REPORT DETAILS
- 1. Examiners:
- Thomas R. Meadows, RV Joe Upton, PNL Leo Defferding, PNL
- Chief Examiner
- 2. Persons Attending the Exit Meeting:
T. Meadows, RV, Chief Examiner D. Mette, SCE, Supervisor of Operator Training M. Hyman, SCE, Unit 2/3 Training Administrator L. Simons, SCE, Unit 2/3 Training Administrator S. Freers, SCE, Training Analyst T. James, SCE, Simulator Administrator R. Maisel, SCE, Compliance K. de Lancey, SCE, Nuclear Af fairs and Emergency Planning C.

- 3. Written Examination and Facility Review:
Written examinations were administered at the facility EOF on March 31, 1987 to one R0 candidate and eleven SR0 candidates. All of the candidates passed these examinations.
The chief examiner met with the facility training staff imediately following the examination to conduct the exam review. Facility generated comments were formalized, endorsed by the facility Vice President and Site Manager, and subsequently forwarded to Region V in accordance with NUREG-1021, ES-201, paragraph H. The NRC resolutions of these comments are attached for both the SRO and R0 examinations, respectively (Attachments 1 and 2).
- 4. Operating Examination:
Operating examinations were conducted during the period of April 1-3, 1987 for the eleven SR0 candidates. All of the candidates passed this portion of the examination. The operating examination portion was waived for the R0 candidate.
The plant specific simulator was found adequate to conduct comprehensive NRC examinations. No general training weaknesses were noted during the operating examinations. However, some operational concerns were identified by the NRC examination team during course of the operating examination.
These concerns were addressed by the Chief Examiner at the examination exit meeting with cognizant facility staff.
2
- 5. Exit Meeting:
On April 3, 1987, the chief examiner met with the licensee representatives listed in paragraph 2. The satisfactory performance of the simulator was discussed.
The Chief Examiner expressed the following concerns:
(a) During the preparation of the written examination and the subsequent examination review, the facility references were found marginal for proper NRC written examination development. Many of the facility generated coments on. specific examination questions were based on technically inaccurate or inconsistent facility supplied reference material. Specific examples were identified to the facility training staff during the course of the examination review, and in the resolution of facility comments (Attachments 1 and 2).
(b) During the simulator portion of the examinations, the NRC examination team identified a problem that the operator candidates had in the use of the facility Emergency Plan Procedures. These procedures do not give adequate event analysis for loss of steam generator feedwater type events until the evolution degenerates to an ultimate loss of heat sink. Eventually, the CRS is directed to the Emergency Plan Procedures via the Emergency Operating Procedures.
(c) During the oral portion of the examination, the NRC examination team had difficulty in accessing controlled radiation areas. The examiners names were not on the general access REP despite assurances that all administrative preparations had been made. At the control point, an examiner noticed that some of the radiation areas survey maps were missing for the areas into which he wanted to take his candidate. Furthermore, the Chief Examiner got contaminated when he entered an area, under escort with his candidate, that was not identified as a contamination area (CCW heat exchanger and pump rooms).
ATTACHMENT 1 SONGS 2/3 FACILITY COMMENTS AND NRC RESOLUTIONS - MARCH 31, 1987 SR0 EXAM QUESTION 5.2(b)(c)
COMMENT:
The flux peak in the lower portion of the core is also a function of fuel depletion. The predominant fuel depletion occurs in the center of the core causing the power to shift to both top and bottom, although the depletion would be slightly more at the bottom of the core than the top, due to normal power distribution being maintained slightly below the centerline. Part b &
c of this question are not separable. The answers for parts b and c could be substituted for each other.
REQUESTED RESOLUTION:
Modify the answer key to accept fuel depletion and lower temperature /high density in the bottom of the core for full credit for-either part b or c.
NRC RESOLUTION: Comment not accepted.
The question breakdown was clear and comprehensive as a unit. This was clearly identified in the structure of the question. The answer key reflects the comprehensiveness of the questinn structure and is consistent with facility supplied references; however, the answer key was adjusted to further clarify the intent of the point assignments upon grading.
QUESTION 5.04b COMMENT:
]
The name of the chemical lithium hydroxide is commonly referred to as
" lithium" by Operations and Chemistry Department personnel.
REQUESTED RESOLUTION:
Modify the answer key to accept either lithium or lithium hydroxide for full '
credit.
NRC RESOLUTION: Comment accepted.
No adjustment to the answer key is necessary. " Lithium" or any responsible fonnula for lithium-hydroxide would be accepted, since it is not the intent of the question to examine the candidate as a plant chemist. We are looking .
for operational knowledge. The answer key is consistent with facility l supplied references.

QUESTION 5.8c COMMENT:
Technical Specifications state the major reason for the DNB Safety limit is to protect the cladding. The 3 safety limits function in conjunction to prevent fission product release.
REQUESTED RESOLUTION:
Modify the answer key to accept " protect the cladding" for full credit.
NRC RESOLUTION: Comment not accepted.
The scope of the answer key clearly addresses the intent of this concern.
The wording of the key is consistent with facility supplied references.
QUESTION 5.12 COMMENT: I 1
(a). Using the Combustion Engineering Steam Table conversion factor for BTU /HR to KW results in a slightly lower calculated value(3405 MW).
(b) SONGS 2/3 are rated at 3410 MW thermal, rather than 3425 MW. Since 3425 MW exceeds the licensed power limit this may have caused undue confusion for some candidates.
REQUESTED RESOLUTION:
Modify the answer key to accept a reasonable numerical range. Allow 3410 MW j as an acceptable value for rated thermal power in the calculation of efficiency.
NRC RESOLUTION: Comment not accepted.
(a) The answer key cannot identify all reasonable ranges for a numeral response, such as required for functional or setpoint type responses.
This action must be performed by the grading examiner. Acceptable ranges depend on the Operational Orientation of the question. Any reasonable range of possible answers will be accepted by the grading examiner. Any awarding of points other than full credit must be l documented by the grading examiner, commensurate with NUREG-1021, '
Examiner Standards.
(b) The intended valve (3425 MWTH) to be used for 100% power was clearly identified by the question.

QUESTION 6.5 COMMENT:
Reference SD-5023-360 also states " Rapid motion of the letdown throttle control valve can cause pressure transients which the letdown backpressure regulating valve controller may not be able to control." ,
REQUESTED RESOLUTION:
Modify the answer key to accept "provides improved backpressure control valve response" or linits pressure transients. Either answer should be acceptable for full credit.
NRC RESOLUTION: Comment not accepted.
Answer key is consistent with facility supplied references. The concern is clearly addressed by the answer key since a pressure transient is certainly the root cause for lifting the relief valve. Subsequently, partial credit would be awarded by the grading examiner. Adjustment of the answer key is not necessary.
QUESTION 6.6 r
COMMENT:
The answer key response is inappropriate. The reference describes " Preferred Manual Mode" as Master Controller in manual and all other stations in automatic.
There is no specific mode selector switch asscciated with the Feedwater Control
- System.
REQUESTED RESOLUTION:
l Modify the answer key to accept the above description of preferred manual as ;
an alternative answer. '
NRC RESOLUTION: Comment accepted. 1 The answer key was adjusted to clarify that an accurate description of this mode of operation would be acceptable.

ATTACHMENT 1 QUESTION 6.9 COMMENT:
The RCS Pressure / Temperature figure supplied with the examination had the word "Heatup" removed. Candidates may have been confused by this since the figure could easily be interpreted as a composite heatup and cooldown curve. While SONGS Technical Specifications do not employ a composite heatup and cooldewn curve, this would not be an unreasonable assumption on the part of the candidates since the labeling of the figure was intentionally modified. The question has responses for both heatup and cooldown curves which would further convince the candidates that the examination figure was a composite diagram.
REQUESTED RESOLUTION:
Modify the answer key to give full credit for the below responses:
Part a (A) accept either 3 or 4 as the correct response.
Part a (B) accept either 5 or 1 as the correct response.
NRC RESOLUTION: Comment not accepted.
The question clearly identifies the requirements of the answer key. The heat up curves (when collectively considered as a group) can be easily identified by any operator candidate with adequate system and operational knowledge of the safety analysis.
QUESTION 6.10(a)(b)
COMMENT:
(a) Common terminology at SONGS to describe switch position associated with the Excore Nuclear Instrumentation is "any switch out of operate or -
off" will cause trouble light.
(b) The question requires memorization beyond that required of an operator.
An operator would be expected to analyze this situation with the appropriate reference material in hand, however, no reference material was provided.
REQUESTED RESOLUTION:
(a) Modify the answer key to accept "any switch out of operate or off."
(b) Delete the question from the exam and redistribute the points as it is beyond what operators are required to memorize.
NRC RESOLUTION: Comment not accepted.
(a) Intent of concern is already incorporated within the answer key for partial credit. The answer key is consistent with the facility supplied reference.
(b) The question is operationally oriented and is consistent with facility references.

COMMENT:
Procedure S023-VII-7.4 states that all areas exceeding .6 mrem /hr (average) will be within restricted areas in addition to .25 mrem /hr being within or
- posted as restricted areas.
I REQUESTED RESOLUTION:
Modify the answer key to accept .6 mr/hr for full credit.
i NRC RESOLUTION: Comment accepted.
The answer key was adjusted in light of information supplied by the facility.
QUESTION 7.4 COMMENT:
5023-13-2 " Shutdown From Outside the Control Room" is an Abnormal Operating Instruction (A01) and therefore consistent with SONGS policy has no immediate actions. The responses required by the answer key are subsequent
, actions.
It is SONGS philosophy that only irmediate actions (which are contained in Emergency Operating Instructions E0Is) require rote memorization.
REQUESTED RESOLUTION:
In-as-much as the question is beyond what SONGS requires operators to
, memorize modify the point distribution to allow full credit for 4 responses rather than six. Additionally, a response to " station an operator at the remote S/D panel" would be an acceptable answer.
NRC RESOLUTION: Comment not accepted.
Question is operationally oriented, especially for an SR0 candidate; however, Step 3.4.1 will be accepted as a possible response in light of ;
facility supplied information. The answer key was adjusted accordingly. '

REOUESTED RESOLUTION:
Modify the answer key to accept " siphon breaker" as an acceptable response for full credit.
NRC RESOLUTION: Comment accepted.
The answer was modified to accept, " siphon breaker on the return header from the cooling system", for full credit. The additional reference supplied by the facility was also included on the answer key.
1 QUESTION 7.10 COMMENT:
Indication in addition to those listed in the answer key are available to give symptoms of an RCP seal failure such as alarms (seal press) and PMS indications such as CB0 flow.
! REQUESTED RESOLUTION:
~l Hodify the answer key to accept additional control room indications other than just the four listed in the answer key such as "RCP seal press HI/LO" j alarm and PMS indication of excessive CB0 Flow / Temp. i NRC Resolution: Comment not accepted.
Question was sufficiently objective such that the four (4) control room indications required by the answer key would not be confused with associated i annunciator and computer generated alarm inputs. Since these associated l indicators are implied by the answer key, no adjustment of the key is '
necessary. Appropriate credit will be awarded by the examiner if it is clear that the candidate is addressing one of the indications required by the answer key.
