Bulgaria and the US have signed an agreement to cooperate on the development of the Balkan country’s civil nuclear power programme as Sofia is moving forward with plans to build up to two new Westinghouse-made reactor units at the existing Kozloduy site.

The Bulgarian energy ministry said the agreement follows a decision by the country’s parliament in January 2023 to conclude an intergovernmental agreement with the aim of facilitating the construction of nuclear new-build using the US-made AP1000 reactor technology.
