Work on standby diesel generators has been completed at unit 2 of Russia’s Leningrad II nuclear power plant. The work was carried jointly by specialists from the Leningrad NPP and equipment manufacturers MAN Energy Solutions France SAS and Moteurs Leroy Somer of France.
The 6.3MW diesel generator sets are each designed for backup power supply to the unit in case of loss of regular power and are an important element of the nuclear power plant safety system. The presence of EDGs is a requirement for all nuclear power plants.
During the final test, the experts simulated a complete blackout of the power unit, turned off the regular power supply for their own needs. Diesel generators were in “standby” mode, within a few seconds started automatically and provided power to all systems and equipment for the subsequent transfer of the reactor installation to a safe state.
Installation of the diesel generator sets took place during the period of widespread coronavirus infection. As a result of negotiations with the French side, in a situation of closed borders and suspended transport links with France, it was possible to arrange the arrival of MAN specialists at the construction site.
“International cooperation in the field of nuclear energy has never been influenced by political or economic circumstances,” said Vladimir Pereguda, director of the Leningrad NPP. “All countries and companies understand that issues of nuclear safety and cooperation in the safe development of nuclear energy are a common task that affects everyone without exception.”
Currently, Leningrad II 2, with a VVER-1200 reactor, is undergoing final preparations for the start of a physical launch. This operation will take place in the summer of 2020. The commissioning of Leningrad II-2 is scheduled for 2021.
