The Argentinian National Commission of Atomic Energy (CNEA) developed the RA-10 project, an experimental multipurpose nuclear reactor with a power of 30 MW, located in the Ezeiza Atomic Center, in Buenos Aires, Argentina. The foundation of the reactor is a reinforced concrete mat placed on a sedimentary pile including Pleistocene indurated fine soils and deep Miocene clays. The paper presents various aspects of the design of this foundation, including the calibration of numerical models for the 3D ground-structure interaction analysis and the structural optimization of the mat in terms of stresses, deformations and interaction among adjacent buildings.
