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.

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 fission occurs in fission reactors, a type of nuclear reactor, and in fission bombs, more commonly knows as atomic bombs.
It is a device where a controlled nuclear fission chain reaction occurs.
Nuclear fission is the primary type of nuclear reaction that occurs in a reactor. It involves the splitting of heavy atomic nuclei to release energy.
After nuclear fission occurs in fuel rods in a nuclear reactor, the next step is to control the reaction by regulating the rate of fission through control rods. These control rods absorb neutrons to maintain a steady and safe level of nuclear chain reactions in the reactor core.
Nuclear fission occurs in the core of a nuclear reactor, where the energy released from splitting atoms is transformed into heat energy. This heat is then used to generate steam, which drives turbines to produce electricity.
The part of a nuclear power plant that undergoes a fission reaction is called the reactor core. This is where the nuclear fuel, such as uranium or plutonium, is housed and where the chain reaction occurs to produce heat energy.
The main reaction that occurs in a nuclear reactor core is nuclear fission. In this reaction, the nucleus of an atom is split into smaller parts, releasing large amounts of energy in the form of heat. This heat is then used to generate electricity in the reactor.
We might think of induced nuclear fission as a fission reaction that occurs when a neutron is captured by, say, a uranium-235 atom and that atomic nucleus undergoes fission as a result. Most all of the fission events within a nuclear reactor or nuclear weapon are induced. Given this, we might then compare that fission event to a spontaneous fission event wherein the atomic nucleus of a uranium-235 atom spontaneously undergoes fission without having captured a neutron.
Inside a nuclear reactor, controlled nuclear fission occurs. This process produces heat, which is used to generate steam. The steam then drives turbines connected to generators, producing electricity. Heat removal systems and control mechanisms are in place to regulate the reaction.
A nuclear reactor primarily emits electromagnetic radiation in the form of gamma rays. These gamma rays are released during the nuclear fission process that occurs in the reactor core. Additionally, reactors may also release some neutron radiation through reactions with the reactor's components.
