Why process abroad?
• No current facilities in UK that can process metal via melting
• Currently around five melting facilities abroad
• To conduct melting trials a need to engage foreign companies
• Proven technology
• New Defra LLW policy with new policy on import and export
• NDA strategic BPEO to use overseas treatment facilities

Why melting?
• Acts as an effective decontamination process for most metals and associated radionuclide contamination
• Achieves complete volume reduction of the material
• Homogenises the metal for robust characterisation
• Provides an opportunity for re-use and recycling of valuable material

Metal melting by recycling
• The Studsvik Treatment Concept is based on recycling the treated material and minimising the volume of contaminated material that is returned to the customer
• Typically >95% of the incoming material to Studsvik is recycled, for lead up to 97% is recycled
Recycling 1 tonne of steel saves:1.5t iron ore0.5t coal1.3t solid waste
Water use 60% lessEmissions 86% lessEnergy 75% less

Lead Melting Trial•Release of ingots for re-melting is made in accordance with the European Commission’s Recommendations in RP89
•Network of metal producers in Sweden familiar with the ingots as a feedstock
•Secondary wastes (slag, blasting residues, filter dust) are conditioned, packaged and returned to the country of origin for disposal
