![]() Efficiency when it comes to energy production : It is a system that guarantees a stable and continuous supply. ![]() Nuclear fission is what currently operates in nuclear power plants around the world, so its advantages and its disadvantages are increasingly contrasted. Image from Advantages and disadvantages between nuclear fission and fusion Differences between fission and nuclear fusion The typical product of this type of phenomenon is a helium atom to which a neutron is added, a result that It derives from the combination of two isotopes of hydrogen, deuterium and tritium. Here on earth, that this reaction occurs is only possible through the application of thermal energy, or through a particle accelerator. This is the type of energy that is produced in the sun, where the pressure inside the star allows the nucleus that lead the reaction to bend the interactions. The energy produced by the Sun has this origin.įor nuclear fusion to occur, the cores of positive charge must be able to overcome the electrostatic forces of repulsion in their approach. This mass defect gives rise to a great release of energy. Nuclear fusion is a reaction in which two atoms with two very light nucleus join together to form a atom with a more stable and heavier nucleus, with a mass slightly less than the sum of the masses of the initial nucleus. The results of this reaction are that, in just a fraction of the time, the fused nucleus release an energy which is a million times larger than that obtained through other means of energy production, such as combustion through fossil fuels.įissioned nucleus release energy one million times greater than that obtained. Fission could be generated spontaneously, but it requires the existence of a neutron capable of striking the necessary energy. On the one hand, the critical mass of the fissile material must exceed a certain threshold of quantity in this material for the reaction to take place and on the other hand, the geometry of that material must also be adequate. This is a multiplier effect often referred to as a chain reaction.įor this fission chain reaction to happen, certain conditions must be met. These neutrons, in turn, can cause further fission reactions by interacting with other fissionable nucleus that will emit new neutrons, and so on. In this process two or three neutrons and gamma rays are emitted, and causes the release of large amounts of energy. ![]() These lighter atoms are called fission products. ![]() By capturing an incident neutron, that nucleus becomes unstable and splits into two nucleus of lighter atoms. Nuclear fission is the reaction that occurs in the nucleus of a heavy atom. We will begin by explaining what nuclear fission consists of. To do this, we must familiarize ourselves with nuclear fission and nuclear fusion, with the differences between the two, and with the advantages and disadvantages of using one or the other system. To understand how nuclear energy works, the first thing we must know are its processes. ![]()
