L-3 MAPPS to Update Ling Ao and Ling Ao Phase II Reactor Core Models

Ling Ao simulator

L-3 MAPPS has announced that it has signed a contract with Daya Bay Nuclear Power Operations and Management Company (DNMC), the Ling Ao Nuclear Power Company (LANPC) and Ling Dong Nuclear Power Company (LDNPC), to provide reactor core model-related services for three simulators at the Daya Bay Training Centre near Shenzhen, Guangdong Province, China.

The project will commence immediately and the simulators are all expected to be in service in the first quarter of 2015.

L-3 MAPPS marketing and sales vice-president Michael Chatlani said: "It is an honour to continue supplying advanced simulation software and services to our esteemed customers in the China General Nuclear Power Group.

"Through these updates, we expect 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."

L-3’s Orchid® Core Builder 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, the Orchid Core Builder will be added to the Ling Ao full scope simulator to make it consistent with the Ling Ao Phase II simulators, while the original Comet™ reactor model will be replaced with the Comet Plus™ model, and a similar fuel-cycle update will be performed.

Orchid Core Builder is L-3 MAPPS’ graphical utility for the easy creation and validation of cycle-specific reactor core data. The utility generates an advanced reactor kinetics model (Comet Plus) based on the nodal expansion method. Orchid Core Builder is also equipped with an initial condition (IC) transfer mechanism to automate the process of creating ICs following fuel-cycle updates.

The Ling Ao Phase II nuclear plant, owned by the Ling Dong Nuclear Power Company, comprises the first two CPR1000 nuclear generating units that were put into commercial operation. The first unit went into operation in September 2010 and the second in August 2011.

The CPR1000 is a Chinese standard design featuring a 1,080MW three-loop pressurised water reactor (PWR). The Ling Ao Phase II full scope simulator, built by L-3 MAPPS in cooperation with AREVA and Siemens, was put into service in August 2009.

The Ling Ao nuclear plant, owned by the Ling Ao Nuclear Power Company, comprises the two AREVA-designed 938 MWe three-loop PWR units that were put into commercial operation in February 2002 and December 2002. The Ling Ao full scope simulator, built by L-3 MAPPS, was put into service in October 2003.

L-3 MAPPS has over 30 years of experience in pioneering technological advances in the marine automation field and over 40 years of experience in delivering high-fidelity power plant simulation to leading utilities worldwide.

In addition, the company has more than four 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. To learn more about L-3 MAPPS, please visit the company’s website at www.L-3com.com/MAPPS.
