Top 10 Myths about Nuclear Energy

Myth #1: Nuclear energy is dangerous.

Fact: Nuclear energy is one of the safest forms of energy available. No member of the public has ever been injured or killed in the entire 60+ year history of nuclear power generation in Canada. In fact, recent studies have shown it is safer to work in a nuclear power plant than an office. (Source: NEI.org.)

Myth #2: A nuclear reactor can explode like a nuclear bomb.

Fact: It is physically impossible for a nuclear reactor to explode like a nuclear bomb. Reactor fuel does not have nearly enough uranium-235 to be explosive, and all nuclear reactors are constructed with multiple layers of safety controls and self-limiting features. It is also impossible for a person to intentionally or unintentionally modify a reactor, its controls or its fuel to cause an explosion.

Myth#3: Nuclear reactors emit dangerous amounts of radiation.

Fact: Nuclear reactors produce extremely small amounts of radiation. If you live within 75 km of a nuclear power plant, you receive an average radiation dose of about 0.0001 millisieverts per year. To put this in perspective, the average Canadian receives about 3 millisieverts per year from natural background sources of radiation.

Myth #4: Nuclear energy leads to the proliferation of nuclear weapons.

Fact: The Canadian nuclear industry is regulated by the Canadian Nuclear Safety Commission (CNSC), which ensures that the country does not manufacture or acquire nuclear weapons, and that nuclear exports do not contribute to the development of nuclear weapons. In the history of Canadian nuclear exports, there has only been one breach of contract, which resulted in severe sanctions.

Myth#5: Nuclear energy produces a huge amount of waste.

Fact: Nuclear energy produces a very small amount of waste compared to other energy sources. In fact, all of the used nuclear fuel generated in every Canadian nuclear plant in the last 60 years would fill 6 NHL hockey rinks to the boards. Additionally, unlike the waste produced by fossil fuels such as coal and natural gas, which is released into the air, nuclear waste is kept in secure storage.

Myth #6: There is no solution for the disposal of nuclear waste.

Fact: Nuclear waste is currently being safely stored at the nuclear site where it was generated. Two initiatives are currently underway in Canada to find Deep Geologic Repositories (DGRs) for nuclear waste – one for low and intermediate-level waste and one for used fuel – where it will be safe and secure for many generations to come. There are operational DGRs in several countries around the world.

Myth #7: Nuclear waste cannot be safely transported.

Fact: Nuclear waste is being safely shipped by truck, rail, and cargo ship. To date, thousands of shipments have been made without any leaks or cracks of the specially-designed containers. Some of the measures that contribute to the safe transportation of nuclear waste include expert engineering of vehicles and containers, rigorous screening and training of personnel, inventory tracking, and independent regulatory bodies.

Myth #8: Nuclear energy is expensive.

Fact: Nuclear power is one of the least expensive energy sources. In Ontario, it is second only to hydropower. Natural gas and wind are twice as expensive and solar is nearly ten times as expensive. Moreover, the cost of nuclear is very stable because uranium makes up only 30% of the cost of nuclear power, so an increase in the cost of uranium would have only a small effect on the total price.

Myth #9: Nuclear energy is being phased out.

Fact: Currently, there are 441 nuclear reactors in 29 countries producing 14% of the world’s electricity. Another 61 reactors are currently under construction in 15 countries. Furthermore, new reactor technologies, such as small modular reactors (SMRs), are under development, which will provide additional options for diverse countries around the world.

Myth #10: Nuclear energy is bad for the environment.

Fact: Nuclear reactors emit zero greenhouse gasses during operation. Over the entire lifecycle, which includes construction, mining, operation, and decommissioning, nuclear emissions are comparable to renewable energy sources such as wind and solar. Nuclear power also has minimal effects on aquatic habitats and uses less land than most other energy sources.
