List of nuclear power accidents by country
Date Location Description Fatalities Cost ( in millions 2006 US $ )
1957 Mayak reprocessing plant , Ural-region Kyshtym disaster : Explosion in a waste tank of the plant with a massive radioactive cloud , deteriorating deeply the health of the regions population The accident caused nearly 200 late cancer fatalities ?
1975 Leningrad , Soviet union Reactor 1 of the Leningrad Nuclear Power Plant suffered a core damage which released radioactivity 0 ?
1992 Saint Petersburg , Russian Federation An RBMK reactor of the Leningrad NPP released radioactivity which traveled over north-eastern Europe . Russian officials declared that they saw no immediate danger posed by the event 0 ?
1997 Saint Petersburg , Russian Federation Worker Sergei Kharitonov revealed photographs of cracked walls and groundwater seepage at a nuclear power plant waste storage facility . He also revealed that the plant has been dumping 300 litres of contaminated water into the Gulf of Finland annually for years 0 N/A
April 1998 Saint Petersburg , Russian Federation An RBMK reactor was shut down following the discovery of a radiation leak
Autumn 2017 Ural-region , Russian Federation Roshydromet had issued report stated rise in beta activity of aerosoles and surfaces at all monitoring posts in South Ural from 25th Sep to 1 Oct 2017 . In two aerosol samples Ru-106 activity increase was detected . At 26th and 27th Sep Ru-106 decay products was detected in Tatarstan republic . At 27th and 28th Sep high pollution levels of aerosoles and surfaces was detected in Volgograd and Rostov-on-Don . In two aerosol samples from Chelyabinsk Oblast 986- and 440-fold activity increase was measured comparing to preceding month The Mayak nuclear plant is widely suspected as the source of the radiation
August 2019 Arkhangelsk region On August 9 , 2019 , the an explosion triggered radiation levels to rise near Nyonoksa , which was later confirmed by Russia 's nuclear energy agency as an accident while testing an isotope power source for a liquid-fuelled rocket engine . Five nuclear scientists had died and three suffered from burns . Russian authorities ordered the evacuation of the village nearing the blast site , suggesting grave dangers due to nuclear radiation 5

Worldwide, many nuclear accidents have occurred since the Chernobyl disaster in 1986. Two thirds of these mishaps occurred in the US. The French Atomic Energy Commission (CEA) has concluded that technical innovation cannot eliminate the risk of human errors in nuclear plant operation.
