What is nuclear accident

A nuclear and radiation accident is defined by the International Atomic Energy Agency (IAEA) as "an event that has led to significant consequences to people, the environment or the facility." Examples include lethal effects to individuals, large radioactivity release to the environment, or reactor core melt.

International Nuclear Event Scale

Nuclear power plant accidents 1  Chernobyl disaster:- Chernobyl disaster which occurred in 1986 in Ukraine.- The accident killed 30 000 people directly and damaged

approximately $7 billion of property.- That caused  4,000 additional cancer deaths

2 Fukushima Daiichi nuclear disaster:- accident on 11 March 2011- The accident was rated 7 on scale- over 100,000 people had to be evacuated from their

homes to ensure this. 

Atomic bombings of Hiroshima and Nagasaki >The United States, with the consent of the United Kingdom as laid down in the Quebec Agreement, dropped nuclear weaponson the Japanese cities of Hiroshima and Nagasaki in August 1945, during the final stage of the World War II. The two bombings, which killed at least 1,29,000 people, remain the only use of nuclear weapons for warfare in history.

Kyshtym disaster The Kyshtym disaster was a 

radiological contamination accident that occurred on 29 September 1957 at Mayak, aplutonium production site for nuclear weapons and nuclear fuel reprocessing plant in the Soviet Union.

It measured as a Level 6 disaster on the International Nuclear Event Scale,[1] making it the third most serious nuclear accident ever recorded, behind the Fukushima Daiichi nuclear disaster and the Chernobyl disaster (both Level 7 on the INES).

The event occurred in the town of Ozyorsk, Chelyabinsk Oblast, a closed city built around the Mayak plant

The Fukushima Daiichi nuclear disaster

The Fukushima Daiichi nuclear disaster was an energy accident at the Fukushima I Nuclear Power Plant, initiated primarily by the tsunami of the Tōhoku earthquake on 11 March 2011.

The damage caused by the tsunami produced equipment failures, and without this equipment aloss-of-coolant accident followed with three nuclear meltdowns and releases of radioactive materials beginning on 12 March

 It is the largest nuclear disaster since the Chernobyl disaster of 1986 and the second disaster (after Chernobyl) to be given the Level 7 event classification of the International Nuclear Event Scale.[8]

Bhopal gas tragedy

The Bhopal disaster, also referred to as the Bhopal gas tragedy, was a gas leak incident in India, considered the world's worstindustrial disaster

It occurred on the night of 2–3 December 1984 at the Union Carbide India Limited (UCIL) pesticide plant in Bhopal, Madhya Pradesh. Over 500,000 people were exposed to methyl isocyanate (MIC) gas and other chemicals. The toxic substance made its way into and around the shanty towns located near the plant

victims  generation are still suffering from nuclear hazards  A disputed Russian publication, Chernobyl, concludes that

985,000 premature cancer deaths occurred worldwide between 1986 and 2004 as a result of radioactive contamination from Chernobyl.

The Kyshtym disaster, which occurred at Mayak in the Soviet Union, was rated as a level 6,

8,015 people had died within the preceding 32 years as a result of the accident

HIROSHIMA, NAGASAKI Within the first two to four months of the bombings, the acute effects of the atomic bombings killed 90,000–146,000 people in Hiroshima and 39,000–80,000 in Nagasaki; roughly half of the deaths in each city occurred on the first day.

Nuclear safety Nuclear safety covers the actions taken to prevent

nuclear and radiation accidents or to limit their consequences. This covers nuclear power plants as well as all other nuclear facilities, the transportation of nuclear materials, and the use and storage of nuclear materials for medical, power, industry, and military uses.

The nuclear power industry has improved the safety and performance of reactors, and has proposed new safer (but generally untested) reactor designs but there is no guarantee that the reactors will be designed, built and operated correctly

There should be a limit and rules on the use of nuclear energy

Fire hazards

Definition - What does Fire Hazards mean? Fire hazards include all types of live flames, causes of sparks, hot objects,

and chemicals that are potential for ignition, or that can aggravate a fire to become large and uncontrolled.

Catching the fire Poor housekeeping. Un-emptied grease traps (possible grease fires) Dirty ducts (possible flue fires) Improper storage of flammable items. Faulty or frayed electrical cords.

Be careful about the nuclear energy :>it can give us a lotand also>it has the power to vanish everything
