Nuclear Energy

Its been awhile now~ Time has really wrapped around my throat, its the first time I had lack of sleep for two weeks straight...

Lesson learnt: You are a Leader, not a Hero~ @.@ but never the less, I still feel I could have done better in terms of letting them really understand the importance of their roles, and how it can make my life easier~

ANYWAYS Today is about NUCLEAR ENERGY!!!

I kinda like this topic and I did a presentation on it during class and HERE WE GOO~~~


Energy there are so many forms of it so I shall talk about Nuclear energy

How is it used?
How did it came about?
Advantages and Disadvantages

Then after that I shall continue with what kinds of resources that we can use asides all these in the next blog!

Nuclear Energy

There are two kinds of Nuclear energy, the first one originates from the splitting of uranium atoms in a process called fission this is man-made and the second one is sun and stars as they are inexhaustible sources which are the results of nuclear reactions converted into energy. This is natural energy. So therefore, you have two kinds, man-made and natural
Still the energy is then harnessed and regularly use to generate power.


At the power plant, the fission process is used to generate heat for producing steam, which is used by a turbine to generate electricity. Still the energy is then harnessed and regularly use to generate power.

So lets see advantages
To note, Nuclear fission is used to generate electricity does not produce soot or greenhouse gases. This also helps prevent global warming as imagine if we were to use this for the entire world @.@?.



 So as you can see in the diagram clearly stated it shows how nuclear energy are used in power plants, relatively pleasant rite? Cheap electricity for everyone. 


last but not least It reduces the countries who are dependent on foreign oil. Still compared to fossil fuels and the fuels used to power nuclear energy is very compact to fossil fuels. 


However, it is used because the fossil fuels are getting scarce. Still there are countries tat are relying too much on it. Resources are limited and fossil fuels are unsustainable. It will one day run out and thus the longevity of the survival of the necessarily limited fossil’s era will be affected. Many things that rely on such fuel will be unable to use, on the one hand by the discovery of new, exploitable resources which for most case are still developing, will aid but also strongly dependent on the price and on the other by the inevitable growth of the world’s population and their standard of living.


The fuel used to also power of nuclear reactors is very compact compared to fossil fuels. One pound of uranium can supply the same energy as 3 million pounds of coal. This makes it attractive for use in nuclear-powered vehicles like submarines, aircraft carriers and spacecraft.

Another point is that using fossil fuels The World Nuclear Association estimates that the electricity industry would add 2.6 billion tons of carbon dioxide to the atmosphere each year if it used coal power instead of nuclear.

Asides all the advantages, Nuclear energy is dangerous is many forms and it has been misused in its many ways in the history of nuclear energy 

•December 2, 1942: The Nuclear Age began at the University of Chicago when Enrico Fermi made a chain reaction in a pile of uranium.
•August 6, 1945: The United States dropped an atomic bomb on Hiroshima, Japan, killing over 100,000.
•August 9, 1945: The United States dropped an atomic bomb on Nagasaki, Japan, killing over 40,000.
•November 1, 1952: The first large version of the hydrogen bomb (thousands of times more powerful than the atomic bomb) was exploded by the United States for testing purposes.
•February 21, 1956: The first major nuclear power plant opened in England.

Disadvantages

Continuing the reasons specifically there are three point I would like to impose the concerns about the safety of nuclear fission reactors includes

Radiation-releasing nuclear accidents


•The nuclear accident at Chernobyl was the worst nuclear accident to date, spewing about 100 million
•The accident at Three Mile Island. Health effects were minimal, caused irreparable damage
•The level of public confidence in nuclear reactors for electric power production in the United States decreased.


Nuclear Waste disposal
•Radioactive waste can be in gas, liquid or solid form.

•The waste can remain radioactive and hazardous for so long.
•Finding suitable disposal facilities for radioactive waste is difficult. 
Depending on the type of waste disposed, the disposal facility may need to contain radiation for a very long time

•Depending on the type of waste disposed, the disposal facility may need to contain radiation for a very long time


Pollution also occur due to the fact companies handling nuclear waste are dumping them in rivers, seas affecting the living creatures and also humans safety and also the quality of the environment including air, soil and water supply etc. As the minor reason is due to the fact proper way of dumping cost money and this is something companies taking it into their own ways to save cost.

Nuclear weapon proliferation 

•The fuel in Nuclear reactors could be diverted for the production of nuclear weapons.

•The fuel elements know as the Plutonium could be separated chemically and diverted to nuclear weapons production.
•Security concerns about the plutonium has thus far blocked any reprocessing of fuel from nuclear power plants.
•A similar concern exists for fast breeder reactors, where the breeding process produces plutonium-239 for future generations of reactors.

Conclusion

I always believed everything has a price to pay, u wan convenience u gotta offer something in return, simply analogy. U need a car, u pay for the petrol.

But of coz we shld ask ours are this convenience really important to us?
