CAE’s new ROSE® 4 Simulation Environment chosen for Upgrade of SCE’s SONGS Unit 2 Nuclear Plant Simulator

Toronto, February 6, 2003 (NYSE: CGT; TSX: CAE) CAE, a world leader in the supply of power plant simulators, today announced that Southern California Edison (SCE) has once again chosen the ROSE® graphical modeling environment for the upgrade of its Unit 2 simulator at San Onofre Nuclear Generating Station (SONGS).

SONGS Unit 2 is an 1100 MW Combustion Engineering pressurized water reactor (PWR), one of two operational reactors at the generating station located on the Pacific coast near San Clemente, California.

‘Southern California Edison was one of CAE’s first customers to embrace the ROSE® concept,’ said Rashid Khan, CAE’s Executive Vice President, Marine and Power Systems. ‘CAE’s latest ROSE® 4 and other updated simulation technologies being adopted by SCE will set new standards in power plant simulation.’

Under the first phase of the upgrade program, CAE will replace the simulator’s legacy computers with a Windows-based system running CAE’s simulator executive SimStudio™. CAE will also supply an updated instructor station, replacing a Unix-based system with the most recent release of CAE’s Windows-based Isis™.

The second phase involves the replacement of the Reactor Core model, upgraded with CAE’s high fidelity COMET™, and auto-generated within CAE’s powerful Chorus™ graphic utility. As well, the Reactor Coolant System (RCS) and Containment models will be replaced with improved ROSE® 4-based models.

‘CAE’s early-1990’s upgrade of our plant simulator introduced us to ROSE® for the first time,’ said Vincent Gagnon, Simulator Project Manager of Southern California Edison, ‘We continue to be impressed with the ease of model maintenance and management within the ROSE® simulation environment.’

An Edison International company, Southern California Edison is one of the largest utilities in the U.S., serving central, coastal and Southern California. SONGS provides nearly 20 percent of the power to more than 15 million people in Southern California — enough power to serve 2.75 million households.

CAE is a global leader in providing advanced simulation and controls equipment and integrated training solutions for customers in the marine, military, and civil aviation markets. With annual revenues in excess of $1 billion, CAE employs more than 6,000 people in Canada, the United States and around the globe.
