​SHARP - Multiphysics Toolkit

Simulation-based High-fidelity Advanced Reactor Prototyping (SHARP) toolkit is a framework for multiphysics calculations featuring tightly-coupled neutronics, thermo-fluid-structural dynamics analysis capabilities. By modeling the interrelated phenomena through coupled single-physics solvers like PROTEUS, Nek5000 and DIABLO, SHARP aims to extend high-fidelity capabilities of these constituent codes to capture the integral effects through multiphysics simulations and help understand/reduce the uncertainty in conventional computational codes/methods. The high-fidelity pin-by-pin multiphysics capabilities with fully-resolved neutronic (via heterogeneous deterministic neutron transport in exact geometries), thermal (via 3-D CFD models), stress/strain (via 3-D CSM models) primarily target the leadership class supercomputers. However, a range of reduced-order models/methods are also being pursued for more common computing platforms.
