For more than 45 years, L3 MAPPS 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.
