Options for the interim storage of IEA-R1 research reactor spent fuels

This paper presents an analysis of different options for the interim storage of research reactor spent fuels. The analysis' results showed a dual-purpose metallic cask as one of the most feasible options for the interim storage of the spent fuels of the IEA-R1 research reactor, located at IPEN-CNEN/SP, in Brazil. In case this reactor keeps its continuous operation at 5 MW in the next years, it will be necessary to transfer the spent fuels, today located in the reactor storage pool, to a spent fuels interim storage, until a definition of the Brazilian national policy on the final disposal of these spent fuels is established.
