Market Definition
Nuclear power is produced through the energy released during nuclear fission. In nuclear power plants, electricity is generated by harnessing this process, where heavy atoms such as uranium-235 split when struck by a neutron. This splitting triggers a chain reaction, releasing more neutrons and significant heat. The heat is then used to produce steam, which drives turbines connected to generators, ultimately producing electricity.
The nuclear power market represents the sum of year-on-year installation of nuclear reactor capacities by global companies and electricity generated by nuclear power plants each year, covering the entire plant lifecycle stages. In this study, the sum of the year-on-year cost of decommissioning and maintenance & operation services has been considered.
