[Discover the most beautiful you comment on me] "Hualong I" character: They are witnesses and witnesses

China Network Fujian, July 28 (Reporter Wu Jiayu) On January 30, 2021, the first pile of the three -generation nuclear power technology "Hualong One" independently designed and developed by my country -China Nuclear Group Fuqing Nuclear Power No. 5 was put into commercial operation and became a commercial operation. my country's independent innovation capabilities and core competitiveness of my country's nuclear industry are running from follow -up, and the leading leadership.

On March 25, 2022, the second unit of the "Hualong -1" demonstration project, the No. 6 unit of China Nuclear Group Fuqing Nuclear Power No. 6, officially had commercial transportation conditions. At this point, the "Hualong -1" demonstration project has been fully completed and put into operation, and my country's nuclear power technology level and comprehensive strength are among the world's first square.

Behind the achievement of these achievements is the workload of "huge". It is a result of several generations of nuclear industrial people, thousands of equipment manufacturers, tens of thousands of design, construction, installation, debugging, and continuity of operators. Essence According to rough statistics, Hualong I, as a precise system engineering, involves more than 60,000 (sets) equipment and thousands of people's R & D and design teams, driving more than 5,300 enterprises in the upstream and downstream industrial chain. Participated in the construction of demonstration projects and follow -up projects.

What kind of story is there? On July 26, at the "Finding the Most Beautiful Rating I Comment" - "Entering Hualong -1" online review brand activity meeting and exchange meeting, representatives of "Hualong One" demonstration project shared their stories in various fields.

Cao Yuhua: The first female "Golden Man" in Hualong -1 in the world

The manipulator is known as the "Golden Man" of the nuclear power plant, and the cost of the initial training of a manipulator is named after the gold of an adult. "Golden Man" is like the "brain center" of the crew, a "decision center" issued instruction, and an important responsibility of the crew's normal operation. Become a qualified manipulator, you need to go through strict selection and training, and go through nearly 100 tests and examinations.

Cao Yuhua is a trainer trainer of Fuqing Nuclear Power Hualong No. 1 manipulator. He is the first female "Golden Man" in Hualong -1 in the world. As early as 2014, Cao Yuhua had an inextricable bond with Hualong I, and successively served as the design document reviewer of Hualong 1, running preparatory engineers, theoretical trainers of manipulators, and part -time simulators training instructor.

In 2014, the Unit 1 of Fuqing Nuclear Power was still in the hot test stage. On that day, Cao Yuhua, who was a debug engineer, organized the work related to the comprehensive test of non -nuclear steam flushing and power loss of steam turbines. The person in charge of the office said: "Received a group of Hualong 1 design documents need to be reviewed, and you are responsible for organizing." Since then, Cao Yuhua has become a Hualong No. 1 design document reviewer, organizing and commissioning staff to review the Hualong I system manual and equipment technical specifications.

In 2018, Cao Yuhua was selected as the first batch of theoretical training teachers and part -time simulators training instruments in Hualong 1. At the same time, as the first batch of learning manipulators, he had to take the manipulator and senior manipulator exam. Due to the long training cycle of the manipulator, during this period, like other operators, she participated in the training during the day and worked overtime to prepare technical documents and handle daily affairs at night. In March 2019, Cao Yuhua passed the first batch of Hualong I of the first batch of Hualong I; in June 2019, the first batch of senior manipulator exams on Hualong I.

In January 2020, Cao Yuhua came to the training office and served as a full -time simulator training teacher in Hualong No. 1, and taught the research operation knowledge to students. As of now, Fuqing Nuclear Power has cultivated more than 100 Hualong No. 1 manipulation personnel, spreading in various fields such as operation, production planning, safety supervision, and training. She also organized the development of the "Hualong No. 1 Simulator Training Introduction" course, and took a 7 -hour videos in English to help Hualong No. 1 "going out".

"I am just an ordinary member of the construction staff of the Hualong No. 1 crew. Happiness originated from diligence, and the fragrance of plum blossoms is self -suffering. I have been running in the work of 14 years of nuclear power work, and has been struggling to achieve my own value." Cao Yuhua Huahua. Say.

Niu Pengliang: The guardian unit is our inconceivable responsibility

Niu Pengliang is one of the three places in Fuqing Nuclear Power. In November 2020, Niu Pengliang was fortunate to announce the grid of the world ’s first bunch of Fuqing Nuclear Power No. 5 in the world as a chief. The "Hualong One" demonstration project has been completed, can it be relieved? In Niu Pengliang's view, after completion, it is a comprehensive test of Hualong No. 1, and it will also face more and more tests.

The operator is the guardian of the unit. In order to ensure the safe and reliable operation of the crew, Fuqing Nuclear Power has taken various measures to improve the safety of the unit. Take the operation department as an example to improve the quality of regulatory documents through on -site steps and desktop deduction; to improve the reliability of equipment and factory buildings through the combination of boutique factories; Personnel behavior; to improve the knowledge skills of operators through regular exams, simulation machine training, emergency drills, etc.

In order to actively respond to the impact of the new crown pneumonia's epidemic, Fuqing Nuclear Power operates three offices and establish a backup value system. In a severe period of the epidemic, one of the six of the six operating values ​​live directly in the field. Once special circumstances occur, start the backup value immediately, and all the staff replace the duty value to control the crew to ensure that the unit is safe and reliable.

In the backup value, everyone has a family. During the implementation of the backup value system, the family lacks a top pillar. Nuclear safety. At this time, other personnel should guard the backup families to eliminate the worries of employees. "All efforts are just to use actual actions to brighten the" National Business Card "with actual actions. The guardian crew is our inconspicuous responsibility." Niu Pengliang said.

Gong Zhiming: Use "debugging and tuning" to brighten Hualong No. 1 "National Business Card"

Gong Zhiming, director of the Fuqing Nuclear Power Development Management/Production Preparation Division, is a veteran who has worked in the field of nuclear power plants for 20 years. As the main person in charge, he organized the debugging of Unit 5 and 6 of the "Hualong -1" demonstration project. Some people compare the debugging work as "minesweeper", which is the last level of many levels. In this session, it is necessary to ensure that all problems are found and resolved, leaving any hidden dangers to the production and operation of nuclear power units.

"Hualong No. 1" is the world's first pile is a super engineering. It has a large amount of engineering, many changes, "three new" equipment, tight debugging time, and heavy tasks. As the first pile project, the debugging experience of Unit 5 and 6 of Fuqing Nuclear Power can follow, and the team requires the team to continuously explore and summarize. In the process of batch construction of independent three -generation nuclear power technology and "going global" to provide valuable "first -hand information".

In March 2020, Unit 5 entered the preparation stage of the installation. For debugging, the most arduous task at this stage was to complete the debugging of more than 200 systems, and all the problems discovered were resolved and handed over to production. However, there are many problems in front of them, which are intricate, and one ring. Gong Zhiming led the team to integrate the problem into a list of more than 100 issues, and selected 50 of the most challenging 50 issues to carry out the "unveiled list". In the next time, under the unremitting struggle, "the defense test is still one worse, it can be completed today", "the speed of the steam -auxiliary pump is stable, the acceptance passes" ... the Jiebao frequently passed on, and the difficulties were overcome one by one.

From the beginning of 2016, the debugging was completed in March this year. For the full 6 years, Gong Zhiming led more than 500 people. More than 2,000 debugging tests, the operation of the unit after production shows that the debugging quality is good.

"As a nuclear power person who has struggled for ten years in the field of Fuqing nuclear power debugging, the sense of responsibility made by a safe and rigorous work style, climbing the sense of accomplishment brought about by peaks, has left profound ones in our career's career. Seal, this is the best gift for us. "Gong Zhiming said.

Fuqing Nuclear Power Maintenance three deputy deputy deputy director Yubing. China Nuclear Group Photo Conference

Youbing: Young people are more tough and help Chinese technology "go out"

The three deputy deputy director of Fuqing Nuclear Power Maintenance, Supreme Bing, has always adhered to the front line of the nuclear power control control and maintenance in 2008, and assumed the "Hualong -1" demonstration engineering crew to debug and repair the maintenance.

According to Youbing, there are many systems and equipment in Hualong's first piles. It is not a new system and new equipment that has not been applied in nuclear power units, and lacks mature experience that can be used for reference. During the unit Jian'an and debugging, the three maintenances were a young team. The establishment time was short and the team members were very young. The proportion of employees within 3 years of graduation reached 60%. On the one hand, the equipment is new, and on the other hand, it is new, but this does not let them stop "new", but use the strength of young people to fight for the problem.

After a female colleague who graduated in 2018 in the team, after entering the three maintenance, he chose to deal with relay protection, and chose the most complicated generator excitation regulation system. She came in and in the rain, squatting on the scene, exploring motors, and continuously drilling the principles of motor excitation systems, and mastered key test methods such as static functional tests of excitation systems and small current tests at the fastest time. In the context of lack of manufacturers' logical principles and facing foreign technology confidentiality, deeply digging and researching, break by one by one, and finally complete the compilation and verification of the online replacement scheme of the excitation board card, actively improve the self -maintenance ability, and accumulate valuables for the maintenance of the generator's excitation system. Experience and summary materials. In 2021, the manufacturer invited the female colleague's reverse technology output to guide them to test the board card.

During the first hot test of Unit 5, there was a problem of speed fluctuations in the steam auxiliary pump, but this time the supply manufacturer could not provide more effective technical support. Under the disadvantage of "internal focus and trapped", the maintenance team took the lead in setting up a special group for the problem handling, and conducted more than 50 tests for various types of experiments for difficult problems, and collected more than 100 groups of test data of pre -sequential units and peer power plants. After more than three months of unremitting efforts, the analysis and research project of key components was finally completed, breaking through the relevant technical barriers, the self -improvement and optimization of the components of the automatic pump regulation mechanism in the nuclear power field, and successfully solved the design of the original manufacturer's design. The defect has significantly improved the equipment performance indicators and has cured the problem of great fluctuations in the operation of the auxiliary pump.
