[China / CNIPA Application # 2022800612462]
An introduction of nuclear fusion into conventionally fission-based nuclear reactors. Particularly, coolant in the reactor serves as the secondary fuel that absorbs neutrons from the fission core, and releases energy through fusion reactions. Molten Lithium is the preferred coolant in the invention, as it produces Helium gas through the neutron-Lithium fusion without leaving any radioactive or chemical impact to the environment. A Helium pressure controller is also introduced in the system to manage the Helium gas produced by nuclear reactions of the secondary fuel. Lithium Chloride (LiCl) is proposed as the secondary coolant in lieu of the commonly used molten salt in order to achieve higher power production efficiency. A reactor based on the proposed system requires less space than a conventional reactor of the same power. It is a better choice than conventional nuclear reactors when space is a key constraint, for example, on a container ship.

Financial information

Summary of Potential Benefits
1. Increases energy production by ~20% relative to fission reaction alone.
2. Cleans up neutrons from fission reaction, produces only Helium-4.
3. Operates at higher operation temperature, hence higher power production efficiency.

Size of Opportunity
1. The size of the nuclear energy market in China was valued at USD 34.72 billion in 2022. It is anticipated to grow robustly in the forecast period with a compound annual growth rate (CAGR) of 3.6% through 2028. This growth reflects China’s ongoing commitment to expanding its nuclear energy capabilities and infrastructure.
2. From another perspective, nuclear energy accounted for 5% of China’s total electricity generation since 2021, and is expected to grow while the coal based electricity generation (currently at ~63%) is reduced in the next decade.
3. As a comparison, nuclear power plants have provided around 19%–20% of the US electricity since the 1990's. In terms of clean energy, nuclear energy contributed 47% of America’s carbon-free electricity in 2022, making it the largest domestic source of clean energy.
