Container for storing hazardous material and a method of enclosing hazardous material in a concrete container body

摘要

A container for storing hazardous material and a method of enclosing hazardous material in a concrete container body defining a storage space and having an access opening for introducing the hazardous material in the storage space comprises fluid-tight sealing of the storage space by introducing a closure body of concrete in the opening subsequent to the introduction of the hazardous material. The closure body is formed by casting concrete in the access opening subsequent to the introduction of the hazardous material in the storage space and allowing the concrete to harden while supplying heat to the portion of the concrete container body surrounding the access opening.
