Lawrence Livermore National Laboratory (LLNL) and the Y-12 National Security Complex have teamed up to rapidly modernize legacy technology and production methods of crucial components for the U.S. nuclear deterrent.
A leading example of this collaboration is the recent successful installation and testing of the electron beam cold hearth melter (EBCHM) – a machine that can melt and cast various metals including uranium alloys. When compared with legacy production methods, EBCHM has the potential to improve material utilization, drastically reduce waste and shorten the cycle time for producing metal ingots.
EBCHM systems, commonly found across manufacturing industries for commercial purposes, is a favored fabrication technology for its efficiency in recycling and alloying high-melting-point metals for aerospace applications. LLNL’s early investments in fundamental materials research capitalized on the public EBCHM technology and discovered that the system could be used to reliably alloy and recycle uranium alloy materials.
To take the technology from concept to delivery, LLNL and Y-12 partnered to procure and install an EBCHM system in Oak Ridge, Tennessee. Utilizing manufacturing space in Oak Ridge and unique capabilities to handle hazardous materials has enabled the joint LLNL and Y-12 material teams to test and rapidly mature the EBCHM technology, with the goal of making it a standard production method for metal for stockpile components across the national security enterprise.
Y-12’s Depleted Uranium Technologies Program Manager Pamela Moor emphasized EBCHM’s capability to replace particularly difficult, multistep and expensive alloying processes seen in legacy production methods.
