Dear Danny,
you have to create a new MATERIAL named DEUTERIU, in order to have the
low-energy neutron cross sections correctly associated.
Options Z: 1, Am: 2.0079, A: 2, rho: 0.0000821(or what ever gas density you need)
The most important is to specify the Z and A
then you can create your heavy water using the DEUTERIU material
