description: This work is devoted to the calculation of the parameters of the boron control system for nuclear power plants with a VVER-500 type reactor, such as the concentration of boric acid for different stages of the reactor campaign and the time before it is reached, the volume of the systems tanks, the pressure and flow rate of the system pump, and others. The considered tasks can be listed as follows: 1. Selection and justification of the boron control system for VVER-500. 2. Implementation of thermal calculation of the reactor core. 3. Implementation of the neutron-physical calculation of the reactor core. 4. Calculation of the parameters of the boron control system and analysis of its effectiveness for various operating modes of the reactor plant. As a result of the work, the concentration of boric acid required for starting the reactor was determined, as well as the time to achieve it, taking into account the characteristics of the pump system that meet safety requirements. The decrease in the concentration of boric acid during the reactor campaign was calculated and analyzed, as well as the time to achieve the required concentration in emergency situations.
