POWER SIMULATION
Major supplier in dynamic simulation
for the Nuclear Industry
CORYS is a world leader in high fidelity simulation for training and engineering design
We create sophisticated models of complex systems for the nuclear power industry, including fluid (single and multi-phase), gaseous, electrical and I&C systems.
Building on more than 30 years of experience developing simulations for multiple plant types, including both PWR and BWR, CORYS has developed a mature, well-proven toolset which creates highly accurate models capable of supporting engineering design and analysis as well as operator training. We offer innovative and high-tech solutions including digital twins and cloud delivery of solutions.
CORYS technology powers more simulators than any other simulator vendor in the world.
Engineering
CORYS high fidelity simulations pioneered the use of simulation for plant engineering design and analysis. Today, most nuclear plants commonly use simulation for design and testing of plant engineering.
