software_title: "DUCTED ASSEMBLY STEADY STATE HEAT TRANSFER SOFTWARE"
doi: "https://doi.org/10.11578/dc.20210823.1"
description: "The Ducted Assembly Steady State Heat transfer software (DASSH) performs\
  \ full core, steady state, subchannel temperature calculations for hexagonal, ducted\
  \ assemblies. DASSH is targeted for use in the early stages of the reactor design\
  \ process when assembly characteristics may not be defined or are undergoing considerable\
  \ changes. DASSH provides a relatively rapid assessment of the temperature and flow\
  \ distribution to inform reactor design updates and analysis."
