Montréal, May 16, 2005 - L-3 Communications MAPPS, a wholly owned subsidiary of L-3 Communications, announced today that it will carry out a significant software upgrade on the Daya Bay nuclear power plant simulator on behalf of China's Guangdong Nuclear Power Joint Venture Company (GNPJVC). The award follows on the heels of a related project, where L3 MAPPS built the Ling Ao full-scale nuclear power plant simulator for GNPJVC's sister organization Ling Ao Nuclear Power Company (LANPC). The follow-on work is targeted for completion by early 2007.

The reference plant for the Daya Bay simulator is the Guangdong Nuclear Power Station (GNPS), made up of two Framatome-designed, three-loop Pressurized Water Reactors (PWRs) in Da Keng on the coast of Daya Bay in Guangdong Province, about 45 km from the city center of Shenzhen, and about 50 km from Tsim Sha Tsui, Hong Kong SAR.

Coined the Daya Bay Simulator "Backfit," the upgrade project involves the adaptation of the Ling Ao simulator's advanced thermal-hydraulic, reactor, balance of plant, electrical systems and instrumentation and control models to be Daya Bay-specific. L-3 MAPPS will employ proven graphical simulation PC/Windows-based tools for model development and maintenance as used on the Ling Ao simulator as well as enhanced instructor station software. LANPC also has the option to deploy the latest instructor station software on the Ling Ao simulator during the development of the Backfit.

"In addition to gaining a very high-quality simulation, we have established friendship and mutual trust during our cooperation on the Ling Ao simulator project," said Li Xiaoming, manager of the technical department, GNPJVC. "We consider L3 MAPPS to be a professional and competent company committed to quality and customer satisfaction - elements that we are sure will once again contribute to a successful simulator solution for the training of our Daya Bay plant operators."

"China is the fastest growing market for nuclear power generation and our customers have demonstrated a clear commitment to quality training and safety," said Rashid Khan, president of L3 MAPPS. "We are pleased to forge ahead with GNPJVC and our other partners in China by delivering simulation solutions that will contribute to these principles."

Guangdong Nuclear Power Joint Venture Co., Ltd. was formed in 1985 and is responsible for the construction and operation of Guangdong Nuclear Power Station. Daya Bay Nuclear Power Station is the first large-scale commercial nuclear power plant built with foreign investment, equipment and technology in China. It operates two PWR units of 984 MWe each. Construction of the Guangdong Nuclear Power Station started on August 7, 1987 and the two units commenced commercial operation on February 1 and May 6, 1994, respectively. Total accumulated power generation of the plant from 1994 to 2004 exceeds 135 billion KWh, and 70 percent of its output is delivered to Hong Kong with the rest connected to the Guangdong Power Network.

L3 MAPPS, which stands for Marine Automation and Power Plant Simulation, 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. L3 MAPPS also provides targeted controls and simulation solutions to the space sector.
