N2 - As the nuclear industry advances to meet the needs of lower carbon emissions in the United States, many new reactors are under development that are cooled by water, high-temperature gases, and other fluids. To aid the analysis and design of these reactors, nuclear plant modeling programs must advance with the nuclear and computer industries. RELAP5-3D is continually upgraded to serve the needs of the nuclear industry and to operate correctly on new computer architecture, compilers, and operating systems. Recent improvements include the addition of air as a working fluid and improvement of the accuracy of the hydrogen and nitrogen tables for modeling reactors, experiments, and other fluid systems, the addition of a dissolved gas model for water reactors, and the extension of the molecular diffusion model to numerous noncondensable gases for accident scenarios with gas reactors. Lastly, RELAP5-3D's recent adaptation to the widely available GNU Fortran is also expect to improve its utility to the industry for many years to come.
