Concrete as neutron shielding

In many sectors of the nuclear industry, the widely used neutron shielding is concrete. The main requirements, as set for concrete structures in the nuclear industry are:

  • Radiation protection
  • Structural integrity
  • Durability of radiation shielding

Nuclear power plants use heavyweight concrete for shielding

Our customers use MagnaDense as radiation protection in nuclear buildings for many years now. When used MagnaDense as a concrete aggregate, the heavy concrete can achieve densities of up to 4.0 t/m³. Standard concrete typically has a density of up to 2.4 t/m³.

High-density concrete provides excellent protection from harmful radiation and generated heat. Additionally, the concrete’s structure is superior and has higher durability and in relation to composite lead or steel shields, it is cheaper as well.

Storage and transportation of nuclear waste

When dismantling nuclear power plants waste materials need to be carefully stored either in concrete bunkers and/or by encapsulation. The addition of MagnaDense to the concrete enables slimmer bunkers or containers so less concrete is required, thus decreasing overall construction costs. When used for transportation containers MagnaDense can assist to make the container smaller in dimension and therefore easier to handle but with the same safe shielding properties as thicker normal concrete.

MagnaDense is a natural mineral which will remain stable under long-term storage conditions which is an essential consideration for nuclear-decommissioning projects.

Economic advantages of using MagnaDense for nuclear shielding

As a construction material for new nuclear power plants, nuclear testing facilities or nuclear waste confinements, MagnaDense provides the following benefits:

  • Good radiation shielding characteristics
  • Strength of high-density concrete
  • Resistance to damage
  • Thermal properties
  • Cost efficiency
  • Space Saving

Nuclear radiation experience

LKAB Minerals has done more projects for nuclear radiation shielding that include MagnaDense than can be presented online. Many projects have been gathered in our radiation shielding project brochure which is available by contacting our sales managers via the contact field at the bottom of this page. We also have a specific Case Study on Nuclear Waste Containers made with high density concrete which is available for free, just contact us!

Through years of experience, LKAB Minerals knows that MagnaDense is a perfect match for radiation shielding projects.
