- 1. 001 001/BOTH/OK/NEW/NEW/000008 AK2.01/2.7/2.7/H/2Given the following conditions on Unit 2:
- The crew is responding to a Reactor Trip and has transitioned to2-OHP-4023-ES-0.1, Reactor Trip Response, from 2-OHP-4023-E-0, Reactor Trip orSafety Injection.
- Following the transition the crew notes the following conditions: o RCS Pressure is 2100 psig and lowering o 2-NRV-152, indicating lights show an intermediate positionWhich ONE of the following describes the actions the operator should take to addressthese conditions: Close 2-NMO-152, PORV Block Valve, to stop discharge into the PRT.Open Pressurizer Spray valves to depressurize the RCS and limit the loss ofReactor Coolant.
Turn on all Pressurizer Heaters to maintain RCS pressure.Isolate air to containment to fail the Pressurizer PORV closed and stop the RCSmass loss.A.B.C.D.ANSWER: AA - CORRECT. Block valve is in series with the Pressurizer PORV. Closing theblock valve will isolate the leak and prevent further depressurizationof the RCS.B - INCORRECT. Mass loss is occurring. Need to isolate the leak by isolating thePORV. Mass loss will continue as long as there is pressure in theRCS and the PORV is leaking.C - INCORRECT. It is highly unlikely that the heaters can maintain pressure with astuck open Pressurizer PORV. Additionally, even if the heaterscould stabilize/raise pressure, the RCS leak would still persist.D - INCORRECT. NRV-152 has Nitrogen Backup supply, so isolating air tocontainment will not force the PORV to fail closed.

- A reactor trip and safety injection have occurred.
- The crew is responding to a Small Break Loss of Coolant Accident (LOCA).
- All Reactor Coolant Pumps are tripped.
- The crew is depressurizing the Reactor Coolant System (RCS) in accordance withStep 13 of 2-OHP-4023-ES-1.2, Post LOCA Cooldown and Depressurization.
- A PORV is being used to depressurize the RCS.As the depressurization occurs, which one of the following describes the expectedtrend of pressurizer level and the adverse operating condition that may initially occur asa result? Lowering Pressurizer Level; Uncovering Pressurizer heaters.
Rising Pressurizer Level; Water solid conditions in the RCS and Pressurizer.
Rising Pressurizer Level; Upper head region voiding may occur.
Lowering Pressurizer Level; Upper head region voiding may occur. A.B.C.D.ANSWER: CA - INCORRECT. Pressurizer will rise during depressurization versus lower. It isplausible that if the operator does not understand this concept andthey believe Pressurizer level will drop that the heaters wouldbecome uncovered which is an undesirable condition. B - INCORRECT. Although it is correct that Pressurizer level will rise and it is plausiblethat eventually the Pressurizer would go solid, that this would notINITIALLY occur.C - CORRECT. The caution prior to commencing depressurization in ES-1.2 to refillthe Pressurizer, states that a head void may occur as indicated by arising Pressurizer level as water in transferred from the RCS to thePressurizer.D - INCORRECT. Pressurizer level will rise vs. lower. The reason is plausible andtests whether the student correctly understands the importantconcept.

- Unit tripped from 29% power.
- RCP 21 breaker tripped open when the busses swapped.Which one of the following describes the response of Thot and Tcold in Loop 1?Tcold rises to approximately equal Thot.
Thot lowers to approximately equal Tcold.
Tcold lowers, Thot remains approximately stable.
Thot rises, Tcold remains approximately stable.A.B.C.D.ANSWER: B A - INCORRECT. Tcold remains approximately the same, at low power nearsaturation for SG. Plausible due to lack of forced circulationprevents S/G from transferring heat to Main Steam Headerassuming normal RCS flow direction, so RCS loop heats up to ThotB - CORRECT. Loss of RCS flow in 1 loop, reverse flow in that loop will cause Thotto drop (no more forced circulation in that loop) to the Tcold value orslightly below. C - INCORRECT. Tcold remains approximately the same, at low power nearsaturation for SG. Thot lowers since the core exit flow is not forcedinto the loop. Plausible due to reverse flow in RCS loop, from loss ofRCP, allows Tcold to enter Steam Generator which removedadditional energy thus lowering Tcold additionally.D - INCORRECT. Thot lowers since the core exit flow is not forced into the loop.Plausible due to the Turbine Steam Demand did not change sooverall Reactor Power will remain constant so the core will producethe same power from the remaining Steam Generators. Assumingthe student believes normal RCS flowpath (at a reduced rate withno forced circulation) and if Tcold remains the same the onlymethod to increase power from the remaining Steam Generators isto increase Thot.

- Reactor Coolant System (RCS) is in mid-loop condition* The following indications are fluctuating on the running Residual Heat Removal(RHR): amps, flow, and discharge pressureWhich ONE of the following statements is correct regarding the standby RHR pump? The standby RHR Pump should:NOT be immediately started because air entrainment could cause a loss of bothRHR trains.
be immediately started because following a loss of RHR flow, an RCSpressurization may occur precluding gravity feed makeup. be immediately started because under certain loss of RHR conditions, coreuncovery or core voiding can occur within 15 to 20 minutes.NOT be immediately started because starting an idle RHR pump under mid-loopconditions could cause an unacceptable reduction in reactor shutdown margin.A.B.C.D.ANSWER: AA - CORRECT. The ARG provides a clear guidance which includes industryexperience of why operation of an RHR pump operating with airentrapment should be evaluated because it could lead to pumpdamage. Starting the other RHR pump could transfer the problem tothe other pump leading to a complete loss of the system. B - INCORRECT. Plausible because gravity makeup is a required action but startingthe RHR pump is not an option immediately. C - INCORRECT. While it is plausible that core uncovery or voiding could occur in arelatively short period of time, it is not correct that the RHR pump bestarted in this plant condition. D - INCORRECT. Although it is correct that the pump should not be started it is notcorrect that SDM would be affected in this condition since it wasalready verified procedurally to meet TS plant conditions. Plausiblesince SDM is a concern during cooldown & RHR flow helps ensureproper mixing & SDM.

- The operators are implementing 2-OHP-4023-FR-S.1, Response to Nuclear PowerGeneration/ATWS
- Both Reactor Trip Breakers remain closed.
- The operators have completed steps of 2-OHP-4023-FR-S.1 through opening theMG Set output Breakers to shutdown the reactor.Which ONE of the following describes the impact and potential consequences of theReactor Trip Breakers remaining closed?main steam line isolation signal will NOT occur to prevent excessive reactivityduring the trip due to rapid RCS cooldown.
feedwater isolation signal will NOT actuate to prevent excessive reactor coolantsystem cooldown from the overfeeding of the steam generators.main generator trip signal will NOT be generated preventing transfer of busses toreserve feed.
feedwater flow conservation signal will NOT occur to ensure equal distribution ofwater to the steam generators.A.B.C.D.ANSWER: BA - INCORRECT. Main steam line isolation does not depend on the status of theReactor Trip Breakers. This signal will occur as designed onappropriate containment pressure or SG parameters.B - CORRECT. P-4 (Rx Trip Breaker Position) feeds the feedwater isolation signal. Either breaker being open will cause an isolation of flow to the SGs. However with neither breaker open, all FMOs and FRVs will remainopen and Main Feedpumps will not trip. This will cause excessiveflow to the SGs, which could lead to an overcooling of the RCS.C - INCORRECT. Main Generator trip is caused by a sensed Turbine Trip (All TurbineSteam Valves Closed). There is no interlock between the ReactorTrip Breakers and the generator trip. D - INCORRECT. Flow conservation is often confused with feedwater isolation. Flowconservation will start the Aux Feedwater Pumps and open the AFWPump discharge valves. There is no interlock between the ReactorTrip Breakers and Flow Conservation.

- Main Turbine DCS is in "MW IN" in preparation for turbine valve testing.
- Condenser vacuum is lowering.Assuming no action has been taken by the crew, which ONE of the following describesthe response of the rod control system to this event? Control rods will automatically: insert due to the rise in Tavg from the rise in steam flow.insert due to the rise in Tavg from the lowering in steam flow.withdraw due to the drop in Tavg from the rise in steam flow.withdraw due to the a drop in Tavg from the lowering steam flow.A.B.C.D.ANSWER: CA - INCORRECT. Controls rods will withdraw. See Answer C. Plausible since duringnormal power escalations Tavg and Steam flow both rise.B - INCORRECT. Controls rods will withdraw. See Answer C. Plausible due to designof system to insert rods on rising Tavg.C - CORRECT. With the Main Turbine in "MW IN" control, the turbine valves areallowed to reposition to try to maintain Main Generator Load. Asvacuum lowers, the turbine will become less efficient, causing moresteam flow for the same MW output. As steam flow rises, RCS Tavewill lower below Tref. With rods in AUTO, the rods will withdraw tominimize the Tave-Tref deviation. D - INCORRECT. Steam flow will rise. See Answer C.

- Required actions per 2-OHP-4022-013-011, Containment InstrumentationMalfunction, have been completed.
- Required Technical Specification Actions have been taken for Channel #1,2-PPP-303.Which ONE of the following describes the SI and CTS, and Containment IsolationPhase A (CIA) and B (CIB) response to a subsequent failure of CRID 4 power supply. SI CTS CIA CIB ACTUATES ACTUATES ACTUATES ACTUATES YES NO YES NO YES YES YES YES NO YES NO YES NO NO NO NOA.B.C.D.ANSWER: D A - INCORRECT. See explanation Below.B - INCORRECT. See explanation Below.
C - INCORRECT. See explanation Below.
D - CORRECT. See explanation Below.
The CTS Actuation Bistable is placed in the BYPASSED condition to preventinadvertent actuation. This changes the remaining channel coincidence to 2/3 insteadof the previous 2/4. Only 3 channels (Channels 2, 3, & 4) feed the SI Actuation. Thebistable for the CTS actuation is placed in the BYPASS condition, making the CTS a2/3 coincidence for the remaining channels (2, 3, and 4). CRID 4 failure will NOT meetthe 2/3 co-incidence for either the SI or CIA. CTS/CIB still required 2/3 to actuate,therefore only one channel will not cause the CTS/CIB. The logic between CTS andCIB is always the same which prevents the student from eliminating distractors basedon obvious distractors; this same logic applies to SI and CIA. This forces the student tohave a full understanding of the question in order to answer the question correctly.

Whileattempting to restore feed flow to a SG in accordance with OHP-4023-FR-H.1,Response to Loss of Secondary Heat Sink, conditions degrade to the point that RCSbleed-and-feed must be established.
Under these conditions, RCS bleed-and-feed must be established expeditiously to:prevent a loss of secondary heat sink.
minimize core uncovery and prevent inadequate core cooling. prevent an overpressurization challenge to the reactor vessel. prevent a rapid RCS overpressurization, followed by a rapid RCS depressurizationdue to RCP seal failure.A.B.C.D.ANSWER: BA - INCORRECT. Attempts to restore the heat sink have been unsuccessful. Bleed-and-feed is established to raise the amount of injection flowinto the core and thus minimize the core uncovery. Plausible basedon the purpose of the FRP being used. The goal is to establish andthus prevent a loss of secondary heat sink.B - CORRECT. If the operator cannot restore feedwater flow to the SGs, conditionswill degrade to the point where RCS bleed and feed must beestablished to minimize core uncovery and prevent inadequate corecooling.C - INCORRECT. Based on the FRGs, even if overpressurization were a concern, thepriority of core cooling is higher than PTS concerns. Plausiblebased on the event if no actions were taken the RCS wouldincrease in pressure based on the lack of heat removal from theRCS.D - INCORRECT. Core cooling is the second highest priority in the EOPs(Subcriticality being the highest). Any other concern would be of alower priority than establishing core cooling of some nature, in thiscase bleed-and-feed. Plausible based on the conditions describeddo not state the basis for requiring feed and bleed (the conditionscould be caused by high RCS pressure) and the conditions couldalso exist without any Charging pumps running thus challenging theRCP seals.

- Reactor power was 100% power when an RCS leak developed.
- The Unit Supervisor is implementing 2-OHP 4022-002-020, Excessive RCSLeakage.The following conditions now exist:
- Letdown flow is isolated.
- East and West Charging pumps are operating.
- Charging flow is 180 gpm.
- Pressurizer level is 51% and constant.
- VCT makeup is in Auto.
- VCT level is 22% and lowering.

Page 150 of 198 Test Date: 7/2/2010 Cook 2010 NRC Examination ANSWER: D A - INCORRECT. The procedure directs a Reactor Trip. Temperature control wouldbe extremely difficult. The VCT Refueling Water SequenceActuation and alarm come in at 2.5% VCT level. Plausible sinceVCT low alarm setpoint is 14.0% and RWST alignment wouldimpact temperature control.B - INCORRECT. Letdown was isolated to allow Pressurizer level to be stabilized.Auto Makeup will start at 24% but flow will not be sufficient to makeup for 180 gpm leak. C - INCORRECT. The procedure directs a Reactor Trip. The VCT Refueling WaterSequence Actuation and alarm come in at 2.5% VCT level.Plausible since a VCT low alarm setpoint is at 7.0% and thisleakage would exceed TS.D - CORRECT. Leakage in excess of VCT makeup will lead to eventual loss of CCPsuction. This would be mitigated by the refueling water sequenceswapover to the RWST suction source but this would result inexcessive boration of the RCS. Lowering level in excess of automakeup capability require a RX trip per 2-OHP-4022-002-020.

- A reactor startup is in progress with the reactor just critical.
- The operator has just stopped moving control rods.
- Intermediate Range Power slowly rises above 2 x 10-10 amps.
- ONE source range (SR) nuclear instrumentation channel (N-31) fails LOW.
- Remaining power indications stabilize. Which ONE of the following actions, if any, is required for compliance with TechnicalSpecifications?
Reference Provided: Unit 2 TS 3.3.1, Reactor Trip System InstrumentationNo action required, source range not required to be operable.
Trip the reactor and enter 2-OHP-4023-E-0, Reactor Trip or Safety Injection. Conduct a reactor shutdown and restore both SR channels to operability prior tonext startup.
Suspend all operations involving positive reactivity changes until both SR channelsare restored to operability. A.B.C.D.ANSWER: A A - CORRECT. TS 3.3.1 (Instrumentation) establishes that above P-6, the SR NIare not required by TS and will shortly be de-energized byprocedure. Since there are no TS implications, the startup mayproceed.B - INCORRECT. No entry conditions are met for a reactor trip. (plausiblemisconception) Plausible as this would be a conservative action toplace the plant in a known safe, stable condition but does notanswer the actual question.C - INCORRECT. A plant shutdown is not required unless both SR channels are lostduring reactor startup. Plausible since shutdown is performed forseveral startup inconsistencies (ECC wrong, conditions change,etc.) and this is an action for several reactor start up issues.D - INCORRECT. SR channels can be blocked. Reactor power is above P-6.Plausible since this statement would be correct if reactor power was< P-6 and this is an action associated with the Source RangeDetectors in Technical Specifications.

Studentmust know this temperature is above the trip setpoint.B - CORRECT. 1-OHP-4022-016-001, Caution prior to Step 1 states that theaffected RCP must be removed from service by performing Step 17if motor bearing temperatures exceed 200 oF. Step 17 andassociated note states that the order is to Trip the Reactor, go toE-0, verify reactor trip, then trip the AFFECTED RCP.C- INCORRECT. Loss of CCW requires trip of Reactor and ALL RCPs, but CCWMalfunction only requires tripping the AFFECTED RCP (RCP #13with the temperature >200 oF). Plausible as all actions are correctexcept stopping all RCP's. This is incorrect and will complicate themitigation strategy of the EOPS but is a fairly routine activity in thesimulator for the students to stop all RCP's vs. just stopping oneRCP.D - INCORRECT.

Which ONE of the following describes the required Pressurizer level and why?20% because the Containment Radiation levels are no longer above the Adversesetpoint requirement.
24% because adverse values must be used until evaluated for lasting effectsbecause the integrated dose limit has been exceeded.24% because adverse containment exists due to the current containment radiationdose rate.
20% because the Containment Pressure is no longer above the Adverse setpointrequirementA.B.C.D. Page 191 of 198 Test Date: 7/2/2010 Cook 2010 NRC Examination ANSWER: B A - INCORRECT. The integrated dose is (1,015,000 R) which is greater than 10 6 R, soadverse containment values must be used. Plausible as the instantvalues for dose do not require the use of Adverse numbersB - CORRECT. Adverse containment values are required to be used whencontainment pressure is >5 psig or >105 R/Hr. When pressurelowers to <5 psig normal values may be used as long as theintegrated dose is <10 6 R. The integrated dose is (1,015,000 R)which is greater than 10 6 R, so adverse containment values must beused.C - INCORRECT. The current Dose Rate is <105 R/Hr. Plausible as the instant valuefor Containment pressure is close to the adverse setpointD - INCORRECT. Pressure is <5 psig. Plausible as the instant value for containmentpressure is close to the adverse setpoint.LESSON PLAN/OBJ: RO-C-EOP01/#8 & #9

Limitations on specific activity in the RCS reduces corrosion product activation andsubsequent RCS integrity challenge.
During a LOCA the dose will NOT exceed the 10CFR20 limits at the site boundary.During a steam generator tube rupture the release of activity through theatmospheric relief valves will NOT exceed 10CFR100 limits.A.B.C.D.ANSWER: DA - INCORRECT. See Answer D. Plausible as this is a concern during refuelingevolutions for dose to employees moving fuel.B - INCORRECT. See Answer D. Plausible as this identifies a challenge to corrosionaffecting the metal in the RCS for long term RCS operation.C - INCORRECT. See Answer D. Plausible for accident dose concerns but the CFRreference is in correct.D - CORRECT. The maximum dose to the whole body and the thyroid that anindividual at the site boundary can receive for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> during anaccident is specified in 10 CFR 100 (Ref. 1). The limits on specificactivity ensure that the doses are held to a small fraction of the 10CFR 100 limits during analyzed transients and accidents.The RCS specific activity LCO limits the allowable concentrationlevel of radionuclides in the reactor coolant. The LCO limits areestablished to minimize the offsite radioactivity dose consequencesin the event of a steam generator tube rupture (SGTR) accident.
