Need Recommendations for Nuclear Reaction Modelling Software

AI Thread Summary
Recommendations for nuclear reaction modeling software include MCNP, which is considered an industry standard. Users are encouraged to clarify their specific applications, particularly regarding the effects of fuel pellet shapes on fission density and self-shielding. The discussion highlights the importance of modeling various reactions, including neutron capture, scattering, and fission products. Understanding the complexities of different fuel types, such as uranium, plutonium, and thorium, is also emphasized. Overall, the thread seeks insights into effective tools and methodologies for simulating nuclear reactions.

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)?

Thread 'MCNP6 BURN Card Issue: Zero Burnup for Material in Fuel Assembly'

Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information（power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.） for Material 2 is zero, while Material 1...

Thread 'Beginner Seeking Help: MCNP6 Burnup Example (OECD-NEA Benchmark)'

Hi everyone, I'm a complete beginner with MCNP and trying to learn how to perform burnup calculations. Right now, I'm feeling a bit lost and not sure where to start. I found the OECD-NEA Burnup Credit Calculational Criticality Benchmark (Phase I-B) and was wondering if anyone has worked through this specific benchmark using MCNP6? If so, would you be willing to share your MCNP input file for it? Seeing an actual working example would be incredibly helpful for my learning. I'd be really...
