No, not heavy water (not even heavy water could make depleted
uranium go critical -- CANDUs can use natural uranium).
. TerraPower's TWR (Travelling Wave Reactor) is a variant of the
IFR (Integral Fast Reactor) developed at Argonne National
Laboratory. It will use metal fuel and be cooled by liquid sodium
Both IFR and TWR need an initial charge of fissile material
(U-235 or Pu-239), and then they breed enough new fissile to keep
themselves going indefinitely, using ~1 ton of depleted uranium per
GWe-year of energy produced. The main difference is that the TWR
would be loaded with 60 years-worth of fuel from the start (i.e.
something like 80 tons per GWe), whereas the IFR would recycle its
fuel much more frequently, adding fresh depleted periodically, and
thus would be very much smaller.

Laser mosquito zapper interesting too, huh?
Not much of reactor design details. Moderator gotta be heavy water.
No one else would keep the neutron field critical with depleted uranium
Reactor controls sequences must be very different from the present days.
