Abstract
Apparatus for decontaminating radioactive components comprising an attachment mechanism for completely suspending the apparatus from the tube sheet of a nuclear steam generator, a first drive mechanism for moving the apparatus in a first direction, a second drive mechanism for pivoting the apparatus in a second direction, and a third drive mechanism for moving the apparatus in a third independent direction. The apparatus also comprises a dual nozzle arrangement attached to the third drive mechanism for directing a water-grit mixture toward the component to be decontaminated. The apparatus provides a mechanism for remotely decontaminating the channel head of a nuclear steam generator so as to allow working personnel to enter therein.
