A melt localization device, one of the most important elements of the nuclear power plant's safety system, has been successfully delivered to the construction site of power unit No. 4 of the Leningrad NPP-2. The transportation of the unique equipment was organized by Rosenergoatom specialists.

The melt trap, weighing over 730 tons, arrived at the pier in Sosnovy Bor after a 16-day journey spanning approximately 2,000 kilometers. The equipment was transported along the Volga River, Lake Beloye, Lake Onega, and Lake Ladoga, then along the Neva River and across the Gulf of Finland.

The next stage will be the installation of the device into its design position – into the reactor shaft of power unit No. 4, where it will become part of the nuclear power plant's passive safety system.

The melt trap is a unique Russian development designed to operate in extremely unlikely severe accidents. In the event of damage to the reactor core, the system receives molten materials, retains them within a special structure, and ensures effective cooling until complete solidification.

The delivery of the last melt trap signifies the completion of one of the key stages in ensuring the safety of the ongoing construction of power unit No. 4 of the Leningrad NPP-2 and brings the project closer to the next construction phase.
