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
