Market Overview

Neutron absorber materials play a critical role in controlling nuclear reactions by capturing free neutrons and preventing chain reactions. These materials are essential in various nuclear applications including reactor control, radiation shielding, spent fuel storage, and transportation casks. As demand for nuclear energy grows due to its low-carbon footprint, neutron absorber materials are gaining increased attention.

Global neutron absorber material market revenue is projected to grow from USD 183.62 million in 2023 to USD 251.48 million by 2029, registering a CAGR of 5.38% during 2023–2029. This growth is driven by rising investments in nuclear energy infrastructure and innovation in advanced absorber materials.

Key Materials Used in Neutron Absorption

• Boron
  Boron-10, a stable isotope, is a widely used neutron absorber due to its high neutron capture cross-section. It is typically used in control rods and is often incorporated into boron-stainless steel or boron-aluminum composites.

• Cadmium
  Known for its high neutron absorption efficiency, cadmium is commonly used in reactor control rods and as a radiation shielding material.

• Hafnium
  Favored for its excellent corrosion resistance and mechanical strength, hafnium is another key material used in nuclear control rods.

• Silver-Indium-Cadmium (Ag-In-Cd) Alloys
  These alloys offer balanced performance and are often found in neutron absorbing systems.

• Dysprosium
  A rare-earth element used for neutron shielding and control due to its favorable neutron capture properties.

• Samarium
  Especially samarium-149, this isotope is effective in absorbing neutrons and is used in reactor control and neutron poisoning.

• Gadolinium
  Gadolinium-155 is one of the most efficient neutron absorbers and is utilized in burnable poison rods and shields.

• Europium
  Both europium-151 and europium-153 serve as effective absorbers in reactor safety components.
