The National Radioactive Waste Disposal Institute (NRWDI) is moving ahead with preliminary designs for a so-called Centralised Interim Storage Facility (CISF) at the Vaalputs site in the Northern Cape to store spent fuel arising from Eskom’s Koeberg nuclear power station. While the South African Nuclear Energy Corporation, or Necsa, currently holds the licence to operate the Vaalputs radioactive waste disposal facility, NRWDI is in the process of seeking to have the licenced transferred.
