L-3 MAPPS has won a contract to replace the computing environment and plant models for the Susquehanna Unit 1 full scope simulator. Work is underway and the upgraded simulator is targeted to be in service by the third quarter of 2016.

The new Susquehanna Unit 1 simulator will use L-3’s graphical simulation PC/Windows-based tools for the plant models and instructor station. The entire Unit 1 power plant will be simulated in the Orchid simulation environment, including L-3’s Comet Plus™ reactor model, ANTHEM™ steam supply system model, balance of plant systems, electrical systems and I&C systems.

The simulator will also be equipped with new 2-D and 3-D animated, interactive visualizations of the reactor vessel, containment building and spent fuel pool to provide operators with a real-time understanding of the plant’s behavior during normal and abnormal operations and during severe accidents. The 2-D graphics will be enabled with L-3’s Orchid Control System, and 3-D visuals will be powered by Bridgeworks© from TriLink Systems.
