Nuclear power plant life cycle

A nuclear power plant must be managed in a safe and efficient manner throughout its entire life cycle, from design through decommissioning, with the overall goal of providing reliable and affordable electricity.

  • Siting of nuclear facilities

    Siting is the term used to describe the process to select where a nuclear installation is built and whether the decided location is suitable for it. Siting is one of the important decisions in the early stage of a planned nuclear energy project. Read more →

  • Severe accident management

    Nuclear power plant safety systems are designed to mitigate a range of abnormal operating conditions. In the unlikely case of a severe accident, plant operators use guidelines developed specifically for the purpose. The IAEA has a toolkit to help operators develop these guidelines and offers training to its Member States. Read more →
