The concreting of the foundation slab—which serves as the foundation for the five buildings of the Unit 5 nuclear island and has an average thickness of three meters—is being carried out in bays. During the latest construction phase in the second week of September, work proceeded without interruptions for 30 hours. In an operation involving two shifts and 180 specialists, 2,010 cubic meters of C35/45 strength-class basalt concrete were poured into the foundation slab using twenty mixer trucks. The concreting was preceded by the installation of 670 tons of reinforcing steel.

In the bayed excavation pit of Unit 5 the following work processes are taking place in parallel: the placement of levelling concrete, installation of waterproofing and grounding mesh on  the levelling concrete, and the reinforcement installation.  At the end of each phase bays of the foundation slab of the  nuclear island is poured using special concrete. During the most recent phase approximately 1,500 cubic meters of concrete were poured into the foundation slab.

While a comprehensive review of the project is still underway, construction activities continue with a focus on business continuity. This includes, among other things, the building of the Construction and Erection Base, the construction of the Training Centre, and the excavation of the Unit 6 excavation pit to the design level—a task that is more than 90 percent complete.The first tower crane has also been erected on the northern side of the excavation pit of Unit 5. The crane, with a 64-meter hook height and lifting capacity of 350 tons is the first in a series of dozens of such lifting machines. The cranes and lifting machines required for the construction of the Paks II Nuclear Power Plant are being installed according to schedule.
