In Yang Jie's memories of his previous life, the Shanmen Nuclear Power Plant originally planned that Unit 1 should be completed and put into operation in 2013 as planned. Problems with key equipment such as flywheels, coupled with the fact that the global nuclear power industry has suffered heavy losses after the Fukushima nuclear crisis, and the central government has repeatedly demanded that the safety standards of nuclear power plants be improved, and Toshiba, which acquired the Seibu Nuclear Power Group, is dying, and where is the money to invest in nuclear power research and development, the project has naturally been dragged down, and it has not been put into operation for more than nine years, and finally even the Seibu Nuclear Power Group has collapsed.

Naturally, Yang Jie would not come here to be this god, and he would never mention the matter of this Shanmen Nuclear Power Plant.

As a matter of fact, many people within the nuclear industry group company are also dissatisfied with the establishment of a joint venture between the group company and the Huaxing Science and Technology Group Company, believing that the Huaxing Science and Technology Group is competing with them for credit in coming up with the thorium-based molten salt reactor nuclear power technology at this time.

However, the central government attaches great importance to this matter, and these people do not dare to oppose it openly, and they do not make small reports behind their backs.

However, after the establishment of Huaneng Technology Group Company, because Huaxing Technology Group Company is a major shareholder, and there is strong financial support from Huaxing Technology Group Company behind it, and there is no debt, so the autonomy is still very large.

These things made Huaneng Technology Group Co., Ltd. also breathe a sigh of relief, and the management also assured Yang Jie that this Xiaotangshan Nuclear Power Plant must be used as a model for construction and operation.

Yang Jie is not worried about the operation of the thorium-based molten salt reactor nuclear power plant in Xiaotangshan, because the biggest reliance on his confidence is the advantages of the nuclear power plant technology itself.

Because this set of nuclear power technology itself has natural advantages in terms of safety, and because there is no need for ultra-high pressure vessels and steam generators, the cost and volume of equipment have dropped significantly, and the construction cost has also dropped significantly.

Because Huaneng Technology Group has mastered the preparation and processing technology of special alloy materials for molten core containers and containment vessels and pipeline circuits, and has also established a variety of production lines for the preparation of high-temperature molten salt and high-performance graphite and nuclear pure thorium fuel rods, all the equipment has been localized, although Huaxing Technology Group has invested a lot of money at the beginning, but after the construction of these production lines, the operating cost of thorium-based molten salt reactor nuclear power plants has also been pulled to a very low level.

At present, the average unit investment in the completion price of a second-generation improved nuclear power unit in China is 12,056 yuan per kilowatt, the highest is 12,983 yuan per kilowatt, and the lowest is 10,468 yuan per kilowatt.

Huaneng Technology Group Co., Ltd.'s offer is now cheaper than the cost of the second-generation nuclear power plant, at the level of 8,000 yuan per kilowatt, the investment in the nuclear power plant with a total installed capacity of 2,000 megawatts is only more than 24 billion, which can be said to have created the lowest investment in nuclear power plants.

At the same time, because of the small size of the thorium-based molten salt reactor, the construction time of the project has been shortened to 2 to 3 years, and the construction period of the second-generation reactor is at least 4.5 years.

In the afternoon, with the order of the engineering headquarters, the concrete pouring equipment began to pump the first tank of concrete to the raft foundation of the nuclear island.

This kind of pouring work has been going on for a long time, and Song Xinyang left in a fuel cell bus after inspecting other construction sites, and Yang Jie also left.

The next day, Yang Jie also accompanied Song Xinyang to inspect the Brayton cycle generator technology test base.

Song Xinyang is also very interested in the large-scale supercritical carbon dioxide compressor experimental platform in the base.

"This experimental platform is a general platform for testing the working performance of supercritical carbon dioxide compressors and carrying out basic experiments related to the compression characteristics of supercritical carbon dioxide fluids, and can also be used to carry out experiments such as high-speed rotor testing, bearing testing and seal testing. ”

Gao Shaotong, who was responsible for the development of the Brayton cycle generator system, reported to Song Xinyang at this time.

"You built this platform all yourself?"

Song Xinyang turned his head to look at Yang Jie at this time and asked.

"Most of the compressor general experimental platform we built before was purchased from abroad, but it could no longer meet our R&D experiments, and there was no equipment we needed abroad, so our instrument and equipment company designed and developed such a set of megawatt supercritical carbon dioxide compressor experimental platform. ”

Yang Jie said: "Now this general experimental platform is not only the largest in China, but also the largest and highest level of its kind in the world. ”

"Without this general comprehensive experimental platform, it is difficult for us to achieve high accuracy in the experimental data of the equipment we have developed, which will greatly delay our R&D efficiency. ”

Yang Jie said: "Now with these experimental platforms, these different types of compressors and heat exchangers we have developed can be tested precisely and continuously, and a large amount of data can be obtained, and we can continuously make various improvements according to these data." ”

Song Xinyang looked at Yang Jie and said, "I see that your Huaxing Technology Group attaches great importance to experimental data!"

Yang Jie nodded: "Yes, these experimental data are the most valuable things of our company, through various analysis and mining of these data, we can continuously improve the performance of our company's products and equipment, so that we can design, develop and manufacture better products." ”

Song Xinyang also nodded.

When he learned that the first megawatt supercritical carbon dioxide compressor developed by the Institute of Engineering Thermophysics of the Machine Tool Research Institute has been tested for a long time on this general experimental platform, and a large number of experimental data have been reached, and now the Institute of Engineering Thermophysics has made improvements according to the experimental data.

The compressor is one of the core components of the supercritical carbon dioxide Brayton cycle system, and its successful development can be said to be a major breakthrough in the research field of supercritical carbon dioxide Bretton cycle system in China.

Song Xinyang then inspected another supercritical carbon dioxide heat exchanger comprehensive test platform, which was designed and built by the R&D department of Nanao Group.

A large number of subsidiaries of Huaxing Technology Group are responsible for the development of key equipment for thorium-based molten salt reactors, and these equipment technology patents will be shared by Huaneng Technology Group Company, and then mass production will be completed by the factories of Huaneng Technology Group Company.

Song Xinyang agrees with Yang Jie's R&D model, and the R&D undertaken by many R&D departments of Huaxing Technology Group Co., Ltd. are the areas that these R&D teams are good at, and will not repeat R&D to cause waste, and Huaneng Technology Group Co., Ltd. integrates these most cutting-edge subsystems together, and finally can get the best equipment products.
