Beschreibung
Zusammenfassung:The invention relates to the field of atomic engineering, particularly to the equipment for leakage detection and repair of a damaged inner lining of NPP spent fuel pools filled with water. The arrangement and system for repairing the lining of a spent fuel pool, mainly the walls and bottom thereof, are additionally equipped with devices that are not submerged to the spent fuel pool, including welding equipment, and devices submerged to the spent fuel pool, including a submersible repair platform for the working mechanism installation. The working mechanism is equipped with a device for cleaning of weld seams and the surface of the spent fuel pool, and a wire cutting device, comprising a container for collection of cuttings and a pump for particulate removal. The leak sealing device is arranged in the form of a small-scale welding assembly connected to the welding equipment, and the submersible repair platform is equipped with means for its attachment to the surface of the spent fuel pool. The arrangement for repairing the lining of a spent fuel pool includes a submersible repair robot with a working unit installed on it. The invention enables to enhance the repair quality and reliability.
