Description

The utility model relates to shielding devices against radioactive radiation, namely to shielding containers designed for the management of solid radioactive waste and serves for their collection, transportation, storage and disposal.

Known device for a similar purpose, similar in use, "Container for radioactive waste" authors Antipov S. N., Bogachev A. A. and others, according to RF patent 137691, IPC G21F 5/00, containing a body with walls and a bottom, a cover with holes concentrically located on it for fasteners and stiffening ribs [1].

This "Container for radioactive waste" does not provide operational safety when handling high-level radioactive waste due to the lack of necessary radiation protection.

Also known is a useful model "Container for radioactive waste", the authors Gataullin R. M., Arustamov A. E. and others, according to the patent of the Russian Federation 120277, IPC G21F 5/00, containing a housing formed by the bottom and a side shell conjugated to its upper end surface with a hermetically sealed cover made with a pipe for supplying cementing material [2].

The disadvantages of this device are the lack of the possibility of stacking and using a forklift.

The prototype of the proposed utility model is "Container for radionuclide sources", authors N. A. Barinova, M. N. Diordiy, according to RF patent No. 155931, IPC G21F 5/00, which is a container for radionuclide sources containing a protective container consisting of a case, a metal container designed to accommodate radionuclide sources [3].

The disadvantages of the selected prototype are the narrowly targeted scope, the complexity of the design, the recyclable waste has limited dimensions, and the container is not intended for reuse.

The objective of the proposed utility model is to eliminate the above disadvantages and create a container for solid radioactive waste.

The technical result of the proposed solution is as follows:

- expansion of the field of application by changing the design of the protective container;

- simplification of the container design due to the use of a lid with hinged joints;

- increase in the size of the disposed solid radioactive waste by changing the closure;

- expansion of the field of application due to the reuse of the container.

The technical result is achieved due to the fact that the body of the protective container is made in the form of a rectangular parallelepiped, while a rectangular ledge is made on the upper edges along the perimeter, the closure is made in the form of a hinged lid with a locking plate having a rectangular ledge on the side faces and covering the body of the protective container from above with a joint in a groove, while connected to the body and the locking plate by a hinge joint. The body of the protective container is equipped with rigging elements. The inner and outer surfaces of the body and lid of the protective container are coated with a coating resistant to decontamination solutions.

FIG. 1, fig. 2 and FIG. 3 shows a "Container for radionuclide sources" containing a protective container 1 and a protective container 2. The protective container 1 contains a body 3, consisting of narrow 4 and wide side sheets 5, closed by cover 6 and fixed with a locking plate 7. The side edges of the cover 6 are rectangular ledge to exclude the effect of "lumbago", described in the book of Kozlov F.V. "Handbook on radiation safety" [4]. The locking plate 7 contains a lifting element 8. The body 3 and the covers 6 are connected by hinges 9. The covers 6 and the locking plate 7 are connected by hinges 10. The locking plate 7 is fixed on the body 3 with latches 11. The body 3 is equipped with lifting elements 12. The protective container 2 contains the body 13 , made in the form of an octagonal prism, flange 14, posts 15, frame 16, wide 17 and narrow side sheets 18, bottom 19 with damping elements 20. Security container 2 is equipped with rigging elements 21 located on the narrow edges of the body 13. Top of the security container 2 closed with a removable cover 22, made in the shape of the housing 2 and mated with it by means of concentrically located fasteners.

The container for radionuclide sources works as follows. First, the locking plate 7 is opened, which is fixed on the body 3 with the help of latches 11. Then the cover 6 is opened, after which solid radioactive waste is loaded, for example, blocks of reactor graphite into the body 3 of the protective container 1. After that, the main part of the cover 6 is remotely closed using a cable fixed to the rigging element 8. The locking plate 7 is fixed on the body 3 with latches 11. The protective container 1 is installed in the body 13 of the security container 2 using the lifting elements 12. The top of the security container 2 is closed with a removable cover 22.

Thus, the container for radionuclide sources has a wide field of application, a simplified design, and can be used in nuclear technology, namely, in a system for transporting solid radioactive waste.
