.
| |
| At the Harris plant, a NR level of 95% is the value at which overfill conditions will start to exist and the adverse effects of the condition may start to manifest themselves. Failure criteria of NR level of 100% is used since an increase in level can no longer be monitored and overfill conditions are occurring including the possibility of filling the steam lines with liquid.
| |
| Note: An unanticipated critical task may be created in a scenario should an applicants action or lack of action cause an unexpected RPS or ESFAS actuation. A critical task may be assigned and graded as unsatisfactory even if corrected by another team member prior to the unanticipated RPS/ESFAS actuation. Should the applicant self-correct the action or inaction prior to the unanticipated plant response, a critical task failure should not be assigned to the applicant.

| |
| : 2014 NRC EXAM SCENARIO 3 The plant is at 88% power with middle of life core conditions and the turbine in HOLD. AH-3 has been leaking for the last 5 days. Service water tube plugging plans have been developed and Maintenance is ready to plug the leaking tube. To allow personnel to enter Containment and work on the air handler the unit will be reduced to 60% power.
| |
| A power reduction is in progress IAW with GP-006, Normal Plant Shutdown From Power Operation To Hot Standby (Mode 1 To Mode 3) step 9.
| |
| The desired load rate change is 4 DEH units per minute. Load is set at 120, and the turbine is in hold.
| |
| The National Weather Service has forecasted thunderstorms for the New Hill area and the actions for AP-301, Seasonal Weather Preparations and Monitoring have been completed by the crew. Plant risk condition is YELLOW due to the downpower.
| |
| The following equipment is under clearance:
| |
| * AFW Pump A-SA is under clearance due to high vibrations on the motor bearing. The pump has been inoperable for 4 hours due back in 24 hours, awaiting motor bearing parts from vendor. Tech Spec 3.7.1.2 LCO Action a.
| |
| * B DEH Pump is under clearance for motor repairs. The pump has been unavailable for 8 hours. Repairs are expected to be completed within 24 hours.

| |
| * Letdown Orifice Isolation Valve 1CS-9 is under clearance for breaker inspection. Tech Spec 3.6.3 LCO Action b applies. OWP-CS-09 has been completed.
| |
| Event 1: Crew performs a power reduction IAW GP-006. For this reactivity manipulation it is expected that the SRO will conduct a reactivity brief, the RO will borate per the reactivity plan and the BOP will operate the DEH Controls as necessary to lower power. After approximately a 3-5% power reduction 85 to 83% Event 2 will begin.
| |
| Event 2: Feed flow transmitter on C SG FT-497 Channel IV (selected for 1C SG) fails low -
| |
| additionally, FRV C fails in Auto. When the plant is in a stable condition, the Lead Evaluator can cue the SG C Feed Flow channel failure. The crew should respond in accordance with the alarm response procedure and AD-OP-ALL-1000. The BOP will be controlling SG C level with the FRV in MANUAL and may switch controlling FF channels to restore control to AUTO. The crew will take the channel out of service using OWP-RP-10, Reactor Protection, SF/FF Loop 3.
| |
| IF FRV C is placed back into Auto the controller will fail to 60% output and the valve will respond by placing the FRV controller back to MANUAL and adjusting Feed Flow accordingly.
| |
| The SRO should evaluate the following Tech Specs for failure of FT-497:
| |
| T.S. 3.3.1: As a minimum, the Reactor Trip System instrumentation channels and interlocks of Table 3.3-1 shall be OPERABLE Harris 2014 NRC Scenario 3 Rev. FINAL

| |
| The crew should implement OWP-RP-10 for this failure.
| |
| The SRO should also prepare OMM-001, Operations Administrative Requirements, Attachment 5 Equipment Problem Checklist for the failure.
| |
| Event 3: VCT Level Channel 115 fails low. This failure will cause automatic make up to the VCT to initiate. The crew should enter AOP-003, Malfunction of Reactor Makeup Control, identify the failed level transmitter, and secure the automatic makeup caused by the failed instrument.
| |
| Event 4: Reactor Primary Shield Cooling Fan S2-1A trips. The crew will respond to ALB 027-5-5 and evaluate the condition. The standby fan will be started in accordance with the alarm response. A fan is required to be in operation anytime RCS temperature is greater than 140°F.
| |
| The SRO should also prepare OMM-001, Operations Administrative Requirements, Attachment 5 Equipment Problem Checklist for the failure.
| |
| Event 5: Trip of the running A Charging Pump breaker. The crew will enter AOP-018, Reactor Coolant Pump Abnormal Conditions and carry out the immediate actions. The crew should isolate letdown and then implement actions to place the B Charging Pump in service. The crew will have to secure the ASI pump after the CSIP is started and evaluate the boration caused by the ASI pump running. The efficiency that the crew has in progressing through AOP-018 to the point of securing the ASI pump will determine the amount of boric acid added to the RCS through the RCP seals. This could require the SRO to direct the RO and BOP to coordinate Reactor and Turbine controls (dilute, rod movement and / or Turbine reduction) to accommodate the boron addition for Tavg/Tref stabilization.

| |
| ACTION: a. With one ECCS subsystem inoperable restore the inoperable subsystem to OPERABLE status within 72 hours or be in at least HOT STANDBY within the next 6 hours and in HOT SHUTDOWN within the following 6 hours.
| |
| The SRO should also prepare OMM-001, Operations Administrative Requirements, Attachment 5 Equipment Problem Checklist for the failure.
| |
| Event 6: Restore letdown IAW OP-107, Chemical and Volume Control System (Evaluators discretion) - once the B Charging Pump is in service, the crew will restore letdown IAW OP-107 Section 5.4 to establish inventory control. Once letdown has been restored, Tech Specs have been evaluated for the loss of the A CSIP, and the crew response to the boron addition from the ASI system have been addressed to the satisfaction of the Lead Examiner the next event can be initiated.

| |
| Event 7: MAJOR - LBLOCA. The crew should implement EOP-E-0, Reactor Trip or Safety Injection, and transition to EOP-E-1, Loss of Reactor or Secondary Coolant.
| |
| During the implementation of EOP-E-1 plant conditions will require the CRS to transition to EOP-FR-P.1, Response To Imminent Pressurized Thermal Shock. Plant conditions will also require the crew to evaluate the need to transition to EOP-FR-C.2 based on RVLIS level fluctuations from the LOCA and input from the ECCS components. After implementation of the FR procedures the crew will return to EOP-E-1.
| |
| Event 8: The A RHR Pump will fail to auto start on sequencer operation but may be started manually from the MCB after Load Block 9 manual permissive is available.
| |
| Event 9: Shortly after entering EOP-E-0, the crew should recognize that the Foldout Criteria for securing all RCPs has been met and carry out that action. The RCPs must be manually tripped within 10 minutes of receiving a Phase B isolation signal. (Critical Task).
| |
| Pressure in Containment will continue to rise due to the LOCA and a Containment Spray Actuation setpoint will be reached. Both Containment Spray Pumps will fail to automatically start and at least one pump will need to be manually started with a flow path established to Containment (Critical Task).
| |
| Without Containment Spray in service, an ORANGE path will be met for Containment. The crew will not be required to make the transition to EOP-FR-Z.1, Response to High Containment Pressure, if they start and align at least on Containment Spray pump.
| |
| Event 10: When RWST level reaches 23.4%, the crew will transition to EOP-ES-1.3, Transition to Cold Leg Recirculation. 1SI-300 and 1SI-310 will fail to automatically open when RWST level reaches 23.4% and will need to be manually opened (Critical Task).
| |
| Once cold leg recirculation has been established, the scenario may be terminated.
| |
| Harris 2014 NRC Scenario 3 Rev. FINAL
| |
| | |
| Appendix D Scenario Outline Form ES-D-1 HARRIS 2014 NRC SCENARIO 3 CRITICAL TASK JUSTIFICATION:
| |
| : 1. Manually trip all RCPs within 10 minutes of a Phase B isolation signal Securing RCPs during a large break LOCA inside Containment is procedurally required when Containment pressure has exceeded the High 3 setpoint of 10 psig. Exceeding this pressure causes a Phase B actuation that isolates CCW flow to the RCP heat exchangers. If the RCPs are left operating they will overheat and become inoperable. Due to the rapid pressure increase in Containment from this event EOP-E-0 continuous action step 16 RNO b requires the crew to secure ALL RCPs. This action should be accomplished within 10 minutes of the Phase B actuation and prior to transitioning out of EOP-E-0.
| |
| : 2. Align one train of Containment Spray (CT) System for operation The CT System at HNP is designed to remove iodine from the Containment internal atmosphere. Actuating at least one train of CT is critical on the basis of iodine removal assumptions made in the FSAR. Since the event in this scenario is a large break LOCA this task should be completed prior to exiting E-0 based on continuous action step step 16 Check CNMT Pressure - HAS REMAINED LESS THAN 10 PSIG. RNO statement is to verify CNMT spray - ACTUATED.
| |
| It will not be actuated and require the crew will manually start at least one Containment Spray pump and then align the system for operation prior to exiting EOP-E-0. NOTE: the WOG Critical Task analysis states that this task should be completed prior to transition out of EOP-FR-Z.1 but since the event will cause the Containment pressure to quickly rise the continuous action statement in EOP-E-0 would be applicable. EOP-FR-Z.1 would not apply until the crew exits EOP-E-0 and transitions to EOP-E-1, step 1 where they would initiate monitoring of Critical Safety Function Status Trees. At this step the crew would identify that an ORANGE path condition to enter EOP-FR-Z.1 is present and at step 3.e they would verify CNMT spray pumps - RUNNING then align the system for injection.
| |
| : 3. Transition to Cold Leg Recirculation Improper performance or omission by an operator to correctly establish a RCS Cold Leg Recirculation line up will result in direct adverse consequences or a significant degradation in the mitigative capability of the plant. The establishment of the Cold Leg Recirculation lineup must be completed after the RWST level has lowered to < 23.4% and prior to the depletion of the RWST to a level <3%. This task is expected to be completed while performing the actions of EOP-ES-1.3, Transfer to cold leg recirculation. If the A RHR pump suction source remains aligned to both the Containment Recirc Sump and the empty RWST the RHR pump suction and discharge pressures will rapidly drop. Critical to complete suction lineup prior to the A RHR pump loss of suction which could potentially damage the pump and cause the pump to become inoperable at a time that it may be required to be in operation. (Suction and discharge pressure will rapidly reduce to ~0 psig upon loss of pump suction).
| |
| Note: An unanticipated critical task may be created in a scenario should an applicants action or lack of action cause an unexpected RPS or ESFAS actuation. A critical task may be assigned and graded as unsatisfactory even if corrected by another team member prior to the unanticipated RPS/ESFAS actuation. Should the applicant self-correct the action or inaction prior to the unanticipated plant response, a critical task failure should not be assigned to the applicant.

| A failure of the Vidar in the DEH computer has resulted in a plant trip in the past. This failure would affect operation in Operator Auto, and can be detected in either of the following ways:
| |
| * If OSI-PI is available, the process book PLANTSTATUS.PIW, DEH Trends function of the Plant Process Computer: DEH (menu) contains a point for DEH MEGAWATTS. With a failure of the Vidar, this point will not be updating.
| |
| * If OSI-PI is NOT available, accessing the ANALOG INPUTS screen on the Graphics display computer (in the Termination Cabinet room near the ATWS panel) will show several points, most of which should be updating if the Vidar is functioning properly.
| |
| Procedure Caution:
| |
| * If the DEH graphics computer is out of service, VIDAR can be checked as updating on the operator panel as follows:
| |
| : 1) DEPRESS TURBINE PROGRAM display button.
| |
| : 2) CHECK TURBINE PROGRAM display button is illuminated.
| |
| : 3) CHECK REFERENCE and DEMAND displays indicate 0000.
| |
| : 4) DEPRESS 1577.
