Description
GUARDYAN (GPU Assisted Reactor Dynamic Analysis) is a continuous energy Monte Carlo (MC) neutron transport code developed at Budapest University of Technology and Economics. It targets to solve time-dependent problems related to fission reactors with the main focus on simulating and analyzing short transients. The key idea of GUARDYAN is a massively parallel execution structure making use of advanced programming possibilities available on CUDA enabled GPUs. Compared to similar code systems GUARDYAN is the first to upscale to nuclear power plant levels targeting the simulation of analyzing severe accident scenarios for reactor safety analysis. Recent advances include the coupling with thermal-hydraulics solvers and comparison to actual measurements at the Paks Nuclear Power Plant.
