FAQS

Why is hafnium used in control rods?

Hafnium is used in control rods for several key reasons:

1. Neutron Absorption
Hafnium has a high neutron capture cross section, which means it is very efficient at absorbing neutrons. This property is crucial for controlling the rate of nuclear fission in a reactor.

2. Stability at high temperatures
Hafnium maintains its structural integrity and performance at the high temperatures common in nuclear reactors, making it a reliable choice for control rods.

3. Corrosion Resistance
Hafnium has excellent corrosion resistance, which is very important in the harsh chemical environment of nuclear reactors. This helps ensure the longevity and effectiveness of the control rods.

4. Low reactivity
Hafnium is relatively inert, minimizing the risk of adverse chemical reactions that could compromise reactor safety.

Is hafnium radioactive?

Hafnium is not radioactive. It is a stable element and does not contain isotopes considered radioactive. The most common isotope of hafnium is hafnium-178, which is stable and does not undergo radioactive decay.
