The ATHENA code is being developed by EG&G Idaho as a general purpose thermal hydraulics code for safety transient analysis of fusion reactors. This report documents the use of ATHENA to model a lithium-lead cooled fusion reactor design. The code models the MHD effects resulting from the flow of a conducting fluid through a strong steady magnetic field. The code performed well within the range of available lithium-lead properties. The results from calculations of several operational transients and a loss of pumping power are reported.
