The assembly of the facilities for the operational and dispatch management that will serve as a backup in case the major control systems fail has started at the unit control station of the Leningrad NPP’s 2nd power block with a VVER-1200 reactor. The team is expected to install 32 panels, some of which will be placed in the backup control building.

Following the installation, the panels will be welded and connected to the cable lines. Following that, the team will apply the voltage to the equipment and perform the commissioning and start-up activities. The backup system will be tested as a part of the whole automated technology processes management system at the 2nd power block.

According to Anatoliy Chikov, the Deputy Head of the Thermal Automatics and Measurements Workshop at the Leningrad NPP, the main advantage of the panels is their modular structure, which means that the faulty equipment can be easily replaced or, if necessary, upgraded.

It is planned that all works related to this type of equipment is going to be completed in April. This is required to ensure that the liquid release into the technological systems over the open reactor can be performed timely. During this operation, the team will check the penetrability of the reactor facility’s primary system pipe. The liquid release is one of the key tasks for 2019, which is planned for Q2.
