He made China’s nuclear technology “build tall buildings from the ground” again and again.
Wu Sheng, member of the Chinese Academy of Engineering, is an expert on nuclear materials and technology.He has won many national and provincial awards and twice won the Special prize of national Science and Technology Progress Award.With his efforts, China has solved the technological problems of nuclear fusion materials, mastered the key technology of processing and forming, and developed uranium alloy materials with high toughness and excellent corrosion resistance.On July 18, 2008, Wu Sheng in guiding work often talk about their own contribution, he always said: “the older generation of scientists incognito decades, for China’s nuclear weapons cause made a great contribution, compared with them, I still far away.”Wu Sheng was born in Acheng County, Heilongjiang Province in September 1934.At that time, the social turmoil, the family life is embarrassed, in such conditions, Wu Sheng still insist on reading, maintain the thirst for knowledge.In 1950, the People’s Republic of China issued state grants to students from poor families. Wu Sheng, who had been underfed and underclothed, was finally able to devote himself to his studies.He treasured the hard-won opportunity, out of love for the new China, he joined the Chinese New Democratic Youth League and actively engaged in the movement to fight against the United States and aid Korea.In June 1952, after demobilization, Wu Sheng entered Acheng No. 1 Middle School to continue his high school studies.In August 1953, he became a member of the student Party of Acheng No. 1 Middle School and was elected as the only student representative of the first Session of the People’s Congress of Acheng County.In 1954, Wu Sheng ushered in an important opportunity in his life, he was recommended to stay in the Soviet Union reserve department with excellent results, began a one-year Study of Russian.In order to better study in Russia, he often remedial Russian late into the night.”I never thought about going to college, much less abroad.”The love of the motherland and the people made him feel the heavy responsibility on his shoulders. The great contrast between the old and new times also made him further strengthen the firm belief of “being grateful for his long life and serving the country” and devote all his energy to his studies.In the early days of the founding of the People’s Republic of China, China’s non-ferrous metal industry was very backward and in urgent need of a large number of non-ferrous metal professionals.In this context, Wu Sheng entered the Non-ferrous metal and Gold Institute of Moscow in September 1956 to study non-ferrous metal pressure processing.He eagerly absorbs all kinds of professional knowledge of non-ferrous metals. In four years, he has mastered solid basic knowledge, deepened theoretical understanding, and acquired profound professional foundation as well as good practical ability.These skills played an extremely important role in his future work.In 1957, Wu Sheng in The Moscow institute of nonferrous Metals do in June 1960, Wu Sheng with excellent results to complete the graduation defense, and on the spot won the title of metallurgical engineer.Then he immediately returned to China, in order to repay the motherland and the people with the knowledge as soon as possible.In October 1960, Wu Sheng entered to meet the needs of China’s nuclear weapons development and the establishment of the second division of Beijing ninth Research Institute, involved in the first atomic bomb research and development work.The development and production of nuclear components of atomic bombs is a complex task involving multi-disciplines and multi-fields. Wu Sheng and his colleagues are mainly responsible for the heat treatment of nuclear components, which is the most critical and important technological technology.At this time, a huge problem was placed in front of the team. None of them had ever seen elemental uranium, nor knew its physical and chemical properties, nor did they have a ready-made heat treatment process.”What shall I do?Rule 1: anyway is can’t wait, must come out.The Soviet experts would not give us guidance, and we were so frustrated that we were determined to work it out, not to mention whether we could.Rule two: mount the horse with native methods.We didn’t have anything ready, so we worked on our own.”Wu and his colleagues decided to be self-reliant, “learning what we don’t know and what we need to learn.”He first studied the physical and chemical properties and related knowledge of the nine actinides in mendeleev’s periodic table related to synthetic artificial nuclear reactions, and then explored in depth the knowledge related to casting, and the establishment and measurement of vacuum systems.After mastering relevant knowledge, Wu Sheng also actively communicated with other colleagues to create a strong learning atmosphere for the scientific research staff of the institute, which greatly encouraged their enthusiasm in learning. At that time, during the three-year natural disasters in China, everyone’s monthly rations were limited. Wu Sheng and his colleagues were bloated due to hunger.But in order to “break the imperialist nuclear monopoly and nuclear blackmail” and “safeguard the security of the motherland” ideals and beliefs, they still with extraordinary perseverance.With everyone’s unremitting efforts, the Ninth Institute has successively completed the theoretical design of atomic bomb and the refining of highly enriched uranium.In 1964, in order to concentrate on the annihilation war, the ninth Bureau of the Second Aviation Department decided to carry out the “Prairie Battle”.Wu Sheng and colleagues are sent to Qinghai, they and the experts from all over the country, scientific research personnel, technical workers began nervous and orderly “two bombs” development tackle key problems.The harsh natural and living conditions on the Qinghai Plateau did not affect their passion to fight and their faith to win.Under the guidance of zhu Guangya, Chen Nengkuan, Long Wenguang, Zhang Xingqian and other scientists, song Jiashu and Wu Sheng led the staff of the whole workshop, and first conquered a number of technical difficulties in the precision casting of the core components, providing components that met the design requirements for the principle test of the atomic bomb.After the successful explosion of the first atomic bomb, Wu Sheng and others immediately into the hydrogen bomb thermonuclear components molding technology work.They adopted the way of simultaneous exploration of multi-way technology, which effectively mobilized everyone’s enthusiasm and accelerated the progress of tackling key problems.Finally, they successfully established the component forming process state control and safety experiment system, designed and adjusted the component forming process device structure, systematically studied the influence of process parameters on the microstructure, defects and related properties of the product, and provided components meeting the design requirements for the first hydrogen bomb prototype test in China.In the mid-1980s, according to the national strategic deployment, China began to develop a new generation of equipment.The wu Sheng of some plant chief engineer that develops production as nuclear component once again provoked “ground ground rises tall building” heavy burden.Wu Sheng’s first challenge is the development of high-performance uranium alloy components.In order to solve a series of technical problems such as smelting, molding, processing and performance testing, Wu Sheng developed an experimental scheme according to the development requirements, and began to tackle key problems with the team.The research team selected the raw materials, improved the quality of the coating on the surface of the crucible and the casting mold, and made innovations in preparation. After many tests, the alloy components finally had excellent mechanical properties and corrosion resistance, which successfully reached the international advanced level at that time, and played an important role in its engineering application.As the chief engineer, Wu Sheng not only listened to the progress report and grasped the research direction in the office, but also discussed and analyzed various problems with the technicians on the first-line experiment site, guided the specific experimental details and helped everyone to have a deeper understanding of the research materials.In 1991, Wu Sheng directed his work at the front line of scientific research and production, and kept learning with his students. In the 1980s, faced with the shortage of young people and successors in the nuclear materials research team, Wu Sheng and the older generation of scientific researchers established the program to grant master’s and doctor’s degrees in nuclear fuel cycle and materials.Attract and cultivate high-end talents in the field of specialty materials research.In 1994, Wusheng began to plan the establishment of the Key Laboratory of Surface Physics and Chemistry, formulated the ten-year plan for scientific and technological development and the ninth five-year Plan, and carried out major research projects.Over the next ten years, he advised the lab on its development.In 2003, the first national Defense Key Laboratory of Science and Technology in the field of metal materials was established, aiming at the compatibility research of special materials.Under the leadership of Wu Sheng, the laboratory has not only established good cooperation and exchange relations with domestic first-class scientific research institutes, but also made many significant progress and scientific research achievements in various research directions, reaching the domestic leading and international first-class level, providing strong technical support for the development of National defense equipment in China.Wu Sheng is very strict with young researchers, especially his students, and emphasizes the most is “learning”.And he himself has always been to teach by example.He taught his students to be rigorous and long-term in their studies and not to worship foreign experts blindly.In addition, we should pay close attention to the frontier dynamics of the discipline and make bold innovations according to the actual situation.One of Wu’s students once said, “Teacher Wu is always thinking about science and engineering.Every time I visit him, even when he is sick, he talks about what we need to focus on and what new technologies and knowledge we need to learn.”March 14, 2008, Wu Sheng in the office work this year has been 88 years old Academician Wu Sheng, still not forget the frontier development of nuclear materials and technology direction, not forget the training and growth of young scientific and technological talents.He has been hoping to pass on his knowledge and experience to young researchers, and at the same time pass on the Chinese scientist spirit of “patriotic dedication, hard work, collaborative research, truth-seeking and innovation, and scaling new heights”, so as to help the continuous development of science in the motherland.
