A facility for carrying out R&D for pyroprocess technology development has been set up. It consists of Pre-engineered building housing the main systems/equipment with surrounding platforms on two sides for utilities. Inside the building a large argon atmosphere containment box (CB) of 18.5m length, 3.5m width, 6.0m height, is supported on a steel structure at first floor level.
Argon systems, for maintaining pressure, temperature and oxygen & moisture concentration inside the CB, are provided at the ground floor level.
High Temperature Electrorefiner (HTER), for electrorefining, and Automated Vacuum Distillation & Melting System (AVDMS), for cathode product consolidation, are the main process equipments housed inside CB.
A glovebox is attached to CB for transfer of process materials. The building also houses a system for preparation of Eutetic mixture of LiCl-KCl with less than 50 ppm of moisture.
