(1) Trip the Reactor and enter E-0, Reactor Trip or Safety Injection (2) Alert Answer: A Explanation: The leak rate calculation can be determined by reading the Charging header Flow (130 gpm), Letdown Flow (75 gpm), and the assumed normal RCP seal leakoff is 3 gpm per RCP. VCT and PZR level indication are provided to indicate that a Reactor Trip are not required due to low level in either. With the following calculation the leak rate is determined:
-BB-00003, what action will be directed by the CRS
Charging Flow - Letdown Flow - RCP Seal Leak off = Leakage Rate 130-75-12=43 gpm A. Correct - Based on OTO-BB-00003 Step 9 continuous action, the leak rate is LESS than 50 gpm, therefore a reactor trip is NOT required and the crew will perform Step 25 to commence a reactor shutdown in accordance with OTO-MA-00008, due to leakage in excess of T/S 3.4.13 RCS Operational Leakage exceeding the Unidentified Leakage Limit of 1 gpm. The leak rate is greater than 10 gpm Unidentified leakage and is therefore above the threshold for declaring an Unusual Even per SU6.1.
?  And  (2) What is the HIGHEST EAL declaration that will be made?
B. Incorrect - This is the correct EAL determination, however the leak rate is not greater than 50 gpm, PZR level is stable and VCT level is stable. A low PZR level, VCT level, or High leak rate reactor trip is NOT required. The correct action is to shutdown the reactor in a controlled manner.

-0, Reactor Trip or Safety Injection (2) Alert  Answer: A  Explanation:
The leak rate calculation can be determined by reading the Charging header Flow (130 gpm), Letdown Flow (75 gpm), and the assumed normal RCP seal leakoff is 3 gpm per RCP. VCT and PZR level indication are provided to indicate that a Reactor Trip are not required due to low level in either.
With the following calculation the leak rate is determined:
Charging Flow
- Letdown Flow
- RCP Seal Leak off = Leakage Rate 130-75-12=43 gpm  A. Correct - Based on OTO
-BB-00003 Step 9 continuous action, the leak rate is LESS than 50 gpm, therefore a reactor trip is NOT required and the crew will perform Step 25 to commence a reactor shutdown in accordance with OTO
-MA-00008, due to leakage in excess of T/S 3.4.13 RCS Operational Leakage exceeding the Unidentified Leakage Limit of 1 gpm. The leak rate is greater than 10 gpm Unidentified leakage and is therefore above the threshold for declaring an Unusual Even per SU6.1.
B. Incorrect
- This is the correct EAL determination, however the leak rate is not greater than 50 gpm, PZR level is stable and VCT level is stable. A low PZR level, VCT level, or High leak rate reactor trip is NOT required. The correct action is to shutdown the reactor in a controlled manner.
C. Incorrect
- Based on OTO
-BB-00003 Step 9 continuous action, the leak rate is LESS than 50 gpm, therefore a reactor trip is NOT required and the crew will perform Step 25 to commence a reactor shutdown in accordance with OTO
-MA-00008, due to leakage in excess of T/S 3.4.13 RCS Operational Leakage exceeding the Unidentified Leakage Limit of 1 gpm. This EAL determination is incorrect due to leak rate not exceeding 120 gpm. It is plausible because this is a compromise of the RCS barrier as indicated by the RCS leak D. Incorrect - The leak rate is not greater than 50 gpm, PZR level is stable and VCT level is stable. A low PZR level, VCT level, or High leak rate reactor trip is NOT required.

And (2) What action is required to mitigate this conditi on?
NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Answer: B Explanation:
A. (1) RCP Seal Injection Header Rupture (2) Perform OT N-B G-0000 1 , Addendum 4, Operation of CVCS Letdown B. (1) RCP Seal Injection Header Rupture (2) Perform OTO
The indications represent a RCP Seal Injection Header Leak is present - High NCP charging flow, low seal injection flow, and VCT level lowering with 75 gpm letdown in service. When Air is lost to BG FCV-124, the valve will Fail OPEN which would cause a high NCP flow, making this a plausible distractor, but would not cause RCP seal injection flow low annunciator. The values of the leak were chosen such that the leak rate, if calculated, would be less than 50 gpm. A leak rate of > 50 gpm would require a transition to E-0 making none of the choices correct. Also PZR level NOT stable or rising would cause a transition to E-0 because of step #2 of OTO-BB-00003, which is a continuous action step. Therefore, the question stem indicates that PZR level is stable.
-BB-00003, Attachment C, Auxiliary Building Leak Search C. (1) Loss of air to BG FCV
For the procedure selection, with containment conditions normal (no information is provided that there are abnormal containment conditions, the RNO column of step 8 of OTO-BB-00003 would NOT be performed and would continue on in the procedure. The RNO column of step 13 applies (based on DRW level rising) and the CRS will direct Attachment C, Auxiliary Building Leak Search.
-124, NCP Flow Control Valve (2) Perform OTO
OTN-BG-00001, Addendum 4, Operation of CVCS Letdown is the normal operation procedure for CVCS for such activities as placing and removing letdown from service. This Addendum is not directed from OTO-BB-00003 but is directed from OTO-BG-00001.
-BG-00001, Attachment H, Establishing Excess Letdown D. (1) Loss of air to BG FCV
If the candidate misdiagnoses the plant conditions and believes that a PZR level control malfunction is occurring (either due to a failed instrument or a FCV failure), then entry into OTO-BG-00001 is plausible and direction to isolate letdown and then establish excess letdown in step 7 RNO is plausible. This diagnosis is plausible as PZR level low out of band and a higher charging flow are given in the stem. This is wrong as none of this would explain why there is a seal injection flow low annunciator LIT. If the candidate believes that a loss of air to BG FCV 124 causing the valve to fail closed, then a loss of charging would have occurred and letdown would have isolated on low PZR level and after manual control of BG FCV 124 is taken in step 3, step 7 RNO would be applicable and hence why this choice is plausible.
-124, NCP Flow Control Valve (2) Perform OTO
OTO-KA-00001, Loss of Instrument Air, Attachment H will locate and isolate air to specific valves outside of containment. This would be the correct subsequent path, following OTO-BG-00001, to restore pressurizer level due to the loss of instrument air to BG FCV 124. However, as explained above, this is not the correct diagnosis of the event in progress but is plausible for a loss of air to the valve.
-KA-00001, Attachment H , Air Operated Valves Outside Containment
 
NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Answer: B Explanation:
The indications represent a RCP Seal Injection Header Leak is present  
- High NCP charging flow, low seal injection flow, and VCT level lowering with 75 gpm letdown in service. When Air is lost to BG FCV
-124, the valve will Fail OPEN which would cause a high NCP flow, making this a plausible distractor, but would not cause RCP seal injection flow low annunciator. The values of the leak were chosen such that the leak rate, if calculated, woul d be less than 50 gpm. A leak rate of > 50 gpm would require a transition to E
-0 making no ne of the choices correct. Also PZR level NOT stable or rising would cause a transition to E
-0 because of step #2 of OTO
-BB-00003, which is a continuous action step. Therefore
, the question stem indicates that PZR level is stable.
For the procedure selection, with containment conditions normal (no information is provided that there are abnormal containment conditions, the RNO column of step 8 of OTO
-BB-00003 would NOT be performed and would continue on in the procedure. The RNO column of step 13 applies (based on DRW level rising) and the CRS will direct Attachment C, Auxiliary Building Leak Search.
OTN-BG-00001, Addendum 4, Operation of CVCS Letdown is the normal operation procedure for CVCS for such activities as placing and removing letdown from service. This Addendum is not directed from OTO
-BB-00003 but is directed from OTO
-BG-00001. If the candidate misdiagnos es the plant conditions and believes that a PZR level control malfunction is occurring (either due to a failed instrument or a FCV failure), then entry into OTO
-BG-00001 is plausible and direction to isolate letdown and then establish excess letdown in step 7 RNO is plausible. This diagnosis is plausible as PZR level low out of band and a higher charging flow are given in the stem.
Th is is wrong as none of this would explain why there is a seal injection flow low annunciator LIT.
I f the candidate believes that a loss of air to BG FCV 124 causing the valve to fail close d , then a loss of charging would have occurred and letdown would have isolated on low PZR level and after manual control of BG FCV 124 is taken in step 3, step 7 RNO would be applicable and hence why this choice is plausible
.
OTO-KA-00001, Loss of Instrument Air, Attachment H will locate and isolate air to specific valves outside of containment. This would be the correct subsequent path, following OTO
-BG-00001, to restore pressurizer level due to the loss of instrument air to BG FCV 124. However, as explained above, this is not the correct diagnosis of the event in progress but is plausible for a loss of air to the valve.

And (2) What is the LATEST notification time to the state and local agencies associated with this event
NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Given the current plant status with a loss of offsite power, NB01 will be the only bus with power (supplied from NE01). This meets the ALERT criteria for SA1 AC power capability buses reduced to a single power source for greater than or equal to 15 minutes such that any additional single failure would result in a station blackout. Therefore an ALERT declaration of SA1.1 is correct. The unusual event is plausible if the candidate does not correctly process the loss of NB02 due to the DG not being available and determines an EAL SU1.1, an Unusual Event, is the only emergency classification threshold reached due to the loss of off-site power.
?
Per APA-ZZ-00520, Attachment 1, Notification of state and local agencies is a 15 minute report upon the declaration of any emergency classification. Since the SRO has 15 minutes to declare the event, the latest the EAL declaration can occur is 0815. Then the SRO has an additional 15 minutes to notify state and local agencies which makes 0830 correct. The distractor of 0915 is plausible if the candidate incorrectly recalls that state and local agencies are notified within one hour (which is the notification time requirement to the NRC).

There are 24 hours left on the original time clock for condition B, therefore 24 +
6 = 30 hours. The candidate could also arrive at the 30 hour distractor by only applying 3.8.1C which has a 24 hour completion time. This time added with the 6 hours of 3.8.1 G would also yield a 30 hour time limit.

), the re is a 12 hour completion time before 3.8.1 G is applied. This would give the candidate a calculated time of 18 hours. (12 hours of D + 6 hours of G).
If the candidate applies 3.8.1 D (1 DG and 1 offsite circuit inop) as limiting (incorrectly), there is a 12 hour completion time before 3.8.1 G is applied. This would give the candidate a calculated time of 18 hours. (12 hours of D + 6 hours of G).
If the candidate applies the note in 3.8.1 condition D to enter LCO 3.8.9 condition A to restore within 8 hours and then proceeds to applies 3.8.9 Condition D to be in Mode 3 within 6 hours, the calculated time would be 14 hours.

Per technical specification bases 3.3.8 background section "High gaseous radiation, monitored by two channels, provides a FBVIS. Both EES trains are initiated by high radiation detected by either channel.
Per technical specification bases 3.3.8 background section High gaseous radiation, monitored by two channels, provides a FBVIS. Both EES trains are initiated by high radiation detected by either channel. Each channel contains a gaseous monitor. High radiation detected by either monitor initiates fuel building isolation, starts the EES, and initiates a CRVIS. This information is also repeated in FSAR section 15.7.4.5 Radiological Consequences. Therefore BOTH trains actuated is correct.

Both OSP-SF-00003 and OTG-ZZ-00007 have step s prior to movement of Irradiated fuel assemblies in the fuel building to "ENSURE the Fuel Storage Pool boron concentration is greater than or equal to 2165 ppm." but this is not the reason why fuel moves are delayed until 72 hours after the reactor is subcritical. Plausible as this is a precaution, note, and step in the procedure s and it does take time to raise and ensure boron concentration is >2165 ppm.

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Explanation:
The entry conditions for OTO
The entry conditions for OTO-BB-00005, High RCS activity, have been met for 2 reasons - Dose Equivalent I-131 and SJ-RE-01 in alarm. The first action of this procedure, i.e step 1, is to maximize flow through the CVCS Letdown Mixed Bed Demineralizer. The distractor of isolate Letdown is plausible since the candidate may falsely believe the action is to isolate Letdown to reduce the spread of contamination through the CVCS system. This is wrong as it is the exact opposite of what OTO-BB-00005 requires the operator to do.
-BB-00005, High RCS activity, have been met for 2 reasons  
Based on the plant conditions, an Unusual Event condition of Fuel clad degradation exists (dose Equivalent I-131 greater than 75 µCi/gm for greater than 48 hours). This would result in a SU5.1 declaration if it was the only threshold met. But an unusual event is not the highest threshold met as the condition for FA1.1 have been met due to a loss of the fuel clad barrier due to Radiation due to the CVCS letdown radiation monitor, SJ-RE-01, reading more than 25
- Dose Equivalent I
µCi/ml. Therefore the highest EAL is an Alert due to FA1.1, any Loss or any potential loss of either Fuel Clad or RCS.

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator (2) Transition to ES-0.4, Natural Circulation Cooldown With Steam Void In Vessel (Without RVLIS)
to verify that the alarms are consistent with the plant conditions.
Answer: A Explanation:
Question #
A RVLIS is powered from NN01 so a loss of NN01 means that A RVLIS is not available.
1 0 Given the following plant conditions:
Therefore the A train of RVLIS is inoperable but the B Train is operable.
A Reactor trip occurred due to a loss of offsite power
And per the NOTE prior to step 13 in ES-0.2 that states:
. Shortly after the trip, the BOP reports the following annunciators are LIT: o 25A, NN01 INST BUS UV o 57E, RVLIS PWR Failure The operating crew is performing ES-0.2, Natural Circulation Cooldown. RCS pressure is 1920 psig. The RCS cooldown and depressurization MUST be performed due to secondary systems water inventory concerns.
If at any time it is determined that a natural circulation cooldown and depressurization must be performed at a rate that may form a steam void in the vessel, one of the following procedures should be used:
It is suspected that a steam void has formed in the RX Vessel.  (1) Which of the following annunciators can be used to verify that a steam void has formed in the RX Vessel?
 
And (2) The CRS will direct which of the following procedures

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator (2) Transition to ES
-0.4, Natural Circulation Cooldown With Steam Void In Vessel (Without RVLIS
Answer: A Explanation:
'A' RVLIS is powered from NN01 so a loss of NN01 means that A RVLIS is not available. Therefore the 'A' train of RVLIS is inoperable but the B Train is operable.
And per the NOTE prior to step 13 in ES
-0.2 that states:
"If at any time it is determined that a natural circulation cooldown and depressurization must be performed at a rate that may form a steam void in the vessel, one of the following procedures should be used:
ES0.3, Natural Circulation Cooldown With Steam Void In Vessel (With RVLIS) or ES0.4, Natural Circulation Cooldown With Steam Void In Vessel (Without RVLIS)
ES0.3, Natural Circulation Cooldown With Steam Void In Vessel (With RVLIS) or ES0.4, Natural Circulation Cooldown With Steam Void In Vessel (Without RVLIS)
Therefore, ES
Therefore, ES-0.3 is correct based on plant conditions and the fact that one train of RVLIS is operable.
-0.3 is correct based on plant conditions and the fact that one train of RVLIS is operable.
If A Steam void is suspected of forming in the vessel, this void will force water into the pressurizer and annunciate 32A, PZR level high. Pressurizer pressure would be going up not down as the PZR bubble would be squeezed by the incoming surge. This question is basically modeling the TMI accident with the exception of a failed open PZR PORV. With a LOCA in progress, it is plausible that a low PZR Pressure Alarm will be received. While there is no LOCA in this question, 33C is plausible if the student applies the TMI accident concept from memory without understanding the reason. Furthermore, step 13 of ES-0.2, RNO for part C directs using a PZR PORV as letdown would not be in service. Opening the PZR PORV would give the PZR Low alarm as pressure is relieved to the PRT. However, as explained above, the Note prior to step 13 would direct the operator to either ES-0.3 or ES-0.4 and the crew would not be performing step

The Callaway Plant is in MODE 4. RCS pressure is being controlled at 500 psig. All wide range Cold Leg temperatures are 270°F.
Cold Overpressure Protection is in ARMED.

A. (1) Only the B Train PORV , BB PCV 456A , will open. (2) Restore SI Pumps to be capable of injection per O SP-EM-00002, Section 7.1 Restoring SI System.
NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator D. (1) Both PORVs, BB PCV 455A and BB PCV 456A, will open.
B. (1) Only the B Train PORV , BB PCV 456A , will open.

(2) Restore SI Accumulators per OTN-EP-00001, Addendum 6, SI Accumulator Isolation and Restoration. C. (1) Both PORVs, BB PCV 455A and BB PCV 456A , will open.
Answer: A Explanation: The is a common misconception that for this situation (with COMS Armed) that both PZR PORVs will open due to a failure of the Loop 1 WR T cold . The inputs into the logic are as follows:
(2) Restore SI Pumps to be capable of injection per OSP
T hot           T cold           WR Pressure         PORV A Train           1,2             3,4             BB PT 405           BB PCV 455A B Train           3,4             1,2             BB PT 406           BB PCV 456A Therefore, when Loop 1 T cold Fails Low ONLY BB PCV 456A will be affected.
-EM-00002, Section 7.1 Restoring SI System.
Per Annunciator 35B PORV open, step 3.3 - IF the PORVs should NOT be OPEN:
 
3.3.1. IF excessive RCS leakage is indicated, Go To OTO-BB-00003, Reactor Coolant System Excessive Leakage. The report that PZR level is lowering means that the crew will NOT stay in OTO-BB-00003 and transition to OTO-BB-000010, Shutdown LOCA.
NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator D. (1) Both PORV s, BB PCV 455A and BB PCV 456A , will open.
This is given in the stem as the entry conditions for OTO-BB-00010, are RO knowledge and not being tested here. OTO-BB-00010 step 10 directs that SI and CCP system be realigned as they have been placed in a lineup for COMS. OSP-EM-00002 section 7.1 is correct as it would restore SI system for injection. OTN-EP-00001 is plausible as it would also met the same strategy of recovering an ECCS system for injection into the vessel but is NOT directed from OTO-BB-00010 and therefore wrong. SI accumulators are pressurized to ~650psig and with RCS pressure at 500 psig they could inject.
(2) Restore SI Accumulators per OTN-EP-00001, Addendum 6, SI Accumulator Isolation and Restoration.
A. Correct B. Incorrect - wrong procedure C. Incorrect - wrong # of PORV opening D. Incorrect - Both reasons are wrong Technical Reference(s):.
Answer: A Explanation:
: 1. OTA-RK-00018, Addendum 35B, PORV Open, Rev 0
The is a common misconception that for this situation (with COMS Armed) that both PZR PORVs will open due to a failure of the Loop 1 WR T cold. The inputs into the logic are as follows:
T hot T cold WR Pressure PORV A Train 1,2 3,4 BB PT 405 BB PCV 455A
 
B Train 3,4 1,2 BB PT 406 BB PCV 456A Therefore, when Loop 1 T cold Fails Low ONLY BB PCV 456A will be affected.
 
Per Annunciator 35B PORV open, step 3.3  
- 'IF the PORVs should NOT be OPEN:
3.3.1. IF excessive RCS leakage is indicated, Go To OTO
-BB-00003, Reactor Coolant System Excessive Leakage."
The report that PZR level is lowering means that the crew will NOT stay in OTO
-BB-00003 and transition to OTO
-BB-000010, Shutdown LOCA. This is given in the stem as the entry conditions for OTO
-BB-00010, are RO knowledge and not being tested here. OTO
-BB-00010 step 10 directs that SI and CCP system be realigned as they have been placed in a lineup for COMS. OSP
-EM-00002 section 7.1 is correct as it would restore SI system for injection. OTN-EP-00001 is plausible as it would also met the same strategy o f recovering an ECCS system for injection in to the vessel but is NOT directed from OTO

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Answer: B Explanation:
With Shutdown Bank Control rod P
With Shutdown Bank Control rod P-4 fully inserted, a local Xenon transient began 12 hours ago.
-4 fully inserted, a local Xenon transient began 12 hours ago. The Production of Iodine (XE precursor)
The Production of Iodine (XE precursor), which is dependent of the number of fissions locally, lowered but so did the burnout of Xenon due to the lower neutron flux. This results in local Xenon concentration spiking over the next 6-10 hours, reaching a peak ~10 hours after the dropped rod.
, which is dependent of the number of fissions locally
After this point, local Xenon concentration will lower as less Xenon is produced (less Iodine) resulting in less of a local poison concentration. Less poison encourages neutron flux and which the rising flux there is more neutron leakage resulting in more neutrons reaching NI 41. The results would be a NI 41 reading rising as the xenon concentration lowers.
, lowered but so did the burnout of Xenon due to the lower neutron flux. This results in local Xenon concentration spiking over the next 6
Due to the malfunction, the crew will be implementing OTO-SF-00001. Specifically, the crew will be at step A11 waiting for I&C to find and fix the cause of the malfunction. Upon the report that the problem has been found and corrected, the CRS will direct performance of OTO-SF-00001 Attachment B per step A12.
-10 hours, reaching a peak ~10 hours after the dropped rod. After this point, local Xenon concentration will lower as less Xenon is produced (less Iodine) resulting in less of a local poison concentration. Less poison encourages neutron flux and which the rising flux there is more neutron leakage resulting in more neutrons reaching NI 41. The results would be a NI 41 reading rising as the xenon concentration lowers.
ESP-ZZ-00004 is plausible as it is performed concurrently with ESP-ZZ-00006, Incore/Excore Calibration. This is plausible as a quadrant power tilt is occurring from the dropped rod and xenon transient. However, as the Xenon transient is in progress and the prerequisites of ESP-ZZ-00004 require xenon is within 5% of equilibrium, this is not the correct application of this procedure. Correcting the initial problem (dropped rod) is the correct choice which will then correct the QPTR concern.

Answer: C Explanation:
Answer: C Explanation:
Per ODP-ZZ-00001 Addendum 10, step 2.1.5 states that "Designate a Reactivit y Management SRO (RMSRO) to direct Reactor Operations whenever reactor power is changed by more than 5 %
Per ODP-ZZ-00001 Addendum 10, step 2.1.5 states that Designate a Reactivity Management SRO (RMSRO) to direct Reactor Operations whenever reactor power is changed by more than 5 % in one direction. This includes:
in one direction. This includes:
* Reactor startup
* Reactor startup
* Lowering power in MODES 1 and 2
* Lowering power in MODES 1 and 2
* Raising power in MODES 1 and 2
* Raising power in MODES 1 and 2
* Withdrawal of Shutdown Banks
* Withdrawal of Shutdown Banks
* Diluting for Physics Testing post refuel."
* Diluting for Physics Testing post refuel.
Therefore, RCS Dilution for Low Power Physics Testing post refuel is correct. Lowering power from 100% to 97% does not meet the power changed by more than 5% criteria and is therefore incorrect.
Therefore, RCS Dilution for Low Power Physics Testing post refuel is correct. Lowering power from 100% to 97% does not meet the power changed by more than 5% criteria and is therefore incorrect.
ODP-ZZ-00001, step 3.6.1 states  
ODP-ZZ-00001, step 3.6.1 states The CRS normally performs the responsibilities of the RMSRO during steady state and emergent plant conditions. The CRS may also perform the RMSRO function during reactor startup. Therefore, since this is an emergent power reduction operations management is NOT required to designate an additional SRO to fulfill the RMSRO position.

* The surveillance was performed satisfactorily 80 hours ago.
Question #
What is the LATEST time, from 0800, in which the surveillance requirement must be completed satisfactorily to be within its Specified Frequency.
22 Given the following plant conditions:   At 0800, it was determined that a surveillance requirement which was due at midnight the previous shift was not performed.
A. 10 hours B. 18 hours C. 24 hours D. 72 hours Answer: A Explanation:
The surveillance requirement frequency is once per 72 hours.
This question involves the application of SR 3.0.2 and SR 3.0.3. First it is necessary to calculate the 25% grace period that is specified in SR 3.0.2. 72 hours x 0.25 = 18 hours. Since the surveillance is still within its grace period, the remainder of the grace period will be used to perform the surveillance within its specified frequency. The time remaining on the grace period is 10 hours (18 hours - (80-72 hours)) as 8 hours of the grace period has elapsed by 0800.
The surveillance was performed satisfactorily 80 hours ago.
Therefore, 10 hours is the Latest time in which the SR may be completed sat and the specified frequency be met.
 
A. Correct - see above B. Incorrect - plausible if the candidate calculates the grace period correctly but does not apply the correct starting time of the grace period i.e. assumes the grace period starts at 0800 instead of when the normal 72 hours was up (i.e 8 hours ago).
What is the LATEST time , from 0800 , in which the surveillance requirement must be completed satisfactorily to be within its Specified Frequency.
A. 10 hours B. 18 hours C. 24 hours D. 72 hours   Answer: A Explanation:
 
This question involves the application of SR 3.0.2 and SR
 
====3.0.3. First====
it is necessary to calculate the 25% grace period that is specified in SR 3.0.2. 72 hours x 0.25 = 18 hours. Since the surveillance is still within its grace period, the remainder of the grace period will be used to perform the surveillance within its specified frequency. The time remaining on the grace period is 10 hours (18 hours  
- (80-72 hours)) as 8 hours of the grace period has elapsed by 0800. Therefore, 10 hours is the Latest time in which the SR may be completed sat and the specified frequency be met.
A. Correct - see above B. Incorrect  
- plausible if the candidate calculates the grace period correctly but does not apply the correct starting time of the grace period i.e. assume s the grace period starts at 0800 instead of when the normal 72 hours was up (i.e 8 hours ago).
NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator C. Incorrect
- plausible if the candidate does not understand that SR 3.0.3 is used for situations when the specified frequency in NOT met. SR 3.0.3 provides 2 time periods
: "from the time of discovery, up to 24 hours or up to the limit of the specified fre q u ency, whichever is greater"  24 hours is plausible is the candidate thinks it is 24 maximum or believes it says "whichever is less".
D. Incorrect
- plausible if the candidate does not understand that SR 3.0.3 is used for situations when the specified frequency in NOT met. SR 3.0.3 provides 2 time periods "from the time of discovery, up to 24 hours or up to the limit of the specified frequency, whichever is greater"  72 hours is plausible if the candidate remembers SR 3.0.3 states the maximum of the specified frequency.

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Examination Outline Cross-reference: Level SRO Rev 0 Tier # 1 009 Small Break LOCA Group # 1 K/A # EA2.13 Importance Rating 3.6 Ability to determine or interpret the following as they apply to a small break LOCA:

Charging pump flow indication.

Question #1 (REFERENCE PROVIDED)

Given the following plant conditions:

  • Reactor power is 100%.
  • An RCS Leak has been identified and the crew is performing OTO-BB-00003, RCS Excessive Leakage.
  • Leak Isolation has NOT been successful.
  • The following STABLE indications are observed by the Reactor Operator:

(1) In accordance with OTO-BB-00003, what action will be directed by the CRS?

And (2) What is the HIGHEST EAL declaration that will be made?

A. (1) Commence Reactor Shutdown per OTO-MA-00008, Rapid Load Reduction (2) Unusual Event B. (1) Trip the Reactor and enter E-0, Reactor Trip or Safety Injection

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator (2) Unusual Event C. (1) Commence Reactor Shutdown per OTO-MA-00008, Rapid Load Reduction (2) Alert D. (1) Trip the Reactor and enter E-0, Reactor Trip or Safety Injection (2) Alert Answer: A Explanation: The leak rate calculation can be determined by reading the Charging header Flow (130 gpm), Letdown Flow (75 gpm), and the assumed normal RCP seal leakoff is 3 gpm per RCP. VCT and PZR level indication are provided to indicate that a Reactor Trip are not required due to low level in either. With the following calculation the leak rate is determined:

Charging Flow - Letdown Flow - RCP Seal Leak off = Leakage Rate 130-75-12=43 gpm A. Correct - Based on OTO-BB-00003 Step 9 continuous action, the leak rate is LESS than 50 gpm, therefore a reactor trip is NOT required and the crew will perform Step 25 to commence a reactor shutdown in accordance with OTO-MA-00008, due to leakage in excess of T/S 3.4.13 RCS Operational Leakage exceeding the Unidentified Leakage Limit of 1 gpm. The leak rate is greater than 10 gpm Unidentified leakage and is therefore above the threshold for declaring an Unusual Even per SU6.1.

B. Incorrect - This is the correct EAL determination, however the leak rate is not greater than 50 gpm, PZR level is stable and VCT level is stable. A low PZR level, VCT level, or High leak rate reactor trip is NOT required. The correct action is to shutdown the reactor in a controlled manner.

C. Incorrect - Based on OTO-BB-00003 Step 9 continuous action, the leak rate is LESS than 50 gpm, therefore a reactor trip is NOT required and the crew will perform Step 25 to commence a reactor shutdown in accordance with OTO-MA-00008, due to leakage in excess of T/S 3.4.13 RCS Operational Leakage exceeding the Unidentified Leakage Limit of 1 gpm. This EAL determination is incorrect due to leak rate not exceeding 120 gpm. It is plausible because this is a compromise of the RCS barrier as indicated by the RCS leak D. Incorrect - The leak rate is not greater than 50 gpm, PZR level is stable and VCT level is stable. A low PZR level, VCT level, or High leak rate reactor trip is NOT required. The correct action is to shutdown the reactor in a controlled manner. This EAL determination is incorrect due to leak rate not exceeding 120 gpm. It is plausible because this is a compromise of the RCS barrier as indicated by the RCS leak Technical Reference(s):

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Examination Outline Cross-reference: Level SRO Rev 0 Tier # 1 000022 Loss of RX Coolant Makeup /2 Group # 1 K/A # G2.4.45 Importance Rating 4.3 Ability to prioritize and interpret the significance of each annunciator or alarm.

Question # 2 Callaway is operating at 100% power when a transient occurs.

The following Annunciators are LIT:

  • 32C PZR LO LEV DEV
  • 38A LTDN REGEN HX TEMP HI
  • 41A SEAL INJ TO RCP FLOW LO
  • 41F NCP FLOW HILO The following indications are observed by the Reactor Operator:
  • Charging header flow is 130 gpm and stable.
  • Pressurizer Level is 48% and stable.
  • VCT level is 44% and slowly lowering.
  • DRW Sump level is rising.

(1) Which of the following describes the event in progress?

And (2) What action is required to mitigate this condition?

A. (1) RCP Seal Injection Header Rupture (2) Perform OTN-BG-00001, Addendum 4, Operation of CVCS Letdown B. (1) RCP Seal Injection Header Rupture (2) Perform OTO-BB-00003, Attachment C, Auxiliary Building Leak Search C. (1) Loss of air to BG FCV-124, NCP Flow Control Valve (2) Perform OTO-BG-00001, Attachment H, Establishing Excess Letdown D. (1) Loss of air to BG FCV-124, NCP Flow Control Valve (2) Perform OTO-KA-00001, Attachment H, Air Operated Valves Outside Containment

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Answer: B Explanation:

The indications represent a RCP Seal Injection Header Leak is present - High NCP charging flow, low seal injection flow, and VCT level lowering with 75 gpm letdown in service. When Air is lost to BG FCV-124, the valve will Fail OPEN which would cause a high NCP flow, making this a plausible distractor, but would not cause RCP seal injection flow low annunciator. The values of the leak were chosen such that the leak rate, if calculated, would be less than 50 gpm. A leak rate of > 50 gpm would require a transition to E-0 making none of the choices correct. Also PZR level NOT stable or rising would cause a transition to E-0 because of step #2 of OTO-BB-00003, which is a continuous action step. Therefore, the question stem indicates that PZR level is stable.

For the procedure selection, with containment conditions normal (no information is provided that there are abnormal containment conditions, the RNO column of step 8 of OTO-BB-00003 would NOT be performed and would continue on in the procedure. The RNO column of step 13 applies (based on DRW level rising) and the CRS will direct Attachment C, Auxiliary Building Leak Search.

OTN-BG-00001, Addendum 4, Operation of CVCS Letdown is the normal operation procedure for CVCS for such activities as placing and removing letdown from service. This Addendum is not directed from OTO-BB-00003 but is directed from OTO-BG-00001.

If the candidate misdiagnoses the plant conditions and believes that a PZR level control malfunction is occurring (either due to a failed instrument or a FCV failure), then entry into OTO-BG-00001 is plausible and direction to isolate letdown and then establish excess letdown in step 7 RNO is plausible. This diagnosis is plausible as PZR level low out of band and a higher charging flow are given in the stem. This is wrong as none of this would explain why there is a seal injection flow low annunciator LIT. If the candidate believes that a loss of air to BG FCV 124 causing the valve to fail closed, then a loss of charging would have occurred and letdown would have isolated on low PZR level and after manual control of BG FCV 124 is taken in step 3, step 7 RNO would be applicable and hence why this choice is plausible.

OTO-KA-00001, Loss of Instrument Air, Attachment H will locate and isolate air to specific valves outside of containment. This would be the correct subsequent path, following OTO-BG-00001, to restore pressurizer level due to the loss of instrument air to BG FCV 124. However, as explained above, this is not the correct diagnosis of the event in progress but is plausible for a loss of air to the valve.

(1) lower (2) ensure that the allowable heat generation rate of the fuel is not exceeded Answer: C Explanation:

With a failed High pressure controlling channel, a signal will be processed to open the PZR spray valves in order to lower pressure. Therefore immediately after the failure, RCS pressure will lower.

The reason for the low pressurizer pressure trip is listed in the Technical Specification Bases of 3.3.1 RTS Instrumentation. Per Technical Specification bases of 3.3.1 function 8a- Pressurizer

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Pressure Low; Low trip Function ensures that protection is provided against violating the DNBR limit due to low Pressure. (Tech Spec bases page B3.3.1-21)

Per Technical Specification bases of 3.3.1 function 7; the distractor of ensure that the allowable heat generation rate of the fuel is not exceeded is the bases of overpower delta T trip function.

Overpower delta T trip is T.S. 3.3.1 function 7. RCS Pressure is not an input into the overpower delta T trip setpoint determination. (Tech Spec bases page B3.3.1-19)

And (2) What is the LATEST notification time to the state and local agencies associated with this event?

A. (1) Unusual Event (2) 0830 B. (1) Alert (2) 0830 C. (1) Unusual Event (2) 0915 D. (1) Alert (2) 0915 Answer: B Explanation:

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Given the current plant status with a loss of offsite power, NB01 will be the only bus with power (supplied from NE01). This meets the ALERT criteria for SA1 AC power capability buses reduced to a single power source for greater than or equal to 15 minutes such that any additional single failure would result in a station blackout. Therefore an ALERT declaration of SA1.1 is correct. The unusual event is plausible if the candidate does not correctly process the loss of NB02 due to the DG not being available and determines an EAL SU1.1, an Unusual Event, is the only emergency classification threshold reached due to the loss of off-site power.

Per APA-ZZ-00520, Attachment 1, Notification of state and local agencies is a 15 minute report upon the declaration of any emergency classification. Since the SRO has 15 minutes to declare the event, the latest the EAL declaration can occur is 0815. Then the SRO has an additional 15 minutes to notify state and local agencies which makes 0830 correct. The distractor of 0915 is plausible if the candidate incorrectly recalls that state and local agencies are notified within one hour (which is the notification time requirement to the NRC).

A. Incorrect - the EAL is wrong B. Correct C. Incorrect - Both are wrong D. Incorrect - the notification time is wrong.

Given the following plant conditions:

  • Reactor power is 100%.
  • The A EDG, NE01, was tagged out for lube oil system maintenance 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> ago.
  • An Electrical Grid Disturbance is in progress.
  • The Transmission Operations Supervisor reports that a Category 8 Alarm is received. The Predicted Contingency Voltage is 325 kV.

In order to remain in compliance with the Technical Specifications, the reactor must be in MODE 3 within _______ hours?

A. 7 B. 14 C. 18 D. 30 Answer: A Explanation:

Per Attachment 3 of OSP-NE-00003, If the Predicted Voltage is outside of the required voltage range, the SM/CRS shall declare the offsite circuits INOPERABLE. Per Attachment 5 of OSP-NE-00003, the Contingency Analysis Computer Calculated Operability Limit is in the 372.6 -

(1) ONLY one train actuated (2) to minimize the potential release from a fuel handling accident D. (1) BOTH trains actuated (2) to minimize the potential release from a fuel handling accident

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Answer: D Explanation:

Per technical specification bases 3.3.8 background section High gaseous radiation, monitored by two channels, provides a FBVIS. Both EES trains are initiated by high radiation detected by either channel. Each channel contains a gaseous monitor. High radiation detected by either monitor initiates fuel building isolation, starts the EES, and initiates a CRVIS. This information is also repeated in FSAR section 15.7.4.5 Radiological Consequences. Therefore BOTH trains actuated is correct.

Per OSP-SF-00003, step 6.5.2, the reactor is required to be subcritical for at least 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> prior to the start of core alterations. This is to ensure that iodine inventory low enough which minimizes the potential offsite dose due to a fuel handling accident.

Both OSP-SF-00003 and OTG-ZZ-00007 have steps prior to movement of Irradiated fuel assemblies in the fuel building to ENSURE the Fuel Storage Pool boron concentration is greater than or equal to 2165 ppm. but this is not the reason why fuel moves are delayed until 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after the reactor is subcritical. Plausible as this is a precaution, note, and step in the procedures and it does take time to raise and ensure boron concentration is >2165 ppm.

Given the following plant conditions:

  • The plant is in Mode 4.
  • SJ RE-01, CVCS Letdown Monitor, is in alarm and indicates 30 µCi/ml and slowly rising.
  • PZR Level is 30% and constant.
  • Charging flow is constant.
  • Chemistry reports that Dose Equivalent I-131 is 75 µCi/gm.

(1) The Control Room Supervisor shall direct the crew to ____________?

And (2) Which of the following describes the HIGHEST Emergency Plan Action Level that applies to this situation?

A. (1) isolate Letdown (2) Unusual Event B. (1) isolate Letdown (2) Alert C. (1) maximize Letdown flow through CVCS Letdown Mixed Bed Demineralizer (2) Unusual Event D. (1) maximize Letdown flow through CVCS Letdown Mixed Bed Demineralizer (2) Alert Answer: D

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Explanation:

The entry conditions for OTO-BB-00005, High RCS activity, have been met for 2 reasons - Dose Equivalent I-131 and SJ-RE-01 in alarm. The first action of this procedure, i.e step 1, is to maximize flow through the CVCS Letdown Mixed Bed Demineralizer. The distractor of isolate Letdown is plausible since the candidate may falsely believe the action is to isolate Letdown to reduce the spread of contamination through the CVCS system. This is wrong as it is the exact opposite of what OTO-BB-00005 requires the operator to do.

Question # 10 Given the following plant conditions:

  • Shortly after the trip, the BOP reports the following annunciators are LIT:

o 25A, NN01 INST BUS UV o 57E, RVLIS PWR Failure

  • The operating crew is performing ES-0.2, Natural Circulation Cooldown.
  • RCS pressure is 1920 psig.
  • The RCS cooldown and depressurization MUST be performed due to secondary systems water inventory concerns.
  • It is suspected that a steam void has formed in the RX Vessel.

(1) Which of the following annunciators can be used to verify that a steam void has formed in the RX Vessel?

And (2) The CRS will direct which of the following procedures?

A. (1) 32A, PZR Level High (2) Transition to ES-0.3, Natural Circulation Cooldown With Steam Void In Vessel (With RVLIS)

B. (1) 32A, PZR Level High (2) Transition to ES-0.4, Natural Circulation Cooldown With Steam Void In Vessel (Without RVLIS)

C. (1) 33C, Pressurizer Pressure Low - Heaters On (2) Transition to ES-0.3, Natural Circulation Cooldown With Steam Void In Vessel (With RVLIS)

D. (1) 33C, Pressurizer Pressure Low - Heaters On

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator (2) Transition to ES-0.4, Natural Circulation Cooldown With Steam Void In Vessel (Without RVLIS)

Answer: A Explanation:

A RVLIS is powered from NN01 so a loss of NN01 means that A RVLIS is not available.

Therefore the A train of RVLIS is inoperable but the B Train is operable.

And per the NOTE prior to step 13 in ES-0.2 that states:

If at any time it is determined that a natural circulation cooldown and depressurization must be performed at a rate that may form a steam void in the vessel, one of the following procedures should be used:

ES0.3, Natural Circulation Cooldown With Steam Void In Vessel (With RVLIS) or ES0.4, Natural Circulation Cooldown With Steam Void In Vessel (Without RVLIS)

Therefore, ES-0.3 is correct based on plant conditions and the fact that one train of RVLIS is operable.

If A Steam void is suspected of forming in the vessel, this void will force water into the pressurizer and annunciate 32A, PZR level high. Pressurizer pressure would be going up not down as the PZR bubble would be squeezed by the incoming surge. This question is basically modeling the TMI accident with the exception of a failed open PZR PORV. With a LOCA in progress, it is plausible that a low PZR Pressure Alarm will be received. While there is no LOCA in this question, 33C is plausible if the student applies the TMI accident concept from memory without understanding the reason. Furthermore, step 13 of ES-0.2, RNO for part C directs using a PZR PORV as letdown would not be in service. Opening the PZR PORV would give the PZR Low alarm as pressure is relieved to the PRT. However, as explained above, the Note prior to step 13 would direct the operator to either ES-0.3 or ES-0.4 and the crew would not be performing step

13. Additionally, the PORV operation leading to a low PZR pressure alarm is plausible as certain steps in ES-0.2 direct use of a PZR PORV which would create a low PZR Pressure.

RCS pressure of 1920 psig indicates that the crew is at step 12 of ES-0.2.

Detector failure Question # 16 Given the following plant conditions:

  • The Callaway Plant is in MODE 4.
  • RCS pressure is being controlled at 500 psig.
  • All wide range Cold Leg temperatures are 270°F.
  • Cold Overpressure Protection is in ARMED.
  • Loop 1 Wide Range Cold Leg temperature sensor, TE413B, fails low.

Subsequently;

  • The Crew has transitioned to OTO-BB-00010, Shutdown LOCA.
  • The Reactor Operator reports that Pressurizer Level is lowering.

(1) Which of the following describes the plant response to this failure?

And (2) The CRS will direct which action to mitigate this event?

A. (1) Only the B Train PORV, BB PCV 456A, will open.

(2) Restore SI Pumps to be capable of injection per OSP-EM-00002, Section 7.1 Restoring SI System.

B. (1) Only the B Train PORV, BB PCV 456A, will open.

(2) Restore SI Accumulators per OTN-EP-00001, Addendum 6, SI Accumulator Isolation and Restoration.

C. (1) Both PORVs, BB PCV 455A and BB PCV 456A, will open.

(2) Restore SI Pumps to be capable of injection per OSP-EM-00002, Section 7.1 Restoring SI System.

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator D. (1) Both PORVs, BB PCV 455A and BB PCV 456A, will open.

(2) Restore SI Accumulators per OTN-EP-00001, Addendum 6, SI Accumulator Isolation and Restoration.

Answer: A Explanation: The is a common misconception that for this situation (with COMS Armed) that both PZR PORVs will open due to a failure of the Loop 1 WR T cold . The inputs into the logic are as follows:

T hot T cold WR Pressure PORV A Train 1,2 3,4 BB PT 405 BB PCV 455A B Train 3,4 1,2 BB PT 406 BB PCV 456A Therefore, when Loop 1 T cold Fails Low ONLY BB PCV 456A will be affected.

Per Annunciator 35B PORV open, step 3.3 - IF the PORVs should NOT be OPEN:

3.3.1. IF excessive RCS leakage is indicated, Go To OTO-BB-00003, Reactor Coolant System Excessive Leakage. The report that PZR level is lowering means that the crew will NOT stay in OTO-BB-00003 and transition to OTO-BB-000010, Shutdown LOCA.

This is given in the stem as the entry conditions for OTO-BB-00010, are RO knowledge and not being tested here. OTO-BB-00010 step 10 directs that SI and CCP system be realigned as they have been placed in a lineup for COMS. OSP-EM-00002 section 7.1 is correct as it would restore SI system for injection. OTN-EP-00001 is plausible as it would also met the same strategy of recovering an ECCS system for injection into the vessel but is NOT directed from OTO-BB-00010 and therefore wrong. SI accumulators are pressurized to ~650psig and with RCS pressure at 500 psig they could inject.

Effects on axial flux density of control rod alignment and sequencing, xenon production and decay, and boron vs. control rod reactivity changes Question # 18 (REFERENCE PROVIDED)

Given the following plant conditions:

  • 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> ago, Shutdown Bank A Rod P-4 dropped into the core.

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator Answer: B Explanation:

With Shutdown Bank Control rod P-4 fully inserted, a local Xenon transient began 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> ago.

The Production of Iodine (XE precursor), which is dependent of the number of fissions locally, lowered but so did the burnout of Xenon due to the lower neutron flux. This results in local Xenon concentration spiking over the next 6-10 hours, reaching a peak ~10 hours after the dropped rod.

After this point, local Xenon concentration will lower as less Xenon is produced (less Iodine) resulting in less of a local poison concentration. Less poison encourages neutron flux and which the rising flux there is more neutron leakage resulting in more neutrons reaching NI 41. The results would be a NI 41 reading rising as the xenon concentration lowers.

Due to the malfunction, the crew will be implementing OTO-SF-00001. Specifically, the crew will be at step A11 waiting for I&C to find and fix the cause of the malfunction. Upon the report that the problem has been found and corrected, the CRS will direct performance of OTO-SF-00001 Attachment B per step A12.

ESP-ZZ-00004 is plausible as it is performed concurrently with ESP-ZZ-00006, Incore/Excore Calibration. This is plausible as a quadrant power tilt is occurring from the dropped rod and xenon transient. However, as the Xenon transient is in progress and the prerequisites of ESP-ZZ-00004 require xenon is within 5% of equilibrium, this is not the correct application of this procedure. Correcting the initial problem (dropped rod) is the correct choice which will then correct the QPTR concern.

Question # 20 Operations management is REQUIRED to designate an additional SRO to fulfill the Reactivity Management SRO (RMSRO) position for which of the following situations?

A. Planned load reduction from 100% to 97%.

B. A rapid load reduction due to an emergent plant event.

C. RCS Dilution for Low Power Physics Testing post refuel.

D. The plant is in Mode 6 with portions of the RCS being filled from the RWST.

Answer: C Explanation:

Per ODP-ZZ-00001 Addendum 10, step 2.1.5 states that Designate a Reactivity Management SRO (RMSRO) to direct Reactor Operations whenever reactor power is changed by more than 5 % in one direction. This includes:

  • Reactor startup
  • Lowering power in MODES 1 and 2
  • Raising power in MODES 1 and 2
  • Withdrawal of Shutdown Banks
  • Diluting for Physics Testing post refuel.

Therefore, RCS Dilution for Low Power Physics Testing post refuel is correct. Lowering power from 100% to 97% does not meet the power changed by more than 5% criteria and is therefore incorrect.

ODP-ZZ-00001, step 3.6.1 states The CRS normally performs the responsibilities of the RMSRO during steady state and emergent plant conditions. The CRS may also perform the RMSRO function during reactor startup. Therefore, since this is an emergent power reduction operations management is NOT required to designate an additional SRO to fulfill the RMSRO position.

Step 2.1.12 defines what activities are potential reactivity manipulations due to dilution activities which would require additional briefing and peer check but these dont require a RMSRO. Specifically Filled portions of the RCS and the Refueling Pool (RFP) that have direct access to the Reactor Vessel in mode 6 below 2000 ppm was selected but is incorrect. Since RWST boron concentration is directed per UFSAR 16.1.2.5 for Mode 6 to

NRC Site-Specific Written Examination Callaway Plant Senior Reactor Operator be greater than 2350 ppm there is no way this evolution would result in going below 2000 ppm.

A. Incorrect - 5%power change rule B. Incorrect - an emergent power reduction C. Correct D. Incorrect - Listed as a potential reactivity manipulation due to dilution in step 2.1.12 of addeddum 10 but does not require a RMSRO.

This question involves the application of SR 3.0.2 and SR 3.0.3. First it is necessary to calculate the 25% grace period that is specified in SR 3.0.2. 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> x 0.25 = 18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br />. Since the surveillance is still within its grace period, the remainder of the grace period will be used to perform the surveillance within its specified frequency. The time remaining on the grace period is 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> (18 hours2.083333e-4 days <br />0.005 hours <br />2.97619e-5 weeks <br />6.849e-6 months <br /> - (80-72 hours)) as 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> of the grace period has elapsed by 0800.

Therefore, 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> is the Latest time in which the SR may be completed sat and the specified frequency be met.

A. Correct - see above B. Incorrect - plausible if the candidate calculates the grace period correctly but does not apply the correct starting time of the grace period i.e. assumes the grace period starts at 0800 instead of when the normal 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> was up (i.e 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> ago).
