Conditioning and Packaging of Tritiated Waste from Ontario Hydro's Tritium Removal Facility

Tritiated waste from the Darlington Tritium Removal Facility requires conditioning and packaging to make it suitable for long term storage or disposal. Research to ensure daily tritium releases from tritiated waste packages do not exceed 10⁻³% of the inventory has shown that a 1cm thick high density polyethylene container is able to contain tritium from all types of waste expected to be generated from the facility including tritiated oils. Immobilization of tritiated liquids does not provide significant tritium retardation and is required only to prevent dispersion of the contents. Structural integrity of the tritiated waste package during transportation and disposal is provided by a high density polyethylene or metallic overpack.
