The Advanced spent fuel Conditioning Process Facility (ACPF) of the Irradiated Materials Examination Facility (IMEF) at KAERI has been renovated to implement a lab-scale electrolytic reduction process for pyroprocessing.

The most important aspect of this renovation was the installation of the argon compartment within the hot cell. For the design and system implementation of the argon compartment system, a full-scale mock-up test and a three-dimensional simulation test were conducted in advance.

The remodeling and repairing of the process cell (M8a), the maintenance cell (M8b), the isolation room, and their utilities were also planned through this simulation to accommodate the designed argon compartment system.
