Leningrad NPP-2: the first diesel generator is installed at the power unit No. 2

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. 

The Leningrad NPP is the country’s first plant with RBMK-1000 reactors (uranium-graphite circuit-type reactor running on thermal neutrons). The decision that marked its construction was taken in September 1966 by a resolution of the Central Committee of the Communist Party of the USSR and the Council of Ministers No. 800-252. According to that document, the Leningrad NPP was supposed to become a core in a network of nuclear power plants with RBMK-1000 reactors that were supposed to produce a substantial share of electric power. The construction of the Leningrad NPP was going well, and by 1973 the first power block was fully erected. On December 23, 1973, following stable 72-hours’ operation at the capacity of 150 megawatt, the State Commission signed the acceptance certificate stating that the first power block of the Leningrad nuclear power plant is commissioned for pilot production.
