Dear User,
About the definition of natural Uranium, you could do for example:
MATERIAL 92.0 235.0439 18.95 235.0 235-U
MATERIAL 92.0 238.0508 18.95 238.0 238-U
MATERIAL 18.95 URANIUM (remember to define the density of your new material)
COMPOUND -0.0072 235-U -0.9928 238-U URANIUM
in this way the materials 235-U and 238-U are automatically recognized for
what concerns the low energy neutrons.
If you will have thin layer of Uranium probably you will need the LAM-BIAS
card
http://www.fluka.org/fluka.php?id=man_onl&sub=45 to perform a biasing
of the inelastic hadronic interaction length.
Cheers,
Andrea
