L3 MAPPS Wins Digital Control Computer System Hardware Replacement for Bruce Unit 2

Bruce Nuclear Generating Station, the largest nuclear facility in the world with eight operating reactors totaling 6,384 MW, will replace some of its control systems as part of a series of life-extension investments.

L3 MAPPS has won a contract from Bruce Power to deliver three Digital Control Computers, replacing the existing Bruce A Unit 2 system with all-new hardware.

The first unit will be used as a maintenance platform and is due to be installed in the fall of 2019. The other two DCCs are redundant units for plant operations and are expected to be delivered in the first quarter of 2020.

DCC systems are used to monitor and control the major reactor and power plant functions at CANDU nuclear power plants. L3 MAPPS’ new DCC system will feature the latest SSCI-890 CPUs and will replace the legacy Varian V72 computer systems and related equipment to ensure continuous, safe and reliable performance over the service life of the plant.

“Thanks to the Bruce Life-Extension Program and other CANDU refurbishment programs, we are seeing increased activity in our power controls business,” said Michael Chatlani, vice president of marketing and sales for L3 MAPPS Power Systems and Simulation.

“As the Life-Extension Program progresses, we are well-positioned to assist Bruce Power with its six remaining DCC replacements and other I&C replacement projects,” said Rangesh Kasturi, president of L3 MAPPS.

“As Bruce Power continues on its quest to ensure that Ontario is provided with clean, reliable and low-cost nuclear power for decades to come, it is key that reliable suppliers like L3 MAPPS are engaged in our projects,” said Mike Rencheck, President and CEO of Bruce Power. “Our multi-year life-extension program that began in January 2016, and is Canada’s largest infrastructure project, remains on time and on budget, and we look forward to the Bruce site powering the province until 2064.”
