Need Recommendations for Nuclear Reaction Modelling Software

Click For Summary
SUMMARY

The discussion centers around recommendations for nuclear reaction modeling software, specifically for simulating different fuel pellet shapes. MCNP (Monte Carlo N-Particle Transport Code) is highlighted as an industry-standard simulation package suitable for this purpose. Key considerations for modeling include fission density, self-shielding effects, and the geometry of the pellet shapes. The conversation also touches on the need to model neutron capture, scattering, and the reactions of fission products alongside the fuel materials such as Uranium, Plutonium, and Thorium.

PREREQUISITES
  • Understanding of nuclear reaction principles
  • Familiarity with MCNP (Monte Carlo N-Particle Transport Code)
  • Knowledge of fission density and self-shielding effects
  • Basic concepts of neutron capture and scattering
NEXT STEPS
  • Research MCNP documentation for modeling nuclear reactions
  • Explore the effects of pellet geometry on fission density
  • Study neutron capture and scattering techniques in nuclear physics
  • Investigate the behavior of fission products in nuclear reactions
USEFUL FOR

Nuclear engineers, researchers in nuclear physics, and anyone involved in modeling nuclear reactions and fuel pellet designs will benefit from this discussion.

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?

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)?
