The major aim of this study was to develop a process to treat non-recoverable waste from the Tihange power plant, to achieve a reduction in both the reject activity and the volume of end product, which is sealed in casks. A flocculation process has been worked out for each type of waste, i.e. residual, service, laundry, decontamination, pool and reclamation wastes. An investigation has also been made into the effects of substances that might disturb this flocculation and ways of eliminating them. In order to reduce the volume of waste, a centrifugation plant with a rated flow of 800 l/h has been developed and operated jointly with an industrial batch flocculation (35 m3) located in Tihange. Finally, comparative tests have been performed in the Tihange power plant, using both the UKAEA and LABORELEC processes on the same waste product.
