Heavy-water reactor meaning

Heavy-water reactor definitions

A heavy-water reactor is a type of nuclear reactor that uses heavy water as a neutron moderator. This type of reactor is known for its ability to use natural uranium as fuel, making it a cost-effective option compared to reactors that require enriched uranium.

How Does a Heavy-Water Reactor Work?

In a heavy-water reactor, heavy water, also known as deuterium oxide, is used to slow down neutrons produced during the fission process. This moderation allows the neutrons to efficiently collide with other uranium atoms, leading to a sustained chain reaction.

Advantages of Heavy-Water Reactors

One of the main advantages of heavy-water reactors is their ability to use natural uranium as fuel, which is more abundant and less expensive than enriched uranium. Additionally, heavy water is an excellent neutron moderator, allowing for a more efficient and reliable nuclear reaction.

Disadvantages of Heavy-Water Reactors

Despite their advantages, heavy-water reactors also have some disadvantages. Heavy water is more expensive to produce than regular water, making the initial setup costs of these reactors higher. Additionally, heavy-water reactors tend to be larger in size compared to other types of reactors.

In conclusion, heavy-water reactors play a significant role in the nuclear power industry due to their efficiency and ability to utilize natural uranium as fuel. While they may have some drawbacks, such as higher initial costs, their benefits make them a viable option for generating nuclear power.
