IAEA INITIATIVE ON OPEN-SOURCE NUCLEAR CODES FOR REACTOR ANALYSIS

The International Atomic Energy Agency (IAEA) aims to support and strengthen its Member States' capabilities in the field of advanced reactors' modelling and simulation. Several years of work have been performed by many institutions on the creation of modern open-source tools for reactor analysis and the trend towards open-source codes and open-access data is evident in the scientific community. In 2021, the IAEA initiated activities to support, coordinate, and create synergies in the development of open-source nuclear codes for reactor analysis. As an outcome of this initiative, the IAEA has already established a platform available to all IAEA Member States: The Open-source Nuclear Codes for Reactor Analysis (ONCORE). This platform is attractive for developers around the world, who are seeking collaboration in the area and for exploring new nuclear codes for research and development as well as education and training activities. This paper highlights the recent activities organized by the IAEA within the framework of the ONCORE initiative.
