Hungarian Atomic Energy Authority has issued the license for groundwater cut-off construction for the Paks II NPP project. Groundwater cut-off will protect the construction site as well as operating Paks NPP from groundwater penetration. Following the construction of the groundwater cut-off, excavation works on the Paks II site will commence. Currently, HAEA is reviewing construction license application needed for these works to begin.Preparations are already underway for soil stabilization and the construction of diaphragm walls at the construction site while the construction base is being prepared. Some 120 buildings and structures will be built, including workshops, warehouses, parking lots and roads.Paks II NPP is built based on the Russian-Hungarian intergovernmental agreement signed on January 14 2014 by the general contractor ASE EC JSC, a subsidiary of ROSATOM. The project envisages two VVER-1200 PWR units being implemented within the framework of international cooperation.
