What is necessary sustain a nuclear chain reaction?
In a chain reaction, neutrons released during the splitting of an initial nucleus trigger a series of nuclear fissions.
Hydrogen bombs and stars both produce energy with nuclear?
fusion reactions, where lighter elements combine to release tremendous amounts of energy. In stars, the fusion of hydrogen into helium powers their luminosity and heat. Hydrogen bombs use isotopes of hydrogen to trigger a controlled fusion reaction, releasing a massive amount of explosive energy.
Are nuclear bombs made with nuclear fusion?
Nuclear bombs can use either nuclear fission or nuclear fusion as the primary mechanism of energy release. Most nuclear bombs in current arsenals rely on nuclear fission reactions, while thermonuclear bombs use a fission reaction to trigger a fusion reaction.
What is necessary for the production of nuclear energy?
The number of neutrons existing in the critical core of the reactor must be steady or increasing, if it is decreasing the reaction will reduce and eventually stop. When a nucleus fissions (ie one of U-235) roughly 2.5 neutrons are produced, on average. Some of these are absorbed by the moderator and other incore materials, and some are lost at the core boundaries, but if for every nucleus that is fissioned, one neutron is then absorbed into another U-235 nucleus causing another fission, then the process will continue at a steady rate and we can call that a chain reaction. If there is a surplus of neutrons the population will increase and this could go on exponentially increasing, but this is contolled by the neutron absorbing control rods so that the neutron flux, or reactor power, is maintained at a steady level, for normal steady operation. In order for a nuclear chain reaction to take place, each nucleus must produce an average of one neutron that causes fission of another nucleus.
What is used as a trigger in a hydrogen bomb?
A traditional nuclear fission bomb is used as a trigger in a hydrogen bomb. The explosion from the fission bomb generates the high temperatures and pressures needed to initiate the fusion reaction in the hydrogen bomb.
What is shot at an isotope's nucleus to trigger a nuclear chain reaction?
neutrons
What is necessary sustain a nuclear chain reaction?
In a chain reaction, neutrons released during the splitting of an initial nucleus trigger a series of nuclear fissions.
What is the splitting of a nucleus by a slow moving neutron?
The splitting of a nucleus by a slow-moving neutron is known as nuclear fission. This process releases a large amount of energy in the form of heat and additional neutrons, which can then trigger a chain reaction in other nearby nuclei, leading to a self-sustaining release of energy. Nuclear fission is the principle behind nuclear power plants and nuclear weapons.
Does fusion reaction occur in an atomic bomb?
Yes, fusion reactions occur in a hydrogen bomb, which is a type of nuclear bomb. The high temperatures and pressures generated by the fission reaction in the bomb can trigger fusion reactions between hydrogen isotopes. This fusion reaction releases a large amount of energy, contributing to the destructive power of the bomb.
What is meant by TNT in nuclear reaction?
TNT (trinitrotoluene) is a conventional explosive used to trigger the beginning of a nuclear reaction in some nuclear weapons. When the TNT detonates, it generates the high temperatures and pressures needed to initiate the fission process in the nuclear material, causing a chain reaction to occur.
What is a neutron trigger used for?
A neutron trigger is used in nuclear fission reactions to initiate the splitting of atomic nuclei. By emitting neutrons, the trigger can start a chain reaction in which other nuclei are split, releasing more neutrons and energy. This process is fundamental to the operation of nuclear reactors and nuclear weapons.
What processes can be used to start a nuclear fission reaction in certain atoms?
Nuclear fission reactions in certain atoms can be initiated through processes such as bombarding the atoms with neutrons or by using controlled conditions that allow for the splitting of atomic nuclei. These processes can trigger a chain reaction leading to the release of energy, which can be harnessed for various applications, including nuclear power generation.
What can trigger a uranium atom to split?
It's a problem of nuclear physics - the stability of a nucleus, depending on the number of protons and neutrons.
What element is needed to make a nuclear weapon?
A nuclear weapon requires enriched uranium or plutonium as the fissile material to sustain a chain reaction and create a nuclear explosion. Additionally, a conventional chemical explosive is needed to trigger the nuclear reaction.
What is meant by chain reaction in nuclear reactor?
Basically a chain reaction (nuclear or chemical) is a self sustaining auto-catalytic reaction.In a nuclear reactor it is a neutron chain reaction, where each neutron released in every fission event can trigger another fission event. In a nuclear reactor the excess neutrons must be disposed of, which is the purpose of the control rods so that the reaction can be kept at some desired constant rate.
Hydrogen bombs and stars both produce energy with nuclear?
fusion reactions, where lighter elements combine to release tremendous amounts of energy. In stars, the fusion of hydrogen into helium powers their luminosity and heat. Hydrogen bombs use isotopes of hydrogen to trigger a controlled fusion reaction, releasing a massive amount of explosive energy.
What energy can be found in a nuclear bomb?
Electrical energy, in the triggering and fuzing mechanisms. Chemical energy, in the form of conventional explosives used to trigger the chain reaction. Nuclear energy, in the form of fissionable or fusable nuclear materials.
