One of the major problems of nuclear energy is the inability of scientists to discover a safe to dispose of the radioactive wastes which occur throughout the nuclear process. Many of wastes remain dangerously active for tens of thousands of years, while others have a life span closer to a quarter of a million years. Various methods have been used to date, but all have revealed weaknesses, forcing scientists to continue their search The nuclear fuel rods are installed in the reactors, where they remain until the accumulation of wastes becomes such that the fuel is no longer usable. The "used" fuel is then sent to a processing plant, where the radioactive wastes are removed; the remaining uranium is sent to a hemical plant to start the fuel cycle over again. The radioactive wastes are sent to be stored or buried. The nature of these wastes together with their lengthy life span has made it extremely difficult for scientists to find a way of disposing of them safely and permanently The United States attempted to bury much of its radioactive waste material in containers made of steel covered in concrete and capable of holding a million gallons. For a long time it was believed that the nuclear waste problem had been solved, until some of these tanks leaked, allowing the radioactive wastes to seep into the environment. Canada presently stores its nuclear waste in underwater tanks, with the long-term effects largely unknown. However, plans are under consideration for above-ground storage of spent fuel from reactors. These plans include the building of three vast concrete containers, which would be two stories high and approximately the length and width of two football fields. Other suggestions include enclosing the waste in glass blocks and storing them in underground caverns, or placing hot containers in the Antarctic region where they would melt the ice, thereby sinking down about a mile. This idea has since been abandoned because of the possible adverse effect on the ice sheets The problem of what to do with atomic waste, the harmful unwanted products of atomic energy, is being studied by many scientific minds Large atomic reactors produce harmful radioactive lements at the same time that they produce energy. The atomic waste is so powerful that it will be a danger for centuries. What can be done with it? Where can it be placed so that it will not harm human beings? No one now has the fianl anwer, but hundreds of scientists are searching for it What would you do with radioactive atomic waste? Mix it with water and pour it in the ocean? You would not do that if you lived near the water. a box the size of a package of cigarettes would hold the radioactive waste produced by an atomic reactor in five minutes. If you poured it into a body of water more than one hundred miles long and about fifteen miles wide, this small amout of atomic waste could be discovered by a Geiger counter anywhere within its harbors and bays in less than twenty-four hours. This shows the great size of the problems of what to do with atomic Atomic waste cannot be burned, boiled away, or made harmless by mixing it with other minerals. We are not working with a substance that can be destroyed. We are trying to destroy energy, and that is impossible. The only thing we can do is to keep the waste in a place where it will be harmless Throwing it into the ocean is one method that has been tried. Atomic waste is placed in metal barrels that are then put in containers as thick and strong as stone. The cases are taken to thethe deepest part of the ocean and thrown in. For several reasons, however, throwing the atomic waste into the ocean is not a final answer to the problem
