Reconstruction of the VVO System (Early Warning System) in the ZHP (Emergency Preparedness Zone) of the Dukovany NPP

I&C Energo a.s. has won the contract - Reconstruction of the VVO system (Early Warning of the population System) in the ZHP (Emergency Preparedness Zone) of the Dukovany NPP by ČEZ, a.s. By implementing this contract, we will again expand the scope of activities in the company's professional portfolio.

The purpose of the work is to ensure reliable warning of the population in the event of an emergency in the ZHP (Emergency Preparedness Zone) of the Dukovany NPP, which is a 20 km radius from the plant. The existing rotating sirens without backup power supply or the possibility of providing verbal information and back diagnostics of functionality will be supplemented and replaced with modern electronic sirens meeting the current technical requirements of the Fire Rescue Service of the Czech Republic. The new sirens will fulfil all the functions that the existing ones lack, including the connection of the new terminal elements (KP) to the unified warning and notification system and the transmission of back diagnostics. The electronic sirens will be supplied by WARNING SYSTEMS s.r.o. and Telegrafia a.s.

The reconstruction affects a total of 275 terminal elements (KP) in 139 ZHP locations of the Dukovany NPP. In 212 cases, the outdated rotating sirens will be replaced with new ones, and in locations with insufficient coverage, another 38 completely new terminal elements (KP) will be installed. In 108 cases, the new sirens will be placed on a stand-alone mast, mainly to avoid complications with entering the buildings on which the sirens are located. The requirement to locate the new masts on municipally or state owned land or property must be met.

The documentation phase will take almost a year, during which negotiations with authorities and institutions will take place, including the establishment of easements with property owners, project documentation will be prepared in detail for the planning procedure (DÚŘ) and construction procedure (PDSŘ), then the project documentation (PD) for the implementation of the construction (PDPS), separately for each location. This will be followed by the documentation for implementation and the actual implementation of the individual sub-units in the predetermined locations with a final completion date of 31 December 2027.

The action will be demanding both administratively and in terms of implementation, but above all, it will be necessary to coordinate all activities and subcontracts so that the individual activities follow smoothly and the Work can be successfully completed within the set deadlines. We see this as a major challenge.
