Introduction

Nuclear Energy Statistics: As the world strives to shift its energy paradigm away from fossil fuels to lower-carbon energy sources, There is a wide range of renewable energy sources and technologies, such as hydropower, wind power, solar power, and nuclear power. Renewable and nuclear energy technologies generally produce the least amount of carbon dioxide per quantity of electricity produced.

Nuclear energy is far superior to fossil fuels when it comes to reducing pollution in the local area. Although certain countries are investing heavily in the development of their nuclear energy sources, others have taken their nuclear plants off the grid. The role nuclei play in the energy system, therefore, is more specific to particular nations. Let's look into Nuclear Energy Statistics.

Data on uranium and nuclear fuel, nuclear power plants and reactors, radioactive waste, and nuclear power generation. International data on nuclear generation also available. Monthly, quarterly, and annual data available.

Nuclear energy consumption in the United States amounted to some *****exajoules in 2024, up from over an annual consumption of over ****exajoules recorded in 2022 and 2023. Between 1998 and 2024, consumption of nuclear energy in the North American country increased by *** exajoules, peaking at *****exajoules in 2019.The United States accounts for almost ********* of the worldwide nuclear energy consumption.

The United States is the largest consumer of nuclear power, accounting for almost 30 percent of the world’s nuclear power consumption in 2024. In 2023, nuclear energy consumption in the U.S. totaled 7.3 exajoules. Nuclear power generation In 2010, global nuclear power generation reached 2,630 terawatt-hours. Following the Fukushima nuclear disaster in March 2011, that year saw an output drop. Generation also declined in 2012 but has since recovered, peaking at 2,657 terawatt-hours in 2019. Currently, nuclear power accounts for roughly nine percent of global electricity generation. Nuclear reactors As the top producer of nuclear power, it comes as no surprise that the U.S. has by far the most operable nuclear reactors worldwide. With a total of 94 units in operation as of May 2025, this is almost 40 more than in China. Nevertheless, whilst the U.S. had no planned nuclear reactor additions at the time, China had 41. The Asian country also had 28 nuclear reactors under construction. It is projected that China will surpass the U.S. as the world’s largest nuclear energy producer.

The state of Illinois is the leading producer of nuclear energy in the United States. In 2024, this state generated over 99 terawatt-hours of nuclear energy. Illinois is also the state with the largest number of nuclear power reactors in operation in the U.S.. This state of the Northern Midwest had 11 nuclear reactors in 2024, located in six different nuclear power plants. Nuclear energy production in the United States The process of nuclear fission between a neutron and a large uranium atom releases nuclear energy, which is primarily used to produce electricity. Nuclear energy is employed to heat water, creating steam that, in turn, powers turbines linked to electricity generators. This type of energy has accounted for no less than 18 percent of U.S. annual electricity generation in the last three decades. U.S. nuclear power reactors in operation  Although the operable nuclear power reactors in the U.S. have seen a downward trend since 1990, nowadays, the country still holds 94 operable units. With this quantity of operating reactors, the North American nation is the leader in nuclear electricity production worldwide.

The Population Exposure Estimates in Proximity to Nuclear Power Plants, Locations data set combines information from a global data set developed by Declan Butler of Nature News and the Power Reactor Information System (PRIS), an up-to-date database of nuclear reactors maintained by the International Atomic Energy Agency (IAEA). The locations of nuclear reactors around the world are represented as point features associated with reactor specification and performance history attributes as of March 2012.

The Office of Nuclear Energy's (NE) primary mission is to advance nuclear power as a resource capable of making major contributions in meeting our Nation’s energy supply, environmental, and energy security needs. We seek to resolve technical, cost, safety, security and regulatory issues through research, development and demonstration. By focusing on the development of advanced nuclear technologies, NE supports the Administration’s goals of providing domestic sources of secure energy, reducing greenhouse gases, and enhancing national security. NE’s program is guided by the four research objectives detailed in its Nuclear Energy Research and Development Roadmap: Develop technologies and other solutions that can improve the reliability, sustain the safety, and extend the life of current reactors. Develop improvements in the affordability of new reactors to enable nuclear energy to help meet the Administration’s energy security and climate change goals. Develop sustainable fuel cycles. Understand and minimize the risks of nuclear proliferation and terrorism. NE serves present and future U.S. energy needs by developing critical technologies for the future and helping to train tomorrow’s workforce. The benefits of nuclear power as a safe, carbon-free, reliable and secure source of energy make it an essential element in our Nation’s energy and environmental future.
