Part I Nuclear Fission vs. Nuclear Fusion. Both fission and fusion use atoms, specifically the neutron and proton, to generate energy. The protons and neutrons make up the nucleus of an atom, therefore making up the mass, which is converted into energy, but fission and fusion are two different ways of harnessing that energy. In a fission reaction, the nucleus of an atom is split. Neutrons are released, forming nuclear energy, and the remaining nuclei are lighter.1 Think of fission a little bit like opening a nutshell, for example, a pistachio. As you put pressure and force into breaking the shell, it breaks in two and pieces may fly off. Similarly, when the atoms are forced apart, they break in two and neutrons fly away and energy is released. In a fusion, two atoms’ nuclei join to create a much heavier nucleus.1 The two atoms collide and together make a new atom while releasing neutrons in the form of energy. Imagine this as two cars in a head-on collision. When they collide, they stick together (not forming a new atom like in nuclear fusion, but let’s pretend,) and when they crash, some of the bumper flies off. The atoms collide and neutrons, like the bumper, fly off in the form of energy. 1: UC Davis, ChemWiki: The Dynamic Chemistry E-Textbook, Fission and Fusion.

And the Cold War led to this nation’s depression and it hurt not only our nation, but also the world. This project has opened my eyes to the dangers and uses of nuclear energy and has given me insights on policies and terms associated with nuclear energy in general. Nuclear energy is beautiful and powerful, but it is also destructive and dangerous, and in the wrong hands, deadly. Our world needs nuclear energy, but may be destroyed by nuclear weapons. There is a give and a take, a light and a darkness, and nuclear energy is no exception. What we need is caution, knowledge about nuclear energy, and a plan for the future. This project has given me those things, now I must go out and make the world a better place. 1: http://www.reuters.com/article/2014/05/20/us-northkorea-nuclear-idUSBREA4J06020140520
When the released neutrons attach to other isotopes of Uranium 235, this can result in a chain reaction of fission. For every generation of fission, the amount of fission is doubled, and this results in an extreme outburst of energy. The amount of energy released by this process is related to Einstein’s famous equation “E=mc2” (Wolf). Einstein's equation "E=mc2" has two sides, which are constructive and destructive. The constructive side is when energy is converted into mass, and the destructive side is when a small amount of mass is converted into energy.
All these effects were the cause of the discovery of nuclear fission and its properties. Nuclear Fusion Nuclear fusion is the process used by the sun and the stars in our solar system to produce their energy. Fusion involves smashing hydrogen atoms together at high velocities to form helium, and the matter is made into energy.
Nuclear energy must be a consideration for the future with the rapidly depleting supply of fossil fuels. This type of energy can be created through nuclear fission and nuclear fusion. Nuclear fission is the splitting of a heavy atom into two or more parts, releasing huge amounts of energy. The release of energy can be controlled and captured for generating electricity. Nuclear fusion involves bombarding hydrogen atoms together to form helium. In the long run, nuclear fusion has greater potential than fission.
(Action): If we don’t do our part to stop the expansion of nuclear power plants, the future of our planet will be bleaker. Every year, thousands of more pounds of nuclear waste will be buried underground and the damage to our environment increases. There are more efficient energy sources other than nuclear power and we must do our part today to prevent a catastrophic future for our children. The dangers that nuclear power plants pose for the United States are very real. There are many alternative renewable sources of energy available to us such as wind and solar power, which provide a much safer and efficient alternative to nuclear power. You alone have the power to speak up and act against the expansion of this dangerous energy. The future of our environment’s safety and our nation’s energy supply lies in your hands.
...nce World War II to the present day, the technology of nuclear power has increased significantly in terms of energy output and safety. The energy efficiency of nuclear power is far superior to its counterpart fossil fuel and renewable energy. Compared to fossil fuels, tiny amounts of fuel used by nuclear reactors is equivalent to a large sum of coal. This is a no brainer. Why mine a ton of coal when a little uranium can be used to gain the same amount of energy? Not only is it efficient, it’s safe to use. Used fuel is packed away in storage safely, so there isn’t any chance of radiation leaking out. In the present day, nuclear power incidents haven’t been occurring lately. Advancements in technology and equipment used have made nuclear energy a very reliable and safe source of energy. With today’s energy needs, nuclear power has the ability to keep up in the race.
Since its beginning, the Manhattan Project has become synonymous with images and ideas of death, devastation and war. What few people consider though, is that without the United States initial concern in creating weapons of mass destruction, there would be larger changes in society than simply having less bombs. Nuclear energy production was hardly given a thought before scientists saw the awe-inspiring power of nuclear fission. The work going towards the Manhattan Project did more than create destructive weapons of death, it changed the face of the earth, and in more than one way.
Topic Sentence: today nuclear weapons are more dangerous than it ever was. Why? Because of the rapid increase of global terrorist threats and countries that are building nuclear weapons without anybody knowing. Like Pakistan, they have at least fifty known nuclear weapons and are threatened by al Qaeda terrorists that they promise. If they ever get their hands on any of the nuclear weapons, they will not think twice about using it. Nuclear weapons are really a weapon of mass destruction. It can be poisonous to air, soil, water, and it can go across national boundaries. The only known countries that have them are China, France, India, Pakistan, Russia, United States, and United Kingdom. If these nuclear weapons are tested, it can lead to a global
“Face it. Nukes are the most climate-friendly industrial-scale form of energy” (Power, Reiss, Pearlstein, 655). This statement is what I’m trying to promote through my argument. It also ties Inconvenient Truths: 10 Green Heresies by Matt Powers, Spencer Reiss, and Jonanna Pearlstein and Nuclear Power is Best Energy Source: Potchef Stroom together by bring out the main point all authors are trying to get across. Global warming has been a big concern for years now and one of the biggest causes for it, is the burning of fossil fuels to get energy. People that live in the United States of America use a huge amount of energy in their daily lives and that amount continues to grow with our population growing with it. My purpose of this piece is to persuade people to switch to nuclear power for a cleaner energy source because it’s the cleanest energy source.
The Cold War was a political standoff between the Soviet Union and the United States that again created a new worldwide nuclear threat. The destructive potential of nuclear weapons has created a global sweep of fear as to what might happen if these terrible forces were unleashed again. The technology involved in building the first atomic bombs has grown into the creation of nuclear weapons that are potentially 40 times more powerful than the original bombs used. However, a military change in strategy has come to promote nuclear disarmament and prevent the usage of nuclear weapons. The technology of building the atomic bomb has spurred some useful innovations that can be applied through the use of nuclear power.
The discovery of fission occurred during a time of great turmoil. Two German physicists then later verified by two Jewish refugee physicists discovered it. Italian Physicists Enrico Fermi later discovered the unique quality of fission that was induced by neutrons but also produced neutrons. This created the idea of a self-sustaining chain reaction, and the large amount of energy found within a nucleus was now accessible at a large scale (Nuclear weapons section, para 1).
From the creation of nuclear weapons at the start of the Cold War to today, the world has experienced struggles fueled by the want of nuclear power. The bombings of Hiroshima and Nagasaki, the Cuban Missile Crisis, and Iran’s nuclear weapon program are some of the most important conflicts over nuclear weapons. Thanks to the use of nuclear weapons in 1945 to end World War II, the world has come extremely close to a nuclear war, and more countries have began developing nuclear power. Unmistakably, many conflicts since the start of the Cold War have been caused by nuclear weapons, and there are many more to come.

In 1945, when the Americans bombed Hiroshima, Japan, approximately 140,000 men and women were instantly killed by the effects of American nuclear defense. With such extreme brutality and force how many people must die for one to finally realize the strengths of nuclear bombs and what damage they can cause. Nuclear weapons should be outlawed because they kill thousands of innocent humans at a time, destroy the environment, and inviolate human’s right to moral and personal freedoms.
Nuclear fusion occurs when two atomic nuclei collide with enough energy to bind together to form one nucleus. Nuclear fusion occurs in the core of our sun, and is the source of its tremendous heat. In the sun hydrogen nuclei, single protons, fuse together and form a new nucleus. In the conversion, a small amount of mass is converted into energy. It is this energy that heats the sun.
Nuclear energy is generated by a process called fission. Fission occurs within the reactor of a nuclear power plant when a neutron is fired at an atom of uranium causing it to split and release subsequent neutrons.1 These are able to crash into other uranium atoms causing a chain reaction and releasing a great deal of heat energy.
