= GUARDYAN GUARDYAN (GpU Assisted Reactor DYnamic ANalysis) is a Monte Carlo based neutrontransport program running on GPU (Graphics Processing Unit) for simulating '''reactor transients'''. The simulation tracks neutrons in a three dimension space bounded by second degree surfaces while they interact with the isotopes present in the region. Cross Section Data may be given in ACE (A Compact ENDF ) format coming from ENDF (Evaluated Nuclear Data File) cross section table. The current version of the code supports time- and temperature dependent cross sections, thermal feedback is included in future releases.
