Montréal, April 2, 2009 - L3 MAPPS has been awarded a contract from Hydro-Québec to significantly upgrade its Gentilly-2 simulator. The simulator upgrade is part of a plant refurbishment project which will extend the life of the Gentilly-2 Nuclear Generating Station until the year 2040.

“We are pleased to transform the Gentilly-2 simulator with up-to-date technology, here in the same province as our main production facility,” said Michael Chatlani, vice president, marketing & sales for L3 MAPPS Power Systems and Simulation.

To match the upgrades planned for the station, the simulator, originally delivered in the late 1980s by L3 MAPPS, will also undergo major updates. The first phase of the upgrade consists of rehosting the current UNIX-based simulation platform onto a Windows operating system running L3 MAPPS’ Orchid® simulation environment. In the second phase, the reactor core and thermal-hydraulics models will be upgraded. L3 MAPPS will replace the actual stimulated plant computer, known as Digital Control Computers (DCCs), with a fully emulated equivalent that will be integrated in the full scope simulator. Deploying a dual DCC computer emulation is a first-of-a-kind effort for CANDU* plant simulators. In addition, a test bench facility including two fully stimulated plant computers interfacing the simulator with a new card (DCC-IOSIM) will allow the Gentilly-2 technical staff to test and validate the modifications to the DCC software before implementing these changes in the plant. A user will be able to switch easily between the stimulated and emulated systems. The stimulated plant computers will incorporate SSCI-890 CPU technology, matching the CPU update to be carried out on the plant DCCs.

The order also includes optional phases which could be selected later by Hydro-Québec for emulating the plant’s new turbine control system, a new plant display system and further modeling changes. Work has already started under a pre-authorization from Hydro-Québec and the new simulator is expected to enter service progressively in various phases until fall 2011.

Hydro-Québec generates, transports and distributes approximately 35 gigawatts of electricity to Québec and the northeastern part of the United States. It has operated Gentilly-2, a standard 675-megawatt CANDU Heavy Water Reactor, with an excellent service record since start-up in 1982. Gentilly-2 is located in Bécancour, Québec, about two hours east of Montréal near the town of Trois-Rivières, and is the only nuclear power plant in the province of Québec.

L3 MAPPS, a division of the L-3 Marine & Power Systems group, has over 25 years of experience in pioneering technological advances in the marine automation field and over 35 years of experience in delivering high-fidelity power plant simulation to leading utilities worldwide. In addition, the company has more than three decades of expertise in supplying plant computer systems for Canadian heavy water reactors.
