Nuclear shielding against radiation leakage with MagnaDense

High-density MagnaDense concrete is commonly used as a shielding material to provide protection against the hazard of nuclear radiation leakage.

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

MagnaDense has been used in nuclear buildings for many years now. When MagnaDense is used 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 shielding 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.

Heavy concrete for storage and transportation of nuclear waste

When nuclear power plants are dismantled waste materials need to be carefully stored either in concrete bunkers and/or by encapsulation. The addition of MagnaDense to the concrete used, 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 with MagnaDense

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.

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