Abstract

Continuous procedure to prepare and collect particulate material from a gas stream that transports it, characterized in that it comprises the steps of (a) directing the gas stream towards two conduction zones, each conduction zone having a size that avoids condition of nuclear criticality, (B) filtering the particulate material from the gas stream in the conduction zones, (or) periodically blowing to release the particulate material in the conduction zone, (d) collecting the particulate material in a separate containment area, detachably connected to each conduction area, each containment area having a size that avoids a condition of nuclear criticality, (e) close the passage from the conduction areas to the connected containment areas and (f) separate the material in particles collected from the container areas.
