A ceremony dedicated to the start of the construction of the fourth unit at the first nuclear power plant in Turkey was held at the Akkuyu NPP site, signifying the beginning of the main construction phase. The licence for the construction of the fourth power unit of the Akkuyu NPP was issued by the Turkish Nuclear Regulatory Agency in October 2021. The concreting was preceded by a wide range of preparatory work which included dewatering, excavation of a basement pit, installation of a concrete cushion and waterproofing, reinforcement of the basement and installation of embedded parts. The specialists pour concrete in the base of the future power unit and reinforce it with armature. The basement is divided into 16 zones, the so-called "captures". The height of the concreting will be 2.6 metres, the average volume of each zone will be 1100 cubic metres, 17,000 cubic metres of concrete mix in total will be laid down in the basement of the unit.The concreting process is carried out under the control of the laboratory specialists of the concrete plant, representatives of AKKUYU NUCLEAR JSC, the main construction contractor, the joint venture TITAN 2 IJ ICHTASH INSHAAT and independent construction control organisations.Construction work continues in all areas of the project. Concreting of the foundation plates of the reactor building and turbine building in Unit 1 has been completed, the core catcher, reactor pressure vessel, steam generators, main circulation pump units have been installed, the welding of the main circulation pipeline has been completed. The fifth layer of the inner containment vessel was installed. The 6th layer of the inner containment vessel, which is the lower part of the dome, is mounted and the pole crane is pre-assembled. A core catcher has been installed in Unit 2, the concreting of the foundation plates of the reactor building and the turbine building has been completed, and the third layer of the inner containment vessel has been installed. In Unit 3, while the reinforcement of the foundation floors of the reactor building and turbine building was completed, concrete was poured on the foundation of the turbine building and reactor building, and a core catcher was installed.
