TRAC-PD2 independent assessment

Technical Report ·
OSTI ID:6069337
The Los Alamos National Laboratory is developing the Transient Reactor Analysis Code (TRAC) to provide an advanced best-estimate predictive capability for the analysis of postulated accidents in light-water reactors. The TRAC-PD2 program provides this analysis capability for pressurized water reactors and for many thermal-hydraulic test facilities. The code features a three-dimensional treatment of the pressure vessel and its associated internals, two-phase nonequilibrium hydrodynamic models, flow-regime-dependent constitutive relations, optional reflood=tracking capability for both bottom-reflood and falling-film quench fronts, and consistent treatment of entire accident sequences, including the generation of consistent steady-state conditions. The Los Alamos report, TRAC-PD2: An Advanced Best-Estimate Computer Program for Pressurized Water Reactor Loss-of-Coolant Accident Analysis, LA-8709-MS (NUREG/CR-2054), provides a detailed description of the code. This report documents the Los Alamos results of the second assessment phase, independent assessment, for TRAC-PD2.
