Upgraded Krško Full Scope Simulator Declared Ready For Training

MONTREAL, October 25, 2017 – L3 MAPPS announced today that the full scope simulator upgrade for Slovenia’s Krško Nuclear Power Plant was declared “Ready For Training.” The simulator upgrade was part of Nuklearna elektrarna Krško’s (NEK) Safety Upgrade Program (SUP) to modernize the plant in order to prevent severe accidents and to mitigate consequences consistent with the nuclear industry’s response after the Fukushima accident.

“The project was delivered on time, on budget and is now operational,” said Michael Chatlani, Vice President of Marketing & Sales for L3 MAPPS Power Systems and Simulation. “It was again our honor to work with NEK on this challenging and fulfilling project.”

“NEK’s decision to work with L3 MAPPS has once again proven to be the right decision,” said Božidar Krajnc, NEK Engineering Director. “The simulator upgrade is an important part of our safety upgrade program. Through close cooperation between the NEK and L3 MAPPS technical teams, we now have a modern, high-performance simulator that will continue to serve our training and engineering support needs.”

The simulator’s previous UNIX operating system-based simulator was replaced with a virtualized Windows-based platform running L3’s industry-leading Orchid® simulation environment. A new compact input/output (I/O) system, driven by L3’s Orchid Input Output software, was provided for the simulator’s main control room and for the newly simulated emergency control room.

After migrating the nuclear island and conventional island models into Orchid, various plant model upgrades were performed to reflect plant changes from the SUP. The severe accident simulation models were improved and an interactive 3-D visualization was added to the simulator to enhance visibility into simulated accidents.

Nuklearna elektrarna Krško operates the only nuclear power plant in Slovenia. The Krško Nuclear Power Plant, located in Vrbina in the Municipality of Krško, is equipped with a Westinghouse two-loop pressurized water reactor and has a net electrical output of 696 MWe. It is connected to the 400 kV grid, supplying power to consumer centers in Slovenia and Croatia. The plant went into commercial operation on January 1, 1983, and supplies approximately 40 percent of the total electricity produced in Slovenia. Its simulator, put into service on March 31, 2000, is primarily used to train and license main control room operators in safe and efficient plant operations.
