Nuclear fission is the process where the nucleus of an atom splits into two nuclei, by colliding with another particle or it can occur naturally, and releasing a great amount of energy. This energy can be harnessed and be put to good use, such as to generate electricity in a nuclear reactor. This energy can also harm people it can be used to create a nuclear bomb and can cause a huge catastrophe. Another problem with nuclear fission is the waste that it produces. These are the pros and cons of nuclear energy.
So we can harness the energy that is produced through the process of fission and generate electricity. All this is done in nuclear reactors. A core of Uranium is at the center of the reactor. Uranium, Uranium-235 is the preferred isotope, is used because it under goes fission naturally and at a slow rate. The energy that is emitted from the Uranium is then used to heat up water. The water then turns into steam and the steam pushes a turbine that spins a generator to produce electricity. That is the basics on how a nuclear reactor works. This method is better than traditional coal power plants because it emits minimal levels of carbon dioxide into the air. This process is also more reliable than other forms of alternative energy like solar panels or wind turbines. Because we can’t control the weather it won’t all always be sunny for a solar panel and it won’t always be windy for wind turbines. Nuclear reactors can lat from 40 to 60 years.
This sounds too good to be true and it is, because many things can go wrong and the result would be an environmental catastrophe. The most famous examples of a nuclear reactor meltdown are Chernobyl and in Japan. In 2011 a 9.0 earthquake hit off the coast of Japan and triggered a huge tsu...

We are exposed to small and non-lethal doses of radiation everyday. The type of radiation that is very lethal to humans and all other life is gamma radiation. This type of radiation, if you are exposed to it, alters the molecular structure of your DNA and can lead to mutations in your offspring and can lead to diseases like cancer. Alpha and Beta particles are usually deflected by your skin and they aren’t as harmful. Alpha, Beta and Gamma radiation are types of ionizing radiation which means they can remove the electrons in the atoms of your cells, which can cause cells to mutate. Radiation is can be useful in our everyday lives. It is used in X-ray machines to look at the bones inside your body and a lead vest is put around you to protect you from the radiation so you are not fully exposed to it.
Radiation exposure can affect children as well an children have the risk of being the most harmfully effected by radiation because their body absorbs substances differently also their bodies can or are more likely to get certain kinds of cancers from too much exposure, “they are also closer to the ground, where radioactive fallouts settle.”
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.
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.
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.
As nuclear fission became a reality during World War II, the world became entrenched in a race to build and detonate the first atomic weapon. This led to the development of the Manhattan Project, in which the United States constructed the first atomic weapon. On August 6th and 9th of 1945, atomic bombs were detonated over both Hiroshima and Nagasaki Japan respectively. Although the dropping of atomic bombs had led to the end of World War II, it was unethical for the United States to detonate them over the citizens of Japan due to the adverse effects it had brought upon the international community.
There are many sources of energy today, and the best source of it is constantly being sought after, one source stands out above the rest. Nuclear energy is simple in theory, yet it may be one of the most controversial sources of power. Nuclear energy works using reactors built to split the atoms (nuclear fission) of the fuel to produce heat. This heat evaporates the cooling agent (usually water) into steam which turns turbines to create electricity. Nuclear energy should be allowed, because it produces an abundance of electricity, as well as being a clean source of energy with no harmful emissions. Nuclear energy is the future of clean, environmentally friendly energy.
When it comes to nuclear war, most people will have mixed feelings on it. Nuclear war is a difficult area to touch on. Whether or not someone sees it as ethically right or wrong, all depends on the person and their moral values. The reason I chose this was because I don’t think it is necessarily right to engage in nuclear warfare even if it is the only means to end war. Just-war theory, utilitarianism, and Virtue ethics all help show a different perspective on nuclear warfare. There are many solutions to it, however. Some solutions are getting other nations to place embargos on the country and forcing peace talks without resorting to military action. Significantly, it is important that nuclear war is addressed in the world so that nations
Fission is a nuclear process that takes place in the nucleus of an atom. It is a process whereby a nucleus of a heavy, neutron enriched atom, usually Uranium-235 (U-235), splits into two or more smaller nuclei. This process releases substantial amounts of energy as a by-product.
One of the biggest and most prevalent problems is the need for clean, renewable, sustainable energy. On the forefront of these problems comes the following solutions: nuclear energy, hydro-electric energy, and photovoltaic energy. With the need for energy in today’s current world, exploring different ways of producing power is necessary. The differences and similarities between nuclear energy and alternative energy are important to look over and examine in depth, so that it is plain to see the positive and negative effects of energy production. To begin, nuclear power is produced by nuclear fission, which is the splitting of an atom to start a chain reaction (“11 Facts”).
Nuclear submarines are fueled with nuclear energy as well as carrying nuclear torpedos on board. They are more cost efficient as well, compared to air independent propulsion (AIP) submarine in the long run. As stated by the Military and General Security, nuclear submarines cost $2 billion to maintain for life. AIP subs have a total endurance of forty-five to ninety days compared to the ninety to a hundred days by a nuclear weapon sub. The nuclear weapon sub could endure longer limited by the factor of food storage for the crew. The crew is not harmed by the nuclear factors on the nuclear subs.
I think that right now, fission is the only way that we can get more
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.
Okay let's start out with the basics of how a nuclear power works. You have a nuclear reactor, tubes that carry superheated radioactive
The energy in ionizing radiation can cause chemical changes in the the cells that can lead to damaging them. Most of the cells can either permanently or temporarily become abnormal or they can just die. Radiation can cause cancer by damaging the DNA in the body. The damage of the cells can also depend on how long the organs are exposed (environmental protection agency, 2017, unknown). If someone has many exposures at one time that radiation in the body keeps adding on. As well as if its only a little bit of exposure in on day and years later you get exposed again it keeps adding on the radiation will never leave the body. Having radiation in your body doesn’t affect you right away but as you get older it starts to show and you feel it. Chronic exposure is when someone is exposed many time for long periods. When this happens the type of effects it will carry is having harmful generic change, cancer, tumors, and even cataracts. Partial health effects can also depend on if it was internal or external exposure. Internal exposure is when either by drinking, breathing, eating and even an injection cause radiation to get inside your body. External exposure is when taking an x-ray out of your body and letting it go through letting all the energy go as it goes in (environmental protection agency, 2017, unknown). In the dental world radiation gets into the patients when we take x-rays on there teeth. In order to avoid to much radiation on them we put a lead apron on them and make sure to cover their thyroid which is the most common way of getting cancer when taking an x-ray. When we take the x-ray we stand behind a wall at least 6 feet away to avoid ourself from getting
