The utility model discloses a multi -functional check out test set of irradiated fuel assembly, include horn mouth adapter, backplane device, XY load transfer platform, reach the diameter of peripheral fuel rod and oxide film thickness measurement's measured module the diameter of peripheral fuel rod and the calibration module of oxide film thickness demarcation. Through the memory card type encrypting/decrypting converter device, clamping mechanism on backplane device contains the bed plate of being satisfied with the horn mouth adapter and is satisfied with the bed plate, bed plate, horn mouth adapter and horn mouth have a perfect understanding along the lift orientation mutually, and the loading lift is taken irradiated fuel assembly or place out in bed plate, horn mouth adapter and horn mouth three's the department of having a perfect understanding at the lift in -process, the irradiated fuel assembly fixed centre gripping of clamping mechanism to placing, on XY load transfer platform was satisfied with the bed plate, calibration module installed on the bed plate, and measured module is satisfied with XY load transfer platform, and XY load transfer platform orders about measured module and removes to doing the locate mode to reaching Y in X to realize the mesh of multi -functional detection.
