I. Evolution of nuclear waste
1. The transmutation of nuclear waste is the most important function of Venus II and its core goal. Venus II is an accelerator-driven subcritical system (ADS), which can use spallation neutrons produced by high-energy proton accelerators to drive subcritical fast neutron reactors, thus realizing the proliferation of nuclear fuel and the transmutation of nuclear waste.
2. Transmutation is to transform long-lived high-level radioactive waste into short-lived low-level radioactive waste, thus reducing the quantity, volume and harm of nuclear waste and solving the problem of "safe disposal of nuclear waste".
Second, the proliferation of nuclear fuel.
1, Venus II can use the proliferation effect of fast neutron reactor to transfer non-fissile nuclides such as uranium 238? Convert it into fissionable nuclide, such as plutonium -239, so as to improve the utilization and supply of nuclear fuel, prolong the life of nuclear energy resources and realize the large-scale sustainable development of nuclear energy.
2. With solid uranium rods with different concentrations as nuclear fuel and water or lead as medium, Venus II can carry out experimental research on various reactor physical parameters and models, and provide technical support for fast neutron reactors and closed fuel cycles.
Training personnel and training materials
1, training talents
Cultivating talents is the auxiliary function of Qixing II and its social benefit. Qimingxing-2 is the breakthrough of key technologies in innovative research and development of China's lead-based heavy metal-cooled fast neutron reactor, which indicates that China has reached the international advanced level in ADS research and zero-power device research and development.
2. Training materials
Venus II can be used as a multifunctional experimental research platform for reactor physics, providing opportunities for education and training, scientific exchange, cooperation and innovation for scientists, engineers, teachers and students engaged in ADS-related fields at home and abroad, and promoting the cultivation and development of nuclear energy science and technology talents.
The above is a list of the functions of Venus II that I recommend. Of course, there are many other functions and meanings. The key is to understand the principle and purpose of this device, as well as its contribution to the nuclear energy industry in China and the world.
