At the Leningrad NPP-2, the installation of the extremely important equipment for the power unit No. 2 has begun: the diesel generator of reliable power supply of normal running was installed at a proper location in the diesel power plant building.

After fixing on the foundation and pouring the foundation with concrete, the equipment will be tied with pipelines of various systems - cooling, air supply, gas outlet, oil and fuel supply, and others. At the next stage, the experts will start-up the diesel generator; they will check the correctness of the electrical connections, will connect this generator to the mains and will conduct the necessary tests.

Four more diesel generators of the emergency power supply system will be placed in the building of a standby diesel power plant. The works will be performed in the second quarter of 2019, immediately after the completion of the foundations for this equipment.

Diesel generator set is equipment that improves safety of a nuclear power plant. In case of an emergency situation (shutdown of an external power source), they will provide with power supply all the main and auxiliary processing equipment of the power unit for putting the reactor plant equipment into a safe state.

According to Alexander Rudnik, Deputy Electrical Chief Engineer of the Leningrad NPP-2 the entire set of diesel generators should be ready for use this autumn.

“In the 4th quarter, large-scale testing of the main processing systems including cold and hot functional tests will begin at the power unit. These works will require significant power consumption. First of all, in order to ensure the functioning of the main circulating pumps which flush the primary coolant. In case of power loss, diesel generators will almost immediately be put into operation and will create the necessary conditions for the proper conducting of all scheduled tests”, - Alexander Rudnik explained.
