TRANSPORT AND STORAGE CASK FOR LOW AND MEDIUM LEVEL RADIOACTIVE WASTE, AND A METHOD OF FILLING A TRANSPORT AND STORAGE CASK

摘要

Abstract of the DisclosureA transport and storage container for low and mediumlevel radioactive waste is sealed with an external cover afterbeing charged with a receptacle insert. The receptacle inserthas a cup-like configuration and is arranged in the storagecontainer and adapted directly to receive the radioactivewaste. The storage vessel and the receptacle insertconjointly define an annular space therebetween. The storagecontainer must be appropriate for remotely-controlled handlingand must have the greatest possible capacity per drum. Forthis purpose the top of the receptacle insert has a radiallyextending centering ring at the edge of its opening withsegment-like recesses disposed in spaced relationship to eachother around its periphery. The wall of the insert tapersdownwardly toward the base thereof. A supporting ring extendsaround the outer periphery and is arranged on the externalsurface of the insert in spaced relationship to the centeringring and its outer diameter is greater than the inner diameterof the centering ring. The invention is also directed to amethod of charging such a container for low and medium levelradioactive waste.17
