There are two main classes of fundamental nuclear data, concerned with nuclear structure and decay, and with nuclear reactions. The Nuclear Data Section is responsible for providing accurate and reliable nuclear data for energy and non-energy applications. It assembles, evaluates and recommends specific nuclear data and maintains a number of databases and associated search infrastructure.
The IAEA also provides atomic, molecular and plasma-material interaction data for applications in fusion energy research and technology. Atomic processes are critical for plasma diagnostics in fusion devices and for the energy transport in the plasma. The Section develops, evaluates and disseminates this class of fundamental data.
