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 Full-HD cameras mounted on a frame is e.g. placed above an 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.
