L-3 MAPPS Wins Service Contract for Hongyanhe Phase I Simulator Update

"We are pleased to have another opportunity to support our colleagues at Hongyanhe," said Michael Chatlani, vice president of marketing & sales for L-3 MAPPS Power Systems and Simulation. "L-3 MAPPS is proud to offer the capabilities of our robust Orchid® technology being used to develop and maintain the Hongyanhe Phase I simulator, and we look forward to further opportunities to work together with LHNP."

L-3’s Orchid Core Builder will be used to update the simulator’s fuel cycle data to the latest plant data. The updated Comet Plus™ reactor model will support an 18-month refueling cycle to reflect the upgraded refueling cycle undertaken at the nuclear plant.

Orchid Core Builder is L-3 MAPPS’ graphical utility for the easy creation and validation of cycle-specific reactor core data. The utility generates an advanced reactor kinetics model (Comet Plus) based on the Nodal Expansion Method. Orchid Core Builder is also equipped with an initial condition (IC) transfer mechanism to automate the process of creating ICs following fuel cycle updates.
