UA8539U - Protected transport container for solid radioactive waste - Google Patents

Abstract

The proposed protected transport container for solid radioactive waste contains a casing, a cover, and hoisting elements installed at the casing. The walls, bottom, and cover of the casing are made of reinforced concrete. To reinforce concrete, a framework from reinforcing bars and 3 à 5 in parallel arranged reinforcing nets from thin wire is used. The thickness of the walls, bottom, and cover of the casing is no less than 150 mm. In the cover, two stepped through openings are provided, which are closed by plugs. To the reinforcing bars at the lower part of the cover, a bar net is welded. The proposed design of the container provides a possibility to compact waste and prevent leak of waste when filling the container with concrete. As a result, the net volume of the container is more efficiently used, and the protective characteristics of the container are improved.

Description

Description of the invention

A useful model relates to nuclear energy, namely to protective containers, which are designed for 2 transportation and long-term storage and burial of radioactive waste. The container is mainly used for burying highly radioactive waste placed in standard barrels, which are used as disposable containers for superpressing - the so-called "pancakes". As a result of superpressing, the height of the barrel is reduced by five times, which allows more efficient use of the volume of the container and increases the coefficient 70 A well-known reinforced concrete container for burying solid radioactive waste, containing a body with rigging units, the upper part of which is made with a recess for a sealed lid, and the walls of the lid and the side walls of the recess of the housing have wedge-shaped protrusions, offset by a step from each other, between with which the gap is made to be filled with a sealing binding material, and the walls of the case and the cover have a thickness of at least 200 mm. At the same time, the case is made in the form of a parallelepiped with rounded corners (Patent 72 of the Russian Federation Mo2056653, IPC 6 C21E5/005, 1996).

The well-known transport-protective container for solid radioactive waste, consisting of a body, a hermetic cover and rigging units, which are located on the body, and the cover, walls and bottom of the body are made of concrete with combined reinforcement, which includes a spatial reinforcing frame, consisting of reinforcing bars rods with a thickness of 5-1 mm, on both sides of which, parallel to the inner and outer planes of the cover, walls, and bottom of the case, there is a layer of 3-5 rows of mesh made of thin wire 0.6-1.2 mm thick with a cell size from 7 to 20 mm, while the width of the spatial reinforcing frame is set based on the calculation of ensuring the thickness of the protective layer of concrete in the range of 5-1Omm, and the thickness of the walls of the case, bottom and cover is at least 15О0mm (Patent of Ukraine Mo59479, IPC 7 5215/0005, 2003).

The disadvantage of the described containers is the impossibility of sealing waste, unreliable sealing of the containers in the 29 zone of contact of the body with the lid and, as a result, an insufficient level of protective properties. -at

The useful model is based on the task of improving the transport protective container for solid radioactive waste, in which, due to the new design of the lid, the possibility of compacting the waste is achieved, which allows more efficient use of the container's capacity and increases the level of protective properties of the container. at

The task is achieved by the fact that in a transport protective container for solid radioactive waste, which consists of a body, a hermetic cover and rigging units, according to a useful model, the cover has two step-through holes and two plugs, and a mesh is welded to the reinforcement of the lower part of the cover. which consists of a spatial reinforcing frame made of rods. Moreover, the lid, walls, and bottom of the housing (Ge) are made of concrete with combined reinforcement, which includes a spatial reinforcing frame consisting of 30 reinforcing rods, on both sides of which, parallel to the inner and outer planes of the lid, walls, and bottom of the housing, there is a layer of 3-5 rows of thin wire mesh, and the thickness of the walls of the case, bottom and cover is at least 150 mm. "

Figure 1 shows a transport protective container for solid radioactive waste in section; in Fig. 2 8 - this container, top view. 70 The transport-protective container for solid radioactive waste contains a housing 1 with a hermetically sealed lid 2. In the upper part of the housing, a stepped recess is made for the installation of the lid 2, which

"Iz" is insulated in the case. In the lower part of the cover, a grid Z is attached to its reinforcement, made in the form of a welded spatial frame made of rods with a diameter of 8 and 1 Ω. The mesh is designed to press the waste and to prevent the waste from floating when the container is filled with concrete. In the center of cover 2, two step-through holes are made for installing plugs 4 after pouring concrete into one of the holes. The body of the container has the shape of a parallelepiped with rounded corners. For ease of transportation on the walls 4! the container is equipped with rigging units 5. The lid of the container, the walls and the bottom of the case are made of concrete, reinforced with metal rods with a diameter of 8, 10 and 12 mm. o After filling the body of the container with "pancakes", a lid is installed on it and concrete is poured through one hole (Che) 20. Concrete is poured until the container is completely filled, after which the holes are closed with plugs. In this way, dense packing and reliable sealing of the container with highly radioactive waste is achieved.
