  • Chernobyl - 1,198 words
    Chernobyl April 26th 1986 marked the date of the worst nuclear accident to ever occur. Chernobyl, a nuclear power plant in Russia was undergoing routine safety tests that envolved running the reactor on less then full power, followed by a standard shut down. At Chernobyl's reactor number 4 a specific test was designed to show that a coasting turbine could produce enough power to pump coolant through the reactor core while waiting for electricity from diesel generators. During the test turbine feed valves were closed to initiate turbine coasting, and automatic control rods were withdrawn from the core. When the steam valves to the turbine close, the pressure in the reactor should go up causin ...

Large scientific and epidemiological research programs, some of them sponsored by international organizations such as the WHO and the EC, are being conducted to provide further insight into possible future health effects. However, the population dose estimates generally tend to indicate that, with the exception of thyroid disease, it is unlikely that the exposure would lead to discernible radiation effects.

  • Chernobyl - 1,436 words
    Chernobyl The Chernobyl disaster on April 26, 1986 is described as one of the most frightening environmental disasters in the world. The plant was made up of four graphite reactors, which were the most modern Soviet reactors of the RBMK-type. Two more of these reactors were still under construction at the station. Chernobyl was an obscure town in north central Ukraine (former Soviet Union) on the Pripyiat River near the Belarus border. Immediately its name was joined to the Nuclear Power Plant located twenty-five kilometers upstream. The plant is actually located fifteen kilometers northwest of the city. It is not only the radioactive mess left that strikes fear. Nineteen similar stations ar ...

  • College Choosing - 969 words
    College Choosing Choosing a college during the final years of high school can be a long strenuous process, full of many lifelong decisions. These decisions can be broken down into six categories. The categories are cost, entrance requirements, location, living arrangements, unique programs, and extracurricular activities. The University of Missouri St. Louis and the University of Missouri, Columbia have some similarities yet many more differences. A major concern when deciding which college to attend is cost. Cost consists of not only tuition but also books, room and board. If one would like to attend the University of Missouri, Columbia for a residential student the composite cost for tuiti ...

  • Fusion - 1,354 words
    Fusion Fusion reactions are inhibited by the electrical repulsive force that acts between two positively charged nuclei. For fusion to occur, the two nuclei must approach each other at high speed to overcome the electrical repulsion and attain a sufficiently small separation (less than one-trillionth of a centimeter) that the short-range strong nuclear force dominates. For the production of useful amounts of energy, a large number of nuclei must under go fusion: that is to say, a gas of fusing nuclei must be produced. In a gas at extremely high temperature, the average nucleus contains sufficient kinetic energy to undergo fusion. Such a medium can be produced by heating an ordinary gas of ne ...

    ... eating, and the onset of nuclear fusion. The situation in star formation differs in one respect: after gravitational collapse ceases and star begins to expand again due to heat from exoergic nuclear fusion reactions, the expansion is arrested by the gravity force associated with the enormous mass of the star. In a star a state of equilibrium in both size and temperature is achieved. In ICF, by contrast, complete disassembly of fuel occurs. The fusion reaction least difficult to achieve combines a deuteron (the nucleus of the deuterium atom) with a triton (the nucleus of a tritium atom). Both nuclei are isotopes of the hydrogen nucleus and contain a single unit of positive electric charge ...

  • Fusion Energy - 860 words
    Fusion Energy A fusion reaction is one in which two atomic nuclei merge to form a heavier nucleus. this is the process that happens in in the stars. In average stars, like the sun, the process of fusion is converting hydrogen nuclei (or protons) into helium nuclei. There is an enormous amount of kinetic energy and gamma rays released in this process that heat the star's interior, and this realease is what maintains it at the extreamly high temperatures (greater than 10 million K) required to continue the fusion. This process has been making the stars go for billions of years has clear potential as a power source on earth. Once we have started the reaction, Fusion requires no energy and reale ...

  • Fusion: Our Futures Energy - 969 words
    Fusion: Our Future's Energy? Fusion energy seems to be the most promising energy source of the not-too-distant future. It is safe, it uses an energy supply that is so abundant that it will never run out, it gives off harmless waste, and it produces energy comparable to the Earth's sun! But are there any problems with this hopeful energy source? What is Nuclear Fusion? To understand fusion, it is a good idea to know about fission. This is the splitting of the nuclei of atoms into two or more smaller nuclei by bombarding them with neutrons of low energy. It was discovered in the 1930's in an attempt to make transuranium elements (elements with atomic numbers greater than Uranium that do not ex ...

  • History Of Physics - 1,315 words
    History Of Physics Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist, and the first Greek philosopher. He was an astronomer, merchant and mathematician, and after visiting Egypt he is said to have originated the science of deductive geometry. He also discovered theorems of ...

  • In Civilization There Have Been Few Individuals That Leave A Legacy Of Ideas That Have Impacted On Society Forever Albert Ein - 1,493 words
    In civilization there have been few individuals that leave a legacy of ideas that have impacted on society forever. Albert Einstein the German-born scientist was one of the gifted few. Despite being one of the greatest thinkers ever to grace the world with his presence, Einstein flunked out of grade school miserably (Poole). He was a terrible English student, because of his poor grammar skills (Poole). At one point a teacher actually told Einsteins parents that he was mentally challenged. He was actually recommended for "special classes"(Brown). His parent did not believe this, they could see that he was different, but far from mentally challenged. There perseverance was soon proved well wor ...

  • Manhattan Project And The Abomb - 1,664 words
    Manhattan Project and the A-Bomb Just before the beginning of World War II, Albert Einstein wrote a letter to President Franklin D. Roosevelt. Urged by Hungarian-born physicists Leo Szilard, Eugene Wingner, and Edward Teller, Einstein told Roosevelt about Nazi German efforts to purify Uranium-235 which might be used to build an atomic bomb. Shortly after that the United States Government began work on the Manhattan Project. The Manhattan Project was the code name for the United States effort to develop the atomic bomb before the Germans did. "The first successful experiments in splitting a uranium atom had been carried out in the autumn of 1938 at the Kaiser Wilhelm Institute in Berlin"(Grou ...

  • Methanol As Fuel - 519 words
    Methanol As Fuel This section is about methanol fuel cells for our future. Since I have done this research I have never realized how important future fuels are. Methanol is a liquid fuel made form natural gas or renewable biomass resources. Methanol is the leading candidate to provide the hydrogen necessary to power fuel cell vehicles. The commercialization of methanol-powered fuel cells will offer practical, affordable, long-range electric vehicles with zero or near zero emissions while retaining the convenience of a liquid fuel. By 2004 they say or even sooner, fuel cells operating on methanol will power a variety of cars and buses in the U.S and worldwide.( Methanol is pr ...

  • North Korea - 3,011 words
    North Korea The United States has been presented a dilemma towards its foreign policy with the Democratic Peoples Republic of Korea (North Korea). North Koreas alleged launch of a new Taepo-Dong I missile on August 31, 1998 has heightened American worries and escalated an already tense situation with North Korea. The United States response towards this new missile, which could possibly be able to reach the edges of both Alaska and Hawaii , will be a factor in its decision on whether or not to continue to finance support towards North Korea. New sanctions could mean the collapse of a weak North Korean economy. Already on the brink of economic and political collapse, the loss of U.S. and KEDO ...

  • Nuclear Bombs - 1,087 words
    Nuclear Bombs THE FIRST DESIGN of a nuclear weapon in the United States was a gun-barrel assembly, in which two sub-critical masses of very highly enriched uranium (HEU), were brought together by normal artillery propellant in a short gun barrel into a single over-critical configuration. (Criticality defines the minimum amount of a fissionable material in a particular configuration and density capable of a self-sustaining chain reaction). The second type of fission weapon is the implosion assembly, in which a high explosive (with a much faster detonation speed than the propellant used in a gun-type weapon) compresses fissile material so that it reaches a super-critical mass. Less fissile mat ...

  • Nuclear Energy - 1,925 words
    Nuclear Energy From Theory to Practice The nuclear age began in Germany, in the 1930s in the lab of chemist Otto Hahn. Hahn was attempting to produce radium (In great need during the war) by bombarding uranium atoms with neutrons. To his surprise, he ended up with a much lighter element, barium. That was 1938, This started the race for the power of the atom. Just four years later Canada entered nuclear age in cooperation with the british. Wartime, 1942: The British wanted a safe place to conduct nuclear experiments; Since their country feared invasion by the nazi's or bombing attacks, Canada provided the haven the british needed in return for a opportunity to work in the project. The leader ...

    ... uld then conclude that the nuclear industry is mostly to blame for the nation wide increase of cancers and deaths. Is the nuclear industry really benefitting the nation or is it just making the world into a radioactive dump which takes thousands of years to clean up? One last major problem with nuclear energy that needs to be touched on is the storage of nuclear waste. Nuclear waste includes all contaminated parts that have had contact with any source of nuclear energy and all products of a nuclear reaction that was discussed at the beginning of the paper. There are several problems that relate to the storage of nuclear energy. At a nuclear storage facility, there are security officers, ...
