ENUSA Industrias Avanzadas S.A. (hereinafter ENUSA) is in charge of the nuclear fuel cycle and carries out environmental services. ENUSA is the parent company of Grupo ENUSA, together with ETSA and EMGRISA.


The nuclear business has as the main and traditional activity the first part of the nuclear fuel cycle, which consists in the following:

  • The management of the supply of enriched uranium for Spanish nuclear power stations.
  • The design, manufacture and supply of fuel to both domestic and foreign nuclear power plants.
  • Engineering services for all regarding the management and optimization of fuel use in the reactor.
  • Fuel services in inspection, repair, fresh and spent fuel handling services, acting in a supportive role for nuclear power stations.
  • The transport of nuclear materials and radioactive goods through our affiliated company ETSA.

As part of the nuclear activities we also develop technological capabilities for the second part of the fuel cycle and the sale of inspection services for fresh and spent fuel.

The environmental business is focused on environmental preservation services and energy production. Through the affiliated company EMGRISA it carries out the treatment and management of all types of waste (industrial, urban, agricultural and stockbreeding waste, agri-business waste), polluted soils and water characterization and treatment, environmental engineering and consulting, and radiological studies.

Besides these activities, our Environmental Unit overviews the restoration of former uranium mining facilities at Saelices el Chico and La Haba with the goal of recovering the affected natural areas in order to try to restore it to its original condition, with environmental and radiological conditions as similar as possible to those prevailing before the start of the mining operations.
