Computer simulations play a critical role in understanding physical and chemical systems. In the last decades verification, validation and uncertainty quantification (VVUQ) of computer simulations has become an important research topic in the physical and chemical sciences and engineering. In support of optimization-based design of a fusion reactor and high precision diagnostics of plasmas in fusion devices the IAEA Atomic and Molecular (A+M) Data Unit has been pursuing VVUQ activities for theoretical A+M data. Our objective is to encourage and support the data development community to provide data users with reasonable uncertainty estimates for calculated A+M data and especially for calculated cross sections. After a series of meetings and discussions with theoretical atomic physicists organized by the Unit it has become clear that the VVUQ methods for theoretical data should develop in collaboration with experimental physicists and benchmark experiments.
