Simulator updates for Ling Ao

18 August 2014

L-3 MAPPS has signed a contract with three Chinese companies to provide reactor core model-related services for three simulators at the Daya Bay Training Center in Guangdong Province, China.

The contract is with Daya Bay Nuclear Power Operations and Management Company, Ling Ao Nuclear Power Company and Ling Dong Nuclear Power Company. LANPC owns Ling Ao 1&2 (Phase I), which comprise two 938 MWe three-loop AREVA PWRs. LDNPC owns Ling Ao 3&4 (Phase II), 2x1080MW CPR1000 reactors. All four units are operated by DBNPOC.

"The project aims to introduce a higher level of consistency between the older Ling Ao and the newer Ling Ao Phase II simulators, while improving the fidelity of the Ling Ao simulator's reactor model," says Michael Chatlani, vice president of marketing & sales for L-3 MAPPS.

The Ling Ao full scope simulator, built by L-3 MAPPS, was put into service in October 2003. The two Ling Ao Phase II full scope simulators entered into service in August 2009 and were built by L-3 MAPPS in cooperation with AREVA and Siemens.

L-3 says that as part of the project its Orchid® Core Builder, a graphical utility for the creation and validation of cycle-specific reactor core data, will be employed to update the fuel cycle data to the latest plant fuel cycle data on the two full scope simulators for the Ling Ao Phase II nuclear plant.

In addition, Orchid Core Builder will be added to the Ling Ao full scope simulator to make it consistent with the Ling Ao Phase II simulators. The original Comet™ reactor model will also be replaced with the Comet Plus™ model, and a similar fuel cycle update will be performed.

Work is beginning immediately, and is expected to be completed in the first quarter of 2015.
