Reactors
Two basic types of nuclear reactors are in operation in Canada: power reactors and research reactors.
We regulate and license both types of reactors and the entire lifecycle of nuclear power plants in order to protect the environment and the health, safety and security of Canadians.
Services and information
Overview
Two basic types of nuclear reactors are in operation in Canada: power reactors and research reactors.
New reactor facility projects
We make independent, fair and transparent decisions on licensing new reactor facilities.
Nuclear power plants
We regulate all stages of the life of each nuclear power plant in Canada, from the environmental assessment required before plant construction, to the decommissioning of the facility once operations have ended.
Operating nuclear power plants
Nuclear power plants have been producing electricity commercially in Canada since the early 1960s.
Nuclear Power Plant Safety Systems
Each nuclear power plant in Canada has multiple robust safety systems designed to prevent accidents, and reduce its effects should one occur.
Refurbishment and life extension
The life of a nuclear power plant can be extended for several decades through refurbishment to modernize and enhance major equipment and systems in support of long-term operation.
Decommissioning activities
Decommissioning activities are the actions a licensee undertakes at the end of the useful life of the reactor. The decision to stop operating and to decommission the reactor is taken solely by the licensee.
Convention on Nuclear Safety
Countries that are signatory to the Convention on Nuclear Safety commit to maintaining a high level of safety in the operation of nuclear power plants.
Map of nuclear facilities
This map shows the locations and types of nuclear facilities.
Small modular reactors
Nuclear reactors of varying sizes and power outputs are used in Canada for a range of applications, such as research, materials testing, medical uses and electrical power generation.
Research reactors
Canada has a number of research reactors across the country.
Shut-down and decommissioned reactors
Canada has a variety of research and prototype power reactors that are no longer in use and have been shut down.
Defence in depth
Reactor facilities in Canada operate with 5 independent and redundant layers of defence that aim to prevent and mitigate accidents.
