= __What are Nuclear Fission Reactors?__ =
 * In nuclear fission, the reactor has a nucleus of an atom, usually uranium that extends or breaks a nucleus into two parts of lighter nuclei into a variety of particles, such as protons, neutrons, or alpha particles or by using electromagnetic radiation in the form gamma rays.
 * The process of a nuclear fission reactor is to have a large quantity of energy be released which will form radioactive products and emit several neutrons. The emitted neutrons can cause fission in the nucleus of fissionable material, which releases more neutrons that will continue the cycle of fission. If used in a controlled reaction, this chain reaction can power cities to the benefit of society. However, uncontrolled reactions, such as those found in an atomic bomb, can lead to an explosion of tremendous destructive force.

= __ What are the Fundamentals of Nuclear Fission? __ =
 * The process of nuclear fission is the structure and stability of nuclear matter. The reason why nuclear fission can undergo the process of structure and stability is because the nucleus contains nucleons, which have the inside of an atom called a neutrons and protons. For example, the total atomic number of an atom is equal to the total mass number of a nucleus.
 * The actual mass number is always less than the sum of the mass inside the neutrons and protons.
 * The law of conservation of mass of energy has a small amount of mass m being converted into a large amount of energy by the famous equation developed by Einstein, E = mc^2, where c is the velocity of light in vacuum. For instance, in a nuclear fission or fusion reaction, a large amount of energy is released.
 * Therefore, the law states that energy cannot be created or destroyed.

__How are Fission Reactors Used?__
= __How are the nuclear fission chain reactions made and how they are controlled?__ =
 * A nuclear fission reactor is essentially a furnace that produces steam or hot gas that can provide heat that is transferred directly or driven through turbines to generate electricity.
 * A nuclear reactor can be used to generate electric power for cities, but it can also generate power for propelling submarines and certain kinds of surface vessels.
 * Another thing a nuclear reactor can do is the utilize the high neutron fluxes for studying the structure and properties of certain materials, which can have many different applications
 * However, heat can generated from the radioactive decay of an element can be converted into electrical energy through semiconductor materials, which will produce a nuclear battery.
 * Several neutrons are emitted at the start of the fission process.This lead to a possible chain reaction if one of the fission neutrons can induce fission in a fissile nucleus.
 * This will cause the nucleus to undergo fission and will also emit more neutrons in order to continue the chain reaction.
 * Therefore, this is expressed as multiplication factor, //k//, which is the ratio of the number of fissions produced in one step, or in neutron generation, in the chain to the number of fissions in the preceding generation. If //k// is less than 1, the chain reaction can't be sustained. If //k// is greater than 1, the number of fissions will increases at each step. If //k// equals 1, a steady chain reaction can be maintain.

__**What are the controversies? **__
 * Conclusion: **
 * An accientds may lead to leaking radioactive materials such as plutonuim. The unauthorized experiments may also cause a great hazards to an nuclear power planet.

The place such as the Yucca Mountians cannot ba a safeplace for the storge or nuclear waste because placing these materials can have cause in the soil and water.
 * <span style="font-family: Times New Roman; font-size: 14pt; margin: 0in 0in 0pt; tabstops: list .5in; tabstops: list .5in;">Uranium and plutoium may also be used in making atomic bomds.Therefore, we also need to make sure that these materials are well-protected and controlled.
