The burial place of Radioactive Waste «Buryakovka»

The burial site of Radioactive Waste "Buryakovka"

is a trench-area type burial ground. In about 30 clay-earthen trenches the burial ground was disposed of the incombustible solid waste of 1 and 2 pollution groups, such as soil, rubble, construction debris, scrap metal, building structures, etc.
In May-June 1986, the liquidators faced an acute shortage of sites for the reliable burial of contaminated soil collected at the NPP site, the remains of the destroyed building structures of Unit 4 and other medium-level waste.

Therefore, employees of VNIPIET Kurchatov and related institutes carried out the selection work on the site for the arrangement of a near-surface burial ground. As a result of the geological survey, a site was chosen between the villages of Buryakovka and Styachanka on the Lelevsko-Chistogalovsky clay ridge, approved by the Chairman of the Government Commission on June 23, 1986, and commissioned in February 1987. The construction of the graveyard was carried out strictly in accordance with SPORO-85 sanitary rules for the management of radioactive waste), its estimated service life is 300 years. In addition to the modules (tranches) for medium-level radioactive waste in the Buryakovka PZRO, there is a concrete site for the burial of metal structures and equipment, on which the equipment is built in rows. In the same way, it is built at the now liquidated "Rassokha" sump.

According to the initial design, the trench capacity should have been 15,000 m³, later the project was adjusted to increase capacity to 25,000 m³. Today, the RWR is a rectangular platform with sides 1200 x 700 m, 30 modules (trenches) are placed on it: dimensions 155 m, width 88 m, depth 9.7 m. A clay layer 1 m thick was placed on the bottom of the trench, on the sides and top with a thickness of 0.5 m to protect the screen from damage during the filling of the module, it was additionally covered on all sides with a layer of sand 1 m thick. In order to prevent precipitation from entering the module, a sand cushion was placed on top of the screen, which was covered with a 20 cm layer of turf. 

According to the Government Commission Regulation repository received solid waste activity to 5 R / h. Waste was transported and stored in trenches on special vehicles KRAZ-256, with a shielded cab and a dump body covered with a layer of steel that could be easily decontaminated. The special attention was paid to preventing the contact of radioactive waste with the wheels of the car, after filling a layer of 1.5 m thick, the waste was leveled with a specially prepared heavy bulldozer T-330. During the works, the working space was constantly moistened to suppress dust formation, an absorbent layer of clay 0.2 m thick was laid between the layers of RAW, and so until the trench was fully filled. According to SPORO-85 standards, administrative control over completed and canned modules should be carried out for 30 years, and sanitary supervision for 300 years. After filling and preservation of the storage, the conditions of the environment including DER levels, specific air activity, surface contamination of the soil with radionuclides, are constantly monitored. 

10 years of operation of the graveyard had resulted in its full loading.  Therefore, on April 29, 1996, a decision was made to reconstruct the Buryakovka BWR. The reconstruction meant the expansion of production volumes for the disposal of waste. According to the project, six new surface modules with a total volume of about 12,000 m³ were built and located in the space between the filled trenches with radioactive waste.

On the territory of the PZRO, there is a repository of metal radwaste - site No. 13. A specially constructed concrete slab has a system for removing precipitation from the surface, to reduce the evaporation area, as well as a system for filtering the atmospheric precipitation from the site. In contrary to the sedimentation tank "Rassokha" where the technique was supposed to withstand the acceptable values of infection and be reused, the reuse of equipment from the graveyard was not planned. In addition to the army and civilian equipment, contaminated equipment and mechanisms from the site of the station are stored on the territory of the graveyard. Infected equipment from the Chernobyl nuclear power plant was buried at the PODRO "Podlesny" in specially constructed concrete storage facilities, and the equipment used for the construction of the Shelter, decontamination of the industrial site and part of the equipment from the engine room of the third stage of the construction of the Chernobyl NPP, is located in the open air at site No. 13.
It stores almost all the samples of equipment that took part in the elimination of the consequences of the accident, especially the remains of robotics of the cleaned roof of the Chernobyl NPP and worked in radiation fields with a capacity of up to 12,000 R / h. 
Army engineering equipment in the form of machines IMR, BAT-2 and BREM collecting high-level radioactive waste directly under the walls of the 4th power unit that buried the Red Forest, villages near the station and ground within a radius of 2 km from the nuclear power plant. Helicopters involved in radiation exploration - rare Mi-24R (item 2462) and giants Mi-6, the so-called "bardoliers" spraying over the Zone a special mixture of "bordeaux" for binding radionuclides. Specially built for the needs of the liquidators, dust suppressors based on heavy-duty dump trucks BelAZ, heavy tractor trucks MAZ-537 carrying armored vehicles and containers with highly active radioactive waste, armored vehicles for radiation reconnaissance of BRDM-RHB, as well as numerous special communication vehicles, trucks and other equipment of liquidators.
