The nuclear fuel cycle ends with the safe, secure and sustainable management of the spent fuel, which includes its storage after withdrawal from the core of the nuclear power plant, followed by either its processing/recycling or final disposal.

The capacity of the Spent Fuel Pools (SFPs) of a large number of NPPs is currently close to saturation and there is not enough space in them to guarantee the long-term operation of the NPP. One of the alternatives to avoid this risk lies in the construction of a temporary Independent Spent Fuel Storage Installation (ISFSI). These installations are based on spent fuel dry confinement systems that guarantee the safety and protection of people and the environment during the time periods prior to long-term management (Central Spent Fuel Storage Facility, CSFSF) or final disposal (reprocessing of spent fuel, Deep Geological Repository, etc) of the fuel.

IDOM provides integral design and engineering solutions for spent fuel dry storage facilities based on different canisters and storage systems technology, these are currently implemented on specific sites in operation. Our approach consists of organizing multidisciplinary qualified teams with the necessary experience, thus incorporating all the expertise of the company to provide integrated management of the work from the safety, quality, economic and technical perspectives in all the stages of the project, from the preliminary studies to the commissioning of the spent fuel storage installation. Our services also cover specialized studies related to spent fuel characterization methodologies.
