ES-401 Record of Rejected K/As Form ES-401-4 Tier / Randomly Reason for Rejection Group Selected K/A Tier 1 / 011EA1.01 Large Break LOCA Group 1 Ability to operate and monitor the following as they apply to a Large Break LOCA:

Control of RCS pressure and temperature to avoid violating PTS limits During a Large Break LOCA there is no direct ability to control RCS pressure and temperature to avoid violating PTS limits.

Chief Examiner randomly selected 011EA1.06 D/Gs Tier 1 / 037AK3.08 037 Steam Generator (S/G) Tube Leak Group 2 Knowledge of the reasons for the following responses as they apply to the Steam Generator Tube Leak:

Criteria for securing RCP PBNP Steam Leak procedure completely rewritten and no longer contains criteria for securing reactor coolant pumps Chief Examiner randomly selected 037AK3.07 Actions contained in EOP for S/G tube leak Tier 2 / 003A4.03 Reactor Coolant Pump System (RCPS)

Group 1 Ability to manually operate and/or monitor in the control room:

RCP lube oil and lift pump motor controls Both Tier 2/Group 1 system questions for 003 (Reactor Coolant Pump System) focused on the lube oil subsystem of the RCP, with these being only direct sample of the RCSS, this subsystem is being oversampled.

Chief Examiner randomly selected 003A4.05 RCP seal leakage detection instrumentation Tier 2 / 022A2.03 Containment Cooling System (CCS)

Group 1 Ability to (a) predict the impacts of the following malfunctions or operations on the CCS; and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those malfunctions or operations:

Fan motor thermal overload/high-speed operation PBNP Containment fans do not have direct thermal overload protection or different fan speeds.

Chief Examiner randomly selected 022A2.04 Loss of service water

ES-401 Record of Rejected K/As Form ES-401-4 Tier 2 / 022A2.06 Containment Cooling System (CCS)

Group 1 Ability to (a) predict the impacts of the following malfunctions or operations on the CCS; and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those malfunctions or operations:

Loss of CCS pump PBNP Containment fans do not have direct thermal overload protection or different fan speeds.

Chief Examiner randomly selected 022A2.04 Loss of service water Tier 2 / 061K2.03 Auxiliary / Emergency Feedwater (AFW) System Group 1 Knowledge of bus power supplies to the following:

AFW diesel driven pump PBNP does not have a diesel driven auxiliary feedwater pump.

Chief Examiner randomly selected 061K2.02 AFW electric drive pump Tier 3 G2.3.11 Radiation Control Ability to control radiation releases.

Several questions already have this component included in them. Could not author a non-system specific question on this topic.

Chief Examiner randomly selected G2.3.13 Knowledge of radiological safety procedures pertaining to licensed operator duties, such as response to radiation monitor alarms, containment entry requirements, fuel handling responsibilities, access to locked high-radiation areas, aligning filters, etc.
