Calculating Group Constants for FA with MCNP

[chivasorn]

hi there

I wnat to calculate the group constants for a FA(fuel assembly) using MCNP (similar to lattice calculations).
How can I do it? Please lead me.
Thanks a lot!

For this particular purpose, you may be more interested in a simpler tool.
For example, have a look at this program http://www.oecd-nea.org/tools/abstract/detail/NEA-1840/
