The last batch of diesel generators required to facilitate the safety of the second VVER-1200 power block under construction has been delivered to the Leningrad NPP
The Leningrad NPP has received the last batch of extremely important equipment for the second VVER-1200 power block under construction - five diesel generators for the emergency power systems and for the normal operation with a capacity of 6.3 megawatt each.
According to Alexander Rudnik, the deputy chief engineer of the Leningrad NPP-2 who is in charge of the electrical equipment, these diesel generators will be installed at their proper location within the standby and the block diesel power plants. Their installation is due to start mid-Q1 following the completion of the foundation works. The installation and the setting processes will be overseen by the chief engineers of the production company and the Leningrad NPP-2 electrical shop specialists.
Alexander Belyaev, the chief engineer of the Leningrad NPP-2, noted that diesel-driven generators improve the safety level of an atomic plant. In case external power supply is off, they provide electric power to all major and supporting production equipment within a power block to cater for emergency shutdown of a reactor facility.
He also added that the timely installation and setting of the diesel generators will have direct impact on the time lines for the cold and hot functional tests of the 2nd power block’s equipment, which are scheduled for late 2019.
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.
