- 2. Ex_ amination Review Meeting At the conclusion of the requalification written examination, the questions and answers were given to the facility training staff for review and comment.
Subsequent to this on August 1, -1986, the licensee provided their consnents to the Reactor Operator and Senior Reactor Operator requalification written examinations. The facility consents and the examiner's resolutions to each are on the enclosed attachment.
- 3. Simulator Examina_ti_on_s_
Simulator examinations were initially administered to four Reactor Operators (RO) and eight Senior Reactor Operators (SRO) on July 30-31, 1986. The-initial results of these examinations indicated that the four RO's had passed and that five of the eight SR0's had failed. Further assessment of the SR0 examinations revealed that a number of irregularities existed (eg inconsis-tencies between written and simulator examination results; lack of agreement between NRC personnel on the grading the simulator examination results; and a two-week delay by the examiners in reaching a conclusion regarding failure of the simulator examination after informing the chief examiner, superiors and the licensee that there were no significant problems identified). Based on this assessment it was concluded that the results were indeterminate and the decision was made to administer a second set of simulator examinations to the five SR0,s. On August 19, 1986, aConfirmatoryActionLetter(CAL)
(RIII-CAL No.86-005) detailing the above and stating the NRC's understanding that the five SR0's had been removed from any licensed duties pending completion of the second set of examinations was issued.
The second set of simulator examinations was administered on August 27-28, 1986. In addition to four of the five suspect SR0's, simulator examinations were administered to one additional R0 and four additional SR0's who had not been previously examined. One of the suspect SR0's was not available to take the reexamination and will continue to be removed from licensed duties.
All eight of the SR0's and the one R0 who participated in the simulator reexamination passed. Based on their successful completion of the simulator re-examination the four suspect SR0's were allowed to return to licensed 3
r activities on August 29, 1986. The above, as well as the successful completion of all actions and conmitments in the August 19, 1986, CAL was documented in a September 10, 1986, letter (J. G. Keppler to B. R. Sylvia) to the licensee.
'4. Exit Meeting On August 1, 1986, an exit meeting was held. The following personnel were present at this meeting:
Licensee: B. R. Sylvia, Group Vice President C. E. Aldepson, Advisor to the Vice President, Nuclear Operations F. E. Agosti. Vice President, Nuclear Operations J. T. Coleman, Supervisor, Nuclear Operations Training G. R. Overbeck, Superintendent of Operations J. E. Conen, Licensing Engineer S. V. Heard, Operations Coordinator T.E.Lang, Contractor (FRGCorp.)
NRC: R. D. Lanksbury, Chief Examiner, RIII L. R. Miller, Examiner, NRC Headquarters A. J. Mendiola, Examiner, NRC Headquarters The following general weakness's with regard to the the SR0's were presented:
- a. Some SR0's exhibited difficulty with procedural compliance.
- b. Some SR0's exhibited conmunication difficulties (use of terms such as "the level is high" without elaborating how high the level was or how close to a setpoint, etc.).
On August 29, 1986, an exit meeting for the simulator reexaminations was held. The following personnel were present at this meeting:
Licensee: B. R. Sylvia, Group Vice President R. S. Lenart, Plant Manager G. R. Overbeck, Superintendent of Operat.ons L. C. Lessor, Advisor to Plant Manager S. J. Latone, Director Nuclear Training J. T. Coleman, Supervisor, Nuclear Operations Training G. Reece, Operations Training Coordinator G. E. Abramson, Asst. Operations Engineer, Simulator J. E. Conen, Licensing Engineer NRC: E. G.

Munro, Acting Operator Licensing Section Chief, RII L. Wiens, Examiner, NRC Headquarters D. N. Graves, Examiner, RIII R. DeFayette, Project Engineer 4
m The following general weaknesses with regard to the SR0's were presented:
- a. Procedure implementation by shift supervisors,
- b. Connunications by shift supervisors.
In addition, the satisfactory results of all nine SR0's was made known and the licensee was informed that the CAL hold on the four suspect SR0's, preventing them from participating in licensed activities, was terminated.

ATTACHMENT FACILITY EXAMINATION COMMENTS AND EXAMINER RESOLUTION FOR FERMI II EXAMINATION ADMINISTERED JULY 29, 1986
- 1. Question 1.01 Facility Co_nment:
Due to the broad nature of the question, there are numerous answers to this question. i.e. burnable poison load, rod speed, fuel enrichment etc.
Resolution:
Commented accepted - Answers such as those provided above were accepted.
- 2. Question 1.06b. and d.
Facility Coment:_
- b. Depending on local / average flux value and location of the control rods in group 5 vs group 7, other answers may be acceptable with justification,
- d. Typically, the operators are prohibited from changing the size of the control rods.
Resolution:
- b. Commented accepted - other answers were considered with adequate justification.
- d. Connent understood, however question was a theory question and ment to test the operators kncwledge of rod worth.
- 3. Question 2.02 Facility Comment:
We do not require setpoint memorization of unimportant facts. The purpose of the valves is important, not a value which the operator can neither nionitor nor control.
Resolution:
Coment accepted - Question and answer key have been changed to not require the setpoint of the equalizing valves.
- 4. Question 2.03
[ac,11i_ty_ Comment:
There is no air heater or air flow in standby. A comparable answer would be to say that we built a building around the diesels.
Resolution:
Coment accepted - The answer key answer is the flow path as stated in the reference material provided. The answer key does not state that there is air flow. However, for clarity the portion of the answer about the air coolant system is not required for full credit and the answer key has been changed to reflect this. Point values were also redistributed.
- 5. Question 2.04.6 Facility Coment:
We normally discuss the negative pressure as leading to failure of the drywell, not giving excess loading to the floor.
Resolution:
Coment accepted - This answer is considered equavalent to that in the answer key.
- 6. Question 2.05.a Facil_ity Comment:
An acceptable answer should be "to allow more time between the first and second lift to allow the tailpipe to drain."
Resolution:
Comment accepted - The answer key has been changed to include the above i answer.
- 7. Question 2.06 Facility Comment:
Again, we do not require that operators memorize the less significant setpoints. Also, a review of tech specs shows that:
- 1. A HPCI isolation occurs at an exhaust diaphram pressure of 20 psi.
- 2. There is an interlock between the Exhaust valve and the ability of HPCI to initiate. See HPCI Student handout.
_Resolu tion:
Comment accepted - The answer key was changed to include the above two answers and to eliminate the requirement to know the rupture disk setpoint.
- 8. Question 3.0.2.a. b, and c Facility Comment:
- a. The RFP's will decrease in speed. This is the initial response, all else subsequent or attendant response.
- b. Decrease to minimum speed, all else is subsequent.
2
- c. Depending on the assumption of the examinee, either an increase or decrease in speed is possible. If the pumps are assumed to be operating above 78% speed, they will of course decrease in speed.
If, on the other hand the pumps are running at less than 78% speed, the loss of the suction flow from the heater drains will result in an increase in speed. The limit of 78% will still apply.
Resolution:
- a. and b. Comment accepted - Answer key changed, but answer still requires a proper explanation of the control system response.
- c. Conment understood - Will accept either answer, but answer still requires a proper explanation of the control system response.
- 9. Question 5.03 Facility Connent:
This question could be answered correctly as either A or B. B is correct since if I select A-3/4 with A-1/2 rods at some intermediate position the selected groups of rods will backlight. Also these indications are clearly specified in our Procedure 23.623. We do not require that the operator memorize all of the possible combinations of things that can be done to get a particular light configuration. We concentrate on recognizing the proper lighting display for the proper operation.
Resolution:
Conment rejected - Question states that a normal startup is in progress.
In this case, all A-12 rods must be withdrawn to establish the
" checkerboard pattern" before any A-34 rods can be moved.
- 10. Question 3.04 a and b Facility Conment
- a. We feel that the error limiting network is of limited importance in this situation. We feel that 0.75 points should be assigned to the 45% limit and 0.25 points assigned to the Error Limiting network.
- b. The Reactor recirc pump will trip if the valve is not greater than 95% open after the start sequence is complete. See the same student handout used as reference in the question.
Resolution:
a and b comments accepted - The answer key has been changed to reflect the above.
- 11. Question 3.06.a facility _Connent:
This question is sonewhat misleading. You are asking for actions where non exist.
3
1 Resolution:
Coment accepted - Part "a" has been deleted.
- 12. Question 3.08 Facility Coment:
We have trained the operators to exercise caution anytime two MSIV's will be closed by emphasizing that this is a situation which may cause a 1/2 scram. We have not emphasized the possible combinations which will actually cause the 1/2 scram.
Resolution:
Coment rejectea - Question is intended to determine if operator knows RPS logic for closure of the MSIV's.
- 13. Question 4.06
)
facijity Coment:
This question is SR0 level. The R0's are not typically involved beyond the preparation of the PCR.
Resolution:
Comment rejected - Answer key gives the steps leading up to, and including writing of, a PCR. Procedure 12.000.07 states that it is the authors responsibility to get the required interim signatures. Therefore you have to know who can sign the PCR.
- 14. Question 4.07.c Facili_tX Coment:
Either the SRM's or IRM's may be used.
Resolution:
4 Connent accepted - The answer key has been changed to reflect the comment.
- 15. Question 5.02 facili_ty Coment:
As worded, this question may be interpreted as True/ False.
- a. T c. F
- b. F d. F Concent understood, will accept any correct answer method.
1
, 16. Question 5.04 4
Facility Consnent:
This reference is unknown to us. Please provide us with a copy. Also,
, the B part of the question should be answered as DECREASE.
. Resolution:
The correct reference is the " Decrease in core coolant flow. events study
- guide," NT/R334/6.0 from the 0C & P course. Comment for Part B accepted 7 and answer key changed.
i
- 17. Question 6.01 Facility Coninent:
I This would be true 'if we have a loss of power or as a general statement.
Normally, the battery chargers are operating on a float above the battery
. voltage so the logic could be considered to be powered from the chargers.
Either true or false should be acceptable in this case.
NRC Resolution:
f
! Accepted, answer key changed.
2
- 18. Question 6.01 Facility Comen_t: ,
. According to drawing 2095-7, the signal is sent to the LOGIC but does not :
actuate it. Again, either true or false appears to be correct.
, NRC Resolution:
i i Comment rejected. On Page 14 of PIS E21, it states that two Core Spray pump 3 l running signals are required to send a permissive signal to the ADS logic.
i i 19. Question 6.03.b i I Facility Comment:
r l The second part of the answer is inappropriate. The question does not ask why the time delay is set at 117 seconds, it asks why there is a time delay.
- NRC Resolution:
{ Coment accepted. Answer changed.
l 20. Question 6.03.c l Facility Comeg:
! Should be turned off pumps.

NRC Resolution:
Comment accepted. Any action which will prevent the low pressure pumps from starting will be accepted.
- 21. Question 6.04.a Facility Comment: -
The RFPs will decrease in speed. This is the initial response, all else is subsequent or attendant response.
NRC Resolution:
Comment accepted. Answer Key changed, but answer still requires a proper explanation of the control system response.
- 22. Question 6.04.b Facility Comment:
Decrease to minimum speed, all else is subsequent.
NRC Response:
Comment accepted. Answer key changed, but answer still requires a proper explanation of the control system response.
- 23. Question 6.04.c Facility Comment:
Depending on the assumption of the examinee, either an increase or decrease in speed is possible. If the pumps are assumed to be operating above 78% speed, they will of course decrease in speed. If, on the other hand the pumps are running at less that 78% speed, the loss of the suction flow from the heater drains will result in an increase in speed.
The limit of 78% will still apply.
NRC Resolution:
Comment understood. Will accept rather answer, but answer still requires a proper explanation of the control system response.
- 24. Question 6.06 b Facility _ Comment:
Which local panel? The diesel can be tripped from the local panel adjacent to the diesel.
6
NRC Resolution:
Connent rejected. Understanding that there are two diesel local panels,
- during orals when the operators were questioned about the diesel local control panel, they led the examiners to the control panel in the EDG switchgear room. From this panel the EDG cannot be tripped when it is running in the emergency mode.
- 25. Question 6.06.c Facility Connent:-
"EACH" is misleading. It implies TEN (10) starts which is false.
NRC Resolution:
This part of the question is deleted. The student handout is specific in wording starts page(that it student B of implies handout).
that the air75%
receivers haveanswered of the SR0s enoughthis air for 10 question TRUE and some of them stated that the air receivers had enough air for 10 starts during the plant walk-throughs.
- 26. Question 6.06.d Facility Conment:
Should be false. The burn rate for a loaded diesel is 180 to 200 GPH.
The capacity is 210 gallons if at minimum.
NRC Resolution:
Comment rejected. Page 11 of the student handout specific 611y states two hours.
- 27. Question 6.07.a Facility Connent:
Should also accept ERR 0NE0US rod withdrawal in areas of high power density during high power operation. This is stated in the student handout as part of the system.
NRC Resolution:
Connent accepted. Answer changed to reflect the student handout explanation of the purpose of the RBM.
- 28. Question 6.07.c Facility _Connent:
Nulling sequence also causes a bypass of the RBM.
NRC_ Resolution:
Convent accepted. Answer key chan ed.
- 29. Question 6.08 Facility Coment:
This question could be answered correctly as either A or B. B is correct since if I select A-3/4 with A-1/2 rods at some intermediate position the selected groups of rods will backlight. Also these indications are clearly specified in procedure 23.623. We do not require the operator memorized all the possible combinations of things that can be done to bet a particular light configuration. We concentrate on recognizing the proper lighting display for the proper operation.

- c. Remains constant [.25). Flow is controlled by the RCIC flow controller which will attempt to maintain a constant output flow regardless of reactor pressure [0.5).
- b. Decreases [0.25). The flow controller functions to maintain a constant flow, thus pump discharge pressure is decreased along with ORthe Since the decreasing reactor pressure to maintain a constant flow. as reactor flow controller maintains a constant flow to the reacter, preasure decreases, the pump discharge head must decrease to maintain a constant flow (constant NPSH) [0.5),
- c. Decreases [0.25). Since pump discharge head is decreasing to maintain a constant flow, turbine RPM must also decrease [0.5).
