FATE 2.0 (Facility Flow, Aerosol, Thermal and Explosion Model)

FATE 2.0 (Facility Flow, Aerosol, Thermal and Explosion Model) software is designed to replace computer codes currently used for design and safety analyses for U.S. Dept. of Energy projects at the Hanford site and elsewhere. These include codes such as HADCRT for tank farms and waste treatment plants and WESF, PFP, HANSF MCO and HANSF for spent nuclear fuel, sludge and the site’s “T plant” chemical separation facility. New features include the flammability and combustion of gases, vapors and aerosols model, and entrainment of deposits to form aerosols modeling. Other models include thermal radiation networks, event-oriented simulation and a limited distribution fire model. General capabilities include multiple-compartment thermodynamics and general species analysis, facility nodalization and flow, aerosol behavior, heat transfer determination, sources and time-dependent conditions, and nuclear fuel and sludge models including chemical reactions.
