Belarus has two VVER-1200 reactors, located at Ostrovets, about 120 km northwest of Minsk. These reactors were the first VVER-1200s to be built outside of Russia. Unit 1 was connected to the grid in November 2020 and unit 2 in May 2023.

Before the startup of the reactors, Belarus’s electricity demand was met almost entirely by gas-fired generation, with most of the gas imported from Russia. When both units are fully commissioned, the plant should produce about 18.5 TWh of electricity each year, representing just under half of Belarus’s total electricity requirements, and reducing annual demand for gas by 4.5 billion cubic metres.

In February 2023 the government announced plans to create an organization for radioactive waste management, which would implement a system of long-term storage and disposal of radioactive waste.
