Previously, the CNSC published annually, a regulatory oversight report (ROR) for Canadian nuclear power plants. The most common power plants in the world use pressurized water reactors, which use two loops of circling water to produce steam. Under a normal operating licence, the operator can place the nuclear facility in safe storage, if it so wishes, as an initial step to decommissioning.

Power stations with past net capacity over 1,000 MW and current net capacity under 1,000 MW are listed in third table. [4] Hot water cools in contact with the air and a small portion, around 2%, evaporates and raises up through the top.

Stations with both operational and permanently shut-down reactors and current capacity under 1,000 MW (but in the past over 1,000 MW) are also listed.

They get their thermal power from splitting the nuclei of atoms in their reactor core, with uranium being the dominant choice of fuel in the world today.

Lamarsh and A.J. The licensing process offers significant opportunities for public participation, including Commission hearings and community meetings that are open to the public and webcast live.

The results are published in the Regulatory Oversight Report for Canadian Nuclear Power Generating Sites: 2017.

The decision to stop operating and to decommission the reactor is taken solely by the licensee. In the future, all radioactive waste will be removed from those locations, and decommissioning will eliminate any unreasonable risks to health, safety, security and the environment.

Moreover, these plants do not release any carbon dioxide—the primary greenhouse gas that contributes to climate change. Decommissioning activities are the actions a licensee undertakes at the end of the useful life of the reactor. Aside from the source of heat, nuclear power plants are very similar to coal-fired power plants. The CNSC regulates the entire lifecycle of nuclear power plants. Capacity of permanently shut-down reactors is not included, but capacity of long-term shut-down reactors (today mainly in Japan) is included. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy. This table lists stations under construction or operational stations with under-construction reactors and current net capacity under 1,000 MW. Baratta, "Non-Nuclear Components of Nuclear Power Plants" in. Many nuclear power plants simply put the waste heat into a river, lake or ocean instead of having cooling towers.

These get up to extremely high speeds, causing the steam to lose energy, therefore, condensing back to a cooler liquid water. In addition to having a team of onsite inspectors, CNSC staff with specific technical expertise regularly visit plants to verify that operators are meeting the regulatory requirements and licence conditions. The CNSC assesses licence applications to ensure that safety measures are technically and scientifically sound, that all requirements are met, and that the appropriate safety systems are in place to protect people and the environment.

Perhaps the most iconic symbol of a nuclear power plant is the cooling towers, seen in Figure 4. Nuclear power plants heat water to produce steam. At that point, those facilities will be issued abandonment licences to release them from CNSC regulatory control. The steam is used to spin large turbines that generate electricity. Three prototype nuclear reactors constructed and owned by Atomic Energy of Canada Limited were shut down and prepared for decommissioning in the 1980s in Rolphton and Kincardine, Ontario and in Bécancour (Gentilly-1). [6], Once steam has been produced, it travels at high pressures and speeds through one or more turbines.

Some of these may have reactors under construction, but only current net capacity is listed.

The reactor is what makes it differ from other external heat engines. Nuclear energy produces about 15 percent of Canada's electricity.

Michael Kappel on Flickr [Online], Available: J.R. Lamarsh and A.J. The CNSC has a team of technical experts and onsite inspectors to ensure that rigorous oversight of plant operation is maintained, in order to protect the public and the environment. Today, five plants in three provinces house 22 nuclear power reactors. World Nuclear Association. The reactor is the heat source for the power plant, just like the boiler is for a coal plant.

The Canadian Nuclear Safety Commission (CNSC) regulates 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 are ended. [6] The first loop carries extremely hot liquid water to a heat exchanger, where water at a lower pressure is circulated.

Uranium is the dominant nuclear fuel used in nuclear reactors, and its fission reactions are what produce the heat within a reactor. [4] The power plant encompasses not just the reactor, but also cooling towers, turbines, generators, and various safety systems.

Every three years, the CNSC publishes a comprehensive report as part of the Convention on Nuclear Safety, following up on its commitment to maintain a high level of safety at all nuclear power plants. Today, five plants in three provinces house 22 nuclear power reactors. Thorium also has potential use in nuclear power production, however it is not currently in use.

The reactor is a key component of a power plant, as it contains the fuel and its nuclear chain reaction, along with all of the nuclear waste products. The rotation of the turbines is used to spin an electric generator, which produces electricity that is sent out the the electrical grid.[8]. New reactor facility projects are being considered in some parts of Canada. Boiling water reactors, the second most common reactor in power generation, heat the water in the core directly to steam, as seen in Figure 2. This similarity exists because the process of turning heat into electricity is almost identical between nuclear power plants and coal-fired power plants.

The CNSC's role is to ensure that decommissioning activities are carried out in accordance with CNSC regulatory requirements to ensure protection of the workers, the public and the environment, and to implement Canada's international commitments on the peaceful use of nuclear energy.
