Wolsong NPP (Credit: KHNP)Canada-based L3 MAPPS has signed a deal with Korea Hydro and Nuclear Power Co Ltd (KHNP) to redevelop the full scope operator training simulator for the Candu reactor at unit 1 of South Korea’s Wolsong nuclear plant. The new system will become the primary training simulator for  Wolsong 3. The project will begin immediately, and the simulator should be in service by the third quarter of 2020.

“L3 MAPPS is pleased KHNP decided to convert the Wolsong 1 simulator contracted in 2016 to become the operator training platform for Wolsong 3,” commented Michael Chatlani, vice president of marketing and 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 simulator, like the Wolsong 1 full scope simulator, will use L3’s PC/Windows-based graphical simulation tools for the plant models as well as the instructor station. All the plant systems will be simulated including the reactor, nuclear steam supply systems (NSSS), balance of plant systems, electrical systems and instrumentation & control systems.

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

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

L3 noted that the Wolsong 3 simulator would include severe accident simulation capabilities through the Modular Accident Analysis Program, known as MAAP4-CANDU. The simulator will be equipped with two-dimensional and three-dimensional animated, interactive visualisations of the reactor vessel and containment building to provide trainees an insight into the behaviour of the plant during unlikely severe accidents.
