Heavy water, which contains deuterium instead of regular hydrogen, is used as a moderator in nuclear reactors because it slows down neutrons more efficiently than regular water. This helps maintain a sustained nuclear reaction by increasing the likelihood of neutron interactions with fuel nuclei. Additionally, heavy water is less prone to absorbing neutrons, which can help sustain the nuclear chain reaction.

What is a heavy element used in nuclear bombs and nuclear energy?
When it comes to heavy elements that are used in weapons and in reactors, uranium and plutonium are both candidates. The first atomic bombs were made of uranium, and they are now pretty much made of plutonium. Some special nuclear reactors are powered by plutonium fuel, but most reactors for power generation use (enriched) uranium for fuel. Links are provided to relevant articles posted by our friends at Wikipedia, where knowledge is free.
Does plutonium use for fuel nuclear?
Yes, plutonium is used as a fuel in nuclear reactors, specifically in certain types of reactors like fast breeder reactors and some types of advanced reactors. Plutonium-239, which is produced from uranium-238 in nuclear reactors, is a key fuel component due to its ability to sustain fission reactions.
Why can't ordinary uranium be used in reactors coooled by ordinary water?
Because the neutron economics are against it, a critical reactor and a chain reaction would not be possible. Ordinary water absorbs too many neutrons. For natural uranium you must use graphite or heavy water for the moderator.
Why use plutonium in nuclear reactors?
Plutonium is used in nuclear reactors as a fuel because it can undergo fission, producing energy in the process. It is created as a byproduct in uranium-fueled reactors and can be recycled for use as fuel in mixed-oxide (MOX) fuel. Plutonium helps extend the fuel cycle and reduce waste by utilizing more of the energy content in nuclear fuel.
Is plutonium used in power plants?
Yes, plutonium is used as a fuel in certain types of nuclear reactors, such as breeder reactors. These reactors are designed to produce more plutonium than they consume, as a way to generate energy and also produce more fuel for future use.
What process do nuclear reactors use?
Nuclear reactors use nuclear fission.
Why is only heavy water used as coolant for nuclear energy and can you use any other coolant used replacing D2O?
Many pressurized water reactors use "regular" water (light water) as a primay coolant. That means that "only heavy water" is not a rule as regards reactor design. Reactor design specifies the coolant to be used.
Most of the world's nuclear reactors are of the type?
Most are lightwater moderated and cooled, these are the PWR and BWR. There also a substantial number of heavy water reactors, based on CANDU, and gas cooled reactors mainly now in the UK.
What is a nuclear reaction coolant?
Presumably you mean nuclear reactor coolant? This is the fluid that transfers the reactor thermal output to the steam raising units in a PWR, or to the turbine in a BWR, in which cases it is natural water. Gas cooled reactors can use carbon dioxide or helium, and CANDU reactors use heavy water.
What nuclear energy is the United States using?
In 2007, US nuclear power plants generated 806.5 billion KWh. This was 19.4 percent of total US electricity. 69 PWR and 35 BWR reactors contributed to this total. Source: Nuclear Energy Institute, www.nei.org
What do you use heavy water for?
Moderator in some types (e.g. Candu) of nuclear reactor to slow high energy fission neutrons to thermal energies.In small quantities it can be used for MRI contrast.It can be used to slow chemical reactions in water solution.etc.
Most of the nuclear power plants currently operating in the US are classified as.....?
Most nuclear power plants currently operating in the US are classified as pressurized water reactors (PWRs). These reactors use water as both a coolant and moderator to generate electricity through nuclear fission. PWRs are the most common type of nuclear reactor in use worldwide.
Does nuclear energy contain water?
no. most reactors use water as coolant and/or moderator, but nuclear energy is energy and contains no matter.
Nuclear power plants require large volumes of what to cool reactors and convert heat to electricity?
Nuclear power plants require large volumes of water to cool reactors and convert heat to electricity. Reactors use normal water, heavy water, and even newer reactors use other forms of coolant.
How do nuclear reactors use periscopes?
Nuclear reactors do not typically use periscopes. Periscopes are usually used in submarines to see above water while remaining submerged. Nuclear reactors utilize control rooms with monitoring equipment and cameras to observe and control the reactor's operations.
Does nuclear reactors and breeder reactors have any similarities?
They're mostly the same, except that nuclear reactors aimed at breeding more fissile material use expensive primary coolant instead of cheap water.
What nuclear reaction is currently used to produce nuclear energy in nuclear reactors?
We use nuclear fission in nuclear reactors to tap nuclear energy.
