Nuclear power phase-out
A nuclear power phase-out is the discontinuation of usage of nuclear power for energy production. Often initiated because of concerns about nuclear power, phase-outs usually include shutting down nuclear power plants and looking towards fossil fuels and renewable energy.
Three nuclear accidents have influenced the discontinuation of nuclear power: the 1979 Three Mile Island partial nuclear meltdown in the United States, the 1986 Chernobyl disaster in the USSR, and the 2011 Fukushima nuclear disaster in Japan.
Following the March 2011 Fukushima nuclear disaster, Germany has permanently shut down eight of its 17 reactors and pledged to close the rest by the end of 2022. Italy voted overwhelmingly to keep their country non-nuclear. Switzerland and Spain have banned the construction of new reactors. Japan’s prime minister has called for a dramatic reduction in Japan’s reliance on nuclear power. Taiwan’s president did the same. Shinzō Abe, the new prime minister of Japan since December 2012, announced a plan to re-start some of the 54 Japanese nuclear power plants (NPPs) and to continue some NPP sites under construction.
As of 2016, countries including Australia, Austria, Denmark, Greece, Ireland, Italy, Latvia, Liechtenstein, Luxembourg, Malaysia, Malta, New Zealand, Norway, Philippines, and Portugal have no nuclear power stations and remain opposed to nuclear power. Belgium, Germany, Spain and Switzerland are phasing-out nuclear power. Globally, more nuclear power reactors have closed than opened in recent years but overall capacity has increased.
Italy is the only country that has closed all of functioning nuclear plants. Lithuania, Kazakhstan have shut down their only nuclear plants, but plan to built new ones to replace them. Armenia shut down its only nuclear plant but subsequently restarted it. Austria never used its first nuclear plant that was completely built. Due to financial, politic and technical reasons Cuba, Libya, North Korea and Poland never completed the construction of their first nuclear plants (although North Korea and Poland plan to). Azerbaijan, Georgia, Ghana, Ireland, Kuwait, Oman, Peru, Singapore, Venezuela have planned, but not constructed their first nuclear plants.

A popular movement against nuclear power has gained strength in the Western world, based on concerns about more nuclear accidents and concerns about nuclear waste. Anti-nuclear critics see nuclear power as a dangerous, expensive way to boil water to generate electricity. The 1979 Three Mile Island accident and the 1986 Chernobyl disaster played a key role in stopping new plant construction in many countries. Major anti-nuclear power groups include Friends of the Earth, Greenpeace, Institute for Energy and Environmental Research, Nuclear Information and Resource Service, and Sortir du nucléaire (France).
Several countries, especially European countries, have abandoned the construction of new of nuclear power plants. Austria (1978), Sweden (1980) and Italy (1987) voted in referendums to oppose or phase out nuclear power, while opposition in Ireland prevented a nuclear program there. Countries that have no nuclear plants and have restricted new plant constructions comprise Australia, Austria, Denmark, Greece, Italy, Ireland and Norway. Poland stopped the construction of a plant. Belgium, Germany, Spain, and Sweden decided not to build new plants or intend to phase out nuclear power, although still mostly relying on nuclear energy.
New reactors under construction in Finland and France, which were meant to lead a nuclear new build, have been substantially delayed and are running over-budget. However, China has 27 new reactors under construction, and there are also new reactors being built in Belarus, Brazil, India, Japan, Pakistan, Russia, Slovakia, South Korea, Turkey, United Arab Emirates ,United Kingdom and the United States of America. At least 100 older and smaller reactors will "most probably be closed over the next 10-15 years".
Countries that wish to shut down nuclear power plants must find alternatives for electricity generation; otherwise, they are forced to become dependent on imports. Therefore, the discussion of a future for nuclear energy is intertwined with discussions about fossil fuels or an energy transition to renewable energy.
Countries that have decided on a phase-out
A nuclear power station was built during the 1970s at Zwentendorf, Austria, but its start-up was prevented by a popular vote in 1978. On July 9, 1997, the Austrian Parliament voted unanimously to maintain the country's anti-nuclear policy.
Belgium's nuclear phase-out legislation was agreed in July 1999 by the Liberals (VLD and MR), the Socialists (SP.A and PS) and the Greens party (Groen! and Ecolo). The phase-out law calls for each of Belgium's seven reactors to close after 40 years of operation with no new reactors built subsequently. When the law was being passed, it was speculated it would be overturned again as soon as an administration without the Greens was in power.
In 2003, a new government was elected without the Greens. In September 2005, the government decided to partially overturn the previous decision, extending the phase-out period for another 20 years, with possible further extensions. It remains unknown if additional nuclear plants will be built.
In July 2005, the Federal Planning Bureau published a new report, which states that oil and other fossil fuels generate 90% of Belgian energy use, while nuclear power accounts for 9% and renewable energy for 1%. Electricity only amounts to 16% of total energy use, and while nuclear-powered electricity amounts to 9% of use in Belgium, in many parts of Belgium, especially in Flanders, it makes up more than 50% of the electricity provided to households and businesses. This was one of the major reasons to revert the earlier phase-out, since it was impossible to provide more than 50% of the electricity by 'alternative' energy-production, and a revert to the classical coal-driven electricity would mean inability to adhere to the Kyoto Protocol.
It is projected that within 25 years renewable energy will increase to at most 5% of the energy use, because of high costs. The current plan of the government is for all nuclear power stations to shut down by 2025. The report raises concerns about greenhouse gases and sustainability.
In August 2005, French SUEZ offered to buy the Belgian Electrabel, which runs nuclear power stations. At the end of 2005, Suez had some 98.5% of all Electrabel shares. Beginning 2006, Suez and Gaz de France announced a merger.
In 2000, the German government, consisting of the SPD and Alliance '90/The Greens, officially announced its intention to phase out the use of nuclear energy. The power plants in Stade and Obrigheim were turned off on 14 November 2003, and 11 May 2005, respectively. The plants' dismantling was scheduled to begin in 2007.
The year 2000 Renewable Energy Sources Act provided for a feed-in tariff in support of renewable energy. The German government, declaring climate protection as a key policy issue, announced a carbon dioxide reduction target by the year 2005 compared to 1990 by 25%. In 1998, the use of renewables in Germany reached 284 PJ of primary energy demand, which corresponds to 5% of the total electricity demand. By 2010, the German government wanted to reach 10%.
Anti-nuclear activists have argued the German government had been supportive of nuclear power by providing financial guarantees for energy providers. Also it has been pointed out, there were, as yet, no plans for the final storage of nuclear waste. By tightening safety regulations and increasing taxation, a faster end to nuclear power could have been forced. A gradual closing down of nuclear power plants had come along with concessions in questions of safety for the population with transport of nuclear waste throughout Germany. This latter point has been disagreed with by the Minister of Environment, Nature Conservation and Nuclear Safety.
Critics of a phase-out in Germany argue that the power output from the nuclear power stations will not be adequately compensated and predict an energy crisis. They also argue that only coal-powered plants could compensate for nuclear power and CO2 emissions will increase tremendously (with the use of oil and fossils). Energy may have to be imported from France's nuclear power facilities or Russian natural gas, despite Russia's not being perceived as a safe partner in much of Western Europe.
In 2011, Deutsche Bank analysts concluded that "the global impact of the Fukushima accident is a fundamental shift in public perception with regard to how a nation prioritizes and values its populations health, safety, security, and natural environment when determining its current and future energy pathways". There were many anti-nuclear protests and, on 29 May 2011, Merkel's government announced that it would close all of its nuclear power plants by 2022. Following the March 2011 Fukushima nuclear disaster, Germany has permanently shut down eight of its 17 reactors. Between 2011 and 2014 Germany burned more coal, an additional 9.5 million tonnes of oil equivalent. Galvanised by the Fukushima nuclear disaster, first anniversary anti-nuclear demonstrations were held in Germany in March 2012. Organisers say more than 50,000 people in six regions took part.
The German Energiewende designates a significant change in energy policy from 2010. The term encompasses a transition by Germany to a low carbon, environmentally sound, reliable, and affordable energy supply. On 6 June 2011, following Fukushima, the government removed the use of nuclear power as a bridging technology as part of their policy.
In September 2011, German engineering giant Siemens announced it will withdraw entirely from the nuclear industry, as a response to the Fukushima nuclear disaster in Japan, and said that it would no longer build nuclear power plants anywhere in the world. The company’s chairman, Peter Löscher, said that "Siemens was ending plans to cooperate with Rosatom, the Russian state-controlled nuclear power company, in the construction of dozens of nuclear plants throughout Russia over the coming two decades". Also in September 2011, IAEA Director General Yukiya Amano said the Japanese nuclear disaster "caused deep public anxiety throughout the world and damaged confidence in nuclear power".
A 2016 study shows that the security of electricity supply in Germany has improved in 2014 despite dropping after the nuclear phaseout. The study was conducted near the halfway point of the phaseout, 9 plants having been shut and a further 8 still in operation. Between 2011 and 2015 Germany's use of fossil fuels for electricity increased.
In early-October 2016 Vattenfall began litigation against the German government for its 2011 decision to accelerate the phase-out of nuclear power. Hearing are taking place at the World Bank's International Centre for Settlement of Investment Disputes (ICSID) in Washington DC and Vattenfall is claiming almost €4.7 billion in damages. The German government regards the action as "inadmissible and unfounded".
Nuclear power phase-out commenced in Italy in 1987, one year after the Chernobyl accident. Following a referendum in that year, Italy's four nuclear power plants were closed down, the last in 1990. A moratorium on the construction of new plants, originally in effect from 1987 until 1993, has since been extended indefinitely.
In recent years, Italy has been an importer of nuclear-generated electricity, and its largest electricity utility Enel S.p.A. has been investing in reactors in both France and Slovakia to provide this electricity in the future, and also in the development of the EPR technology.
In October 2005, there was a seminar sponsored by the government about the possibility of reviving Italian nuclear power. The fourth cabinet led by Silvio Berlusconi tried to implement a new nuclear plan but a referendum held in June 2011 stopped any project.
In the Philippines, in 2004, President Gloria Macapagal-Arroyo outlined her energy policy. She wants to increase indigenous oil and gas reserves through exploration, develop alternative energy resources, enforce the development of natural gas as a fuel and coco diesel as alternative fuel, and build partnerships with Saudi Arabia, Asian countries, China and Russia. She also made public plans to convert the Bataan Nuclear Power Plant into a gas-powered facility.
After the Three Mile Island accident in 1979, there was a referendum in 1980 about nuclear power. As a result of this, the Swedish parliament decided that no further nuclear power plants should be built, and that a nuclear power phase-out should be completed by 2010.
After the 1986 Chernobyl disaster in Ukraine, the question of security of nuclear energy was again raised. In 1997, the Riksdag, the Swedish parliament, decided to shut down one of the reactors at Barsebäck by July 1, 1998, and the second before July 1, 2001, although under the condition that their energy production would be compensated. At Barsebäck, block 1 was shut down on November 30, 1999 and block 2 on June 1, 2005.
An opinion poll in April 2016 showed that about half of Swedes want to phase out nuclear power, 30 percent want its use continued, and 20 percent are undecided. Prior to the Fukushima Daiichi nuclear disaster in 2011, "a clear majority of Swedes" had been in favour of nuclear power.
In October 2015, decisions were take to phase out two reactors at Oskarshamn and two at Ringhals, reducing the number of remaining reactors from 12 in 1999 to 6 in 2020. They were shuttered for economical reasons, one of which was high costs for safety upgrades and another lower electricity prices than expected.
The competitive disadvantage for nuclear was partly a result of policy. The renewable portfolio standard (Elcertifikat) system was introduced in 2003 by a parliamentary majority including three anti-nuclear parties and the governing Social Democrats which was in the process of phasing out the Barsebäck power station. The Elcertifikat forced in successively more renewables in the electricity mix. As electricity consumption in Sweden dropped considerably from 2001 on, from about 150 to 140 TWh/year, nuclear power had to compete with subsidised wind power and for a shrinking market.
In June 2016 the opposition parties and the government reached an agreement on Swedish nuclear power. The agreement is to phase out the output tax on nuclear power, and allow ten new replacement reactors to be built at current nuclear plants.
As of 2013[update], the five operational Swiss nuclear reactors were Beznau 1 and 2, Gösgen, Leibstadt, and Mühleberg—all located in the German speaking part of the country. Nuclear power accounted for 36.4% of the national electricity generation, while 57.9% came from hydroelectricity. The remaining 5.7% was generated by other conventional and non-hydro renewable power stations.
On 25 May 2011, the Federal Council decided on a slow phase-out by not extending running times or building new power plants. The first power plant, Mühleberg, will stop running in 2019, the last in 2034.
There have been many Swiss referenda on the topic of nuclear energy, beginning in 1979 with a citizens' initiative for nuclear safety, which was rejected. In 1984, there was a vote on an initiative "for a future without further nuclear power stations" with the result being a 55 to 45% vote against. On September 23, 1990, Switzerland had two more referenda about nuclear power. The initiative "stop the construction of nuclear power stations", which proposed a ten-year moratorium on the construction of new nuclear power plants, was passed with 54.5% to 45.5%. The initiative for a phase-out was rejected with by 53% to 47.1%. In 2000, there was a vote on a green tax for support of solar energy. It was rejected by 67–31%. On May 18, 2003, there were two referenda: "Electricity without Nuclear", asking for a decision on a nuclear power phase-out, and "Moratorium Plus", for an extension of the earlier-decided moratorium on the construction of new nuclear power plants. Both were turned down. The results were: Moratorium Plus: 41.6% Yes, 58.4% No; Electricity without Nuclear: 33.7% Yes, 66.3% No.
The program of the "Electricity without Nuclear" petition was to shut down all nuclear power stations by 2033, starting with Unit 1 and 2 of Beznau nuclear power stations, Mühleberg in 2005, Gösgen in 2009, and Leibstadt in 2014. "Moratorium Plus" was for an extension of the moratorium for another ten years, and additionally a condition to stop the present reactors after 40 years of operation. In order to extend the 40 years by ten more years, another referendum would have to be held (at high administrative costs). The rejection of the Moratorium Plus had come as a surprise to many, as opinion polls before the referendum had showed acceptance. Reasons for the rejections in both cases were seen as the worsened economic situation.
Other significant places
In Ireland, a nuclear power plant was first proposed in 1968. It was to be built during the 1970s at Carnsore Point in County Wexford. The plan called for first one, then ultimately four plants to be built at the site, but it was dropped after strong opposition from environmental groups, and Ireland has remained without nuclear power since. Despite opposing nuclear power (and nuclear fuel reprocessing at Sellafield), Ireland is to open an interconnector to the mainland UK to buy electricity, which is, in some part, the product of nuclear power.
Slovenian nuclear plant in Krško (co-owned with Croatia) is scheduled to be closed by 2023, and there are no plans to build further nuclear plants. The debate on whether and when to close the Krško plant was somewhat intensified after the 2005/06 winter energy crisis. In May 2006 the Ljubljana-based daily Dnevnik claimed Slovenian government officials internally proposed adding a new 1000 MW block into Krško after the year 2020.
Greece operates only a single small nuclear reactor in the Greek National Physics Research Laboratory in Demokritus Laboratories for research purposes.
The future of nuclear power in the United Kingdom is currently under review. The country has a number of reactors which are currently reaching the end of their working life, and it is currently undecided how they will be replaced. The UK is also currently failing to reach its targets for reduction on CO2 emissions, which situation may be made worse if new nuclear power stations are not built. The UK also uses a large proportion of gas-fired power stations, which produce half the CO2 emissions as coal, but there have been recent difficulties in obtaining adequate gas supplies. The UK government has just appointed a new pro-nuclear energy minister.
In the Netherlands, in 1994, the Dutch parliament voted to phase out after a discussion of nuclear waste management. The power station at Dodewaard was shut down in 1997. In 1997 the government decided to end Borssele's operating license, at the end of 2003. In 2003 the shut-down was postponed by the government to 2013. In 2005 the decision was reversed and research in expanding nuclear power has been initiated. Reversal was preceded by the publication of the Christian Democratic Appeal's report on sustainable energy. Other coalition parties then conceded. In 2006 the government decided that Borssele will remain open until 2033, if it can comply with the highest safety standards. The owners, Essent and DELTA will invest 500 million euro in sustainable energy, together with the government, money which the government claims otherwise should have been paid to the plants owners as compensation.
New Zealand enacted the New Zealand Nuclear Free Zone, Disarmament, and Arms Control Act 1987 which prohibits the stationing of nuclear weapons on the territory of New Zealand and the entry into New Zealand waters of nuclear armed or propelled ships. This Act of Parliament, however, does not prevent the construction of nuclear power plants.
In Australia there are no nuclear power plants. Australia has very extensive, low-cost coal reserves and substantial natural gas and majority political opinion is still opposed to domestic nuclear power on both environmental and economic grounds.
For North Korea, two PWRs at Kumho were under construction until that was suspended in November 2003. On September 19, 2005 North Korea pledged to stop building nuclear weapons and agreed to international inspections in return for energy aid, which may include one or more light water reactors – the agreement said "The other parties expressed their respect and agreed to discuss at an appropriate time the subject of the provision of light-water reactor" [sic].
In July 2000, the Turkish government decided not to build four reactors at the controversial Akkuyu Nuclear Power Plant, but later changed its mind. The official launch ceremony took place in April 2015, and the first unit is expected to be completed in 2020.
Taiwan has 3 active plants and 6 reactors. Active seismic faults run across the island, and some environmentalists argue Taiwan is unsuited for nuclear plants. Construction of the Lungmen Nuclear Power Plant using the ABWR design has encountered public opposition and a host of delays, and in April 2014 the government decided to halt construction. Construction will be halted from July 2015 to 2017 in order to allow time for a referendum to be held. The 2016 election was won by a government with stated policies that included phasing out nuclear power generation.
Vietnam had developed detailed plans for 2 nuclear power plants with 8 reactors, but in November 2016 decided to abandon nuclear power plans as they were "not economically viable because of other cheaper sources of power."
Once a nuclear proponent, Prime Minister Naoto Kan became increasingly anti-nuclear following the Fukushima nuclear disaster. In May 2011, he closed the aging Hamaoka Nuclear Power Plant over earthquake and tsunami fears, and said he would freeze plans to build new reactors. In July 2011, Kan said that "Japan should reduce and eventually eliminate its dependence on nuclear energy ... saying that the Fukushima accident had demonstrated the dangers of the technology". In August 2011, the Japanese government passed a bill to subsidize electricity from renewable energy sources. A 2011 Japanese Cabinet energy white paper says "public confidence in safety of nuclear power was greatly damaged" by the Fukushima disaster, and calls for a reduction in the nation's reliance on nuclear power. As of August 2011[update], the crippled Fukushima nuclear plant is still leaking low levels of radioactivity and areas surrounding it could remain uninhabitable for decades.
By March 2012, one year after the disaster, all but two of Japan's nuclear reactors were shut down; some were damaged by the quake and tsunami. The following year, the last two were taken off-line. Authority to restart the others after scheduled maintenance throughout the year was given to local governments, and in all cases local opposition prevented restarting.
Prime Minister Shinzo Abe's government, reelected on a platform of restarting nuclear power, plans to have nuclear power account for 20 to 22 percent of the country’s total electricity supply by 2030, compared with roughly 30 percent before the disaster at the Fukushima complex.
The United States is, as of 2013, undergoing a practical phase-out independent of stated goals and continued official support. This is not due to concerns about the source or anti-nuclear groups, but due to the rapidly falling prices of natural gas and the reluctance of investors to provide funding for long-term projects when short term profitability of turbine power is available.
Through the 2000s a number of factors led to greatly increased interest in new nuclear reactors, including rising demand, new lower-cost reactor designs, and concerns about global climate change. By 2009, about 30 new reactors were planned, and a large number of existing reactors had applied for upgrades to increase their output. In total, 39 reactors have had their licences renewed, three Early Site Permits have been applied for, and three consortiums have applied for Combined Construction-Operating Licences under the Nuclear Power 2010 Program. In addition, the Energy Policy Act of 2005 contains incentives to further expand nuclear power.
However, by 2012 the vast majority of these plans were cancelled, and several additional cancellations followed in 2013. Currently only five new reactors are under construction, and one, at Watts Bar, was originally planned in the 1970s and only under construction now. Construction of the new AP1000 design is underway at two locations in the United States in Georgia and South Carolina. Plans for additional reactors in Florida were cancelled in 2013.
Some smaller reactors operating in deregulated markets have become uneconomic to operate and maintain, due to competition from generators using low priced natural gas, and may be retired early. The 556 MWe Kewaunee Power Station is being closed 20 years before license expiry for these economic reasons. Duke Energy's Crystal River 3 Nuclear Power Plant in Florida closed, as it could not recover the costs needed to fix its containment building.
As a result of these changes, after reaching peak production in 2007, US nuclear capacity has been undergoing constant reduction every year.
In Brazil, nuclear energy, produced by two reactors at Angra, accounts for about 4% of the country's electricity – about 13 TWh per year. Angra III is under construction and due to come online in 2018. Brazil plans to build seven more reactors by 2025.
In Argentina, about 6% of the electricity comes from 3 operational reactors: The Embalse Río Tercero plant, a CANDU6 reactor, the Atucha 1 plant, a PHWR German design, and the Atucha 2 plant, also a PHWR German design. Argentina also has some other research reactors, and exports nuclear technology.
Pros and cons of nuclear power
The nuclear debate
The nuclear power debate is about the controversy which has surrounded the deployment and use of nuclear fission reactors to generate electricity from nuclear fuel for civilian purposes. 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.
Proponents of nuclear energy argue that nuclear power is a sustainable energy source which reduces carbon emissions and can increase energy security if its use supplants a dependence on imported fuels. Proponents advance the notion that nuclear power produces virtually no air pollution, in contrast to the chief viable alternative of fossil fuel. Proponents also believe that nuclear power is the only viable course to achieve energy independence for most Western countries. They emphasize that the risks of storing waste are small and can be further reduced by using the latest technology in newer reactors, and the operational safety record in the Western world is excellent when compared to the other major kinds of power plants.
Opponents say that nuclear power poses many threats to people and the environment. These threats include health risks and environmental damage from uranium mining, processing and transport, the risk of nuclear weapons proliferation or sabotage, and the unsolved problem of radioactive nuclear waste. They also contend that reactors themselves are enormously complex machines where many things can and do go wrong, and there have been many serious nuclear accidents. Critics do not believe that these risks can be reduced through new technology. They argue that when all the energy-intensive stages of the nuclear fuel chain are considered, from uranium mining to nuclear decommissioning, nuclear power is not a low-carbon electricity source.
The economics of new nuclear power plants is a controversial subject, since there are diverging views on this topic, and multi-billion dollar investments ride on the choice of an energy source. Nuclear power plants typically have high capital costs for building the plant, but low direct fuel costs (with much of the costs of fuel extraction, processing, use and long term storage externalized). 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 warming, such as a carbon tax or carbon emissions trading, may favor the economics of nuclear power versus fossil fuels.
In recent years there has been a slowdown of electricity demand growth and financing has become more difficult, which affects large projects such as nuclear reactors, with very large upfront costs and long project cycles which carry a large variety of risks. In Eastern Europe, a number of long-established projects are struggling to find finance, notably Belene in Bulgaria and the additional reactors at Cernavoda in Romania, and some potential backers have pulled out. Where cheap gas is available and its future supply relatively secure, this also poses a major problem for nuclear projects.
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 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 have 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 2011 Fukushima Daiichi nuclear disaster, costs are likely to go up for currently operating and new nuclear power plants, due to increased requirements for on-site spent fuel management and elevated design basis threats.
The greenhouse gas emissions from nuclear fission power are small relative to those associated with coal, oil, gas, solar and biomass. They are about equal to those associated with wind and hydroelectric.
The routine health risks from nuclear fission power are very small relative to those associated with coal, oil, gas, solar, biomass, wind and hydroelectric.
However, there is a "catastrophic risk" potential if containment fails, which in nuclear reactors can be brought about by over-heated fuels melting and releasing large quantities of fission products into the environment. The public is sensitive to these risks and there has been considerable public opposition to nuclear power. Even so, in comparing the fatalities for major accidents alone in the energy sector it is still found that the risks associated with nuclear power are extremely small relative to those associated with coal, oil, gas and hydroelectric.
The 1979 Three Mile Island accident and 1986 Chernobyl disaster, along with high construction costs, ended the rapid growth of global nuclear power capacity. A further disastrous release of radioactive materials followed the 2011 Japanese tsunami which damaged the Fukushima I Nuclear Power Plant, resulting in hydrogen gas explosions and partial meltdowns classified as a Level 7 event. The large-scale release of radioactivity resulted in people being evacuated from a 20 km exclusion zone set up around the power plant, similar to the 30 km radius Chernobyl Exclusion Zone still in effect.
The effect of nuclear accidents has been a topic of debate practically since the first nuclear reactors were constructed. It has also been a key factor in public concern about nuclear facilities. Some technical measures to reduce the risk of accidents or to minimize the amount of radioactivity released to the environment have been adopted. Despite the use of such measures, human error remains, and "there have been many accidents with varying effects as well near misses and incidents".
Benjamin K. Sovacool has reported that worldwide there have been 99 accidents at nuclear power plants. Fifty-seven accidents have occurred since the Chernobyl disaster, and 57% (56 out of 99) of all nuclear-related accidents have occurred in the USA. Serious nuclear power plant accidents include the Fukushima Daiichi nuclear disaster (2011), Chernobyl disaster (1986), Three Mile Island accident (1979), and the SL-1 accident (1961). Stuart Arm states, "apart from Chernobyl, no nuclear workers or members of the public have ever died as a result of exposure to radiation due to a commercial nuclear reactor incident."
Nuclear safety and security covers the actions taken to prevent nuclear and radiation accidents or to limit their consequences. This covers nuclear power plants as well as all other nuclear facilities, the transportation of nuclear materials, and the use and storage of nuclear materials for medical, power, industry, and military uses.
Although there is no way to guarantee that a reactor will always be designed, built and operated safely, the nuclear power industry has improved the safety and performance of reactors, and has proposed safer reactor designs, though many of these designs have yet to be tested at industrial or commercial scales. Mistakes do occur and the designers of reactors at Fukushima in Japan did not anticipate that a tsunami generated by an earthquake would disable the backup systems that were supposed to stabilize the reactor after the earthquake. According to UBS AG, the Fukushima I nuclear accidents have cast doubt on whether even an advanced economy like Japan can master nuclear safety. Catastrophic scenarios involving terrorist attacks are also conceivable.
An interdisciplinary team from MIT have estimated that given the expected growth of nuclear power from 2005 – 2055, at least four serious nuclear accidents would be expected in that period. To date, there have been five serious accidents (core damage) in the world since 1970 (one at Three Mile Island in 1979; one at Chernobyl in 1986; and three at Fukushima-Daiichi in 2011), corresponding to the beginning of the operation of generation II reactors. This leads to on average one serious accident happening every eight years worldwide. Despite these accidents, the safety record of nuclear power, in terms of lives lost (ignoring nonfatal illnesses) per unit of electricity delivered, is better than every other major source of power in the world, and on par with solar and wind.
The Energy transition is the shift by several countries to sustainable economies by means of renewable energy, energy efficiency and sustainable development. The final goal is the abolishment of coal and other non-renewable energy sources.
Renewable energy encompasses wind, biomass (such as landfill gas and sewage gas), hydropower, solar power (thermal and photovoltaic), geothermal, and ocean power. These renewable sources serve as alternatives to conventional power generation such as coal power, oil power, and natural gas power. Piecemeal measures often have only limited potential, so a timely implementation for the energy transition requires multiple approaches in parallel. Energy conservation and improvements in energy efficiency thus play a major role. An example of an effective energy conservation measure is improved insulation for buildings; an example of improved energy efficiency is cogeneration of heat and power. Smart electric meters can schedule energy consumption for times when electricity is available inexpensively.
Issues exist that currently prevent a shift over to a 100% renewable technologies. There is debate over the environmental impact of solar power, and the environmental impact of wind power. Some argue that the pollution produced and requirement of rare earth elements offsets many of the benefits compared to other alternative power sources such as hydroelectric, geothermal, and nuclear power. According to the 2013 Post Carbon Pathways report, which reviewed many international studies, the key roadblocks are: climate change denial, the fossil fuels lobby, political inaction, unsustainable energy consumption, outdated energy infrastructure, and financial constraints. However, according to a research paper published in 2014, renewable energy by itself, will not be able to stop climate change.
Google spent $30 million on their RE<C project to develop renewable energy and stave off catastrophic climate change. The project was cancelled after concluding that a best-case scenario for rapid advances in renewable energy could only result in emissions 55 percent below the fossil fuel projections for 2050. Current developments towards a 100% renewable energy policy require solutions to low storage capacity, low energy density, and high cost.
