L-3 Mapps has won a contract from Pacific Gas and Electric Co. (PG&E, NYSE: PCG) to upgrade the Operator Training Simulator (OTS) at the 2,300 MW Diablo Canyon Power Plant (DCPP) near San Luis Obispo County, Calif.

The Diablo Canyon OTS upgrade project involves rehosting the legacy simulation models to modern simulation servers based on PC/Windows technology with L-3’s Orchid Simulator Executive to manage the models. It also involves replacing the original instructor station with Orchid Instructor Station; replacing the reactor core neutronics model with L-3’s high-fidelity reactor core model, which is generated and validated with Orchid Core Builder; replacing the reactor coolant system thermal-hydraulic model with L-3’s Anthem model, which is developed and tested in Orchid Modeling Environment; replacing the legacy chemical and volume control system (CVCS) models with updated CVCS models developed with Orchid Modeling Environment; and replacing the existing input/output system, which allows the simulation servers to communicate with the simulator main control room panel instruments, with a commercial-off-the-shelf I/O system that will be driven by Orchid Input Output.

Work is currently underway now, with project completion expected by the fourth quarter of 2013.
