Montréal, March 12, 2007 - L-3 Communications MAPPS, a wholly owned subsidiary of L-3 Communications, announced today that it has entered into an agreement with Korea Power Engineering Company, Inc. (KOPEC) to modernize the Wolsong Simulator on behalf of Korea Hydro & Nuclear Power Co., Ltd. (KHNP).The Wolsong Simulator is used by KHNP to support operator training for its 700-megawatt-class Wolsong 2, 3 and 4 CANDU* nuclear power plant units located along the eastern shoreline of South Korea (Republic of Korea) at Yangnam, Kyungju.

With KOPEC serving as project manager, L3 MAPPS and KOPEC will cooperate in providing new instructor stations, replacing the simulator's RISC/Unix-based computers with PC/Windows-based servers, and replacing the existing simulation models with higher fidelity models generated with the ChorusT model generation and update facility for the reactor, and with the ROSE® visual simulation environment for the remaining plant systems. In addition, the simulator's stimulated Digital Control Computer (DCC) will be replaced by a software-based emulation.

The original Wolsong Simulator was developed by L3 MAPPS and was put into service in September 1998. The current modernization effort is expected to take 22 months and follows the recent completion of a similar simulator modernization project for Romania's Cernavoda Unit 1 nuclear reactor.

KOPEC, headquartered in Gyeonggi, Republic of Korea, was founded in 1975 and is Korea's leading power plant designer and constructor. KOPEC has designed 14 nuclear power plants, including the development of Korea's next-generation APR1400 nuclear power plant. KOPEC has also designed and built over 40 coal-fired, combined-cycle and cogeneration plants. KHNP, headquartered in Seoul, Republic of Korea, is the largest power generator in South Korea, owning 29% of the nation's power generation facilities and supplying 40% of its electricity. KHNP operates 20 nuclear generation units at four sites: Kori, Yonggwang, Ulchin and Wolsong.

L3 MAPPS has over 20 years of experience in pioneering technological advances in the marine automation field and over 30 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. L3 MAPPS also provides targeted controls and simulation solutions to the space sector.
