Nuclear Fusion

In the case of the sun, we get the energy by radiation. In man-made fusion, which has not been achieved yet except for a very brief moment in an experimental facility, it is hoped to get the energy which will be emitted by the gaseous plasma. Theoretically, more energy should be released than is put in to start the plasma reaction. However the actual design of a working plant is not as far as I know established yet.

Nuclear fusion. This is the process the sun uses to radiate all that light and heat.

Military use Nuclear Energy for the protection purposes and generating electricity for many military operations.Nuclear energy is used in Atomic Bomb which is becoming a necessity for every country.

The matter that is "consumed" is converted into energy, according the the equation E=mc2.

The original matter mostly becomes the final matter, though a small amount is converted into heat. The amount converted into heat is small enough however, that the larger subatomic particles are all accounted for.

We could take as an example a fusion reaction in which a deuterium atom and a tritium atom are fused into helium. Deuterium and tritium are both isotopes of hydrogen, 2H and 3H respectively. The 2H nucleus consists of one proton and one neutron. The 3H nucleus consists of one proton and two neutrons. Each atom also has one electron. The total before fusion is two protons, two electrons, and three neutrons.

After the fusion takes place, the product is one helium atom, of the isotope 4He, plus one free neutron. The 4He atom has two protons and two neutrons, plus two electrons. Thus, the total of particles after fusion is two protons, two electrons, and three neutrons. In this case, however, the helium atom and the neutron are both very, very hot.

So the number of protons, neutrons, and electrons is the same after the reaction as it was before.

The equation on converting between energy and mass is E=mc2, as you know. The amount of energy released in the fusion example above is the difference between the mc2 before the reaction and the mc2 after the reaction. While this difference in mass is so small that it is not reflected in the counts of large subatomic particles, it is nonetheless there.

The masses, in Atomic Mass units, of the atoms and the neutron are:

at the beginning

2H - 2.014102

3H - 3.016049

which add to 5.030151

at the end

n - 1.008665

4He - 4.002602

which add to 5.011267

so the difference between the masses before and after the reaction is 0.018884 atomic mass units, which represents the amount of mass converted into energy in the reaction.

The binding energy (Strong Atomic Force) released is much greater when fusion occurs than when fission occurs. As an example, that is why fission bombs typically have yields around 100 to 500 kilotons of equivalent TNT, while fusion bombs typically have yields in the 25 to 50 megaton range. The problem is that fusion requires a lot of energy to initiate - in fact, most fusion bombs use a fission bomb to set them off.

Triple fusion is a process in plants where three individual nuclei from the male gamete (pollen) join together with two nuclei in the female gamete (ovule) during fertilization. This results in the formation of a triploid cell which eventually develops into the endosperm of the seed, providing essential nutrients for the growing embryo.

In the sun, nuclear fusion occurs when hydrogen atoms combine to form helium. This process releases a large amount of energy in the form of light and heat. The immense pressure and temperature at the sun's core enable this fusion reaction to occur, sustaining the sun's energy output.

It's hard to compare the two because of the variety of fuels, and the corresponding variety of fission and fusion reactions. Currently we can't do fusion in a reactor like we can fission. That makes it hard to compare, too.

Roughly speaking, however, you'd get around 4x more energy per unit mass of fuel out of fusion. This is comparing the fusion of deuterium and tritium to Helium, with the fission of U(235) to Rb(90) and Cs(143).

Compared to the total energy in the fuel (i.e. a matter/antimatter annihilation reaction) even the fusion reaction only liberates about 0.4% of the total energy.

It is technically challenging to create these reactions safely and efficiently.

Nuclear fusion releases energy in the form of heat and light. This occurs when the nuclei of two atoms combine to form a new, heavier nucleus, releasing a large amount of energy in the process.

~ Shin: In Gant. In the largest house at the top, you'll find a hole in the wall badly disguised by a drawer. Shove it aside and you'll find a mentor on the other side.

~ Debo: In Gust. Inside the flutemaker's house, look where the two barrels and the box is. Move aside the box to fall down the hole, and then solve the barrel puzzle to get to the other side.

~ Doof: From Camelon, head north-east across the two bridges. Instead of going down the ramp to the where Nanai was, head up to the dig patch and use Mogu on it.

~ Puka: In Bleak. In the house behind the Dragon Shrine, there are two big boxes that can be moved by Doof. One houses the item, but if you move the top stack of boxes, you'll fall down a hole where the mentor is.

Hope this helped!

True. Heat produced by nuclear fusion in the core of stars causes them to shine brightly and emit light and heat into space.

Intertransverse fusion is a surgical procedure where the transverse processes of two adjacent vertebrae are fused together using bone grafts or implants to stabilize the spine after injury or degeneration. This fusion restricts movement and can help alleviate pain in certain spinal conditions.

The primary gas produced by nuclear fusion is helium. In the Sun, hydrogen nuclei fuse to form helium nuclei, releasing large amounts of energy in the process. Helium is a byproduct of this fusion reaction.

The main purpose of the hydrogen bomb was to create a much more powerful and destructive nuclear weapon than the atomic bomb. It was designed to release energy from nuclear fusion reactions, which is many times greater than that of nuclear fission reactions used in atomic bombs.

The element is hydrogen. The easiest reaction to produce on earth (though still very difficult) is between deuterium and tritium. Deuterium is hydrogen with one proton and one neutron, tritium has one proton and two neutrons. Deuterium (heavy water) can be separated from ordinary water whilst tritium has to be made from lithium in a nuclear reactor, and it is radioactive with a half life of 12 years so it does not occur in nature.

It has been calculated that it would take roughly 8 years from the end of fusion in the core to the surface of the sun beginning to cool. It would then take 8 minutes before we would notice this cooling on the earth.

These are the fission products, they are lighter elements formed by the splitting of uranium 235 nuclei into two pieces. The process produces a range of pair combinations, not always the same pair, but there are two peaks of resulting atomic number nuclei. Many of the fission products are intensely radioactive, and so dangerous, but they are contained within the fuel and its zircaloy sheath, and so long as this is intact they can be controlled safely. It is only if the fuel sheath is damaged that the active products can escape, but even then they will not leak to atmosphere unless there is also a leak in the primary reactor circuit.

The duodenal ampulla is formed by the fusion of the pancreatic duct (duct of Wirsung) with the common bile duct (duct of the liver). This union occurs at a structure called the hepatopancreatic ampulla (ampulla of Vater).

energy through processes like nuclear fusion, as described by Einstein's famous equation E=mc^2. This process is seen in stars where mass is converted into energy, releasing huge amounts of light and heat.

Two different isotopes of hydrogen form an isotope of helium on the sun

Fission power is the only realistic source of ecologically sound power, for at least the next 50 to 100 years.

Massive stars cannot generate energy from iron fusion because iron fusion does not release energy, rather it absorbs energy. Iron is the most stable element, and fusion of iron requires more energy than it produces, making it an unfavorable process for generating energy in stars. This leads to the collapse of the star's core and triggers a supernova explosion.

Nuclear fission is the process of splitting a nucleus with a large mass into two nuclei with smaller masses. The energy released can then be used to produce electricity. Nuclear fusion is the process of merging nuclei with smaller masses into a nucleus with a larger mass. The energy released by this reaction may someday be used to produce electricity. In other words, Nuclear Fusion is the exact opposite of Nuclear fission. While Nuclear Fission is splitting a nucleus into two nuclei, nuclear fusion is merging two nuclei into a nucleus.

In the Sun and other stars, the fusion reactions occur under enormous pressure and incredible heat. These conditions cannot be replicated on Earth.

However, a reasonable facsimile of the fusion reaction can be simulated by using hydrogen and lithium compounds, and applying a short burst of concentrated energy (usually by lasers). This theoretically can force an implosion that for a brief moment provides the necessary particles, heat, and pressure to intitiate fusion.

So far, no fusion reactions have generated more energy than they required.
