There are large variations in people's understanding of the issues surrounding nuclear power, including the technology itself, climate change mitigation, and energy security. Proponents of nuclear energy contend that nuclear power is a sustainable energy source that reduces carbon emissions and increases energy security by decreasing dependence on imported energy sources. Opponents believe that nuclear power poses many threats to people and the environment. While nuclear power has historically been opposed by many environmentalist organisations, some support it, as do some scientists.
Nuclear energy is often considered to be a controversial area of public policy. [1] [2] The debate about nuclear power peaked during the 1970s and 1980s, when it "reached an intensity unprecedented in the history of technology controversies", in some countries. [3] [4]
Proponents of nuclear energy point to the fact that nuclear power produces very little conventional air pollution, greenhouse gases, and smog, in contrast to fossil fuel sources of energy. [5] Proponents also argue that perceived risks of storing waste are exaggerated, and point to an operational safety record in the Western world which is excellent in comparison to the other major kinds of power plants. [6] Historically, there have been numerous proponents of nuclear energy, including Georges Charpak, Glenn T. Seaborg, Edward Teller, Alvin M. Weinberg, Eugene Wigner, Ted Taylor, and Jeff Eerkens. There are also scientists who write favorably about nuclear energy in terms of the broader energy landscape, including Robert B. Laughlin, Michael McElroy, and Vaclav Smil. In particular, Laughlin writes in "Powering the Future" (2011) that expanded use of nuclear power will be nearly inevitable, either because of a political choice to leave fossil fuels in the ground, or because fossil fuels become depleted.
Globally, there are dozens of companies with an interest in the nuclear industry, including Areva, BHP, Cameco, China National Nuclear Corporation, EDF, Iberdrola, Nuclear Power Corporation of India, Ontario Power Generation, Rosatom, Tokyo Electric Power Company, and Vattenfall. Many of these companies lobby politicians and others about nuclear power expansion, undertake public relation activities, petition government authorities, as well as influence public policy through referendum campaigns and involvement in elections. [7] [8] [9] [10] [11]
The nuclear industry has "tried a variety of strategies to persuade the public to accept nuclear power", including the publication of numerous "fact sheets" that discuss issues of public concern. [12] Nuclear proponents have worked to boost public support by offering newer, safer, reactor designs. These designs include those that incorporate passive safety and Small Modular Reactors.
Since 2000 the nuclear industry has undertaken an international media and lobbying campaign to promote nuclear power as a solution to the greenhouse effect and climate change. Though reactor operation is free of carbon dioxide emissions, other stages of the nuclear fuel chain – from uranium mining, to reactor decommissioning and radioactive waste management – use fossil fuels and hence emit carbon dioxide.
The Nuclear Energy Institute has formed various sub-groups to promote nuclear power. These include the Washington-based Clean and Safe Energy Coalition, which was formed in 2006 and led by Patrick Moore. Christine Todd Whitman, former head of the USEPA has also been involved. Clean Energy America is another group also sponsored by the NEI. [13]
In Britain, James Lovelock well known for his Gaia Hypothesis began to support nuclear power in 2004. He is patron of the Supporters of Nuclear Energy. SONE also recognise that there are serious technical challenges associated with an electric grid reliant on intermittent and low density sources of energy. The main nuclear lobby group in Britain is FORATOM. [13]
As of 2014, the U.S. nuclear industry has begun a new lobbying effort, hiring three former senators — Evan Bayh, a Democrat; Judd Gregg, a Republican; and Spencer Abraham, a Republican — as well as William M. Daley, a former staffer to President Obama. The initiative is called Nuclear Matters, and it has begun a newspaper advertising campaign. [14]
In March 2017, a bipartisan group of eight senators, including five Republicans and three Democrats introduced S. 512, the Nuclear Energy Innovation and Modernization Act (NEIMA). The legislation would help to modernize the Nuclear Regulatory Commission (NRC), support the advancement of the nation's nuclear industry and develop the regulatory framework to enable the licensing of advanced nuclear reactors, while improving the efficiency of uranium regulation. Letters of support for this legislation were provided by thirty-six organizations, including for profit enterprises, non-profit organizations and educational institutions. The most prominent entities from that group and other well-known organizations actively supporting the continued or expanded use of nuclear power as a solution for providing clean, reliable energy include:
The United States generates about 19% of its electricity from nuclear power plants. Nearly 60% of all clean energy generated in the U.S. comes from nuclear power.[ citation needed ] Studies have shown that closing a nuclear power plant results in greatly increased carbon emissions as only burning coal or natural gas can make up for the massive amount of energy lost from a nuclear power plant.[ citation needed ] Even though there have long been protests against nuclear power, the effect of long-term scrutiny has elevated safety within the industry, making nuclear power the safest form of energy in operation today, despite the fact that many continue to fear it.[ citation needed ] Nuclear power plants create thousands of jobs, many in health and safety jobs, and seldom experience protests from area residents, as they bring large amounts of economic activity, attract educated employees and leave the air clear safe, unlike oil, coal or gas plants, which bring disease and environmental damage to their workers and neighbors.[ citation needed ] Nuclear engineers have traditionally worked, directly or indirectly, in the nuclear power industry, in academia or for national laboratories. More recently, young nuclear engineers have started to innovate and launch new companies, becoming entrepreneurs in order to bring their enthusiasm for using the power of the atom to address the climate crisis. As of June 2015, Third Way released a report identifying 48 nuclear start-ups or projects organized to work on nuclear innovations in what is being called "advanced nuclear" designs. [21] Current research in the industry is directed at producing economical, proliferation-resistant reactor designs with passive safety features. Although government labs research the same areas as industry, they also study a myriad of other issues such as nuclear fuels and nuclear fuel cycles, advanced reactor designs, and nuclear weapon design and maintenance. A principal pipeline for trained personnel for US reactor facilities is the Navy Nuclear Power Program. The job outlook for nuclear engineering from the year 2012 to the year 2022 is predicted to grow 9% due to many elder nuclear engineers retiring, safety systems needing to be updated in power plants, and the advancements made in nuclear medicine. [22]
A pragmatic need for secure energy supply is a leading reason for many to support nuclear energy. Many people, including former opponents of nuclear energy, now say that nuclear energy is necessary for reducing carbon dioxide emissions. They recognize that the threat to humanity from climate change is far worse than any risk associated with nuclear energy. Many nuclear energy supporters, but not all, acknowledge that renewable energy is also important to the effort to eliminate emissions. Early environmentalists who publicly voiced support for nuclear power include James Lovelock, originator of the Gaia hypothesis, Patrick Moore, an early member of Greenpeace and former president of Greenpeace Canada, George Monbiot and Stewart Brand, creator of the Whole Earth Catalog. [23] [24] Lovelock goes further to refute claims about the danger of nuclear energy and its waste products. [25] In a January 2008 interview, Moore said that "It wasn't until after I'd left Greenpeace and the climate change issue started coming to the forefront that I started rethinking energy policy in general and realized that I had been incorrect in my analysis of nuclear as being some kind of evil plot." [26] There are increasing numbers of scientists and laymen who are environmentalists with views that depart from the mainstream environmental stance that rejects a role for nuclear power in the climate fight (once labelled "Nuclear Greens," [27] some now consider themselves Ecomodernists).
Other academics and professionals, alarmed by the exaggerated impact media coverage of nuclear accidents have formed a group called Scientists for Accurate Radiation Information (SARI). [28] This was formed after a tsunami in Japan in 2011 caused an accidental release at Fukushima Daiichi, local people were unnecessarily relocated and psychologically stressed by false fears. This evacuation is estimated to have produced increased mortality rates equivalent to 2,313 deaths. [29] This effective suffering is known as the ‘nocebo’ effect, and describes a situation where a negative outcome occurs due to a belief that an intervention will cause harm.
Others who have spoken publicly on the benefits of nuclear power include:
Climate and energy scientists in 2013: there is no credible path to climate stabilization that does not include a substantial role for nuclear power [69] [70] [71] [72]
Conservation biologists in 2014: to replace the burning of fossil fuels, if we are to have any chance of mitigating severe climate change […we] need to accept a substantial role for advanced nuclear power systems with complete fuel recycling [73] [74] [75]
The following is a list of people that signed the open letter: [76]
The International Thermonuclear Experimental Reactor, located in France, is the world's largest and most advanced experimental tokamak nuclear fusion reactor project. A collaboration between the European Union (EU), India, Japan, China, Russia, South Korea and the United States, the project aims to make a transition from experimental studies of plasma physics to electricity-producing fusion power plants. However, the World Nuclear Association says that nuclear fusion "presents so far insurmountable scientific and engineering challenges". [78] Construction of the ITER facility began in 2007, but the project has run into many delays and budget overruns. The facility is now not expected to begin operations until the year 2027 – 11 years after initially anticipated. [79]
Another nuclear power program is the Energy Impact Center's OPEN100 project. OPEN100 was launched in 2020 and has published open-source blueprints for a nuclear power plant with a 100-megawatt pressurized water reactor. [80] The project aims to minimize the costs and duration of construction to increase nuclear power supply and potentially reverse the effects of climate change. [81]
Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear fission of uranium and plutonium in nuclear power plants. Nuclear decay processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as Voyager 2. Generating electricity from fusion power remains the focus of international research.
Energy development is the field of activities focused on obtaining sources of energy from natural resources. These activities include the production of renewable, nuclear, and fossil fuel derived sources of energy, and for the recovery and reuse of energy that would otherwise be wasted. Energy conservation and efficiency measures reduce the demand for energy development, and can have benefits to society with improvements to environmental issues.
Patrick Albert Moore is a Canadian industry consultant, former activist, an early member and past president of Greenpeace Canada. Since leaving Greenpeace in 1986, Moore has criticized the environmental movement for what he sees as scare tactics and disinformation, saying that the environmental movement "abandoned science and logic in favor of emotion and sensationalism". Greenpeace has criticized Moore, calling him "a paid spokesman for the nuclear industry, the logging industry, and genetic engineering industry" who "exploits long-gone ties with Greenpeace to sell himself as a speaker and pro-corporate spokesperson".
Mark Lynas is a British author and journalist whose work is focused on environmentalism and climate change. He has written for the New Statesman, The Ecologist, Granta and Geographical magazines, and The Guardian and The Observer newspapers in the UK, as well as the New York Times and Washington Post in the United States; he also worked on and appeared in the film The Age of Stupid. He was born in Fiji, grew up in Peru, Spain and the United Kingdom and holds a degree in history and politics from the University of Edinburgh. He has published several books including Six Degrees: Our Future on a Hotter Planet (2007) and The God Species: Saving the Planet in the Age of Humans (2011). Lynas is research and climate lead for the Alliance for Science and is co-founder of the pro-science environmental network RePlanet. Since 2009 he has been climate advisor to former president of the Maldives Mohamed Nasheed, and he currently works to assist Nasheed with the Climate Vulnerable Forum, a group of the world's most climate-vulnerable 58 developing countries. He is a strategic advisor for the international ecomodernist NGO WePlanet. He has co-authored a number of peer-reviewed scientific publications, including a 2021 paper which found that the consensus on anthropogenic climate change in the scholarly literature now exceeds 99%.
The anti-nuclear movement is a social movement that opposes various nuclear technologies. Some direct action groups, environmental movements, and professional organisations have identified themselves with the movement at the local, national, or international level. Major anti-nuclear groups include Campaign for Nuclear Disarmament, Friends of the Earth, Greenpeace, International Physicians for the Prevention of Nuclear War, Peace Action, Seneca Women's Encampment for a Future of Peace and Justice and the Nuclear Information and Resource Service. The initial objective of the movement was nuclear disarmament, though since the late 1960s opposition has included the use of nuclear power. Many anti-nuclear groups oppose both nuclear power and nuclear weapons. The formation of green parties in the 1970s and 1980s was often a direct result of anti-nuclear politics.
In the United States, nuclear power is provided by 94 commercial reactors with a net capacity of 97 gigawatts (GW), with 63 pressurized water reactors and 31 boiling water reactors. In 2019, they produced a total of 809.41 terawatt-hours of electricity, which accounted for 20% of the nation's total electric energy generation. In 2018, nuclear comprised nearly 50 percent of US emission-free energy generation.
The Nuclear Energy Institute (NEI) is a nuclear industry trade association in the United States, based in Washington, D.C.
The anti-nuclear movement in the United States consists of more than 80 anti-nuclear groups that oppose nuclear power, nuclear weapons, and/or uranium mining. These have included the Abalone Alliance, Clamshell Alliance, Committee for Nuclear Responsibility, Nevada Desert Experience, Nuclear Information and Resource Service, Physicians for Social Responsibility, Plowshares Movement, United Steelworkers of America (USWA) District 31, Women Strike for Peace, Nukewatch, and Women's International League for Peace and Freedom. Some fringe aspects of the anti-nuclear movement have delayed construction or halted commitments to build some new nuclear plants, and have pressured the Nuclear Regulatory Commission to enforce and strengthen the safety regulations for nuclear power plants. Most groups in the movement focus on nuclear weapons.
Jim Green is an anti-nuclear campaigner with Friends of the Earth Australia. Green is a regular media commentator on nuclear issues. He has an honours degree in public health from the University of Wollongong and was awarded a PhD in science and technology studies for his analysis of the Lucas Heights research reactor debates.
Michael D. Shellenberger is a professor, author, and journalist who writes on a wide range of topics including free speech, homelessness, and the environment. He is a co-founder of the Breakthrough Institute and the California Peace Coalition. Shellenberger founded the pro-nuclear non-profit Environmental Progress in 2016.
Nuclear power in Australia has been a topic of debate since the 1930s. Australia has one nuclear reactor at Lucas Heights, New South Wales, although it is only used to produce radionuclides for nuclear medicine, and does not produce electricity. Australia hosts 33% of the world's proven uranium deposits, and is currently the world’s third largest producer of uranium after Kazakhstan and Canada.
The nuclear power debate is a long-running controversy about the risks and benefits of using nuclear reactors to generate electricity for civilian purposes. The debate about nuclear power peaked during the 1970s and 1980s, as more and more reactors were built and came online, and "reached an intensity unprecedented in the history of technology controversies" in some countries. In the 2010s, 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 was a resurgence in the intensity of the nuclear power debate.
Stephen Tindale was a British environmentalist who was the executive director of Greenpeace in the United Kingdom from 2000 to 2005. He was director of The Alvin Weinberg Foundation, co-founder of the organisation Climate Answers, associate fellow at the Centre for European Reform and co-author of Repowering Communities with Prashant Vaze.
Whole Earth Discipline: An Ecopragmatist Manifesto is the sixth book by Stewart Brand, published by Viking Penguin in 2009. He sees Earth and people propelled by three transformations: climate change, urbanization and biotechnology. Brand tackles "touchy issues" like nuclear power, genetic engineering and geoengineering, "fully aware that many of the environmentalist readers he hopes to reach will start out disagreeing with him".
Barry William Brook is an Australian scientist. He is an ARC Australian Laureate Professor and Chair of Environmental Sustainability at the University of Tasmania in the Faculty of Science, Engineering & Technology. He was formerly an ARC Future Fellow in the School of Earth and Environmental Sciences at the University of Adelaide, Australia, where he held the Sir Hubert Wilkins Chair of Climate Change from 2007 to 2014. He was also Director of Climate Science at the Environment Institute.
In December 2016, the Jordan Atomic Energy Commission (JAEC), in cooperation with a consortium headed by the Korean Atomic Energy Research Institute, inaugurated the 5 MW Jordan Research and Training Reactor. The facility is the first nuclear reactor in the country. It will provide radioactive isotopes for medical usage in Jordan, and will provide training for students at the University to produce a skilled workforce for the country's planned commercial nuclear reactors.
The following outline is provided as an overview of and topical guide to nuclear power:
The Doomsday Machine: The High Price of Nuclear Energy, the World's Most Dangerous Fuel is a 2012 book by Martin Cohen and Andrew McKillop which addresses a broad range of concerns regarding the nuclear industry, the economics and environmental aspects of nuclear energy, nuclear power plants, and nuclear accidents. The book has been described by The New York Times as "a polemic on the evils of splitting the atom".
Pandora's Promise is a 2013 documentary film about the nuclear power debate, directed by Robert Stone. Its central argument is that nuclear power, which still faces historical opposition from environmentalists, is a relatively safe and clean energy source that can help mitigate the serious problem of anthropogenic global warming.
Benjamin "Ben" Heard is a South Australian environmental consultant and an advocate for nuclear power in Australia, through his directorship of environmental NGO, Bright New World.

(help)At the most fundamental level I'm an environmentalist. I'm doing this because I think nuclear power is the best way of producing large amounts of carbon-free electricity. I think the world needs nuclear power, alongside solar, wind, hydro, and geothermal, if we want to have any hope of reducing fossil fuel emissions and preventing global climate change.
