Subject:
McGuire Nuclear Station Review of Written Licensing Exams
Dear Sir:
Attached are our specific comments on the R0 and SR0 written examinations administered here on March 10, 1986.
In addition, we also have these general concerns:
1.
The first three sections of the R0 and SR0 exams are almost identical
(>80% duplication).
This seems to be inconsistent with the philosophy that there is a different level of knowledge expected of R0s and SR0s.
2.
It appears that the learning objectives stated in our supplied training' material were not used in selection of appropriate questions.
Most questions appear to have been taken from the body of lesson plans and do not relate to the learning objectives for that lesson.
This is inappropriate since our systematic approach to training is based on learning objectives.
Lesson plans contain material that is beyond the expected learning objectives, and we strongly feel that questions on exams should be related to learning objectives.
3.
Many questions are not worded in a straightforward manner, even though they may be technically correct.
Questions of this nature test the candidates' ability to infer what the examiner wants as an answer as much as his pure knowledge.
This leads to candidates having to be overly verbose in their answers to cover any and all possibilities.

Pago 1 MCGUIRE REACTOR OPERATOR LICENSE EXAMINATION 0386 REVIEW GROUP COMMENTS SECTION 1 Question 1.01c Comment We feel that Part C to this question was not specific enough to require the answer indicated by the test key.
Recommendation We recommend that the acceptable answer be either volume flow rate decreases or remains the same.
Justification Lesson Plan:
OP-GA-SPS-THF-FF, page 32 In accordance with the Lesson Plan referenced by the answer key, both answers would be acceptable.
The Lesson Plan reads as follows:
"The positive displacement pump will provide a constant volume flow rate as friction losses increase.
The pump head supplied can take any value at constant flow rate.
When friction losses are high, a backpressure builds up in the system and some fluid leaks back into the pump displacement volume.
Thus, the actual character-istic curve bends to the left at the top,"
In addition, the figure 1.1 of the test is the Ideal pump curve and does not reflect the condition where the curve bends to the left.
Question 1.02b Comment Test answer key reflects wrong answer.
Recommendation Change answer to read " remains the same".
Our OP delta T setpoint is not increased for a T"V" decrease below 100% value T,y,.
Justification McGuire Technical Specifications Section 2.0 Table 2.2-1.
Pcgs 2 Question 1.06a comment We feel this question is beyond the scope of required Reactor Operator knowledge.
Recommendation We recommend this question be removed.
Justification Lesson Plan:
OP-MC-SPS-IC-RVL No Lesson Plan objectives and Lesson Plan does not provide a clear answer to this question.
Question 106b Comment Answer refers to elevated containment temperature conditions only.
Recommendation Recommend answer read "to compensate for reference leg temp-erature changes during normal and emergency conditions".
Justification Lesson Plan:
OP-MC-SPS-IC-RVL RTD's installed on the impulse lines are used to compensate level indications due to the change in temperature of the reference leg.
This compensation will occur during normal and emergency conditions.
Question 106c Comment We feel that " saturated conditions in the core" should be an adequate answer to part c.
Recommendation Accept " saturated core conditions" or any comparable answer for full credit.
Justification The above recommendation fully answers the question asked.
Pcga 3 Question 1.07 comment We feel this question may be somewhat misleading since the first section refers to an ECC calculation (We refer to this as ECP) and the second part refers to a Shutdown Margin Calculation.
Tha question asked relates to the Shutdown Margin Calculation but is no longer part of the ECP Calculation.
Recommendation Accept any answer reflecting that we do adjust our ECP value based on Xenon concentration and that under certain conditions we may take credit for existing Kenon concentration towards our Shutdown Margin Calculation.
Justification Plant Operating Procedure OP/0/A/6100/06.
Question 1.08 Comment We feel that 1/2 of the required answer by the test answer key is not related to question asked.
The question did not ask for when in core life that Plutonium 239 builds in the fastest.
The question only asked for the effects of flux hardening on differential Boron worth.
Plutonium 239 statement is irrele-vant.
l Recommendation l
l Delete the second part of the test answer given for this question l
and allow full credit for the first part which fully answers the question asked.
Justification We feel that, as indicated above, the first part of the test answer given fully answers the question asked.
Question 1.09 comment We feel that the required answer for this question is in too much detail for question asked.
Question asks how decrease in reactor coolant flow will result in a decreaing DNBR.
It did not state list two reasons and explain.
Paga 4 Recommendation We recommend that you accept the first part of the test answer for full credit.
Justification The second part of the test answer is not reflected on training handout MC-THF-CP-46.
The second part of the test answer is beyond the scope of RO candidate's required knowledge level.
Question 1.10 Comment The answer for Steam Generator level will depend on whether the license candidate assumes steady state conditions or
]
transient conditions.
Recommendation We recommend that you also accept the answer " remains the same" for the affected loop and unaffected loop.
This answer would be correct if the license candidate assumed steady state conditions.
The test answer key reflects the correct answer only during transient conditions.
Justification Lesson Plan:
OP-MC-CF-IFE Handout Drawing MC-IC-IFE-1 Question does not specify which conditions are present.
i Question 1.11 l
Comment l
There is no correct answer.
Answer key reflects D to be the l
correct answer which is incorrect for the question asked.
Recommendation Delete question from exam.
Justification No correct answer available.
Pcgn 5 SECTION 2 Question 2.02b Comment Should not require a specific amount of pressure change "100 psi" to get full credit.
Question did not ask how much pressure would change.
Recommendation Accept "NC System pressure increase" for full credit.
Justification "NC System pressure increase" fully answers question.
Question 2.04b comment Answer to part b is incorrect.
The sequencer will not load any more groups since UV relays are reset.
However, load groups can be manually loaded.
Recommendation We recommend that you accept any answer reflecting that the sequencer will stop its loading sequence.
Justification I
Lesson Plan:
OP-MC-SPS-EL-EQB Manual loading is available following a reset of the sequencer.
Question 2.05 Comment Answer key states " SIS" as one of the four required answers.
In the context of this question SIS is referring to both "CLA" and
" UNI" which would be two separate sources of water to the containment sump.
Recommendation Accept any four of the following five sources:
FWST, NCS Break, CLA, UNI, Ice Melt.
Justification 1
Both CLA and UHI are sources of water to the containment sump and are not commonly referred to as SIS.
. =.. _
Paga 6 Question 2.06 Comment Test answer is correct assuming that containment spray has not been reset.
If containment spray has been reset, then the required answer would be greater than or equal to.25 CPCS signal and 3 psig containment pressure signal.
I Recommendation We recommend that you accept either answer as correct.
Justification Lesson Plan OP-MC-SPS-IC-ISE Handout Drawing MC-IC-ISE-5 j
Answer may vary depending upon the license candidate's inter-
]
pretation of the question.
5 Question 2.09a comment Question could be easily misinterpreted.
Likely to receive the following answer:
"During blackout, the B train is isolated from the RV loads".
Recommendation We recommend license candidate receive full credit for answer similar to that indicated in above comment.
Justification Question too easily misinterpreted.
We do not stress the need to understand all the design aspects of plant systems and this question asks why the system was designed in a certain manner.
Question 2.09c Comment Question seems to reflect some system other than McGuire's.
For our plant these valves would fail closed and this would be due to either a loss of air to the valve operator or a loss l
I of power to the solenoid valve.
There is no special reset associated with these valves and the corrective action to restore the valves would depend on what the failure was.
l Recommendation We recommend that this question be deleted from the exam or credit accepted for any answer relating to the restoration of air to these valves or power to the solenoid.

Pcga 7 Justification Lesson Plan:
OP-MC-SYS-RN Handout Drawing MC-SYS-RN-2.
Question 2.17d Comment Answer key states normal pressurizer PORV's.
Low pressure protection at our plant is provided by only two of the three pressurizer PORV's.
(NC-32, 34)
Recommendation Correct answer key to reflect two of the three PORV's.
(32,34)
Justification Lesson Plan OP-MC-SPS-IC-ILE page 19.
Question 2.18a Comment J
Answer key states that a permissive from the sequencer is one of the three required signals.
This is not a required signal.
Recommendation We recommend the following be accepted for full credit:
l.
S signal (3 lb.)
p 2.
>.25 psig from CPCS 3.
Inlet valve / damper open Justification l
Lesson Plan OP-MC-SPS-SY-VX, page 18.
Question 2.21 Comment Question is misleading for the required answers since the question states "other than reducing containment pressure," and containment pressure is reduced by the Ice Melt.
The question appears to be concentrating only on the chemical properties of the Sodium Tetraborate which is in the solution and not on the water itself.
Pcg3 8 Recommendation We recommend full credit be given for the first two answers of the test answer key.
Justification Question appears to only ask why we use sodium Tetraborate in our ice.
The ice would serve as a cooling medium whether or not it contained Sodium Tetraborate.
Question 2.22a, b comment We feel that both these questions are not relevant to Plant Operation and are not covered by Lesson Plan objectives.
Our SSF does not have specifically labeled rooms.
Recommendation We recommend Sections a and b of this question be deleted from the test.
Justification Lesson Plan OP-MC-CP-AD.
Question 2.22c Comment We feel that acceptable answer to this question would be
" maintain saturation conditions in the pressurizer".
Recommendation Allow full credit for answer reflecting saturation conditions in the pressurizer.
Justification By maintaining saturated conditions in the pressurizer we will thereby prevent excessive cooldown and void formation in the reactor vessel.
Pcg3 9 SECTION 3 Question 3.05a Comment The answer key has two incorrect selections and does not include an additional correct selection.
"KRP" and " Battery to inverter to Bus" do not come from a 600 VAC emergency bus.
Recommen'ation We recommend that the answer key be changed to reflect the following answers:
1.
Battery charger to inverter to bus 2.
600 VAC to standby battery charger to inverter to bus 3.
Cross tie between sister DC busses Justification Lesson Plan MC-SYS-EPL-1 and OP/0/A/6350/lA.
Question 3.06 Comment Part a says rod control system but the pulser is proportional to combined error signal not the NC system temperature error only.
Part b says rod control system but is asking for an answer in the reactor control system which'is a different system.
The rod control system does not use the power mismatch circuit.
Thi's circuit is part of the reactor control system.
Recommendation We recommend that both parts a and b be deleted from the exam.
Justification Lesson Plan OP-MC-SPS-IC-IRE Handout Drawing MC-IC-IRE-3 Lesson Plan OP-MC-IC-IRX Hendout Drawing MC-IC-IRX-2 Question misleading due to terminology used.
Question 3.lla comment Answer key reflects the wrong answer.
Pcg3 10 Recommendation We recommend answer read as follows:
Right side - manual loader output (demand)
Left side - valve position (feedback)
Justification Our controller setup is as listed above.
Question 3.11b Comment Wording of the question is confusing.
We have no setpoint position on our controller.
The setpoint is a pot setting and not a switch position.
Recommendation We recommend full credit be given for description of auto and manual positions.
Justification Question is misleading or may be referring to a different type of controller than the one we use.
Question 3.13a Comment Answer key indicates "S signal after LOCA".
Correct answer would be S signal or p ase A isolation.
j T
Recommendation We recommend you accept S signal or phase A isolation as T
correct answer.
Justification signal.
LOCA is not the only thing that will generate an ST l
Pago 11 Question 3.13b comment
" General type of fire protection status alarms" is unfamiliar terminology.
This results in confusion as to what the question is asking.
Answers other than those listed may be:
OAC alarms, Alarm bells, Annunciator alarms, EFA panel alarms.
Recommendation We recommend that this question be deleted.
Justification Due to terminology used, answers given may not correspond with those listed on test answer key.
Question 3.14 comment Question refers to a " Gain Switch" which is incorrect termino-logy.
We have a Gain Pot and a range switch.
Also, question refers to the wrong figure.
Figure should be 83.1 and 83.2.
Recommendation We recommend that you accept the answer for either gain pot, purpose or range switch purpose.
Justification Lesson Plan OP-Mc-IC-ENB.
Question 3.19b comment We feel this question is misleading.
The answer provided in-dicates the status of DEH (auto or manual) prior to the automatic runback occurring.
The question asks about automatic and manual runbacks.
In order to have a " manual" runback, the operator must manually close the valves.
Recommendation We recommend that this question be deleted from the test.
^
Pcga 12 Justification Terminology used is misleading for answer required.
Question 3.20 Comment Operations has nothing to do with the lights on the NC pump panels.
Our procedures do not address this panel or require the operators to check this panel prior to starting NC pumps.
This indication is the responsibility of the Relay Department.
The operators have UV and UF status lights in the control room which they use.
Also, the examiner responded to inquiries about this question during the exam and stated that this was not the panel located in the control room.
Recommendation We recommend this question be deleted from the exam.
Justification See comment above.
Question 3.21a Comment Test answer key is generally correct however, if license candidate specifies train related pumps the following may also l
be included as part of the answer:
Train A CF to CA Nozzle Valves (CF126 thru 129)
Train B CF Cont. Isol. Bypass (CF134 thru 137)
Recommendation We recommend that if license candidate includes above information as part of the answer, it be considered correct.

Pcg3 13 Question 3.22a comment Figured referred to in this question does not reflect the correct control circuit now used for the NCP oil lift pumps.
Recommendation We recommend that you remove " Safety Breaker" from required answer or give full credit for interpretation of diagram by license candidate.
Justification License candidate knowledge may be more current than information used on Figure 91.1.
Question 3.23 comment Question is technically incorrect.
1LXG is not a power supply to C heater group.
Recommendation Question be deleted from exam.
Justification Reference OP-MC-PS-IPE Training Handout MC-IC-IPE-4.

Pcg] 14 Question 4.07 comment of the available choices to this question, none are totally correct.
Both choices A and D are partially correct.
Recommendation Accept A or D for full credit or delete question from exam.
Justification McGuire Station Health Physics Manual Section 16.10, page 4.
Question 4.11a comment Question requires specific numbers contained in the subsequent actions of a procedure.
We do not feel that the license candidate has a need to know the subsequent actions of a procedure to that extent.
Recommendation We recommend that you accept a broader range of time than the times indicated in the procedure (i.e. 2 to 10).
Justification We do not require memorization of subsequent actions since the operators are required to use the procedure during all subsequent steps.
l Question 4.16 consnent The question asks for the parameter used to determine if a steam Generator is faulted.
Question does not ask how this parameter changes but the answer requires the parameter and how it changes.
Recommendation We recommend'that the parametcr only be accepted for full credit.
Justification Answer requires more than the question asks.
Pcg2 15 Question 4.17 comment The question is contradictory.
It states Diesel Generator running and no automatic actions occur on the board which is inconsistent.
D/G running indicates that the sequencer has actuated and therefore there would have had to be some automatic actions on the control board, and upon sequencer actuation the opening of pump breakers would require the removal of sequencer control power and this is inconsistent with the answer.
Recommendation We recommend that this question be deleted from the exam since there are no logical assumptions that can be made.
Justification The question is contradictory.
Question 4.22 comment Question could be confusing.
Question does not state which control rod lost it's position indication.
If the rod which lost it's position indication is fully inserted then the reactor trip breakers are not required to be opened (question did not state that the affected rod was in the shutdown bank).
Recommendation j
If the candidates assume the affected rod is fully inserted, then the reactor trip breakers are not required to be opened, this would be a correct answer based on the assumption.
If the candi-dates assume the rod was not fully inserted, then the reactor trip breakers must he opened.
Either should be accepted for full credit based on the assumption.
Justification Question could lead to two possible answers based on interpre-tation by candidate.

Recommendation We recommend that you also accept the answer " remains the same
for the affected loop and unaffected loop.
This answer would be correct if the license candidate assumed steady state conditions.
The test answer key reflects the correct answer only during transient conditions.
Justification Lesson Plan OP-MC-CF-IFE Handout Drawing MC-IC-IFE-1 Question does not specify which conditions are present.
Question 5.13 Comment Answer requires " dilution" for full credit whereas the question only asks for the change in boron.
Recommendation Recommend full credit be given for the PPM change of 52-56.'
Justification Question did not ask for dilution or boration simply the required change.
Question 5.18 Comment In our training program we stress nucleate boiling as an effective heat transfer method.
We do not place any importance on the difference between subcooled nucleate boiling and bulk nucleate boiling.
Pcg2 4 Recommendation We recommend that the correct answer should be:
1)
Convection 2)
Nucleate 3)
Film 4)
Nucleate 5)
Film Justification The training program does not require that the license candidate be familiar with the differences in bulk and subcooled nucleate boiling and since it is extremely difficult to visually display partial film boiling, we do not place a high level of importance on the effects of partial film boiling.
Question 5 19b comment Answer to the question does not include Regions I and II.
Also based on the figure, it is hard to determine if the curve reaches the POAH.
Answer key says "POAH" is the correct answer.
The graph for reactivity does not reflect that the point of adding heat has been reached.
Recommendation We recommend that you accept Regions I and II as correct answers.
Justification Lesson Plan OP-MC-SPS-RT-RK and figure 38 of the exam.
Question 5.21 Comment Answer key indicates that the candidate must say that Samarium is a stable isotope for full credit, but the question does not indicate the need to state this fact.
Recommendation We recommend full credit be given for the answer "both the production and removal rate are proportional to power level".

Recommendation We recommend that the parameter only be accepted for full credit.
Justification Answer requires more than the question asks.
Question 7.17 comment The question is contradictory.
It states Diesel Generator running and no automatic actions occur on the board which is inconsistent.
D/G running indicates that the sequencer has actuated and therefore there would have had to be some automatic actions on the control board, and upon sequencer actuation the opening of pump breakers would require the removal of sequencer control power and this is inconsistent with the answer.
Recommendation We recommend that this question be deleted from the exam since there are no logical assumptions that can be made.
l Justification The question is contradictory.
Question 7.20
(
comment Question could be confusing.
Question does not state which control rod lost it's position indication.
If the rod which lost it's position indication is fully inserted then the reactor trip breakers are not required to be opened (question did not state that the affected rod was in the shutdown bank).
Page 14 Recommendation If the candidates assume the affected rod is fully inserted, then the reactor trip breakers are not required to be opened, this would be a correct answer based on the assumption.
If the candidates assume the rod was not fully inserted, then the reactor trip breakers must be opened.
Either should be accepted for full credit based on the assumption.
Justification Question could lead to two possible answers based on interpre-tation by candidate.
McGuire Nuclear Station Technical Specification 3.1.3.3.
Question 7.25 comment The answer for this question lists four possible alternative actions that could be taken when in accordance with procedure there are five possible actions.
Recommendation We recommend that you include " manually trip turbine" as a fifth alternative and accept any four alternatives for full credit.

Page 15 SECTION 8 Question 8.01 Comment Question gives two possible choices that could both be considered correct in accordance with Station Directive 3.8.1.
Recommendation We recommend that you accept A and/or B as the correct answer.
Justification Station Directive 3.8.1, page 4, number 5.
This states that the responsible person could be the most senior person in that group.
This person would be the Superintendent of Operations during day shift and the Shift Supervisor during night shifts.
Question 8.09 comment This question gives two possible choices, both of which are correct.
Choice A says "for more than one shift" which would include a shift change.
Choice B says "past a shift change".
Recommendation
~
We recommend that you accept A and/or B as the correct answer since A would include B.
Justification The statement "more than one shift" indicates that a shift change has taken place.
Question 8.21 l
Comment _
l This question is requiring a specific number from within the body of a Station Directive.
We feel that this is inappropriate since a procedure would be in use at this time to direct the required actions.
