Academician Yu Jun Chong: Yu Jun made a wave of waves

Wen ｜ Shen Cong Mana Sun Chaohui

"Yu Junchong (1940.12.5—), nuclear power expert. Born in Binhai County, Jiangsu Province. In 1965, he graduated from Nanjing Institute of Technology (now known as Southeast University). Designer's project development chief designer. "On the website of the Chinese Academy of Engineering, the introduction of Academician Yu Junchong was concise and concise. At first glance, it seemed to be inconspicuous.

In fact, in the brief introduction of him, the description of vagueness and simplicity is not uncommon -because of the high degree of confidentiality, many tasks that Yu Junong had done was "invisible".

For decades, the participants of the nuclear -powered cause have stepped up step by step, witnessing and witnessing the entire development process of China's nuclear power industry, and made important contributions to it.

Most of his scientific research careers are spent in the deep mountain base. "It’ s shocked to the earth, and to be a famous name for the surname. "

Through the silent "invisible" work gap, you can still see Jun Chong's endless wave of life.

There is a poor family in the chaos, and the road to study is difficult

Yu Junbao

In 1940, Yu Junchong was born in Fa Village, Binhai County, Jiangsu Province.

He is the eldest son of the family. When he was born, he had only half acres of fields. There was no house. His father gave the landlord as a long job. It was not until liberation that the life at home improved.

However, the poor family has not become an obstacle to Yu Junchong's reading. "My parents are unknown farmers, and they have suffered from the suffering of dislikes, so the idea of ​​letting me read and literate is simple and strong. In order to give me reading, they save money and use them. The neighbors advised my parents not to do it for me, and went home to earn work, but they were always determined. "Yu Junchong recalled this.

Yu Junchong began to study in the elementary school in Murakami, named after a local martyr's name in the long -term Fa, called "Changfa Primary School".

Although Binhai County was liberated in 1946, Yu Junchong's hometown belonged to the "Liberation Zone" and "Jiangchuan District". Pass. Every time he heard the sound of the plane, the teacher took the students to hide in the reeds behind the school.

At that time, the conditions of school were very poor. At the beginning, four grades were squeezed in a classroom in a classroom. At the third or four grades, they were scattered in the houses of the hometown in the hometown of the villagers.

However, Yu Junchong, who has been very sensible since he was a child, cherishes rare learning opportunities. From the first grade to the fourth grade, he has risen steadily, and has successfully entered the Eastba Primary School in Binhai County to study in high school.

In 1954, Yu Junchong was admitted to Binhai County Middle School. It was very difficult for the primary school to take junior high school that year, and the admission rate was only 15%. At that time, the state called on Xu Jianxiu, a Shandong girl, and graduated from elementary school to go home to work at home. Three years later, Yu Junchong was admitted to Binhai County Middle School High School.

From junior high school to high school, Yu Junchong lived in six years. At that time, the school accommodation conditions were very poor, and they were sleeping in Datong. Everyone was squeezing together at night. The students joked that they were "seedlings" (potato is sweet potato, which means that they were tightly arranged like breeding).

There are no mattresses in winter, and can only be covered with thick straw on the wooden boards, and the straw is paved with straw mats.

The winter in northern Jiangsu was very cold, minus ten degrees, and there were no heating equipment in the classrooms and dormitories ... In Jun Chong's later memories, the life of that era was not worth mentioning. The trouble was that the political movement delayed learning.

Shortly after Yu Junchong went to high school, he was encountered in 1957's rectification movement and the anti -rightist struggle. Opinions are much.

In the later stage of the exercise, there were classmates who were criticized, and Yu Junchong always told the truth with his conscience in the exercise.

Immediately afterwards, the "Great Leap Forward" movement began again, and the school stopped classes. Each classmate was asked to participate in large steel refining, and to lift the ore at the port of more than a dozen miles of roads. Each class was a small dirt blast furnace.

Then they organized students to go to the countryside of more than 40 miles to help the people's communes collect peanuts and dig potato. After returning to school, they would get rid of the four harms (grabbing sparrows, mice, etc.), factories and other campaigns ...

There is almost no lesson in the first year of high. After a year, after the final exam, the class teacher Xu Gongwang specially praised Yu Junchong, then the then study member: "Other people's grades have fallen, but you don't." Because Yu Jun Chong knows that it is not easy to go to school, it is not easy to go to school. In addition to actively participating in various sports, I have never forgotten to study.

The dynamic dynamics of the knot is "destined to hit"

Yu Junchong's initial understanding of nuclear power originated from a magazine that he read in middle school. The name of the magazine can't remember it. The atomic energy is introduced above, and a match box size of uranium 235 can drive a lot of trains around the earth. This was impressed by Yu Junchong at the time.

It seems that this statement is not accurate enough, but at that time he had a strong interest in nuclear energy because of this statement.

With this interest, during the college entrance examination in 1960, Yu Junchong wanted to fill in the Department of Engineering Physics of Nanjing Institute of Technology, but for various reasons, he finally declared and admitted to the school's engineering thermal physics (industrial heat worker) major.

In college career, there are three years of difficulties. For a long time, only winter melon and sauce every day are melon and sauce. When students lined up, they always knocked on the bowl and shouted neatly "Winter melon -sauce, sauce -sauce -sauce -sauce -sauce -sauce -sauce -sauce -sauce -sauce — sauce — "Winter melon sauce" is like knocking gongs and drums. Some students become swollen due to malnutrition. However, the school's schoolwork did not relax for a moment. Students had to take 6 days a week, and after 10 o'clock in the evening, everyone consciously did their homework or review their homework on Sunday morning.

"At that time, there were thirty -six -seven professional courses, more than other majors. The classmates were bitter. The director Wu Darong did the ideological work: You are very good. Other majors have the problem of changing their careers. Your major does not change the problem You all have a place where you have a chimney. "Yu Jun Chong recalled.

Wu Darong was an expert in mechanical and electrical. At that time, there were many famous "everyone", such as boiler experts, motor experts, power mechanical experts, material mechanics experts, engineering thermodynamics experts, etc., all gave them classes.

Yu Junchong later said, "Fortunately, I learned a lot of courses and explained the famous teacher, laying a solid foundation for my future work."

In July 1965, he graduated from Junchong University and was assigned to the Ninth Research and Design Institute of the Second Machinery Industry Department (called the Ninth Academy of the Second Machinery Department, and today China Engineering Physics Research Institute), and reported to Xining City, Qinghai Province.

Zhang Dingxiang, the deputy secretary of the department of the department, told him: "That's a top secret unit. It is very good. I recommend you to them and do it well." Yu Junchong was very excited after hearing it.

Unexpectedly, after the registration, Yu Junchong was arranged to the Siqing Working Team of Qinghai Province before he arrived at the unit and went to the rural areas to engage in the Siqing movement.

Four months later, Siqing has not ended. The nine hospital sent the team leader to the Siqing Working Team to manage the students. Yu Junchong talked: "Because of an important project in the country, the professional person in the shortage of thermal workers should be transferred to work. The unit is the second department of the Second Machinery Department and the Second Hospital. "In the unit, the unit was called 715, namely the China Nuclear Power Research and Design Institute (referred to as the nuclear power institute, and its development process was the dual development of the" Second Machinery Department "and the" Navy ". Out of confidentiality, use and change the predecessor of multiple generations).

After Yu Junchong arrived in the unit, he learned that the major of their school was assigned to other units of the second machine department that year was also transferred to 715. Among the three, the first report was assigned to the theoretical analysis of the theoretical analysis of the theoretical analysis of the theoretical analysis of the theoretical analysis of the theory of thermal workers in the nuclear reactor.

Yu Jun Chong recalled: "At first, it was really difficult. I did n’t have the professionalism. I have never heard of what reactors, and this work must also understand the knowledge of heap structure, pile physics, heap control, system and equipment. I haven't learned it. In addition, the daily work mainly investigates the relevant physical models and calculation methods from English materials, and I have never learned English. The only knowledge I have learned is heat transfer and fluid mechanics. "

In the face of difficulties, Yu Junchong rejected the proposal of the cadre department leader to transfer to the department, secretly determined to work hard to tutor himself.

During the "Cultural Revolution", the unit stopped production and the revolution, and Yu Junchong still seized all opportunities to learn. After several years of hard work, he basically adapted to work.

In more than three years in Beijing, in addition to participating in the income (calculating ruler and hand -shaking calculators) to expand preliminary design, the rest of the time followed the old comrades to investigate the relevant calculation methods. English.

After turning around, Yu Junchong finally entered the gate of the nuclear industry. For decades, the project he participated in and led was breeded from the deep mountain base and made a fruitful fruit. To this day, Yu Junchong still overcome difficulties and overwhelmed his thorns in the field of nuclear power with his love of work.

The mountains are towering, but the way before

In 1969, Yu Junchong took a photo in the Great Wall in front of the 909 base.

In September 1969, 715 was ordered to move to the third line. Yu Jun Chong and his colleagues sat in the army for three days and three nights, and came from Beijing to the ditch in Sichuan.

At this time, the China Nuclear Power Research Base, code -named "909", has begun to take shape. Those who are waiting for these young people are the construction of the first -generation nuclear submarine in the mountains in the mountains (hereinafter referred to as the model pile). project.

This is a hidden job. Facing the inquiry of the local people, they just said that they belonged to the "Southwest Hydropower Research Institute" and came to Sichuan to develop hydropower.

After 909, the professional team leader Yu Junchong participated in the preparation of the steady -state program. Because the computer ordered the computer is about to be put into use, Yu Junchong is responsible for investigating the calculation method of the two -phase objection, and at the same time participating in the two -phase obstruction test of the unit.

After the mode of mode was commissioned, Yu Junchong was arranged to the thermal laboratory on duty to calculate the thermal power of the reactor.

Fortunately, the time when the mode reaches reaches full power, it is catching up with Yu Jun Chong Dangdan, which makes him fortunate to be the first person to calculate the mode of power to reach the power; The completion of various experiments) also came from Jun Chong's hand; the model of the mode of heat work in the mode was also completed by Yu Junchong.

After the successful research and development of my country's first model, the unit did not have a specific development task. At this time, the superior decided to put the 715 from the Navy to the two plants from the Navy, and the complete submarine nuclear power device design research institute was split into a reactor reactor. (Within the control of the tube, excluding instrument control) and the rest are divided into two industrial departments -the second and sixth machines. This kind of splitting, a little nuclear -motivated common sense can see extremely inappropriate, Yu Junchong attributed it to the "Cultural Revolution" product.

Yu Junchong was left in the original unit (715), and he was transferred to participate in the pre -research work of the new plan at this time.

In this case, no design scheme was unanimously recognized by the three departments and four units participating in the plan.

Although a scheme has not been done, Yu Junchong still "profit" -the use of this opportunity to make up for the various heap types of knowledge used in the plan research.

This unreasonable split continued until 1975, and then returned to the one -circuit system under the leadership of the Central Committee to the reaction.

In the 1980s, the enthusiasm of the construction of nuclear and electricity in the country began to rise. Yu Junchong took precautions, investigated the hydraulic analysis model of the nuclear power plant, and wrote the code (at that time it was still binary) to complete the development of the nuclear power heating water pile design program.

Due to the unfamiliar computer management software in development, Yu Junchong touched countless walls and had suffered a lot.

After the procedure was completed, he named it "self -contribution", and briefly as "CCCC" for dialect reasons.

When colleagues asked the meaning of "CCCC", Yu Junchong always laughed without answering. In fact, it was because he did not work (code), and his wife said that he was "self -sufficient".

The procedure was later used in the design of the "Kingsoft Nuclear Hot Power Station" and other pressure piles.

At the same time, after research and demonstration, the nuclear power institute decided to develop pulse reactors, which is safe, economic, functional (scientific research, teaching, radiation, etc.).

However, at that time, the technology was only exclusively controlled by the US GA company. The hospital decided to organize personnel to conduct scientific research, and Yu Junchong was also being transferred.

The pulse heap is different from the built -up mode pile. It can run the pulse. The power can be increased by more than a dozen levels instantly, and it is a natural cycle cooling.

If the technology is introduced from the United States, the United States requires China to buy six pulse piles before transferring technology.

After hearing the price of the United States, the researchers felt like the "alliance under the city" and unanimously expressed independent research and development.

They only got started with the safety analysis report of the pulse pile of the State University of Washington, and worked hard with their professional foundation.

According to the theoretical model based on the basic principles of pulse and natural cycle, Yu Junchong has compiled the natural circulation steady -state analysis procedure, natural circulation pulse analysis procedures, and water loss accident analysis procedures, and used these procedures to complete China's first pulse reactor thermal worker. Design and security analysis.

They started the construction of the pulse heap without any simulation test verification. After completion, the actual stack measurement results were completely coincided with the theoretical analysis of the above -mentioned self -edited program.

In the early 1990s, Yu Junchong used natural circulation technology to solve many engineering problems, such as Pakistan's study of pile upgrades, Thailand's research on the application of non -dynamic waste heat excretion systems, and the natural cycle capacity of power stacks. Design, etc.

Among them, it is worth mentioning that Yu Junchong found natural circulation capabilities on the Minjiang Pile, and used it to solve the problem that could not set up an emergency cooling system.

It was in 1990 that the nuclear power institute decided to transform the original high -throughput zero power device into a 5 MW test heap, but it was impossible to set the emergency reinforcement cooling system. So they found Yu Jun Chong.

Through analysis, Yu Junchong found that a natural cycle can be achieved between the central and block gaps between the center of the block and the block of the blocks of the Minjiang River and the large pool, bringing the core heat of the pile to the large pool to achieve the cooling of the core.

Through the calculation of self -editing procedures, Yu Junchong discovered that about 15%of natural cycle capabilities.

For conservative reasons, he said that "has a natural cycle of not less than 10%", and no one believes.

The group company organizes expert review and believes that it is impossible to have natural circulation capabilities, and even experts who have worked on high -throughput piles for many years have objections. Yu Junchong is convinced of his judgment and calculation.

If there is no natural cycle capacity of the Minjiang Pile, a emergency waste heat guide system must be built, but it is actually difficult to implement due to the environment and funding of the pile factories. The project register for the Nuclear Safety Bureau, and the relevant experts do not think that they can have natural circulation capabilities. Finally, in the approval letter, it stipulates that the power is increased to 10%to do the natural cycle ability test. To 100 % power.

During the real pile test, the staff of the Nuclear Safety Bureau went to measure and witnessed on the spot, and the results proved that Yu Junchong's judgment and calculation were completely correct.

Don't forget your original intention, know difficult

In 2000, Yu Junong took a photo in the office.

In 1993, Yu Junchong was transferred to the director of the key engineering chief design office of the nuclear power center, responsible for the overall design and design management of the project (including internal and external interface management and coordination).

In fact, as early as the pre -research stage of the project, Yu Junchong devoted himself to it, and led the entire group and other professionals as the professional team leader to make the efforts that the heated work and the overall parameter index were determined.

In the meantime, under the circumstances of all equipment structure and unsure system layout, the natural circulation capacity indicators and security conversion methods were determined, and it was recognized by experts and leaders in all aspects. This is indeed easy. Yu Jun Chongyong picked up the burden, and lived up to expectations. The actual test after the completion of the project proves that his original work was accurate.

After hosting the work of the General Design Office, Yu Jun Chong was deeply responsible. Once, he found that in a plan that had been approved by the higher authorities and coordinated with the relevant interface unit, there was a key point incomplete. Therefore The safety and reliability of the project does not affect other performance.

The modified plan was recognized by the peers, the recognition and approval of the superior agency, and the project was officially adopted.

In terms of design and management work, Yu Junong's work is organized in each stage: the transmission between dozens of majors, countless drawings, and data such as internal and external interfaces, countless drawings and materials are in order. The daily work of the deputy chiefs is arranged in an orderly manner.

In 2000, Yu Junchong was appointed as the deputy chief planner of the National Key Project, which coincided with the construction design of key projects. Some people said that this was "picking peaches", but the fact is that this is a "hot potato", which is a "hot potato". The work is not easy to do -the problems that cannot be found on the design drawings. After the development of the product production and the development of scientific research machines, especially after the installation of the joint adjustment, due to the inadequate debugging of the relevant equipment in the development of the prototype or the production of the product, it has not been sufficient for various reasons, and it has not been sufficiently debugged, let alone not, let alone, let alone, let alone, let alone. Pre -installation of non -nuclear tunes before the decoration is exposed one by one in the general installation.

In the process of dealing with the problem, it is necessary to solve the problem in accordance with the principle of "double and five to zero" as soon as possible, but also coordinate and balance the game between units in terms of responsibility and interests. The process is not always calm, sometimes even quarreling and shooting tables.

As a person in charge of the unit's technical and deputy chief designer of the engineering director, Yu Junchong started from the heart of the public, making full use of his knowledge and wisdom. In the face of all kinds of contradictions and problems, he can always transform Gan Ge into jade and solve it successfully.

In 2006, according to regulations, Jun Chong should retire and leave the post, but the project was not completed at the time, and Yu Junchong extended his retirement by the superior authority and negotiated by the nuclear industry group until the project was delivered.

Recalling the pressure of the work in the past few years, Yu Junchong has still been worried so far. In the process of joint adjustment, more than 30 types of equipment and sub -systems have caused more than 30 problems.

"At that time, when someone called me at the scene, the hair was erected, and the pressure was really very large." Yu Jun Chong had high blood pressure. During that time, even if one drop of blood pressure was changed every day, blood pressure was all blood pressure. If you can't drop, the scalp hurts when you touch it.

Tiandao rewarding, decades of efforts to pay for Yu Junchong to win the national and provincial and ministerial level scientific and technological achievements awards, as well as many other honors, including nuclear industry, national defense science workers, national chief unions, the Party Central Committee and the Party Central Committee and the Party Central Committee and the Party Central Committee. The State Council jointly issued by the State Council.

When it comes to these honors, Mr. Yu Junchong said: "Everyone has done it together.

In 2009, Yu Junchong was elected as an academician of the Chinese Academy of Engineering.

Hsinchu is old dry, peaches all over the hall

Although Yu Junong's work was very busy, he has never forgotten the cultivation of young people. Since the end of the 1980s, he brought out a number of master's degrees, doctoral students, and post -doctoral students.

Today, most of the students he have trained have become professional backbones.

In the eyes of the students, Teacher Yu is very busy, but the requirements for the students are very strict. They will read the student papers carefully. If they are not satisfied with the dissertation, they will never let go.

However, Teacher Yu just pointed out the problem and let the students study and solve it until he was satisfied.

In addition to students, Yu Junchong also attaches great importance to the help and training of young people who work together.

It turned out that several young people run by the chiefs grew very quickly, and some had become the administrative leaders of the hospital, and some became the chief engineer, deputy chief engineer, assistant dean and chief project chief of the hospital.

In their opinion, their progress and Yu Junchong provided them with exercise environment, let go to make them work, and speak.

Yu Junchong still did not forget his support for his hometown education. In March 2021, he and his wife donated funds for his alma mater, Binhai Middle School to set up a "Binhai Hope Star" reward fund for students with excellent academic science. I hope to cultivate more outstanding talents for the country.

Yu Junchong, an outstanding scientist who came out of the poor countryside in northern Jiangsu, was the first scholar, the first college student of their ancestors, and the first academician of the Chinese Academy of Engineering from their county.

He attributed all this to the result of the cultivation of the party and the state.

Over the years, everything he has done for the party and the country has been unknown, and there are seals of his sweat.
