L-3 MAPPS Reaches Major Milestone on Ling Ao Phase II Simulator Project

L-3 MAPPS has announced that the Ling Ao Phase II nuclear power plant full scope simulator (FSS), the first-ever simulator for a CPR1000 plant, has attained another significant milestone. In a ceremony held in Paris on 28 June 2011 marking the issuance of the provisional acceptance certificate (PAC), L-3 MAPPS joined AREVA, Siemens, Daya Bay Nuclear Power Operations and Management Company (DNMC) and China Nuclear Power Engineering Company (CNPEC) to formally hand over the simulator to DNMC on behalf of the Ling Dong Nuclear Power Company.

In cooperation with AREVA and Siemens, L-3 MAPPS successfully delivered and installed the FSS in August 2009. The first plant license operator examinations were successfully carried out on the FSS and witnessed in January 2010 by China’s nuclear regulatory authority, the National Nuclear Safety Administration. Unit 1 of the Ling Ao Phase II complex entered commercial operation in September 2010 and Unit 2 is planned for August 2011.

To achieve PAC, the simulator was updated to account for all plant changes since the August 2009 simulator delivery, including commercial operation results. A simulator availability test was performed, which demonstrated a simulator availability of 99.42%. With this milestone achieved, the simulator’s warranty period is now underway.

“With the plant and digital control systems (DCS) designs being firmed up in parallel with the simulator’s development, the supplier and customer teams faced tremendous hurdles to complete this project,” said Peter Dawson, president of L-3 MAPPS. “We are extremely proud of what the team has accomplished on the Ling Ao Phase II program and are grateful to so many contributors, including representatives from DNMC, CNPEC, AREVA and Siemens for their outstanding collaboration.”

Integrated with AREVA- and Siemens-supplied DCSs, replica control room panels, and a stimulated human-machine interface, the FSS features L-3 MAPPS’ advanced instructor station capabilities and a proven Windows-based graphical simulation environment. Advanced plant models have been deployed and validated for the reactor, thermal-hydraulic, balance of plant, electrical, and I&C for the turbine control and other miscellaneous systems not controlled by the AREVA/Siemens DCSs. The safety systems DCS is AREVA’s Teleperm XS, and the operational I&C DCS system is Siemens’ SPPA-T2000 with OM690 human-machine interface.

The Ling Ao Phase II nuclear plant, owned by Ling Dong Nuclear Power Company, comprises the first two CPR1000 generating units put into service. The CPR1000 is a Chinese standard design featuring a 1,080MW three-loop pressurized water reactor, whose design is coordinated by CNPEC. Both the plant and the simulator are located in Da Peng on the coast of Daya Bay in Guangdong Province, about 45km from the city centre of Shenzhen and about 50km from Tsim Sha Tsui, Hong Kong Special Administrative Region.
