Canada’s L3 MAPPS said on 7 November that it had signed a seven-year agreement with ENGIE Electrabel to provide support services for the full scope simulator at Belgium’s Tihange 1.

The simulator, which has been in service since 2016, is equipped with replica control room panels and is based on L3’s state-of-the-art graphical simulation PC/Windows-based tools for the plant models and instructor station.

Most of the plant systems are simulated in the Orchid® simulation environment, including the reactor, nuclear steam supply systems, balance of plant systems, electrical AC and DC distribution systems, and I&C systems. The electrical grid, including the main generators and transformers, is modelled with FAST, a product of ENGIE Tractebel.

The support agreement includes hosting a replica of the Tihange 1 simulator software at L3 MAPPS’ Montreal facility, both remote and onsite support, and regular updates to the Orchid software.

Tihange 1 is a 962MWe three-loop pressurised water reactor, which was commissioned in 1975 and is expected to be operational until 2025.
