In South Korea’s KSTAR (Korean Superconducting Tokamak Advanced Research) device, 90WMoNiFe alloy also plays a key role. KSTAR is a superconducting tokamak device dedicated to researching high-temperature plasma physics and nuclear fusion technology. Its goal is to achieve long-term, high-parameter plasma operation to promote the development of nuclear fusion energy.
The application of 90WMoNiFe alloy in KSTAR is mainly reflected in the manufacturing of plasma-facing components. Due to the extremely high temperatures and intense particle flows produced during nuclear fusion reactions, these components need to withstand extreme thermal loads and particle impacts. 90WMoNiFe alloy has become an ideal material for manufacturing these key components due to its excellent high temperature resistance, corrosion resistance and radiation resistance.
Specifically, 90WMoNiFe alloy is used to manufacture components such as the first wall and divertor in KSTAR. The first wall directly faces the plasma and needs to withstand high temperatures and direct impact from particles. The excellent properties of 90WMoNiFe alloy ensure its stability and reliability in this extreme environment. The divertor is responsible for removing impurities and heat from the plasma and maintaining the purity and stability of the plasma. The application of 90WMoNiFe alloy also improves the performance and service life of the divertor.
In addition, 90WMoNiFe alloy may also be used for other structural materials and support components in KSTAR, which also need to withstand the effects of high temperature and radiation. By applying 90WMoNiFe alloy, these components can effectively resist radiation and corrosion while maintaining structural stability, ensuring the overall performance and safety of the KSTAR device.
With the in-depth research of KSTAR and the continuous advancement of technology, the requirements for material performance are also constantly increasing. Therefore, in the future, the 90WMoNiFe alloy may be further optimized and improved according to the specific needs of KSTAR to better meet the needs of nuclear fusion research.
In summary, 90WMoNiFe alloy plays an important role in South Korea’s KSTAR device. Its excellent high temperature resistance, corrosion resistance and radiation resistance make it an ideal choice for plasma-facing components and structural materials.
