Leningrad unit 3 gets approval to operate to 2030
Russia's nuclear regulator Rostakhnadzor has issued a licence for Leningrad nuclear power plant's third unit to operate for a further five years, to 2030.
The RBMK-1000 unit, which entered commercial service in 1980, has generated more than 290 billion kWh of electricity, and had already had its original 30-year operating life extended by 15 years.
Rosenergoatom said that the licence was issued after a comprehensive analysis of the condition of equipment and documentation to ensure the unit's compliance with modern safety and reliability requirements, as well as the implementation of measures to modernise equipment where necessary.
It said that the assessment concluded that it would be safe to extend operation to 50 years.
Director of the Leningrad NPP Vladimir Pereguda, said: "Work to extend the lifetime of existing power units of Russian nuclear power plants has been carried out since 1998. Our units are no exception. An additional period of operation is not only about generating electricity. These are jobs, and the continuation of the production of unique isotope products, and systematic work on the construction and commissioning of two more new VVER-1200 units."
The operator is also in the process of seeking a licence for the operation of Leningrad unit 4 to 2030. Elsewhere in Russia, work is taking place to extend the lifetimes of Kursk 3 and 4, Smolensk 1, 2 and 3 and Kalinin unit 1.
The Leningrad plant is one of the largest in Russia, with an installed capacity of 4400 MWe, and provides more than 55% of the electricity demand of St Petersburg and the Leningrad region, or 30% of all the electricity in northwest Russia.
Leningrad units 1 and 2 - both 1000 MWe RBMK units - shut down in 2018 and 2020, respectively. As the first two of the plant's four RBMK-1000 units shut down, new VVER-1200 units started at the neighbouring Leningrad II plant. The 60-year service life of these fifth and sixth units (also known as Leningrad II-1 and Leningrad II-2) secures power supply until the 2080s. Units 7 and 8 - scheduled to be commissioned in 2030 and 2032 respectively - will replace units 3 and 4 as they are shut.
