Abstract

South Africa initiated a program to significantly expand its total nuclear energy capacity by acquiring additional Pressurized Water Reactors (PWRs) and is currently researching Pebble Bed Modular Reactors (PBMRs) as next generation nuclear energy sources. The result of such an expansion in the current nuclear program will be a need for the disposal of additional nuclear waste. However, as an alternative strategy for spent PBMR fuel, the separation of the spent fuel into TRISO particles for disposal and graphite for re-use in the nuclear industry could also be considered.
