L3 MAPPS to Supply Three Digital Control Computers to Bruce Power

L3 MAPPS has confirmed that it has signed a deal with Bruce Power to supply three digital control computers (DCCs), which will replace the current Bruce A Unit 2 system with all-new hardware.

The first unit (DCC-Z) will be used as a maintenance platform and is due to be installed towards the end of 2019. The other two DCCs (DCC-X and DCC-Y) 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. The 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.

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

L3 MAPPS president Rangesh Kasturi added: “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.”

Bruce Power president and CEO Mike Rencheck said: “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.

“Our multi-year life-extension programme 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.”
