Nuclear energy, mysterious and powerful, finds its source in the infinitesimal: the nucleus of atoms. It is released during the fusion of nuclei or during fission, a process that powers our plants. Thanks to this transformation, millions of households benefit from a continuous electricity supply. Reactors, key elements of power plants, transform the heat generated into electricity without relying on fossil fuels, thus contributing to a low-carbon electricity production. Nuclear energy continues to be a pillar in energy production, providing competitive and sustainable solutions to meet the growing global energy needs.
Nuclear energy: Nuclear energy is the binding energy between the constituents of the atomic nucleus. This phenomenon occurs when energy is released from the atomic nucleus, either through fission or fusion. Fission involves the splitting of the nucleus into smaller fragments, thereby releasing enormous amounts of energy. Fusion, on the other hand, results from the combination of two light nuclei to form a heavier nucleus, also generating remarkable energy release.
Nuclear reactors: Nuclear reactors are at the heart of nuclear power plants. Their role is to control and maintain the nuclear fission chain reaction. The heat produced by these reactions is used to generate electricity by converting water into steam that drives the turbines of an alternator. A 900 MW reactor has the capacity to produce an average of 500,000 MWh of electricity per month, sufficient to power approximately 400,000 households.
Fuel cycle: The fuel cycle is the journey taken by nuclear material, from its extraction to its return to the environment. This includes the extraction of uranium, its enrichment, its use in reactors, and the treatment of radioactive waste. Effective management of this cycle is crucial to minimize environmental risks and optimize the use of nuclear resources.
Nuclear safety: Nuclear safety aims to ensure the safe and secure operation of nuclear facilities. The three main safety functions include maintaining the condition of radioactive materials, managing emergency situations, and protecting workers, the public, and the environment. Stringent measures are in place to prevent potential radioactive leaks or incidents.
Nuclear power plant: A nuclear power plant is an industrial facility designed to produce electricity by using the energy released from nuclear reactions. Modern nuclear power plants are equipped with various systems to ensure their safe and efficient operation, such as transformers, alternators, and cooling towers. You can learn more about the funding and management of such facilities here.
Low-carbon electricity: Nuclear energy offers a source of low-carbon electricity, thus contributing to the reduction of CO2 emissions. By producing electricity continuously and competitively, it plays an important role in the energy independence of nations. However, the deployment of nuclear energy is often debated due to safety and waste management issues.
Future of nuclear energy: In the face of growing renewable energy sources, the role of nuclear energy is constantly evolving. Innovations and technological advancements, like those led by experts such as David Faiman, influence the perception and development of nuclear energy. Countries like Japan are strengthening the use of nuclear energy while increasing the share of renewables, and challenges such as the wind power crisis shape global energy discussions.
