Above critical temp (IIRC close to 40K) D2 has no liquid state per se.
Supercritical fluid would seem more appropriate. The moderator needs a certain density.

One way to determine the superiority of deuterium to heavy water would be to determine the density of deuterium necessary to give the same moderator ratio as heavy water. From that density, then determine the pressure required. Then determine the necessary requirements of the pressure vessel and its material to contain that pressure.
