A small percentage of accidents, explosions, “incidents”, meltdowns is reported the nuclear designed media and to the public. Reason: World’s most advanced radiation measurement network is concealed by IAEA, since Kennedy signed the CTBT: https://tekknorg.wordpress.com/2012/05/28/iaea-conceales-ctbto-fukushima-data/ and, of course, during Cold War, US and Soviet government concealed everything. Today, they nearly do the same. Look at Japan and Fukushima.
UNKOWN NUCLEAR DISASTERS:
- On 7 May 1966, an accident occurred at an experimental boiling water reactor in Melekess (near to the city Gorjkii, now Nizhni Novgorod). In case of this accident, a power excursion appeared because of chain reaction by prompt neutrons. The operator and shift foreman received high doses of irradiation.
- During 1964 – 1979, a series of destruction of fuel channels occurred in the reactor of the Unit 1 of the Beloyarsky NPP. The reactor of this NPP was of a channel-type reactor quite similar to the RBMK. These accidents caused every time a significant irradiation of the personnel.
- On 7 January 1974, an accident happened at the Unit 1 of the Leningrad NPP. In case of this accident, a ferroconcrete gasholder of the system to retain radioactive gases was destroyed. There were no victims
by this accident.
- On 6 February 1974, a rupture of the intermediate circuit of the Unit 1 of the Leningrad NPP occurred because of water boiling in it. Three persons were killed by this accident. High radioactive water together with radioactive sludge of the filter powder was discharged into the environment.
- In October 1975, a partial destruction of the core of the Unit 1 of the Leningrad NPP occurred. The reactor was shut down and the core was cleaned on the next day after the shutdown by pumping of an emergency reserve of nitrogen through the core to the ventilation chimney. Consequently, approximately 1.5 million Curie of radioactive substances was discharged into the environment: http://www.greenworld.org.ru/?q=ang_lnpp1_main
- In 1977, 50% of fuel channels were melted in the core of the Unit 2 of the Beloyarsky NPP. The reactor of this NPP was of a channel-type also quite similar to the RBMK. Repairing of the reactor was about 1 year long. The high irradiation of the personnel occurred.
- On 31 December 1978, a large fire at the Unit 2 of the Beloyarsky NPP. The fire was initiated through a downfall of a covering plate of the powerhouse hall on the turbine oil tank. 8 persons received high doses during an organization of the core emergency cooling.
- In September 1982, a fuel channel in the center of the core of the Unit 1 of the Chernobyl NPP was destroyed as a result of mistakes made by the personnel. A large amount of radioactive substances was released to the industrial site of the NPP and the city Pripyat. The personnel involved in the liquidation of the consequences of this accident received high irradiation doses. / Chernobyl had it’s first accident, it went super critical during a TEST. The same situation caused the explosions in 1986: http://guacfund.org/nss-folder/sharedpublications/NM724.pdf
- In October 1982, the generator of the Unit 1 of the Armenian NPP exploded. The hall for the turbogenerator burnt down. The main part of the personnel of the NPP simply fled from the plant leaving it in the emergency state. The special operative group of specialists from the Kolsk NPP flew by an airplane and helped to save the Armenian NPP.
- On 27 June 1985, an accident occurred at the Unit 1 of the Balakovo NPP. One secure valve of the cooling circuit was pulled out. Therefore, the water steam at the temperature 300 °C came to a room where people worked. 14 people were killed by this accident. The accident happened because of an unusual tempo of the work and because of low experience of people.
- In August 1985, a severe accident happened in the bay near Vladivostok when reloading submarine reactors. This time, a water-water type reactor exploded. 10 people were killed by the accident. The spontaneous chain reaction with a high release of energy arose. It caused a prompt evaporation of the coolant. As a result of the explosion, the core with the fresh fuel was thrown to the pier. This accident demonstrated clearly that water-water nuclear reactors can explode too.
