ES-401 Record of Rejected K/As Form ES-401-4 Tier /

Group Randomly Selected K/A Reason for Rejection 1 / 1 (RO #6)

APE26AA1.05 Loss of Component Cooling Water (CCW), Ability to operate and / or monitor the following as they apply to the Loss of Component Cooling Water: The CCWS surge tank, including level control and level alarms, and radiation alarm.

Recommended New K/A: APE026AA1.06 Loss of Component Cooling Water (CCW), Ability to operate and / or monitor the following as they apply to the Loss of Component Cooling Water: Control of flow rates to components cooled by the CCWS Justification Statement: The only way to test all 3 of these items together is a RCS to CC in leakage question which is being tested on the 2018 CERT under a different K/A. An additional operationally valid question cannot be developed without overlap 1 / 1 (RO #10)

APE054G2.1.31 Loss of Main Feedwater (MFW) Ability to locate control room switches, controls, and indications, and to determine that they correctly reflect the desired plant lineup.

Recommended New K/A: APE054G2.1.25 Loss of Main Feedwater (MFW), Ability to interpret reference materials, such as graphs, curves, tables, etc.

Justification Statement: Testing the ability to locate control room switches, controls, and indications, and to determine that they correctly reflect the desired plant lineup on a written exam while maintaining plausible distractors is not viable.

1 / 2 (RO #19)

APE003AK1.10 Dropped Control Rod. Knowledge of the operational implications of the following concepts as they apply to Dropped Control Rod: Definitions of core quadrant power tilt.

Recommended New K/A: APE003AK1.15 Dropped Control Rod. Definition and application of power defect.

Justification Statement: Cant test in a written question without overlap with the Certification examination.

2 / 1 (RO #36) 010A3.01 Pressurizer Pressure Control System (PZR PCS). Ability to monitor automatic operation of the PZR PCS, including: PRT temperature and pressure during PORV testing.

Recommended New K/A: 010A3.02 Pressurizer Pressure Control System: Ability to monitor automatic operation of the Pzr PCS including: Pzr Pressure.

Justification Statement: Byron does not do PORV testing in a way that results in changes to the PRT temperature or pressure.

ES-401 Record of Rejected K/As Form ES-401-4 2 / 2 (RO #58) 016A2.04 Non-Nuclear Instrumentation System (NNIS). Ability to (a) predict the impacts of the following malfunctions or operations on the NNIS; and (b) based on those predictions, use procedures to correct, control or mitigate the consequences of those malfunctions or operations: Voltage to instruments, both too high and too low.

Recommended New K/A: 016A2.01 Non-Nuclear Instrumentation System (NNIS). Ability to (a) predict the impacts of the following malfunctions or operations on the NNIS; and (b) based on those predictions, use procedures to correct, control or mitigate the consequences of those malfunctions or operations: Detector failure.

Justification Statement: K/A requires Voltage to instruments, both too high and too low. Testing both in one question limits the operational validity of the question.

1 / 1 (SRO

  1. 76)

EPE007G2.4.50 Reactor Trip. Ability to verify system alarm setpoints and operate controls identified in the alarm response manual.

Recommended New K/A: EPE007G2.4.8 Reactor Trip.

Knowledge of how abnormal operating procedures are used in conjunction with EOPs.

Justification Statement: A candidate does not perform this action in the SRO role.

1 / 1 (SRO

  1. 81)

WE05G2.4.2 Loss of Secondary Heat Sink. Knowledge of system set points, interlocks and automatic actions associated with EOP entry conditions.

Recommended New K/A: WE05G2.4.16 Loss of Secondary Heat Sink. Knowledge of EOP implementation hierarchy and coordination with other support procedures or guidelines such as, operating procedures, abnormal operating procedures, and severe accident management guidelines.

Justification Statement: No credible way to test this K/A in a written question to the SRO level.

2 / 2 (SRO

  1. 91) 014G2.1.19 Rod Position Indication System (RPIS). Ability to use plant computers to evaluate system or component status.

Recommended New K/A: 014G2.1.45 Rod Position Indication System (RPIS). Ability to identify and interpret diverse indications to validate the response of another indication.

Justification Statement: No plausible way to write a question to the SRO level. Operations does collect this data but evaluating rod position based on the data is a function of reactor engineering.

ES-401 Record of Rejected K/As Form ES-401-4 2 / 2 (RO #59) 029A3.01 Containment Purge System (CPS). Ability to monitor automatic operation of the Containment Purge System including: CPS isolation.

Recommended New K/A: 029A4.04 Containment Purge System (CPS). Ability to manually operate and/or monitor in the control room: Containment evacuation signal Justification Statement: Cannot develop question for K/A that does not overlap with the actions performed in JPM CR-h.

No additional A3 abilities applicable for system 029, thus selected from A4 Abilities.

2 / 1 (RO #55) 103K3.03 Knowledge of the effect that a loss or malfunction of the containment system will have on the following: Loss of containment integrity under refueling operations.

Recommended New K/A: 103K3.02 Knowledge of the effect that a loss or malfunction of the containment system will have on the following: Loss of containment integrity under normal operations.

Justification Statement: Cannot develop operationally valid question concerning loss of containment integrity at the RO level during refueling operations.

2 / 2 (RO #59) 029A4.04 Containment Purge System (CPS). Ability to manually operate and/or monitor in the control room: Containment evacuation signal.

Recommended New K/A: 029A4.01 Ability to manually operate and/or monitor in the control room: Containment purge flow rate Justification Statement: Deemed a K/A mismatch at on-site validation. Cannot develop operationally valid question for stated K/A. Containment Evacuation Signal does not interact with Containment Purge System at Byron Station.
