ES-401 Record of Rejected K/As Form ES-401-4 Page 1 of 2 Tier / Group Randomly Selected K/A Reason for Rejection Tier 1 / Group 1
295021 AK1.02 RO Q9 Facility was unable to develop an operationally valid and discriminating RO level question with 3 plausible distractors to test the selected K/A (Knowledge of the operational implications of the following concepts as they apply to LOSS OF SHUTDOWN COOLING:
Thermal Stratification).
CHIEF EXAMINER randomly re-selected K/A AK1.04 for Q9:
Knowledge of the operational implications of the following concepts as they apply to LOSS OF SHUTDOWN COOLING: Natural Circulation. (IR 3.6)
Tier 1 / Group 1
295031 EK1.02 RO Q16 Facility was unable to develop an operationally valid and discriminating RO level question with 3 plausible distractors to test the concept of Natural Circulation in accordance with the selected K/A (Knowledge of the operational implications of the following concepts as they apply to REACTOR LOW WATER LEVEL: Natural circulation: Plant-Specific), without introducing an overlap/balance of coverage issue with the randomly re-selected K/A for RO Q9.
CHIEF EXAMINER randomly re-selected K/A EK1.01 for Q16:
Knowledge of the operational implications of the following concepts as they apply to REACTOR LOW WATER LEVEL: Adequate core cooling. (IR 4.6)
Tier 2 / Group 1
211000 K1.02 RO Q32 Facility was unable to develop an operationally valid and discriminating RO level question to test the selected K/A (Knowledge of the physical connections and/or cause-effect relationships between STANDBY LIQUID CONTROL SYSTEM and the following: Core plate differential pressure indication).
CHIEF EXAMINER randomly re-selected K/A K1.05 for Q32:
Knowledge of the physical connections and/or cause-effect relationships between STANDBY LIQUID CONTROL SYSTEM and the following: RWCU. (IR 3.4)
Tier 2 / Group 1
212000 A4.15 RO Q35 Facility was unable to develop a question to test the selected K/A (Ability to manually operate and/or monitor in the control room: Recirculation pump trip/EOC RPT), because Fermi does not have EOC RPT instrumentation.
CHIEF EXAMINER randomly re-selected K/A A4.04 for Q35:
Ability to manually operate and/or monitor in the control room: Bypass SCRAM instrument volume high level SCRAM signal. (IR 3.9)
Tier 2 / Group 2
272000 A3.01 RO Q63 Facility was unable to develop a question to test the selected K/A (Ability to monitor automatic operations of the RADIATION MONITORING SYSTEM including: Main steam isolation indications), because the MSL Radiation Monitor Trip has been removed at Fermi.
CHIEF EXAMINER randomly re-selected K/A A3.02 for Q63:
Ability to monitor automatic operations of the RADIATION MONITORING SYSTEM including: Offgas system isolation indications. (IR 3.6)
Tier 2 / Group 2
272000 A3.02 RO Q63 Facility was unable to develop an operationally valid question to test the re-selected K/A (Ability to monitor automatic operations of the RADIATION MONITORING SYSTEM including: Offgas system isolation indications). At Fermi, the MSL High Radiation Trip was replaced by a trip of the Gland Seal Exhauster (GSE), effectively isolating the input from this source into the Offgas System (i.e., resultant inability of the GS System to overcome system D/P following loss of the Exhauster). GSE Trip Instrumentation initiates a trip of the GSEs to limit offsite and control room doses resulting from fuel cladding failure. Question written to test the GSE trip and resultant impact on the Offgas System does not meet the intent of the K/A because there is no Offgas System isolation on High MSL Radiation conditions.
CHIEF EXAMINER randomly re-selected K/A A3.10 for Q63:
Ability to monitor automatic operations of the RADIATION MONITORING SYSTEM including: Lights and alarms. (IR 3.3)
Tier 3 G2.2.39 RO Q70 Facility was unable to develop an operationally valid and discriminating RO level question that would test and maintain a plant-wide generic focus for the selected Tier 3 K/A (Knowledge of less than or equal to one hour Technical Specification action statements for
ES-401 Record of Rejected K/As Form ES-401-4 Page 2 of 2 systems).
CHIEF EXAMINER randomly re-selected K/A G2.2.35 for Q70:
Ability to determine Technical Specification Mode of Operation. (IR 3.6)
Tier 3 G2.4.35 RO Q75 Facility was unable to develop an operationally valid and discriminating RO level question that would test and maintain a plant-wide generic focus for the selected Tier 3 K/A (Knowledge of local auxiliary operator tasks during an emergency and the resultant operational effects).
CHIEF EXAMINER randomly re-selected K/A G2.4.42 for Q75:
Knowledge of emergency response facilities. (IR 2.6)
Tier 3 G2.1.25 SRO Q95 Facility was unable to develop an operationally valid and discriminating SRO level question that would test and maintain a plant-wide generic focus for the selected Tier 3 K/A (Ability to interpret reference materials, such as graphs, curves, tables, etc.).
CHIEF EXAMINER randomly re-selected K/A G2.1.37 for Q95:
Knowledge of procedures, guidelines, or limitations associated with reactivity management. (IR 4.6)
Tier 3 G2.4.21 SRO Q100 Facility was unable to develop an operationally valid and discriminating SRO level question that would test and maintain a plant-wide generic focus for the selected Tier 3 K/A (Knowledge of the parameters and logic used to assess the status of safety functions, such as reactivity control, core cooling and heat removal, reactor coolant system integrity, containment conditions, radioactivity release control, etc.).
CHIEF EXAMINER randomly re-selected K/A G2.4.37 for Q100:
Knowledge of the lines of authority during implementation of the emergency plan. (IR 4.1)
