Nuclear fuel - Wikipedia
网页Nuclear fuel is material used in nuclear power stations to produce heat to power turbines. Heat is created when nuclear fuel undergoes nuclear fission. Nuclear fuel has the highest energy density of all practical fuel sources.
What is Nuclear Energy? The Science of Nuclear Power
网页2021年8月2日 · Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission – when nuclei of atoms split into several parts – or fusion – when nuclei fuse together. The nuclear energy harnessed around the world today to produce electricity is ...
Nuclear Fuel Cycle - Department of Energy
网页2016年11月15日 · The nuclear fuel cycle is made up of two phases: the front end and the back end. The front end prepares uranium for use in nuclear reactors. These steps include mining, milling, conversion, enrichment, and fuel fabrication. The back end ensures that the used nuclear fuel is safely managed, recycled, or disposed of.
The nuclear fuel cycle - U.S. Energy Information Administration (EIA)
网页2023年10月26日 · The nuclear fuel cycle consists of two phases: the front end and the back end. Front-end steps prepare uranium for use in nuclear reactors. Back-end steps ensure that used—or spent—but still highly radioactive, nuclear fuel is safely managed, prepared, and disposed of.
Nuclear energy | Definition, Sources, Uses, & Facts | Britannica
网页2024年8月13日 · Nuclear energy, energy that is released in significant amounts in processes that affect atomic nuclei, the dense cores of atoms. One method of releasing nuclear energy is by controlled nuclear fission, used in nuclear power plants around the world. Another method, controlled nuclear fusion, has not yet been perfected.
Nuclear Energy - Our World in Data
网页Nuclear energy and renewable technologies typically emit very little CO 2 per unit of energy production and are also much better than fossil fuels at limiting local air pollution. However, while some countries invest heavily in increasing their nuclear energy supply, others are shutting down their plants.
The Future of the Nuclear Fuel Cycle | MIT Energy Initiative
网页The implications on the world energy system, beyond short-term price increases from greater use of oil and liquefied natural gas, are yet unknown and go beyond nuclear energy. From a technical perspective, there will be the lessons learned such as higher tsunami walls and the need for vented reactor containments that do not require emergency ...
Nuclear fuel qualification: History, current state, and future
网页The qualification of nuclear fuel is the process by which a fuel is certified for use within a reactor design. This process involves massive technical and procedural coordination across multiple private and public institutions with long project completion timelines. The current frameworks published in literature do not address the roles of ...
网页The nuclear fuel cycle is an industrial process involving various activities to produce electricity from uranium in nuclear power reactors. The cycle starts with the mining of uranium and ends with the disposal of spent fuel and other radioactive waste. The raw material for today’s nuclear fuel is uranium.
What are the fuel cycle challenges of tripling nuclear capacity?
网页6 天之前 · More than 120 nuclear energy and technology companies and 25 countries have signed up to the pledge to aim to at least triple global nuclear energy capacity by 2050. One key question is how fuel supplies will be able to expand if such a goal is to be achieved. Here are extracts of what key sector figures said during a discussion on the subject.
