4-FACE FUEL INSPECTION

The 4-FACE Fuel Inspection is performed during regular offload in a PWR to find failed fuel. A system of four HD cameras mounted on a frame is placed above the upender to record a video of all four sides and the bottom nozzle of each fuel assembly passing by. This gives an immediate verification of fuel assembly integrity, without affecting the critical path.

Applications

• Quad-side fuel inspection during regular offload, without affecting the critical path
• 5th camera or tilt function for bottom nozzle inspection
