Singapore isn't currently using nuclear energy primarily due to its small size, high population density, and significant safety/waste management challenges, although it's actively studying advanced options like Small Modular Reactors (SMRs) as a potential low-carbon source for the future, balancing risks with decarbonization needs. Key hurdles include limited land for plants and storage, public perception, lack of operational track record for new tech, and the need for robust international waste disposal agreements.
Geothermal energy is not commercially viable in Singapore given the lack of conventional geothermal resources and our small land area. Harnessing wind energy is also not viable, given our low average wind speeds of about 2m/s to 3m/s and lack of land for large-scale application of wind turbines.
While Singapore has yet to make a decision on deploying nuclear energy, the country is “seriously studying” it and is looking closely at advanced nuclear technologies like small modular reactors.
Singapore aims to achieve net-zero carbon emissions by 2050. Its strategy to decarbonise its energy supply includes deploying solar power, importing cleaner electricity, and adopting low-carbon alternatives such as hydrogen production.
As of 2012, countries such as Australia, Austria, Denmark, Estonia, Greece, Ireland, Italy, Latvia, Liechtenstein, Luxembourg, Malta, Portugal, Israel, Serbia, Malaysia, and Norway have no nuclear power reactors and remain opposed to nuclear power.
Australia doesn't have nuclear power primarily due to federal and state laws banning its development, stemming from concerns about cost, safety, environmental risks, and long construction times; this is coupled with strong national renewable energy potential, making nuclear a less attractive, slower, and riskier option compared to solar and wind.
The United States is the largest producer of nuclear power, while France has the largest share of electricity generated by nuclear power, at about 65%. Some countries operated nuclear reactors in the past but currently have no operating nuclear power plants.
Russia and the United States together possess nearly 90% of the world's nuclear weapons, with Russia holding the largest total stockpile and the U.S. having a substantial number of deployed strategic warheads, making them the dominant nuclear powers by far, despite other nations like China, the UK, France, India, Pakistan, Israel, and North Korea also having nuclear arsenals.
The Australian Naval Nuclear Power Safety Bill 2023 also allows for the US and the UK to dump high-level nuclear waste in Australia.
Disadvantages
Although Singapore is not a U.S. treaty ally, many observers consider the U.S. security partnership with the city-state to be one of the strongest in the Indo-Pacific region. In August 2021, the two nations announced new agreements to address climate change, cybersecurity, and supply chain resilience.
Natural gas is used to produce about 95% of Singapore's electricity, with the remainder generated from other sources such as diesel, waste incineration, coal and biomass.
Australia has never had a nuclear power plant, and has only one nuclear reactor (OPAL), the third in a series at Lucas Heights, New South Wales, which have been used exclusively for research, training, and to produce radionuclides for both nuclear medicine and industry.
The rail network will grow to 360km by the early 2030s, while the islandwide cycling path network will extend to about 1,300km. By 2030, electric buses will make up half of the public fleet, and all new car and taxi registrations will be of cleaner energy models.
Today, in Iceland, 90% of houses are heated with geothermal and 10% with electricity but in Reykjavik all houses are heated with geothermal. This transition improved quality of life and saved over 4% of GDP in 2020, with no heating cost spikes during the Ukraine war.
At Geoscience Australia, Anthony explained that ground source heat pump systems were best suited to climates with hot summers and cold winters. Zhenjun said much of Australia simply did not get cold enough to make the systems efficient.
The reasons are clear: it's too expensive, takes too long, and comes with unnecessary risks. Instead of gambling on nuclear, Australia needs to get on with the job of building clean, affordable, and proven renewable energy solutions. The future is renewable — not radioactive.
All waste is meticulously sorted by radioactivity level and by type. Whenever possible, the waste is subsequently treated using various processes: compaction, incineration, melting or vitrification.
5 The underlying principle here is that all matter caught in the sun's gravity will lose its structural integrity due to the stress of gravitational forces and “break up” before reaching the sun. Moreover, high temperatures will incinerate and completely consume all matter prior to its reaching the sun's corona.
The Tsar Bomba (code name: Ivan or Vanya, internal designation "AN602") was the most powerful nuclear weapon or weapon of any kind ever constructed and tested. A project of the Soviet Union, it was a thermonuclear aerial bomb, tested on 30 October 1961 at the Novaya Zemlya site in the country's far north.
Who has the most nuclear weapons? Russia has the most confirmed nuclear weapons, with over 5,500 nuclear warheads. The United States follows behind with 5,044 nuclear weapons, hosted in the US and 5 other nations: Turkey, Italy, Belgium, Germany and the Netherlands.
Government policy, set under a former administration in 2014, aimed to reduce nuclear's share of electricity generation to 50% by 2025. This target was delayed in 2019 to 2035, before being abandoned in 2023. In February 2022 France announced plans to build six new reactors and to consider building a further eight.
All U.S. nuclear power plants store spent nuclear fuel in "spent fuel pools." These pools are made of reinforced concrete several feet thick, with steel liners. The water is typically about 40 feet deep and serves both to shield the radiation and cool the rods.
Most nuclear power plants have operating life- times of between 20 and 40 years.
