L-3’s Orchid Core Builder is a graphical utility used to create and validate cycle-specific reactor core data. The utility generates an advanced reactor kinetics model (Comet Plus) based on the Nodal Expansion Method. It will be used to update the simulator’s fuel cycle data to the latest plant data, and the Comet Plus reactor model will support an 18-month refueling cycle to reflect the upgraded refueling cycle undertaken at the plant. The updated model is set to be completed in fourth quarter 2016.
