Nuclear supplier and service firm Framatome said this week it had signed a contract to upgrade a component of the instrumentation and control (I&C) system for the two units of Exelon’s Calvert Cliffs nuclear power plant on the western shores of Chesapeake Bay.
The new component, Framatome’s latest digital control element drive control system (DCEDCS), provides simplified maintenance, streamlined system configuration, and overall operational reliability, the company said.
The Calvert Cliffs plant provides more than 80 percent of Maryland’s carbon-free electricity, said Frédéric Lelièvre, senior executive vice president of Sales, Regional Platforms and the I&C Business Unit at Framatome.
Framatome will provide design, fabrication, assembly, documentation, installation and testing for the new DCEDCS at Calvert Cliffs 1&2. The upgrade also includes cybersecurity solutions from Framatome subsidiary FoxGuard Solutions and training simulator upgrades from Framatome subsidiary CORYS.
The DCEDCS, a component of the plant’s overall I&C system, powers the control rod drive mechanisms insert and remove these rods from the reactor those mechanisms. It runs on the Triconex triple modular redundant control platform, providing maximum availability.
The Calvert Cliffs NPP has two pressurized water reactors with a total installed capacity of nearly 1800MWe.
