Nuclear fusion

Nuclear fusion

Nuclear fusion is a nuclear reaction through which two light nuclei of atoms, usually hydrogen and its isotopes (deuterium and tritium), are combined forming a heavier nucleus. This binding is usually accompanied by the emission of particles (in case of deuterium nuclei one neutron is emitted). This nuclear fusion reaction releases or absorbs a lot of energy in the form of gamma rays and kinetic energy of the emitted particles.This large amount of energy transforms matter to a plasma state.

The nuclear fusion reactions can emit or absorb…

Nuclear fusion reactor - ITER Project

Nuclear fusion reactor - ITER Project

The experimental fusion reactor ITER (International Thermonuclear Experimental Reactor) is a large-scale scientific experiment designed to test the feasibility of fusion as an energy source. Currently the ITER fusion reactor is under construction in the south of France, in Cadarache.

At the industry level, nuclear fusion does not exist yet. Since the 50s under investigation on the use of the energy generated in the nuclear fusion of light atoms into heavier. The development of nuclear fusion is considered very important because of the advantage offered by the large amount of energy released…

Nuclear fuel

Nuclear fuel

The nuclear fuel is the material used for the generation of nuclear energy. It is a material that can be fissionable or fused according to whether their use is nuclear fission or nuclear fusion.

We refer to both nuclear fuel material (uranium, plutonium ...) as the set made with such nuclear material (fuel rods, nuclear material compositions and the moderator or any other combination.

The best known nuclear fuel is uranium because it is the most used in nuclear fission reactors. All nuclear reactors currently in production for the generation of electrical energy are fission. At…

Differences between nuclear fusion meltdown

In a nuclear accident and the accident at the Fukushima nuclear plant in Japan, usually speaks often of the risk of core melt.

Do not confuse the meltdown of a nuclear reactor with nuclear fusion.

Nuclear fusion is the process in which two atoms are joined to form one single pass. This releases a lot of energy that could be harnessed to generate electricity. Unfortunately, these reactions can not be controlled well and much less to create nuclear power to produce electricity.

Nuclear plants currently use nuclear fission reactions, which is based precisely on the basis atom…

What is nuclear energy

Nuclear energy is the energy in the nucleus of an atom. Atoms are the smallest particles that can break a material. At the core of each atom there are two types of particles (neutrons and protons) that are held together. Nuclear energy is the energy that holds neutrons and protons.

Nuclear energy can be used to produce electricity. This energy can be obtained in two ways: nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. The sun produces energy like this. In nuclear fission, atoms are split into…

Atomic bomb

The operation of an atomic bomb is similar to the operation of a nuclear reactor, wherein the mass of fuel is well above the critical mass. Initially, the fuel is fragmented, and each of the pieces, enough from the others, so it untreated the critical size; Explosion occurs at closer fragments including sharply.

To increase the performance and efficiency of an atomic bomb to be used practically pure fuels; those used so far have been uranium-235 and plutonium-239. Uranium-235 is difficult and expensive to obtain, because it is not possible to chemically separate it from natural uranium…

Nuclear reactor

Nuclear reactor

A nuclear reactor is an installation capable of initiating, controlling and maintaining nuclear reactions (usually nuclear fission) chain that occur in the core of this facility.

The composition of the nuclear reactor is formed by the nuclear fuel, coolant, control elements, structural materials and, in the case in question a thermal nuclear reactor, the moderator.

Nuclear reactors can be classified as thermal reactors and fast reactors.

Thermal reactors are those which function by delaying (moderating) the fastest neutrons or increasing the proportion of fissile atoms.…

Advantages and disadvantages of nuclear power

In this section we analyze the advantages and disadvantages of nuclear power. Nevertheless, most organizations related to nuclear energy are already positioned for or against the use of nuclear power. On this site we try to make an objective analysis about this question, giving all the relevant information and offering a space for different conclusions.

Advantages of nuclear power

The generation of electricity through nuclear energy reduces the amount of energy generated from fossil fuels (coal and oil). Less use of fossil fuels means lowering…
