Eptisa will carry out a geotechnical, geophysical and hydrogeological exploration campaign for the construction of the nuclear Centralized Temporary Storage facility in Villar de Cañas, Cuenca region

These studies will allow ENRESA to establish the parameters values to use for the construction of the facility

ENRESA (National Radioactive Waste Company) has awarded a new contract to the joint venture formed by Eptisa, AGS & Sondeos Peñarroya to carry out a dynamic geotechnical characterization study to determine the soil-structure interaction and a complementary hydrogeological analysis at the nuclear Centralized Temporary Storage facility (CTS) of Villar de Cañas in Cuenca.

Eptisa participated in the previous phases of the project and realized preliminary geological studies to obtain the geological, geomorphological and neotectonic information necessary to determine the characteristics of the materials on the site surface and subsurface, and a specific study in the immediate vicinity of the site where the CTS Villar de Cañas will be built.

The new project involves conducting a geotechnical and geophysical exploration campaign, in accordance with the American nuclear standards. It will reach greater depths than the ones investigated so far (up to 200 meters) to establish a dynamic geotechnical characterization of the soil which will serve as a basis for soil-structure interaction analysis and to adequately model the foundations of the nuclear CTS facility.

Additionally, static geotechnical parameters will be obtained in some of the surveys to establish a comparison with those obtained in previous exploration campaigns and correlate them with the acquired dynamic geotechnical parameters.

New hydrogeological studies will be carried out in line with the corresponding lithological, geophysical and hydraulic researches to improve the existing conceptual model for the hydrogeological System of the nuclear CTS facility.

In addition, the joint venture will perform additional work to establish the electrical resistivity of the soil for the design of the grounding networks in the direct vicinity of the electrical substation, seal of boreholes from previous exploration campaigns or drilled for the present surveys, and determine the ground’s temperature and thermal conductivity of the.

The work, with the exception of several new hydrogeological surveys, will be carried out within the plot of land called "Las Balance-Los Boleos" with an area of ​​approximately 53 hectares. More specifically, the studies will focus on the protected area of the nuclear installation, covering an area of ​​approximately 30 hectares.
