ES-401 Record of Rejected K/As Form ES-401-4 Tier / Randomly Reason for Rejection Group Selected K/A Tier 2 / 212000A3.06 Reactor Protection (RPS)

Group 1 Ability to monitor automatic operations of the REACTOR PROTECTION SYSTEM including:

Main Turbine Trip: Plant Specific 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 212000A3.04 System Status lights and alarms Tier 2 / 215005K1.02 Average Power Range Monitor/Local Power Range Monitor (PRMS)

Group 1 Knowledge of the physical connections and/or cause-effect relationships between AVERAGE POWER RANGE MONITOR/LOCAL POWER RANGE MONITOR SYSTEM and the following:

IRM Completely rewritten criteria for securing reactor coolant pumps Chief Examiner randomly selected 215005K1.10 Reactor manual control system: Plant Specific Tier 2 / 239002K5.03 Safety Relief Valves (SRV)

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 239002K5.04 RCP seal leakage detection instrumentation Tier 2 / 300000A2.01 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 400000A2.02 Loss of service water

ES-401 Record of Rejected K/As Form ES-401-4 Tier 2 / 239002-G2.1.28 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 239002-G2.1.20 Loss of service water Tier 3 G2.1.04 G2.1.04 Conduct of Operations Knowledge of individual licensed operator responsibilities related to shift staffing, such as medical requirements, no-solo operation, maintenance of active license status, 10CFR55, etc.

PBNP does not have a diesel driven auxiliary feedwater pump.

Chief Examiner randomly selected G2.1.15 Knowledge of administrative requirements for temporary management directives, such as standing orders, night orders, operations memos, etc.
