Hot-cell Renovation in the Spent Fuel Conditioning Process Facility at KAERI
The Advanced spent fuel Conditioning Process Facility (ACPF) of the Irradiated Materials Examination Facility (IMEF) at the Korea Atomic Energy Research Institute (KAERI) has been renovated to implement a lab-scale electrolytic reduction process for pyroprocessing. The interior and exterior structures of the ACPF hot-cell have been modified under the current renovation project for the experimentation of the electrolytic reduction process using spent nuclear fuel. 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. Based on the considered refurbishment workflow, previous equipment in the M8 cell, including vessels and pipes, were removed and disposed of successfully after a zoning smear survey and decontamination, and new equipment with advanced functions and specifications were installed in the hot-cell. Finally, the operating area and isolation room were also refurbished to meet the requirements of the improved hot-cell facility.
