==History==
The city is one of the newer urban centers in Dagestan. It began in 1932 as a worker's encampment, servicing the needs of the nearby naval diesel engine manufacturer, {{illm|Dagdizel|ru|Дагдизель (завод)}}. At the time, it was called ''Dvigatelstroy'' ({{lang|ru|Дви́гательстро́й}}), based upon the Russian word for "engine". During World War II, the site saw much growth due to the war effort, and became a center for major arms producers. In 1947, the settlement received the status of a city, and was given its current name, reflecting its location on the shores of the Caspian Sea.

[[File:Satellite image map of Mayak.jpg|thumb|250px|Satellite image/map of the Mayak nuclear facility.]]
The '''Mayak Production Association''' (Russian: Производственное объединение «Маяк», from Маяк 'lighthouse') is one of the biggest nuclear facilities in the Russian Federation, housing plutonium production reactors and a reprocessing plant. The nuclear complex is located 150 km south-east of [[Ekaterinburg]], between the towns of [[Kasli]] and [[Tatysh]], and 72 km northwest of [[Chelyabinsk]]. The closest city, [[Ozyorsk]], is the central administrative territorial district. As part of the Russian (formerly Soviet) nuclear weapons program, Mayak was formerly known as Chelyabinsk-40 and later as Chelyabinsk-65, referring to the postal codes of the site.<ref name=Standring>{{cite journal| url=http://www.nrpa.no/dav/1fbb52ea04.pdf | title=Review of the current status and operations at Mayak Production Association | publisher=[[Norwegian Nuclear Energy Safety Authority|Norwegian Radiation Protection Authority]] | year = 2006 | author=Will Standring }}</ref>

In 1957 Mayak was the site of the [[Kyshtym disaster]], one of the worst nuclear accidents in history. During this catastrophe, a poorly maintained storage tank exploded, releasing 50-100 tons of [[high level waste|high-level radioactive waste.]] The resulting radioactive cloud contaminated an expansive territory of more than 750 km2 (290 sq mi) in the eastern Urals with the consequence of sickness and death from [[radiation poisoning]].[[File:Mayak-FMSF-Cetac-25.jpg|thumb|250px|Fissile Material Storage Facility (FMSF). Looking at administration building of the storage facility to include all the support facilities. Excavator is one of the pieces of construction equipment procured by the USACE.]] The Soviet regime kept this accident secret for about thirty years. The event was eventually rated at 6 on the seven-level [[International Nuclear Event Scale|INES]] scale, third in severity only to the disasters at [[Chernobyl disaster|Chernobyl]] in Ukraine and [[Fukushima Daiichi nuclear disaster|Fukushima]] in Japan.<ref name=":0" />

==Design and structure==
Mayak's nuclear facility plant covers about 90 square kilometers. The site borders Ozyorsk, in which a majority of the staff of Mayak live. Mayak, itself, was not shown on Soviet public maps. The location of the site together with the plant city was chosen to minimize the effects that harmful emissions could potentially have on populated areas. Mayak is surrounded by a ~250 km<sup>2</sup> exclusion zone. Nearby is the site of the South Urals nuclear power plant.<ref>This section copied and translated from the German Wikipedia entry for "Mayak", with some grammatical errors corrected</ref>

The Mayak plant was built between 1945–48, in a great hurry and in total secrecy as part of the [[Soviet Union]]'s [[Soviet atomic bomb project|atomic bomb project]]. Five nuclear reactors were built to make, refine, and machine plutonium for weapons. Later the plant came to specialize in reprocessing [[spent nuclear fuel]] from [[nuclear reactor]]s and plutonium from decommissioned weapons. Today the plant makes [[tritium]] and [[radioisotope]]s, not plutonium. In recent years, proposals that the plant reprocess waste from foreign nuclear reactors have given rise to controversy.

==Nuclear history==
In the early years of its operation, the Mayak plant released quantities of radioactively contaminated water into several small lakes near the plant, and into the [[Techa river]], whose waters ultimately flow into the [[Ob River]]. Mayak continues to dump low-level radioactive waste directly into the Techa River today. Medium level waste is discharged into the Karachay Lake. According to the data of the Department of Natural Resources in the Ural Region, in the year 2000, more than 250 million m³ of water containing thousands of curies of tritium, strontium, and cesium-137 were discharged into the Techa River. The tritium concentration, alone, in the Techa River near the village Muslyumovo exceeds the permissible limit by 30 times.<ref name=":0">{{Cite web|url=http://www.nuclear-heritage.net/index.php/Kyshtym_Disaster|title=Kyshtym Disaster|date=6 January 2014|website=Nuclear-Heritage.net|publisher=|accessdate=25 October 2014}}</ref>

Rosatom, a state-owned nuclear operations corporation, began to resettle residents of Muslyumovo in 2006. However, only half of the residents of the village were moved. <ref name=":0" /> People continue to live in the immediate area of the plant, including [[Ozyorsk, Chelyabinsk Oblast|Ozersk]] and other downstream areas. Residents report no problems with their health and the health of Mayak plant workers. However, these claims lack hard verification, and many who worked at the plant in 1950s and 1960s subsequently died from the effects of radiation.<ref>{{cite journal |last1=Koshurnikova |first1=N.A. |last2=Shilnikova |first2=N.S. |last3=Sokolnikov |first3=M.E. |last4=Bolotnikova |first4=M.G. |last5=Okatenko |first5=P.V. |last6=Kuznetsova |first6=I.S. |last7=Vasilenko |first7=E.K. |last8=Khokhryakov |first8=V.F. |last9=Kreslov |first9=V.V. |title= Medical-dosimetry registry of workers at the 'Mayak' production association |journal=International Journal of Low Radiation |year=2006 |volume=2 |issue=3/4 |pages=236–242|publisher=Inderscience Publishers |doi=10.1504/IJLR.2006.009516 |url=http://www.inderscience.com/search/index.php?action=record&rec_id=9516&prevQuery=&ps=10&m=or |accessdate=6/01/2012 }}</ref><ref>{{cite journal |last1=Azizova |first1=Tamara V. |last2=Muirhead |first2= Colin R. |last3= Moseeva |first3= Maria B. |last4=Grigoryeva |first4=Evgenia S. |last5=Sumina |first5= Margarita V. |last6=O’Hagan |first6=Jacqueline |last7= Zhang |first7=Wei |last8=Haylock |first8= Richard J.

When [[Zhores Medvedev]] exposed the disaster in a 1976 article in the New Scientist, some exaggerated claims circulated in the absence of any verifiable information from the Soviet Union. People "grew hysterical with fear with the incidence of unknown 'mysterious' diseases breaking out. Victims were seen with skin 'sloughing off' their faces, hands and other exposed parts of their bodies."<ref name="p">Pollock, Richard, 1978. "Soviets Experience Nuclear Accident," ''Critical Mass Journal 3'' pp.7–8</ref> "Hundreds of square miles were left barren and unusable for decades and maybe centuries. Hundreds of people died, thousands were injured and surrounding areas were evacuated."<ref>[[Zhores Medvedev]], ''The Australian'', 9.12.1976</ref> Professor Leo Tumerman, former head of the Biophysics Laboratory at the Institute of Molecular Biology in Moscow, disclosed what he knew of the accident around the same time. Russian documents gradually declassified from 1989 onward show the true events were less severe than rumored.

According to Gyorgy,<ref>Gyorgy, A. et al., 1980. [https://books.google.com/books?id=YKP_KZGD7dwC&pg=PA13 ''No Nukes: Everyone's Guide to Nuclear Power''].

"[[Ralph Nader]] surmised that the information had not been released because of the reluctance of the CIA to highlight a nuclear accident in the USSR, that could cause concern among people living near nuclear facilities in the USA."<ref name=p/> Only in 1992, shortly after the fall of the USSR, did the Russians officially acknowledge the accident.

==Other accidents==
[[File:Mayak-FMSF-Cetac-37.jpg|thumb|250px|Fissile Material Storage Facility (FMSF). The building is the ventilation center of the storage facility. The ventilation tunnel showing in the north of the ventilation center.]]
In December 1968, the facility was experimenting with plutonium purification techniques. Two operators were using an "unfavorable geometry vessel in an improvised and unapproved operation as a temporary vessel for storing plutonium organic solution."<ref name=McLaughlin>McLaughlin et al. "[http://www.orau.org/ptp/Library/accidents/la-13638.pdf A Review of Criticality Accidents]" by Los Alamos National Laboratory (Report LA-13638), May 2000</ref> "Unfavorable geometry" means that the vessel was too compact, reducing the amount of plutonium needed to achieve a critical mass to less than the amount present. After most of the solution had been poured out, there was a flash of light and heat. After the complex had been evacuated, the shift supervisor and radiation control supervisor re-entered the building. The shift supervisor then entered the room of the incident, caused another, larger nuclear reaction and irradiated himself with a deadly dose of radiation.<ref>[http://darwinawards.com/darwin/darwin1994-25.html Glowing Georji]: A 1994 [[Darwin Award]] nominee</ref>

The Mayak plant is associated with two other major nuclear accidents. The first occurred as a result of heavy rains causing [[Lake Karachay]], a dried-up radioactively polluted lake (used as a dumping basin for Mayak's radioactive waste since 1951), to release radioactive material into surrounding waters. The second occurred in 1967 when wind spread dust from the bottom of [[Lake Karachay]] over parts of [[Ozyorsk, Chelyabinsk Oblast|Ozersk]]; over 400,000 people were irradiated{{quantify|date=October 2016}}.<ref name=am>[http://www1.american.edu/projects/mandala/TED/ural.htm A report on the 1957 accident and on endemic radioactive pollution at Mayak]</ref>{{better source|date=October 2016}}

* 15/03/1953 - [[Criticality accident]]. Contamination of plant personnel occurred.
* 13/10/1955 - Rupture of process equipment and the destruction of a process building.
* 21/04/1957 - Criticality accident. One operator died from receiving over 3000 rad. Five others received doses of 300 to 1,000 rem and temporarily became sick with radiation poisoning.
* 10/02/1958 - Criticality accident in SCR plant. Plant workers conducted experiments to determine the critical mass of enriched uranium in a cylindrical container with different concentrations of uranium in solution. Personnel received doses from 7600 to 13,000 rem, resulting in three deaths and one case of blindness caused by radiation sickness.
* 12/05/1960 - Criticality accident. Five people were contaminated.
* 26/02/1962 - Destruction of equipment. An explosion occurred in the absorption column.
* 09/07/1962 - Criticality accident.
* 16/12/1965 - Criticality accident. Seventeen individuals received exposure to small amounts of radiation over a period of 14 hours.
* 10/12/1968 - Criticality accident. Plutonium solution was poured into a cylindrical container with dangerous geometry. One person died, another took a high dose of radiation and radiation sickness, after which he had both legs and his right arm amputated.
* 11/02/1976 - Unsafe actions of staff development at the radiochemical plant caused an autocatalytic reaction of concentrated nitric acid and organic liquid complex composition. The device exploded, contaminating the repair zone and areas around the plant. The incident merited a [[International Nuclear Event Scale]] rating of 3.
* 10/02/1984 - Explosion.
* 16/11/1990 - Explosion. Two people received burns and one was killed.
* 07/17/1993 - Accident at radioisotope plant, resulting in the destruction of the absorption column and release into the environment of a small amount of α-aerosols. Radiation emission was localized at the manufacturing facility of the shop.
* 08/02/1993 - Depressurization of a pipeline caused 2 m^3 of radioactive slurry (about 100 m^2 of contaminated surface) to leak to the surface of the pulp radioactive activity of about 0.3 Ci. Radioactive trace was localized, contaminated soil removed.
* 12/27/1993 - Incident at radioisotope plant where the replacement of a filter resulted in the release into the atmosphere of radioactive aerosols. Emissions were on the α-activity of 0.033 Ci, and β-activity of 0.36 mCi.
* 04/02/1994 - Recorded increased release of radioactive aerosols: the β-activity of 2-day levels of Cs-137 subsistence levels, the total activity of 7.15 mCi.
* 30/03/1994 - Recorded excess daily release of Cs-137 in 3, β-activity - 1,7, α-activity - by 1.9 times. In May 1994 the ventilation system of the building of the plant spewed activity 10.4 mCi β-aerosols. Emission of Cs-137 was 83% of the control level.
* 07/07/1994 - The control plant detected a radioactive spot area of several square decimeters. Exposure dose was 500 millirems per second. The spot was formed by leaking sewage.
* 31/08/1994 - Registered an increased release of radionuclides to the atmospheric pipe building reprocessing plant (238.8 mCi, with the share of Cs-137 was 4.36% of the annual emission limit of this radionuclide). The reason for the release of radionuclides was depressurization of VVER-440 fuel elements during the operation segments idle all SFA (spent fuel assemblies) as a result of an uncontrollable arc.
* 24/03/1995 - Recorded excess of 19% of normal loading apparatus plutonium, which can be regarded as a dangerous nuclear incident.
* 15/09/1995 - High-level liquid radioactive waste (LRW) was found in flow of cooling water. Operation of a furnace into the regulatory regime has been discontinued.
* 21/12/1995 - Cutting of a thermometric channel exposed four workers (1.69, 0.59, 0.45, 0.34 rem) when operators violated process procedures.
* 24/07/1995 - Cs-137 aerosols released, the value of which amounted to 0.27% of the annual value of MPE for the enterprise.
* 14/09/1995 - Replacement covers and lubrication step manipulators registered a sharp increase in airborne α-nuclides.
* 22/10/1996 - Depressurization occurred in a coil while channeling cooling water from one storage tanks of high-level waste. The result was contaminated pipe cooling system repositories. As a result of this incident, 10 people were exposed to radiation dose of 2.23 to 48 milli-[[Sievert]]s.
* 20/11/1996 - A chemical-metallurgical plant in the works on the electrical exhaust fan caused aerosol release of radionuclides into the atmosphere, which made up 10% of the allowed annual emissions of the plant.
* 27/08/1997 - In building RT-1 in one of the rooms was found to be contaminated floor area of 1 to 2 m 2, the dose rate of gamma radiation from the spot was between 40 and 200 mR / s.
* 06/10/1997 - Recorded increasing radioactivity in the assembly building, the RT-1. Measurement of the exposure dose indicated up to 300 mR / s.
* 23/09/1998 - While increasing power output of reactor P-2 ("Lyudmila") after engaging automatic protection allowable power level was exceeded by 10%. As a result, the three channels of the fuel rod seal failed, resulting in the contamination of equipment and pipelines of the first circuit.<ref>All of the above list transferred directly from the Russian Wikipedia entry for "Mayak".

More recent major accidents:

* In 2003, the plant's operating licence was revoked temporarily due to liquid radioactive waste handling procedures resulting in waste being disposed into open water.<ref>http://www.bellona.org/english_import_area/international/russia/nuke_industry/siberia/mayak/27922</ref>
* In June 2007, an accident involving a radioactive pulp occurred over a two-day period.<ref name="bellona.org">http://www.bellona.org/articles/articles_2007/Mayak_leak</ref>
* In October 2007, a valve failure during transport of a radioactive liquid resulted in spilling of a radioactive material.<ref name="bellona.org"/>
* In 2008, a repair worker was injured during a "pneumatic" incident, involving a quantity of alpha emitter release. The worker's hand was injured and the wound contaminated, with the worker's finger amputated to avoid further injury.<ref>http://www.bellona.org/articles/articles_2008/another_mayak_incident</ref>
