Nuclear damage is explained as any injury to or the death, sickness or disease of a person; or damage to the environment including loss of property which arises from ionising radiation associated with a nuclear installation, nuclear vessel or handling of radioactive materials. What is nuclear safety? Nuclear safety means the achievement of safe operating conditions, prevention of nuclear accidents or mitigation of nuclear accident consequences, resulting in the protection of workers, the public and the environment against the potential harmful effects of ionizing radiation or radioactive material.
Quick Links What is Nuclear Energy?
What is nuclear energy? Emergency Planning. Nuclear Security. International Cooperation. In nuclear fusion, the nuclei of atoms are joined together, or fused. This happens only under very hot conditions. The sun, like all other stars, creates heat and light through nuclear fusion.
In the sun, hydrogen nuclei fuse to make helium. The heat required to start the fusion reaction is so that an atomic bomb is to provide it. Hydrogen nuclei fuse to form helium, and in the process it releases huge amounts of energy. Atomic nuclei are positively charge, fusion to occur; they normally must collide at very high speed in other to overcome electrical repulsion. The required speeds correspond to the extremely high temperatures found in the centre of the sum and stars. Fusion brought about by high temperatures is called thermonuclear fusion that is the welding together of atomic nuclei by high temperature.
In the hot central part of the sun, approximately million tonnes of hydrogen are converted into million tons of helium each second.
The missing four million tons of mass is discharged as radiant energy. Such reactions are, quite literally, nuclear burning.

Most of the energy of nuclear fusion is in the kinetic of fragments, mainly neutrons. When the neutrons of are stopped and captured, the energy of fusion is turned into heat. In fusion reaction of the future, part of this heat is transformed into electricity. Thermonuclear fusion is analogous to ordinary chemical combustion. In both chemical and nuclear burning, a high temperature starts the reaction; the release of energy into by reaction maintains a high enough temperature to spread the fire.
The net result to the chemical reaction is a combination of atoms into more tightly bound molecules. In nuclear reactions, the net result is more tightly bound nuclei. The difference between chemical and nuclear burning is essential one of a scale. People are afraid of the consequences of nuclear as is harmful if not controlled with caution.
Since the exploding of the power plant station in Chernobyl, Russia. People are scared if the same case could happen if nuclear power plant stations are created. Although the nuclear has the consequences is still has the advantages.
Nuclear Energy Essay Examples
The nations of the world now have more than enough nuclear bombs to kill every person on Earth. The most powerful nations-Russia and United States have about 50 nuclear weapons between them. What if there were to be a nuclear war? What if terrorist got their hands on nuclear weapons? Or what if nuclear weapons were launched by accident? Some people think that nuclear energy is here to stay and we must learn to leave with it. Still others have opinions that fall somewhere in between. Nuclear energy is the solutions that ends the paradigm of consuming non-renewable fossil fuels and decreases the threats of climate change.
Although it has its consequences that are more than just a climate change but this time is about our health and if there will be a safe world if this method is followed. It may be and if it is it must be designed inherently safe and operated responsible, to avoid meltdowns and unconditional hypercritics. Article last reviewed: St.

Although, nuclear energy has a potential hazard, but it is reliable in terms of efficiency, environmental impact and cost when compared with other sources of energy. Therefore, the increase in the …show more content…. Though renewable sources of energy are reliable but their output greatly depends on the environment. For example, cloudy days have no solar gain, hence no solar energy production. Quiet days mean no wind blows to drive wind turbines.
Dams are primarily for flood control, so hydroelectricity production varies as dam water levels fluctuate. Considering the case of Aswan Dam in Egypt not only caused thousands to loose their homes and lives but also ceased the fertile surrounding because of the yearly inundation of the Nile. Moreover, the subsequent silting up for the river destroyed much wildlife.

Secondly, nuclear energy source has a weak impact on environment than the Non-renewable resources. There is no doubt that use of fossil fuels leads to global warming. While, the amount of carbon dioxide in the atmosphere was only 0.
Additionally, burning of fossil fuels, especially coal, oil, and natural gases are the main causes for increase in pollution; especially air pollution. Several hazardous pollutants are produced by fossil fuels combustion: Carbon Monoxide, Nitrogen Oxides, Sulphur Oxides and. Show More. Read More.
