"Yang Dong, I know that you have designed and manufactured the key equipment and equipment of the thorium-based molten salt reactor nuclear power plant, especially the most critical high-temperature and high-pressure radiation-resistant seals of the key equipment, and I hope that you can provide key components such as the seals of the pressure vessel and the shielded main pump and the blasting valve for the nuclear power technology company. ”

Zhao Zhizhong said to Yang Jie.

"We're doing a good job of the seals for the nuclear power plant, but the shielded main pump we designed is suitable for high-temperature molten salt, not for pressurized water reactors, and it takes time to redesign and manufacture. ”

Yang Jie opened his mouth and said.

Huaxing Technology Group Co., Ltd. has been developing high-end equipment for so many years, especially in ultra-vacuum, cryogenic, automotive, aerospace, military and other technical fields are in need of a variety of high-performance seals, and the key components in this key equipment are naturally developed very early.

The sealing technology department of Huaxing Technology Group Co., Ltd. starts from the most basic material research and development, and has established a high-level testing and verification laboratory and advanced preparation production line for seals.

Through more than 10 years of continuous investment in research and development, these seals of Huaxing Technology Group Company have become the top suppliers of seals in the fields of petrochemical, thermal power, chemical, shipbuilding, high-end equipment, aerospace and other fields at home and abroad.

Huaxing Technology Group Co., Ltd.'s entry into the field of nuclear power plant seals also began after Yang Jie's acquisition of Gaila Energy Technology Company.

For large nuclear power plants, it is a key component of nuclear safety equipment and an important guarantee to prevent the leakage of radioactive materials.

A nuclear reactor has tens of thousands of large and small seals, which must be inspected and replaced every year after installation, and such a small seal has been monopolized by Eagle Sauce domestic companies for more than half a century.

For such a situation, Yang Jie was naturally unconvinced, and also obtained the sealing ring of the nuclear power plant through various channels for the following technicians to carry out research and development.

It took almost five years for the sealing technology department of Huaxing Technology Group Co., Ltd. to master the five core technologies of sealing material combination technology, irradiation accelerated aging technology, force model analysis and leakage, and developed a better performance sealing product structure, and realized that the life of sealing products can be monitored on the computer, when it should be replaced, clearly.

The life of similar foreign products can only be calculated by formulas, such technology makes the president of the company that once monopolized the industry unable to sit still, and has visited Huaxing Technology Group Company several times, hoping to cooperate, but was politely rejected by Huaxing Technology Group Company.

In the past, the company has also threatened domestic nuclear power plants to purchase the company's other sealing gaskets, or it will not sell the most important sealing rings in nuclear power plants to China.

At that time, no domestic company could produce nuclear sealing rings, and if this company refused to supply them with this threat, it would undoubtedly be a fatal blow to domestic nuclear power plants.

For this reason, China had to swallow its anger and agree to the company's request.

There are two seals in the pressure vessel of a nuclear reactor, and the reactor fuel is changed once a year, and the seals are replaced at the same time.

This kind of sealing ring is leak-proof and radiation-resistant, especially the leakage rate of this sealing ring is extremely high, and the products of Eagle Sauce can leak 5 drops of water in 1 year.

A few years ago, Huaxing Technology Group Co., Ltd. used its own seals in the development of the thorium-based molten salt reactor experimental reactor, which reached the same level as Eagle Sauce.

At present, the design standard of the newly developed seal by the seal technology department is higher, and the degree of leakage of only 2 drops of water in 5 years is stipulated in the nuclear sealing ring, and the sealing ring is now being tested and verified.

In fact, not only the sealing ring, but also the sealing technology department has mastered the graphite sealing plate production technology and the nuclear-grade graphite sealing gasket production technology, which is not even the company of Eagle Sauce.

The year before last, a set of nuclear sealing rings was installed on the reactor pressure vessel of unit 1 of the nuclear power plant for practical use for up to one year, during which the flange sealing layer of the reactor pressure vessel did not leak during operation.

At the end of last year, the reactor was refueled and shut down, and then underwent post-service inspections.

At that time, Zhao Zhizhong and others specially carried out post-service inspection and witness on this set of sealing rings, and through the identification of the expert group, the sealing rings were used for a cycle, and the inner and outer rings were not damaged, the sealing lines were uniform and coherent, and there were no signs of wrinkles and protrusions.

This matter also makes Zhao Zhizhong very happy, and now domestic nuclear power plants are beginning to use the nuclear seal ring produced by Huaxing Technology Group Company to replace imports for nuclear power plant reactor pressure vessels.

This incident also marks that Rabbit has become the second country in the world that can produce nuclear sealing rings, breaking the monopoly of foreign countries for half a century, and realizing the domestic commercial use in a real sense.

This also made the price of similar products of this company of Eagle Sauce drop significantly.

Zhao Zhizhong also has great trust in the technical strength of Huaxing Technology Group Company, and nodded after hearing Yang Jie's words: "As long as Yang Dong agrees." ”

He paused and said: "It is indeed very difficult to manufacture the main pump of the canned unit, and in the previous negotiations, we agreed with the Seibu Nuclear Power Corporation that the main pump of the three units of the four units will be provided by their company, and the main pump of the fourth unit will be localized." After we visited and inspected the main pump factory in Eagle Sauce China, we also realized that the manufacturing process of the shielded main pump is indeed very difficult, and the relevant factories that manufacture the main pump lack the necessary equipment, as well as lack of technical experience and management experience. The person in charge of the main pump contractor company also visited our equipment factory, and they felt that according to the equipment conditions and technical experience of the factory, we could not supply according to the construction schedule. ”

"Damn, this company clearly wants to sell a few more pumps, don't want us to localize, for this we also talked with them for a long time, in order to avoid the risk that our domestic main pump can not be delivered on time, we also agreed to buy another 4 more American main pumps, but at the same time this company must help our domestic factory to manufacture two main pumps on time, as a result, the main pump company in the main pump manufacturing process is a problem, they themselves can not meet the standard. ”

Zhao Zhizhong mentioned this incident and was also angry.

He looked at Yang Jie and said, " Compared with the AP1000 of Seibu Nuclear Power Group Corporation, we have absorbed many experience feedback in the project and the changes in the AP1000 design in the construction process, and have made necessary improvements and upgrades to the original design of AP1000 and the needs of equipment localization. ”

"Now we have determined the design standards, which also meet the technical requirements of the original design of the United States, and now the biggest problem is that it is very difficult to select the materials that meet the standards in China according to this standard, the preparation process and the manufacturing process of these equipment. ”

"Your Huaxing Technology Group Co., Ltd. is the most powerful in China in terms of material research and development and process equipment, and you are also proficient in thorium-based molten salt reactor nuclear power technology. ”

Zhao Zhizhong knew that Ruan Yunfeng's previous work on thorium-based molten salt reactor nuclear power technology had offended Yang Jie, and this matter could only be done by him, the minister of energy, to do Yang Jie's work.
