China has achieved a significant milestone in its pursuit of advanced nuclear technologies by launching its first thorium reactor.
The South China Morning Post reports that this two-megawatt liquid-fueled thorium molten salt reactor (MSR) represents a significant step forward in China's nuclear energy sector.
Located in Wuwei, Gansu province, the reactor is operated by the Shanghai Institute of Applied Physics, Chinese Academy of Sciences.
With China's National Nuclear Safety Administration issuing an operational permit, the Shanghai Institute is set to test the reactor's operations over the next decade.
Advantages of Thorium Reactors
Thorium MSRs offer a host of advantages over traditional uranium reactors, making them an attractive option for the future of nuclear power.
These reactors use liquid fuels, typically molten salts, as both fuel and coolant. One of the key benefits is increased safety, as the liquid fuel's properties reduce the risk of overheating and meltdown.
Additionally, thorium reactors produce reduced waste and demonstrate improved fuel efficiency, maximizing the use of available resources.
Furthermore, thorium offers a potentially abundant and sustainable long-term energy alternative, with an average thorium concentration of 10.5 parts per million in the Earth's upper crust, compared to 3 parts per million for uranium.

China's Progress in Advanced Nuclear Technology
China declared the completion of its first experimental thorium-based nuclear reactor in August 2021, and the country has come a long way since then. Last month, China's environment agencies greenlighted its first thorium molten salt reactor.
Experts in China's nuclear industry laud the launch of the thorium reactor as a significant achievement, positioning China as a potential leader in thorium reactor technology.
The Shanghai Institute has also unveiled plans for a small-scale modular thorium MSR research facility, aiming to address technical challenges and further advance the technology.
Small-scale modular reactors offer flexibility, enhanced safety features, and cost-effectiveness, making them an appealing option for energy production.
China's Thorium Reserves and Inland Energy Potential
SCMP notes that China possesses one of the world's largest thorium reserves, estimated to meet the country's energy needs for over 20,000 years.
The abundance of this resource presents an opportunity for China to expand its nuclear energy supply to inland cities.
Thorium MSRs offer the flexibility to establish nuclear power plants in regions far from coastal areas, diversifying the energy mix and reducing dependence on fossil fuels.
Furthermore, the use of molten salts as fuel and coolant reduces the reliance on water, making these reactors suitable for areas with limited water resources.
International Implications
China's advancements in thorium reactor technology have broader implications for the global energy sector.
The potential to deploy large-scale thorium reactors could enhance China's competitiveness, strengthen energy security, and contribute to environmental sustainability.
Additionally, China aims to sell small thorium reactors to other countries as part of its Belt and Road Initiative.
These reactors, with their smaller capacity and modular design, provide a viable and accessible nuclear energy option for countries with smaller energy demands or limited grid infrastructure.
