The Low-Level Radioactive Waste Management Office (LLRWMO) manages Low-Level Radioactive Waste (LLRW) at a number of historic waste sites located throughout Canada, including locations in Ontario, Alberta and the Northwest Territories. Small volumes of LLRW are transported to the LLRWMO storage buildings at Canadian Nuclear Laboratories (CNL)’s Chalk River Laboratories (CRL) in Chalk River, Ontario. Larger volumes of LLRW are managed at or near their sites of origin.
At some of the historic waste sites, materials have been placed in interim storage pending the development and implementation of long-term management solutions. The LLRWMO conducts ongoing monitoring, inspection and maintenance at these interim storage sites. The historic waste at these sites includes uranium- and/or radium-contaminated soil, building materials and other contaminated items.
To enable it to carry out its responsibilities for interim management of LLRW and the associated technical activities, the LLRWMO currently holds four licences issued by the Canadian Nuclear Safety Mission (CNSC) for various facilities. Three relate to the operation of interim storage sites in Canada; the fourth is for the LLRWMO’s Environmental Laboratory in Port Hope, Ontario, where the LLRWMO maintains capabilities for sample preparation and analysis of low-level radioactive materials.
