L-3 Mapps Lands Two Simulator DCS Implementation Orders

L-3 MAPPS, a subsidiary of L-3 Communications, announced today that it has recently been awarded contracts from Westinghouse Electric Company and China Techenergy Company (CTEC) to assist the two companies with integrating their new plant control systems on the simulators at the Krsko and Daya Bay sites, respectively. Both simulator projects are part of larger DCS (Distributed Control System) modernization efforts being carried out by Westinghouse and CTEC at the actual power plant units.

Under contract to Slovenia’s Nuklearna elektrarna Krsko (NEK), Westinghouse is replacing the Krsko plant’s turbine control system, turbine emergency trip system and moisture separator reheater controls with its Ovation-based DCS to improve equipment reliability, availability and maintainability. L-3 MAPPS will interface an emulated DCS equivalent on the simulator, which involves the development of an interface bridge and the modification of the legacy Krsko simulator process models to accommodate the new DCS. The Krsko full scope simulator was delivered by L-3 MAPPS in December 1999 and taken over by NEK in March 2000.

Similarly, under contract to Daya Bay Nuclear Power Operations and Management Company (DNMC), CTEC is developing a replacement for the two Daya Bay units’ data processing and safety monitoring systems – known as “KIT/KPS” – using its HOLLiAS DCS platform. L-3 MAPPS will remove the Daya Bay simulator’s driver software that communicates with the current stimulated KIT/KPS and replace it with a new driver, allowing the simulator to communicate with the replacement system being provided by CTEC. The Daya Bay simulator, retrofitted by L-3 MAPPS, has been in operation by DNMC since March 2006.

Westinghouse, a group company of Toshiba Corporation, is the world’s pioneering nuclear power company and is a leading supplier of nuclear plant products and technologies to utilities throughout the world. Westinghouse supplied the world’s first Pressurized Water Reactor in 1957 in Shippingport. Today, Westinghouse technology is the basis for approximately one-half of the world’s operating nuclear plants.

China Techenergy Company, a joint venture between China Guangdong Nuclear Power Company and Beijing HollySys specializes in engineering design and the application of DCSs for nuclear power plants, and safety DCS research and development. It has been contracted to supply several DCSs for nuclear utilities, such as for six units for the CPR1000 Extension Project in Dalian and Ningde, PR China.

L-3 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. L-3 MAPPS also provides targeted controls and simulation solutions to the space sector.

Headquartered in New York City, L-3 Communications employs over 63,000 people worldwide and is a prime system contractor in aircraft modernization and maintenance, C3ISR (Command, Control, Communications, Intelligence, Surveillance and Reconnaissance) systems and government services. L-3 is also a leading provider of high technology products, systems and subsystems. The company reported 2006 sales of US$12.5 billion.
