FOUR SIDED 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.
