Lithium Aluminate Material Development

Lithium Aluminate Pellets

Lithium Aluminate Pellets Used in Commercial Nuclear Reactors for the Production of Tritium

Lithium aluminate is the preferred form for supplying lithium-6 targets for tritium production in commercial nuclear reactors. RMTD staff have worked in the area of lithium aluminate material development for more than 14 years and have worked to overcome the many potential barriers that stood in the way of successful implementation. RMTD staff memebers

  • worked with commercial vendors and universities to develop a powder synthesis method that produced flowable powder and enabled the automated processing necessary to produce production quantities of lithium aluminate pellets
  • worked with manufacturers to develop the commercial powder and pellet manufacturing capabilities necessary to produce over 1,000,000 one-inch pellets
  • worked with the National Institute of Standards and Technology (NIST) and Argonne National Laboratory (ANL) to develop production viable analytical chemistry methods to characterize the Li-6 loading in the final pellets. Successfully transferred these methods and qualified two separate laboratories for production measurements.
  • helped establish the Materials Control and Accountability (MC&A) protocols necessary to manage the accountable quantities of Li-6 enriched lithium materials used in the manufacture of these pellets
  • continue to develop unique lithium aluminate ceramics and lithium aluminate/zirconium cermet test specimens to use in Advanced Test Reactor (ATR) experiments designed to further the understanding of how pellets produce and release tritium during irradiation.
