The most horrible nuclear accident in history: the Chernobyl nuclear leak

Chernobyl nuclear leak

The United States "Time" magazine has reviewed the history of the most terrifying of the top ten nuclear accidents, Chernobyl's nuclear leak was among the impressive!

April 26, 1986 morning, the Chernobyl nuclear power plant No. 4 reactor exploded, eight tons of strong leakage of radiation, followed caused the fire, resulting in the release of atomic bomb equivalent to 400 times the radioactive fallout into the air Covers nearly 1,600 square kilometers. In the next 25 years, tens of thousands of people around the city of Pripyat, where the Chernobyl nuclear power plant is located, suffered from cancer and talked about "nuclear" discoloration.

Today, most of the area around 30 km from Chernobyl remains in ruins, disappearing and becoming a veritable “city of death”.

A veritable "city of death"

The end of man-made disaster

As the first nuclear power plant of the former Soviet Union , the Chernobyl nuclear power plant was built in 1977 and was named after former Soviet prime minister Lenin. At that time, the former Soviet Union claimed that the safety performance of the Chernobyl nuclear power plant was the highest in the world, and it was regarded as a symbol of surpassing the United States during the "Cold War."

April 26, 1986 evening, Unit 4 nuclear power plant workers ordered to stop testing when the test reactor self-powered system, named "rock" nuclear power plant integrated information computer sends an abnormal signal, however, the operating system of a nuclear reactor engineer In violation of the directive, all safety systems were turned off by mistake.

In after 15 seconds, which is 1:23, uttered a dull explosion reactor ring, weighing 1,200 tons reactor lid was thrown into the night sky. After a few seconds, the more violent second explosion will crumbling the building’s earthquake, followed by 8 tons of radioactive material mixed with hot graphite and nuclear fuel. Humans have so far only been the 7th largest nuclear leakage accident, and the most horrible nuclear power plant leakage accident in history has occurred!

Terrible "rescue"

Less than half an hour after the explosion, the third guard of the second military firefighting team at the Chernobyl nuclear power plant rushed to the scene. Immediately afterwards, the Sixth Independent Military Fire Guard and nearby fire brigades were all transferred to nuclear power plants.

What is terrible is that these firefighters who arrived at the scene at the first time did not understand the dangers of nuclear radiation to the human body, and no one told them that they would not hesitate to carry out rescue and firefighting operations without protection. Under intense radiation, these firefighters soon felt extreme discomfort, vomiting, weakness, dizziness ...... followed, that night, there were two firefighters died, but a few months later, 28 people due to radiation Cancer died in pain.

When a widow of firefighters faced the media at the time, he said:

I looked at her husband (firefighters) died within 14 days.

Death of a firefighter

What is even more frightening is that after the former Soviet Union, nearly 500,000 "cleaning technics" were dispatched into the Chernobyl area within 30 kilometers after the removal of radioactive contaminants. Under the shabby protection, these people were still unable to resist the invasion of radiation. Afterwards, most of these "cleansing and purifying" diseases were plagued by premature death.

Is there a nuclear leak in China?

The National Energy Administration disclosed at the end of 2012 that the country’s total installed power generation capacity reached 1.144 billion kilowatts, including 12.57 million kilowatts of nuclear power , accounting for 1.10 percent of the country’s total installed capacity . And as of September 4, 2014, the mainland has been completed and put into commercial operation of nuclear power plants 8, Zhejiang Qinshan nuclear power plant one, two, three, Guangdong Daya Bay Nuclear Power Station and Ling Ao Nuclear Power Station were one, two Tianwan Nuclear Power Station in Jiangsu Province , Units 1 and 2 of Hongyanhe in Liaoning , Unit 1 in Ningde, Fujian , Unit 1 in Fangchenggang , and 20 units in Yangjiang Nuclear Power Station .

In addition, according to the National Development and Reform Commission's vision for nuclear power: By 2020 , China's installed nuclear power capacity will reach 36 million kilowatts. This means that China will also build at least eight nuclear power stations.

Faced with the terrible and terrible nuclear accident involving Chernobyl’s nuclear leak, we cannot help asking: Will China have a nuclear leak?

As early as 2004 , Li Ganjie, former director of the Department of Nuclear Safety of the State Environmental Protection Administration and present Minister of Ecological Environment, said in an exclusive media interview:

In our country, from the siting of nuclear power plants to the design, manufacture, construction, commissioning, operation and decommissioning, we must carry out effective nuclear and radiation safety supervision. As long as we strictly follow laws and regulations, it will not happen. safe question. It should be said that we have confidence in the safety of nuclear power and China's nuclear power security is guaranteed.

Among China's nuclear power development in the past 30 years, the nuclear accident in the reactor only occurred in May 23, 2010 China's first generation of nuclear power plants in Shenzhen Daya Bay Nuclear Power Plant. This accident was extremely small and would not pose a danger to the public or affect the lives of local residents.

Conclusion

Nowadays we cannot do without light and electricity.

Nuclear power can solve the problem of energy shortage, and it can also make our country's technological level improve overall. While looking at the globe, the occurrence of nuclear leakage is also a very small probability.

In the end, Xiao Bian hopes that the nuclear explosion of Chernobyl in the former Soviet Union, like the nuclear leakage of Fukushima in Japan ... will never happen again, and it will never happen in China.
