Nuclear power reactors, reactor types and technologies | IAEA
2024年12月13日 · Nuclear power reactors produce energy by initiating and controlling a sustained nuclear chain reaction. Currently, over 400 such reactors in 32 countries provide about 10 per cent of the world’s electricity. The IAEA fosters an international information exchange and collaboration on technological innovations in different reactor technologies.
What are Small Modular Reactors (SMRs)? - International Atomic …
2023年9月13日 · Small – physically a fraction of the size of a conventional nuclear power reactor. Modular – making it possible for systems and components to be factory-assembled and transported as a unit to a location for installation. Reactors – harnessing nuclear fission to generate heat to produce energy. Learn more about nuclear fission and energy.
What is Nuclear Energy? The Science of Nuclear Power
2022年11月15日 · Nuclear power is a low-carbon source of energy, because unlike coal, oil or gas power plants, nuclear power plants practically do not produce CO 2 during their operation. Nuclear reactors generate close to one-third of the world’s carbon free electricity and are crucial in meeting climate change goals.
Water cooled nuclear reactors (WCR) | IAEA
2024年5月9日 · Water Cooled Reactors (WCRs) have been the cornerstone of the nuclear industry in the 20th century. Of the currently operating 442 reactors, 96 per cent are water-cooled. Many of these plants were originally licensed to operate for 40 years, but through advances in knowledge, the lives of these plants are now being extended to 60 years, with a ...
Thorium’s Long-Term Potential in Nuclear Energy: New IAEA Analysis
2023年3月13日 · Comprehensively summarising the results of a four-year IAEA coordinated research project focused on the possibilities of developing thorium-based nuclear energy, the report examines the benefits and the challenges of using thorium as a fuel and analyses its application in different types of reactors — from the most commonly deployed water ...
Large Reactors Poised to Lead the Nuclear Power Expansion as …
The 1970s saw a boom in nuclear power expansion, driven mainly by North America and Europe. In 1970, 15 countries operated 90 nuclear power reactors with a total capacity of 16.5 GW(e). Throughout the 1970s, construction started on 25–30 new nuclear units annually. By 1980, 22 countries operated 253 nuclear power reactors with 135 GW(e) of ...
Small Modular Reactors: Advances in SMR Developments 2024
It also examines the unique global role the IAEA plays in supporting the establishment of sustainable nuclear power programmes and in catalysing technology development and deployment in Member States including through efforts such as the SMR Platform and the Nuclear Harmonization and Standardization Initiative (NHSI).
Exploring Research Reactors and Their Use | IAEA
2020年8月4日 · Research reactors are small nuclear reactors that are primarily used to produce neutrons, unlike nuclear power reactors, which are larger and used to generate electricity. Compared to nuclear power reactors, research reactors have a simpler design, operate at lower temperatures, require far less fuel and, therefore, result in far less waste.
Nuclear Power Reactors in the World - IAEA
It contains summarized information as of the end of 2021 on power reactors operating, under construction and shut down as well as performance data on reactors operating in the IAEA Member States. The information is collected through designated national correspondents in the Member States and the data are used to maintain the IAEA's Power ...
Nuclear installation safety - International Atomic Energy Agency
2016年5月20日 · Nuclear installation safety Regulating and assuring safety is a national responsibility. The IAEA helps Member States meet this responsibility by establishing international safety standards and providing for their application in all types of nuclear installations (power reactors, research reactors and fuel cycle facilities) throughout their ...
