Question 1

• 0POP02-IA-0001 Instrument Air*
• • *

What are the instrument air compressor Idle / Load pressure setpoints?

Answer 1

• Compressor 11:*
• *Load: 122 psig / Idle: 132 psig**
• Compressor 12:*
• *Load: 119 psig / Idle: 131 psig**
• Compressor 13:*
• *Load: 116 psig / Idle: 130 psig**
• Compressor 14:*
• *Load: 113 psig / Idle: 132 psig**

The question works if you assume all compressors are in idle so pressure must be at least 123 psig. So must add 3 psig to numbers in question.

Question 2

• 0PGP03-ZO-0035 Reduced Inventory Operations*
• • *

During Mid-Loop operations, who must approve work orders that have RCSPA (RCS Perturbation Activities) potential?

Answer 2

Shift Manager

Mid-Loop Coordinator

Question 3

• 0POP05-EO-FRH1 Response to Loss of Secondary Heat Sink*
• • *

While in 0POP05-EO-FRH1, what is required for an adequate bleed and feed?

• (Procedure actually has you establish feed before bleed)

Answer 3

• Adequate Feed:*
• *One Charging Pump**

Two HHSI

• Adequate Bleed:*
• *Two PZR PORVs**

Note:

• To get here the Secondary Heat sink must be required
  
  • (RCS Pressure > SG Pressure AND RCS WR HL Temps > 350 ˚F)
• Also SGs are unavailable to remove heat
  
  • (SG WR Level in ≥ 2 SGs ≤ 50% OR PZR Pressure ≥ 2335 psig)
  • Tries to restore feed if SGs are available

Question 4

• 0POP04-DJ-0001 Loss of Class 1E 125 VDC Power*
• • *

What must be done to declare a Class 1E battery OPERABLE if it was not aligned to an OPERABLE battery charger for > 15 mins?

Answer 4

Ensure 0PSP06-DJ-0001 (Monthly Surveillance Test) completed satisfactorily

Question 5

• 0POP05-EO-FRC2 Response to Degraded Core Cooling*
• • *

While in 0POP05-EO-FRC2 (Response to Degraded Core Cooling), what is the purpose of depressurizing all intact SGs to 305 psig?

Answer 5

Allow LHSI pumps to inject

Allow Accumulators to inject

Question 6

• 0POP04-RC-0001 High RCS Activity*
• • *

What will mitigate the consequences of a high reactor coolant system activity?

Answer 6

• All MODES:*
• *Raise Letdown Flow**

Put Cation Bed in Service

• MODE 5 ONLY:*
• *Put RCPP in service**

Note:
Validated by chemistry samples

Question 7

• 0POP02-EE-0001 ESF DC Distribution System*
• • *

What is the correct order of breaker operation when energizing a battery charger?

Answer 7

Close DC Breaker

Close AC Breaker

Note:
Class 1E Battery chargers should be paralled for ≤ 15 mins.

Question 8

• 0POP04-RC-0002 RCP Off Normal*
• • *

What is the basis for shutting the #1 Seal Leakoff valve 3 to 5 minutes after securing the RCP when the #1 Seal Leakoff flow pegs high?

Answer 8

Ensures the RCP shaft has stopped rotating to minimize damage to the #2 Seal

Question 9

• 0POP08-FH-0009 Core Refueling*
• • *

What are the two responsibilities of the core load supervisor as defined in 0POP08-FH-0009 Core Refueling?

Answer 9

Implementation of the procedure

Concurring with any changes to an approved Fuel Transfer Form (FTF)

Question 10

• 0POP05-EO-FRC1 Response to Inadequate Core Cooling*
• • *

What is checked to determine if core cooling is adequate?

Answer 10

CETs < 1200 ˚F

≥ 2 HL Temps < 350 ˚F

RVWL ≥ 20% Plenum

Question 11

• LCO 3.4.9.3 COMS*
• • *

What relief valve is allowed to replace a PZR PORV while COMS is armed?

Answer 11

RHR Relief in an operating RHR Loop

• Note:*
• Basis in MODE 4: Inadvertent SI signal (One HHSI Pump)
• Basis in MODE 5: Full charging with a loss of letdown

Question 12

• 0POP05-EO-FRH2 Response to SG Overpressure*
• • *

What is the overall strategy for 0POP05-EO-FRH2 Response to SG Overpressure?

Answer 12

Dump Steam from SGs
