Energy Alberta is considering two advanced, Canadian-owned nuclear reactor technologies: Atkins Réalis’ CANDU® and Westinghouse’s AP1000®.
While there are some differences in the design, the outcome is the same: deliver large-scale, reliable, low-emissions electricity that Alberta can depend on for decades.
The CANDU® and AP1000® build on decades of operating experience, incorporating proven features from existing plants alongside modern design updates that enhance safety, performance and efficiency, including modular construction, digital controls and advanced monitoring systems to support reliable, long-term operation.
Both options are based on proven technologies designed to meet rigorous Canadian and international safety standards. The final technology selection will be informed by Project‑specific requirements, lifecycle cost assessments, regulatory alignment and long‑term economic value.

The federal impact assessment process for the Project will use a Plant Parameter Envelope (PPE) approach. In simple terms, a PPE is a bounding "envelope" of parameters that define the site and plant characteristics, allowing assessments to begin before a reactor technology is selected.
This approach allows potential environmental, safety and socio-economic effects to be assessed now, rather than waiting for a final reactor selection. It ensures that potential impacts do not exceed what is defined within the PPE. This method has been used in previous nuclear project reviews in Canada and the United States.
Nuclear energy is the energy released from the nucleus (core) of atoms, primarily through a process known as nuclear fission. Fission is a reaction that occurs when atoms of uranium are split into two or more smaller nuclei. The process releases large amounts of energy in the form of heat, which is converted into electricity by creating steam in a nuclear power plant.

The process begins in the reactor, where uranium atoms are split by neutrons. This releases a significant amount of heat.
The heat produced by fission is transferred to a separate system where it is used to turn water into steam.
The steam spins a turbine connected to a generator, which produces electricity.
After passing through the turbine, the steam is cooled and returned to water, which is then heated again to repeat the cycle. The cooling water used in this process is kept separate from the steam cycle and does not come into contact with the reactor core.
All of Canada’s used nuclear fuel is safely managed at licensed storage facilities.
Energy Alberta is deeply committed to protecting the water, air, land and people around our Project. Safety is not just a priority - it is at the core of our values. The use of nuclear power in clean energy production is tightly regulated and monitored to ensure the highest standards of public and environmental safety.

September 30 is a day to remember, reflect and listen. On National Day for Truth and Reconciliation, we recognize the lasting impacts of the residential school system and encourage our team and community to make space for Indigenous voices, stories and experiences. It is also an opportunity to consider what reconciliation means in the places where we live and work - not only today, but throughout the year.
On September 27, people around the world will mark World Rivers Day - an opportunity to recognize the extraordinary value of rivers and the importance of protecting them for the future. For Energy Alberta, it’s also an opportunity to celebrate a river that is central to the region where we are planning the Peace River Nuclear Power Project.
When people think about nuclear energy, one of the first questions they often ask is: How much does it cost? It's an important question - but it's also one that deserves a broader conversation. Like any major infrastructure project, the value of nuclear energy isn't measured by upfront capital costs alone. It's measured over decades of reliable electricity generation, long-term economic benefits and the lasting impact it can have on communities, workers and businesses.
