L-3 MAPPS to replace Gentilly-2 computers

28 July 2009

L-3 MAPPS has won an order from Atomic Energy of Canada Limited (AECL) to replace the Gentilly-2 Nuclear Generating Station’s Digital Control Computers (DCCs), it said 27 July.

DCC systems are used to monitor and control the major reactor and power plant functions at CANDU nuclear power plants. The DCC replacement project is part of a plant refurbishment project which will extend the life of Gentilly-2 until approximately the year 2040.

The new DCCs will feature the latest SSCI-890 CPUs and modern VME-based replacements for the existing Ramtek display system and contact scanner. These DCC CPUs will replace four Varian 73 computer systems and related input/output and ancillary equipment currently in use at Gentilly-2. The system will be delivered to Gentilly-2 in the summer of 2011.

“Through our long-standing relationship with AECL, L-3 MAPPS is pleased to play its part in extending the life of the Gentilly-2 station,” said Michael Chatlani, vice president of marketing & sales for L-3 MAPPS power systems and simulation.

Hydro-Québec has operated Gentilly-2, a 675MW CANDU heavy water reactor, since start-up in 1983. Gentilly-2 is located in Bécancour, Québec, about 90 minutes east of Montreal near the town of Trois-Rivières, and is the only nuclear power plant in the province of Québec.
