FIELD: transport.SUBSTANCE: proposed damper relates to protective means used at transportation of transfer jackets filled with fresh fuel rod bundles fir nuclear reactor. This damper comprises case 1 with over 2 composed of cylindrical barrels with top section 3 of said case and base 4, cover fasteners composed by bayonet lock 7, 6 and damping units 8, 12 with shockproof elements secured at case and cover end faces and case and cover side surfaces. Damping elements 8 at case and cover end surfaces are composed by horizontal circular plates 9 with OD varying in stepwise manner from bottom to top. Plate-like ribs 10, 11 with pre-curved mid part are arranged between said plates 9. Damping elements 12 at outer side surface of the case and cover are composed of belt elements consisting of coaxial cylindrical rings 13. Shockproof elements composed of plate-like radially fitted ribs 14, 15 with pre-curved mid part.EFFECT: decreased risks of damage in transportation and shifting.5 cl, 8 dwg |
