The Hungarian Atomic Energy Authority issued construction licenses on 30 August 2022 for the reactor building of Unit 5 and for six more buildings on the so-called nuclear island. After obtaining the implementation license, this is another major milestone in the life of the investment, as the license conditions for entering the second phase of the project have been fully met (the company had previously also obtained the manufacturing licenses for core catchers and reactor pressure vessels).
The reactor building is the main building of the Unit and is intended to house the reactor pressure vessel, the main water circuit, the steam generators, the spent fuel pool and the cooling systems for malfunction, as well as the service, auxiliary and control systems. The task of the reactor building with the special double-walled containment design is to ensure that the environment is not adversely affected during nuclear energy production, but its massive design also ensures the protection of technological systems against environmental or man-made hazards.
On the same day, another six buildings around the reactor building, which make up the unit's so-called „nuclear island”, received construction licenses. The service and auxiliary systems of the main technological process of nuclear energy production located in the reactor building, as well as the systems and controllers that ensure the control and safety supervision of the operation, are located in these buildings.
The six buildings:
The buildings have received a safety and earthquake protection classification based on the safety functions of the technology systems in them, and their design accordingly ensures the protection of workers and the environment from the effects of radiation, as well as the protection of their technology systems against environmental and man-made hazards.
