Examination Review Meeting At the conclusion of the written examinations, the examiners met with R. G. Jones, J. D. Johnson, A. R. Champion, G. Moody, and E. S. Howard to review the written examinations and answer keys.
The following comments were made by the facility reviewers:
l a.
SRO Exam
{
1.
Question 5.2.a & e (1.25.a & e)
Facility Comment:
"The answer key response required two parts for full credit, but this was not stated in i
question (i.e., why core flow decreases and what caused this action to occur)."
NRC Resolution:
Contrary to the facility's comment, the question did state to " explain the cause(s) of" the designated recorder indications. The two part answers were derived directly from the facility's explanation for the plant response and are required for full credit.
The answer to part "a" has, however, been j
changed to allow full credit for stating that L
2 the recirculation pump would " runback" to minimum speed.
2.
Question 5.4.b (1.24.b)
Facility Comment:
"Concerning the fuel center line temperature with new fuel, your answer key looks for a decrease in fuel center line temperature.
This answer is correct if you consider some exposure time has been received to allow for compaction of the uranium oxide fuel.
Our MAPLHGR limits are adjusted to depress the new fuel Kw/ft limits to allow this compaction.
During this compaction the Helium gap increases, which decreases the heat transfer and will increase fuel center line tempera-ture.
After the compaction and the fuel cracks propogate (sic) and ratchet open, the helium gap decreases and increases heat transfer rate which will decrease the fuel center line temperature.
Reference page 9 Linear Heat Gen.
Rate &
Bases Lesson Plan thermo book.
D.5.a. new fuel exposed to operating temperature, densification occurs.
Reference transparency #2 Thermo-APLHGR Lesson plan tables of fuel types indicates depressee (sic) Kw/ft fuel limits from 0-200 mwd /t on exposures.
Reference page 171-172a-U-1 Tech Spec with fuel types from 0-200 mwd / ton exposure the heat transfer in KW/ft is depressed, due to poor heat transfer rates due to densification.
The question just addressed new fuel, it did not specify an exposure so based upon these references initially the fuel center line temperature of new fuel will increase due to poor heat transfer. After the cracks propo-gate (sic) and ratchet open fuel center line temperature will decrease. According to Tech Spec table this should have occurred by 200 mwd / ton exposure.
If a candidate responds with increase or - decrease, it should be accepted since no fuel exposure was specified."
l 3
NRC Resolution:
The reference quoted in the answer key states that the helium gap is essentially closed shortly after initial operation.
It was not considered necessary, therefore, to specify an exposure level in the question.
Based upon the references cited in the facility s comment, it is agreed that the most correct response of fuel centerline temperature to initial exposure is to increase due to fuel densification.
Any helium gap closure, and consequent fuel centerline temperature decrease, will occur after the fuel densifi-cation. The answer key has been changed to accept increase, rather that decrease, as the correct response.
3.
Question 5.4.d (1.24.d)
Facility Comment:
"Concerning question 1.24.d 'The effect on fuel center line temperature of operating with one MSIV closed.'
The question was stated ' operating with' this would indicate that the reactor had stabilized and survived the closure.
Initially the reactor pressure would increase and fuel center line temperature would increase during this transient. But as the EHC stabilizes the RpV pressure the center line temperature would effectively be the same while ' operating' with the one MSIV closed.
The candidates may respond with an increase, same as your answer key, if considering the fuel center line during the transient. Others will respond with ' remain the same' after the transient has stabilized."
NRC Resolution:
This comment is invalid in that it was not addressed during the allotted examination review period and should, therefore, have been made in writing to the Regional Branch Chief in accordance with Generic Letter 84-05.
It is also technically invalid in that it is not substantiated by the facility's reference material. The TVA BWR Simulator Instructor's Manual, malfunction #5, " Main Steam Line Isolation Valve (MSIV) Closure,"
indicates that the steady-state reactor pressure after an MSIV closure would be higher. Since a BWR operates under saturated conditions, this m
i 4
would result in a highar coolant temperature and, therefore, a higher fuel centerline temperature. No change to the answer key is warranted.
4.
Question 5.11 (1.19)
Facility Comment:
"This question's answers were all long and the time requirement to determine the most correct answer was too much for the assigned point value. Also the length of the answers make it too difficult to analyze each part."
NRC Resolution:
A candidate with a knowledge and understanding of the reactor heat balance equation should hav,e no difficulty in determining the one and only correct answer without having to perform l
a cifficult analysis of each part.
The i
question and answer key require no change.
l l
S.
Question 6.11 (3.13)
Facility Comment:
" Answer
'B' also could be correct if you consider that you are moving the last rod in a group.
This rod could then be moved two notches without violating any restriction."
l NRC Resolution:
The "b" distractor would be a correct answer to the question if the candidate assumed that the last rod in a group was being moved. The facility's reference material should be updated to reflect this anomaly. The answer I
key has been changed to include "b" as a correct response.
l 6.
Question 6.14 (2.4) i Facility Comment:
"Concerning question about what will trip a l
Diesel Generator during accident condition.
l Per 01 82 (Jan. 25, 1983) for UI & U2, i
differential and field failure both will trip l
D/G. The D/G lesson plan only list differen-tial, which is the correct answer. The OI 82 for U1 & 2 has been changed, but not in the material sent to NRC.
l Recommend that accept either answer as being correct."
I 5
(
i l
(
NRC Resolution:
This comment is invalid in that it was not addressed during the allotted examination review period (See resolution of Question 5.4.d).
The question and answer key accurately reflect the current equipment configuration and require no change.
7.
Question 6.17(2.13)
Facility Comment:
Per OI 84: Do not make-up nitrogen to the primary containment if venting is in progress, i
This would make answer 'c' incorrect."
NRC Resolution:
The question was intended to test the candi-dat.es' knowledge of the design of the Contain-ment Atmosphere Dilution System rather than its operating limitations.
The facility's I
comment is, however, valid and the question has been deleted from the examination.
8.
Question 6.26 Facility Comment:
"Concerning question 6.26 on the refueling interlocks with the moda switch in startup.
The copy of lesson plari 53 Figure 4 had a line inadvertently left off. Therefore the candi-dates response may be in more detail than the j
NRC answer key.

6 NRC Resolution:
The Browns Ferry Nuclear Plant FSAR Figure 7.6.1 substantiates the facility's comment.
The answer key has been changed to include the additional information.
9.
Question 7.2 Facility Comment:
"A possible correct answer is 'a' per 0123 pg. 6, IV a.3..
Terminology of securing S. D.
cooling may be interpreted 'as removing that loop from service.'"
NRC Resolution:
The terminology, " secure RHR shutdown cooling," is quite explicit and also quite different from rerouting the RHR water through another heat exchanger as directed by OI-23.
Distractor "a" is not an acceptable answer to the question.
10.
Questien 7.4 (4.3)
Facility Comment:
"There doesn't seem to be any completely correct answer for this question if you considered that the RFPT was reset as given in direction to the class during the exam.
With the RFPT reset:
the AOP would be running, the suction valve open, the di:: charge valve closed, the minimum flow valve open, the blue lignt out, and in single element control."
NRC Resolution:
The candidates had been told to make an assumption based upon an incorrect interpreta-tion of 01-3, "Feedwater System," as verified on the Browns Ferry Simulator.
Since the stated assumption made none of the possible answers correct, this question has been M
deleted from the examination.
11.. Question 7.5 (4.4)
Facility Comment:
" Question concerning rubbing noises on Main Turbine at 100 rpm The correct answer (as shown on NRC answer key) contains statements from various sections of OI 47.
The correct answer contained an action statement requiring breaking vacuum.
This action statement was taken from Section III G.3.b which deals with actions to
t 7
be taken during emergency shutdown. The note is contained in the section which gives action to be taken at 1200-900 rpm range. Breaking vacuum at 100 rpm would have negligible effect on reducing the speed and could cause adverse effects on the unit due to pressure transient when the bypass valves go closed at 7"
vacuum."
NRC Resolution:
An immediate turbine
- shutdown, per section III.D.I.e of 01-47, to protect plant equipment is considered to be an emergency shutdown (i.e. not normal) and thereby invokes
~ ~
the requirements of section III.G of that procedure. Although breaking condenser vacuum may not always be desirable, it is not incorrect. All the other possible answers to this question contain obviously incorrect actions per the OI; no change to the answer key is warranted.
- 12. Question 7.12 Facility Co=ent:
"See co=ents on R0 Section 4.11"
.NRC Resolution:
No co= ment on question 4.11 could be found in,
Facility Exam Co=ents.
The question and answer key were verified in accordance with the stated reference.
No change is considered necessary.
- 13. Question 7.22 (4.23)
Facility Comment:
" Question is requiring memorization of information within an appendix to a procedure.
The only immediate action per the procedure is to dispatch an operator to the backup control center."-
NRC Resolution:
The situation described in the question may be indicative of a simultaneous loss of' HPCI, ADS, and normal SRV protection.
The body of GOI-100-11 CAUTIONS the operator to perform the actions of the appendix concurrent with those of the procedure when such a situation occurs.
' Candidates able to conceptually describe the methods and objectives of the I
remedial / follow-up actions after dispatching an operator to the Backup Control' Center will receive the majority of the credit for the question.

- 17. Question 8.25 Facility Comment:
"This question requires memorization of an LCO. The Tech Specs are readily available in the control room for the SR0 to utilize in determining the LCO."
NRC Resolution:
The question is consistent with NUREG-1021,
" Operator Licensing Examiner Standards," in that it addresses an operating limitation as specified in the facility's Technical Specift-cations (Ref. ES-402). License candidates are expected to have a thorough knowledge of, and the ability to apply, significant Limiting Conditions for Operation (LCOs). No change to the question or answer key is warranted.
b.
R0 Exam Several facility comments apply to questions which appeared on both the R0 and SRO examinations. Those questions were addressed in section 3.a of this enclosure and will not be duplicated here.
1.
Question 3.14 Facility Comment:
"When 70% undervoltage is achieved on U-1 panel 9-9 the panel will automatically transfer to the U-2 unit preferred panel 11 breaker 1172. This transfer is for panel 9-9 only and is accomplished by an ASCO throw over switch if the. alternate supply has voltage.
Your answer was misleading in the fact that it addressed the U-1 unit preferred bus, which is in effect panel 11 in the battery board room, fed directly from the 1001, 1002 and 1003 breakers. Upon the loss of an MG set this panel will de-energize, but panel 9-9.in the control room will transfer to its alternate supply, U-2 breaker 1172, if potential is available. The result will be the U-1 unit preferred bus de-energized, which is panel 11 in battery board-room, and panel 9-9 energized from an alternate source.
ASCO - throws to alternate at 70% voltage with return to normal at 90% when normal potential is regained page 98 OI 57 U.R.2.b. addresses panel 9-9"
10 NRC Resolution:
The facility's comment is. substantiated by the additional reference material.
The question inferred that.the entire UPS bus transferred to an alternate supply when only the 9-9 panel does, in fact, transfer.
The question has been deleted from the examination.
2.
Question 3.28 Facility Comment:
"Concerning the question on the RWA latching into a group resulting in insert and withdraw errors.
The answer to part 'B' (after the rod in Group 1 has been withdrawn) would be depended (sic) upo,n whether the RWM was re-initialized or a red in Group 4 were selected or if all that was done was select a rod in Group 1 and withdraw it to 48.
Condition one:
Select rod in Group 1 and withdraw Results:
Group 3 remains latched group Only insert error is rod in group 2 Group 4 rod remains withdraw Condition two:
Select rod in group 1 and withdraw Select rod in group 4 Results:
Group 4 becomes latched group have two insert error (rod in Group 2 and 3)
No withdraw errors Condition three:
Select. rod in group 1 and withdraw re-initialize the RWM Results:
Same as condition two"
11 l
NRC Resolution:
The facility's comment is valid in that the candidates had to make an assumption to arrive at the answer specified in the answer key. If the candidate states his assumption and answers the question correctly based upon that assumption, then he will receive full credit for the question. If no assumption is stated, then the question will be graded per the answer key.
3.
Question 4.17 Facility Comment:
" Question does not call for response to first part of answer 'To produce sufficient pump head to create down thrust on the pump'"
NRC Resolution:
The brief explanation stated in the answer key was derived directly from 0I-27, " Condenser Circulating Water System." Both parts of the answer are required to fully explain the operating precaution. No change to the answer key is warranted.
4.
Exit Meeting At the conclusion of the site. visit, the examiners met with representatives of the plant and Nuclear Training Branch (NTB) staffs to discuss the results of the examination.
Those individuals who clearly passed the oral and simulator examinations were identified.
There were no generic weaknesses (greater than 75 percent of candidates giving incorrect answers to one examination topic) noted during the oral examinations.
Mr. R. J. Johnson, Chief, NTB, requested that copies of the written examinations and answer keys be left with the training staff. In accordance with established NRC policy, this request was denied. The meeting attendees were reminded, however, that copies of the master examinations and answer keys would be forwarded with the examination report.
The cooperation given to the examiners and the effort to ensure an atmo-sphere in the control room conducive to oral examinations was also noted and appreciated.

.f 1.0 DEFINITIONS The succeeding frequently used terms are explicitly defined so that a uniform interpretation of the specifications any be achieved.
A.
Saf ety Limit - The safety limits are limits below which the reason-able maintenance of the cladding and primary systems are sasured.
Exceeding such a limit requires unit shutdown and review by the Atomic Energy Commission before resumption of unit operation.
Operation beyond such a limit may not in itself result in serious consequences but it indicates an operational deficiency subject to regulatory review.
B.
Limitina Safety System Settina (LSSS) - The limiting safety system setting are settings on instrumentation which initiate the automatic protective action at a level such that the safety limits will not be exceeded. The region between the safety limit. sad these settings represent margin with normal operation lying below these settings. The margin has been established so that with proper operation of the instrumentation the safety limits will never be exceeded.
C.
T4=4 tina Conditions for Operation (LCO) - The limiting conditions for operation specify the minimum acceptable levels of system performance necessary to assure safe startup sad operation of the facility. When these conditions are met, the plant can be operated safely and abnormal situations can be safely controlled.
g 1.
In the event a Limiting Condition for Operation and/or associated requirements cannot be satisifed because of circumstances in excess of those addressed in the specif1-cation, the unit shall be placed in at least Hot Standby within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in Cold Shutdown within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> unless corrective measures are completed that permit operation under the permissible discovery or until the reactor is placed in an operational condition in which the specification is not applicable. Exceptions to these requirements shall be stated in the individual specification's. This provides actions to be taken for j
circumstancas not directly provided for in the specifications and where occurrence would violate the intent of the 1
specification. For example, if a specification calls for two systems (or subsystems) to be operable and provides l
for explicit requirements if one system (or subsystem) is i
inoperable, then if both systems (or subsystems) are inoperable the unit is to be in at least Hot Standby in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in Cold Shutdown within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br /> if the inoperable condition is not corrected.

When a system, subsystem, train, component or device As determined to be inoperable solely because its onsite power soutes is inoperable, or solelybecause its offsite power source is inoperable, it any be considered operable for the purpose of satsadyeng the requirements of its applicable Limiting condition For Operation, provided:
(1) its corresponding offsite or diesel power source is operable; and (2) all of its redundant systea(s), subsystem (s), train (s),

This is not applicable if the unit is already in Cold Shutdown or Refueling. This provision describes what additional conditions ~ mast be satisfied to permit operation to continue consistent with the specifications for power sources, when an offsite or onsite power source is not operable. It specifically prohibits operation when one division is inoperable because its offsite or diesel power source is inoperable and a systaa, subsystem, train, component or device in another division is inoperable for another reason. This provision permits the requirements associated with individual systems, subsystems, trains, components or devices to be consistent with the requirements of the associated electrical power source. It allows operation
/
to be governed by the time limit of the requirements associated with the Limiting Condition For Operation for the offsite or
' diesel power source, not the individual requirements for each system, subsystem, train, component or device that is determined to be inoptrable solely because of the inoperability of its offsite or diesel power source.

- the knowledge level expected of the candidates. However, the method used to ensure that the correct answer wasn't obvious created the following problem areas:
1., Required indepth reading of answer which proved to be too time consuming for the SRO candidates. One word or letter designation made the answer right or wrong. 2. In more than one incident the question required detailed memorization of :satorial that would normally be readily available to the operator, and was not stated in the procedure as an immediate operator action. 3. In many cases, questions and/or answers did not contain sufficient information and required the candidates to make undocumented assumptions that affected his determination of a valid answer.

Qu:stian 1.19 f l This question's answers were all long and the time requirement to determine the most correct answer was too much for the assigned point value. Also the length of the answers make it too difficult to analyze i each part. l 1 Question 1.24/5.4 t Concerning the fuel center line temperature with new fuel, your answer key looks for a decrease in fuel center line temperature. This answer is ~ i correct if you consider some exposure time has been received to allow for compaction of the uranium oxide fuel. Our MAPLHGR limits are adjusted to depress the new fuel Kw/ft limits to allow this compaction. During this compaction the Helium gap increases, which decreases the heat transfer and 1 will increase fuel center line. temperature. After the compaction and the fuel cracks propogate and ratchet open, the helica gap decreases and increases heat transfer rate which will decrease the fuel center line temperature. Reference page 9 Linear Heat Gen. Rate & Bases Lesson Plan thermo book. D.S.a. new fuel exposed to operating temperature, densification occurs. Reference transparency #2 Thermo-APLHGR Lesson plan tables of fuel types indicates depressee Kw/ft fuel limits from 0-200 mwd /t on exposures. j Reference page 171-172a-U-1 Tech Spec with fuel types from 0-200 mwd / ton l exposure the heat transfer in Kw/ft is depressed, due to poor heat transfer rates due to densification. The question just addressed new l fuel, it did not specify an exposure so based upon these references initially the fuel center line temperature of new fuel will increase due to poor heat transfer. After the cracks propogate and ratchet open fuel center line temperature will decrease..According to Tech Spec table this should have occurred by 200 NWd/ ton exposure. If a candidate responds with increase or decrease, it should be accepted'since no fuel exposure was specified. i 4 Concerning question 1.24.d "The effect on fuel center line temperature of operating with one'NSIV closed." The question was stated " operating with" this would indicate that the reactor had stabilized and survived the closure. Initially the reactor pressure would increase and fuel center line temperature would~ increase during this' transient. But as the EHC stabilizes the RPV pressure the center line temperature would effectively be the same while " operating" with the one NSIV closed. a yv tw y 5' erp*i e m e-T+- 3-m? + - * * - - f W '5%'=" M
Qu :tica 1.24/5.4 (ccatinued) The candidates may respond with an increase, same as your answer key, if considering the fuel center line during the transient. Others will respond with " remain the same" after the transient has stabilized. Question 1.25 (a) and (e) The answer key response required two parts for full credit, but this was not stated in question (i.e., why core flow decreases and what caused this action to occur). Question 2.13/6.17 Per OI 84: Do not make-up nitrogen to the primary containment if venting is in progress. This would make answer 'c' incorrect ~
Qu:stien 3.13/6.11 Answer 'B' also could be correct if you consider that you are moving the last' rod in a group. This rod could then be moved two notches without violating any restriction. Question 3.14 When 70% undervoltage is achieved on U-1 panel 9-9 the panel will automatically transfer to the U-2 unit preferred panel 11 breaker 1172. This transfer is for panel 9-9 only and is accomplished by an ASCO throw over switch if the alternate supply has voltage. Your answer was misleading in the fact that it addressed the U-1 unit preferred bus, which is in effect panel 11 in the battery board room, fed directly from the 1001, 1002 and 1003 breakers. Upon the loss of an MG set this panel will de-energize, but panel 9-9 in the control room will transfer to its alternate supply, U-2 breaker.1172, if potential is available. The result will be the U-1 unit preferred bus de-energized, which is panel 11 in battery board room, and panel 9-9 energized from an alternate source.

r Qu:stica 4.3/7.4 There doesn't seem to be any completely correct answer for this question if you considered that the RFPT was reset as given in direction to the class during the exam. With the RFPT reset: the AOP would be running, the suction valve open, the discharge valve closed, the minimum flow valve open, the blue light out, and in single element control Section 4 & 7 Question concerning rubbing noises on Main Turbine at 100 rpm The correct answee (as shown on NRC answer key) contains. statements from various' sections of OI 47. The correct answer contained an action statement requiring breaking vacuum. This action statement was taken from Section III G.3.b which deals with actions to be taken during emergency shutdown. The note is contained in the section which gives action to be taken at 1200-900 rpm range. Breaking vacuum at 100 rpes would have 4 j negligible effect on reducing the speed and could cause adverse effects on the unit due to pressure' transient'when the bypass valves go closed at 7" vacuum. 1 1 l 1 ,.r, ,,.-w.-~-< v y p.,-, -,.y,-<-
