Nuclear energy has benefits and disadvantages, but taking uranium and turning it into a source of power creates many options for nuclear power. Function The majority of nuclear energy is used to create electricity. First, uranium must be stored and separated into two different elements using an enrichment process. The elements are then brought through a chain-reaction fission process that splits the atom in two. Heat energy from the fission boils water and creates high-pressured steam that powers a turbine connected to a generator. The generator spins and creates the electricity that can be used.
Features A small percentage of nuclear energy is used for things other than electricity. A few ships and submarines are nuclear powered in order to help the ships during war situations. This is a small percentage and not a future concept that will be explored. Certain countries use nuclear power more than other countries. France is powered 80 percent by nuclear power, eliminating the need for a majority of fossil fuel burning factories for which they would have to import coal and other fuels. Benefits Using nuclear energy has many benefits. One of the main benefits is that nuclear plants emit no CO2 or pollution into the air. Uranium that has gone through fission also lasts about three years before new uranium is needed in each section of the reactor. This helps the element last longer because it is nonrenewable.
Effects Use of nuclear energy also comes with some harmful effects. All of the water that is steamed to power the turbines becomes radioactive and this can be harmful to humans. The process of creating nuclear energy also creates nuclear waste that needs to be stored. If it is not properly stored then radiation can spread, causing harm to living things, mutations and potentially death. Psychological Disorders A biological effect of nuclear radiation is the increased risk of developing psychological disorders. This includes both short-term and long-term mental disorders. Some of these psychological disorder include major depression, generalized anxiety disorder and post-traumatic stress disorder. Cancer Being exposed to nuclear radiation does not directly cause cancer. However, this exposure does greatly increase a person's risk of developing cancer, according to the Mayo Clinic. This biological effect of nuclear radiation can increase a person's risk of developing any type of cancer. However, the most common cancers associated with nuclear radiation exposure include leukemia, stomach cancer, breast cancer, multiple myeloma, bladder cancer, ovarian cancer, liver cancer, esophageal cancer and lung.
Potential If nuclear energy is properly used and stored then it can become a leading source of power to the world without harming the environment from pollution and emissions. The use of nuclear energy could also be explored for the expansion of more ships and possibly automobiles. Hazards The biological effects of nuclear radiation can be devastating to human and animal life. Humans who are exposed to nuclear radiation can experience radiation sickness, also referred to as acute radiation syndrome, acute radiation sickness or radiation poisoning. According to the Mayo Clinic, radiation sickness is very rare, but it is also very serious and in most cases fatal.
Signs and Stages There are four stages of radiation sickness: mild, moderate, severe and very severe. The stages depend on how much nuclear radiation a person has absorbed. During the moderate stage a person may experience nausea and vomiting within 48 hours of exposure, along with weakness, fatigue and headache. During the moderate stage a person may experience nausea and vomiting within 24 hours of exposure, delayed wound healing, fever, blood in the stool, hair loss, blood in vomit and infections. The moderate stage can be fatal in those who are very sensitive to nuclear radiation. During the severe stage a person may experience nausea and vomiting within an hour of exposure, high fever and diarrhea. The severe stage is fatal in approximately half of all people who experience it. During the very severe stage a person may experience almost immediate nausea and vomiting, low blood pressure, disorientation and dizziness. The very severe stage is almost always fatal.
Utilization of nuclear waste Now, a team led by an Indian scientist has developed a new method to reduce the amount of this waste considerably. The disposal of the old core rods and also reactor operation results in a large amount of low-level waste, especially contaminated cooling water. S. Narasimhan from the Bhabha Atomic Research Centre in Kalpakkam, India working with P.D. Börje Sellergren, a chemist from the Institute of Environmental Research Technische Universität, Dortmund in Germany, developed the method. His approach: small beads consisting of a special polymer which ‘fishes’ the radioactivity out of the water .
Preventing from radiations Fallout Shelters Fallout shelters are designed to provide a secure location -- often underground or at least partially underground -- where you can avoid all or most of the radiation from fallout -- tiny irradiated particles that rain down from the sky after a nuclear explosion. Fallout shelters rely on earth, sand, cement, brick, cement block or other dense material to block the radiation until it lessens due to the half life. A shelter should, at the minimum, allow only 1/40th of the radiation to get through, and designs that block all but 1/100th or 1/250th more are superior. The better the shielding, the safer you will be.
The grey area is that we need to still define a mechanism to prevent environment from global warming and human beings from radiation. The other alternative is to use alternative energies For more information checkout the link below http:// igutek.scripts.mit.edu/terrascope/?page =Alternative Regards, Shiphali Valecha
