The Challenge

AREVA, world leader in the energy sector, has experimented a new computational method for the upper internals of nuclear reactors. ESI’s SYSTUS solvers running on Intel’s newest HPC server can simulate models of nuclear components 10 times larger than previously and 4 times faster, with greater precision.

AREVA recognizes the unmatched computing performances and reliability of SYSTUS for the design, analysis and components assessment in compliance with nuclear regulations.

The Benefits

• Ever-enhanced safety: simulate completely and accurately large nuclear components
• Optimal quality and applicability of simulation for leaders in nuclear power
• Hardware solutions with the most computational power ever on the market at affordable cost of ownership
• Precise and efficient dimensioning analyses and behavior simulations

“Some High-Performance Computing (HPC) workloads rely on large data sets and complex calculations that are not easily distributed across large numbers of smaller servers. Intel® Xeon® processor 7500 series-based servers and their large shared memory capabilities are ideal for these demanding applications.
This super HPC node delivers the necessary compute power, large memory capacity and memory bandwidth performance to solve big science faster.”
