A sample of thorium. Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium.A thorium fuel cycle can offer several potential advantages over a uranium fuel cycle [Note 1] —including the much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced ...
Anti-nuclear power protests preceded the shutdown of the Shoreham, Yankee Rowe, Millstone I, Rancho Seco, Maine Yankee, and about a dozen other nuclear power plants. [155] On 12 June 1982, one million people demonstrated in New York City's Central Park against nuclear weapons and for an end to the cold war arms race.
The most common fuel used in conventional nuclear fission power stations, uranium-235 is "non-renewable" according to the Energy Information Administration, the organization however is silent on the recycled MOX fuel. [3] The National Renewable Energy Laboratory does not mention nuclear power in its "energy basics" definition. [4]
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]
As of 2019, nuclear generated over a quarter of all low-carbon energy, making it the second largest source after hydropower. [89] Nuclear power's lifecycle greenhouse gas emissions—including the mining and processing of uranium—are similar to the emissions from renewable energy sources. [84] Nuclear power uses little land per unit of energy ...
Stewart Brand at a 2010 debate, "Does the world need nuclear energy?" [31]At the 1963 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 ...
The stable salt reactor (SSR) is a nuclear reactor design proposed by Moltex Energy. [118] It represents a breakthrough in molten salt reactor technology, with the potential to make nuclear power safer, cheaper and cleaner. The modular nature of the design, including reactor core and non-nuclear buildings, allows rapid deployment on a large scale.
Nuclear power's contribution to global energy production was about 4% in 2023. This is a little more than wind power, which provided 3.5% of global energy in 2023. [167] Nuclear power's share of global electricity production has fallen from 16.5% in 1997, in large part because the economics of nuclear power have become more difficult. [168]
