For more than 45 years, L3 MAPPS (subsidiary of L3Harris Technologies) has worked with leading utilities, plant designers and research organizations to create superior training simulator and engineering-assist simulators and has established itself as the world’s pre-eminent manufacturer of power plant simulators for CANDU, PWR, BWR and gas-cooled reactors. L3 MAPPS has vast experience in supporting New Build projects with its simulation solutions—resulting in significant error reduction in the plant designs.

In 2019, L3 MAPPS introduced disruptive display technology–Orchid® IX–bringing 3D visualization solutions to life without VR headsets!

L3 MAPPS also develops and delivers Digital Control Computer (DCC) systems to CANDU plants. In addition, the company supports CANDU operators with custom-designed hardware solutions to replace existing I&C systems that are no longer supported by the original vendors.

L3 MAPPS’ Power Systems and Simulation business got its start in the early 1970s developing its first DCC equipment for Bruce A and its first simulator for Pickering A. Today, L3 MAPPS supplies products and services to leading utilities worldwide.
