Introduction………………………………………………………..3 Chapter III When we discovered nuclear energy, we found the power to produce more weapons. If you want to learn more about nuclear energy , nuclear energy sources, and its uses, check out this three-part YouTube series. Since then human have begun expanding their research on nuclear energy and sadly during year 1939 to year 1949, nuclear energy was only used for creating atomic bomb by many of the countries back then such as Japan, Germany, United States of America and etc. plants were constructed. These materials can remain radioactive and dangerous to human health for thousands of years. While nuclear power is much in the news right now because of the recent accident in Japan. section of "resource availability and waste", and the other "the continuity of Only a few countries have uranium ore, which means that a tiresome process of getting the approval of several international authorities is required before anyone can build a nuclear power plant. This was demonstrated in the recent Fukushima daiichi nuclear reactor crisis wherein the reactors as of March 24, 2011 at Fukushima emitted 30,000 to 110,000 TBq of Iodine 131 much higher compared to Chernobyl’s 760 PBq or 400 kg of I-131, 85 PBq Cs-137 (Shimbun, 2011). 1 nuclear plant disaster has made Japan reconsider the role of nuclear power in its future. Nuclear power stations are designed to work in a multiple-step process to help contain the energy and the many negative byproducts that result from this process. Its effects can still be observed today, three decades post the incident. On top of that, the people living nearby the potential site usually oppose the project. A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. She is also going to conduct interviews and surveys about the opinions of different people. However, before we can have a view on the matter, we must know all the pieces of the puzzle. it is a major source of man-made repercussions as well as being the basis of Unlike non-renewable energy sources, such as coal or natural gas, nuclear power plants do not emit global warming emissions while operating. Coal was next in line with 26%, then Nuclear radiation arises from hundreds of different kinds of unstable atoms. After the uranium splits to generate heat, the resulting byproducts are a radioactive material, which means workers need to conduct waste disposal in a safe way. Difficult to manage: Nuclear energy can have a After a nuclear meltdown though, the large doses destroy living cells and cause mutations, illness, and death. As we said before, this is a scarce resource and in limited supply. Gamma rays and neutrons can produce harmful effects in living organisms, a hazard that persists over considerable distances because of their ability to penetrate most structures. We cannot call Uranium a renewable source or a renewable energy due to its limited supply and hazardous effects. However, after the shutdown, the nuclear plants remain on location as abandoned reactors. People often mention exposure to radiation as a primary cause. But these safety systems function adequately only when workers properly install and maintain them. Water needs to cool down the chambers where nuclear fission takes place. Negative effects of Nuclear Energy. The same goes for the storing of any waste product resulting from the nuclear fission process; extra safety measures are meant to prevent uranium from emitting harmful levels of radiation. Even if you do get permission to build a plant that uses nuclear energy, you stumble upon another disadvantage: the massive investment required to set up a functional nuclear power station. Scientists create a nuclear reactor designs with several safety systems in mind that will contain the radiation emitted in the fission process. This by itself makes it one of the most important factors when it comes to selecting it as an energy source. 23 Aug The price of pursuing nuclear energy coincides with many serious safety and security risks, such as its potential to produce catastrophic accidents and ability to have profound human, and environmental consequences. A lot of people believe that nuclear energy only comes with minimal disadvantages, easily outnumbered by the great numbers of advantages. The researcher finds the topic about nuclear interesting because it is one of the issues that our country is facing. Nuclear fission is produced when an atomic atom is split. Once we extract it all, nuclear plants will be rendered useless. Energy is an integral part of our modern-day lives, but do you ever stop to think about the consequences of our constant energy use? Not only does the radiation produced in the creation of nuclear energy cause cancer, but it is known to carry a number of adverse side effects which are detrimental to a person’s health. The principal kinds of ionizing radiation are: TABLE OF CONTENTS It explains the process in a way everyone can understand, and the cute illustrations help, too. As time passes, nuclear energy is used now in a good way that is by generating electricity used by many of the advance countries all around the world.
