The web page traces the history of nuclear fission from the discovery of radioactivity by Becquerel and the Curies to the Nobel Prize-winning work of Hahn, Meitner, Strassmann and Frisch in 1938. It also explains the mechanism, applications and background of fission, and the role of neutrons, isotopes and elements in the process.
Learn how nuclear power was invented and developed from the discovery of fission to the first nuclear reactors and weapons. The web page covers the origins, the first nuclear reactor, the early years, and the current status of nuclear power.
So from Møller's remark the exciting vision arose that by assembling enough pure uranium (with appropriate care!) one might start a controlled chain reaction and liberate nuclear energy on a scale that really mattered. [22] The news of the discovery of fission was brought to America by Bohr in January 1939. [23]
Chicago Pile-1 (CP-1) was the first human-made self-sustaining nuclear chain reaction, initiated in 1942 by Enrico Fermi and his team at the University of Chicago. CP-1 was a key achievement for the Manhattan Project, the Allied effort to create nuclear weapons during World War II.
Fritz Strassmann was a German chemist who co-discovered nuclear fission with Otto Hahn in 1938. He also helped rescue Jews from the Nazis and received the Enrico Fermi Award in 1966.
Learn how scientists discovered and understood the natural and human-caused causes of climate change since the 19th century. The web page covers the early observations of ice ages, the greenhouse effect, the first quantitative predictions of global warming, and the modern research and assessments.
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei, releasing large amounts of energy and neutrons. Learn about the discovery, mechanism, products, and uses of fission for nuclear power and weapons.
Learn about the use of nuclear reactions to produce electricity, from fission to fusion, and the challenges and benefits of nuclear power. Explore the history, types, issues, and applications of nuclear power plants, fuel cycle, safety, and environmental impact.
