Equipos Nucleares S.A. (ENSA)
Av. Juan Carlos I, 8, Maliaño, 39600, Spain


Since 1973, Ensa is a worldwide leader in the supply of manufactured equipment and services for the civil nuclear industry. Recognized in the nuclear industry for the quality of its products and high-tech manufacturing processes, Ensa is specialized in the manufacture of large components such as reactor vessels, reactor vessel cover heads and internals, steam generators, heat exchangers, casks for fuel storage and transportation, racks for fuel, etc.  The modern equipment and facilities available are able to cope with the largest manufacturing components. Its Advanced Technology Center, with accredited laboratories, creates the opportunity to develop innovative manufacturing techniques and inspections. The staff consists of 455 full time employees with about 110 people in Research & Development.

ENSA Advance Technology Centre, recently renewed, provides the technical support their special manufacturing and examination processes require. Services include fields as Metrology, Calibrations, Metalurgic tests, Metallografic tests, Mechanical tests, Non- destructive examinations, Chemical analysis, Welders and welding procedures qualifications, Material investigations, Robotic and automatizations. Permanent plan of R&D for the latest welding techniques, robotic and control of their processes.
