OTHER TYPES OF THE NUCLEAR TECHNOLOGY APPLICATIONS THAT HAVE THE POTENTIAL TO EVOLVE IN SOUTH AFRICA AND WHY THIS WOULD BE FEASIBLE South Africa as a developing country and is one of the world leader in supplying food and raw material. It has very a lot of arable land and large reserves of natural resources. The warm climate favours the production of most crops and livestock which is in demand by the population. The country’s economic backbone lies between the performance of the mining and agricultural

The disposal of nuclear waste is quickly becoming the most important issue facing the environmental community today. Nearly twenty percent of our nation’s electricity is being supplied by approximately 100 nuclear power plants that are operating in the United States. Currently‚ most of the nuclear waste created by these power plants is being housed temporarily in storage facilities and although the total amount of nuclear waste produced in one year is small‚ the need to find a permanent method

Nuclear Radiation There are many ways that the movie The Day the Earth Stood Still and the short story "There Will Come Soft Rains" are similar. "There Will Come Soft Rains" by Ray Bradbury is a science fiction story that deals with nuclear radiation and what the future world would be like if there was an atomic bomb. This short story is a good example of what could happen in the future. The Day the Earth Stood Still is a movie that also has the same genre‚ that it is science fiction. It helps

THE IMPERATIVES AND BENEFITS OF NUCLEAR ENERGY 1. INTRODUCTION Only 30 years ago‚ nuclear energy was an exotic‚ futuristic technology‚ and the subject of experimentation. Today‚ nuclear energy is America’s second largest source of electric power after coal; more than 110 nuclear energy plants supply more electricity than oil‚ natural gas or hydropower taken together. Nuclear energy is a clean‚ safe‚ reliable and competitive energy source. It is the only source of energy that can replace

In spring of 1989‚ two scientists by the name of Stanley Pons and Martin Fleischmann announced that they had found a way to create nuclear fusion in a relatively simple and cheap way. Superhot fusion is the process in which deuterium‚ a heavier form of hydrogen‚ is held within a magnetic field and heated to tens of millions of degrees. The nuclei of the atoms fuse‚ and heat energy is released. This kind of fusion happens in our solar system’s sun. This type of fusion is known to occur‚ but recreating

The instant a one megaton nuclear bomb is dropped everyone within a six mile radius of the drop site will be instantly vaporized. The people will literally not have known what hit them‚ because they will have vanished before the electrical signals from their sense organs can reach their brains. These are the people who are lucky‚ when it comes to a nuclear bombing. Those within a ten mile radius will have instantly become blind‚ and people even further away would become blind if they were looking

Transuranic elements are elements that have an atomic number greater than 92. Transuranic elements have been synthesised in nuclear reactors or in high-energy particle accelerators. Neptunium and plutonium were the first transuranic elements to be synthesised in 1940 by Glenn Seaborg’s research team in the USA. Uranium 238 is bombarded with neutrons produced by the nuclear fission of U-235. Initially an isotope of uranium (U-239) forms which decays by beta emission to produce neptunium-239. Neptunium-239

1. Why are nuclear wastes at times said to be a problem which is too complicated to solve? Radioactive wastes are wastes that contain radioactive material. Radioactive wastes are usually by-products of nuclear power generation and other applications of nuclear fission or nuclear technology‚ such as research and medicine. Radioactive waste is hazardous to most forms of life and the environment‚ and is regulated by government agencies in order to protect human health and the environment. Radioactivity
