L3 MAPPS has signed a deal with Korea Hydro and Nuclear Power Co Ltd (KHNP) to redevelop the Wolsong Unit 1 (Wolsong 1) CANDU* full scope operator training simulator.

It is due to be in service by the third quarter of next year.

The system will become the primary training simulator for Wolsong Unit 3 (Wolsong 3). The project will begin immediately.

“L3 MAPPS is pleased KHNP decided to convert the Wolsong 1 simulator contracted in 2016 to become the operator training platform for Wolsong 3,” said Michael Chatlani, Vice President of Marketing & Sales for L3 MAPPS Power Systems and Simulation. “We were near completion of the Wolsong 1 simulator, so it is extremely gratifying that all the hard work that went into the simulator will be leveraged for Wolsong 3.”

The Wolsong 3 full scope simulator, like the Wolsong 1 simulator, will use L3’s PC/Windows-based graphical simulation tools for the plant models and instructor station. All the plant systems will be simulated, including the reactor, nuclear steam supply systems, balance of plant systems, electrical systems and I&C systems.

The Wolsong 3 simulator models will be based on planned adjustments to the Wolsong 1 simulation that have already been developed, validated and maintained in L3’s state-of-the-art Orchid® simulation environment.

The Digital Control Computers (DCCs) will be represented by an emulated DCC that will be integrated into the full-scope simulator. The Wolsong 1 simulator’s full replica main control room (MCR) panels will be returned to Canada to be upgraded to accurately represent the Wolsong 3 MCR.

The Wolsong 3 simulator will also include severe accident simulation capabilities by including a version of the Modular Accident Analysis Program, known as MAAP4-CANDU**. The simulator will also be equipped with two-dimensional and three-dimensional animated, interactive visualisations of the reactor vessel and containment building to provide trainees further insight into the behavior of the plant during unlikely severe accidents.
