Radioactive Waste One of the most talked about opposition toward nuclear fission is the radioactive waste it produces. A 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 that is highly radioactive but can still be disposed. Low level waste is the contaminated items that have been exposed to radiation. The nuclear wastes are then stored in a safe and secure location with different types of methods such as wet storage, dry storage, and away from reactor storage. Wet storage is the main method of disposing the waste because it is the
Any country with a nuclear program has the prospective to make nuclear weapons. The fuel of a nuclear reactor at its core is uranium. Low enriched uranium is used in energy production while the highly enriched version is used to make weapons and is called weapons grade uranium. The atom bomb that landed in Hiroshima used 60kg of weapons grade uranium and since the advancements of warfare it now only requires 20-25kg to make a nuclear weapon. Plutonium which is a byproduct of the fission process can also be used for manufacturing weapons and only requires 2-10kg to develop weapons. The atom bomb that landed in Nagasaki contained plutonium fuel. Depleted uranium, which is the left over from the enrichment process, is used to make military grade armor piercing bullets. These DU penetrators have been used in wars throughout history the most recent being the Gulf wars. This is a disadvantage because the depleted uranium is toxic and has been scientifically proven cause birth defects, cancer, and death where it was used. All these effects were the cause of discovering nuclear fission and its
The development of atomic bomb boosted the level of understanding in terms of physics and chemistry of that particular time period. Physicists started to realize that stable nuclei can be converted to unstable nuclei. Through such process, they discovered that heavy nuclei can undergo nuclear fission. While testing, they added a neutron to an isotope of Uranium 235. This resulted Uranium 235 to become unstable and break down into Barium and Krypton, releasing two to three more neutrons. The breakdown of Uranium 235 is called “fission”. 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 resulted in an extreme outburst of energy. The amount of energy released by this process is related to Einstein’s famous equation “E=mc^2” (Wolf).
Before we can analyze the ethical use of DU ammunition, it is important to first establish the technology behind DU and DU weapons. Uranium is one of the heaviest elements found in nature and is emits alpha, beta, and gamma particles. It is 1.7 times denser than lead.12 The half-life of U238 (DU is 99% U238) is 4.5 billion years!13 Uranium byproducts(such as Thorium (Th232)) have even longer half-lives, making uranium an element that gets more radioactive during its own decay process.5 Natural uranium is 99.274% U238, 0.720% U235, and 0.0055% U234.14a Uranium is enriched when its contents of U235 reaches 3.2-3.6% (since U235 is fissible). Weapon-grade uranium is +90% U235.14a What is depleted uranium? We start out with natural uranium and extract enriched uranium for nuclear fuel and weaponry. The leftover from the extraction process is something very similar to natural uranium, known as “depleted uranium”. The only difference is that DU has 0.202% of U235 and 0.0008% of U234.14a How much DU do we currently have? As of June 1998, we have around 57,800 huge steel cylinders of DU or 496,000 metric tons. 14b Storage of DU is very complicated and problematic since corrosion of DU storage cylinders often occurs over relatively short periods of time.15
The article “Nuclear Waste” is an interesting perspective from Richard Muller. Muller is a very credited author and he speaks his mind about the situation where people are trying to figure out how to deal with nuclear waste around the U.S. There are many proposed ideas but Muller has a very simple and straight forward idea that he believes is the ideal decision. The essay he wrote can be interpreted in different ways but his motive for writing is very clear. Muller’s background is quite impressive because he is highly credited. When reading Muller’s essay, you notice points that supports his argument and truth about the situation around nuclear power.
mining of uranium which is a resource used to creating nuclear weapons also causes nuclear
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.
This is done to make sure the risk of meltdown is minimized. The nuclear waste is so toxic that every precaution is taken to make sure of is disposed of safely to keep it from poisoning the environment. In an article titled 11 Facts about Nuclear Energy we find out that, “Every 18 to 24 months a power plant must shut down to remove its spent uranium fuel.” Nuclear Power plants can have a meltdown that releases extremely toxic waste into the environment. The reason some people are opposed to nuclear power plants, some estimates say that there is a 50% chance of a meltdown in a U.S. reactor in the next 20 years (“55 Interesting Facts about. Nuclear Energy”). These meltdowns can be small or large, both of them take a lot of money and time. The Three Mile Island disaster alone took 975 million dollars and 14 years to clean up (“55 Interesting Facts about. Nuclear
In addition to the potential dangers of accidents in generating stations, nuclear waste is a continuing problem that is growing exponentially. Nuclear waste can remain radioactive for about 600 years and disposing these wastes or storing them is an immense problem. Everyone wants the energy generated by power plants, but no one wants to take responsibility for the waste. Thus far, it is stored deep in the earth, but these storage areas are potentially dangerous and will eventually run out. Some have suggested sending the waste into space, but no one is sure of the repercussions.
Nuclear power is a relatively new method of supplying the ever growing population with the electricity that is required. Although the majority of people are unsure of how generation occurs, nuclear power provides roughly 17% of the world’s power. (Rich, Alex K...) This makes nuclear power a deciding factor in how the race progresses in technology and energy fabrication as it is able to produce mass amounts of electricity in short periods of time. The limit potential for nuclear power is unclear in not only energy but also weaponry and some medical uses. The fact that uranium and the radioactivity that comes with it are used in facilities and other inventions often lead people to distrust the inventions which, while not entirely un-called for, hinders progress and leads to fables and tales around nuclear energy, its creation, and the nuclear power plants that are springing up around the world. This causes nuclear facilities to slow in their development which only makes things worse because as things progress the facilities will only get increasingly safe as long as they are handled professionally. (Rich, Alex K…) Some of the slanderous fables around nuclear power include things like claiming that nuclear facilities cannot operate during droughts and water shortages. (Kharecha, Pushker…) While nuclear power is accompanied by several risks, it can also be the solution for various global strains and difficulties.
Nuclear Arms, as opposed to conventional arms, generate their destructive force from nuclear reactions. The issues that are related to the use of nuclear weapons is also far different than the issues generated by conventional bombs. The long term
There are many different types of radioactive waste, but the two major types are “low-level waste” and “high-level waste” (“Radioactive Waste Management”). There are a few different ways that we can store these wastes depending on what level they are. The low-level waste mainly comes from medical facilities or some type of industry (“Radioactive Waste Management”). In order to dispose of the low level wastes, they are usually placed in a radioactive waste material storage bin and stored at the hospital or site that they were produced at (“Radioactive Waste Production”). There are only a few sites that will actually take the low level wastes and store them in the United States. However, they will only take specific types of this low level waste and will only allow the wastes from certain permitted states (“Radioactive Waste Production”). The low-level wastes can also be disposed of by being placed ...
Since the dawn of civilization, all living (and some non-living) things have needed energy. When humans discovered fire, the first form of harnessed energy, it made it easier to stay warm, prepare food, make weapons, etc. Since then, humankind has been inventing new ways to harness energy and use it to our advantage. Now-a-days, people in most nations depend extremely heavily on fossil fuels – to work, travel, regulate temperature of homes, produce food, clothing, and furniture, as well as other power industries. Not only are these fossil fuels dominating our society and creating economic vulnerability, but they also produce waste that causes a number of social and environmental concerns. The waste from these fuels leads to acid rain, smog, and climate change. It also releases sulfur dioxide as well as other air pollutants that are very harmful to the human respiratory system (Morris, 1999, p. ix). There are other alternative sustainable energy sources including solar, hydroelectric, wind, and biomass. However, the main source aside from fossil fuel is nuclear energy from controlled nuclear reactions (where nuclei of radioisotopes become stable or nonradioactive by undergoing changes) in a nuclear power plant. Nuclear power produces enormous amounts of energy to serve a community. Unfortunately, nuclear energy has its own set of problems – a big one being its waste. The spent fuel from nuclear plants is radioactive. This means that it emits radiation, or penetrating rays and particles emitted by a radioactive source. Ionizing radiation is known to cause cancer, and therefore makes anyone who lives near spent nuclear waste facilities vulnerable to this incurable disease. The disposal of nuclear waste is a global issue...
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.
Our earth is the only one we have so shouldn't we take care of it? Well, we have not been. Almost everything we do to produces energy has some effect on our earth. Usually, it's not good. For the past 10 years we have been producing some of the most incredible technology imaginable, but it has been at a cost to to something much greater. If we continue to use natural gas and oil to fuel our power plants to produce energy we will kill our earth.we as antaion like to believe that we are diverse when it comes to how we produce electricity, but we aren't. A far high majority of it is from natural gas/fossil fuels/crude oil. One may see the occasional wind farm or solar panel array around but that has virtually no effect on the overall picture.
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.
