Russia’s Rosatom wins contract for Bulgarian NPP modernisation

Rusatom Service, the electric power division of State Atomic Energy Corporation Rosatom, and Bulgaria’s Kozloduy Nuclear Power Plant signed a contract on neutron-flux monitoring equipment modernisation for Units 5 and 6 of the plant, Rosatom said on March 26.
According to Rosatom, this contract was concluded, based on the results of a public tender, which was announced in September, 2019.
Neutron-flux monitoring equipment plays an essential role in ensuring NPP safety and is used in VVER reactor control and protection systems, Rosatom said in a press release.
“Modernisation of this system is a high-priority task. KB Gidropress, the chief designer of Kozloduy NPP reactors, and National Research Center ‘Kurchatov Institute’, the plant’s nuclear research advisor, will be involved in approval of necessary technical documentation,” Rosatom said, adding that Systematom, which has wide experience and references in similar projects, will act as a supplier of the main components of the equipment.
The Rusatom Service project portfolio for Kozloduy NPP in Bulgaria already includes a number of significant tasks, including a completed feasibility study for lifetime extension of the power unit No. 5-6 and modernization of turbogenerators for increased capacity to 104%.
