In order to answer this question correctly, the applicant must recall the basis for the compensatory measures contained in T.S. 3.1.3.1 Action d.3. for maintaining the reactor at power with a dropped rod. This includes the knowledge that power is limited to 85% as part of compensatory measures.
A. The first part is plausible because power must be reduced and/or maintained less than 75%in accordance with Technical Specification action statements as well as per actions of AOP-403.6 for dropped rod. The second part is correct; Safety analyses affected by rod misalignment must be re-analyzed.
Incorrect because 85% is the correct high flux trip setpoint.
B. CORRECT. The new high flux trip setpoint must be reduced to 85% in accordance with 3.1.3.1.d.3.d) and safety analyses affected by rod misalignment must be re-analyzed as identified in the T.S. 3.1.3.1basis.
C. The first part is plausible because power must be reduced and/or maintained less than 75%
in accordance with Technical Specification action statements as well as per actions of AOP-403.6 for dropped rod. The second part is plausible because verifying rods are above the rod insertion limits are a method of ensuring that hot channel factor limits are maintained between surveillances.
Incorrect because 85% is the correct high flux trip setpoint and safety analyses affected by rod misalignment must be re-analyzed.
D. The first part is correct; The high flux trip setpoint must be reduced to 85%. The second part is plausible because verifying rods are above the rod insertion limits are a method of ensuring that hot channel factor limits are maintained between surveillances Incorrect because safety analyses affected by rod misalignment must be re-analyzed.

NEW for 2013 NRC QUESTION HISTORY:
Rev. 0 submitted by RJ Ops Review: Nick O'Kimosh Approved: 6/17/13 Rick Garner DISTRACTOR ANALYSIS:
In order to answer this question correctly, the applicant must assess plant conditions and determine that conditions are no longer met for termination of safety injection due to indications of leakby on a PZR PORV and select a procedure that will close PORVs to mitigate the event.
A. Plausible because the pressurizer level is at 100% and in the case of only a faulted steam generator, SI termination is implemented as soon as possible to mitigate a high rising pressurizer level. Also plausible because EOP-2.0 checks for SI termination criteria in step 10 and is the correct transition for the current conditions.
Incorrect because SI termination will not be performed under the current conditions.
B. CORRECT. Lowering RCS subcooling and rising PRT pressure indicates that PORVs must be shut to mitigate the event. The correct procedure transition when conditions for SI termination are not met is to EOP-2.0.
C. The first part is correct; Lowering RCS subcooling and rising PRT pressure indicates that PORVs must be shut to mitigate the event. The second part is plausible because the normal transition for a faulted steam generator without other complications is from EOP-3.0 to EOP-1.2 to terminate SI.
Incorrect because conditions are not met for transfer to EOP-1.2.
D. Plausible because the pressurizer level is at 100% and in the case of only a faulted steam generator, SI termination is implemented as soon as possible to mitigate a high rising pressurizer level. The normal procedure transition for a faulted steam generator without other complications is from EOP-3.0 to EOP-1.2 to terminate SI.

QUESTION USAGE MODIFIED FROM RPS 19 QUESTION HISTORY Rev. 0 submitted by RJ Ops Review: Nick O'Kimosh Approved: 6/17/13 Rick Garner DISTRACTOR ANALYSIS In order to answer this question correctly, the applicant must recall that an SI train requires an input of a train-specific open signal from the Reactor Trip and/or Bypass breakers in order to reset or in lieu of that condition, requires resetting of relays in accordance with an SOP. It also requires selection of the correct SOP.
A. CORRECT. The input from open trip breakers is train-specific which will allow resetting one train of SI under the current condition. The procedure that will reset SI relays for the case of a stuck-closed trip breaker is SOP-112, SAFETY INJECTION SYSTEM.
B. Plausible but incorrect. Certain ESF and Reactor Protection functions require operation of 2 out of 2 channels or trains to complete. Examples are blocking of Nuclear Instrument trip signals, unblocking of Low Pressurizer pressure SI and manual actuation of RB Spray.
Incorrect because P-4 input to SI reset is train-specific so one train of SI can be reset.
The second part is correct; The procedure that will reset SI relays for the case of a stuck-closed trip breaker is SOP-112, SAFETY INJECTION SYSTEM.
Incorrect because one train of SI can be reset.
C. The first part is correct in stating that one SI train can be reset. The second part is plausible because SOP-313, LOCAL SWITCHGEAR BREAKER OPERATIONS can be used to rack out Trip and Bypass breaker. Racking the breaker provides an open signal which would make up P-4 via the breaker cell switch (33) contacts. In addition SOP-313 contains a passage to notify I&C to perform surveillances for P-4 OPERABILITY. It should be noted that the breaker is not under load; current through the breaker would not affect plausibility.
Incorrect because SOP-313 is not used to provide a P-4 signal and SOP-313 requires the breaker to be open prior to attempting racking of the breaker..
D. Plausible because certain ESF and Reactor Protection functions require operation of 2 out of 2 channels or trains to complete (see examples above). The second part is plausible; SOP-313, LOCAL SWITCHGEAR BREAKER OPERATIONS can be used to rack Trip and Bypass breaker and racking the breaker provides an open signal remotely although this procedure requires the breaker to be open prior to racking.
Incorrect because one train of SI can be reset and SOP-313 is not the correct procedure selection.

In order to answer this question correctly, the applicant must identify the RCPs that must be stopped in order to stop spray flow through PCV-444D and the procedure in the EOP network that will provide the necessary guidance.
A. Plausible because pressure is lowering toward a Safety Injection (SI) setpoint and EOP-1.0 contains actions to trip "A" RCP for a stuck open spray valve. Additionally, the candidate may think that actuation of a Phase A isolation and securing air to the RB may close the spray valve.
Incorrect because early actuation of a SI is not allowed and implementation of EOP-1.1 would trip "A" RCP without a SI actuated.
B. Plausible because pressure is lowering toward a Safety Injection (SI) setpoint and EOP-1.0 contains actions to trip "A" RCP for a stuck open spray valve. Additionally, the candidate may think that actuation of a Phase A isolation and securing air to the RB may close the spray valve.
Incorrect because early actuation of a SI is not allowed and implementation of EOP-1.1 would trip "A" RCP without a SI actuated.
C. The first part is plausible because EOP-1.1 contains guidance for restoring pressurizer pressure and energizing heaters and because this action would successfully raise pressure to normal if a spray valve was not stuck open.
Incorrect because energizing pressure heaters will not successfully mitigate a full open spray valve.
D. CORRECT. The correct guidance to trip RCP "A" is contained in EOP-1.1.

In order to answer this question correctly, the applicant must determine that CSFST indications warrant a transfer to EOP-14.0 and identify the basis for the indicators used for that transfer.
A. CORRECT; RVLIS narrow range level is less than the 34% and CET indications are less than 725°F. An Orange path on Core Cooling is indicated and a transfer to EOP-14.1 RESPONSE TO DEGRADED CORE COOLING is required. NR RVLIS <34% means level is less than 3.5 ft above the bottom of the core.
B. First part is correct plausible because RVLIS narrow range level is less than 34% and CET indications are less than 725°F. A transfer to EOP-14.1 is required. Second part is plausible because RVLIS wide range indications on the CSFST are based on 50% void fraction.
Incorrect because 34% RVLIS represents 3.5 ft above the bottom of the core.
C. The first part is plausible because RVLIS NR is less than 34% and CETs are high and at the value of 670°F which is the basis for 725°F before instrument errors are applied. NR RVLIS below the limit and CETs above the limit would indicate a transfer to EOP-14.0 is required.
The second part is plausible because RVLIS wide range indications on the CSFST are based on 50% void fraction.
Incorrect because a transfer to EOP-14.0 is not required and NR RVLIS <34% means level is <3.5 ft above the bottom of the core.
D. The first part is plausible because RVLIS NR is less than 34% and CETs are high and at the value of 670°F which is the basis for 725°F before instrument errors are applied. NR RVLIS below the limit and CETs above the limit would indicate a transfer to EOP-14.0 is required. The second part is correct.

In order to answer this question correctly, the applicant must assess plant conditions and alarms and determine that a full train of containment depressurization equipment is not available. and that filling the RBCUs is the correct response in accordance with the supplemental actions of XCP-604, 2-3 and 3-1.
A. The first part is plausible because two (2) RBCUs are running but only one has adequate Service Water flow. This does not satisfy one train of containment depressurization capability as defined in EPP-108. In accordance with EAL criteria, 2 operable RBCUs are required. The second part is correct; with XVB-3107 A open, filling the RBCUS per SOP-117 is required.
Incorrect because a full train of containment depressurization is not available since both RB Spray pumps are off and 1A RBCU is running without Service Water cooling.
B. CORRECT. A full train of containment depressurization is not available since both RB Spray pumps are off and 1A RBCU is running without Service Water cooling and with XVB-3107 A open, filling the RBCUS per SOP-117 is required.
C. The first part is plausible because two (2) RBCUs are running but only one has adequate Service Water flow. This does not satisfy one train of containment depressurization capability as defined in EPP-108. In accordance with EAL criteria, 2 operable RBCUs are required. The second part is plausible because starting SWBP "A" would be the correct action if XVB-3107A were closed.
Incorrect because a full train of containment depressurization is not available since both RB Spray pumps are off and 1A RBCU is running without Service Water cooling and with XVB-3107 A open, filling the RBCUS per SOP-117 is required.
D. The first part is correct; A full train of containment depressurization is not available since both RB Spray pumps are off and 1A RBCU is running without Service Water cooling. The second part is plausible because starting SWBP "A" would be the correct action if XVB-3107A were closed.

In order to answer this question correctly, the applicant must determine that "A" Train Charging is INOPERABLE due to a loss of CCW cooling and that "B" train Charging is INOPERABLE due to inability to rack down "B" Charging pump breaker. Additionally, the applicant must determine that 3.0.3 is in effect and determine the requirements to be in Hot Standby in accordance with Technical Specifications.
A. The first part is correct; Both trains of charging are INOPERABLE. The second part is plausible as it states the time to Mode 4 is time that 3.0.3 went into effect plus 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.->

B. CORRECT. 3.0.3 is in effect as of the 2nd pump INOPERABILITY at 1300, 8/19/13. The unit must be in HOT STANDBY by 1300 + 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> + 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> = 2000, 8//19/13.
C. Plausible because the candidate may not realize that "A" Charging pump is INOPERABLE even though operation without CCW is temporarily allowed by AOP-118.1. If 3.0.3 is not recognized then, then under an assumption that only the "B" train is INOPERABLE as of 1100, 8/19/13, the Unit would have to be in HOT STANDBY by 1700, 8/22/13 (1100, 8/19/13

In order to answer this question correctly, the applicant must determine the programmed Pressurizer level for the RCS temperature, diagnose that channel 460 is in error and that channels 459A and 461 are OPERABLE, and that with the provisions of 3.0.4 not applicable, the unit can be taken to Mode 1.
A. CORRECT. Programmed pressurizer level for 557°F is 25%. Channel 460 has drifted low outside of the 4% tolerance of OAP-106.1, OPERATING ROUNDS but the two other channels remain OPERABLE. This meets the MINIMUM CHANNELS OPERABLE requirement for T.S. 3/4 3-6 for the Pressurizer Water Level - High Functional. The provisions of T.S. 3.0.4 do not apply so the unit can be taken to Mode 1 even with action statement 6 in effect.

B. Plausible because the first part is correct. Programmed pressurizer level for 557°F is 25%.
Channel 460 has drifted low outside of the 4% tolerance of OAP-106.1, OPERATING ROUNDS but the two other channels remain OPERABLE. This meets the MINIMUM CHANNELS OPERABLE requirement for T.S. 3/4 3-6 for the Pressurizer Water Level - High Functional. The second part is plausible because the candidate may not note that 3.0.4 is not applicable on the given reference or know the meaning of that statement. If it is only recalled that Technical Specifications generally do not allow mode changes while in an action statement for equipment required in the higher mode, then this answer is plausible.
Incorrect because the unit can be taken to Mode 1.
C. Plausible because channels 459A and 461 are both at 25%. If the candidate thinks that these two channels are in error and INOPERABLE, then it may be assumed that the MINIMUM CHANNEL OPERABLE requirements are not met. The second part is plausible because the MODE OF APPLICABILITY for the Pressurizer Water Level- High Function al Unit is Mode 1. In error, the candidate may think that the unit must be held in Mode 2 until OPERABILITY is restored.
Incorrect because the High PZR level trip function is OPERABLE and the unit can be taken to Mode 1.
D. Plausible because channels 459A and 461 are both at 25%. If the candidate thinks that these two channels are in error and INOPERABLE, then it may be assumed that the MINIMUM CHANNEL OPERABLE requirements are not met. The second part is plausible because the candidate may not note that 3.0.4 is not applicable on the reference or know the meaning of that statement.

In order to answer this question correctly, the applicant must determine how AOP-117.1, LOSS OF SERVICE WATER should be used in conjunction with the Emergency Operating Procedures to most effectively proceed to COLD SHUTDOWN.
A. CORRECT. With only "B" Service Water pump available, the Active CCW loop must be swapped to "B" train in order to provide CCW for letdown. EOP-4.1A is the only procedure that can be used since Blowdown is not available for EOP-4.1b and Steam Generator level precludes the use of EOP-4.1 C. and H level >preferred procedure for use and this method requires cooled letdown to enable processing of backfilled water through the CVCS demineralizers and for operation of RHR.
B. Plausible because EOP-4.1A is the preferred procedure for use and this distracter provides eventual restoration of CCW.
Incorrect because CCW is required in EOP-4.1A for CVCS letdown, excess letdown and RHR.
C. Plausible because EOP-4.1C is a choice in EOP-4.1 and provides the fastest method for processing a rupture SG and proceeding to COLD SHUTDOWN. This distracter provides the correct method of restoring CCW.
Incorrect because the high SG level precludes the use of steam dumps for depressurizing the ruptured SG.
D. Plausible because EOP-4.1C is a choice in EOP-4.1 and provides the fastest method for processing a rupture SG and proceeding to COLD SHUTDOWN and this distracter provides restoration of CCW.
Incorrect because the high SG level precludes the use of steam dumps for depressurizing the ruptured SG and CCW trains would be swapped while proceeding with the EOP recovery procedure.

In order to answer this question correctly, the applicant must determine that diesel is INOPERABLE based on the given information and that a check of TD EFW pump is required.
A. The first part is plausible because the diesel is currently attached to the bus and the candidate may assume that the diesel function is therefore satisfied. This is incorrect since the breaker cannot open due to a trip and it is required to open if operating in parallel and a SI is actuated. The second part is correct; A diesel INOPERABLITY while in Mode 1 requires a check to ensure that the Turbine-driven EFW pump is OPERABLE.
Incorrect because "B" EDG is INOPERABLE due to the loss of 1HB DC power.
B. The first part is plausible because the diesel is currently attached to the bus and the candidate may assume that the diesel function is therefore satisfied. This is incorrect since the breaker cannot open due to a trip and it is required to open if operating in parallel and a SI is actuated. The second part is plausible if the candidate assesses that the loss of breaker control power for bus 1DB also makes the offsite circuit to 1DB INOPERABLE and the 1DA is INOPERABLE due the loss of the ALT FEED breaker. In this case, the candidate may assume in error that 3.0.3 is warranted.

Incorrect because "B" EDG is INOPERABLE due to the loss of 1HB DC power and 3.0.3 in not in effect.
C. CORRECT; "B" EDG is INOPERABLE due to loss of control power to XSW1DB 10, EMERG DIESEL GEN B XEG0001B-DG. This breaker is required to open if "B" EDG is operating in parallel and a SI actuates. For an inoperability of a diesel, verification of the TD EFW pump operability is required per T.S 3.8.1.1 action B.3.
D. The first part is correct; "B" EDG is INOPERABLE due to loss of control power to XSW1DB 10, EMERG DIESEL GEN B XEG0001B-DG. This breaker is required to open if "B" EDG is operating in parallel and a SI actuates. The second part is plausible because the candidate may assess that the loss of breaker control power for bus 1DB and the loss of the ALT FEED breaker result in a loss of OPERABILITY on 2 ESF buses and one diesel which requires entry into 3.0.3. Preparation to lower modes is required within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> by 3.0.3.

In order to answer this question correctly, the applicant must choose the answer that correctly describes the basis for returning back to Step 1 of EOP-4.0 upon indication of additional secondary radiation and why SBLOCA RCP trip criteria do not apply for the conditions given..
A. First part is plausible because there is a transition to EOP-4.2 that occurs in step 3 if isolation cannot be completed between an intact and ruptured steam generator. The RM-A9 indication does not provide distinction between 1 or 2 more ruptured generators and if all three were ruptured this could conceivably require a transfer. The second part is plausible because the step to trip RCPs will be read a second time and the basis for that step is to provide trips for "multiple failure event scenarios". This would be applicable for conditions in which the primary event is a Small break LOCA that requires the RCP trip and there is accompanying secondary radiation that has caused operators to transfer to E-3(EOP-4.0).
Incorrect because evaluation of transition to EOP-4.2 is not the correct reason to return to Step 1 and RCP trip criteria ceased to apply after beginning the previous cooldown.
B. First part is plausible because there is a transition to EOP-4.2 that occurs in step 3 if isolation cannot be completed between an intact and ruptured steam generator. The RM-A9 indication does not provide distinction between 1 or 2 more ruptured generators and if all three were ruptured this could conceivably require a transfer. The second part is correct; The SBLOCA RCP trip criteria ceased to apply after beginning the Operator controlled cooldown.
Incorrect because evaluation of transition to EOP-4.2 is not the correct reason to return to Step 1.
C. The first part is correct; The basis for returning to Step 1 upon receipt of additional secondary radiation is to perform the isolation of the additional ruptured generator. The second half is plausible because the step to trip RCPs will be read a second time and the basis for that step is to provide trips for "multiple failure event scenarios". This would be applicable for conditions in which the primary event is a Small break LOCA that requires the RCP trip and there is accompanying secondary radiation that has caused operators to transfer to E-3(EOP-4.0).
Incorrect because RCP trip criteria ceased to apply after beginning the previous cooldown.
D. CORRECT; The basis for returning to Step 1 upon receipt of additional secondary radiation is to perform the isolation of the additional ruptured generator. The SBLOCA RCP trip criteria ceased to apply after beginning the Operator controlled cooldown.

A. The first part is plausible because a fire lasted 20 minutes in the Intermediate Building and therefore meets conditions for a UE declaration. This is not the highest and therefore is not correct. The second part is correct; Per drawing D-101-017 G-6, the door to the Turbine
-Driven EFW Pump Room is IB-102; Per FPP-025, Enclosure 6.3, page 2, door IB-102 is a Fire Rated Assembly (FRA).
Incorrect because a UE is not the highest EAL declaration.
B. The first part is plausible because a fire lasted 20 minutes in the Intermediate Building and therefore meets conditions for a UE declaration. This is not the highest and therefore is not correct. The second part is plausible because CB-102 may be cross-referenced in error and it is a Fire Rated Assembly and a Steam Propagation Barrier (SPB) as indicated on page 1 of FPP-025, Enclosure 6.3.
Incorrect because a UE is not the highest EAL declaration and door IB-102 is not a SPB.

Rev. 0 submitted by RJ Ops Review: Nick O'Kimosh Approved: 6/17/13 Rick Garner DISTRACTOR ANALYSIS:
In order to answer this question correctly, the applicant must recall the limit and its basis that preclude starting an RCP while the RCS is less than 300°F.
A. The first part is correct; When the RCS is less than 300°F and with Pressurizer level greater than 92%, a RCP cannot be started because "C" TCOLD is more than 50°F below "C" Steam Generator temperature. The second part is plausible because the specification ensures that the reliefs provide sufficient capacity, but not that reliefs do not lift.
Incorrect because the basis is for the potential for brittle facture due to overpressurization.
B. CORRECT. When the RCS is less than 300°F and with Pressurizer level greater than 92%,
a RCP cannot be started when the lowest TCOLD temperature is not within 50°F of the highest Steam Generator temperature and the basis for that requirement is to prevent brittle fracture due to overpressurization.
C. The first part is plausible because the highest TCOLD is within 50°F of "C" Steam Generator temperature. The second part is correct; the basis for the requirement is to prevent brittle fracture due to overpressurization.
Incorrect because all TCOLDS must be within 50°F of all Steam Generator temperatures and the basis is the potential for brittle facture rather than to ensure that reliefs do not lift.
D. The first part is plausible because "C" TCOLD is within 50°F of "C" Steam Generator temperature. The second part is plausible because a cooldown of RCS portion of the steam generator will occur and the administrative cooldown limit is 50°/hr per GOP-6.
Incorrect because all TCOLDS must be within 50°F of all Steam Generator temperatures..
K/A: G2.1.32: Ability to explain and apply system limits and precautions.

SRO Justification: SRO Only because the question tests knowledge the Technical Specification basis that precludes starting RCPs when the RCS is below 300° if conditions are present that would create an excess overpressurization.
401-9 comment from submittal of 10 question sample:
Cred Dist: The second part of A&C are not plausible because the temperatures are only 47, 51
& 51 oF apart to begin with so exceeding a cooldown rate limit would be impossible unless you have something going on to keep one of the temperatures constant.
The analysis states the lowest TCOLD temperature is not within 50 oF of the highest Steam Generator. The actual limit seems to state that it would apply to individual loops. Correct me if Im wrong.
The second half of distracters A and C were changed to present a plausible reason for preventing overpressurization. With regard to the second comment, the actual specification is as follows:
Reactor Coolant pump shall not be started with one or more of the Reactor Coolant System cold leg temperatures less than or equal to 300°F unless 1) the pressurizer water volume is. less than 1288 cubic- feet and/or 2) the secondary water -temperature of each steam generator is less than 50°F above each of the Reactor Coolant System cold leg temperatures.
The justification is correct as stated in that all tcolds must be within all SG temperatures.

Rev. 0 submitted by RJ Ops Review: Nick O'Kimosh Approved: 6/17/13 Rick Garner DISTRACTOR ANALYSIS:
In order to answer this question correctly, the applicant apply knowledge of work-hour requirements determine when a limit is reached and in accordance with SAP-152, FATIGUE MANAGEMENT AND WORK HOUR LIMITS and assess conditions to determine the proper basis for a waiver. This also requires knowledge that the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> allowance of T.S.

In order to answer this question correctly, the applicant must recall the definition of a Hostile Action in accordance with EPP-108,EMERGENCY ACTION LEVEL TECHNICAL BASIS DOCUMENT.
A. Plausible because the candidate may assume that a HOSTILE ACTION may have occurred under the classic definition of "hostile" as follows (from Merriam Webster.com:)
1 a : of or relating to an enemy b: marked by malevolence: having or showing unfriendly feelings c: openly opposed or resisting Incorrect because in accordance with EPP-108, a definition of HOSTILE ACTION is an act toward a nuclear power plant or its personnel that includes the use of violent force to destroy equipment, take hostages, and/or intimidates the licensee to achieve an end. This includes attack by air, land or water using guns, explosives, projectiles, vehicles or other devices used to deliver destructive force. Other acts that satisfy the overall intent may be included. Hostile Action should not be construed to include acts of civil disobedience or felonious acts that are not part of a concerted attack on the plant. Non-terrorism-based EALs should be used to address such activities, (e.g., violent acts between individuals in the owner controlled area.
B. Plausible because the candidate may assume that because a lethal act occurred within the Protected Area that this constitutes a Hostile Action.
Incorrect because a Hostile Action should not be construed to include acts of civil disobedience or felonious acts that are not part of a concerted attack on the plant.
C. CORRECT. Armed intruders that act in concert with acts of violence upon personnel constitute a Hostile Action. This is less severe than distracter D in which explosives are actually detonated in the Protected area resulting in injury to employees and destruction of vital safety equipment.
D. Plausible because armed intruders that act in concert with acts of violence upon personnel constitute a Hostile Action.
Incorrect because this is not the least severe since this results in injury to employees and damage to vital safety equipment inside the Protected Area.

In order to answer this question correctly, the applicant must use knowledge of EPP-012, ONSITE PERSONNEL ACCOUNTABILITY AND EVACUATION and determine the lasted time by which evacuation and accountability has been completed and determine the requirement for the location where personnel will be directed.
A. The first part is plausible because the Evacuation and accountability must be completed within 30 minutes during a SAE. If the applicant assumes in error that accountability is Thursday, June 27, 2013 8:12:52 AM 75
required for Alert then 1500 + 30 min = 1530. The second part is plausible because employees may be directed to their residences if they are not or could not be contaminated.
Incorrect because the correct time for completion of Accountability is 1600 and non-essential personnel will be directed to a holding area when there is potential for personnel or vehicle contamination. Since there is a small breach in the reactor building, there is the potential for that to have occurred at the site.
B. The first part is correct; The Evacuation and accountability must be completed within 30 minutes after declaration of a SAE. 1530 + 30 min = 1600. The second part is plausible because employees may be directed to their residences if they are not or could not be contaminated.
Incorrect because non-essential personnel will be directed to a holding area when there is potential for personnel or vehicle contamination. Since there is a small breach in the reactor building, there is the potential for that to have occurred at the site.
C. The first part is plausible because the Evacuation and accountability must be completed within 30 minutes during a SAE. If the applicant assumes in error that accountability is required for Alert then 1500 + 30 min = 1530. The second part is correct; All non-essential personnel will be directed to a holding area when there is potential for personnel or vehicle contamination. Since there is a small breach in the reactor building, there is the potential for that to have occurred at the site.
Incorrect because evacuation and accountability must be completed by 1530.
D. CORRECT. Evacuation and accountability must be completed within 30 minutes during a SAE (1530 + 30 min = 1600) and non-essential personnel will be directed to a holding area when there is potential for personnel or vehicle contamination. Since there is a small breach in the reactor building, there is the potential for that to have occurred at the site.
