What else can I help you with?
Where was the first nuclear reaction?
The first chain reaction was achieved in Chicago 1942, under Enrico Fermi
What happens in a nuclear chain reaction and how does it contribute to the release of energy in a nuclear reactor?
In a nuclear chain reaction, the splitting of atomic nuclei releases energy in the form of heat. This process is controlled in a nuclear reactor to generate electricity. The chain reaction is sustained by the release of neutrons from the splitting of nuclei, which then go on to split more nuclei, creating a continuous cycle of energy release.
How has having an atomic model improved science?
the first sustained and controlled nuclear chain reaction by Enrico Fermi in 1942
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.
Do nuclear reactors have critical mass?
We know that critical mass can be achieved in a nuclear reactor. If it could not, we'd not be able to get a chain reaction and generate heat to generate power. Reactors don't have critical mass when the control rods are in, but pull the rods, start the reactor up and away you go!
Who invented chain reaction?
The concept of a chain reaction was first described by Hungarian physicist Leó Szilárd in 1933. He later patented the idea of a nuclear reactor based on a self-sustaining chain reaction. The first controlled nuclear chain reaction was achieved by a team of scientists led by Enrico Fermi in 1942 as part of the Manhattan Project.
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 artificial nuclear reactor?
An artificial nuclear reactor is a device that initiates and controls a sustained nuclear chain reaction. This reaction produces heat, which is used to produce electricity in nuclear power plants. The fission process in these reactors generates energy by splitting atomic nuclei.
What particle is needed to begin nuclear chain reaction?
Neutron particle is needed to begin nuclear chain reaction.
What particles maintain a nuclear chain reaction?
In most cases neutrons are emitted and capable of maintaining a nuclear chain reaction
What is the smallest amount of radioactive material that will support a self sustained reaction?
The smallest amount of radioactive material that can support a self-sustained nuclear reaction is called the "critical mass." This mass varies depending on the type of fissile material, such as uranium-235 or plutonium-239, and the configuration of the material. For instance, the critical mass for uranium-235 in a spherical shape is about 52 kilograms. This threshold is crucial for achieving a sustained chain reaction in nuclear fission.
What controls the chain reaction in a nuclear reaction?
