Method of maintaining ice in a pressurized water reactor

摘要

A vibrating assembly for vibrating an ice basket of a pressurized water reactor comprises first and second vibrators and a bracket operatively connected to the vibrators. The bracket includes a horizontally extending first armature portion and a horizontally extending second armature portion pivotably attached to the second armature portion. The first and second armature portions have clamps extending downwardly from each of their ends, and each of the clamps includes an arcuate groove extending vertically upwardly from its bottom surface to engage the rim of the ice basket. An attachment portion extends vertically upwardly from and is formed unitarily with the first armature portion, the vibrators being attached to the sides of the attachment portion. The clamps extending from the second armature portion are pivotably connected to and are also laterally adjustable with respect to the first and second ends of the second armature portion. In use the vibrator assembly is attached to the rim of the ice basket by adjusting the positions of the clamps to fit the rim and then securing the rim in the clamps. The vibrators are then activated to free the ice in the ice basket. While the vibrators are activated, the ice basket is pulled from above by exerting an upward force on the bracket and is pushed from below.
