Explanation:
load reject A load reject signal at any reactor power level will cause a turbine control valve fast closure scram. The load reject signal does not input into the turbine stop valve closure scram logic. During During a loss of offsite power, if the grid is lost all PCBs are opened per OAOP-36.1. OAOP-36. 1.
Distractor Analysis:
Choice A: Correct answer, see explanation Choice B: Incorrect Load reject initiates a TCV fast closure scram not a TSV. A misconception of the difference between TCV and TSV scrams may cause a student to select this answer.
Choice C: Incorrect. OAOP-22 does not have an action for loss of grid only for degraded.
Choice D: Incorrect. Load reject initiates a TCV fast closure scram not a TSV. A misconception of the difference between TCV and TSV scrams may cause a student to select this answer. OAOP-22 does not have an action for loss of grid only for degraded.

AOP-5 does have a step to isolate the system that is leaking, but SCCP overrides that if the system is required by EOPs. WithWith the AATWS TWS the RCIC system is required for alternate boron injection. The Suppression Pool level is high but this will only transfer the HPCI suction valves as RCIC only transfers on CST level. LEP-03 would first want to use CRD then RCIC as long as suction is from CST.
Distractor Analysis:
Choice A: Plausible because AOP-5 does have a step to isolate the system that is leaking, but SCCP overrides that if the system is required by EOPs.
Choice B: Plausible because the high suppression pool level would transfer HPCI and SEP-10 has a section for transferring the suction to the CST from the Suppression Pool.
Choice C: Correct answer, see explanation Choice D: Plausible becasue LPC does have a step for terminating and preventing but this does not address RCIC.

With a LOOP present and no actions taken to restore Off-site power (not provided in the question), the only available means of decay heat removal is alternate shutdown cooling utilizing SRVs.

Choice A: Plausible because 200 inches is correct and OP-17 contains actions for using FPC and SSFPC, but these would only be available if the reactor head is removed and fuel pool gates removed.
Choice B: Correct Answer Choice C: Plausible because 254 inches is the level of the MSLs and could be confused with Natural Circulation level due to the requirement to be at this level during alternate SDC and OP-17 contains actions for using FPC and SSFPC, but these would only be available if the reactor head is removed and fuel pool gates removed.

High Cog Level: High Explanation:
OAOP-05 immediate action for a dropped or damaged fuel assembly is to ENSURE CREVS is in OAOP-OS operation.
The dose consequence calculation for the fuel handling accident does not credit the secondary containment or automatic CREVS start, however, it does assume that CREVS is manually initiated within 20 minutes of a dropped/damaged fuel assembly. Based on this analysis, Technical Specifications do not require secondary containment or CREVS automatic initiation instrumentation except during Modes 1, 2, or 3 or during operations with the potential to drain the Reactor vessel. The CREV System is designed to maintain a habitable environment in the CRE for a 30 day continuous occupancy after a DBA without exceeding S 5 rem total effective dose equivalent (TEDE).

A A spill spill of of highly highly radioactive solid radioactive solid materials materials such such as as spent spent resin, resin, filter filter sludge, sludge, neutron neutron sources, sources, oror irradiated reactor internal irradiated internal components may create aa serious personnel personnel exposure problem and should be handled with extreme caution. In addition, addition, high high radiation high airborne acUvity and higl1 activity may accompany aa spill.
High airborne High airborne activity may occur activity may occur from reactor reactor coolant coolant leaks, leaks, coolant coolant spills, radwaste leal,s, radwaste leaks, sampling, grinding, draining, draining, and other maintenance.

levels may be caused High radiation [evels caused by radiation "streaming,"
streaming, loss of or degraded element damage, high airi)orne shielding, fuel element airborne activity, coolant spillS, spills, or radiography.
New or spent fuel damage may occur within the plant during fuel handling operations. Fuel may be damaged if it is inadvertently dropped oral[owed or allowed to collide with objects. Damage may also be sustained if heavy objects (shipping casks, reactor vessel head, dlY'Nell drywell head, etc.) are allowed to fall on the fuel. These accidents may release a substantial amount of radioactive noble gases, halogens, and other fission products into the secondary containmentcontainment. The secondary containment will be automatically isolated due to high radiation at its ventilation exhaust plenum. Although Standby Gas Treatment (SBGT) System will reduce the activity released to the environs, there is a activir; a chance that technical speCification specification limits may be exceeded.
The dose consequence calculation for the fuel handling accident does not credit the secondary containment or automatic CREVS start, however, it does assume that CREVS is manually initiated within 20 minutes of a droppedfdamageddropped(damaged fuel assembly. Based on this analysis, Technical Specifications do not require secondary containment or CREVS automatic initiation instrumentation except during Modes 1, 1, 2, or 33 or during operations with the potential to drain the Reactor vessel.

Explanation:
Reduced OW Reduced DW cooling or rising DW DW temperature results in in DW pressure increases increases whose severity is dependent upon plant conditions. OAOP-14.0, Abnormal Primary Containment Conditions provides guidance on indications to be monitored and actions to be taken which include verification of cooling system lineups and reductions in power to maintain average temperature below 150°F. Failure to accomplish this may require entry into the OEOP-02-PCCP Primary Containment Control.
Elevated DW temperature causes DW pressure to rise. As DW pressure rises, SP water level rises causing a rise in SP pressure. Due to the downcomers extending 3 feet below the surface of the SP water level a differential pressure will always exist. Temperature response is different from LOCA response due to steam AND non-condensibles being forced into the SP - steam condensing and-non-condensibles collecting in SP air space.

Distractor Analysis:
Choice A: Plausible because SP pressure is changed by the change in SP level only vs pressure, steam, and non-condensibles during a LOCA. The SP air space temperature is in equilibrium with SP water temperature (95°Fmax during normal operations) rising DW pressure would have a direct impact on SP level. However during temperature only (no steam), the DW pressure increase is cushioned by SP water, small changes in SP water level provides small change in SP pressure.

pumped. Very high lube oil temperatures can result in loss of lubricating qualities in the oil and thus cause damage to the bearings. Suction for HPCI and RCIC is aligned to the Condensate Sto(age Storage Tank (CST) if it is available. The HPCI automatic suction transfer logic can be defeated to allow this lineup if necessary provided suppression pool temperature is approaching 140°F.
Distractor Analysis:
Choice A: Plausible because reducing flow would be a correct action if HPCI NPSH was the concern. At high temperatures with low level in the torus this could be a correct action. Pump bearing damage is a correct statement.
Choice B: Plausible because reducing flow would be a correct action if HPCI NPSH was the concern. At high temperatures with low level in the torus this could be a correct action. a loss of NPSH would be correct for the reason to reduce flow.

Cog Level: High High Explanation:
The air dryer malfunction has caused air pressure to lower. The Service Air low pressure alarms comes in at 107 psig. At 105# decreasing the Service Air system isolates, thus the 0 psig indication on Service Air.
The alarms for the receivers low pressure come in at 95# and are located in the Reactor Building. With these alarms in the operators are required to close the BFIVs while there is still sufficient air pressure remaining to make the secondary containment isolation valves close in accordance with the AOP supplemental actions.
supplemental Distractor Analysis:
Choice A: Correct answer; The air dryer bypass valve opens at 98# and dropping and the steps are in the AOP for closing the BFIVs.
Choice B: Plausible because the air dryer bypass valve is open, but the guidance for closure of the BFIVs is contained in the AOP or RB INSTR INS TRAIRAIR RECEIVER 2A(B) PRESS LOW LOWAPP.

Choice C: Plausible because the AOP is the correct procedure for closure of the BFIVs, but the air dryer bypass valve would be open (requires system knowledge to know the setpoint for the bypass opening).

Distractor Analysis:
Choice A: Plausible because if the valve is de-energized in its intended state (such as a PC IV in the PCIV closed dierection) this could be considered correct although for this case the open direction for this normally closed valve would have to have interlocks defeated to have both the F015 and F017 both open (potential to pressurize low pressure piping). OAP-025 is correct.
Choice B: Plausible because if the valve is de-energized in its intended state (such as a PCIV in the closed dierection) this could be considered correct although for this case the open direction for this normally closed valve would have to have interlocks defeated to have both the F015 and F017 both open (potential to pressurize low pressure piping). 001-01.08 001-01 .08 no longer provides guidance for evaluating MRIPSA MR/PSA system availability.

Explanation:
Provide ENP-24-12, Provide ENP-24-12, Figure Figure 11 as a reference reference From FH-11, 4.37 To help ensure that an unmonitored criticality will not occur, control rod withdrawal is not allowed during the core reload sequence until a neutronic bridge is established. The neutronic bridge ensures that two SRMs are neutronically coupled, thus monitoring the loaded area of the core. The reload sequence has three basic steps. Four fuel bundles are loaded around each of the four SRMs, the neutronic bridge is established and a spiral reload of the other fuel bundles completes the sequence. The neutronic bridge is established by loading fuel in all fuel cells in a line between two SRMs. These SRMs must be on opposite sides of the core and the line of loaded fuel cells must intersect the center of the core (A to D would not intersect the center, B to D would).
Distractor Analysis:
Choice A: Plausible because loading fuel around 2 SRMs and a line between them would establish a neutron bridge (between those 2 SRMs)SRM5) but not lAW PAW OFH-11 OFH-1 1 and A&D are adjacent.
Choice B: Plausible because loading fuel around 2 SRMs and a line between them would establish a neutron bridge (between those 2 SRM5) JAW OFH-1 SRMs) but not lAW OFH-11I and A&D are adjacent.
Choice C: Plausible because loading fuel around all SRMs is correct but A&D are adjacent.
Choice D: Correct Answer SRO Only Basis: IOCFR55.43.6 10CFR55.43.6 Procedures and limitations involved in initial core loading, alterations in core configuration, control rod programming, and determination of various internal and external effects on core reactivity.

Explanation:
Valves fail closed on loss of DC DC power or Pneumatics, however with a loss loss of power, position indication on P601 will also be lost. Per APP A-03, 3-5 -IfIf either E51-F025 or E51-F026 has been failed closed for more than 5 minutes, perform the following:
- a. Close Turbine Trip and Throttle Valve, E51-V8, E51 -V8, to prevent water hammer damage from a RCIC auto start.
this would still make RCIC available for use per the procedure but it is inoperable because it will not auto start as required.
This will make the RCIC system inoperable but available to be restarted per the procedure.
Distractor Analysis:
Choice A: Plausible because loss of pneumatics only is correct and the system will not start in auto when required, but could be manually started.
Choice B: Correct Answer Choice C: Plausible because a loss of power will cause valves to fail closed, but with loss of power position indication will be lost and the system will not start in auto when required.
Choice D: Plausible because pneumatics and power power will cause valves to to fail closed, but with loss loss of of power power position position indication indication will be be lost and itit is is available available to start per the procedure procedure which makes makes itit available.

The Minimum Number of SRVs Required for Emergency Depressurization Depressurizatiori (5) is defined to be the least number of SRVs which correspond to a Minimum Alternate Reactor Flooding Pressure sufficiently low that the ECCS with the lowest !lead head will be capable of making up the SRV steam flow at the correspondin corresponding g Minimum Alternate Reactor Flooding Pressure.
The Minimum SRV Re-opening Pressure is the lowest reactor pressure at which an an SRV will remain fully open with its control switch in the open position. The accuracy of the re-opening pressure and the indication available to determine detelmine reactor pressure result in conditions such that the SRVs are not always open when the pressure indicated indicated is 50 psig. One hundred hundred psig has has been selected as aa value which can be used used to determine determine the SRV5 SRVs have failed to function. When reactor pressure is below below this value, depressurizat depressurization ion is considered considered complete and reactor pressure reduction need need notnot be be augmented augmented by by use use of of additional additional systems systems even even ifif less less than than the the minimum minimum number number ofof SRVs SRVs are are open.
