The nuclear power debate is a long-running controversy [2] [3] [4] [5] [6] [7] [8] about the risks and benefits of using nuclear reactors to generate electricity for civilian purposes. The debate about nuclear power peaked during the s and s, as more and more reactors were built and came online, essays on nuclear power, and "reached an intensity unprecedented in the history of technology controversies" in some countries.

In the last decade, however, with growing public awareness about climate change and the critical role that carbon dioxide and methane emissions plays in causing the heating of the earth's atmosphere, there has been a resurgence in the intensity of the nuclear power debate.

Nuclear power advocates and those most essays on nuclear power about climate change point to nuclear power's essays on nuclear power, emission-free, high-density energy, alongside a generation of young physicists and engineers working to bring a new generation of nuclear technology into existence to replace fossil fuels.

On the other hand, skeptics point to nuclear accidents such as the death of Louis Slotinthe Windscale firethe Three Mile Island accidentthe Chernobyl disasterand the Fukushima Daiichi nuclear disastercombined with escalating acts of global terrorism, to argue against continuing use of the technology.

The debate continues today between those who fear the power of nuclear and those who fear what will happen to essays on nuclear power earth if humanity doesn't use nuclear power. At the ground-breaking for what would become the world's largest nuclear power plant, President John F. Kennedy declared that nuclear power was a "step on the long road to peace," and that by using "science and technology to achieve significant breakthroughs" that we could "conserve the resources" to leave the world in better shape.

Yet he also acknowledged that the Atomic Age was a "dreadful age" and "when we broke the atom apart, we changed the history of the world. Proponents of nuclear energy argue that nuclear power is a clean and sustainable energy source which provides huge amounts of uninterrupted energy without polluting the atmosphere or emitting the carbon emissions that cause global warming.

Use of nuclear power provides plentiful, well-paying jobs, energy securityreduces a dependence on imported fuels and exposure essays on nuclear power price risks associated with resource speculation and Middle East politics. Modern society demands always-on energy to power communications, computer networks, transportation, essays on nuclear power, industry and residences at all times of day and night.

In the absence of nuclear power, essays on nuclear power, utilities need to burn fossil fuels to keep the energy grid reliable, even with access to solar and wind energy, because those sources are intermittent, essays on nuclear power.

Proponents also believe that nuclear power is the only viable course for a country to achieve energy independence while also meeting their "ambitious" Nationally Determined Contributions NDCs to reduce carbon emissions in accordance with the Paris Agreement signed by nations. They emphasize that the risks of storing waste are small and existing stockpiles can be reduced by using this waste to produce fuels for the latest technology in newer reactors.

The operational safety record of nuclear is excellent when compared to the other major kinds of power plants [14] and by preventing pollution, actually saves lives every year. Opponents say that nuclear power poses numerous threats to people and the environment and point to essays on nuclear power in the literature that question if it will ever be a sustainable energy source, essays on nuclear power. These threats include health risks, accidents and environmental damage from uranium miningprocessing and transport.

Along with the fears associated with nuclear weapons proliferationnuclear power opponents fear sabotage by terrorists of nuclear plants, diversion and misuse of radioactive fuels or fuel waste, as well as naturally-occurring leakage from the unsolved and imperfect long-term storage process of radioactive nuclear waste. The World Nuclear Association has reported that nuclear electricity generation in was at its lowest level since The WNA has said that "nuclear power generation suffered its biggest ever one-year fall through as the bulk of the Japanese fleet remained offline for a full calendar year".

The figures illustrate the effects of a full year of 48 Japanese power reactors producing no power during the year. The permanent closure of eight reactor units in Germany was also a factor.

Problems at Crystal RiverFort Calhoun and the two San Onofre units in the USA meant they produced no power for the full essays on nuclear power, while in Belgium Doel 3 and Tihange 2 were out of action for six months.

Brazil, China, Germany, India, Japan, Mexico, the Netherlands, Spain and the U. now all generate more electricity from non-hydro renewable energy than from nuclear sources. For some countries, nuclear power affords energy independence.

Nuclear power has been relatively unaffected by embargoesand uranium is mined in countries willing to export, including Australia and Canada, essays on nuclear power.

One assessment from the IAEA showed that enough high-grade ore exists to supply the needs of the current reactor fleet for 40—50 years, essays on nuclear power. Escalation of uranium fuel costs decreased the viability of nuclear projects. The International Atomic Energy Agency and the Nuclear Energy Agency of the OECDin their latest review of world uranium resources and demand, Uranium Resources, Production, and Demandconcluded that uranium resources would support "significant growth in nuclear capacity," and that: "Identified resources are sufficient for over years, considering uranium requirements of 61 tU.

According to a Stanford study, fast breeder reactors have the potential to provide power for humans on earth for billions of years, making this source sustainable. Inthe worldwide average capacity factor was The 7, hours is roughly representative of how long any given reactor will remain critical in a year, meaning that the scram rates translates into a sudden and unplanned shutdown about 0.

The unplanned capacity loss factor represents amount of power not produced due to unplanned scrams and postponed restarts, essays on nuclear power. According to World Nuclear Association "Sun, wind, tides and waves cannot be controlled to provide directly either continuous base-load power, essays on nuclear power, or peak-load power when it is needed, This means either that there must be reliable duplicate sources of electricity beyond the normal system essays on nuclear power, or some means of electricity storage.

Means of storing large amounts of electricity as such in giant essays on nuclear power or by other means have not been developed. According to Benjamin K. Sovacoolmost studies critiquing solar and wind energy look only at individual generators and not at the system wide effects of solar and wind farms. Correlations between power swings drop substantially as more solar and wind farms are integrated a process known as geographical smoothing and a wider geographic area also enables a larger pool of energy efficiency efforts to abate intermittency.

Sovacool says that essays on nuclear power renewable energy sources such as wind power and solar energy can displace nuclear resources. This is because wind and solar plants help grid operators handle major outages and contingencies elsewhere in the system, since they generate power in smaller increments that are less damaging than unexpected outages from large plants".

According to a projection by the International Energy Agencysolar power generators may produce most of the world's electricity within 50 years, with wind powerhydroelectricity and biomass plants supplying much of the remaining generation.

As ofthe World Nuclear Association has said essays on nuclear power is unprecedented interest in renewable energy, essays on nuclear power, particularly solar and wind energy, which provide electricity without giving rise to any carbon dioxide emission. Harnessing these for electricity depends on the cost and efficiency of the technology, which is constantly improving, thus reducing costs per peak kilowatt. This approach could contain greenhouse gas levels to less than parts per million, the safe level beyond which climate change becomes catastrophic and irreversible.

The cost of nuclear power has followed an increasing trend [ citation needed ] whereas the cost of electricity is essays on nuclear power in wind power. This has opened up new opportunities and in Indiana, Michigan, and Ohio, the price of power from wind turbines built feet to feet above the ground can now compete with conventional fossil fuels like coal. Prices have fallen to about 4 cents per kilowatt-hour in some cases and utilities have been increasing the amount of wind energy in their portfolio, saying it is their cheapest option.

From a safety stand point, nuclear power, in terms of lives lost per unit of electricity delivered, is comparable to and in some cases, lower than many renewable energy sources.

A nuclear plant needs to be disassembled and removed. Much of the disassembled nuclear plant needs to be stored as low level nuclear waste. Since nuclear power plants are fundamentally heat engineswaste heat disposal becomes an issue at high ambient temperature. Droughts and extended periods of high temperature can "cripple nuclear power generation, and it is often during these times when electricity demand is highest because of air-conditioning and refrigeration loads and diminished hydroelectric capacity".

The economics of new nuclear power plants is a controversial subject, since there are diverging views on this topic, and multibillion-dollar investments ride on the choice of an energy source. Nuclear power plants typically have high capital costs for building the plant, but low essays on nuclear power fuel costs with much of the costs of fuel extraction, processing, use and long-term storage externalized, essays on nuclear power.

Therefore, comparison with other power generation methods is strongly dependent on assumptions about construction timescales and capital financing for nuclear plants. Cost estimates also need to take into account plant decommissioning and nuclear waste storage costs. On the other hand, measures to mitigate global warmingsuch as a carbon tax or carbon emissions tradingmay favor the economics of nuclear power. In recent years there has been a slowdown of electricity demand growth and financing has become more difficult, which impairs large projects such as nuclear reactors, with very large upfront costs and long project cycles which carry a large variety of risks.

Analysis of the economics of nuclear power must take into account who bears the risks of future uncertainties. To date all operating nuclear power plants were developed by state-owned or regulated utility monopolies [62] where many of the risks associated with construction costs, operating performance, fuel price, and other factors were borne by consumers rather than suppliers.

Many countries essays on nuclear power now liberalized the electricity market where these risks, and the risk of cheaper competitors emerging before capital costs are recovered, are borne by plant suppliers and operators rather than consumers, which leads to a significantly different evaluation of the economics of new nuclear power plants. Following the Fukushima Daiichi nuclear disasteressays on nuclear power, costs are likely to go up for currently operating and new nuclear essays on nuclear power plants, due to increased requirements for on-site spent fuel management and elevated design essays on nuclear power threats.

New nuclear power plants require significant upfront investment which was so far mostly caused by highly customized designs of large plants but can be driven down by standardized, reusable designs as did South Korea [65].

While new nuclear power plants are more expensive than new renewable energy in upfront investment, the cost of the essays on nuclear power is expected to grow as the grid is saturated with intermittent sources and energy storage as well as land usage becomes a primary barrier to their essays on nuclear power. In International Energy Agency called for creation of a global nuclear power licensing framework as in the existing legal situation each plant design needs to be licensed separately in each country.

The price of energy inputs and the environmental costs of every nuclear power plant continue long after the facility has finished generating its last useful electricity. Both nuclear reactors and uranium enrichment facilities must be decommissioned, [ citation needed ] returning the facility and its parts to a safe enough level to be entrusted for other uses.

After a cooling-off period that may last as long as a century, [ citation needed ] reactors must be dismantled and cut into small pieces to be packed in containers for final disposal. The process is very expensive, time-consuming, potentially hazardous to the natural environment, and presents new opportunities for human error, accidents or sabotage. In the U. there are 13 reactors that have permanently shut down and are in some phase of decommissioning, and none of them have completed the process.

Current UK plants are expected to exceed £ 73 billion in decommissioning costs. Critics of nuclear power claim that it is the beneficiary of inappropriately large economic subsidiestaking the form of research and development, financing support for building new reactors and decommissioning old reactors and waste, and that these subsidies are often overlooked when comparing the economics of nuclear against other forms of power generation.

Nuclear power proponents argue that competing energy sources also receive subsidies. Fossil fuels receive large direct and indirect subsidies, such as tax benefits and not having to pay for the greenhouse gases they emit, essays on nuclear power, such as through a carbon tax.

Renewable energy sources receive proportionately large direct production subsidies and tax breaks in many nations, although in absolute terms they are often less than subsidies received by non-renewable energy sources. A report by Global Subsidies Initiative compared relative subsidies of most common energy sources. It found that nuclear energy receives 1. Carbon taxation is a significant positive driver in the economy of both nuclear plants and renewable energy sources, all of which are low emissions in their life-cycle greenhouse-gas emissions.

In a heated debate happened in the European Union on creation of a "green finance taxonomy" list intended to create investment opportunities for zero-emission energy technologies. Under lobbying from European Greens and Germany an additional "do no harm" criterion was introduced specifically to exclude nuclear power which in their intention should exclude nuclear power from the list.

In July W. Essays on nuclear power Moore, former Liberia 's Minister for Public Works, called international bodies to start or restart funding for nuclear projects in Africa, essays on nuclear power, following the example of US Development Finance Corporation. Moore accused high-income countries like Germany and Australia of "hypocrisy" and "pulling up the ladder behind them", as they have built their strong economy over decades of cheap fossil or nuclear power, and now are effectively preventing African countries from using the only low-carbon and non-intermittent alternative, the nuclear power.

Also in July Hungary declared its nuclear power will be used as low-emission source of energy to produce hydrogen, [82] while Czechia began the process of approval of public loan to CEZ nuclear power station. Kristin Shrader-Frechette has said "if reactors were safe, nuclear industries would not demand government-guaranteed, accident-liability protection, as a condition for their generating electricity".

The potential costs resulting from a nuclear accident including one caused by a terrorist attack or a natural disaster are great. The liability of owners of nuclear power plants in the U. is currently limited under the Price-Anderson Act PAA. The Price-Anderson Act, introduced inwas "an implicit admission that nuclear power provided risks that producers were unwilling to assume without federal backing". Without such protection, private companies were unwilling to be involved.

No other technology in the history of American industry has enjoyed such continuing blanket protection. The PAA was due to expire inessays on nuclear power, and the former U.

vice-president Dick Cheney said in that "nobody's going to invest in nuclear power plants" if the PAA is not renewed. InU. Nuclear Regulatory Commission USNRC concluded that the liability limits placed on nuclear insurance were significant enough to constitute a subsidy, but did not attempt to quantify the value of such a subsidy at that time.
