The main difference is how the water is heated to produce steam, from then on the turbines and generator work in the same way for both plants. In solid fuel, particles can only move a very short distance. Therefore the kinetic energy is converted into heat as the particles are hitting against each other.
The energy gained by splitting an atom comes from the fact that the products formed from the fission, together with the neutrons weigh less than the original product. The decay of a single Uranium atom releases on average million electron volts, the equivalent to 3. In contrast, 4 electron volts are released per molecule of carbon dioxide in the combustion of fossil fuels.
So it can be seen that this is a very compact source of energy. The reason for the large amount of energy released is because the forces involved in nuclear reactions are much greater than those involved in chemical reactions. Uranium is a very dense metal at The protons and neutrons are held very tightly together and the electrons orbiting the nucleus are comparatively far away, so this shows how the bonds involved are so much stronger.
Nuclear fission is a very efficient source of energy because of the low amounts of waste products. Combustion of fossil fuels produces waste products such as ash and toxic fumes. This reduces the amount of usable energy produced by reaction, and therefore lowers its efficiency.
Uranium is found in most rocks, at 0. The Uranium found in the earths crust contains Another possible source to extract Uranium from is seawater, the key is to find it in quantities that is economical for extraction. The reactor is contained within a concrete liner, which shields radiation.
Since the Chernobyl incident, the reactor is now usually contained within a secondary containment structure made of steel. This prevents the leakage of radioactive steam in the event of an accident. The general view on nuclear power is that it is very bad for the environment. But in reality the radioactivity released into the atmosphere by a nuclear power plant is less than that released by a coal power plant.
Additionally, coal power plants also pollute that environment with carbon and sulphur. Obviously the radiation produced by the nuclear power plant is greater in volume than that produced by the coal power plant, but the radiation is contained within the reactor.
The environmental issues with this containment are what happens to the radioactive waste when a nuclear power plant is shut down.
Half life and nuclear decay In the event of a nuclear leak, the effects of radiation on the environment can be huge. This can be seen from the after effects of the Chernobyl power plant when it exploded. This shows the large amount of time taken for radiation to be removed from the environment. The half-life of Uranium is million years, this is the time taken for half of the radioactive atoms in a sample to decay.
So it can be seen that in the event of a nuclear leak, radioactive contamination causes very long term problems. Specific attributes of this reactor were that it was a light-water-cooled graphite-moderated reactor.
This type of reactor has been criticised for its lack of containment structure, and large quantities of combustible graphite within its core. The accident actually occurred during a test run. Nuclear power, it is commonly said, holds the key to the future. Atomic or nuclear power is obtained by altering the structure of atoms. When such an alteration is made, much energy is released in the form of heat and this is used to generate electric power.
For obtaining atomic power, nuclear fission is required, which takes place in a nuclear reactor containing a heat-producing core and a cooling system. Within the core, atoms of the fuel, usually uranium, enriched uranium or plutonium, are split. The heat released by the reactor is used to generate steam and the steam is used to generate electricity.
The first nuclear power station was built in Britain in at Calder Hall. In comparison to other traditional fossil fuels as energy sources, nuclear power produces enormous amount of energy. The last argued health effect is cancer. It has been proven that no cases of cancer due to radiation occurred at less than , millirems exposure, which is a huge dose.
Back to the Hiroshima and Nagasaki, cases of cancer occurred in a carefully studied group of 80, Japanese people who were exposed to over , millirems of radiation, that is 0. Thus if we were to draw a conclusion from the Hiroshima and Nagasaki, it will be that 0.
And since the major concern is eliminated, then why not use what is considered an efficient power source that would supply us with sufficient energy? Studies show that uranium reserve in our planet earth will be sufficient to contribute to the energy production for years from now. Not only do we have an abundance of uranium for energy production, but also uranium is the most eligible, among other sources of energy, for long-term storage.
For example, a MWe -megawatts of electricity- power plant requires tones of natural uranium annually, which is easily stored. While if it was powered by coal it will require over 3 million tones of coal, that is impractical to store due to dust and visual implications World-Nuclear Association, As one might already know, nuclear power plants produce so much energy with a relatively small amount of fuel as compared to the fossil fuels powered plants. When comparing the two types of energy, scientists use the term electron volt, that is, the amount of energy an electron acquires while being accelerated by1-volt battery.
The energy in a typical chemical bond is several electron volts, whereas the fission of one uranium nucleus releases about million electron volts Ferguson, So nuclear energy is much more productive and efficient than the currently used fossil fuels. After all this, no one has any reason to reject such a clean, safe and efficient energy supply; thus, nuclear energy adoption is imperative for all countries that want to step out of the traditional, outdated and detrimental techniques that have been going on for enough time till now.
And step into a more pioneering and innovative era of clean, sustainable nuclear energy. That would last for enough generations to live without having to worry about the depletion of energy sources. Home Essays Nuclear Energy.
