Description

RADIOACTIVE BURNER CONTAINER

The utility model relates to the field of nuclear technology, and T1menually gives for waste and transportation of waste materials and can be used for long-term fanning of solid and solidified LIQUID waste, radioactive waste, in this part, includes general waste metal: , it’s good, it’s only 30 seconds long as well as hardened (including iviaiijwjj, IO cement,, polymers) sewn, worked out ft-shtomatatepiiajHii, ic iSoBbK residues.

According to C5, ni; and in accordance with the current rules, the fanning of radioactive waste must be carried out in extractable form for oeecnefjeHiM to further re-bind them. To this end, the waste will interfere in small containers or iron containers. Since KOHTemq bi from carbon steel are susceptible to Kopposiiti and do not survive prolonged fanning, and containers of high-grade stainless steel have become quite expensive, the distribution of waste containers is not too high. hermepsirovagga To ensure the rq MenwHocin ioyuzuyut razrytk tyutnenpya: rubber, shshstgzhovyu and other.

with noGJiQuj / BDUuiM it cools down after installing the roof, for which purpose the cooling pipes are installed / installed. All of these are significant costs and labor.

The smallest analogue is zhezzobeggony E1 container 2 for the disposal of solid radioactive waste, which contains a housing, the upper part of which is made with a recess, tight roof and rigging nodes located on the housing. The baffle plate and the side walls of the shell hardening have knitted shifts displaced by the bobbin relative to C) yg of the friend, and the gap between the bunkers and the vni is filled to fill the binder with the expanding material rqjMeTHsnpyionpiM. The stecha and lids are made of a thick, non-MOiee 200 mm, while it is made in the form of pflelepepea with rounded aphids.

No drawback of the closest anasch is the lack of tightness and strength of the container. Insufficient hermeticity and strength are due to the presence of the airspace of the large container and the solid framing enclosures. In the method, there is also no quality control of filling the gap rq ie TIZZ with HOT material. In addition to the design features, a low value of the ratio of the useful volume of the container to its full - OD - 0.4 can also be attributed to non-chondonal; Using the volume of radioactive radioactive substances. For a container of this type with an edge length of 1 m and a total volume of 1 m, the usable volume is less than 0.2 m, for a container with an edge length of 1.5 m and a full volume with 3.4, the usable volume is less than 1.3 m.

The usefulness of the utility model is that there is krepiya in the contamination box for the disposal of radioactive waste containing Kopwc. , clamping elements and rigging units, it was proposed to place a closed frame between the end of the container body and the roof, and KOHTeEHq) to supply the sealing solution with tight fittings and allow air to exit. The orazhakzhtskaya ryma has a crowd of 3-50 mm and can cover the coupling elements. The coupling elements of the hitch are also outside the enclosing frame. In the reinforced concrete container, the elongated elements are attached by HenoqjeacmeHHO to the ends of the walls, and in the metagal through flanges

This configuration of KonieftHqja allows you to completely fill the internal space with a self-hardening herme-adhesive solution and to control the completeness of the output of the inducted rq3MeTii3Hpyroni; ero j ciBopa elimination of gaps and cracks in the joints: sealing solution and radioactive waste; Sealant solution and porcini sealant solution and container wall, pressure-sensitive solution and enclosing frame. HarHeraeNfi M plays the role of a tidy gfmetiziruyayusche element and the internal cavity caMooTBq is waiting for a solution, and the closed opening protects the filling space and provides the necessary gap between the element of the container, since there is only one container with an open container solution. The maximum width value of the frame - 50 was chosen for the desired MOUUU - 3 DAY if3 the need for rational use of the internal volume of KOHieiiHq a and saving of applied construction materials.

With the lid removed, put in the container i-Lm-r oTBq the main drive, Hanpi-Mq cement Koismaxwi, biTyNfflbM KOisma TCl and other, install the lid and tighten the clamping elements. Then, after the shutter is closed, self-releasing, unpacking, gummetis thin solution is pumped. The filling control is carried out through leaks in the screed: after 1 2-3 test nipples, after 2–3 CVTOK of the necessary for solidification rq MenisHp iero rinse Koi-rreMnq can be absorbed into the waste bin and stored for a long time.

The presented design of the container container can be resolved in industrial conditions using a simple, widely used domestic equipment. It allows to ensure reliable gas tightness and increase the sensitivity of waste management. Increasing the EIA ratio of a useful and full o6bevia container makes it possible to use the volume of storages with active waste from the waste with a maximal effect.
