Nuclear Fission

This topic is claimed by qmurphy3 NO3 Schatz.

Nuclear fission is the process of splitting up an atom into multiple parts. This occurs spontaneously in the form of radioactive decay.

The Main Idea

Nuclear fission is the process of splitting an atom and releasing a large quantity of energy, the primary source of all nuclear energy that is created. Nuclear fission can happen naturally in the form of radioactive decay or unnaturally with the bombardment of a nucleus with neurons. Radioactive decay is very uncommon amongst most large molecules but does happen naturally for Uranium-235 and Plutonium-239, both of which are isotopes. Uranium-235 fissions when it is bombarded by a slow moving neuron that then triggers its decay. Nuclear fission is typically managed to produce a standard and controlled reaction, but when it is not managed it results in a dangerous and uncontrollable release of energy (see atomic bomb). The two substituents that form from the split atom have a mass that is about one tenth of one percent less mass than that of the original atom, this loss of mass is about ten million times larger than the mass changes that occur in chemical reactions that involve rearrangement and do not alter or affect the nucleus.

A Mathematical Model

The large amount of energy that is released is not lost or destroyed according to the conservation of mass principle, therefore we can use the formula below to better understand the change in mass and energy released during nuclear fission reactions.

Mass of energy released = (E/c^2) = Mass Final- Mass Initial

Examples

Nuclear power plants like these are found in various countries all over the globe.

Connectedness

Nuclear fission is a very interesting topic to me because of its potential for green and renewable energy. After delving deeper into the subject, I was made aware of just how astonishingly large the amount of energy that is produced from the splitting of an atom actually was. I was always aware of what nuclear fission was because of its use in the atomic bomb and the basic explanation in secondary school. This topic however does not directly tie into my major of Biomedical engineering. The results of effective nuclear fission would be energy with which to power some types of biomedical devices as well as the potential to learn more about elements and materials that could be used in nuclear fission and other things. The overall industrial application of nuclear fission is actually quite impressive, it has the potential to be one of the most reliable and consistent forms of power production once the remainder of fossil fuels are depleted. Nuclear fission is a growing form of producing energy and will become an even better alternative once there is an adequate way to dispose of the radioactive waste that it produces.
