Unit 2 of Kola NPP begins 30-day scheduled preventive maintenance

On August 2, 2026, Unit 2 of the Kola Nuclear Power Plant launched scheduled preventive maintenance (SPM) incorporating modernization elements, expected to last approximately 30 days. During this mid-cycle overhaul, specialists will carry out extensive work on critical equipment. In the reactor shop, major repairs will be performed on part of the steam generators, main circulation pumps, and primary circuit piping. Plans also include disassembly and reassembly of the reactor plant, nuclear fuel replacement, and repair of the reactor internals and safety system equipment.

In the turbine shop, turbine units, turbogenerators, circulation pumps, low-pressure heaters, and separators-superheaters will be repaired. On the electrical side, transformers and diesel generators will undergo maintenance. Additionally, upgrades are planned for the automatic chemical control system of the primary coolant and the DC power distribution panels for the entire station and individual units.

Vladimir Matveyev, Chief Engineer of the Kola NPP, stated: "Scheduled preventive maintenance helps maintain a high level of safety and operational reliability. We carry out all technical measures with the utmost responsibility: every work stage is aimed at ensuring the stable and efficient operation of the plant, thereby providing uninterrupted power supply to our region."

As Alexey Likhachev, head of Rosatom, previously emphasized, the company and its enterprises consistently adhere to the principles of transparency, responsibility, and safety in their operations. Currently, three units of the nuclear power plant are in operation with a total load of 1012 MW. The radiation background level in the area of the Kola NPP is 0.07 µSv/h, which corresponds to natural background values.
