Nuclear reactor
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.
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.
In a fission reactor, control is implemented by inserting control rods into the reactor. These are made of a material that absorbs neutrons, and prevents a reaction from taking place.
It is different for all reactor types, but I'll tell you about the CANDU, as it is widely used, and I know the most about it. Each CANDU reactor holds 4500-6500 fuel bundles at one time, each 50cm long and 10cm in diameter, each weighing about 20kg. Each produces roughly 1GWh (gigawatt hour) of power during its time in the reactor.
explain how a fusion reactor would be similar to a fission reaction
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.

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.

yes
The rate of fission in a nuclear reactor is controlled through the use of control rods made of materials like boron or cadmium. These control rods absorb neutrons, reducing the number available to cause fission reactions, thus regulating the rate of fission. By inserting or withdrawing these control rods into the reactor core, operators can adjust the level of fission and control the reactor's power output.
