As a source of energy, nuclear energy provides a safer alternative, for the production of energy for large-scale consumption. There are two different types of nuclear energy; nuclear fission and nuclear fusion. Nuclear fission is the process in which a nucleus spits into two or more smaller nuclei. Nuclear fusion is the process in which two nuclei fuse together to form a larger nuclei. Nuclear reactors can become unstable creating an uncontrollable nuclear reaction. The effects of this can be seen in Chernobyl. Reactors have been designed safer after this disaster.
Nuclear fission is the process in which a nucleus spits into two or more smaller nuclei. Nuclear reactors use a controlled chain reaction to produce electricity. The rate at which the chain reaction occurs can be controlled by manipulating the amount of non-fissionable material present. Uranium-235 is the only naturally occurring isotope that undergoes fission. The energy released through nuclear fission is 20 million times more than the energy released burning fossil fuels. The critical mass is the maximum size a sample of uranium ore can reach. If the sample is larger then the critical mass it will start an uncontrolled reaction. 99.3% of uranium ore is made up of uranium-238 and 0.7% is uranium-235.
Nuclear fusion is the process in which two nuclei fuse together to form a larger nuclei. Hydrogen atoms are usually used in fusion reactions. Fusion releases more energy than fission but can only occur when the nuclei are very hot. The temperature needed for fusion reactions is about 20,000,000°C. Fusion reactors are also called thermonuclear reactors because of the high temperatures. Fusion occurs in three stages; in the first stage two hydrogen nuclei join to form deute...

Nuclear power provides a safer alternative for the production of electricity for large scale consumption. The two different types of nuclear reactions are fission reactions and fusion reactions. Fission reactions are the process in which a nucleus splits, forming two smaller nuclei and fusion reactions are the process in which two nuclei fuse together forming a larger nuclei. Nuclear reactors use controlled nuclear reactions to produce electricity. Nuclear energy is a more efficient energy source than any other available energy sources. The Three Mile Island nuclear disaster brought about sweeping changes in many areas of nuclear safety. Nuclear reactors have been designed to automatically shut down in the case of an earthquake.

Different Types Of Alternative Energy Essay

- Renewable energy is a type of energy source that does not have an ending to it from its consistent replenishing. Differential to fossil fuels that cause harm to the Earth, renewable energy is made from natural sources that don’t cause any harm with carbon dioxide or pollutants. There are four different types of alternative energy: nuclear, solar, wind, hydroelectric. The purpose of this paper is for the reader to better understand the use of alternative energy along with the positive and negative impacts it has on the world....   [tags: Wind power, Fossil fuel, Renewable energy]

Pros and Cons of the Different Types of Power Plants: Hydroelectric, Thermal and Nuclear Power Plants

- In developed and developing countries, sustainable energy source is the most important subject. There are many different methods of energy production and consumption. Using the cheap, abundant and clean energy sources for generating the electricity is the basic idea of production. Electrical energy is generated from different kinds of power plants. These plants can be put into three groups; hydroelectric power plants, thermal power plants and nuclear power plants. Hydroelectric power plants are used the potential energy of water....   [tags: energy source, sustainable energy, power plants]

Nuclear Power as An Alternative Energy Source Essay

- Nuclear fission is going to become more and more useful in worldwide power production for the foreseeable future. The reasons are numerous, but can be summarized by the relative ease of reliable power production that is provided. This does not go without having many disadvantages. But it is the fact that nuclear fission provides a massive amount of reliable electrical energy at a relatively low cost that has many countries investigating the possibilities of nuclear power generation. To understand why nuclear power would be the only option (at this time) for an alternative to fossil fuel burning for energy production is to understand its history, the world’s current power production from nucl...   [tags: Nuclear Energy]

Nuclear Power And Nuclear Energy Essay

- In 1789, Uranium was discovered by a German chemist. 149 years later in 1939, a German scientist by the name of Otto Hahn along, with his assistant Fritz Strassmann, discovered nuclear fission. Nuclear fission releases massive amounts of energy. But not only does it release massive amounts of energy, Nuclear fission will also release additional neutrons which can then produce fission in other uranium nuclei. Which could then turn into a self sufficient chain reaction which can produce massive amounts of energy....   [tags: Nuclear power, Nuclear fission]

Essay Nuclear Power And Nuclear Energy

- Nuclear Energy in Japan Did you know only 70 miles away from Japan’s capital city Tokyo lived a “Nuclear Valley”, encompassing more than 15 nuclear power plants. This valley was bound for success and energy delivery, until in 1999 everything went south. The Tokaimura incident is one of many nuclear catastrophes in Japan making citizens unhappy [Cont. Japan]. What is Japan’s current situation in relation to nuclear energy today. The late 1990’s was a boom in Japan’s electrical output with the help of the very first Nuclear Power plant built in the Tokai area the power plant generated up to 27.7 Billion Kilowatt hours of energy in its 2 years of up-time [ inis.iaea.org]....   [tags: Nuclear power, Nuclear fission, Nuclear fusion]

Essay about Nuclear Energy in North America

- Nuclear energy, a stable, emission free source of energy and has become a cornerstone for many countries energy needs. There are currently 463 commercial nuclear reactors producing 372,000 MWe in over 30 countries. North America produces 17% of their required energy from nuclear reactors, putting the USA 17th and Canada 21st in the world. Although this seems like a good portion, there are nine countries producing over 40% of their required power from nuclear energy. But why is a heavy energy dependent and environmentally conscious continent of North America producing such little percent of their power from a stable, emission free energy source; the very qualifications that North Americans de...   [tags: Energy]

The Negative Effects of Nuclear Energy Essay

- In 1950, the first commercial nuclear power plants were constructed. The public was promised a non-polluting and resourceful type of energy, but how safe was, and is, nuclear energy. Although there are less than 500 licensed nuclear power plants in the world, many nuclear accidents have already been endangering civilian lives. More serious accidents are not just likely, but inevitable (Fairchild 29). Nuclear energy may appear to be the ideal source of energy for the future: however, there are many negative effects of nuclear energy that can lead to very dangerous situations....   [tags: Nuclear Energy Negative Essays]

Essay about Nuclear Energy

- Radiation is a form of energy that we can find almost all around us, there are many other types of radiation that exist, some having more energy than others. Although using these materials could present danger if a great deal of exposure is released. Interaction with any exposed radiation can cause a contamination to surrounding or personal property. We use nuclear energy in what we call nuclear reactors, inside of a nuclear reactor the energy is released as heat and then used as electricity, the process that makes this electricity is fission and fusion, during fission an atomic nuclease will split into separate fragments, which will release in a form of heat and radiation....   [tags: Radiation, Nuclear Weapons]

- The discovery of nuclear energy began in the 1980’s with Rontgen’s discovery of the X-Ray soon after scientists unraveled the structure of the atom and made the discovery that all atoms have neutrons and protons. The last major component o the atom was discovered in 1932 the neutron. Another important discovery was made in 1938 Germany; the Germans were the first to carry out the fission of uranium atoms. The energy that fission created opened the possibility of two things, powerful weapons, and energy for civilian use....   [tags: Radiation, Radioisotopes, Energy]
