Abstract
A remote-controlled mobile cleaning device for removal and collection of high radioactive waste debris in a spent nuclear fuel process and fabrication area, such as a hot-cell, is disclosed. The device includes navigation means for moving it to the desired cleaning location and climbing over such obstacles as electrical cables and pneumatic tubes placed on the hot-cell floor to be cleaned, suction and collection means for dislodging, filtering, and capturing high radioactive waste debris, and cover means for protecting suction and collection means. The device that is operated by remote control cleans and collects loose dry spent nuclear fuel powder and other high-radioactive waste debris adhered to both the contaminated in-cell floor and the in-cell spent nuclear fuel process and fabrication equipment, without spreading inside the hot-cell.
