A history of chernobyl disaster

Chernobyl Chernobyl, or Chornobyl, is the name of a city situated in northern Ukraine near the border with Belarus. Chernobyl was largely abandoned following the disaster at the Chernobyl Nuclear Power Plant located Prior to its evacuation Chernobyl was inhabited by 16, people but is now populated only by Zone administrative personnel, some of those involved in decommissioning the power plants and a number of residents who refused to leave their homes or subsequently returned.

What is the Chernobyl Disaster? An explosion and fire released large quantities of radioactive contamination into the atmosphere, which spread over much of Western USSR and Europe. It is considered the worst nuclear power plant accident in history and is one of only two classified as a level 7 event on the International Nuclear Event Scale the other being the Fukushima nuclear disaster in Aerial view of Reactor Four The disaster began during a systems test at reactor number four of the Chernobyl plant.

There was a sudden surge of power output, and when an emergency shutdown was attempted a more extreme spike in power output occurred, which led a reactor vessel to rupture and a series of explosions.

These events exposed the graphite moderator of the reactor to air, causing it to ignite. The resulting fire sent a plume of highly radioactive smoke into the atmosphere and over an extensive geographical area. The plume went on to drift over large parts of the western Soviet Union and Europe.

Only after the level of radiation set off alarms at the Forsmark Nuclear Power Plant in Sweden, over one thousand kilometers from the Chernobyl Plant, did the Soviet Union publicly admit that an accident had occurred.

The true scale of the disaster was concealed. After evacuating the nearby city of Pripyat, the following warning message was read on state TV: One of the nuclear reactors was damaged. The effects of the accident are being remedied.

Assistance has been provided to any affected people. An investigative commission has been set up. Thirty one deaths are directly attributed to the accident, all among the reactor staff and emergency workers.

Estimates of the number of deaths potentially resulting from the accident vary enormously. The World Health Organization WHO suggests it could reach 4, civilian deaths, a figure which does not include military clean-up worker casualties.

A report predicted 30, to 60, cancer deaths as a result of Chernobyl fallout. A Greenpeace report puts this figure ator more. The Russian publication, Chernobyl, concludes thatpremature cancer deaths occurred worldwide between and as a result of radioactive contamination from Chernobyl.

Nearly 5 million people including, more than 1 million children still live with dangerous levels of radioactive contamination in Belarus, Ukraine, and European Russia. Consequences of the Catastrophe for People and the Environment PDF; 4,3 MB A massive concrete and metal structure, a sarcophaguswas hastily constructed to encase Unit 4 as an emergency measure to halt the release of radiation into the atmosphere following the disaster.

What is the Exclusion Zone? Established soon after the disaster by the Russian military to cover the areas worst affected by radioactive contamination it was initially an area of 30 kilometer 19 mile radius from the Chernobyl Nuclear Power Plant designated for evacuation and placed under military control.

Its borders have since been expanded to cover a larger area of the territory of Ukraine, approximately 2, km2.

The purpose of the Exclusion Zone is to restrict access to the most hazardous areas, reduce the spread of radiological contamination and conduct radiological and ecological monitoring activities. Today, the Exclusion Zone is one of the most radioactively contaminated areas in the world and draws significant scientific interest due to the high levels of radiation exposure in the environment, as well as an increasing interest from tourists.The accident at the Chernobyl nuclear power plant in Ukraine has been described as the worst nuclear disaster the world has ever seen.

Chernobyl disaster: Chernobyl disaster, an accident at the Chernobyl nuclear power station in the Soviet Union in , the worst disaster in nuclear power generation history. Between 2 and 50 people were killed in the initial explosions, and dozens more contracted serious radiation sickness, some .

Today marks the anniversary of the Chernobyl nuclear disaster. On April 26, , technicians conducting a test inadvertently caused the fourth reactor to explode.

Citation Information

The Chernobyl disaster was a unique event and the only accident in the history of commercial nuclear power where radiation-related fatalities occurred e. The design of the reactor is unique and in that respect the accident is thus of little relevance to the rest of the nuclear industry outside the then Eastern Bloc.

Chernobyl. Chernobyl, or Chornobyl, is the name of a city situated in northern Ukraine near the border with Belarus. Chernobyl was largely abandoned following the disaster at the Chernobyl Nuclear Power Plant located kilometres (9 miles) away. The Chernobyl nuclear disaster of April 26, , is predicted to continue to harm the environment for at least years.
