Original question: #43 062A 1.01 062A1.0l Question 43 Recommend deIetin the question Reason:
The intent of this question was to ask how energizing the Heater Group for A Train would affect the loading of the small Diesel Generator (DG). This question has a typographical error that actually asks how energizing a B Train Heater Group would affect the loading an A Train DG. The question also asks if energizing this heater group is allowed by procedure.
First part of the question asks, IF the PRZR HTR GROUP BACKUP is energized, THEN the 1C DG 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> load rating will/will not be exceeded.
The answer to this question is the 1 C DG will NOT be affected since the load that is being started is on the opposite train. The problem with this statement is that the load cannot be energized since there is no power to B Train anyway. That train is de energized due to the I B DG being tripped.
The second part of the question asks if, energizing the I B PRZR HTR GROUP BACKUP IS/IS NOT allowed lAW EEP-l, Loss of Reactor or Secondary Coolant.
This question is irrelevant since the load in question has no power and cannot be energized at this point in time. An assumption would have to be made that power can be made available. Appendix E does not allow the candidate to make that assumption since that information is not stated in the stem. The candidate is left to answer this question based solely on the information given. (See Appendix E excerpt below)
Further information In the answer to the first part of the question, the choices of C and D would be the only viable choices since the load on the 1 C DG is not affected by a component on the other train. This eliminates choices A and B as a correct answer. Further, choices C and D can NOT be considered correct for the following reasons:
1.
For C to be correct, the candidate has to ignore the fact that the lB heater Group has no power available. Operating the handswitch for the lB PRZR Heater Group is allowed in EEP-1.0, but technically the candidate would NOT be energizing the heater group by operating the handswitch since there is no power source to this set of heaters.
2.
For D to be correct, energizing the heater is technically allowed by EEP-1.0, but the heater cannot be energized at this time since the bus is de-energized. EEP-1 does not have a step to start the 2C DG and the 2C DG would have to be started to allow this heater group to be energized. So while it is allowed it cannot be accomplished completely in EEP-1.0. Therefore the candidate would have to assume the 2C DG is started to allow D to be correct.

Original question: #43 062A1.01 Appendix E When answering a question, do not make assumptions reardina conditions that are not specified in the question unless they occur as a consequence of other conditions that are stated in the question. For example, you should not assume that any alarm has activated unless the question so states or the alarm is expected to activate as a result of the conditions that are stated in the question. Similarly, you should assume that no operator actions have been taken, unless the stem of the question or the answer choices specifically state otherwise. Finally, answer all questions based on actual plant operation, procedures, and references. If you believe that the answer would be different based on simulator operation or training references, you should answer the question based on the actual plant.

- c. If it is determined that there are two correct answers, both answers will be accepted as correct. If. however both answers contain conifictina information, the question will likely be deleted. For example, if part of one answer states that operators are required to insert a manual reactor scram, and part of another answer states that a manual scram is not required, then it is unlikely that both answers will be accepted as correct, and the question will probably be deleted.
If three or more answers could be considered correct or there is no correct answer, the question shall be deleted.
Background:
A typographical error was missed during the review and validation of this question.
Conclusion The facility recommends deleting the question from the exam since there is no correct answer.

A - Incorrect. The first part is correct (see B). The Second part is incorrect (see B).
Plausible since the procedure does state that in an emergency, the design of the electrical system has determined that a slight overload may exist after a LOSP and a LOCA. This is acceptable as long as the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> rating is not exceeded. Also, the Basis of TS 3.8.3 allows the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> limit to be exceeded for up to 300 hour0.00347 days <br />0.0833 hours <br />4.960317e-4 weeks <br />1.1415e-4 months <br /> per year but EEP-I forbits exceeding the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> limit. Confusion may exist as to which one or if both the continuous and/or the 2000 ratings may be exceeded for a period of time.
Also, the continuous load limit and the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> rating values may not be remembered properly. However, the procedure states that MANUAL loading above EITHER the continuous or 2000 rating is not allowed. Confusion could exist as to what the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> load allows, i.e. it does not allow overloading above the limit for any period of time as the continuous load limit does.
B
- Correct. The continuous load limit is 2.850 MW, and the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> load limit is 3.100 MW. 2.860+0.30=3.16MW > continuous load limit.

Under these circumstances, diesel generator loading may be raised not to exceed the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> load rating limit (i.e. 3.1 MW for small DGs, 4.353 MW for large DGs...).
C - Incorrect. The first part is incorrect. Plausible, since the continuous load limit and the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> rating may not be remembered properly, and/or the load in MW of the przr heaters may be confused with other smaller loads. The large DGs have a higher load limit of 4.075 & 4.353 MW for continuous and 2000 hr rating respectively. The second part is incorrect (see A).
D
- Incorrect. The first part is incorrect (see C). The second part is correct (see B).
Plausible, since the continuous load liming is already exceeded, and manual loading above the continuous load is not allowed, even though automatic loading above the continuous load limit is allowed in an emergency.
FSD, Diesel Generator System 3.1.6 Interface Requirements The only time during operation (other than design basis accidents) that the diesel is intentionally loaded above its continuous rating is during Technical Specification surveillance testing when the diesels are loaded to their 2000h ratings (4353 KW for the large diesels and 3100 KW for the small diesels).
APPENDIX B STATiC LOADING OF THE DIESEL GENERATORS 8.
2.0 INTRODUCTION
During some design basic events, diesel generator 1 C is loaded above its continuous rating by less than 5%. However, this calculated loading above the continuous rating is acceptable since the diesel loading still meets the criteria contained in Position C.2 of Safety Guide 9 (Reference 6.7.028).
G.4.3 Potential Diesel Generator Overload The potential exists for DG overload if the LOSP is followed by a
LOCA after step 2 of the LOSP sequencer has been energized.
In those cases, the DG will be loaded with the Reactor Cavity Cooling Fan (13 Kw) and the CRDM fan (84 1(w) in addition to the ESS loads, and the operator may have to remove selected loads if the DG is loaded above its rated capacity.
This situation does not constitute a concern given the existing guidance in the plant procedures which provides the operator with guidance for reducing the DG loading if it is above rated capacity.
EEP-1 LOSS OF REACTOR OR SECONDARY COOLANT Revision 29 ATTACHMENT 4 VERIFYING 4160 V BUSSES ENERGIZED I Verify 4160 V busses energized.
CAUTION: IF a DG is already operating above its continuous load rating, THEN additional manual loads should not be added. Unanticipated plant emergency conditions may dictate the need to load the emergency diesel generators above the continuous load rating limit (i.e. 2.85 MW for small DGs, 4.075 MW for large DGs). Under these circumstances, diesel generator loading may be raised not to Friday, April 16, 2010 10:01:44 AM 2

A1.01 Significance of D/G load limits 3.4 3.8 Match justification:
In this question parameters are provided which must be evaluated to predict if the DG will be overloaded if a load is manually started. The size of the load in MWs must be known and the load limit must be know to predict if the load may be started and if it will exceed the design limits. The significance of the load limits must be understood, since the continuous limit may be exceeded in an emergency without expected damage to the DG, but the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> load limit may not be exceeded for any reason.

Original question: #68 G2.4. 16 G2.4.16 Question 68 Recommend acceQting A and B as correct answers Reason:
Choice A is a subset of Choice B since ECP-O.O step 24 through 28 would be conducted in both cases and the next encounter with the direction to MONITOR the Critical Safety Function Status trees is only after ECP-O.O is completed in its entirety. At no time during the performance of ECP-O.O would a new instruction to MONITOR the CSF Status Trees be encountered.
Background:
In the stem of the question, the following information is provided:
Attempts to restore power to any 4160V bus from any source per the step, Restoration of power to any emergency bus, have all been unsuccessful.
This statement establishes that all actions of step 5 have been completed without success; therefore continuance within ECP-O.O until a transition to ECP-O.1 or ECP-O.2 is directed when power is restored. The initial conditions provided establish the position within the procedure to be at a step below the Caution above step I that provides the initial guidance to monitor the CSF status trees for information only.
Step 6, then establishes a Continuing Action that Step 24 should be implemented upon a restoration of any bus. Steps 6 through 23 will be repeated until power is restored OR conditions have degraded to a condition were SAMG entry is required.
When power is restored steps 24-29 are completed and ECP-O.O is exited.
If power is never restored or restoration is significantly delayed, then steps 11-24 are repeated until either entry into SACRG-1 is required or power is restored. No additional instructions to monitor CSF status trees are provided while within this DO-Loop. Therefore, ECP-O.O actions would continue until power is restored, in which case a transition to step 24 would occur and step 24-29 would be completed and ECP-O.O would be exited. This endpoint is the same condition resulting from the conditions in choice A.
It is only upon entry into ECP-O.I or ECP-O.2 that the NEXT instruction to monitor CSF status trees would be encountered. That instruction is provided in the CAUTION prior to the first step at the beginning of both procedures, ECP-O.1 and ECP-O.2. (See caution below)
Page 1 of3
Original question: #68 G2.4.16 CAUTION:
Critical cafety function tatua treea chould be monitored for information only.
No Function Rectoration Procedure chould be Implemented until completion of otep 12.
This is the NEXT encounter with instruction to monitor CSF status trees, therefore the resultant flowpath would have been a continuation of ECP-O.O until instructed to monitor CSF status trees.
Under both circumstances, ECP-O.O actions would continue and complete step 24 through 29. Under both circumstances the transition to the subsequent Stabilization/Contingency procedures occurs. Choice B encompasses the same steps intended by answer choice A.

A - Correct. Remaining in ECP-0.O until power is restored is correct since there are nn CSFs required to be entered while in ECP-0 per the caution at the beginning of the procedure.
CAUTION: Critical safety function status trees should be monitored for information only. No function restoration or other procedure should be implemented during a loss of all AC power.
B

- Incorrect. See A above SOP-O.8, Emergency Response Procedure Users Guide, Version 18.0 4.2 Applicability [of the CSFSTs: FRPsI The user should begin monitoring the CSFSTs when directed by EEP-0 or upon transition from EEP-0. The CSFSTs are not monitored initially because the ERPs are already directing the initial action required to protect the barriers. If the user enters ECP-0.0. the CSFSTs should be monitored for information only. The Function Restoration Procedures assume that at least one train of safeguards busses is available. If all AC power has been lost, ECP-0.0 will provide the appropriate actions to protect the barriers.

(CFR: 41.10 I 43.5 145.13) RO 3.5 SRO 4.4 Match justification: This question requires knowledge of the EOP hierarchy to answer correctly. The EOP heirarchy involves the FRPs being implemented as the highest priority procedures except in certain cases (early in E-0 and during loss of all AC they are not implemented), also, in the event of SAMG entry requirements, there are only a few entry points from the ERG network, and the transition is directed at the specific procedure steps.
When SAMG entry is required, it takes priority over the EOPs and FRPs.
