Abstract
The International Atomic Energy Agency's International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) is to help ensure that nuclear energy is available to contribute to meeting global energy needs of the 21st century in a sustainable manner. The INPRO task titled “Global scenarios” is to develop global and regional nuclear energy scenarios that lead to a global vision of sustainable nuclear energy in the 21st century. Results of multiple studies show that the criteria for developing sustainable nuclear energy cannot be met without innovations in reactor and nuclear fuel cycle technologies. Combining different reactor types and associated fuel chains creates a multiplicity of nuclear energy system arrangements potentially contributing to global sustainability of nuclear energy. In this, cooperation among countries having different policy regarding fuel cycle back end would be essential to bring sustainability benefits from innovations in technology to all interested users. INPRO has developed heterogeneous global model to capture countries’ different policies regarding the back end of the nuclear fuel cycle in regional and global scenarios of nuclear energy evolution and applied in a number of studies performed by participants of the project. This paper will highlight the model and major conclusions obtained in the studies.

The International Atomic Energy Agency’s (IAEA’s) International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) has the objective of helping to ensure that nuclear energy is available to contribute to meeting global energy needs of the 21st century in a sustainable manner
– Natural uranium savings up to 20–40% could be achieved in heterogeneous world with synergistic collaboration among countries (NG1 countries could deploy more fast and less thermal reactors at the expense of U–Pu extracted from spent nuclear fuel of the NG3 or NG3 + NG2 countries), see Figure 4
– The NG1 power demand as well as reprocessing capacity is critical for the fast reactor introduction rate and for the capability of NG1 to reprocess all spent fuel from other NGs, see Figure 5
