The presence of neutrons in nuclei allows the strong force to overcome the electrostatic repulsion between protons. If it weren't for the presence of neutrons, there would be no atoms in the universe other than hydrogen.
Liquid sodium has been used as a coolant in fast reactors, because it does not slow down and absorb fast neutrons. It does not control the nuclear reaction directly, for that variable neutron absorbers are required.
Neutrons are subatomic particles that have been experimentally proven to exist. They were discovered by James Chadwick in 1932, and their existence is central to our understanding of atomic structure and nuclear reactions.
Nukes are called nuclear weapons.
I'm going to presume your question should have been phrased, "Is there any way to prevent the strong nuclear force from holding protons and neutrons together?" The answer is that this force is active whenever nucleons are close together, and there is no way to interfere with this force.
The force that holds protons and neutrons inside the nucleus is officially called the strong nuclear force. This is one of the four fundamental forces of the universe (the others being gravitation, the weak nuclear force, and the electromagnetic force). Scientists are still trying to work out exactly why these forces exist. It has been hypothesized that the basic forces of the universe came into being at the time of the Big Bang and are essentially a random byproduct of that event.
To produce nuclear energy an unstable element, such as Uranium 235, is struck with neutrons which causes it to decay and release more neutrons and a small amount of mass changes into energy, E=MC2. This is know as nuclear fission. The neutrons continue on and strike more atoms of Uranium causing them to decay. In the reactor are rods of Boron which absorb stray neutrons and can be either withdrawn or inserted to control the rate of the reaction. The energy released is mostly heat and is used to heat water to steam, which is then used to turn turbine generators and send power to the grid. In a nuclear weapon there is a large enough amount of the unstable element to cause what is called, "Critical mass", that is, enough for the nuclear reaction to start all by itself. It is broken into two pieces so that, until explosives slam the two pieces together, the reaction will not start. Once the pieces have collided and critical mass has been achieved, there are no Boron rods to control the reaction so, there is a run away chain reaction and all the fissionable material decays, releasing its energy.
because of the radioactive spills that been happening.
The nucleus is make up of Protons and Neutrons. These protons and neutrons are then make up of even smaller particles called quarks.Nothing has been listed as the followings. Any way nucleus would have nucleons. Mainly protons positively charged and neutrons being neutral. Apart from this there is trasaction of meson particles between these nucleons which brings, as an outcome, an extremely large attractive force called nuclear force. This nuclear force keeps the repulsive protons within a distance of the order of 10-15m
Many people mispronounce the word "nuclear" by saying "nucular" because of a process called metathesis, where sounds in a word shift their order. This mistake has been popularized by prominent figures who use the incorrect pronunciation.
Neutrons released from the fissioning, or splitting, of Uranium or Plutonium atoms collide with the molecules of the moderator, losing some of their energy in the process. This slows the neutrons down (slow neutrons are referred to as "thermal" neutrons") so that they are more likely to cause fission when colliding with another Uranium or Plutonium atom. In the most common types of reactors the moderator used is ordinary distilled water which is also used as the coolant for the reactor. Graphite and heavy water can also be used, and there are types of reactors which use no moderator at all - they operate on "fast" neutrons alone.
Because no one has been able to produce a continuous fusion reaction so far.
Because nothing to safely hold the process in has been developed yet.
