Initially only the presence of a neutron source is necessary; not heating.
Nuclear fission occurs in the reactor core of a nuclear reactor. This is where nuclear fuel, typically uranium, is arranged in such a way that it sustains a chain reaction of splitting atoms, releasing energy in the process.
Nuclear reactor
The mechanism for controlled fission is nuclear reactors, which utilize a controlled chain reaction to generate heat. The container used to house this process is typically a reactor core, which contains the fuel, control rods, and coolant necessary for maintaining the fission reaction at a steady rate.
In a nuclear reactor, uranium atoms are bombarded with neutrons, causing them to split in a process called fission. This process releases a huge amount of heat energy, which is used to heat water and produce steam. The steam then drives turbines connected to generators, producing electricity.
The fission cross section in a nuclear reactor is a measure of the probability that a neutron will induce fission in a particular nucleus. It is a crucial parameter for determining the neutron flux and reaction rates within the reactor core. Different isotopes have different fission cross sections depending on their ability to undergo fission when struck by a neutron.

Control rods in a nuclear reactor regulate the rate of nuclear fission by absorbing neutrons, which are needed to sustain the fission process. By adjusting the position of the control rods, operators can control the number of neutrons available to cause fission reactions, thus regulating the overall power output of the reactor.
Control rods are made of materials that absorb neutrons, such as boron or cadmium. When control rods are inserted into the reactor core, they absorb neutrons and reduce the number available for causing fission reactions. This helps regulate the nuclear fission process by controlling the rate of reactions and maintaining a stable level of power output in the reactor.
Nuclear fission occurs in the reactor core of a nuclear reactor. This is where nuclear fuel, typically uranium, is arranged in such a way that it sustains a chain reaction of splitting atoms, releasing energy in the process.
The nuclear chain reaction in a nuclear reactor is started by the splitting of uranium atoms, a process known as nuclear fission.

Nuclear reactor
It is a process, in which a heavy nucleus is broken down in to two or more medium heavy fragments. It is used in nuclear reactor and atom bomb.
The fission happens in the fuel, which is usually in fuel rods inside the reactor. The rods are spaced at a particular distance apart and fill the reactor.
The mechanism for controlled fission is nuclear reactors, which utilize a controlled chain reaction to generate heat. The container used to house this process is typically a reactor core, which contains the fuel, control rods, and coolant necessary for maintaining the fission reaction at a steady rate.
