FIELD: process engineering.
SUBSTANCE: invention relates to safety measures in transfer of used fuel rod arrays from transport shells into those of storage and may be used in water-filled used nuclear fuel storages at nuclear fuel recovery plants, or at nuclear power stations as emergency tools. Proposed device comprises receiving pool, moving platform with running arranged thereunder, lifting device, protective barrel with chamber open on pool side, grip arranged inside said barrel and jointed to bar lower part, bar being mounted on lifting devices, and rod reciprocation drive arranged inside said barrel. Said grip is furnished with fixed and moving jaws, fixed jaws are secured to protective barrel while moving jaws are articulated with cross-arm and fitted in inclined grooves of guide ribs connected to aforesaid barrel. Mating bearing surfaces of jaws are composed of corrugated inclined surfaces with equal angle of inclination.
EFFECT: higher reliability and safety.
