INCLINED ELEVATOR OF NUCLEAR REACTOR Russian patent published in 2017 - IPC G21C19/32 G21F9/34 

FIELD: transportation.

SUBSTANCE: invention relates to the field of nuclear equipment and may be used within handling equipment of a nuclear reactor. The inclined elevator of the nuclear reactor comprises a trolley 1 with a cartridge 2 for a spent fuel assembly, which is moved along a rail track 3 in an inclined corridor 4 with the help of a cable 8. At the inlet to the inclined corridor 4 there is a guide unit equipped with an asymmetric gutter for cable passage and installed in respect to the rail track at the angle β, meeting the following condition: tgβ=t/πD, where β - angle of inclination of the guide unit to the rail track; t - pitch of grooves for the cable on a drum; D - drum diameter, and axis of symmetry of the guide unit gutter is located along the trajectory of the cable motion.

EFFECT: improved rectilinearity of cable movement with increased angle of inclination of an inclined corridor in an inclined lift, reduced dimensions of openings in walls of a reactor room building and a spent fuel storage pond, through which a trolley travels.
