Because of the low power density of high-temperature gas-cooled reactors, the power of traditional nuclear power plants can easily reach gigawatts in the main plant of the same size nuclear island, while high-temperature gas-cooled reactors can only achieve 100 megawatts to 200 megawatts, which is a bit embarrassing.

The size of the thorium-based molten salt reactor with the same thermal power is less than half of that of the traditional pressurized water reactor reactor, and it is atmospheric pressure, although the requirements for the materials of the container and pipeline themselves are very high, but the processing technology is not very difficult.

Because this molten salt reactor does not have the risk of core melting and explosion, coupled with its small size, the containment can be made very thin and small, so the cost is very advantageous.

Yang Jie picked up a big bargain in thorium-based molten salt reactor reactor technology, when he took over the company Gela Energy Technology Company, the company was actually mature in the second-generation technology, and the largest investment was in the construction of the third-generation thorium-based molten salt reactor experimental reactor in China and the establishment of a domestic supply chain, as well as the technical research and development of supporting facilities such as carbon dioxide supercritical generator sets and high-temperature electrolysis hydrogen production equipment.

These technologies began to lay out in this area after Yang Jie took over the Gaila Energy Technology Company, and now they are gradually maturing, because Huaxing Technology Group has a large number of key technologies in its own hands, and the key equipment can also be built by itself, and there will be no situation where suppliers ask for sky-high prices.

Yang Jie is also willing to invest in large projects such as nuclear power projects to drive the development of the entire industry, but to reduce the cost of thorium-based molten salt reactor nuclear power plants rapidly.

Unisplendour University has been continuously developing high-temperature gas-cooled reactor technology for more than 30 years, and now the technology has matured, but because of the low power density, if it is only used to generate electricity, the economic benefits generated are not even as good as those of the second-generation nuclear power plant, and the biggest advantage is to use the high temperature of the reactor to prepare hydrogen and other supporting industries.

Of course, thorium-based molten salt reactor nuclear power plants can also do what high-temperature gas-cooled reactors can do, and the economic benefits are higher because of the very high power density.

The state has been investing in research and development of high-temperature gas-cooled reactor technology for so many years, and this technology is now mature, and it is impossible to give it up now.

Ziguang University also knows that high-temperature gas-cooled reactors have little advantage in power generation, so they have begun to lay out high-temperature electrolysis hydrogen production projects very early, but the progress is not as fast as Huaxing Technology Group Company, and now Huaxing Technology Group Company's high-temperature electrolysis hydrogen production equipment has been put into operation at Xiaotangshan Nuclear Power Plant.

Although the power density of high-temperature gas-cooled reactors is low, the economic benefits generated by supporting hydrogen production and other projects will not be lower than those of third-generation nuclear power plants, after all, the main operating cost of nuclear power plants is nuclear fuel, because of the mastery of the preparation process of nuclear fuel balls, domestic can be prepared in large quantities, plus these nuclear fuel balls will not produce a large amount of high-radioactive waste like traditional nuclear power plants after being used up in the core, because the fission products are sealed in the sphere.

These "burned" balls only need to be sealed in special containers, and the cost of nuclear waste disposal is much lower than that of traditional pressurized water reactor nuclear power plants.

In all respects, the economic benefits of high-temperature gas-cooled reactors are not lower than those of third-generation nuclear power plants.

Of course, in order for high-temperature gas-cooled reactors to form an industrial scale, it is necessary to build several more nuclear power plants in order to give full play to the economies of scale.

Now there are two fourth-generation nuclear power technologies in China, and they are all mature, and the enthusiasm of the high-level for the third-generation nuclear power technology is not very large, but the country has spent a lot of money to introduce the third-generation nuclear power technology, and the third-generation nuclear power plant that was planned and built before still has to be built, otherwise it will be a big loss.

Yang Jie was basically silent when he saw Ruan Yunfeng coming over and sitting there this time, but he would not hold on to the previous matter, after all, the two sides were not mortal enemies.

A few days later, Yang Jie came to visit the North Nuclear Fuel Element Co., Ltd. in Qingshan District, Baotu City.

The company is a state-owned enterprise with more than 50 years, has made important contributions to the country's "two bombs and one boat" and nuclear power industry, is China's first nuclear fuel element plant, and is now also the domestic nuclear fuel element with the largest variety of types, the most complete technical route of the production supplier, with heavy water reactor, pressurized water reactor, thorium-based molten salt reactor and high-temperature gas-cooled reactor and other nuclear power fuel element production lines.

Huaneng Nuclear Power Technology Group Co., Ltd. has its own experimental production line to trial produce and test molten salt nuclear fuel, but mass production, especially uranium tetrafluoride and thorium tetrafluoride in molten salt mixtures, is in great demand, and can only be provided by North Nuclear Fuel Co., Ltd.

Executives from the Northern Nuclear Fuel Co., Ltd. and personnel from the Huaneng Nuclear Power Technology Group Company accompanied Yang Jie to the outside of the plant specializing in the production of molten salt nuclear fuel.

When entering the workshop, Yang Jie also wore a U-disk type accessory on his chest, which is a radiation meter, which contains special crystals that can absorb all kinds of rays emitted by the material, so as to determine whether the radiation dose received by the production personnel exceeds the standard.

Entering the nuclear fuel element production workshop, Yang Jie also noticed that the front-line staff were only wearing an ordinary work clothes.

"Yang Dong, in the preparation process of nuclear fuel elements, just like the raw coal that has just been mined, there is no fission reaction, it is a weak radioactive substance, and a piece of paper can block the rays released by the material, so there is no need to wear radiation protective clothing. ”

The person in charge of the molten salt reactor nuclear fuel element production line explained to Yang Jie at this time.

However, in order to minimize the number of times workers have direct contact with production materials, this production workshop uses automated assembly lines and a large number of robots. ”

Yang Jie nodded, he only saw a few staff when he visited the production workshop, and the robotic arm produced by Chenxi Machinery Factory could be seen at different process nodes to transfer or grab these materials.

The raw materials produced by the nuclear pure thorium production line built by Huaxinke Group in Baotu City will be sent here for processing again to prepare high-purity thorium tetrafluoride compounds, and the production process is fully automated, and the efficiency is very high.

In order to provide molten salt for more reactors at Xiaotangshan Nuclear Power Plant and Jiangchang Nuclear Power Plant, North Nuclear Fuel Co., Ltd. and Huaneng Nuclear Power Technology Group Co., Ltd. have cooperated, and the former has also been scaled up according to the molten salt production process provided by Geira Energy Technology Co., Ltd. according to the experimental production line, which can now meet the needs of Huaneng Nuclear Power Technology Group's thorium-based molten salt reactor for molten salt nuclear fuel.

Yang Jie then also visited the production workshop of the secondary neutron source module developed by North Nuclear Fuel Co., Ltd. for thorium-based molten salt reactors.

Because the temperature of the molten salt reactor is very high, and the molten salt is very corrosive, the neutron source components need to be redesigned and developed.

After more than two years of hard work and preparation, Yang Jie finally designed and developed this set of neutron source components and a complete set of equipment tooling, and the neutron source components and installation of the laboratory and the No. 1 unit of the Xiaotangshan Nuclear Power Plant were also completed by the engineering and technical personnel of the North Nuclear Fuel Co., Ltd.
