According to the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences, after 15 years of exploration, China's nuclear-grade steel has made a breakthrough and is generally considered to be the preferred structural material
for future nuclear fusion demonstration reactors and the first commercial nuclear fusion power station.
Recently, the Institute of Nuclear Energy Safety Technology of the Hefei Institute of Physical Sciences, Chinese Academy of Sciences, cooperated with domestic special steel enterprises to successfully realize the industrial-scale mass production
of low-activation martensitic steel (CLAM) in China.
On September 8, the official website of the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences announced that the successful preparation of 6-ton CLAM steel marked that China has broken through the technical bottleneck of industrial production of low-activated ferrite/martensitic (RAFM) steel for fusion reactors, and reached the international advanced level
in the large-scale preparation of low-activation steel.
Low-activation steel is a high-purity nuclear-grade material, which is widely regarded as the preferred structural material
for future fusion demonstration reactors and the first commercial fusion power station due to its good resistance to neutron irradiation and low activation characteristics and relatively mature industrial technology base.
A fusion demonstration reactor requires approximately 3,500 tonnes of low-activated steel, so smelting scale is one of the key questions for industrial applications of
low-activated steel.
In order to meet the construction needs of the International Thermonuclear Experimental Reactor (ITER) and the Future Fusion Power Demonstration Reactor, ITER participants such as the European Union, Japan and China have carried out industrial-scale research and development of RAFM steel
.
At present, the power generation technology of nuclear power plants in the world is mainly nuclear fission
.
Scientists say that although nuclear fission can produce huge energy, but far less than nuclear fusion, the fission reactor nuclear fuel reserves are extremely limited, not only produce powerful radiation, harm the human body, but also the waste left behind for thousands of years is also difficult to dispose of, nuclear fusion radiation is much less, nuclear fusion fuel can be said to be inexhaustible
