The invention relates to an apparatus for storage in the sea of hazardous wastes, especially low-level radioactive waste.

Worldwide there is a huge and cranie "hazardous waste" means dangerously contaminated, infectious or other hazardous materials, i.e. materials with which you want to apply and store them so that they were properly insulated. For example, if large quantities of waste are temporarily stored in drums or other containers that are exposed to corrosion and have no leaks, then you can assume that they will begin to leak in the next few years.

Radioactive waste is a vivid example of hazardous waste, apparently, are exactly the type of hazardous waste, for which, at least at the present time, the most strongly required to develop a storage system that provides adequate security and can be created of sufficient capacity.

The present invention is the creation of a system for temporary or permanent storage of hazardous waste, in particular radioactive hazardous waste, and more specifically low level waste, which can be characterized as hazardous waste and low or medium risk.

Such hazardous wastes exist in many forms, such as, for example:

- soil, sand, water (reactor water);

- samples of different objects is Sobranie on part or section of the reactor, for example);

- barrels or other containers containing radioactive material.

From these examples it is obvious that the forms of hazardous waste, which are considered here can also include highly dangerous radioactive material, as, for example, the fuel rods enclosed in protective boxes, or other inclusions, such that, when they will be closed, you can treat them as hazardous waste with a low or moderate activity at least for a limited time shorter than the time of final storage.

The prior art related to storage in the sea of hazardous waste, illustrated W091/05351. This publication describes the installation for the storage of hazardous waste, comprising a housing for storing in the form of a ring-shaped concrete structure, adapted to rest in submerged at the bottom of the sea, and are equipped with multiple open top spaces for storage, each of which is adapted for placing concrete storage container, which in turn are enclosed hazardous waste.

In the storage facility prior art, separate containers for XP is needful protection of the structure from a prisoner in their material, for example, protection against access and protection from radioactivity.

Furthermore, in installations of the prior art separate storage containers adapted to after loading hazardous waste and seals to transport them as a floating body, for example, to the housing for storage, where they are dipped into the case for storage. The lowering is carried out by a regulated supply of water in ballast tanks that are empty during transportation on the water surface.

Install in accordance with the present invention, the characteristic features of which are set out in the claims, has some characteristics in common with the installation of the prior art, but differs from it essentially.

Thus, the installation of prior art storage case for represents the first fully immersed in a sea of land for storage of containers, which themselves are essentially provide protection design. Accordingly, the additional protection provided by enclosure for storage, mainly remains within the housing for storage.

On the other hand, in accordance with the invention, complete protection (or pousa for storage in the marine areas.

Moreover, the storage facility in accordance with the invention includes a housing terminal that receives hazardous waste from, for example, water or air vehicles, primarily vessels and from which hazardous waste is moved into the main body through the use of vehicles that are part of the installation, such as conveyors or trucks.

The invention will be further explained through the following description of the example storage facilities in accordance with the invention. The installation illustrated in the accompanying schematic drawings.

Fig. 3A is an enlarged section along the line IIIA-IIIA of Fig. 3 part of the main body;

Fig. 4 is a vertical section along the line IV-IV of Fig. 1.

As shown in the drawings, the apparatus comprises a body terminal 10 and several buildings for storage, hereinafter referred to as the base of the case and indicated by callout 11, which are located near the terminal housing and the side by side against one the next base, which previously had been prepared on the bottom of the sea. The neighbouring building are linked, for example, through the connecting ropes, thus, the unit forms a coherent whole.

The upper side of the terminal housing 10 or at least part of the upper side is located above the sea level. It can also refer to the main chassis 11, however, these housing or at least some of them may have a top side, lying below sea level.

On the main chassis 11, or at least some of them provided by the storage tanks of the type of bins, in which at least the upper part are located entirely above sea level.

The body of the terminal 10 and the main body 11 are the main components of the installation, and the main body may include storage tanks, if they are provided.

The body of the terminal 10 is a unit designed to perform various support functions, such as receiving incoming materials, which must be placed in storage, shipment of materials in storage to remove them from the installation, storage of consumable products, placement workshop, dstanley a blocks valid for storage of hazardous materials, to denote which then often uses the term "materials stored".

Storage can be the final storage of low level waste (for example, for a period of 50 years), or temporary storage pending exportation of materials stored on site final storage.

The definition of "temporary" is used in this context, means that storage can be both shorter and longer term, for example, a few years or a few decades.

Materials arriving at the store, are transported from the terminal housing 10 to the space for storage in the main chassis 11. For the purpose of this transportation is provided by connection paths that connect to the body of the terminal and storage space in the main hull. These connection paths can be formed elongated sections 14, which are inserted between adjacent main buildings 11 and outline the transport path, on which the movement of the cars, the track, which rely on associated with the rails cars, trains or the like, the conveyors of various types and what to find.

In Fig. 1 and 2 of section 14, defining the major connective paths are arranged so that they connect all of the main housing 11 with the terminal housing 10. With these main sections of the connecting path 14 to a separate space to store S in the main chassis 11 can be implemented approach through the side passages. The arrows L in Fig. 2 shows a similar approach to space for storage S.

As is evident from Fig. 1, the storage facility in accordance with the invention can be quickly expanded to increase the storage capacity by adding a large number of main body 11. If required, can also be added one or more additional buildings of the terminal 10.

Preferably the main body 11 are as solid concrete blocks having dimensions horizontally (length, width), for example, 200 x 200 meters. They can be manufactured using the technology of concrete by the slipform method, which is suitable for offshore installations, which may be constructed in accordance with the principles described in U.S. patent N 3,249,664, 3,686,886 and 4,556,002.

Separate the main body 11 can be characterized simply as pramool Jindrisska parallel storage compartments S, run along the entire length of the main body from one side to the opposite side, the upper part 11B and the lower portion 11C having a similar, but smaller offices, K.

The thickness or height of the concrete slab is determined by the number of tiers of storage compartments S, the height of each tier and the heights of the upper section and the lower section and can have a value of about 100 m for the above values of the width and length.

After the concrete slab will produce in a standing position with storage compartments, passing in the vertical direction, and upside-down in a horizontal position in which it floats in water, by moving ballast (water) in spaces used as tanks for ballast, it can be provided with the previously mentioned tanks 12 on its upper side; it can also be produced using the technology of concrete method of the sliding formwork. In the design shown on the right side in Fig. 1 and 2, the tank 12 includes an inner tank 12A and the outer tank 12B concentric with him. These tanks 12A and 12B are intended for storage of bulk materials, such as radioactive water into the internal reservati combined with means for detecting leakage of the material and return it to the tank or pass it into the space inside the main body 11, provided for the collection of such material. These spaces can be, for example, some of the branches of K or other open spaces between departments or between departments S in the middle part 11A of the main body.

Finished the main body 11 with the tank 12, or without it, and provided with means for sealing the compartments S and K (these means, not shown, may be partially permanently sealed and partially can be opened) is transported by the water on the prepared Foundation or base on the bottom of the sea where it sinks designed for it and is connected with the terminal housing or other main buildings.

Accordingly, the monolithic main body 11 is made as a shell design, and an example of such design is shown in Fig. 3A in an enlarged scale, in this case the separation S in the middle part 11A limited to the inner wall of the double-layer cylindrical shell structure, the outer wall of which is connected with the inner wall of the through ribs. The space between the walls of the shell can be used to collect leakage of material from the tank 12 or branches S and provide access to 12 is an optional part of the main body in accordance with the invention. Materials stored, those kinds of placement, which is the reservoir 12 can, of course, also be stored in the offices of S and K of the main body 11.

The body of the terminal 10 also includes a dock 15 with attached piers and loading and unloading means (not shown) through which the material received at the storage can be unloaded with water vehicles, such as ships or barges. After unloading the materials received for storage, can be transported into the intended storage compartment S in one of the main body 11 by means of a ramp or other connection with the transport sections 14. Transportation can also be done using trucks or open platforms.

Moreover, the body of the terminal 10 includes a discharge installation 16 for receiving bulk materials going into storage, such as radioactive soil or radioactive water. This installation includes dock for barges or a vessel with a hinged bottom P formed in the pivoting hole which can be connected with the shaft 17, which is received at the storage material unloaded from a barge or vessel, are removed in resarea terminal 10, which in Fig. 1 separated from the dock 15 and unloading installation 16 through lying between the transport section 14, is used as a dwelling, workshop, administrative and management areas. During manufacture the main body of the terminal can also be used as a concrete plant, and as a platform for the reception of all incoming materials used for manufacturing the main buildings.

All admission materials for storage or shipment should not take place in the terminal housing. The design of the main body 11 in accordance with the invention makes it possible and convenient reception of certain types of materials entering the storage of water directly through one end of the one or more storage compartments S, and to this end, these offices are equipped with opening gates (not shown). Thus, submarines entirely, if necessary without towers, or at least part of submarines containing nuclear reactors, can be taken directly from the water. This method of reception of materials graphically indicated by the arrow U in Fig. 2.
