DYWIDAG supports safe containment at nuclear sites worldwide. Our post-tensioning tendons provide continuous reinforcement for containment structures at nuclear power plants. Our monitoring systems support monitoring at nuclear sites worldwide. A crucial early warning system for localized areas, with various sensors connected to DYWIDAG`s cloud-based Infrastructure Intelligence can be used to monitor loads or sense impending movements from fault zones at the face of deep excavations for nuclear reactors—without being affected by temperature changes. The sensors enable engineers to remediate high-stress areas with additional soil nails or anchors before excavations continue. DYNA Force® sensors are being used to monitor loads at the face of some of the deepest excavations for the new reactors. They are the key early warning instrument for localized areas of high stress. The sensors are able to accurately measure any load change, without being affected by temperature changes. The DYNA Force® sensors are being used for load monitoring in conjunction with some of the approx. 14,000 25-40mm Ø GEWI® Soil Nails that are installed to depths of up to 13.5m. The GEWI® Monitoring Soil Nails feature a bonded section of 3m at the distal end of the nail, to point anchor in the stable zone, with the remaining length debonded to allow the nail to be used as a monitor for any load change resulting from movement either side of the slip circle. With the debonded section passing through the active wedge, it is not possible to mobilize any restraining bond in this area; therefore, a heavy bearing plate is required at the face to ensure sufficient restraint.
