International supply chain case study
International Supply Chain Case Study

  • Shipment and treatment of contaminated lead from Sellafield


International supply chain case study1
International Supply Chain Case Study

  • Supply Chain

  • Why process abroad?

  • Why metal melt?

  • Lead transport and melting case study


Supply chain
Supply Chain

  • NDA (UK) – Ultimate Customer

  • BNG Sellafield Ltd (UK) - Customer

  • Studsvik (Sweden with UK subsidiary)– Main contractor

  • MHF Logistical Solutions (USA) - Subcontractor

    • MHFLS chosen for their core competence in packaging and bulk transport of radioactive material


Studsvik
Studsvik

  • Studsvik is a leading nuclear services organisation with 1300 employees worldwide and sales of £100M+ per annum

  • Dedicated decontamination and melting facility in Nyköping, Sweden

  • To date processed in excess 15,000 tonnes of metal

  • Nuclear site license under Swedish regulators

Why process abroad
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
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

Recycling 1 tonne of steel saves:

Water use 60% less

Emissions 86% less

Energy 75% less

1.5t iron ore

0.5t coal

1.3t solid waste

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


Lead melting trial
Lead melting trial

  • Customer sourced candidate material for melting

  • Waste characterisation of the material

  • Package assessment and package approval

  • Transfrontier shipment documentation preparation

  • Letter of acceptance for the treatment of the lead


Lead melting trial1
Lead melting trial

  • Loading of the lead

    • Delivery of the containers to Sellafield

    • Loading of the lead in the packages

    • Securing of the packages

    • Preparation of transportation paperwork

  • Arrival of material at site

  • Unloading of material

  • Sorting of material

  • Size reduction

  • Melting

  • Analysis of melted material

  • Analysis of secondary waste

Ingots


Lead melting trial6
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


Lead melting trial7
Lead Melting Trial

  • Currently First and Second Shipment successfully delivered

  • First shipment of lead melted successfully with second shipment melting currently being processed at facility

  • BNG/Studsvik/MHFLS preparing for third shipment

  • Teamwork built on the core competences of the individual companies


Summary
Summary

  • Proven technology

  • Supply chain built on core competences of companies

  • Successful trial melt

  • Further scope for working together
