Investment project for the extension of the operating life of Leningrad NPP Power Unit 4.

The extension of the service life of operating Leningrad NPP power units has been one of the most labor-intensive and large-scale projects involving the companies of TITAN-2 Group. With its experience in extending the service life of three power units of the Leningrad NPP, in 2008 JSC CONCERN TITAN-2 won the tender for the performance of the full range of works for the modernization, and extension of the service life, of Power Unit 4. As part of a large investment project, TITAN-2 has carried out turnkey works at the plant, including design works, the supply of equipment and commissioning of the facility.

Over 5,000 sets of engineering documentation have been developed within the scope of design and survey works and tens of thousands of pieces of equipment have been supplied for the power unit’s start-up facility. All safety systems of the facility’s power unit and its main and reserve control rooms and standby diesel power plant have been reconstructed, 199 process channels have been replaced, turbines have been rebladed, etc. Power Unit 4 is a second-generation one. It was constructed with due regard to the practice of the construction and operation of the first units and using a new regulatory framework. That is why its modernization has extended its service life for 20 rather than 15 years, i.e. until 2031.
