Nuclear power plants use fission reactions to generate electricity by splitting uranium atoms. Nuclear weapons also use fission reactions to release a large amount of energy in the form of an explosion.
An atomic bomb uses a nuclear fission reaction. This involves splitting the nucleus of a heavy atom, such as uranium or plutonium, into smaller nuclei, releasing a large amount of energy in the process.
The hydrogen bomb uses nuclear fusion, a reaction in which two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy. This differs from nuclear fission, which is the process used in atomic bombs where heavy atomic nuclei are split into lighter ones.
Fission does not respond to changes in temperature and pressure like chemical reactions do. In a nuclear reactor, the fission chain reaction can be sped up by removing rods of cadmium, which absorb neutrons. These are in place to prevent the reaction from occurring too quickly. Remove them, and the chain reaction may proceed out of control.
Non-radioactive elements can undergo fission reactions, but they are typically not used in nuclear power plants because their fission tends to require high-energy neutrons, which are more easily produced in reactions involving radioactive elements. However, non-radioactive elements like uranium-238 can undergo fission in certain reactor designs.
The most powerful type of nuclear bomb is the hydrogen bomb, also known as a thermonuclear bomb. These bombs use a two-stage process, with an initial fission reaction triggering a fusion reaction, resulting in a much larger explosion compared to atomic bombs.
The fission reaction is controlled through use of high neutron capture material as Boron, Gadolinium, Cadmium, ... etc.

The difference between the use of fission and fusion as an energy source is that in fusion reaction, 2 or more light atomic nuclei fuses to form single heavier nucleus while in fission reaction, heavy atomic nucleus is usually splited into smaller nuclei, other particles and radiation.
Nuclear bombs can use either nuclear fission or nuclear fusion as the primary mechanism of energy release. Most nuclear bombs in current arsenals rely on nuclear fission reactions, while thermonuclear bombs use a fission reaction to trigger a fusion reaction.
Fission is splitting of atoms into two parts.We use Fission to make light and heat for Earth.We use Fission sometimes for medicine.Fission is located in the middle of the Star.Have less energy than Fusion.Nika S.S.
To some degree. Hydrogen bombs release energy via nuclear fusion, but they use a fission reaction to trigger the fusion.
A moderator in a fission chain reaction is a system (usually water) that slows neutrons down (decreases their energy) to the point where they can interact with fissile material, causing the fission reaction to be self sustaining. This is necessary because, without the moderator, the neutrons emitted from fission have too much energy to cause subsequent fission. The design of the moderator is such that it provides automatic control of the reaction. As it heats up, the moderation effect decreases, causing the reaction to decrease. Conversely, as it cools down, the moderation effect increases, causing the reaction to increase. In the event that the moderator fails, such as when a depressurization event causes the water to flash to steam, the loss of moderation causes the fission reaction to stop.
In general, however, a nuclear fission reaction involves the fissioning (or splitting) of heavy atoms (heavy, as in greater than lead, due to the binding energy curve), which results in release of some of the binding energy that was used to sustain the un-fissioned combination. Also, depending on which nuclide is fissioned, extra neutrons result, and these neutrons can (under the right conditions) go on to fission more atoms, in a process called criticality, or, simply, a nuclear fission chain reaction.
The hydrogen bomb uses nuclear fusion, a reaction in which two light atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy. This differs from nuclear fission, which is the process used in atomic bombs where heavy atomic nuclei are split into lighter ones.
It isn't, in general. Thermonuclear bombs use a fission bomb to generate the heat and pressure required to start the fusion process, but there are other ways of doing it (stars do so by gravity, for instance).
bacteria, protozoa, algae, amoeba
There are both controlled and uncontrolled fission reactions. The reactors in nuclear power plants and submarines make use of a controlled nuclear reaction. Nuclear weapons make use of an uncontrolled reaction.
