Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Gravity-driven countercurrent two-phase flow, in channels connected to a sealed tank at one end and open to the atmosphere at the other end, was analytically studied. This type of gravity-driven countercurrent two-phase flow can occur during the operation of passive safety coolant injection systems of advanced reactors. A mechanistic model was developed for the oscillating flow regime, which occurs in inclined channels with a side-entry configuration when the channel angle of inclination with respect to the horizontal plane is more than 10 deg and in channels with a bottom-entry channel-tank interphase. The model was shown to satisfactorily predict the experimental data.
