Need Recommendations for Nuclear Reaction Modelling Software

[Todobek]

Working on a project where I need to model nuclear reactions with different fuel pellet shapes. Does anyone have recommendations for software that's good for this? Any advice or experiences are also welcome!

Welcome to PF.

(thread moved to the Nuclear Engineering forum for now)

Do you have access to MCNP? That would seem to be an industry-standard simulation package:

Can you say more about the application you are wanting to simulate?

model nuclear reactions

What does one mean by 'model nuclear reactions' in the context of 'different pellet shapes'?

Normally, one is concerned with the fission density, self-shielding effects, and pellet shape/geometry would be a factor.

Does one intend to model neutron capture and scattering/excitation, as well as fission? Does one have to model the reactions in the fission products as well as the fuel (typically U, but also Pu or Th) and transuranics (from transmutation)?
