The inventive container includes a housing, the upper part of which is made with a hollow under the lid, sealed the lid and lifting the nodes located on the housing. The walls of the cover and the side walls of the grooves of the housing have a wedge-shaped protrusions shifted by step relative to each other, and between the projections made clearance for filling sealing binder. The walls of the housing and cover are made of a thickness not less than 200 mm, while the body is made in the form of a parallelepiped with rounded corners. 2 Il.

The invention relates to nuclear energy, in particular to containers for disposal and transportation of solid radioactive waste.

Known reinforced concrete container [1] contains a cylindrical housing and a sealed lid, and sealing in the area of contact of the cover with the body through heat fusible filler fuel elements with its subsequent cooling after installing the cover, which pass the refrigerant through the cooling pipes.

Also known reinforced concrete container [2] comprising a housing, upper part of which is made with a hollow under the lid, sealed the lid and lifting the nodes located on the body.

This container also does not provide a reliable sealing of the cover and the housing, and the hull form is not an efficient use of space repositories for radioactive waste in containers.

The invention allows to significantly simplify the design of the housing and the cover and to ensure reliable sealing of the container in the zone of contact between the housing and cover. In addition, the proposed design prevents damage to the walls of the container when it is moving and transportation and with maximum efficiency to use the area of warehouse premises in the storage of radioactive waste.

The walls of the cover and the side walls of the grooves of the housing have a wedge-shaped protrusions shifted by step relative to each other, and between the projections made clearance for filling sealing binder, and the walls of the housing and cover are made of a thickness of 200 mm, while the body is made in the form of a parallelepiped with rounded corners.

On paediatric waste includes a housing 1 with an airtight cover 2. The walls of the housing and cover is made of heavy armocement reinforced several horizontal layers of wire reinforcement and vertical grids forming cells. The wall thickness of the housing 1, the bottom and top 2 should be not less than 200 mm, which provides radiation safety. In the upper part of the housing 1 has a recess under the cover 2. The walls of the recess of the casing and the wall of the cover 2 are wedge-shaped projections 3 and 4, respectively. The projections 3 of the deepening housing offset from the protrusions 4 covers on the step height. Between the projections 3 and 4 made the gap 5, which is filled with a sealing binder solution expanding the alumina cement. The body 1 of the container is made in the form of a parallelepiped with rounded corners, which allows the most efficient use of the storage area at the disposal of containers with radioactive waste and the corners rounded protects the container from damage when it is moving and transportation does not occur chipping of corners with bumps and falls. For ease of handling and transportation of the container on its walls made lifting nodes 6.

Radioactive waste, prednaznatchena cover 2 and the gap 5 between the wedge-shaped projections 3 and 4 is filled with a solution of an expanding alumina cement, which after hardening hermetically connects the cover 2 with the body 1. In this way the container can be moved, transported and stored.

Thus, the proposed reinforced concrete container for storing solid radioactive waste has a simple structure in the coupling zone of the cover with the chassis, which simplifies its manufacture and sealing, filling the gap between the cover and the recess in the housing sealing binder does not require additional costs, and execution of the shell in the form of a parallelepiped with rounded corners protects it from damage and allows you to effectively use the space at disposal.

Reinforced CONCRETE CONTAINER FOR the DISPOSAL of SOLID RADIOACTIVE WASTE, comprising a housing, upper part of which is made with a hollow under the lid, sealed the lid and lifting the nodes located on the housing, characterized in that the wall of the cover and the side walls of the grooves of the housing have a wedge-shaped protrusions shifted by step relatively to each other, and between the projections made clearance for filling sealing binder, and the walls of the housing and cover are made of a thickness not less than 200 mm, and the building
