What are the moderator used in a nuclear reactor with natural uranium?
Graphite rods are used as moderators in a nuclear reactor with natural uranium. Graphite slows down the fast neutrons released during fission reactions, allowing them to cause further reactions and sustain the chain reaction. This is necessary because natural uranium is not as efficient at sustaining a chain reaction without a moderator.
The element most commonly used as a fuel in nuclear fission reaction is?
The element most commonly used as a fuel in nuclear fission reactions is uranium-235. It is a naturally occurring isotope of uranium that can sustain a chain reaction under controlled conditions in nuclear reactors.
What weapons are made uranium?
Uranium is most commonly used in the production of nuclear weapons, such as atomic bombs or nuclear warheads for missiles. It is used as fuel in nuclear reactors to create controlled chain reactions for electricity generation and in some military applications.
What contains a heavy atom often used in nuclear fission reactions to produce thermal energy?
Uranium-235 is a heavy atom commonly used in nuclear fission reactions to produce thermal energy. When a uranium-235 atom absorbs a neutron, it becomes unstable and splits into two smaller atoms along with releasing energy and additional neutrons, which can trigger a chain reaction.
Is used in nuclear fission is radioactive poisonous and is explosive?
Uranium-235 is used in nuclear fission reactions to produce energy. It is radioactive, which means it emits radiation and can be harmful to living organisms if not handled properly. While uranium itself is not explosive, under specific conditions, such as critical mass, it can lead to a chain reaction resulting in an explosion.

Why does uranium metal not explode in a nuclear reaction?
Uranium metal (enriched in uranium-235 up to 99 %) is a nuclear explosive, if the critical mass is reached. Also criticality accidents are possible in uranium plants or uranium storage areas.
Do chain reaction takes place in nuclear reactor?
Yes, chain reactions take place in nuclear reactors. In a nuclear reactor, the chain reaction involves the splitting of uranium atoms (fission) which releases energy and more neutrons, leading to further fission reactions. Control rods are used to regulate and maintain the chain reaction at a steady rate.
What weapons are made uranium?
Uranium is most commonly used in the production of nuclear weapons, such as atomic bombs or nuclear warheads for missiles. It is used as fuel in nuclear reactors to create controlled chain reactions for electricity generation and in some military applications.
What type of uranium is used in nuclear power plants?
The type of uranium used in nuclear power plants is uranium-235. It is the isotope of uranium that is fissile, meaning it can sustain a nuclear chain reaction.
What fuel is used in nuclear power plants?
A nuclear reactor is a device to initiate, control, and sustain a nuclear chain reaction. Nuclear power is energy produced from controlled nuclear reactions. When it comes to just standard fuel across the table it would have to be: Plutonium, Uranium, and Thorium.
What starts the nuclear chain reaction in a nuclear reactor?
The nuclear chain reaction in a nuclear reactor is started by the splitting of uranium atoms, a process known as nuclear fission.
What contains a heavy atom often used in nuclear fission reactions to produce thermal energy?
Uranium-235 is a heavy atom commonly used in nuclear fission reactions to produce thermal energy. When a uranium-235 atom absorbs a neutron, it becomes unstable and splits into two smaller atoms along with releasing energy and additional neutrons, which can trigger a chain reaction.
If carbon were used as nuclear fuel it would be best?
Carbon is not commonly used as nuclear fuel because it does not readily undergo nuclear fission reactions. Elements such as uranium and plutonium are more suitable for use as nuclear fuels due to their ability to sustain nuclear chain reactions.
Why does a chain reaction not occur in uranium mines?
Mainly because only about 0.7% of uranium is the isotope uranium-235, which is easily fissionable. It is believed that in Earth's remote past, there were such chain reactions - natural reactors - at a time when the percentage of U-235 was higher.
Where does the reaction occur in nuclear fission?
Nuclear fission reactions typically occur in the core of a nuclear reactor. This is where the fissionable material, such as uranium-235, is bombarded with neutrons, causing the nuclei to split and release more neutrons and energy in a chain reaction.
