Framatome and Lockheed Martin successfully completed the installation and site acceptance testing of a new Engineered Safety Features Actuation System (ESFAS) replacement for Exelon Generation’s Calvert Cliffs Nuclear Power Plant, Unit 2, during the plant’s spring 2019 refueling 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. The contract to develop the customized analog system was awarded in 2017 to Framatome in collaboration with global security and aerospace company Lockheed Martin’s Energy line of business.
“Framatome’s instrumentation and control systems are key technological bricks that can adapt to our customers’ needs for the ever safer operation of their nuclear plants. We embrace the positive potential of collaboration in projects where conditions are favorable, and the ESFAS for Calvert Cliffs is a perfect example of that,” said Frédéric Lelièvre, senior executive vice president in charge of Sales, Regional Platforms and the Instrumentation and Control Business Unit at Framatome. “The teamwork displayed by Framatome, Lockheed Martin and the Calvert Cliffs site staff at Unit 2 was exemplary, and it played a significant role in the success of this project.”
“Lockheed Martin is proud to partner with Framatome on the Calvert Cliffs modernization project. Our integrated safety Instrumentation and Controls systems provide a cost-effective and low-risk solution to realize modernization projects like this one,” said Dan Norton, Vice President of Lockheed Martin Energy.
Calvert Cliffs Nuclear Power Plant is located in Calvert County, Maryland. Its two pressurized water reactors produce 1,850 megawatts of energy, enough electricity to power more than one million homes.
