Russia's Leningrad NPP resumes hot water supply to Sosnovy Bor

On August 31, 2026, Russia's Leningrad NPP resumed hot water supply to the city of Sosnovy Bor via the district heating station (BRT) after completing scheduled maintenance.

Dmitry Tsygankov, workshop manager of the turbine department at Leningrad NPP, stated that the plant had successfully completed BRT-related maintenance work in August, including chemical cleaning of heat exchange equipment, overhaul of pumping equipment, industrial safety assessments, and the necessary hydraulic pressure tests of pipelines. He said that the BRT is now supplying hot water to the city and industrial zone as planned, and the plant is preparing for the scheduled start of the Sosnovy Bor heating system; the heating system will be put into operation once outdoor temperatures drop to the appropriate level.

During the BRT maintenance period, hot water supply to the city of Sosnovy Bor was provided by municipal boiler houses.

Sosnovy Bor is a satellite city of Leningrad NPP, where the local heating season typically begins in late September or early October after outdoor temperatures drop. The heating system will be started in a set sequence, with city social institutions connected first, followed by the industrial zone, which includes 14 enterprises under Russia's Rosatom.

Currently, both the RBMK-type and VVER-type reactors at Leningrad NPP can serve as heat sources for the BRT system. The system can supply approximately 850,000 Gcal of heat annually, meeting the heating needs of organizations and enterprises in the industrial zone, as well as residential areas and neighborhoods in Sosnovy Bor.
