FIELD: nuclear engineering; handling radioactive waste.
SUBSTANCE: proposed steel-ferroconcrete container has body, cover deepened in body in a spaced relation with respect to their walls for filling clearances with radiation-resistant packing material, and wedge locks tightly fitting them to one another. Each lock has cylindrical and wedge supports joined together by means of wedge. Separate supports of wedge locks are installed and secured through nonsplit joint on annular steel bases anchored in ferroconcrete structures of body cover. Clearance is expanding downwards and measures in upper part 20-30 mm, angle between side walls being 5-7 deg. Clearance walls have a number of Z-shaped horizontal marks, 2,5 to 3 mm deep. Supports of wedge locks are mounted and secured on separate steel bases, then these assemblies are anchored and concreted to obtain high-strength body-to-cover joint and desired precision and alignment of wedge-lock supports, including those disposed in opposition in container structure. Clearance is inclined to supporting surface of cover at angle of 83-85 degrees; side wall of cover is also beveled from bottom of its annular steel base at angle of 10-15 deg. Container manufacturing process involves assembly and nonsplit jointing (beyond forms) of cylindrical and wedge supports of wedge locks on separate concentrically disposed annular bases followed by installation of assembled supports into forms.
EFFECT: enhanced reliability of sealing and strength of container body-to-cover joint.
