The Science and Technology Heroes Series 2 that promoted the development of New China - Wang Ganchang led the first underground nuclear test

At the end of 1960, Wang Gan (gan) Changfeng of the Joint Nuclear Research Institute in Dubna, Soviet Union, was transferred back to China. One day in March 1961, Wang Ganchang, who had recently returned to China, climbed the building of the Second Machine Department with great energy. As soon as I walked into the minister's office on the second floor, I saw Liu Jie, then director of the Second Machine Department, and Qian Sanqiang, a famous scientist, waiting for him.

Minister Liu Jie conveyed to him the decision of the Party Central Committee and asked him to report to the Nuclear Weapons Research Institute within three days.

If Wang Ganchang accepts this decision, it means that he will henceforth leave the basic research work that he is familiar with and has achieved important results, and instead do the applied work that he is not familiar with. However, Wang Ganchang agreed without hesitation.

At that time, he only said one sentence: "I am willing to pledge myself to the country!"

The next day, Wang Ganchang went to work at the Nuclear Weapons Research Institute. Previously, Wang Ganchang caused a sensation in the world because of the discovery of anti-Sigma negative super son, and he has long been famous in the world. So Wang Ganchang, then 54 years old, was one of the older scientists involved in the development of nuclear weapons at that time.

Wang Ganchang bid farewell to his family and came to the Northwest Nuclear Weapons Development Base alone, saying: "It is glorious to be able to contribute to the rise and fall of the country, and everyone is welcome."

At that time, the base had just begun to be built, and the conditions in all aspects were very poor, and in the Qinghai Plateau at an altitude of 3200 meters, the cold was cold and oxygen-deficient. In such a harsh natural environment, young people will gasp when they walk fast. Wang Ganchang, who is more than half a hundred years old, does not care at all, he insists on going deep into the workshop, laboratory and test site to understand the situation, guide the work, discuss problems with comrades with great interest, and often work with everyone until late at night.

For each technology, every data, and the preparation of each experiment, Wang Ganchang strictly checked to ensure that each experiment was successful.

In the 'Atomic City' there is a yellow general building, which is mostly inhabited by core scientists such as Wang Ganchang, Peng Hengwu and Guo Yonghuai.

Chen Fei, an engineer at the Former 221 Factory who had participated in the work of making the atomic bomb at the time, later recalled:

Although Wang Ganchang is an "authoritative physicist and the core scientist of the two bombs, he often works with ordinary researchers to study design solutions."

In the mid-1960s, Chen Fei often met Wang Ganchang when he arrived at the "Atomic City", and also carried out relevant experiments and designs under his guidance. For scientific research, Wang Ganchang cannot tolerate sloppiness and procrastination. He always told everyone, "You have to be foolproof."

In 1969, under the leadership of Wang Ganchang, the relevant personnel began to prepare for China's first underground nuclear test.

Once, everyone was experimenting in a flat hole in the granite layer of the Gobi Desert, and scientific and technological personnel and warriors worked side by side in the tunnel.

However, the ventilation conditions in the cave could not keep up, and radon gas came out from time to time, and the concentration of the overdose increased.

After Wang Ganchang found the problem, he immediately took a series of effective measures and organized personnel to protect and monitor day and night.

Unexpectedly, Wang Ganchang's practice was criticized by some people, who ridiculed Wang Ganchang's practice as a "philosophy of life" Wang Ganchang immediately retorted: "What 'philosophy of life'? This is science, and science is the most pragmatic and realistic!"

In this way, under extremely difficult conditions, Wang Ganchang, despite his advanced age, together with other outstanding scientists, worked in anonymity to develop atomic and hydrogen bombs, thus making tremendous contributions to China's "two bombs and stars" cause.

When Wang Ganchang talked about his anonymous nuclear testing, he said with great affection:

In the life of a person, what is more valuable than contributing his modest efforts to the motherland, and what is more worthy of pride than seeing the growing strength of the motherland?
