Title: Challenges in Large-scale Modeling and Simulation for Nuclear Systems. The increase in affordable computing capacity, in availability of computer codes designed for high performance computing, and in the need for varying levels of solution fidelity for analysis, design and licensing of complex nuclear systems has driven a desire for multi-scale, multi-physics modeling and simulation capabilities and has required dramatic shifts in the size and fidelity of computational models and computer simulations. This roundtable will feature perspectives from both developers and appliers of computer codes for modeling and simulation across a number of nuclear systems. The purpose is to have an application-focused discussion of how the needs of various emerging nuclear applications are driving the development of tools for analysis and design of complex nuclear systems, and the challenges that are emerging.
