PAD: a one-dimensional, coupled neutronic-thermodynamic-hydrodynamic computer code

Technical Report ·
DOI:https://doi.org/10.2172/7222862· OSTI ID:7222862

Theoretical and numerical foundations, utilization guide, sample problems, and program listing and glossary are given for the PAD computer code which describes dynamic systems with interactive neutronics, thermodynamics, and hydrodynamics in one-dimensional spherical, cylindrical, and planar geometries. The code has been applied to prompt critical excursions in various fissioning systems (solution, metal, LMFBR, etc.) as well as to nonfissioning systems.
