L-3 Mapps to Upgrade Simulator at Romanian Nuclear Plant

L-3 Mapps to Upgrade Simulator at Romanian Nuclear Plant

L-3 Mapps will upgrade the full scope simulator’s emulation of the plant digital control computers (DCCs) at a 1,400-MW nuclear power plant in Romania.
 
L-3 Mapps was contracted by Societatea Nationala Nuclearelectrica S.A. (SNN) of Romania to upgrade the system at the Cernavodă nuclear power plant. The project will start immediately and the upgraded software is expected to be in service in the first quarter of 2017.
 
The current Linux-based DCC simulation on the Cernavodă plant computers for units 1 and 2 emulates a single SSCI-125 computer’s instruction set and the handling of the input and output (I/O) devices managed by the DCC. The upgraded simulator will feature a dual-redundant DCC emulation on a Windows operating system with the SSCI-890 computer and related I/O. The DCC emulation is developed with L-3 Mapps’ Orchid Control system.
 
The DCC emulation supports standard DCC features, such as system switchover, failover and the ability to fail individual programs. It also includes advanced built-in debugging and monitoring tools for a better understanding of the behavior of the DCC executive programs.
 
Units 1 and 2 are both 706-MW CANDU reactors that have been in operation since December 1996 and October 2007, respectively.
