The fission of 1 kilogram of uranium-235, for example, produces about 2.5 million times as much energy as is produced by burning 1 kilogram of coal. Nuclear fission reactions produce incredibly large amounts of energy compared to chemical reactions. And that is just if two neutrons create fission reactions each round. These processes are summarized in the equation. If we consider option a for nucleon number conservation. Of course, each time fission occurs, more energy will be emitted, further increasing the power of the atomic reaction. Out of the given options option b is not a fission reaction. Material that can sustain a nuclear fission chain reaction is said to be fissile or fissionable. One fission will produce two atoms, the next round of fission will create four atoms, the third round eight atoms, and so on. If this process continues, a nuclear chain reaction occurs. A pressurized water reactor is cleverly designed to control the fission of large amounts of 235U, while using the heat produced in the fission reaction to. \): The fission of a large nucleus, such as U-235, produces two or three neutrons, each of which is capable of causing fission of another nucleus by the reactions shown. range of parameters presently being used in power reactors, the proportions of the fission products from uranium-235 fission may be expected to vary only.
