Nuclear Power Plant Vandellòs II

The Vandellòs II power plant, located on the Mediterranean coast, must be inspected every five years to ensure that its containment building complies with regulations. Following the regulatory assessment, the operator ANAV entrusted VSL with inspecting the prestressing system.

The teams followed the procedures defined by the client: verification of the cables by controlled lifting, partial opening of the tendons, grease sampling, corrosion analysis, and re-tensioning after inspection.

Before working on site, VSL calibrated the instruments, tested the equipment, and provided the necessary training to work in a nuclear zone.

On site, inspections focused on the concrete, sheaths, and cables. The selected tendons were checked and then retensioned once the analyses had been carried out. The work carried out reinforces the safety of a structure that is essential to the region's power supply.
