Chemical reactions are undesirable and are not a feature of the intended reactor behaviour. The water quality in the primary circuit in a PWR or BWR must be well controlled both to avoid chemical reactions with the reactor materials (steel and zircaloy) and to avoid picking up radioactivity as far as possible. What is wanted is a reactor assembly that undergoes as little chemical reaction as possible, in order to prolong the reactor life up to 60 years.
In gas cooled (that is carbon dioxide cooled) reactors as built in the UK, corrosion of steel components was a problem in the magnox type and resulted in maximum gas temperature being limited with loss of output. In the AGR all the hot end of the reactor had to be made of stainless steel to avoid corrosion.

What are fuel cells in a neclear reactor?
Fuel cells in a nuclear reactor are the structural components where nuclear fission reactions occur, generating heat. This heat is used to produce steam, which drives turbines to generate electricity. The fuel cells contain the nuclear fuel (such as uranium) and control rods to regulate the nuclear reactions.
What part of a nuclear reactor would most likely contain plutonium?
This part is the core of the nuclear reactor containing the nuclear fuel.
What is the function of a nuclear fuel in nuclear reactor?
The function of nuclear fuel in a nuclear reactor is to undergo controlled fission reactions, releasing energy in the form of heat. This heat is used to generate steam, which drives turbines to produce electricity. The fuel typically used is uranium or plutonium.
How to control nuclear reactions?
Nuclear reactions can be controlled through measures such as inserting control rods into the reactor core to absorb neutrons, adjusting the concentration of the reactor fuel, and controlling the flow of coolant to manage the rate of reaction. These methods help regulate the nuclear chain reaction and maintain a stable operating condition within the reactor. Additionally, operators continuously monitor and adjust these parameters to ensure the safe and efficient operation of the nuclear reactor.
Is nuclear energy and nuclear fuel the same thing?
No, they are not the same. Nuclear energy refers to the energy produced through nuclear reactions, while nuclear fuel is the material (such as uranium or plutonium) that undergoes fission reactions to release energy in a nuclear reactor. Nuclear fuel is used to generate nuclear energy.
What is the difference between the nuclear reactions in a nuclear reactor and those in an atomic bomb?
Nuclear reactions in a nuclear reactor are controlled reactions. The reactions in the atomic bomb are not controlled reactions
Why does nuclear chemistry happen?
The object of nuclear chemistry is the study of radioactive materials, nuclear wastes, chemical reactions in a nuclear reactor etc.
What is the function of reflector and reactor core?
The reflector in a nuclear reactor helps to reflect neutrons back into the reactor core, increasing the chances of nuclear reactions occurring. The reactor core is where the nuclear reactions take place, generating heat that is used to produce electricity.
What is the place where controlled nuclear fission reactions take place?
The place where controlled nuclear fission reactions take place is called a nuclear reactor. In a nuclear reactor, uranium atoms are split in a controlled manner to produce heat energy, which is used to generate electricity.
Where is the nuclear energy produced in a nuclear reactor?
Nuclear energy is produced in the core of a nuclear reactor, where controlled nuclear fission reactions occur. These reactions release heat energy, which is then used to generate electricity through steam turbines.
Can a nuclear reactor detonate the way a nuclear bomb can?
No, a nuclear reactor cannot detonate like a nuclear bomb. Nuclear reactors use controlled fission reactions to generate heat for electricity, while nuclear bombs use uncontrolled chain reactions to create an explosion. The design and purpose of a reactor prevent it from causing a nuclear explosion.
What is the difference between the nuclear reactions taking place in the sun and the nuclear reactions taking place in a nuclear reactor?
The sun's nuclear reactions are fusion reactions at extremely high temperatures and pressures, while the nuclear reactor's nuclear reactions are fission reactions at typical temperatures and pressures for earth.
What is the purpose of the reactor vessel?
The reactor vessel is the main container that houses the nuclear fuel, control rods, and coolant in a nuclear reactor. Its purpose is to contain and shield the nuclear reactions happening inside, and to provide structural support and safety for the reactor core.
What are fuel cells in a neclear reactor?
Fuel cells in a nuclear reactor are the structural components where nuclear fission reactions occur, generating heat. This heat is used to produce steam, which drives turbines to generate electricity. The fuel cells contain the nuclear fuel (such as uranium) and control rods to regulate the nuclear reactions.
The rate at which reactions occur in a nuclear reactor is regulated by?
The rate of reactions in a nuclear reactor is regulated by control rods made of materials like boron or cadmium, which absorb neutrons and help control the nuclear fission process. By adjusting the position of these control rods, operators can control the rate of reactions and the amount of heat produced in the reactor.
How are nuclear reactions that take place in the sun different from the nuclear reactions that take place in a nuclear reactor?
sun, fusion of hydrogen nuclei making helium nuclei (not radioactive)nuclear reactor, fission of uranium nuclei making a wide variety of different fission product isotopes having mass numbers from 72 to 161 (all very radioactive)
What is the difference between the nuclear reactions taking place in the sun and in a nuclear reactor?
The nuclear reactions in the Sun primarily involve fusion of hydrogen nuclei to form helium, releasing energy in the process. In a nuclear reactor, the reactions typically involve fission of heavy nuclei like uranium or plutonium, releasing energy through splitting these nuclei. The conditions and mechanisms governing the reactions in the Sun and in a nuclear reactor are different due to the vastly varying scales and environments of the two systems.
