L3 MAPPS to Supply Digital Control Computer System Hardware for Bruce Unit 6, Supporting Life Extension and Continued Low-Cost Nuclear Power


L3 MAPPS announced today that it has won a contract from Bruce Power to replace the existing Bruce B Unit 6 Digital Control Computer (DCC) system with all-new hardware. Three DCCs will be delivered to Bruce Power. The first unit (DCC-Z) will be used as a maintenance platform and is due to be installed in the first quarter of 2018. The other two DCCs (DCC-X and DCC-Y) are redundant units for plant operations and are expected to be delivered in the second quarter of 2019.

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.

"Our first DCC system, built in the early 1970s, was for the Bruce site. With this new project, we have come full circle, marking a new chapter in L3 MAPPS’ DCC business," said Michael Chatlani, Vice President of Marketing & Sales for L3 MAPPS Power Systems and Simulation. "We are happy to continue our long collaboration with Bruce Power. Leveraging our record of on-time, on-budget performance, we look forward to our further support of the Bruce site for many years to come."

"Replacing the DCCs at the Bruce site is an important element of the Life-Extension Program at Bruce Power," said Mike Rencheck, President & CEO of Bruce Power. "Bruce Power’s Life-Extension program will mean the Bruce site will continue to power the province until 2064, and this is good news for families and businesses across Ontario. Bruce Power, and the electricity it provides Ontario families and businesses, is part of the solution over the short and long terms to provide a source of low-cost stable electricity."

Bruce Power is Canada’s first private nuclear generator, providing 30 percent of Ontario’s power at 30 percent below the average residential price. The Bruce site, home to eight CANDU reactors in Tiverton, Ontario, is the world’s largest operating nuclear generating facility. The company is progressing with a series of incremental life-extension investments, including Major Component Replacement, to secure a clean, reliable and low-cost source of electricity for Ontario families and businesses for decades to come.L3 MAPPS has over 30 years of experience in pioneering technological advances in the marine automation field and over 40 years of experience in delivering high-fidelity power plant simulation to leading utilities worldwide. In addition, the company has more than four decades of expertise in supplying plant computer systems for Canadian heavy water reactors. L3 MAPPS also provides targeted controls and simulation solutions to the space sector.
