Abstract
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.

A container for storing hazardous material in a closed storage space, comprising
- a concrete container body (11) forming the storage space (12) and having a mouth portion (11A) defining an access opening (13) for insertion of the hazardous material (C), and
- a concrete closure body receivable in the opening to form a fluid-tight seal for the storage space (12),
- characterized by
- a heater (18) disposed in the container body (11) around the access opening (13) for heating the mouth portion (11A), and
- the container body being reinforced by a circumferential metal reinforcement (16) at the mouth portion (11A) of the container body (11), the reinforcement being disposed within the heating range of the heater (18), whereby it will be heated as a result of the heating of the mouth portion (11A).
A method enclosing of enclosing hazardous material in a concrete container body (11) defining a storage space (12) and having an access opening (13) for introducing the hazardous material (C) in the storage space, comprising fluid-tight sealing of the storage space (12) by introducing a closure body (19) of concrete in the access opening (13) subsequent to the introduction of the hazardous material, characterized by casting concrete in the access opening (13) subsequent to the introduction of the hazardous material (C) in the storage space (12), and allowing the concrete to harden while supplying heat to the portion (11A) of the concrete container body (11) surrounding the access opening (13).
A container for storing hazardous material in a closed storage space, comprising
- a concrete container body (11) forming the storage space (12) and having a mouth portion (11A) defining an access opening (13) for insertion of the hazardous material (C), and
- a concrete closure body receivable in the opening to form a fluid-tight seal for the storage space (12),
- characterized by
- a heater (18) disposed in the container body (11) around the access opening (13) for heating the mouth portion (11A),
- in which the heater (18) extends substantially throughout the mouth portion (11A) and past the mouth portion into the adjoining portion of the container body (11).
