The work is scheduled to begin next month. For this purpose, a temporary power supply for all the systems involved (welding stations, cooling, ventilation) is being installed.

Six 10/0.4 kV substations have been installed at the Power Unit 2 reactor building of LNPP under construction. They will generate power for the entire welding process of the reactor coolant pipelines. To install temporary substations, foundation will be laid and metalwork will be mounted.

These substations were previously used to weld reactor coolant pipelines for the power unit 1 of LNPP under construction.
