I Advanced Reactor Technologies: Small Modular Reactors (SMRs) and Generation IV Reactors
I1. Small Modular Reactors (SMRs)
SMRs are the next generation of nuclear reactors, featuring size and scalability that allows them to be built as individual power plants or added in modules to larger facilities. With a capacity of up to 300 MW, they offer safety and efficiency advantages over traditional reactors due to their smaller scale, making them an attractive option for countries seeking nuclear energy expansion. Additionally, SMRs offer flexibility in deployment, as they can be used to meet various power demands and grid requirements.
I2. China’s efforts in developing SMRs
China has been actively investing in the development of SMRs, with multiple projects and partnerships underway. For instance, the Hualong One design by China National Nuclear Corporation (CNNC) is a 60 MW pressurized water reactor that has been successfully exported to Argentina. Furthermore, CNNC has entered into partnerships with Russia’s Rosatom and South Korea’s Kepco to jointly develop SMR technologies.
I2. Generation IV Reactors
Generation IV reactors represent the next evolution in nuclear technology, offering potential benefits through the use of advanced fuel types
Molten Salt Reactors (MSRs)
such as Molten Salt Reactors (MSRs), which can process a wide range of fuel types, including spent nuclear fuel and thorium.
Additionally, Generation IV reactors offer enhanced safety features
Passive Safety Systems
and passive safety systems that rely on natural processes to maintain stability, as well as increased efficiency and reduced waste production.

Additionally, China is involved in the International Generation IV Power System Project, a collaborative effort between several countries to develop next-generation nuclear technology.
Nuclear Waste Management and Decommissioning
The Challenge of Nuclear Waste Management and Decommissioning
Nuclear energy, a low-carbon source of electricity, plays an essential role in many countries’ energy mixes. However, the industry poses unique challenges when it comes to nuclear waste management and decommissioning. These tasks are complex, expensive, and time-consuming.
Environmental Concerns
The safe disposal of nuclear waste is a major environmental concern. High-level radioactive waste remains dangerous and requires secure, isolated storage for thousands of years. The potential consequences of mishandling this waste can be catastrophic.
Financial Implications
The financial implications of nuclear waste management and decommissioning are substantial. The costs can include site preparation, containment systems, monitoring, and long-term maintenance. Additionally, these expenses often fall on the taxpayer or utility ratepayers, leading to public skepticism.
China’s Innovative Approaches to Address These Challenges
Despite these challenges, countries are exploring new approaches to address nuclear waste management and decommissioning. One such innovator is China.
Advanced Waste Disposal Techniques
China is investing in advanced waste disposal techniques, such as deep geological storage and vitrification. Deep geological storage involves burying waste in stable underground formations, while vitrification is a process that converts high-level waste into glass logs for disposal.
Public-Private Partnerships and Collaborations for Decommissioning Projects
Another approach China is taking is fostering public-private partnerships and collaborations for decommissioning projects. This approach helps share the risks and costs between government, utility companies, and private contractors.
Global Implications of China’s Advancements in Nuclear Waste Management and Decommissioning
China’s advancements in nuclear waste management and decommissioning have global implications. If successful, these approaches could pave the way for other countries to develop similar strategies. This could help address environmental concerns and reduce financial burdens associated with nuclear waste management and decommissioning.
Nuclear Fusion: China’s Ambitious Pursuit
Nuclear fusion, the process that powers the sun and stars, is a promising source of clean energy with minimal waste generation and zero greenhouse gas emissions. Unlike nuclear link, which splits atomic nuclei to release energy, fusion joins lighter nuclei together. The potential benefits of nuclear fusion are significant: it would provide a virtually endless energy source and significantly reduce carbon emissions from the power sector.
China’s Investment and Progress in Nuclear Fusion Research
China, the world’s largest emitter of greenhouse gases, has made ambitious investments in nuclear fusion research. The country aims to become a global leader in this field and reduce its reliance on fossil fuels. One of China’s most significant advancements is the
Experimental Advanced Superconducting Tokamak (EAST)
.
The Experimental Advanced Superconducting Tokamak (EAST)
EAST, located in Hefei, China, is a link-type fusion reactor. It uses powerful magnetic fields to contain and heat plasma, which is then manipulated to achieve sustained nuclear fusion reactions. EAST has achieved several notable milestones:
Achievements
- Reached plasma temperatures of over 120 million degrees Celsius, the highest ever in an experimental fusion reactor outside the US and Europe
- Achieved a plasma duration of 102 seconds, which is longer than any other Chinese fusion reactor experiment
These achievements demonstrate China’s growing prowess in nuclear fusion research and its potential to contribute significantly to the global nuclear power landscape. However, challenges remain.
Challenges and Future Prospects of Nuclear Fusion in China and Globally
While the progress in nuclear fusion research is promising, there are significant challenges to overcome. These include:
Scaling up the technology and making it economically viable
Developing advanced materials that can withstand the extreme conditions inside a fusion reactor
Addressing tritium production and handling, as it is a vital fuel for fusion reactions but also highly radioactive and challenging to produce
Despite these challenges, the future looks bright for nuclear fusion. China will continue to invest in research and development, working towards a commercially viable fusion power plant. Additionally, international collaboration and the sharing of knowledge and resources will be essential to advancing this technology.
