tailieunhanh - Innovative and safe supply of fuels for reactors

Within the Euratom research and training program 2014–2018, three projects aiming at securing the fuel supply for European power and research reactors have been funded. Those three projects address the potential weaknesses – supplier diversity, provision of enriched fissile material – associated with the furbishing of nuclear fuels. | Innovative and safe supply of fuels for reactors EPJ Nuclear Sci.

Within the Euratom research and training program 2014 2018 three projects aiming at securing the fuel supply for European power and research reactors have been funded. Those three projects address the potential weaknesses supplier diversity provision of enriched fissile material associated with the furbishing of nuclear fuels. First the ESSANUF project now terminated resulted in the design and licensing of a fuel element for VVER-440 nuclear power plant manufactured by Westinghouse. The HERACLES-CP project aimed at preparing the conversion of high performance research reactor to low enriched uranium fuels by exploring fuels based on uranium-molybdenium. Finally the LEU-FOREvER pursues the work initiated in HERACLES-CP completing it by an exploration of the high-density silicide fuels and including the diversification of fuel supplier for soviet designed European medium power research reactor. This paper describes the projects goals structure and their achievements. 1 Introduction With respect to enriched uranium supply global efforts are made to minimize the use of highly enriched At the core of reactor operation nuclear fuel is a uranium in research reactors. In the EU this conversion consumable which necessitates a secure supply chain. In from highly to lower enriched uranium has already begun EU .
