Because the neutrons can continue to split uranium atoms and set in motion a chain reaction and create such intense amount of thermal energy that actually leads to the meltdown of the very mechanism that is required to harness the energy engineers at nuclear plants must absorb excess neutrons with control rods or water to regulate the rate of the reaction. In a pressurized light water reactor, the most common type of nuclear reactor, uranium fuel rods are placed in water, which slows neutrons so that fission can occur. After a fission reaction is initiated it becomes necessary to soak up the excess neutrons produced when uranium nuclei divide, so that on average only a single uranium atom from each…

In today's world where technology and advancements has flourished, majority comes to one main source to run on… Energy. There is several alternative methods on producing energy, some more efficient or safer than others. The most common and traditional source of energy in today's world is coal power, but other alternatives do exist such as that of natural gas, solar, wind, hydroelectric and nuclear energy. Nuclear energy is the 3rd most common source of our energy. Nuclear energy was first introduced in 1954 in Russia with the first power plant. Nuclear energy provides about 20% of today's electricity and does provide a substantial amount of energy, but does provide threats of radioactivity.…

Mining for elements that could be used as a nuclear power were very important in the Cold War. New technology and research for nuclear material was an essential part in building a nuclear weapon. The most important element for making nuclear weapons is uranium. Uranium is used to make plutonium, a very powerful element, by deuteron bombardment of uranium oxide. Uranium, a gray-colored element, is mined from the common uranium ores. Common isotopes, such as, radioactive sulfur (S35), radioactive carbon (C14), radioactive phosphorus (P32) and strontium (Sr90) were a great safety hazard towards the environment and mammals. The amount of time it takes for half the radioactive isotope to disintegrate is called half-life. "Isotopes with a short half-life, measured in seconds, hours, or days, are considered generally less dangerous to the envioronment2." Isotopes with a high half-life are very harmful to our world; for example, plutonium in one of its forms (Pu239) has a half-life of over 20,000 years. There is so much heat given off that, in power reactors, the heat is used to generate electricity. These nuclear elements, mainly plutonium, was used to make the most destructive weapons ever to be built: nuclear missiles.…

Scientists have discovered countless energy sources, from fossil fuel combustion to nuclear fission and fusion, each of which have seemed to pose a different problem. Whether the problematic effect seems to be cost or carbon dioxide emission, renewable and nonrenewable resources have both seemed to come with a fair set of cons with their pros. Extensive research on the topic has shown that there seems to be no flawless source of energy extraction, however there certainly are sources that are relatively worse than others. This being said, nuclear energy, from the fusion and fission of radioactive elements, is one of the worst sources of energy because of its immense waste, danger to the general public, and large expenses.…

Thorium, unlike oil, does not cause greenhouse gas emissions which would cut the world’s pollution vastly. It does not produce lethal toxins such as plutonium during usage. It is also is much more abundant than oil and we wouldn’t have to make dangerous mines to collect it. On top of that, it is completely used. LFTR’s use 98% of the fuel (thorium) they are given, this leaves only 2% that must be safely disposed of. All in all, thorium would be a much greener and a much more effective fuel.…

Not even a decade ago, our society spent years of studies in order to develop advancements in new technologies or inventions and it punctuated intervals of time in which to absorb and adapt to the change. However, in modern society, the pace of developing “the next big thing” significantly increased. Unlike the past, our modern world required shorter intervals to adapt due to our historical developments. However, there is one subject that required adaptation among our ‘big things’: Nuclear Research. The very first nuclear project in United States began in mid-1900s in order to defend our homeland and react again upcoming military threat from hostile countries in World War II. Although nuclear research in United States was started to prepare for World War II, United States has continued its research to today. However, nuclear power has had great aspect of change in our society: science, technology, economics, health care, education, politics, government, communications, travel, international relations, cultural and social trends, and other areas of society and culture.…

Nuclear power uses unstable elements like uranium. Uranium is constantly going through a process called nuclear decay, which means the atom is splitting apart over a period of time, measured in half-lives. This is why it is the element of choice for nuclear power plants. Uranium is special because it can go through what is called induced fission. Induced fission is when a free neutron is fired at an atom (like uranium). The atom will absorb the neutron, and immediately becomes unstable and splits apart. When the uranium atom splits, it will split into two separate atoms and expels two or three neutrons depending on how the atom splits. A single uranium atom, when going through induced fission, will release about 200 MeV (million electron volts). The atoms contained in one pound of uranium release as much energy as burning 1,000,000 gallons of gas. There are pros and cons of nuclear power, but is nuclear energy worth the risks?…

My element is Thorium (Th). The atomic mass number is 232.038.06 and the atomic number is 90. The melting point is 202./8 K. Thorium belongs to a group called Actinide series.Thorium is a solid at room temperature. Thorium melting point is 2028K, boiling point 5061K, and there is no freezing point. Thorium was found in 1815 by a guy named Jons Jakob Berzelius. It is used alloying agent to improve Magnesium's strength at high temperature. Thorium is also used to coat Tungsten filaments used in electronic devices, such as television. It is used to make glass with a high index of refraction that is used to make in high quality camera lenses. Thorium oxide is used as an industrial catalyst. It is also used for a source of nuclear power. It can…

Throughout the world, countries are leaning towards nuclear energy due to the amount of energy it can produce with very little resources. This topic is worth investigating since energy is basically a must, now in the 21st century. It is now considered an essential to have energy in our lives to maintain our standards of living. We have gone to many different sources of energy other than nuclear energy such as coal, solar, wind, oil and more, but many of those energy source have flaws too. Some sources of energy will reach the peak of their production due to resources and will eventually fall, others pollute the environment just like nuclear energy and some just don’t produce enough energy for us to fully rely on them. Many countries needed a new source of energy since…
