Downside of Nuclear Energy:
Energy production has been a major issue that has attracted huge concerns in the recent past because of the negative environmental impacts associated with generating energy through burning of fossil fuels. A growing interest in nuclear power has significantly increases during this period as it is considered as a real solution to energy security and means of dealing with climate change. Actually, there have been concerns on whether nuclear power is the solution or answer to a warming planet or it is dangerous and expensive to meet the future energy needs of the modern society. While some people have argued in support of the use of nuclear energy as a solution to these problems, others have opposed such attempts. These varying opinions have been based on arguments and counter-arguments that demonstrate the advantages and disadvantages of nuclear energy.
Increased Attention on Nuclear Power:
As previously mentioned, nuclear power or energy has received huge attention and focus in the recent past because of the environmental effects associated with energy production from burning of fossil fuels, particularly global warming or climate change. In addition to other alternatives, nuclear power is currently being considered as a real solution to the energy security and a major way of addressing the problem of global climate change. There has been an ever-growing interest in nuclear energy because of increasing search for green alternatives to fossil fuels like natural gas and coal, which has received support from some environmentalists because of the dangers and threats of global warming.
The Nuclear Fuel Cycle:
According to Adamson, "the process that produces energy in a nuclear reactor is a slowed-down version of what happens in an atomic bomb (p.23)." The development of atomic energy for bombs involves a very rapid chain of reaction that occurs in a radioactive material, which releases huge amounts of energy in a fraction of a second i.e. producing an explosion. In a nuclear power plant, there is a much smaller portion of the radioactive fuel that is involved in a chain reaction at a specific moment. Therefore, rather than having a single explosion during this process, there is an ongoing procedure of small releases of energy. The generated energy in turn heats a gas or water in the core of the nuclear reactor. Once these processes are completed, electricity is generated in a similar manner like oil or coal burning plant through the use of steam to drive a turbine. This implies that nuclear power is basically a complicated procedure to boil water to produce energy.
Generally, the principle of energy production in a nuclear reactor is similar to that of oil and coal burning plants. In this case, the fuel is consumed, generating energy which heats a gas or liquid that drives an electricity-generating turbine. Heat is generated in a nuclear reactor since the fuel i.e. uranium is unstable and produces particles and bursts of energy as it break downs in order to heat the gas or liquid between the fuel. In order to generate fuel that is adequately unstable, it is always important to purify the initial uranium ore. Secondly, plutonium, which occurs as a by-product of nuclear fission or atomic breakdown in a nuclear reactor, must be separated from the waste products through reprocessing. Third, poisonous radioactive wastes must be eliminated since it is impossible to separate the issue of waste disposal and reprocessing from nuclear power. Actually, the two major issues facing the nuclear industry are waste disposal and reprocessing because of their role in nuclear energy production.
Arguments in Support of Nuclear Energy:
There are various arguments that have been raised in support of nuclear energy production as an alternative in an energy-limited world. The proponents of nuclear power support their arguments on the basis that the economics are not only logical but also sensible and that the public has a distorted perspective of safety risks. According to Totty, "The argument for nuclear power can be stated pretty simple: We have no choice." (par, 4). An ambitious expansion of nuclear power is regarded as the solution for addressing the threat of global warming and satisfying the ever-growing need for electricity or energy security.
The first reason is the argument that nuclear energy has minimal environmental effects since nuclear power plants produce virtually no carbon dioxide and no mercury or sulfur. Even in consideration of full life-cycle emissions, discharges of carbon-dioxide from nuclear power generation is akin to the full life-cycle emissions of hydropower and wind while less than solar power. Secondly, nuclear power is the only alternative that fits the bill on the basis of displacing fossil fuel and meeting the demands for electricity or energy on a 24-hour basis. Unlike the other non-renewable energy sources, nuclear power plants have the capacity to generate more electricity and meet the demands to energy security with less environmental effects.
The Case against Nuclear Power:
Even though arguments in support of nuclear power are quite logical, there is a stronger case against nuclear power that is based on two major factors i.e. economics and safety. Furthermore, the two major thorny issues in nuclear power industry also demonstrate the seeming inability to develop and establish a viable long-term nuclear industry. When considering nuclear power as an alternative to existing problems brought by current methods of energy production, it is important to be realistic about the limits of this alternative as well as others. Actually, a critical evaluation of arguments in support of nuclear energy fosters the case against this form of energy production.
When the actual costs of nuclear power are compared to the real benefits of using renewable energy technologies, it is increasingly obvious that renewable energy sources have significant positive impacts and numerous benefits. Investments in nuclear energy seem illogical and inappropriate since the world is currently in search of energy security and solutions to global climate change. In reality, the actual solutions to the issue of energy security and climate change are currently available and nuclear power is not among them because it is the most dangerous and expensive means of generating electricity ("The Case against Nuclear Power," p.1). The deployment of renewable energy requires minimal to no fuel inputs so as to exploit free and clean sources of energy such as sun and wind that are widely available and accessible throughout the world.
The case against nuclear energy is supported by the impossibility in separating the issues of waste disposal and reprocessing from nuclear power unlike other energy sources. The ability to generate nuclear energy is dependent on the ability to carry out effective purification and reprocessing at every stage of the process. Waste disposal and reprocessing are very crucial in nuclear energy since every step in this process is dependent on the next and the cyclic re-use of fuels (Adamson, p.25). Since every stage is in the full life-cycle of nuclear energy is characterized with major problems with no socially-acceptable solution, the development and establishment of nuclear power is impossible.
Apart from these factors, the case against nuclear power is supported by other major reasons including & #8230;
Some people have argued that nuclear power plant is more cost-efficient with regards to the cost of electricity per kilowatt. As a result, these people argue that nuclear energy is cheap as compared to the existing energy sources and renewable sources of energy. This source of energy seems to be economically uncompetitive because mainly because of the cost of cheaper fossil fuels do not reflect high costs associated with emissions of greenhouse gases into the Earth's atmosphere. For instance, it is estimated that a carbon price of between $25 and $50 a ton leads to the economical competitiveness of nuclear power with coal. Therefore, when the costs of the existing sources of power are combined, nuclear energy seems to be a huge bargain.
However, researchers refute this claim by arguing that the costs of obtaining, maintaining, and disposing nuclear power plants are relatively high. Actually, no one knows the cost of a new reactor until one is developed while estimates for new construction continue to escalate (Totty par, 42). It is estimated that constructing a new nuclear power plant could cost more $6,000 a kilowatt of generating capacity as compared to six years ago when it was estimated to be around $4,000 for the same capacity. The increase in cost estimates is also attributed to the small number of vendors who are able to supply crucial reactor components and shortage of construction and engineering skills. In addition, if a nuclear power plant was really cost efficient as claimed, the invisible hand of market will push the trend. Nonetheless, nuclear energy only contributes to less than 10% of electricity across the globe. The issue of the costs of developing and maintaining a nuclear power plant implies that only few if any nuclear energy plant will be built in the next couple of years.
Since the costs of developing and maintaining a nuclear power plant are…[continue]

Nuclear Energy: Risks vs. Reward Every source of energy has its own drawbacks. This is more so the case taking into consideration the recent energy source related accidents including but not limited to coal-mining mishaps, the nuclear crisis in Japan, the B.P. oil spill, etc. In this text, I will amongst other things concern myself with nuclear power and the consequences associated with the development of the same. As I have already
Nuclear Energy Nuclear Power: A Short Commentary on the Safety of Nuclear Energy The question of safety in the utilization of nuclear energy has been discussed in the world debate forum on nuclear issues since the inception of nuclear technology in the 1940's. Many experts believe that nuclear energy can be utilized safely, and many advocate for the continued utilization of nuclear energy. Yet there are some among illustrious scientists who believe that
Another important argument against nuclear energy is that it leaves behind radioactive waste, as evidenced above as well. Furthermore, if this waste is not properly disposed of, it can cause irrevocable damage. According to the Discovery Curiosity project, "Nuclear waste must be sealed underground in protected chambers. [A] former salt mine in Remlingen, Germany, held nuclear waste for decades before structural concerns forced the government to relocate the deadly substances."

The developing nature of the economy today has determined an increase in the energy consumption worldwide, especially given the rising of a new economic world power, China that has at this point surpassed
This can merely be helpful on local level but not at all on the global level. Radioactive materials in low quantities are present in fossil fuels, chiefly in coal and using them in heavy amounts can have more hazardous effects on the environment causing radioactive contamination globally. This is a much more pressing concern when compared to the radioactive contamination within a nuclear power station as the noxious waste in
This debate is stated to have been lost by Bethe and he finally agreed to work as a consultant since he had failed to dissuade the building of a thermonuclear bomb and provided contributions to the effort focused toward design of the bomb. In contrast the physicist Teller had "been obsessed with the need to develop the hydrogen bomb ever since Enrico Fermi, suggested the possibility to him in
But the threshold nuclear-weapons states will not give up their nuclear option without seeing proof of a timetabled move towards a nuclear-free world. The road towards the nuclear-free destination includes still deeper reductions in the nuclear arsenals of the five nuclear-weapons states; further constraints on the deployment of their nuclear weapons on the territories of other states, for example by means of regional nuclear-weapon-free zones; the entry into force
