Five undisclosed companies have expressed interest in building the proposed Kozloduy-7 AP1000 nuclear plat after a construction tender for the new unit was closed for applicants last week, according to a Bulgarian energy ministry statement 2 February.

Applicants were required to demonstrate experience of construction and commissioning of a minimum of two nuclear units, and similarly a proven track record of contracts for detailed design in nuclear or turbine islands. They also needed to have supplied and installed equipment for such islands within the last fifteen years.
