Two basic types of nuclear reactors are in operation in Canada: power reactors and research reactors.

Nuclear power reactors generate electricity.

Research reactors are used for scientific research and produce nuclear substances for medical and industrial use.

The Canadian Nuclear Safety Commission (CNSC) regulates and licenses both types of reactors in order to protect the health, safety and security of Canadians and the environment.

Inspectors and a team of highly qualified experts verify compliance and, whenever necessary, take enforcement measures to ensure facility operators correct deficiencies.

Many people live or work in communities close to nuclear reactors.

Consultation with the public, licensees and interested organizations, including the communities affected by these operations, is also an important part of the regulatory process.
