[ RadSafe ] [Fwd: RE: uranium combustion produces how much UO3(g)?]

[Eric D]

I had a discussion with Dr. Alexander and others on this issue and the
primary issue is temperature.  While the temperature of burning DU is high
while it is burning, it rapidly cools (seconds) to ambient temperature which
causes the rapid condensation of the vapor into U3O8.  As shown in the phase
graph in Dr. Alexander's paper, UO3 occurs at temperatures on the order of
1000K.  The cooling causes it to change to U3O8.  The results of the
Capstone Study are consistent with this.  The statement that UO3 vapor poses
a significant hazard is not.

I would welcome any additional information on the topic.
