ES-401 Record of Rejected K/As Form ES-401-4 Tier /
Group Randomly Selected K/A Reason for Rejection Tier 2/Group 2 (RO) 272000 (SF7, SF9 RMS) Radiation Monitoring:
K3.08 Knowledge of the effect that a loss or malfunction of the RADIATION MONITORING System will have on following: Auxiliary building ventilation.
Question R64. We do not have any relationships between radiation monitoring and Aux Building ventilation. Dont have Aux Building ventilation.
REPLACED by 272000 (SF7, SF9 RMS) Radiation Monitoring: K3.10 Knowledge of the effect that a loss or malfunction of the RADIATION MONITORING System will have on following: Control room ventilation.
Tier 2/Group 1 (RO) 205000 (SF4 SCS)
Shutdown Cooling A4.12 Ability to manually operate and/or monitor in the control room:
Recirculation loop temperatures.
Question R29: We don't monitor RR loop temps while in SDC (loop temps are not reliable without forced RR flow). Our plant is not analyzed for RR pumps to be running in SDC REPLACED by 205000 (SF4 SCS) Shutdown Cooling: A4.11 Ability to manually operate and/or monitor in the control room: Heat exchanger cooling flow.
Tier 2/Group 1 (SRO) 205000 (SF4 SCS)
Shutdown Cooling A2.11 Ability to (a) predict the impacts of the following on the SHUTDOWN COOLING SYSTEM (RHR SHUTDOWN COOLING MODE) ;
and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those abnormal conditions or operations:
Recirculation pump trips.
Question S86:Our plant is not analyzed for RR pumps to be running in SDC, so I cant meet this K/A because the conditions for a trip would not occur.
REPLACED by A2.06 Ability to (a) predict the impacts of the following on the SHUTDOWN COOLING SYSTEM (RHR SHUTDOWN COOLING MODE) ; and (b) based on those predictions, use procedures to correct, control, or mitigate the consequences of those abnormal conditions or operations: SDC/RHR pump trips
ES-401 Record of Rejected K/As Form ES-401-4 Tier 1/Group 1 (RO) 295004 (APE 4)
Partial or Total Loss of DC Power K3.02 Knowledge of the reasons for the following responses as they apply to PARTIAL OR COMPLETE LOSS OF D.C. POWER:
Ground isolation/fault determination.
Question R03: No procedural guidance for ground fault isolation/fault determination for operators. At Fermi 2 this is done under maintenance.
All an operator does is write a CARD.
REPLACED by K3.03 Knowledge of the reasons for the following responses as they apply to PARTIAL OR COMPLETE LOSS OF D.C.
POWER: Reactor SCRAM: Plant-Specific.
Tier 2/Group 1 (SRO) 300000 (SF8 IA)
Instrument Air G4.46 Ability to verify that the alarms are consistent with the plant conditions.
Question S90: Air system is highly sampled on this sample plan. (S87)
(R08) (R46) The K/A for S90 risks double jeopardy on this topic.
Recommend keeping the generic (G4.46) and changing the System to 264000 (SF6 EGE) Emergency Generators (Diesel/Jet) EDG which is the system on the sample plan above Instrument Air to minimize the impact on the sample plan.
Accepted by chief examiner.
Tier 2/Group 2 (RO) 234000 (SF8 FH)
Fuel-Handling Equipment G 2.1.27 Knowledge of system purpose and/or function.
Question R61: Question was found to be Unsat (U) due to low LOD (LOD 1). During onsite validation week, no suitable replacement could be found or written. Decision was made to replace K/A in the sample plan.
REPLACED with Generic K/A 2.1.28 Knowledge of purpose and function of major system components and controls. 4.1/4.1
