QUA0 CITIES 1 8 2 REACTOR OPERATOR AND SENIOR REACTOR OPERATOR REPLACEE NT EXAMINATION REACTOR OPERATOR AND SENIOR REACTOR OPERATOR REQUALIFICATION EXAMINATION OCTOBER 14. 1986 1.12 Facility Comment:
Another answer that should be acceptable for this question is to maintain proper reactor water level to prevent carry under. The Reactor Vessel and Internals text lists carry under as a factor that will lower recirc pump NPSH. Pages 14 and 15 of this text are attached. (Also applicable to replacement question 5.11 and requalification questions 1.06 and 5.05).
Resolution:
Cross referenced to R0 1.12 & SR0 5.11 Replacement R0 1.06 & SR0 5.05 Requalification Connent noted but not accepted. The items requested to be included are already referred to in the answer, i.e. maintain proper water level to prevent carry under. This is addressed with the answer referring to low reactor vessel water level trip.
No change to the answer. key will be made.
1.14 Facility Comment:
QCHPS is currently using the General Electric BWR Academic Series Heat Transfer and Fluid Flow for instruction in this area. This material includes "deration of power increase" as a factor for PCI failures and should also be considered an acceptable answer, as it is synonymous to the items listed on the key. A copy of page 9-47 is attached. (Also applicable to replacement question 5.13 and I requalification question 1.08.)
f Resolution:
Cross referenced to R0 1.14 & SRO 5.13 Replacement R0 1.08 Requalification i
Comment noted and accepted. "Ouration of power increase" will be added to the answer key as an additional correct answer. Answer point breakdown remains unchanged. Page 9-47 will be added to the reference along with QC.LIC-0201-2, Nuclear Fuel Lesson Plan page 20.
2.03.c. Facility Comment:
This question is extremely confusing because it is not clear what the status of the flow converter upscale trip unit is. The question I
~
states that the units are upscale, yet also states that the flow is less than 108%. The trip setting for this at QCNPS is 110%. If the student assumes an actual upscale trip is present, the answer key is correct in specifying a rod block exists, however, if the student merely assumes it is a high reading and a trip does not exist, since the setpoint has not been reached, then no trip is the correct response. Apparently several candidates questioned the examiners on this and were left with different impressions. In this case, either no trip or rod block should be considered correct, however, half scram should be considered erroneous. Page 4 of the APRM lesson plan is attached to describe the trip. (Also applicable to replacement question 6.01 requalification questions 2.02 and 6.01.)
Resolution:
Cross referenced R0 2.03 & SR0 6.01 Replacement R0 2.02 & SRO 6.01 Requalification Conment is accepted. The answer key will be changed to "no reactor protective system action" as would be the case if the flow units failed to the 108 or 107% position. When questioned during the exam it was stated the flow units fail upscale to 108%. Point breakdown remains unchanged.
. 2.06 Facility Comment:
Parts of this answer are in error and another auto start signal at e
2000 R/hr drywell radiation should be added. The reactor building ventilation trip setting is 3 mR/hr, vice 10 mR/hr, and the low reactor water level setting is +8", vice -8". Pages 34 and 46 of the Primary and Secondary Containment text are attached.
Resolution:
Comment is accepted. The answer key will be changed to reflect the answers in the material for the Primary and Secondary Containment vice the answers from the reference material for SBGT system lesson plan. The total number of possible answers will be increased from five to six and the setpoints will reflect the change. The point breakdown will not be effected. The question will be reworded to reflect the six possible answers. QC.LIC-1600-1, Primary-Secondary
- Containment lesson plan page 34 and 46 will be added to the reference.
l The original reference will be deleted due to the conflicting information.
2.07.b. Facility Comment:
This question asks what may be calculated by turning the switch to l COUNT. This may be answered by stating that the number of LFRMs '
inputting to the RBM may be calculated. Stating that 1 LPRM = 1 volt is not asked for and should not be required. (Also applicable to requalification question 2.03) 2 1

~
5 .
Resolution:
Cross referenced to R0 2.07.b Replacement R0 2.03.b Requalification Comment accepted. Because the HOW was not asked for, "Can be calculated by using 1 volt per operating input" will not be required for full credit. The point value for the second portion of part 'b.' will be decreased by 0.5 points. Section and test values for both the RO replacement and requalification will be adjusted accordingly.
2.09 Facility Comment:
This answer key assigns a point valve of 0.5 pts to the statement
" coolant and baron" when discussing improper mixing. If a candidate discusses improper mixing, he should not be penalized this point value for not saying " coolant and boron", since this is implied in the discussion of improper mixing. (Also applicable to requalification question 2.05).
Resolution:
Cross referenced to R0 2.09 Replacement R0 2.05 Requalification Comment is not accepted. It cannot be assumed that the candidate knows what is being mixed i.e., coolant and boron or hot and cold water etc. Therefore, the answer key will not be changed.
3.07.a. Facility Comment:
" Low speed limit" should not be required in this answer. The question asks for the component that is limiting and stating the
" Master Limiter" sufficiently answers this question. (Also applicable to replacement question 6.09 and requalification question 6.06.)
Resolution:
Cross referenced R0 3.07 & SRO 6.09 Replacement
' SR0 6.06 Requalification Comment is accepted. The answer key will be changed to indicate that " Low speed limit" is not required for full credit. The point value is unchanged.
3.10 Facility Comment:

Cross referenced RO 3.10 Replacement RO 3.06 Requalification Comment is accepted. "PCIS Group Isolation will be moved to part f.
Also after further investigation it was noted that some of the ECCS systems had been omitted. LPCI Loop Select Logic will initiate, EDG h will start, and CS, after 8.5 minutes, will start at -59".The question These three items will be added to the answer for part e.
point value remains unchanged. The following will be added tc the reference QC.LIC-1400 Core Spray page CS-13, QC.LIC-1000-1 RHR page 42.
3.11.b. Facility Comment:
The exact title of this alarm tile should not be required. If a student states that the indication is an alam on his control panel that should be sufficient. (Also applicable to replacement question 6.10 and requalification questions 3.07 and 6.07)
Resolution:
Cross referenced to R0 3.11 & SRO 6.10 Replacement R0 3.07 & SR0 6.07 Requalification Coment not accepted due to the fact that there are several alams associated with the Control Room H&V, including a major trouble alarm for the standby H&V system. Therefore, it is required the operator know this specific alarm.
, 4.04 Facility Comment:
This question asks for the imediate action steps that would be taken to control the reactivity addition. Parts 5 and 6 of the answer go beyond the required actions to control the reactivity.
(Also applicable to replacement question 7.04 and requalification l

. 3 4.06 Facility Comment:
This question asks for three actions to be performed and one of the answers listed in the key is " refer to the abnormal procedure". The .
actions listed in this procedure should also be considered correct.
Therefore, insert the drive to its full in position and electrically .
disarm the drive in and drive out solenoids should be added to the answer key. A copy of QOA 300-3 (INABILITY TO DRIVE A CONTROL ROD; UNCOUPLED CONTROL ROD) is attached. (Also applicable to requalification ;
question 4.06).
Resolution:
4 Cross referenced R0 4.06 Replacement RO 4.06 Requalification Comment is accepted. Since the question did not specify actions ;
required by QGP 1-2 and these two answers are Immediate Operator Actions in Q0A 300-3, these two answers will be added to the answer key for both the Replacement and Requalification exam. Point value remains unchanged.
4.08 Facility Comment:
To answer this question to the answer key req'uires, to a certain extent, the memorization of several form numbers or names that are in the rod sequence book provided to the operator. This memoriza-tion is not necessary or encouraged at QCNPS. In answering this question the following points are provided to allow candidate responses to better be evaluated and credit given appropriately.
Copies of QTP 1600-S2 and S3 are attached as well as a copy of QGP 4-1.
- 1. QTP 1600-S2 Control Rod Sequence Review Sheet is the first sheet of the rod sequence book. If candidates describe signature requirements on the first page of the book, this is the form that is being referred to. Answers I and 2 of the answer key are affected by this.
- 2. QTP 1600-53 Control Rod Sequence Sheet is the form used for
- the bulk of the book. Each page describes the movement of a step. This form is referred to in answer 3.
- 3. A caution on page 6 and page 8 of QGP 4-1 states the NS0's responsibility in verifying proper movements and documentation.
This is accomplished on QTP 1600-S3, as described in QGP 4-1, I
and should also be considered as a correct response.
- 4. QTP 1600-S1 through SS have been attached so the examiners
' grading these exams may better understand QCNPS's control on rod sequencing and fairly evaluate candidate responses. (Also
' applicable to replacement question .7.07 and requalification question 7.05)

Resolution:
Cross referenced to RO 4.08 & SRO 7.07 Replacement SRO 7.05 Requalification i Comment is partially accepted. The comment on the candidate memorizing from numbers is a valid point but was not required for credit. Portions of the answer not required for credit are inclosed in parenthesis, the form numbers are so marked. Item 1 is accepted. Credit will be given if the candidate specifies "the first sheet of the rod sequence book".
Item 2 is not accepted because the question is looking for the approvals not the description of the movements of a step. Item 3 is not accepted because the question is asking for verification before rod movement,not checks during rod movement. Item 4 is noted.
4.09 Facility Comment:
The answer key lists the six items from QAP 300-2 but fails to include the items addressed in the note imediately after the six items. This note concerns non-professional reading material and radios or television. These should be considered appropriate answers. A copy of page 7 of QAP 300-2 is attached. (Also applicable to requalification question 4.08)
Resolution:
Comment is partially valid since the referenced NOTE gives examples-of actions which would distract the operators and is forbidden in item (3). Answer No. 3 will be modified to read as follows:
(3) Card playing, games, or other distractions from prescribed duties.
(Will also accept " reading Non-Professional reading material" or
" Utilizing unauthorized radios or TV" instead of "other distractions").
Credit will not be given for "other distractions" and the items in l parenthesis .
I 4.12 Facility Commient:
Items 2, 6, and 7 of the answer to this question are portions of a i group I isolation. A response of verifying a group I isolation should, therefore, be sufficient for these three items. Also, two other automatic actions occur which should be considered as correct responses even though they are not listed in this QOA. These actions are: 1) Off-gas sample vial box suction valve closes, and
- 2) off-gas line drain valves (5408's) close. Page 8 of the Process Radiation Monitor System text is attached. (Also applicable to replacement question 7.05.)
6 i - ~! '
t _
Resolution:
Cross referenced to R0 4.12 & SRO 7.05 Replacement Conwent is not accepted, because: One the procedure referenced does not list the automatic actions as verify a group 1 isolation and it is not assumed the candidate is aware of items 2, 6 and 7 when he/she state verify group 1 isolation. Two the alternate answers requested are not in the procedure and, therefore, will not be accepted and if list will be counted as wrong additional information.
5.07 Facility Comument:
In part a of this answer, the second sentence should not be required for full credit. The question is adequately answered with the first sentence.
In part b, the change may be attributed to an increase in slowing down length vice an increase in thermal diffusion length.
In part c, a discussion of increased leakage, due to the increased void content, is also acceptable. (Also applicable to replacement question 1.08 and requalification questions 1.03 and 5.02)
Resolution:
Cross referenced to SRO 5.07 and R0 1.08 Replacement SR0 5.02 & R0 1.03 Requalification Cmunent is partially accepted. Comment for part a is valid and the answer key will be changed to indicate the second sentence is not required for full credit and the point value will be redistrib-uted to the remainder of the part a answer. The comment for part b is not valid, the control rods absorb thermal neutrons not intermediate neutrons as explained by the refereace material. The comment for part c is noted but no change to the answer key is required. Paraphrasing is acceptable as long as the candidate understands the effects.
5.09.a. Facility Comment:
The term APLHGR is considered acceptable in place of MAPLHGR (actual) at QCNPS and credit should not be taken off if the term is used.
Apparently this is acceptable to the examiner since APLHGR is used in part b. of this question. (Also applicable to requalification question 5.03)
Resolution:
Cross referenced to SRO 5.09 Replacement SRO 5.03 Requalification Comment is accepted. APLHGR will be accepted as the same meaning as MAPLHGR actual.

6.02 Facility Comment:
A lock-up of the pneumatic feed reg valve is affected by denergizing an air supply solenoid valve on its air supply. While a loss of power to this solenoid is not considered a lock-up signal, it will cause the valve to lock-up. Answers addressing this should not be considered incorrect. Q0A 600-2 is attached to describe this as well.
Resolution:
Coment is accepted. The answer supplied in the reference material will be added to the answer key as another required answer for full credit. The point value will be increased by 0.25 for the part of the answer and section and test point values will be adjusted accordingly.
6.04 Facility Commient:
Part a of this question should be removed from the test. The information for this question was found in the " Instructor's Personal Notes" section of the lesson plan and is presented to generate student interest in the subject only. Students are not provided with a copy of these pages. In our course we provide students with texts of the content / skills section. Here a reference is made of these, but even at that they are not listed and only mentioned that they may be found in the FSAR. This is in the background section of the text and is not infomation a student is required to know. Pages 2 and 3 of this lesson plan are attached.
In part c of this question the first two portions are erroneous since the station has implemented the E0P's. While the lesson plan still indicates material from the former QGA's, it is not an operational guidance and the correct answer should be as directed by the QGA 100 block. The QGA direction takes precedence over anything in a lesson plan. Page 3 of QGA 100-3 is attached.
' Finally, the last part of c sounds as if we have only two ARI buttons.
i
!
- In fact we have two pairs of buttons, either or both pairs may be utilized. Actions that occur when these buttons are actuated are described in the ATWS lesson plan as referenced, however, the fact
' that they remain energized for 30 seconds is less significant than the action they cause. Saying that the valves remain energized for ,
30 seconds should not be required. Instead this credit should be placed on what occurs when the buttons are actuated to effect rod insertion. Each channel (pair of buttons) will energize three solenoid operated valves to remove air from the scram air header causing the scram inlet and outlet valves to open and instrument volume vents and drains to close. (Also applicab.le to requalification question 6.03.)

Comments partially accepted. .For part a. This comment is not accepted f because it is stated in the lesson plan that attention will be focused l on transient situations which have a relatively high expected frequency of occurrence. It then states the seven transients listed in the answer key are the ones that attention will be focused on. This is considered part of the design bases for the ATWS system. For part c., regarding the first two portions this comment.is not accepted because QGA 100 states the same information. However, the point distribution will be changed due to examiners error in locating the partial credit. As to the comments on the last part of c, they are partially accepted. That portion referring to the implication of only two valves is wrong. The question did not ask how many pushbuttons are available but how it is initiated, and this is where two pushbuttons must be depressed, for a division, simultaneously. The portion regarding the " energized for 30 seconds" is accepted and will not be required for full credit. The portion regarding the expected actions is accepted. The following will be added to the answer key for part c and will be required for full credit: "To remove air from the scram a ri header and cause the scram inlet [0.25] and outlet valves to open [0.25] and the instru-ment volume vent and drains to close [0.25]." The question and section point valves will be adjusted accordingly. Page 2 will also be added to the reference.
6.06 Facility Comment:
If this question is to be kept in an exam bank, the term " bypass" in part c should be changed to " equalizing" to be more consistent with QCNPS terminology and to prevent future examinee confusion. (Also applicable to requalification question 6.04.)
Resolution:
Cross referenced to SRO 6.06 Replacement SR0 6.04 Requalification Comment noted. The word bypass will be replaced with equalizing to eliminate future confusion.
lI 6.07.b. Facility Comment:
Most examinees will interpret this question as a norwal power reduction of 10% power. In this case the EHC system will respond to produce the following correct answers:
- 1. 40%
- 2. 932 psig
- 3. 1800 RPM
- 4. 0%
- 5. 40% (Not applicable to requalification question 6.05.)
These answers are correct and should be accepted. Due, however, to interaction with the examiners, some examinees may have responded as described in the key. For this reason these answers should be 9
m ---- , , , _ _ . --,--e----e-,,-.-,e--------ww---, , - - , , - - --w-------- - - - -m- - --------,g g-
acceptable for full credit with the exception of b.2. In this case, the reactor pressure would remain at 935 psig. The close biase is not significant enough to retard the opening of the bypass valves to cause reactor pressure to increase as described in the answer key.
This scenario however, does not depict nomal QCNPS operation since it assumes the plant is not paralleled into the Commonwealth Edison System, thereby allowing drastic turbine RPM changes. (Also applicable to requalification question 6.05.)
Resolution:
Cross referenced to SRO 6.07 Replacement SRO 6.05 Requalification Coment is accepted. Due to the confusion of the candidates on this question the question will be graded in accordance to the candidates assumptions. If the candidate answers assuming load rejection the existing answer key will be utilized, if the candidate assumes a power reduction than the facility 2nswers will be used. If the candidate assumes the unit is still paralelled with another facility an additional answer will be generated and added to the key.
Additionally the word " reduction" will be replaced with " reject" and a statement of the only unit on the grid will be added to the question preface. The point value remains unchanged.
7.01.b. Facility Coment:
Some students may have responded that the first choice for drywell temperature is from the SPDS (Safety Parameter Display System) vice the process computer. This is an acceptable answer because the SPDS drywell temperature is from those two computer points. (Also applicable to requalification question 7.01.b.)
Resolution:
Cross referenced to SRO 7.01 Replacement SR0 7.01 Requalification Coment accepted. SPDS will be added to the answer key for an alternate answer to this question. No change to the point value is required.
f
( 7.09 Facility Coment:
Pressure should also be an acceptable answer to a.1. of this question. This exact scenario has been encountered at QCNPS before and the pressure increase has beet: noted. This is also addressed in the very paragraph of QOP 1000-5 that this question was taken from.
Page 2 of this procedure is attached to show this. (Also applicable to requalification question 7.06.)

Resolution:
Cross referenced SR0 7.09 Replacement SR0 7.06 Requalification Coment is not accepted. Pressure or re-pressurization will not work in the statement made in the question. The procedure states after re-pressurization has occurred to monitor for metal temperature in-crease etc., then stratification is present. Therefore, repressuriza-tion i In part a of this question, high pressure scram should be considered a correct response. This LSSS is listed directly next to the high pressure safety limit and does apply to it. This is shown on page 1.2/2.2-1 of the technical specifications, which is attached.
Concerning the relief valves, the relieve valves are provided to prevent the over pressurization of the vessel. These valves are sized to prevent lifting the safeties when the turbine trips from full power and the bypass valves fail to open. With this in mind, an examinee could easily be misguided by the wording in part b. of this question which asks for a " backup" to the protective actions in
- a. For these reasons, relief valves should be an acceptable answer in a., if the safeties are identified in b. To verify this refer to page 8 of the Main Steam System text and page 1.2/2.2-2 of technical specifications, which are attached. (Also applicable to requalifica-tion question 8.02.)
Resolution:
Cross referenced to SR0 8.02 Replacement SR0 8.02 Requalification Comment is accepted. Any two of the three scrams now listed in the answer key will be accepted for the answer to part a. If high pressure scram is listed in part a, then credit will be given for relief valves in part b.
8.03.a. Facility Comment:
With regard to the station manajement approval, this answer is correct with respect to technical specification 6.2.d. It should be noted, however, that QAP 1100-7 gives guidance in obtaining approval for a temporary procedure change and is more restrictive.
Either answer should be acceptable since no reference was given in the question. A copy of QAP 1110-7 and QAP 1100-T1 are attached.
Also concerning this question, two items are asked for. The approval discussed above is one, however, the review required by On-Site Review and the approval by the Station Manager should be treated as two separate items, with either or both being acceptable.
Again, see attached copy of QAP 1100-7.

Resokution:
The comment is accepted. In Ifeu of the procedure supplied by the facility, that was not originally supplied to the. examiners, the answer key need not be changed because the administrative procedure is more detailed than the answer key and T.S. as originally referenced.
The answer key will be changed, however, in that instead of two possible answers the answer key will be broken down into three possible answers separating On-Site review and Station Superintendent as two possible answers. No change to the point breakdown is needed.
8.04 Facility Comment:
This question does not specify a procedure or circumstance. In this light, several other answers should be acceptable as indicated below with their references. These references are attached.
- 1. Any GSEP condition: reference QAP 300-2 page 11
- 2. Flooding: reference 00A 010-4 page 2

Resolution:
Cross referenced to SRO 8.04 Replacement SRO 8.03 Requalification Comment is accepted. The additional five conditions will be added to the answer key. The five procedures listed will be added to the reference. The point breakdown remains unchanged.
8.06 Facility Cassent:
This question references QAP 300-3 which in turn references Technical Specifications figure 6.1-3, both of which are attached.
While these differ slightly either should be acceptable. (Also applicable to requalification question 8.04)
Resolution:
Cross referenced SR0 8.06 Replacement SRO 8.04 Requalification Comment is not accepted, because the Technical Specifications do not address the position as required and the question ask for "at normal power conditions" not with "there is fuel in both reactors."
12
- a 8.08 Facility Comment:
Initial license candidates are not given specific instruction on 10 CFR 55. At QCNPS, individual licensees do not control these aspects of their licenses. Instead, this is considered an administrative requirement that is enforced by plant management when such a situation arises. A great deal of similar detailed requirements exist on licenses and renewals that are not considered individual licensee responsibilities at QCNPS, instead, the training, administrative and operating department management ensure all requirements are met. This should be taken into consideration when grading this question. (Also applicable to requalification question 8.06)
Resolution:
Cross referenced to SR0 8.08 Replacement SR0 8.06 Requalification Comment is accepted. Since the facility does not hold the candidates responsible for this license condition this question will be deleted from both the replacement and requalification exams and point values adjusted to reflect the deletion.
8.11.a. Facility Comument:
Full credit should be given to an answer that adequately describes the difference between the cards. Detailed color and border schemes should not be required.
Resolution:
Comment is accepted, because paraphrasing is acceptable as long as the candidate describes the card in sufficient detail to answer the question.

ANSWER 5.02 (3.00)
- a. Control rods in the center of the core are exposed to a higher thermal flux than those at the core periphery and, therefore, have a greater worthvEpzfh. (Rod worth would be increased anywhere in the core where a'fadial thermal neutron flux peak existed even if it were an edge rod)[0.5]? ,
- b. As moderator temperature increases, its density decreases resulting in longer thermal diffusion lengths. This allows thermal neutrons to travel further and be absorbed by the rod; [0.5] thus, rod worth increases with an increase in moderator temperature [0.5].
- c. As voids increase, again less moderations takes place. Again, thermal neutrons travel further; however, voids tend to depress thermal flux because of the very poor moderation [0.5]. Thus, as voids increase, rod worth decreases [0.5].

- a. Neutron level would start and continue to increase [0.25] until the point of adding heat is reached [0.25]. As the coolant heats up, negative reactivity is added and power turns [0.25]. Power would stablize at the point of adding heat (0.25].
- b. Period would take a step jump due to the production of prompt neutrons [0.25]. Immediately after this step, the rate of power change decreases to a rate controlled by delayed neutrons until the reactivity is no longer being increased [0.25]. Then a sharp drop would occur as the rate of reactivity addition drops to zero [0.25]. A stable period would continue until negative reactivity is inserted. Stabilize:3 at infinity [0.25].

- a. Control rods in the center of the core are exposed to a higher thermal flux than,those at the core periphery and, therefore, have a greater worth, trod worth would be increased anywhere in the core where a radial thermal neutron flux peak existed even if it were an cdge rod.)
- b. As moderator temperature increases, its density decreases resulting in longer thermal diffusion lengths. This allows thermal neutrons to travel further and be absorbed by the rod; thus, rod worth increases with an increase in moderator temperature.
- c. As voids increase, again less moderations takes place. Again, thermal neutrons travel further; however, voids tend to depress thermal flux because of the very poor moderation. Thus, as voids increase, rod wort decreases.

A. Neutron level would start and continue to increase until the point of adding heat is reached. As the coolant heats up, negative reactivity is added and power turns. Power would stablize at the point of adding heat.
B. Period would take a step jump due to the production of prompt neutrons. Immediately after this step, the rate of power change decreases to a rate controlled by delayed neutrons until the reactivity is no longer being increased. Then a sharp drop would occur as the rate of reactivity addition drops to zero. A stable period would continue until negative reactivity is inserted. Stabilises at infinity.
