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.

Upper plenum level oscillatory phenomena were observed in boiling water reactor upper plenum mixing experiments. These phenomena were due to the multidimensional interaction of a highly subcooled spray water injected into the upper plenum with a twophase mixture and vapor. Analysis of these phenomena was performed by TRAC-BD1, which is based on a multidimensional, nonhomogeneous, nonequilibrium, two-phase flow model to assess its predictive capability. It was found that TRAC-BD1 can predict upper plenum level oscillatory phenomena by using a simple upper plenum model that accounts for the interaction of a highly subcooled spray with vapor and a two-phase mixture.
