Introduction
This report address the issue of whether or not Japan should shut down their nuclear fleet. Down below you will able to read about why Japan should phase out their nuclear power stations.
What It Is
For water to be able to turn into steam, enough heat needs to be developed. A nuclear power plant is a facility that can produce a large amount of electricity.
A nuclear power plant takes nuclear energy and reforms it into useable power. The reactor in a nuclear power plant generates heat, which is usually used to drive a generator and in turn drives an electric generator
Where It Is Found
Its Efficiency
The nuclear power used within nuclear power plants does not produce harmful gases because it does not burn fuels. It is also said to be cheap because to create energy, only a small amount of fuel is required. More specifically, 2 lbs (1 kg) of uranium actually creates as much energy as 3,000 tons of coal. Large amounts of energy are released when the nucleus, of a material like uranium is split up. Power plants that use coal, gas and oil, need large amounts to create electricity. But, nuclear power plants only need a small amount of fuel to make electricity.
Since the coal, gas and oil supply is slowly decreasing it is becoming more costly, considering the fact that they are not renewable. Even though uranium may not be renewable, there are much smaller amounts that are being used by it compared to coal, gas and oil. Unlike fossil fuels that release harmful gases when we burn them, this causes global warming because the gases will capture heat around the earth. This is not produced by nuclear power plants.

A nuclear power plant could overheat which leads to a meltdown. This occurs when the nuclear reactor becomes so hot after it burns, resulting in it to melt. Because the heat from the equipment after it explodes becomes so extreme that it can burn right through concrete walls. This could allow the deadly radioactive material to make its way out and kill anything that may be nearby.
Workers may also make a mistake while working, which can cause a meltdown breakdown.
Overall, nuclear radiation is very powerful and can affect many people and wildlife, such as causing illness or deaths. Exposure towards the children of people may be born with illnesses of disabilities as well. When it comes to proving the link between radiation and ill health it is not always easy.

...ed the water begins to boil and steam is produced. When the steam is produced is moved up towards the reactor opening, as it moves up the steam passes through turbines that spin creating energy. The turbines begin to move which is what produces the energy. During this process a lot of steam is produced which is why so much power is created.
Radioactive Waste One of the most talked about opposition to nuclear fission is the radioactive waste it produces. Radioactive waste is what is left behind after using a reactor to make electricity. There are two levels of waste, low and high, but both are regulated by the Department of Energy and the Nuclear Regulatory Commission. High level waste is made up of fuel that’s been used directly in the reactor, which is highly radioactive but can still be disposed of. Low-level waste is the contaminated items that have been exposed to radiation.
Energy is undoubtedly one of the most important issues facing the world today. While fossil fuels may produce enough energy at a low cost, they also have severe environmental impacts on the world. Wind energy is a clean source, but is also extremely expensive to maintain. Nuclear energy may be the best energy alternative to coal and oil, with the ability to produce much more energy at relatively low cost, while also being more environmentally sound. Nuclear Power comes from the process of splitting Uranium Atoms (also called fission), which in turn releases copious amounts of energy in the form of heat.
Nuclear energy is produced during the process named nuclear fission or nuclear fusion. The development of nuclear energy started in the 20th century and there is now worldwide recognition for using nuclear energy. Popular countries that operates nuclear power are United States, France, Japan, and Russia, the nuclear energy generates up to 6% of the world’s electricity supplies. Even though the energy is mostly used by many countries, but it may causes side effect to the living things in the environment. (WNA, 2012)
Many believe that nuclear power plants are a hazard to the people that live around them and the environment in which they are built. However, these assumptions are based mostly on the fact that the nuclear reactors and nuclear power plants of today are built to the same standards that the old nuclear plants from many years ago. Nuclear power today is designed to be much safer than outdated nuclear power plants and has a very minimal chance of causing a nuclear catastrophe. Nuclear power plants are a safe and viable option for generating electricity for the foreseeable future. One of the most common misconceptions about nuclear energy is that a nuclear power plant could explode like a nuclear bomb and cause a massive nuclear incident.
Of all the accidents and incidents, only the Chernobyl and Fukushima accidents resulted in radiation doses to the public greater than those resulting from the exposure to natural sources. The Fukushima accident resulted in some radiation exposure of workers at the plant, but not such as to threaten their health, unlike Chernobyl. Other incidents (and one 'accident') have been completely confined to the plant.” (WNA). Each plant had its problems, but the only plant to actually cause damage and the loss of human life was the Ukraine reactor in Chernobyl.
The government fails to mention anything about the dangers of radiation caused by an atomic bomb. This is because the government sees more danger in the heat and blast of an atomic bomb than it does the radiation. The heat can cause a burn similar to a severe sunburn. The blast can cause damage to buildings and anything not properly protected. The radiation has not shown affects yet because when they tested the bomb recently they have not had time to see any longterm
...ts shut down to avoid damage. Nuclear reactors are designed so that earthquakes and other natural disasters will not damage the reactors.
Nuclear energy will always be a source for electricity. It has its pros and its cons but nuclear energy is reliable and it will always be available for developing nations. It takes time for countries to build power plants because it isn’t cheap. Also because of high radiation levels, people will always need to be careful when working around uranium because it can cause cancer. Power plants and nuclear energy will always be in use all over the world.
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.”
The use of nuclear energy has increased in the United States since 1973. Nuclear energy's share of U.S. electricity generation has grown from 4 percent in 1973 to 19 percent in 1998. This is excellent news for the environment. Nuclear energy and hydropower are the cleanest large-scale means of electricity production. Since nuclear power plants do not burn fuel, they emit no combustion byproducts—like carbon dioxide—into the atmosphere (www.nei.org). Nuclear power can come from the fission of Uranium, plutonium or thorium or the fusion of hydrogen into helium. Today uranium (U-235 and U-238) is most commonly used in the production of nuclear energy. The expa...
Radiation is one of the most dangerous and easiest way of having health effects. Radiation was first discovered by Roentgen. Hazards are the first things people need to know in order to understand what it can do to your body. It causes many health effects on everyone out in the world. It harms people in the dentistry and field and even in the medical field. Normal people out the world can also be exposed when coming into one of these offices and getting x-rays of some type.
To begin, nuclear power is produced by nuclear fission, which is the splitting of an atom to start a chain reaction (“11 Facts”). This chain reaction produces massive amounts of heat. Nuclear reactors take advantage of this heat by pumping water into the reactor, which in turn produces steam. The steam then becomes pressurized through a pipeline and exits into a turbine (“How do Nuclear”). The pressurized steam causes the turbine blades to spin, producing power which is linked to a generator for use in the main power lines. When the steam passes the turbine blades, it goes past cooled pipes and condensates (“How do Nuclear”). After the condensation process is finished and the steam reverts back to water, it is pumped into the reactor again, thus completing the process of producing nuclear-based power.
Nuclear power, the use of exothermic nuclear processes to produce an enormous amount of electricity and heat for domestic, medical, military and industrial purposes i.e. “By the end of 2012 2346.3 kilowatt hours (KWh) of electricity was generated by nuclear reactors around the world” (International atomic energy agency Vienna, 2013, p.13). However, with that been said it is evident that the process of generating electricity from a nuclear reactor has numerous health and environmental safety issues.
As one of the greatest alternatives to fossil fuels, an important advantage of nuclear energy is the significantly lower emission rate of CO2 in comparison to plants which use coal and natural gas.2 Nuclear power is not reliant on fossil fuels and therefore producing energy by this method reduces pollution and the contribution to climate change. However, whilst the actual process of generating energy releases few emissions, uranium must be mined and purified and in the past this has not always been an environmentally clean process.2 Ultimately, uranium will one day run out, but nuclear reactors are versatile and may also run on Thorium. Despite being finite, this would allow nuclear power stations to function for a longer period of time.
