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)?

What is nuclear reaction modeling software used for?

Nuclear reaction modeling software is used to simulate and analyze nuclear reactions, primarily for research and development purposes in fields such as nuclear physics, nuclear engineering, and energy production. These tools help scientists and engineers understand the behavior of nuclear materials under various conditions, predict reactor performance, and design safer and more efficient nuclear systems.

What are some popular nuclear reaction modeling software?

Some well-known nuclear reaction modeling software includes MCNP (Monte Carlo N-Particle), which is widely used for neutron and photon transport calculations, and ANSYS Fluent, which provides capabilities for simulating fluid flow and reactions in nuclear reactors. Other notable software includes OpenMC, a Monte Carlo particle transport simulation code, and SERPENT, which is used for neutron transport calculations and reactor physics analysis.

Are there any free or open-source options available?

Yes, there are several free and open-source nuclear reaction modeling software available. OpenMC is an open-source Monte Carlo simulation software that is highly regarded in the nuclear engineering community. Another example is SERPENT, which is available for academic use under a free license. These tools offer robust capabilities for researchers and students without the cost of commercial software licenses.

What are the key features to look for in nuclear reaction modeling software?

Key features to look for in nuclear reaction modeling software include the ability to handle complex geometries, advanced neutron and photon transport capabilities, thermal-hydraulic simulations, and compatibility with nuclear data libraries. Additionally, user-friendly interfaces, comprehensive documentation, and active user and developer communities are important for effective use and ongoing support.

How do I choose the right software for my specific needs?

To choose the right nuclear reaction modeling software, consider your specific project requirements, such as the type of reactions and materials involved, the desired accuracy, and computational resources available. Evaluate the software's compatibility with existing systems and its ability to integrate with other tools. It's also beneficial to consult with peers or experts in your field, participate in forums, and review published research where specific software tools were utilized to understand their applications and limitations.
