10B in the form of Boric Acid for the Nuclear Industry

  • Enriched Boric Acid for use as a chemical shim for excess neutron absorption in the primary circuit of PWRs using high burnup or MOX fuel cores.
  • In these PWRs neutron absorption of natural Boric Acid is insufficient. Solubility of Boric Acid limits the boron concentration in primary circuit water to be used as neutron poison.
  • Today more and more enriched Boric Acid (95 % enriched in 10B) is used by NPPs.
