China - fast plans
AtomInfo.Ru, PUBLISHED 26.04.2022
The FR22 International Conference on Fast Reactors and Associated Fuel Cycles was held at the IAEA Headquarters in Vienna from 19 to 22 April 2022.
Yang Hongyi from China Atomic Energy Institute CIAE gave a presentation on the current state of China's fast program.
At present, PWR light water reactors are the backbone of China's nuclear power industry. At the next stage of development, fast reactors should appear in the country, and fusion energy will become the third stage. In parallel with the development of reactor technologies, the development of the necessary fuel cycles is underway.
The tasks of fast reactors in China include increasing the efficiency of using uranium resources and transmuting long-lived radioactive materials.
China operates an experimental fast sodium reactor CEFR. The construction of two demonstration power units with fast sodium reactors CFR600 is also underway (commissioning will be completed approximately in 2025).
Further, approximately in the period 2030-2035, a commercial fast sodium reactor CFR1000 should appear in the country.
In parallel, projects for fast small modular reactors are being developed in China. The main efforts are focused on a fast sodium SMR project with a capacity of 1 to 3 MWe for power supply to remote areas.
In addition, a project is being developed for a small modular reactor with a capacity of 1 MWe with a lead-based coolant as lead-bismuth is often referred to in China. At the same time, an appropriate amount of R&D on materials, physics and components is carried out for it.
Under the CiADS (accelerator controlled subcritical reactors) project, a 7.5 MWt subcritical fast reactor with a lead-based coolant is planned to be built in Guangdong.
This is the first and only operating pressurized boiling reactor with natural coolant circulation in the country.
Four candidate sites are currently being explored.
Small Modular Reactors Day was an international platform for discussing the benefits of SMR.
