4OA5 Operator Licensing Examinations
a. Inspection Scope
The NRC evaluated the submitted operating test by combining the scenario events and JPMs in order to determine the percentage of submitted test items that required replacement or significant modification. The NRC also evaluated the submitted written examination questions (RO and SRO questions considered separately) in order to determine the percentage of submitted questions that required replacement or significant modification, or that clearly did not conform with the intent of the approved knowledge and ability (K/A) statement. Any questions that were deleted during the grading process, or for which the answer key had to be changed, were also included in the count of unacceptable questions. The percentage of submitted test items that were unacceptable was compared to the acceptance criteria of NUREG-1021, Operator Licensing Standards for Power Reactors.
The NRC reviewed the licensees examination security measures while preparing and administering the examinations in order to ensure compliance with 10 CFR §55.49, Integrity of examinations and tests.
The NRC administered the operating tests during the period March 7-11, 2016. The NRC examiners evaluated two Reactor Operator (RO) and five Senior Reactor Operator (SRO)applicants using the guidelines contained in NUREG-1021. Members of the Sequoyah Nuclear Plant training staff administered the written examination on March 23, 2016.
Evaluations of applicants and reviews of associated documentation were performed to determine if the applicants, who applied for licenses to operate the Sequoyah Nuclear Plant, met the requirements specified in 10 CFR Part 55, Operators Licenses.
The NRC evaluated the performance or fidelity of the simulation facility during the preparation and conduct of the operating tests.
b. Findings
No findings were identified.
Members of the Sequoyah Nuclear Plant training staff developed both the operating test and the written examination. All examination material was developed in accordance with the guidelines contained in Revision 10 of NUREG-1021. The NRC examination team reviewed the proposed examination. Examination changes agreed upon between the NRC and the licensee were made per NUREG-1021 and incorporated into the final version of the examination materials.

During performance of JPM C, an applicant failed to open FCV-63-7, RHR Supply to SI pump
suction. In the original version of the JPM, at JPM step 19, the applicants were expected to
open BOTH FCV-63-6 AND FCV-63-7 per step 11 of the procedure as noted below. This step
was marked as CRITICAL due to the belief that both valves were required to provide suction
flow from the RHR pumps to the suction of the SI pumps. After a review of ES-1.3 TRANSFER
TO RHR CONTAINMENT SUMP and drawing 47W811 sheet 1, it was confirmed that both FCV-
63-6 and FCV-63-7 RHR Supply to SI pumps suction are in parallel. Therefore, opening either
valve provides flow from the RHR pumps to the SI pumps suction. Sequoyah requests the
wording for the critical step on JPM step 19 be changed to open EITHER FCV-63-6 OR FCV-
63-7.
From ES-1.3 TRANSFER TO RHR CONTAINMENT SUMP
NRC Resolution:
The licensees recommendation to modify the wording of the critical step for JPM step 19 to open
EITHER FCV-63-6 OR FCV-63-7 is accepted. A review of drawing 47W811 sheet 1 verified that
FCV-63-7 and FCV-63-6 are in parallel:
Therefore, opening only one of the valves would still provide a suction path to the SI pumps and
allow for successful completion of the task.
Item #2 Control Room Job Performance Measure (JPM F): Perform Post Trip Equipment
Checks with a Failure of Slave Relays and EGTS Fans to Start.
Post-Examination Comment:
During performance of JPM F, two applicants failed to close dampers 1-FCO-65-52, Annulus
Vacuum fan 1A Isolation Damper and 1-FCO-65-53, Annulus Vacuum fan 1B Isolation
Damper due, in part, to the applicants using provisions contained in EPM-4 USERS GUIDE
APPENDIX E APPROVED PRUDENT OPERATOR ACTIONS. In the original version of the
JPM, steps to close 1-FCO-65-52 and 1-FCO-65-53 were marked CRITICAL due to the belief
that the dampers, when closed, allowed EGTS to perform the design function of maintaining the
annulus at a slight vacuum during a LOCA and prevented the possibility of an unfiltered release
from the annulus to the Auxiliary Building ventilation stack (atmosphere) under certain
conditions. After reviewing drawings 47W866-1, 47W866-10 and 47W866-11, Auxiliary Building
Exhaust Vent Isolation Dampers FCO-30-49 and FCO-30-55, located downstream of 1-FCO-65-
and 1-FCO-65-53 were discovered to provide the isolation function for Auxiliary Building
ventilation. Additionally, Auxiliary Building Exhaust Vent Isolation Dampers FCO-30-49 and
FCO-30-55 will receive an automatic closure signal upon receipt of a Phase A Isolation signal,
which occurred during the postulated condition of this JP
- M. Therefore, closure of 1-FCO-65-52
and 1-FCO-65-53 would not be critical since the downstream path would be isolated upon
receipt of Phase A Isolation. Sequoyah requests the wording on JPM step 11 and 12 be
changed to reflect this discovery.
Condition Report No. 1154410 was initiated for Sequoyah Initial License Training to evaluate
training on the provisions contained in EPM-4, USERS GUIDE APPENDIX E APPROVED
PRUDENT OPERATOR ACTIONS and what the implications of utilizing prudent operator
actions may result in.
NRC Resolution:
The licensees recommendation to change the wording of JPM steps 11 and 12 is accepted. The
facility-provided reference supports that Auxiliary Building ventilation isolation is provided by
Auxiliary Building Exhaust Vent Isolation Dampers FCO-30-49 and FCO-30-55. Since 1-FCO-
65-52 and 1-FCO-65-53 are not relied upon to prevent an unfiltered release, their operation is not
critical to completion of the task.
