Impact of HPC on Nuclear Energy: Advanced Simulations for the Westinghouse AP1000® Reactor

SESSION: Tuesday HPC Impact Showcase Presentations

EVENT TYPE: HPC Impact Showcase & Emerging Technologies

TIME: 11:40AM - 12:20PM


Speaker(s):Fausto Franceschini

ROOM:Show Floor - 233 Theater


Westinghouse Electric Corporation, a leading supplier of nuclear plant products and technologies, performed advanced simulations on the Oak Ridge Leadership Computing Facility that reproduce with unprecedented facility the conditions occurring during the startup of the AP1000 advanced nuclear reactor. These simulations were performed using advanced modeling and simulation capabilities which are developed by the Consortium for Advanced Simulation of Light Water Reactors (CASL), a U.S. Department of Energy (DOE) Energy Innovation Hub led by the Oak Ridge National Laboratory. The AP1000 reactor is an advanced reactor design with enhanced passive safety and improved operational performance, with eight units currently being built, four in China and four in the U.S.

The high-fidelity simulation toolkit used for this effort corroborated a complete understanding of the behavior for this advanced reactor design. The novel simulations performed have been accomplished using a 60 million core-hour allocation Early Science award on the Oak Ridge Leadership Computing Facility TITAN. Use of the CASL advanced nuclear methods and software techniques, properly designed to take advantage of these vast computational resources, has been a key factor to this successful endeavor. Prior to this project, results of comparable fidelity were unavailable due to the impractical computational time resulting from limitations in codes scalabilities or computational resources available.

This endeavor, pursued through a collaborative effort of U.S. national labs and private industry, typifies the benefits that HPC can bring to the U.S. public by further ensuring the viability and safety of advanced energy sources.
