Gentilly-1 Waste Management Facility

Located within the Gentilly-2 generating station's boundary is the Gentilly-1 Waste Management Facility, which is operated by Canadian Nuclear Laboratories Ltd. (CNL). The Gentilly-1 Nuclear Power Station, which operated intermittently from 1972 to 1978, is also located on site. A decommissioning program was initiated in 1984 to bring the facility to a safe, sustainable shutdown state. The site is now partially decommissioned and in a storage-with-surveillance mode and is licensed as a waste facility.
