2. EWI – Quick Snapshot • Founded to develop and deploy new materials, joining, and inspection technology • Located in Columbus, Ohio in a 132,000 square foot facility • >$20 million in capital equipment • Mix of industry and government clients • Not-for-profit, 501(c)(3) organization with revenue ~$25 million and over 130 employees • 247 Members spread across more than 3000 global locations Fundamental Research Technology Development TechnologyApplication Member Companies Universities & National Labs

3. EWI – Centers and Consortia Maximizing technology implementation through industrial collaboration and public/private partnerships

4. Laser Decontamination

5. EWI Laser Decontamination Technology • Smallest, lightest, highest powered scanner • Highest efficiency and paint stripping rates • Best recorded effluent removal of any available system • Integrated process control • Able to remove all colors (tested to date) • System works with multiple laser platforms • CO2 Laser, Nd YAG, Fiber • Travel speed • 40 to 80 inches per minute • Adjustable processing width

6. Portsmouth D&D Challenges • Cleanup of DOE sites are technically challenging because of • Personnel hazards • Large size of facilities • Complex, crowded and often retrofitted arrangement of equipment and structures • Poorly understood and difficult-to-characterize contaminants • Lack of decisions on facility end states • Facility D&D comments from multiple DOE reports • D&D work relies on manual labor for building characterization • Removing contamination from building walls, other surfaces and equipment can be slow and ineffective • Personal protective equipment tends to be heavy, hot and limits movement of workers

7. Increased Recycling Opportunity • Two categories for Portsmouth/Piketon metals • Must bury • Recycle A. For use in nuclear industry B. For use in any industry • EWI technology could reduce item 1 while significantly increasing the quantity and quality of materials for items 2A and 2B. • Mix of Technology • Laser Decontamination Surface Contaminants (>100M lbs) • Chemical Vapor Refining Through Thickness Ni (>10M lbs) • Steel Mill All scrap metal forms

8. Technical Applicability to Portsmouth D&D Effort • EWI’s Laser Decontamination system has the ability to; • Remove all contaminates encapsulated in the painted surfaces of structural concrete, steel and composites on the site • Reducing total tonnage slated for burial • Improved environmental protection by decontaminating while still under roof • All contaminants contained in combustion product • Smaller quantity (unfortunately with higher localized contamination) • No secondary waste streams generated -- no blast media or chemicals • Unknown variable • Radiologically contaminated materials

9. Sustainable Business Opportunity • Personnel and environmental safety are top priority during D&D activities • ~3000 DOE sites in the U.S. planned for closure and D&D in the future • Unknown quantity of similar sites internationally • DOE sites alone could create decades of sustainable jobs and business growth

10. Potential Partnerships • Wastren/Hadsell Development • Laser Decontamination • Potential Funding Sources • Recycling Revenue • State of Ohio • Federal government • Private Investment • Labor Unions • Steel Mills and Fabricators • Other Corporate Partners
