"We Huaxing Technology Group Co., Ltd. to develop these key equipment has no problem, but this AP1000 is always the technology of Eagle Sauce, and can only be built in China, compared to the second generation of nuclear power technology, the cost of this third generation of nuclear power technology is still too expensive, even if the nuclear power technology company has developed its own third-generation nuclear power technology on this basis, all the equipment is localized, but the cost is still high, and the export overseas has to compete with Gallic chickens and big hairy countries, and the difficulty is not small. ”

Yang Jie opened his mouth and said.

"Your worries are indeed justified, and now our domestic sources of third-generation nuclear power technology mainly come from Eagle Sauce and France, Da Naga, and Da Mao, and it is very troublesome for these different nuclear power technology solutions to be integrated together. ”

Zhao Zhizhong nodded.

"The design standards of the third generation of nuclear power technology are much higher than the second generation of nuclear power technology, the eagle sauce wants to launch the third generation of nuclear power project cost is expected to be about 30,000 yuan per kilowatt, now look at this situation may be higher, and the third generation of the Gallic chicken in their own country on the third generation of nuclear power plant cost in 20,000 yuan per kilowatt, last year this project also occurred serious quality problems, it is estimated that the cost will be increased again, they helped Finland to build the third generation of nuclear power plant construction in the construction of many quality accidents and design problems, many delays, the cost increased to 28,000 yuan per kilowatt levelEven if all the domestic cost in our country is at most, the cost can only be controlled at 15,000. ”

Yang Jie said: "Even if it is this cost, many countries want to introduce and build it, and this third-generation nuclear power plant also involves nuclear proliferation problems, and it is not easy to export this nuclear power technology." ”

"Yes, the best choice for the nuclear power technology suitable for export in China is the two fourth-generation nuclear power technologies that we have mastered in China, one is the thorium-based molten salt reactor technology of Huaneng Nuclear Power Technology Group, and the other is the high-temperature gas-cooled reactor nuclear power technology of Ziguang University, both of which cannot be used by other countries to manufacture nuclear weapons, and the safety is much higher than that of the third-generation nuclear power technology. ”

Tu Jianfeng spoke.

Ruan Yunfeng glanced at Tu Jianfeng at this time, his expression was a little complicated.

The Nuclear Industry Corporation is the oldest nuclear industry company, and the Southern Nuclear Power Corporation and the Nuclear Power Technology Corporation are both separated from the Nuclear Industry Corporation, and the Nuclear Industry Corporation has previously built several nuclear power plants in China through cooperation with Da Mao and the Danaca countries, and has also developed its own third-generation nuclear power technology, and its nuclear technology capabilities are stronger than those of the Nuclear Power Technology Company.

The Southern Nuclear Power Group Company has introduced the nuclear power technology of Gallic chickens and built a number of nuclear power plants, and its technical and economic strength is also very strong.

At this stage, the nuclear power technology of the nuclear power technology company comes from Eagle Sauce, because the nuclear power plant project is blocked, and the strength is the weakest.

There are many similarities between these three group companies in nuclear power technology, but they are the most competitive.

Huaneng Nuclear Power Technology Group Co., Ltd. is a joint venture between Huaxing Science and Technology Group Co., Ltd., Nuclear Industry Group and Nanfang Nuclear Power Group Co., Ltd., which takes the route of fourth-generation nuclear power technology, and is mainly exported.

Ruan Yunfeng knows that the Nuclear Industry Corporation and Unigroup University have always cooperated in high-temperature gas-cooled reactor nuclear power technology, and now that Tu Jianfeng has proposed to include high-temperature gas-cooled reactor nuclear power technology in export projects, he is naturally wary.

This year, Huaneng Nuclear Power Technology Group Corporation won a project to design and build a thorium-based molten salt reactor nuclear power plant in Bosai country, and at the same time, he also heard the rumor that the emirate intends to introduce nuclear power projects, and the nuclear power technology company is not envious of such a thing.

A few years ago, the central government established a nuclear power technology company, and paid special attention to the third-generation nuclear power technology of Eagle Sauce, Ruan Yunfeng felt very good at that time, but he did not expect that in the past few years, the third-generation nuclear power technology of these state-owned nuclear power enterprises was not very popular.

At present, both the Nuclear Industry Group and the Southern Nuclear Power Group Corporation have launched the technology research and development project of thorium-based molten salt reactor nuclear power plant.

Last year, the nuclear power technology company also established a technology research and development center for cooperative research and development of high-temperature gas-cooled reactors with Ziguang University, and also began to lay out the nuclear power technology of high-temperature gas-cooled reactors.

Yang Jie didn't say much about high-temperature gas-cooled reactor nuclear power technology, but it doesn't mean that he didn't know about this fourth-generation nuclear power technology.

At the end of the 70s of the last century, Ziguang University sent scholars and students to West Germany to participate in the research and development of high-temperature gas-cooled reactors, but this experimental reactor had a small accident in 88 years, the fuel ball was stuck at the exit, and the fuel ball broke during processing, resulting in the release of a small amount of radioactive fallout.

However, after the closure of the experimental reactor, Unigroup University bought back the intellectual property rights and drawings of the experimental reactor at a very low price, and brought back the production line of fuel balls to China.

Unigroup University built a low-power high-temperature gas-cooled reactor very early to conduct a large number of experiments, and made a lot of technological breakthroughs in 94 years, and built a 10-megawatt experimental reactor in the second year, and built a grid-connected power generation in 2,000 years.

In 05, the demonstration reactor of the commercial version of Ziguang University was also selected in Shidao Bay, Qilu Province, but the main source of funds for this project still depends on the support of the national finance, although the state will include the high-temperature gas-cooled reactor nuclear power plant demonstration project in the national science and technology major projects, but the central government has to take care of the three national nuclear power enterprises, the allocated funds are not too much, and the progress of the project is still relatively slow.

Huaneng Nuclear Power Technology Group Co., Ltd. is different, because the funds, personnel and equipment are in place very quickly, and the demonstration project of Xiaotangshan Nuclear Power Plant is quickly carried out.

Compared with thorium-based molten salt reactor nuclear power technology, high-temperature gas-cooled reactor reactors still require high-pressure vessels, and the container is larger than the container volume of pressurized water reactors, because the size of the reactor is 30 times larger than that of pressurized water reactors, and naturally high-pressure vessels have to be made large.

The structure of a high-temperature gas-cooled reactor is simple, basically a large hourglass with hundreds of thousands of fuel balls, no neutron moderator, no neutron absorption rod, and no need to use a mechanical device in the furnace core. This is because all the functions are concentrated on the fuel balls themselves, the shutdown is based on physical properties rather than engineering, and the cooling loop uses helium, which has zero corrosivity and radioactive absorption.

The most critical technology of this nuclear power technology is still focused on the development of the fuel balls themselves, and different high-temperature gas-cooled reactors determine how many fuel balls to put according to the design power requirements.

These fuel balls are about the size of a tennis ball, with a thin layer of reinforced graphite at the outermost layer, and a filling made up of thousands of fuel pellets mixed with graphite.

Ziguang University has been developing fuel balls for many years, especially in the preparation process of nuclear fuel balls, and Huaxing Technology Group has also made a lot of efforts in this middle.
