The problematic issues of the organization of fire extinguishing process in the engine rooms of nuclear power plants are considered. The need of prompt response to the occurrence of combustion source at the initial stage is substantiated. With the existing methods of ensuring fire safety, it is not always possible to achieve this goal. A conceptual approach is proposed concerning the construction of a system using robotic fire extinguishing installations, the hardware-software control complex of which allows to prevent the development of a fire. This is ensured by monitoring and analysis of the facility state, development of the control commands for the multifunctional fire protection complex.
The innovative system for monitoring fire situation and fire extinguishing was created, which adapts in accordance with the dynamics of the development of a fire and a change in the situation. It is based on the software and digital solutions for ensuring comprehensive full-scale protection of the facilities from fires, accidents, and explosions. The risks to the life and health of the facility personnel and firefighters involved in extinguishing were minimized due to the absence of exposure to hazardous fire factors and their consequences. As a result, an unacceptable economic damage is prevented in case of fires and emergencies at the protected objects.
Proposed complex with separate systems included in it differs from the traditional methods of fire protection. It is fully adapted to the likely scenarios for the development of the situation at the facility. As a result, the fire protection system is formed, which is based not on the general requirements (standards), but on the realistically possible emergency events. This approach not only ensures the efficiency of fire detection and elimination, but also reduces the cost of equipment operation.
