90WMoNiFe alloy has important applications in the International Thermonuclear Experimental Reactor (ITER) project, mainly in the following aspects:
First wall and divertor material facing the plasma
In the ITER device, high-temperature plasma is the core of realizing nuclear fusion reactions. The first wall and divertor are components that directly face these high-temperature plasmas and are subject to extremely high temperatures and strong particle flow impacts. 90WMoNiFe alloy has become an ideal material for these key components due to its excellent high temperature resistance, radiation resistance and good thermal stability. This alloy can effectively resist the high-temperature erosion of plasma and the impact of particle flow, ensuring the stable operation of the device.
thermal structural materials
Thermal structural materials in ITER devices need to withstand high temperatures and strong thermal gradients. 90WMoNiFe alloy’s high melting point, high thermal stability and good mechanical properties make it an excellent choice for these thermal structural components. This alloy maintains structural integrity and stability, preventing deformation or failure in high-temperature environments.
Neutron shielding and radiation protection materials
Nuclear fusion reactions produce large amounts of neutrons and radiation, posing potential threats to surrounding equipment and personnel. Due to its high density and good radiation protection properties, 90WMoNiFe alloy can be used as neutron shielding and radiation protection materials to reduce the harm of radiation to equipment and personnel.
The ITER project is an international cooperation project involving the research, development and application of a variety of materials and technologies. 90WMoNiFe alloy is one of the important materials, and its application may be adjusted and optimized as the plan progresses and technology develops. In addition, the specific application forms of 90WMoNiFe alloy may also include coatings, films, composite materials and other forms to meet the needs of different components in the ITER device.
In summary, 90WMoNiFe alloy plays an important role in the International Thermonuclear Fusion Experimental Reactor Program. Its excellent high temperature resistance, radiation resistance, thermal stability and mechanical properties contribute to the stable operation of the device and the realization of nuclear fusion reactions. Provides strong protection.
