Discussion Overview

The discussion revolves around the density of 5% enriched uranium, with participants seeking specific values and sources for this information. The scope includes material properties and potential references related to uranium compounds.

Discussion Character

  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant expresses difficulty in finding the density value for 5% enriched uranium and requests assistance.
  • Another participant asks for clarification on the specific form of uranium being referenced, suggesting various compounds such as UO2, UN, and others.
  • A participant proposes a density value of 14300 kg/m3 (14.3 g/cm3) for uranium nitride (UN) and mentions the need to verify this value and its caveats.
  • The same participant provides references to papers discussing the material properties of uranium mononitride and other related materials.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the specific density of 5% enriched uranium, and there are multiple references to different uranium compounds, indicating a lack of agreement on the exact material in question.

Contextual Notes

The discussion does not clarify the assumptions regarding the form of uranium being referenced, nor does it resolve the potential differences in density values for various uranium compounds.

I can't seem to find a value for Uranium enriched to the 5% level. Does anyone know it or know where I can find it?

THanks!

Of uranium metal, UO2, or UN or UC, or U-silicide, U-Al, U-hydride?
 
UN (Uranium Nitride)
 
A quick number would be 14300 kg/m3 (14.3 g/cm3), but let me see if I can find a better value and the caveats.

I did a quick check and the number stated is the best that I can find.

Here is a paper on metal nitrides including UN.

Also, see this paper - Steven L. Hayes, James Kelly Thomas, and Kenneth L. Peddicord, "Material Properties of Uranium Mononitride: Part I. Physical Properties," Journal of Nuclear Materials, Vol. 171, 262-270 (1990). One can purchase it from Science Direct.
