description: This work is devoted to the calculation of the passive part of the VVER-1200 reactor for the El-Dabaa NPP project. Tasks that were solved during the research: 1 1. Study and justification of the layout of the reactor building of the El-Dabaa NPP; 2. Study and justification of safety systems for maintaining the coolant supply at low pressure of the primary circuit; 3. Calculation of the passive part of the emergency protection system of the core; 4. Construction of a modified layout of the reactor building. This paper presents a method for calculating the passive part of the emergency cooling system of a nuclear reactor core. The change in the characteristics of the reactor circuit in the event of an accident with a large leak is considered and analyzed. The possibility of changing the layout of the reactor building of the El-Dabaa NPP project is analyzed.
