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.

The conversion reaction of tritium gas (T2) to tritiated water was studied experimentally at initial tritium concentrations between 9.6 × 10−3 and 48 GBq · m−3 (2.6 × 10−4 and 1.3 Ci · m−3) in air. Effects of water vapor and catalysts on the conversion reaction were also examined. Stainless steel, copper, paint, and platinum black were used as potential catalytic surfaces. First-order rate constants for the reaction in air are found to be independent of initial tritium concentration, and there is no effect from water vapor on the reaction. The conversion is insensitive to the presence or absence of stainless steel and copper. Paint sorbs T2 and HTO, but the latter is desorbed from the paint by heating. Platinum black produces the expected increase in the rate of reaction.
