Application
Pressure Vessels: Used in the construction of reactor pressure vessels that house the nuclear reactor core, where they must withstand high pressure and radiation.
Heat Exchangers: Employed in the manufacturing of heat exchangers, which are critical for transferring heat from the reactor core to the steam generator.
Piping Systems: Used in piping systems that carry coolant and other fluids throughout the nuclear power plant, ensuring safe and efficient operation.
Steam Generators: Utilized in the production of steam generator components that convert water into steam using heat from the reactor core.
Containment Structures: Form part of the containment structures designed to prevent the release of radioactive materials in the event of an accident.
Control Rods and Structural Components: Used in control rods and other structural components within the reactor that require high strength and resistance to neutron radiation.
Reactor Internals: Applied in the fabrication of reactor internals, such as core support structures, which maintain the alignment and stability of fuel assemblies.
