As the nuclear power industry continues to evolve, the need for new materials to manage energy release within the active zone of reactors becomes increasingly critical. One promising material in this domain is hafnium wire. This part discusses the potential roles that hafnium wire could play in addressing the challenges of modern nuclear technology.
Hafnium wire emerges as a viable solution due to its high absorption cross-section for thermal and epithermal neutrons, excellent corrosion resistance, strong mechanical properties, and effective heat conduction.
Given its properties, hafnium wire has become an excellent material for regulation rods. These rods are crucial for managing the fission process within a reactor. By using hafnium wire in control rods, reactors can achieve more precise regulation of nuclear reactions, leading to enhanced safety and efficiency.
High-purity hafnium wire can also be used in the emitter material of Compton-type Self-Powered Neutron Detectors (SPND). These detectors are vital for real-time monitoring of neutron flux in a reactor. The application of hafnium wire in SPNDs offers several benefits:
