The reinforcement of the Monolith vault continues, while casting of the Active Cells floor slab was performed, including cast-in liner beams. Pipe support has been installed in the Coldbox, where X-ray inspecton of the pipes was performed. Formwork and reinforcement is moving forward in the Sprinkler building, which is now erected to its full 9-metre height. The first wall casting is planned for the end of May.
