1. Breakthrough in thorium-based molten salt reactor technology
1. What is a thorium-based molten salt reactor?
A thorium-based molten salt reactor, as the name suggests, is a type of nuclear energy reactor that uses thorium as a fuel and coolant in that it uses molten thorium fluoride salts as fuel and coolant. Compared with traditional heavy water reactors and light water reactors, thorium-based molten salt reactors have higher fuel utilization rate and better safety performance, and can also realize fuel recycling and reduce the generation of nuclear waste.
2. Why choose a thorium-based molten salt reactor?
The thorium-based molten salt reactor has attracted much attention mainly because of its advantages in the following aspects:
- Thorium is abundant: Thorium is a radioactive element that is widely present in the earth's crust and is more abundant than spent fuel to meet long-term energy needs.
- Lower pressure: Thorium-based molten salt reactors operate at atmospheric pressure and have lower pressures than pressurized and boiling water reactors, reducing the complexity of auxiliary systems and improving safety.
- **Good Thermal Conductivity**: Molten salt has good thermal conductivity, which can effectively convert nuclear energy into heat energy, improving thermal efficiency.
- **Green environmental protection**: The fuel used in molten salt reactors can realize fuel recycling, reduce the generation of nuclear waste, and at the same time, it can also use thorium resources, which has good environmental benefits.
3. The impact of technological breakthroughs
The breakthrough of thorium-based molten salt reactor technology will have a profound impact on human society:
- **To meet long-term energy needs**: The emergence of thorium-based molten salt reactors means that human beings are expected to use abundant thorium resources to meet energy needs for tens of thousands of years, providing strong support for the sustainable development of human society.
- **Promoting the Energy Revolution**: As a clean and efficient form of energy, thorium-based molten salt reactors are expected to become an important part of the future energy structure, promoting the transformation of human society to clean energy and realizing the energy revolution.
- **Changing the geopolitical landscape**: Breakthroughs in thorium-based molten salt reactor technology will redefine the strategic position of energy and may have a profound impact on the global geopolitical landscape, and countries involved will reassess their energy strategies.
Second, the first-mover advantage of the eastern powers

With abundant thorium resource reserves and advanced scientific research strength, the eastern country has made a major breakthrough in the research and application of thorium-based molten salt reactor technology, and plans to start construction of the world's first thorium-based molten salt reactor nuclear power plant in 2025, which will be the first engineering application of thorium-based molten salt reactor technology, marking an important step in the field of clean energy in the eastern country.
3 Challenges and prospects of thorium-based molten salt reactor technology
1. Challenges
Despite the many advantages of thorium-based molten salt reactor technology, there are still many challenges in order to realize its engineering application, mainly focusing on the following aspects:
- **High temperature material selection**: The high working temperature of molten salt reactor puts forward higher requirements for structural materials, and how to choose structural materials that can withstand high temperature corrosion is an urgent problem to be solved.
- **Molten Salt Chemical Control**: The molten salt in the molten salt pile is highly corrosive, and how to effectively control the chemical properties of molten salt and prevent corrosion and damage of materials is a technical difficulty.
- **Nuclear waste reprocessing**: Although molten salt reactors can reduce the generation of nuclear waste, there will still be a small amount of nuclear waste, and how to carry out effective reprocessing and disposal is an issue that needs to be studied in depth.
2. Bright prospects
Despite the challenges, people are confident in the prospects of thorium-based molten salt reactor technology, believing that it has great application potential and development space:
- **High safety**: Compared to traditional nuclear energy reactors, molten salt reactors have better inherent safety and can automatically adjust nuclear reactions in the event of an accident, reducing the likelihood of accidents.
- **High thermal efficiency**: Molten salt reactors can work at higher temperatures and have high thermal efficiency, which can provide sufficient heat energy for industrial production and domestic heating.
- **Good environmental protection**: molten salt reactors can realize fuel recycling, reduce the long-term storage of nuclear waste, and at the same time, can also use thorium resources, which has good environmental benefits.
3. The importance of international cooperation
In the face of common energy challenges, the international community should strengthen cooperation and jointly promote the research, development and application of thorium-based molten salt reactor technology, so as to achieve sustainable use of energy and contribute to the sustainable development of human society. As the pioneers of thorium-based molten salt reactor technology, the eastern powers should make full use of their own advantages, actively participate in international cooperation, promote the international standardization and normalization of technology, and make positive contributions to global energy governance.
