Ontario Hydro operates a 10000 MW capacity nuclear power system utilizing the CANDU pressurized heavy water reactor design. The use of D2O as moderator and coolant results in the production of about 2400 Ci * of tritium per MWe-yr. As a result, there is significant Canadian experience in the treatment, handling, transport and storage of tritiated wastes. Ontario Hydro operates its own reactor waste storage site which includes systems for volume reduction, immobilization and packaging of wastes. In addition, a facility to remove tritium from heavy water is presently being commissioned at the Darlington nuclear site. This facility will generate tritiated liquid and solid waste that will have to be properly conditioned prior to storage or disposal. The nature of these various wastes and the processes/packaging required to meet storage/disposal criteria are judged to have relevance to investigations in fusion facility waste arisings. Experience to date, operational procedures being developed and ongoing R&D in this area are described.
