How waste is managed
See how the health, safety and security of all Canadians is incorporated into how Ontario Power Generation transports, processes and stores waste products from our facilities.
Licensed and regulated
The Canadian Nuclear Safety Commission (CNSC) regulates all OPG nuclear sites, including the use of nuclear energy and materials to safeguard health and the environment, to insure safety and security, and to respect Canada’s international commitments on the peaceful use of nuclear energy.
OPG accepts, transports, stores and processes all waste thoughtfully and carefully, with an ongoing dedication to the security of Ontarians as our first concern.
How is waste managed?
Western Waste Management Facility (WWMF)
Designed to store 2,000 Dry Storage Containers, the WWMF went into operation in 2002.
The facility stores low- and intermediate-level nuclear waste from the operation of OPG's 18 owned nuclear reactors, including eight leased to Bruce Power. In addition, the facility provides dry fuel storage for the Bruce reactors.
Low- and intermediate-level waste generated is safely transported and stored on an interim basis at the WWMF.
- Low-level waste is sorted and, when possible, compacted or incinerated to reduce the volume. After processing, low-level waste is stored in above-ground concrete warehouses.
- Intermediate-level waste from station operations is stored in steel-lined concrete containers and set in the ground. While low- and intermediate-level waste is safely stored on an interim basis, it will eventually be transferred to the proposed Deep Geologic Repository site for permanent disposal — the lasting solution.
