French nuclear company Framatome said on 9 October that, together with US company Lockheed Martin it had completed the installation and site acceptance testing of a new Engineered Safety Features Actuation System (ESFAS) replacement for unit 2 of Exelon Generation’s Calvert Cliffs nuclear plant.

The work was completed during the plant’s spring 2019 refuelling outage.

The new ESFAS boasts triple modular redundancy and allows plant operators to control and manage reactor operations to ensure efficient and reliable power generation, Framatome said.

The contract to develop the customised analogue system was awarded in 2017 to Framatome in collaboration with  Lockheed Martin’s Energy line of business.

Calvert Cliffs in Maryland comprises two pressurised water reactors with capcity of 1850MWe.
