Problems solved by technology

A disadvantage in this respect is the relatively large width of the nuclear plant pool, for example 20m to 30m, which necessitates truck cranes or gantry cranes traveling on rails with correspondingly large spans
Furthermore, pool edge accessibility is very limited by local conditions, e.g. by adjoining buildings or existing gantry cranes

Embodiment Construction

[0036] figure 1 A first example floating platform 10 is shown in side view. At the metal frame 32 , cuboid floating bodies 12 , 14 are arranged on both sides of its axial center, and these floating bodies keep the floating platform 10 floating in the water at least partially above the water surface 34 . Between the buoys 12 , 14 arranged at a distance relative to each other, a towing device 16 is provided, in this case comprising a winch with a drive, which can be moved by a rope guided via a winch wheel 18 . The pump 20 fixed at the end of the rope is hoisted up or down in the direction of the arrow 22 . The pump 20 is connected via a suction hose 24 to a storage tank, not shown, into which the pumped water is introduced.

[0037]The floating platform 10 can be fully adjusted by means of a drive device comprising a plurality of drives 26 , 28 , which, like the towing device 16 , can be remotely controlled via a remote control device (not shown). Partially surrounding dampe...

Abstract

The invention relates to a nuclear facility vessel cleaning device, comprising floating platforms (10,40,62) which is provided with floating bodies (12,14,46,48) and can float in water (80), driving devices (26,28) used to move the floating platforms (10,40,62) on the surface of a nuclear facility vessel (78) which is filled with water and is to be cleaned, towing devices (16,54) which are connected with the floating platforms (10,40,62), pumps (20,52,66) which can be vertically hung up and down (22) through the towing devices (16,54), the pumps being provided with suction hose (24,70) which are connected with the pumps on the first tail ends and are used to clean the bottom of the nuclear facility vessel (78), a remote control device (86) used to at least remote control the driving devices (26,28) and the towing devices (16,54), and an optional fixed external storage tank (76). The suction hoses (24,70) optimally at least indirectly access the fixed external storage tank (76) by the second tail ends of the suction hoses.

Description

technical field [0001] The invention relates to a nuclear facility pool cleaning equipment. It is known that burnt spent fuel is temporarily temporarily stored in nuclear facilities where nuclear reactions are carried out, such as nuclear power plants. Such storage is usually done in pools of water or in nuclear facility pools, or outdoors outside buildings, depending on local conditions. Background technique [0002] Owing to the unavoidable ingress of organic particles such as leaves, dirt, dust or the like outdoors, sludge-like deposits accumulate over time in pools of such nuclear facilities. The sludge consists mostly of organic material and a small portion of highly radioactive fuel particles. Temporary storage of spent fuel is usually stored in storage containers of the trough dump type made of steel plates, which are in themselves indeterminate locations in the pool of nuclear facilities. Suspended matter in the water limits the view into the pool making visual po...
