A nuclear change -- involves changes in nuclear structure, such as fission (splitting) of a nucleus or an atom, or fusion (combining) of neutrons and protons to form heavier atoms. This involves about 1,000,000 times as much energy as a chemical change. And also a nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. The most common use of nuclear reactors is for the generation of electrical power (see Nuclear power) and for the power in some ships (see nuclear marine propulsion). This is usually accomplished by methods that involve using heat from the nuclear reaction to power steam turbines. There are also other less common uses as discussed below. All nuclear reactors are devices designed to maintain a chain reactionproducing a steady flow of neutrons generated by the fission of heavy nuclei. They are, however, differentiated either by their purpose or by their design features. In terms of purpose, they are either research reactors or power reactors.
What else can I help you with?
Fission and fusion is an example of what kind of energy?
One type of atom (element or isotope) is converted to another. This is called nuclear reaction.
What happens to matter when it is converted in a nuclear reaction?
In a nuclear reaction, matter is converted into energy.
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 is the part of a nuclear reactor called where the nuclear reaction takes place?
The part of a nuclear reactor where the nuclear reaction takes place is called the reactor core. It typically contains the fuel rods, control rods, and coolant necessary for sustaining and controlling the nuclear reaction.
What type of reaction happens in a nuclear power plant?
A nuclear fission reaction occurs in a nuclear power plant. This is the process where the nucleus of an atom is split, releasing large amounts of energy in the form of heat, which is used to generate electricity.
What is a example of nuclear reaction?
An example of a nuclear reaction is nuclear fusion, where two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process. This reaction is the process that powers the sun and other stars.
What is an example of uncontrolled nuclear fission reaction?
Atomic fission bomb.
In a nuclear reaction engery is released by the combination of two elements into a new element this process is an example of?
nuclear fusion
Fission and fusion is an example of what kind of energy?
One type of atom (element or isotope) is converted to another. This is called nuclear reaction.
What is the minimum amount of material needed to sustain a nuclear reaction?
The minimum amount of material needed to sustain a nuclear reaction depends on the type of reaction. For example, in a nuclear fission reaction, a critical mass of fissile material is needed to sustain a chain reaction. In a fusion reaction, high temperatures and pressures are needed to overcome the electrostatic repulsion between nuclei.
State wether a nuclear fusion is a chemical reaction or a nuclear reaction?
Nuclear
How do you say nuclear reaction in German?
nuclear reaction= Kernreaktion
Is an example of nuclear fission?
An example of nuclear fission might be a nuclear weapon. In this device, sub-critical masses of fissionable material are driven together by conventional explosives. This "assembles" a critical mass, and a chain reaction will follow. That is a nuclear fission chain reaction. In another example, a nuclear reactor has its control rods pulled and achieves criticality. It is brought to operating temperature and generates heat to make steam and drive turbines. The reactor operates on the principle of nuclear fission.
Why is plutonium found in nuclear reactors?
Plutonium is a by product of nuclear reactions of uranium in a nuclear reactor. An example of reaction is: 23892U + n-------23992U-------23993Np + e--------23994Pu + e
What is the nuclear reaction for beryllium?
One example of a nuclear reaction involving beryllium is the reaction of beryllium-9 with an alpha particle (helium-4 nucleus) to produce carbon-12 and a neutron. This reaction is important in stellar nucleosynthesis and occurs in high-energy environments such as inside stars.
Is fusion a type of chemical reaction?
False
What describes a nuclear reaction?
nuclear
