Kyshtym Disaster

In 1957 a tank of liquid, highly radioactive waste left from reprocessing nuclear fuel, exploded in a region of the Soviet Union called Kyshtym in the Ural Mountains of Siberia. The accident was kept secret for several decades, but we now know that it was at a secret nuclear reprocessing site called Mayak. This accident resulted in a regional disaster and a radioactive cloud that contaminated more than 300 square miles… many people received very high radiation exposures, some suffered acute radiation syndrome. Because of secrecy in the nuclear establishment it is not clear what exactly happened but estimates are at least 200 people died of “excess” cancer and scores of villages and towns were permanently abandoned due to the sever radioactive contamination.

The Kyshtym Disaster was an accident in the world's largest nuclear complex Mayak in Russia and is today one of the most radioactively contaminated places in the world. Until Chernobyl, Mayak was the site of the worst nuclear disaster in history. Unlike Chernobyl, it has received very little attention. The Mayak nuclear facility, until recently deleted from all Russian maps, is the size of a small city and has been used to manufacture plutonium for nuclear weapons and reprocess nuclear reactor fuel for over 50 years. Since the 1950s, accidental and deliberate releases of radiation have exposed over a quarter of a million people living around the plant to high levels of radiation. Thousands have died and many more live with its debilitating legacy: sickness, sterility and poverty. Now the Russian Government is considering plans to import nuclear waste to Mayak from around the world.

Wasteland

The information in this section is extracted from the DVD "WASTELAND" by Greenworld, Sosnovy Bor Leningrad region.

The Kola NPP is located on the peninsula on the bank of Lake Imandra. There is no smoke visible from the NPP chimneys. (...) However, a price far too dear is paid for the wellbeing of the locals. Any nuclear power plant produces spent nuclear fuel and radioactive wastes which are extremely dangerous to all living things. Since the late 70-s the spent nuclear fuel from the VVER-440 reactors of the Kola NPP has been processed to produce new fuel for the RBMK reactors of the Leningrad NPP.

Alexey Yablokov, president of the Center for the Ecological Policy of Russia, Moscow:
People from North-West Russia, the Kola and Leningrad NPPs, Murmansk, from this whole region should not think that when the spent nuclear fuel is transported for re-processing elsewhere, their social responsibilities cease. Out of sight, out of mind. They all are responsible because Mayak is a highly polluting industry. It might be one of the worst offenders in polluting the environment.

The history of radiation accidents in the former Soviet Union originated in the Chelyabinsk region at the plutonium facility No 817 which is known today as the industrial enterprise "Mayak". The first nuclear reactor and radiochemical plant were built here in mid-40s of the 20th century. Here, on the southern bank of the Kiziltash lake, under conditions of total secrecy, in feverish haste burning out and wasting the workers the first Soviet atomic bomb was created. The liquid radioactive waste was discharged directly into the Techa river.

The managers of the enterprise knew that any remedial actions would have to be taken under conditions of high radiation but they silently reconciled themselves to possible victims. Actually, victims were expected. The high accident risk at nuclear facilities at that time was not so much due to complication and novelty of the process as to all pervasive urgency and disregard of human lives. Industrial equipment was seemingly much more valuable than health and the personnel lives and the dangerous impact of nuclear facilities on the environment and the residential population was not taken into consideration at all. A large number of people were involved in the accident mitigation process acting manually without even elementary means of protection.

On September 29, 1957 a liquid waste storage container exploded and released 20 MCi of radioactivity. Within 10 hours radioactive cloud spread over the Chelyabinsk, Sverdlovsk, and Tyumen regions over 23,000 km². This is usually referred as the East-Ural Radioactive Trace or the "Kyshtym disaster".

Conscript soldiers and even schoolchildren were involved in the decontamination effort of the accident area. Exposure standards were violated and maximum exposure limits were sufficiently exceeded. A lot of accident clean-up workers acquired lethal radiation doses of more than 100 Roentgen. The Kyshtym disaster is the second largest devastation after Chernobyl. After the accident 248 villages were resettled from the Techa river. The total number of officially registered casualties is more than 500,000 people not including the military personnel of the construction battalions.

After the Kyshtym disaster in 1957 the Karachay Lake on the territory of the Mayak facility was used for open-air "storage" of liquid radioactive wastes. In 1967 a strong wind raised the dangerous radioactive silt from the shallow banks of the Karachay Lake. As a result an area of approximately 1,800 km² was contaminated with radionuclides. It affected the same territory of the Eastern-Ural Radioactive Trace and again the residents of the local settlements became victims of radioactive exposure.

(...) A sadly famous village of Muslyumovo. It is located on both banks of the Techa River. There are 7 graveyards for only the four and a half thousand residents.

Gosman Kabirov, NGO "TECHA":
There is the mill of the merchant Zlokazov behind me. In 1941 a glue production factory was moved to here from Leningrad. In 1952 during strong flooding there were immediate releases of plutonium from the Mayak facility. Due to the contamination of the territory the plant was closed.

There is a similar half-ruined building nearby which housed on orphanage until the 1990-s. The children freely bathed in the river, fished and ate the fish. Later the orphanage was closed and the former pupils dispersed all over the country. No one knows their future ...

Gosman Kabirov, NGO "TECHA":
There is the highest radiation background in the village since the dam functioned until its closure in 1954. Whatever radioactive contamination that flowed was deposited here. Underneath here it shows up to 4,500 micro R/h. Old women were sitting here all day long pasturing geese. They received an annual maximum radiation dose in just one day, over and over again.
