Nuclear Power :: essays research papers

Nuclear Power Producing energy from a nuclear power plant is very complicated. The process of nuclear energy involves the fission of atoms, the release of energy from fission as heat, and the transfer of heat to electricity in power plants. The process of splitting the atom is called nuclear fission. Fission can take place in many different kinds of atoms. This explanation uses Uranium - 235, the atom most commonly used in nuclear reactors. The Uranium atom has many protons, thus making it unstable. Since the nucleus of the atom is so unstable it wants to split itself apart, causing a spontaneous fission. When the nuclei of a Uranium atom splits apart, it splits into two atoms. Commonly the nucleus splits into Barium and Krypton; however, it can split into any two atoms as long as the number of protons equals the original amount of the protons found in the Uranium. In addition, a mass amount of energy is released along with two or three neutrons. It is these neutrons that can begin a chain reaction, each neutron that is given off could collide with another Uranium atom splitting it apart. Each of these fissioning atoms releases a very large amount of energy, and some more neutrons. This process continues causing a chain reaction withut any outside assistance, and the Uranium has "gone critical"(Martindale, 794-195). This chain reaction is the basis for how nuclear power is made. The amount of the energy that is given off in nuclear fission is astronomical. To equal the amount of energy given off when splitting some uranium the size of a golf ball, one would have to burn approximately twenty-five train cars full of coal. Presently, the planet contains twenty-five times more nuclear fuel compared to fossil fuel. On average, an atomic power plant can produce half a million kilowatts of power. As a comparison, a hair dryer takes about one kilowatt (Jenny, 1-2). The producing of energy from nuclear fission is very similar to using a very common fossil fuel boiler. The difference lies in the reactor, where the heat is generated by fissioning material. The most common of reactors is the pressurized water reactor; however, there are many other types. The pressurized water reactor is the most common reactor in the United States. The reactor of a nuclear power plant is where the fissioning takes place. The Uranium is contained in fuel rods, each rod is sealed so no contamination occurs. Many of these rods are then contained in a fuel assembly. All the fuel assemblies are separated by control rods. The control rods limit the amount of

The Ethical Pillars of Jainism

Jains believe that people are reborn again and again until they have freed themselves from samsara, which is the wheel of birth and death. The gradual process by which the souls learns to extricate itself from the lower self and its attachments to the material would involve purifying one’s ethical life until nothing remains but the purity is of jiva. Jains also believe that the universe is without beginning and that there is no creator or destroyer and that they can only be saved by their own efforts. They believe that the world operates by the power of nature, according to natural principles, Jains do believe in gods in demons, but as a form of humans. Jains believe in karma which is a subtle matter—minutes particle that we accumulate as we act and think. Also, Jains believe that our actions influence what happens in the future course of our life and that souls wonder until they free themselves from karma. In order to provide perfection and purification in their lives, Jains try to eliminate any false mental impressions, negative tendencies, or passions and to develop pure thoughts and actions. The three basic principles that Jains adopt to avoid accumulating karma are ahimsa (non-violence), aparigraha (non-attachment), and anekantwad (non-absolutism). Ahimsa is the non-violence principle and it is very strong in Jain teachings, and through Jainism it is influenced by Mahatma Gandhi. Jains believe that it is difficult not to harm other creature and that by simply breathing; Jains believe that tiny organisms are being killed by us inhaling them. Aparigraha is a non-attachment principle to all things and people and that people should cut one’s living requirements to a bare minimum. Possessions posses us; their acquisition and loss drive our emotions. Anekantwad, â€Å"manifold aspects† is the third principle. Jains try to avoid anger and being judgmental because that try and keep an open-mind about people by remembering that any issue can be seen from different angles.

Adoptees Have The Right Of Original Birth Certificates

My mother was adopted, along with her twin sister. Now, my mom wants to know who her parents are., bBut, there are laws preventing her from doing so. The big question in this essay is, â€Å"Should adoptees have the right to know who their biological parents are,† You could also phrase it asking the question, â€Å"Do adoptees have the right to access original birth certificates?† This question covers much more, and will be what the information in this essay circles around. This essay covers three things: adoptees have the right to access to original birth certificates because they have questions, because of equality issues, and because of the doors it opens to adoptees that have empty holes in their history. First, adoptees have the right to have access to original birth certificates because they have questions. Questions about their health, questions about who they came, who they got their blue eyes from, and other such things. As Melinda Elkins Dawson, one of 200 newborns relocated to other states for adoption in Georgia in the 50’s and 60’s says, â€Å"Every adopted child has questions.† Adoptees, especially adoptees who are older, feel empty spaces in their history, and they want to be able to fill them. â€Å"We don’t have a history. Our history begins the day we were adopted into a new family†¦ It’s important to know where you came from.† Bob MacNish says, of how not knowing your past, which makes an empty slate until you get adopted.
