One order will provide for the addition of an alternate emergency power system (AEPS) model. In the other order, L-3 Mapps will modify the interface between its Orchid Core Builder and the fuel analysis code used to perform the actual nuclear power plant fuel cycle updates.
The AEPS added to the station includes four, 2 MW diesel generators located 1.5 miles off-site to provide an alternate source of power during a station blackout that is different from the emergency diesel generators and off-site resources. The off-site diesel back-up systems start up when there is a loss of both safety-related emergency diesel generators and a loss of off-site power. As an enhancement to the simulator, L-3 Mapps will model the AEPS generators associated switchgear, transformers and connection to the Central Electric Power Co-op, all with L-3 Mapps’ Orchid Modeling Environment. Invensys’ Wonderware InTouch human-system interface for the AEPS will be emulated with L-3 Mapps’ Orchid Control System.
As part of the second order, the interface between Orchid Core Builder and the data generated by the fuel analysis code will also be updated as the Callaway Energy Center transitions from CASMO4/SIMULATE3 to Westinghouse’s PHOENIX-P/ANC.
The AEPS model upgrade is scheduled to be completed byNovember 2011 and the fuel data input model will be updated in the fourth quarter of 2011.
