Remote-controlled mobile cleaning apparatus for removal and collection of high radioactive waste debris in hot-cell

A remote-controlled mobile cleaning apparatus for removing and collecting highly contaminated radioactive waste debris deposited on the hot-cell floor and the surface of spent nuclear fuel process and fabrication equipment located on said hot-cell floor where humans are inaccessible due to the high radiation level of spent nuclear fuel, comprising:

• a navigation means provided at a lower portion of said apparatus for moving on a surface of said hot-cell floor;
• a suction and collection means connected with the navigation means for dislodging, sucking and collecting highly contaminated radioactive waste debris;
• and
• a cover part mounted on the top of the suction and collection means so as to cover and protect the suction and collection means, wherein said suction and collection means comprises:
• a primary suction unit to dislodge and suck radioactive waste debris adhered to the surface of the hot-cell floor;
• a flexible suction unit to clean up areas where the primary suction unit is inaccessible or the surface of the equipment located on the hot-cell floor;
• a primary collection unit to firstly filter and store radioactive waste debris sucked both by the primary suction unit and by the flexible suction unit;
• a secondary collection unit to filter and capture more fine radioactive waste debris filtered from the primary collection unit;
• a blower unit to generate a suction force for the suction and collection means;
• and
• a housing holding all of the above units,
• whereby each unit is separately constructed in modules and connected to each of said other units by first, second, third, and fourth feed pipes in sequence.
