Belarus is committed to the development of nuclear energy in the vicinity of the Lithuanian border

Belarus is committed to the development of nuclear energy in the vicinity of the Lithuanian border

The Belarusian government is determined to build a third unit at the Belarusian Nuclear Power Plant (NPP), in addition to the existing two units. It justifies the construction of Unit 3 on the basis of the country’s allegedly ever-growing electricity demand, emphasising the success of the Belarusian NPP. However, the implementation of this project is not economically viable, given that the current units at the Belarusian NPP are not operating at full capacity.

The Belarusian authorities were also considering the construction of a fourth unit at the Belarusian NPP site or a new nuclear power plant in the Mogilev region. It is possible that Belarus will also see an opportunity to implement these projects.

Russia welcomes and supports Belarus’s plans to develop nuclear energy, which would be implemented by the Russian corporation Rosatom. These plans would deepen Belarus’s energy dependence, which is in line with Russian interests. The Kremlin has expressed support for Belarus’s decision to build a third unit at the Belarusian NPP site and has also urged Minsk not to abandon the plans for building a new nuclear power plant in the Mogilev region. This issue has been a regular topic of discussion at meetings between Rosatom and the Belarusian government.

Despite the plans to develop nuclear energy, the Belarusian authorities are failing to ensure the safe operation of the Belarusian NPP. The plant’s operation is frequently interrupted, and its two units are not operating at full capacity due to various technical issues and staff incompetence. According to international practice, nuclear power plant units are usually shut down every 18–24 months for scheduled inspections and maintenance. However, in 2025 alone, one or both units at the Belarusian NPP were shut down at least three times. Shortcomings in Rosatom’s technologies, particularly those related to reactor cooling systems, also increase the risk of incidents.

The development of nuclear energy in Belarus will pose a risk to Lithuania’s national security interests. It is highly likely that Belarus will fail to ensure the safety of the new facilities. The initiation of the new nuclear projects will also distract attention from incidents at the Belarusian NPP and the technical defects that are causing them. Therefore, the risk of nuclear incidents in Belarus is highly likely to increase.

When announcing the decision to construct a third unit at the Belarusian NPP site in November 2025, Belarusian Deputy Prime Minister Viktor Karankevich also noted that the possibility of building a new nuclear power plant in the Mogilev region was still under consideration.
