SHARP (Simulation-based High-efficiency Advanced Reactor Prototyping) is a modern suite of codes to simulate the key components of a fast reactor core. The SHARP toolkit is organized as a collection of modules, each representing the key components of the physics to be modeled — neutron transport, thermal hydraulics, fuel/structure behavior — together with pre- and post-processing for geometry definition, mesh generation, visualization, user interface, etc. The physics models are designed to make minimal possible use of lumped parameter models, homogenization, and empirical correlations in favor of more direct solution of the fundamental governing equations, when sufficient computing resources are available. Thus, one of the key design goals is to effectively leverage leadership class computing resources — viz. BG/P and Cray Supercomputers that are on the current trajectory to delivering sustained petaflops performance. In this poster we will discuss our initial lightweight and loosely coupled framework, its initial design, and our long term plan.
