摘要

1. Arrangement for cleaning the surfaces of a nuclear reactor fuel assembly (4) which is disposed in a container (3) filled with liquid, the container (3) peripherally carrying several ultrasonic vibrators (14) whose acoustic waves are directed in the direction of the fuel assembly (4), characterized in that the ultrasonic vibrators (14) are attached to at least two exterior sides (9, 12), situated opposite each other, of the water-filled container (3) which is disposed in a water tank (1), in that the ultrasonic vibrators (14), situated opposite each other in each case, are located on a common central axis (31), in that the container (3) is provided with a pipeline (26, 32) for circulating the water situated within the container and in that a circulating pump (25) and a filter (24) are connected in series in the pipeline (26, 32).
