Fuel Handling Flashcards
Given the following plant conditions: Mode 6. Refueling operations in progress. The refueling machine is moving to retrieve an irradiated fuel assembly in the upender. The CRS notifies the LSRO that there is a rapidly lowering fuel pool level and has implemented the LMEOP. The CRS directs the LSRO to place the fuel in a safe condition, and close PCN-V118 Fuel Transfer Tube Isolation Valve. Which of the following describes the required actions for the proper safe location of the fuel and location of the upender/carriage? The LSRO takes action to place the:
A. Fuel in the reactor vessel and retain the fuel carriage in containment.
B. Fuel in the upender and retain the upender vertical. Fuel Carriage either on the Fuel poolside or Containment.
C. Fuel in the intermediate storage rack and send the fuel carriage to the Fuel Building.
D. Fuel grappled at the uplimit on the RFM and lower the upender horizontal.
Answer: A
The Unit is in Mode 6 with core off-load is in progress. Chemistry calls and reports that the Boron concentration is 2290 ppm in the RCS and 3010 in the refueling canal. The COLR limit is specified as 3000 ppm. What are all the action(s) if any that should be taken?
A. Suspend positive reactivity additions as soon as possible.
B. Initiate action to restore Boron concentration to within limits, suspend positive reactivity additions and core alternations immediately.
C. No action is required, refueling boron concentration is in specification.
D. Initiate action to restore Boron concentration to within limits, suspend core alternations within one hour.
Answer: B
The Concrete Cask heat removal system is OPERABLE if the:
A. difference between the average CONCRETE CASK air outlet temperature and ISFSI ambient temperature is greater than or equal to 102°F.
B. highest ISFSI outlet temperature is less than 102°F.
C. difference between the average CONCRETE CASK air outlet temperature and ISFSI ambient temperature is less than or equal to 92°F.
D. difference between the average CONCRETE CASK air outlet temperature and ISFSI ambient temperature is less than or equal to 102°F.
Answer: D
Which one of the following Radiation Monitors becoming inoperable would require suspension of core alterations during core offload? ASSUME all other conditions are acceptable/normal for the evolution.
A. RU 37, Power Access Purge Area Monitor
B. RU 33, Refueling Machine Area
C. RU 29, Control Room Ventilation Intake Monitor
D. RU 143, Plant Ventilation Low Range Monitor
Answer: B
