2)

After the steam supply to AFW pump 1-1 is isolated in accordance with EOP E-2, Faulted Steam Generator Isolation, AFW pump 1-1 is ______________ of providing 100% of its rated AFW flow.

A. 1) will

2) capable B. 1) will

2) NOT capable C. 1) will NOT

2) capable D. 1) will NOT

2) NOT capable Proposed Answer: C. 1) will NOT 2) capable Explanation:

A. Incorrect. Plausible the TDAFW pump would start but unlike the Motor Driven AFW pumps, is not started by SI. It is started by 2 of 4 steam generators (the motor driven AFW pumps start on 1 of 4), AMSAC or 12 kV UV (all MDAFW pumps starts). Second part is correct. While the two leads feed a common line to the suction of the TDAFW pump, the steam supplies are 100% redundant and available flow from the AFW pump is unaffected by the closing of one of the steam supplies.

B. Incorrect. The TDAFW pump is not started by SI. It is started by 2 of 4 steam generators (only one is low), AMSAC or 12 kV UV. Second part incorrect. While the leads from the steam generators feed a common header, the amount of flow from the TDAFW pump is unaffected by closing one, each one can supply 100% of the steam flow required to have the pump supply its rated flow.

C. Correct. SI starts the motor driven pumps start. The TDAFW pump will not automatically start. The steam supplies are redundant, only one is necessary for the pump to supply rated flow.

D. Incorrect. First part is correct. Second part is incorrect. The flow available is unaffected by the closing of one of the two steam supplies.

Unit 1 is in MODE 5 The RCS is solid RCS pressure is 350 psig One train of RHR in service PCV-135, Low Press Letdn valve, is in AUTO RHR Letdown Flow is being maintained via CVCS HCV-133, RHR to LTDN Flow Cont Charging pump 1-3 is in service The running RHR pump trips.

As a result of the RHR pump trip, RCS pressure will _______1)_________ and CVCS Letdown pressure will ________2)__________.

A. 1) rise

2) rise B. 1) rise

2) lower C. 1) lower

2) rise D. 1) lower

2) lower Proposed Answer: B. 1) rise

2) lower Explanation:

A. Incorrect. With the loss of letdown due to the trip of the RHR pump and continued charging flow, RCS pressure will RISE. However, PCV-135 will close down to try and maintain letdown pressure which lowers due to the RHR pump trip (valve closes to raise letdown pressure and opens to lower letdown pressure).

B. Correct. Flow into (charging) and out of (RHR/letdown) the RCS was initially balanced.

When the RHR pump tripped, two things resulted: 1) the RCS pressure rose due to the flow imbalance, and 2) letdown line pressure lowered due to the loss of discharge pressure when the RHR pump tripped. PCV-135 will respond to the lowering letdown line pressure by closing to attempt to maintain pressure at setpoint.

C. Incorrect. RCS pressure rises due to charging adding inventory, while no RHR pump is running to remove inventory..When the RHR pump trips, letdown pressure lowers. PCV-135 will close down to attempt to raise pressure.

D. Incorrect. First part incorrect, RCS pressure will rise. Second part is correct..

A. Incorrect Throttling open HCV-670 will bypass the heat exchanger and shutting HCV-637/638 will reduce the flow through the heat exchanger resulting in a smaller cooldown rate..

B. Incorrect - Throttling open HCV-670 will bypass the heat exchanger and limit cooldown rate in addition opening HCV-670 will exceed the 5000 GPM maximum flowrate to the cold legs.

C. Incorrect. Throttling HCV-670 and HCV 637/638 shut will limit the flow through the RHR heat exchanger and reduce total flow to the RCS cold legs resulting in a reduced cooldown rate.

D. Correct. Throttling shut HCV-670 while opening HCV-637/638 will maintain the flowrate to the loops below the 5000 GPM limit in addition to increasing flow through the RHR HX to maintain the same RCS cooldown rate due to the reduced CCW flow to the RHR HX.

103 A2.03 Rating 3.5 Question 17 GIVEN:

A large break LOCA occurred on Unit 1 RCS pressure is 40 psig Containment pressure is 25 psig and rising No charging pumps are running No RHR pumps are running Both SI pumps are running For the accident in progress, the operator will _____1)_______ the RCPs because

_______________2)______________________.

A. 1) trip

2) of Phase A actuation B. 1) trip

2) of Phase B actuation C. 1) NOT trip

2) there is still cooling to the RCPs D. 1) NOT trip

2) there are no charging pumps running Proposed Answer: B.

1) trip 2) of Phase B actuation.

Explanation:

Applicability: In the scenario of this question, Phase A isolation occurs on SI, and Phase B isolation occurs at 22 psig containment pressure (malfunction on containment system). Phase B isolation closes containment isolation valves associated with RCP cooling (also an "operation" of a containment system). These valves are listed in procedure STP V-11 Containment Isolation Phase B Valves FCV-355, FCV-356, FCV-357, FCV-363, FCV-749, and FCV-750 as meeting Technical Specification 3.6.3 (Containment Isolation Valves) SR 3.6.3.8. As such, they are included in the Containment Technical Specification family and meet the K/A system designator for Containment (#103). Knowledge of RCP trip criteria is RO knowledge.

A. Incorrect. First part is correct. Second part plausible because Containment isolation occurs at Phase A, but the CCW valves to the RCPs remain open and do not close until Phase B occurs.

B. Correct. Loss of RCP motor cooling occurs when Phase B occurs (22 psig). RCPs are stopped to prevent damage to the motors due to overheating.

C. Incorrect. RCPs are tripped. Plausible because CCW pumps are still available, and it could be not known the effect of high containment pressure on the CCW supply to the RCPs.

D. Incorrect because the RCPs are being secured due to losing CCW cooling. Plausible because

DCPP L181 Exam Rev 2 they would not be tripped during a LOCA if there are no high head pumps running. This includes the charging and/or the SI pumps. If its not known the SI pumps constitute high head flow (thought of as intermediate head), this answer is plausible Technical

2) does not actuate Proposed Answer: A. 1) actuates 2) actuates Explanation:

A. Correct. The failure of one train of SI to reset means one train of CS will still have an SI signal present (PK08-20). As such, one train of spray will actuate. SI signal present is not required for Phase B, therefore, Phase B will actuate.

B. Incorrect. First part is correct. Second part incorrect. Plausible that its thought with one signal reset, both trains and therefore no train of spray will actuate C. Incorrect. First part incorrect. SI signal does not affect Phase B. If its thought that Phase B requires the SI signal, not containment spray and one SI signal removes the signal from the logic. This is similar to de-energizing Source Range nuclear instruments, only one IR channel is needed to energize P-6 and allow de-energizing both source ranges.

D. Incorrect. Both parts incorrect. Phase B does not require SI signal. If its thought that Phase B, like Containment Spray requires SI, and one reset removes the signal, this answer is plausible.

According to the background document for EOP ECA-0.0, the reason for stopping the depressurization when steam generator pressure is less than 300 psig is to prevent:

A. injection of accumulator nitrogen.

B. drawing a bubble in the reactor vessel head.

C. tube failure due to high RCS/steam generator DP.

D. challenging RCS Integrity Critical Safety Function.

Proposed Answer: A.

injection of accumulator nitrogen.

Explanation:

A. Correct. Per ECA-0.0 background, the target SG pressure for Step 18 should ensure that RCS pressure is above the minimum pressure to preclude injection of accumulator nitrogen into the RCS. The target SG pressure should be based on the nominal SG pressure to preclude nitrogen addition, plus margin for controllability (e.g., 100 psi).

B. Incorrect. During the depressurization a head bubble may occur (caution states the depressurization is not stopped if it occurs). Plausible as most procedures try to avoid bubble formation.

C. Incorrect. DP across steam generator U-tubes has a normal 1700 psid limit. This is not the concern during the depressurization.

D. Incorrect. This is the reason for stopping at 310°F.

2) 547°F Proposed Answer: C. 1) pressure is less than 1300 psig 2) 542°F Explanation:

A. Incorrect. Subcooling is used for many EOP transitions, SI termination, and RCP trip criteria, however, RCS pressure is the criteria used for RCP trip. Second part correct.

B. Incorrect. First part incorrect.. Second part is incorrect. If temperature is higher, action is taken to lower temperature to 547°F. Also, no load RCS temperature is 547°F and steps in the EOPs check is temperature is trending to 547°F.

C. Correct. Both parts correct. RCS pressure less than 1300 psig is the criteria for RCP trip. If temperature is low, action is taken to stabilize temperature at its current value to limit the inventory in the pressurizer in the event of an inadvertent SI.

D. Incorrect. First is correct. Second part is incorrect.

C. will be isolated by the operator closing TDAFW pump 1-1 Steam Inlet valve, FCV-95.

D. will be isolated by the operator closing both TDAFW pump 1-1 Steam Supply valves, FCV-37 and FCV-38.

Proposed Answer: D. will be isolated by the operator closing both TDAFW pump 1-1 Steam Supply valves, FCV-37 and FCV-38 Explanation:

A. Incorrect. The break is downstream of the steam valves to the TDAFW and can be isolated.

Plausible if its thought the break is upstream of the steam headers to the TDAFW pump. If so, the break would be unisolable.

B. Incorrect. The break is not isolated. Plausible if its thought the pressure is lowering in the 1-2 and 1-3 steam generators due to the TDAFW pump running.

C. Incorrect. FCV-95 is closed at power. If there was a leak downstream of the valve, the plant would not have tripped.

D. Correct. The break is downstream of the normally open FCV-37 and 38. Closing both valves will isolate the leak.

Unit 1 is at 100% power RCS pressure is 2235 psig and lowering slowly PRT pressure is 5 psig and rising slowly For the current plant conditions, what indication(s) would cause the crew to confirm there is seat leakage through a PORV for entry into OP AP-1, Excessive Reactor Coolant System Leakage?

1. PORV tailpipe temperature indication, TI-463, reads top of scale, 400°F

2. PORV tailpipe temperature indication, TI-463, reads 230°F and rising

3. Sonic Flow is indicated A. 1 only B. 2 only C. 1 and 3 D. 2 and 3 Proposed Answer: B. 2 only Explanation:

A. Incorrect. A reading at top of scale is most likely an instrument failure. Also, saturation temperature for 400°F is approximately 225 psig, well above the PRT pressure. Plausible if its thought temperature is driven by pressurizer temperature, 650°F.

B. Correct. The isenthalpic process would have tailpipe temperature going to saturation temperature for the PRT. At 5 psig, (20 psia), this temperature is approximately 230°F. Also, the sonic indicators, unlike the tailpipe temperatures, are on separate headers for each pressurizer safety and do not respond to steam leaking past a PORV, only safety steam flow.

C. Incorrect. Both parts are incorrect.

D. Incorrect. First part is correct. However, sonic flow will not respond to PORV leakby, only Pressurizer Safety leakby.

A. lower to zero.

B. lower to a minimum flow limited by a mechanical stop.

C. rise to runout conditions.

D. rise to a maximum flow limited by a mechanical stop.

Proposed Answer: D. rise to a maximum flow limited by a mechanical stop Explanation:

A. Incorrect HCV-637 will fail open raising flow. Plausible because it may be thought that the valve will fail closed on loss of air as there is not a mechanical stop on closing.

B. Incorrect. HCV-637 will fail open raising flow. Plausible because there is a mechanical stop to ensure some minimum flow (like there is for opening), then this is a logical answer.

C. Incorrect. HCV-637 will fail open raising flow. However, it is limited by a stop to prevent runout. If this is not known, runout is a logical answer.

D. Correct. RHR heat exchanger outlet valves (HCV-637 and 638) are fail open valves. With HCV-637 open (to its stop) flow can rise to between 3976 gpm and < 4319 gpm, limited by a mechanical stop. Flow to the loops will rise.

2) because RCP seal flow is now from RCS cooled by the thermal barrier heat exchanger Proposed Answer: D. 1) is NOT 2) because RCP seal flow is now from RCS cooled by the thermal barrier heat exchanger Explanation:

A. Incorrect. A trip is not required as long as CCW supplies the RCP thermal barrier. Plausible as SDS (passive Shutdown Seal) actuation is a concern if all cooling is lost and the seal heats up to greater than 260°F and the RCPs are tripped within 5 minutes of a complete loss of CCW cooling.

B. Incorrect. A trip is not required as long as CCW supplies the RCP thermal barrier. Plausible as 15 minutes is used as a time for actions such as making E-plan classifications or during a reactor start up prior to withdrawing control rods.

C. Incorrect. First part is correct. CCW cools the thermal barrier heat exchanger, it does not replace the charging injection. Plausible if the flow paths are not understood.

D. Correct. The loss of seal injection allows RCS to begin to flow up the shaft of the RCP.

This RCS is cooled to approximately 140°F as it travels up the shaft of the pump and enters the number 1 seal. This is acceptable as long as CCW is supplying the thermal barrier.

2) open Proposed Answer: D. 1) fully open 2) open Explanation:

A. Incorrect. Based on the current output, the sprays and PORVs will be open. The spray valves begin to open at a setpoint of 40.6% which corresponds to a pressure 25 psig above 2235 (2260). The spray valves are fully open at 71.9% or +75 psig (2310 psig). The PORVs open at 87.5% or 100 psig above setpoint (2335 psig) If the fully open spray valve setpoint is not known, its plausible to think only pressurizer spray valves are open.

B. Incorrect. Plausible if its thought the setpoints for less than fully open sprays and PORVs open overlap.

C. Incorrect. There is a pressure band when the sprays are open and PORVs closed, but this is from 71.9% to 87.5% (2310 to 2335 psig)

Per EOP FR-H.1, what action should be taken by the crew?

A. Fully open one TDAFW LCV to establish maximum AFW flow to one steam generator.

B. Fully open all TDAFW LCVs to establish maximum AFW flow to all steam generators.

C. Throttle open one TDAFW LCV to establish AFW flow of 25 to 100 gpm to one steam generator.

D. Throttle open all TDAFW LCVs to establish AFW flow of 25 to 100 gpm to each steam generator.

Proposed Answer: A. Fully open one TDAFW LCV to establish maximum AFW flow to one steam generator.

Explanation:

A. Correct. With core exit temperatures increasing, maximum flow to restore a heat sink as quickly as possible is necessary.

B. Incorrect because only one steam generator is used in order to limit potential faults to only that steam generator. Plausible because the need to re-establish a heat sink is urgent and the TDAFW pump would normally be used to feed all steam generators.

C. Incorrect because maximum flow to one steam generator is to be used if core exit thermocouples are rising. Plausible because 100 gpm is the top end of the allowable flow band (25-100 gpm) to one dry steam generator if core exit temperatures are lowering.

D. Incorrect because only one steam generator is used in order to limit potential faults to only that steam generator. Plausible because the TDAFW pump would normally be used to feed all steam generators, and the restricted flow band of 25-100 gpm would be used if core exit temperatures were stable or lowering.

A. CCP 1-1 and SIP 1-1 B. CCP 1-2 and SIP 1-2 C. CCP 1-3 and SIP 1-1 D. CCP 1-3 and SIP 1-2 Proposed Answer: B. CCP 1-2 and SIP 1-2 Explanation:

NOTE: bank question KA is EA2.2 which has wording that mirrors selected generic KA.

The limiting condition for operation is the application of the note which states: The ECCS CCPs and SI Pps should be stopped in alternate trains when possible. According to the DCPP background document the basis is so if one train is disabled, some flow will still be available.

A. Incorrect. The note before step 13 provides guidance to leave pumps in alternate trains.

running. This refers to power supplies such that if a single power supply was lost, that all running equipment would not be simultaneously lost. CCP 1-1 and SIP 1-1 are both from bus F and does not meet the alternate train guidance.

B. Correct. CCP 1-2 and SIP 1-2 meet the alternate train requirement because they are powered from Vital 4 kV buses G and H respectively.

C. Incorrect. Either CCP 1-1 or 1-2 should be running. CCP 1-3 is the non-ECCS CCP.

Plausible because CCP 1-3 is powered from bus G (train B) and SIP 1-1 is from bus F (train A).

D. Incorrect. Either CCP 1-1 or 1-2 should be running during accident conditions, although CCP 1-3 is functional, it is the non-ECCS CCP. Plausible because CCP 1-3 and SIP 1-2 are powered from different buses, which meets the guidance in the note prior to step 13.

Only one train of ASW is available.

When the crew completes the alignment, the reason only one RHR heat exchanger and three CFCUs will be in operation is to prevent:

A. runout of the ASW pump.

B. runout of the CCW pump.

C. flashing and water hammer in the ASW system.

D. exceeding CCW system temperature design limit.

Proposed Answer: D.

exceeding CCW system temperature design limit.

Explanation:

Design of the ASW (Diablo equivalent to Nuclear Service Water) system is to adequately remove CCW heat. EOP E-1.3 includes operator actions to limit the heat loads during post-LOCA cold-leg recirculation if less than two ASW pumps and two CCW heat exchangers are in Service (a loss of one train).

A. Incorrect. With a single train of CCW in service, its plausible the student could focus on the single CCW train and believe runout is a possibility. The problem is due to the lack of cooling (from ASW), CCW heat removal is reduced to the point that if loads are not restricted, design temperature could be exceeded.

B. Incorrect. The system is designed for one pump to supply both CCW trains during normal operation without runout. Plausible because, if one train is supplying both trains of CCW, then its possible to think the loads could cause the only running ASW pump to approach runout.

C. Incorrect. Temperature remains less than saturation. Plausible because if two trains of CCW were put into service with only one train of ASW, temperature will rise.

D. Correct. The heat load of all the loads on the CCW with only one ASW train could cause the system to not be able to meet its purpose to remove heat from the CCW system and the CCW system could exceed its design temperature Technical

A. Incorrect. Incorrect. Pressurizer level will increase, but after pressure begins to rise and the system is refilled. RCS pressure is checked in ECA-1.2 B. Correct. RHR is isolated, one train at a time. If the leak is isolated, pressure will respond and quickly repressurize the system as SI flows into the now intact system.

C. Incorrect. Both parts incorrect. RHR is isolated, as it is the low pressure system and deemed to be the most likely location for a LOCA outside containment. CCW plausible as it is also a low pressure system that is connected to the RCS and RHR. The procedure checks RCS pressure not pressurizer level.

2) lit Explanation:

Candidate must understand the reason the reactor trip breakers would/would not be open and why SI would or would not actuate for a loss of 2 instrument buses in order to answer the question successfully.

A. Incorrect. Second part is correct. Loss of PY-14 causes a loss of one train of SI, however, SI actuates and both RTBs open.

B. Incorrect. Both RTBs open. One train of SI actuates and the PK will be lit due to the coincidence met for actuation due to the loss of two trains of bistables.

C. Correct. Both RTBs UV coils will de-energize and cause a reactor trip due to 2 trains of trip bistables tripping on the loss of power to the PYs. While one train of slave relays for SI is de-energized, SI actuates for the second train and PK08-21 will be lit.

If its thought its turbine power for P-8 (as it is with P-13 or C-5), then power would be below P-8 and would not cause a trip. Loop flow will lower but stabilize at approximately 30% due to reverse flow from the other loops.

B. Incorrect. First part incorrect, power is above P-8 and the RCP trip will cause a reactor trip.

Second part is correct, flow lowers but because of reverse flow through the affected loop, flow will indicate approximately 30%.

C. Incorrect. First part is correct. Second part is incorrect. Flow will stabilize at approximately 30%.

D. Correct. Both parts correct. The reactor will trip and RCS flow, due to reverse flow, will indicate approximately 30%.

A large break LOCA has occurred RCS pressure is 25 psig Reactor Trip and Safety Injection have actuated All Centrifugal Charging Pumps have failed Safety Injection Pumps and Residual Heat Removal Pumps are running How significant is reflux cooling in removing heat from the core for the current plant conditions?

A. Reflux cooling is minimal. Core heat is removed by Safety Injection water flowing out the break to the containment sump and eventually recirculated.

B. Reflux cooling is minimal. Safety injection pumps will provide enough volume to maintain the core covered, and heat will be removed using natural circulation and steam dumps.

C. Reflux cooling is significant. Without high pressure injection via the charging pumps, steam generator U-tubes will eventually void, stopping Natural Circulation.

D. Reflux cooling is significant. Coolant is boiled in the core, with the steam condensing in the Steam Generator tubes, flowing back to the core through the Hot Legs.

Proposed Answer: A.

Reflux cooling is minimal. Core heat is removed by Safety Injection water flowing out the break to the containment sump and eventually recirculated Explanation:

A. Correct. On a LBLOCA, the RCS rapidly depressurizes to containment pressure. The large injection and leak flow rates remove core decay heat. SG pressures are higher than RCS pressure. Reflux cooling is insignificant.

B. Incorrect. On a LBLOCA the RCS blows down and the SG tubes are voided. Natural circulation is not available. Plausible because reflux cooling is minimal, and ECCS pumps and accumulators will eventually refill and reflood the core.

C. Incorrect. Reflux cooling is insignificant on a LBLOCA. Plausible because on a Small Break LOCA without high pressure injection, natural circulation will be interrupted when SG tubes void, making reflux more important.

D. Incorrect. Reflux cooling is insignificant on a LBLOCA. Plausible because the description of reflux cooling is correct.

2) placing the AUTO/MANUAL controller in MANUAL and using the increase/decrease pushbuttons on VB3 Proposed Answer: C. 1) closed 2) using the Cut-in toggle switch and the OPEN/CLOSE switch on VB3 Explanation:

A. Incorrect. First part incorrect, the valves fail closed. Second part correct.

B. Incorrect. The valves fail closed, not open. Operation must use the toggle switch, not the controller.

C. Correct. The loss of instrument air and nitrogen causes the valve to fail closed. Restoration of the 10% steam dumps is by cutting in backup air using the Cut In toggle switch. Backup air is supplied thru the cut-in switch and then controlled using the open/close switch on VB3. The controller is no longer part of the circuit.

Reactor startup in progress

Reactor is critical in the intermediate range at 1x10-5 amps.

Intermediate Range channel N36 loses control power and fails low.

What is the effect on the reactor startup?

A. Delayed, the reactor remains critical, however, both Source Ranges are energized.

B. Delayed, the reactor remains critical, however, one Intermediate Range High Flux bistable has tripped.

C.

Terminated, because the reactor has tripped because one Intermediate Range High Flux bistable has tripped.

D. Terminated, because the reactor has tripped due to the P-6 Permissive clearing and energizing the Source Range channels above the Source Range High Flux trip setpoint.

Proposed Answer: C. Terminated because the reactor has tripped due to the Intermediate Range High Flux trip bistable de-energized.

Explanation:

A. Incorrect. The reactor has tripped. P-6 will not have actuated and energized the source ranges.

B. Incorrect. The reactor will be tripped. One high flux bistable will be tripped, but the coincidence is 1/2. Trip coincidence could be confused with P-6 energizing the Source Ranges coincidence 2/2.

C. Correct. when the IR loses control power, the High Flux trip (1 of 2) will cause the reactor to trip.

A. Initiation of RCS feed and bleed.

B. Starting RCPs in available RCS loops.

C. Establishing high head ECCS injection.

D. Rapidly depressurizing steam generators.

Proposed Answer: C.

Establishing high head ECCS injection Explanation:

A. Incorrect. This is the method used in EOP FR-H.1 - as a last resort.

B. Incorrect. Starting RCPs is a temporary method to core until some form of flow can be established.

C. Correct. IAW the background document: Reinitiation of high pressure safety injection is the most effective method to recover the core and restore adequate core cooling. If some form of high pressure injection cannot be established or is ineffective in restoring adequate core cooling, then the operator must take actions to reduce the RCS pressure in order for the SI accumulators and low-head SI pumps to inject. Analyses have shown that a rapid secondary depressurization is the most effective means for achieving this. If secondary depressurization is not possible, or primary-to-secondary heat transfer is significantly degraded, and at least one idle SG is available, then the operator must start the RCP(s) associated with the available idle SG(s). The RCPs will provide forced two phase flow through the core and temporarily improve core cooling until some form of make-up flow to the RCS can be established.

D. Incorrect. Depressurization of the RCS to establish low head injection flow (and inject accumulators is the preferred method of heat removal if high head injection cannot be established).

A. RCS Tave B. RCS subcooling C. Pressurizer level D. Pressurizer pressure Proposed Answer: A.

RCS Tave Explanation:

Questions tests the guidelines in OP1.DC10 for monitoring the reactivity control.

Monitoring Key Parameters:

• POWER - Reactivity control is of paramount importance. Reactor power could be changed by actions taken in the RCS - such as boration or dilution - or by a very limited number of primary side problems (rod misalignment, for example). Reactor power could also be changed by changes in secondary power or efficiency. In support of cause and effect, power can be thought of as reactor power, or secondary power - but in essence it is the comparison between power produced in the reactor, and power removed by the secondary. Changes in either the primary or secondary always result in changes to Tave. Unintentional power changes must be immediately addressed.

• TEMPERATURE - Changes to Tave only occur because of changes to the thermodynamic balance of the plant (i.e., the power produced by the reactor is different than the power removed by the secondary plant). Tave changes always result in changes to the density of the RCS fluid inventory. Significant changes in density (Larger Tave changes) always result in changes to PZR level. Unintentional Tave changes require an understanding of POWER before proper action can be taken to stabilize the plant.

By quickly reviewing reactor and secondary power indications, then RCS Tave, then PZR level, then PZR pressure, then primary and secondary flow rates, a mental model (or image) of the true plant condition can be determined. If a key parameter alarms, simply reviewing the key parameters can help determine if the cause of the alarm can be attributed to the alarming parameter, or if the parameter transient is merely an effect of a higher priority parameter transient.

• When a plant transient occurs, the key parameters are quickly and frequently checked to ensure that proper system response is occurring. Provided that all systems are responding appropriately, no operator action would be required to essentially stabilize the plant.

Stabilizing the highest priority parameter that is not stable aids in stabilizing all the lesser priority parameters (i.e., until power is stabilized, Tave cannot be stabilized. Until Tave is stabilized, PZR level cannot be stabilized, etc.).

DCPP L181 Exam Rev 2 A. Correct the next parameter is RCS Tave.

B. Incorrect.. Plausible because Subcooling is a key parameter checked in EOPs for verification of sufficient core cooling. However, it is not part of the PTLPF model C. Incorrect level is checked after RCS Tave.

D. Incorrect. Pressurizer pressure is checked after Pressurizer level.

3. Shift Manager review and approval of the discharge permit A. 2 only B. 1 and 2 C. 3 only D. 1 and 3 Proposed Answer: B. 1 and 2 Explanation:

Although there is no valve indication (lights will be out), full flow from the pump will be supplying all four steam generators.

B. Incorrect. The valves will be fully open due to the loss of 480 VAC power and will have to locally throttled when heat sink is greater than 16%.

C. Incorrect. FCV-95 is DC powered. Loss of DC bus 1-2 would cause FCV-95 to lose power and Bus G would be de-energized, which causes the LCVs to lose power. However, the DC bus is energized, only the bus is de-energized.

D. Incorrect. The LCVs are powered from bus G but remain open despite the loss of power to

A. To prevent exceeding the NPDES permit.

B. To prevent valve erosion and subsequent excessive leakage past the valves when they are closed.

C. To minimize the probability of a LOCA occurring while the valves are open, limiting the offsite boundary doses.

D. To minimize the probability the valves will not fully close when the purge is secured, resulting in a breach of Containment integrity.

Proposed Answer: C. To minimize the probability of a LOCA occurring while the valves are open, limiting the offsite boundary doses.

Explanation:

A. Incorrect. The NPDES covers releases to the environment, but releases to the ocean, not from Containment.

B. Incorrect. These butterfly valves are not fully open (limited to 50 degrees of travel), so its plausible that there is concern of wear.

C. Correct.Containment purges rely on RM-44A and 44B to be OPERABLE. These are process rad monitors. Their operation is assumed to close the purge valves that are opened.

Per ECG 23.3, The purging time restriction is meant to minimize the probability of a LOCA while conducting purging operations and thereby limit offsite boundary doses.

D. Incorrect. The valves are limited in travel because these valves have not been qualified to close under accident conditions. Knowing that there is a concern with closing makes this distractor plausible.

A few minutes after performing leak isolation steps, the following conditions exist:

ECCS flow is stable Pressurizer level is 22% and rising slowly RCS pressure is 400 psig and lowering slowly What procedure should be entered next by the Shift Foreman?

A. Go to EOP E-1.1, SI Termination.

B. Go to EOP ECA-1.1, Loss of Emergency Coolant Recirculation.

C. Go to EOP E-1, Loss of Reactor or Secondary Coolant, then go to E-1.1, SI Termination.

D. Go to EOP E-1, Loss of Reactor or Secondary Coolant, then go to E-1.2, Post-LOCA Cooldown Depressurization.

Proposed Answer: B. Go to EOP ECA-1.1, Loss of Emergency Coolant Recirculation Explanation:

To answer this question, the SRO must know and understand the bases which explains what the expected response is if the LOCA is isolated and the appropriate procedure to be entered from ECA-1.2.

A. Incorrect. The bases for ECA-1.2 states: This step instructs the operator to check RCS pressure to determine if the break has been isolated by previous actions. If the break is isolated in Step 2, a significant RCS pressure increase will occur due to the SI flow filling up the RCS with break flow stopped. The operator transfers to E-1, LOSS OF REACTOR OR SECONDARY COOLANT, if the break has been isolated, for further recovery actions.

If the break has not been isolated, the operator is sent to ECA-1.1, LOSS OF EMERGENCY COOLANT RECIRCULATION, for further recovery actions since there will be no inventory in the sump. However, going to E-1.1 is plausible because if the break is/was isolated, as they would do for a leak while in E-1.

B. Correct. Because pressure has not responded, the break is not isolated, ECA-1.1 is the appropriate procedure. The objective of the loss of ECR guideline is threefold: 1) to continue attempts to restore emergency coolant recirculation capability, 2) to delay depletion of the RWST by adding makeup fluid and reducing outflow, and 3) to depressurize the RCS to minimize break flow and cause SI accumulator injection.

C. Incorrect. The break is not isolated. The operator transfers to E-1, LOSS OF REACTOR OR SECONDARY COOLANT, if the break has been isolated, for further recovery actions and then to E-1.1 if there are no other complications. If the break has not been isolated, the operator is sent to ECA-1.1, LOSS OF EMERGENCY COOLANT RECIRCULATION,

DCPP L181 Exam Rev 2 for further recovery actions since there will be no inventory in the sump.

D. Incorrect. The break is not isolated, therefore a transition to E-1 is not correct. However, if its thought the break is not isolated and the course of action is the same as a small RCS break, then the transition to E-1.2 would plausible.
