In the world of nuclear engineering, health physics, and radiological shielding, one name stands above the rest: (Monte Carlo N-Particle Transport Code). Developed by Los Alamos National Laboratory (LANL), it is considered the gold standard for simulating the transport of neutrons, photons, electrons, and other particles.

git clone https://github.com/openmc-dev/openmc – completely free. Best for: Reactor physics, criticality calculations, and learning Monte Carlo methods without legal hurdles.

But for high-assurance applications (nuclear criticality safety, spent fuel storage, weapons labs), MCNP will remain the gold standard behind a strict license wall.

However, there are two ways to get it without paying a commercial fee: In the world of nuclear engineering, health physics,

Finding a free download for isn't as simple as clicking a link on a software site. Because it’s a powerful tool used in nuclear design, medical physics, and radiation protection, its distribution is strictly controlled by the U.S. government.

: If you are a student in a relevant field (like Nuclear Engineering), your university may already have a site license. Some university courses provide the MCNP6 Monte Carlo code package to students at no cost through the Radiation Safety Information Computational Center (RSICC) . However, there are two ways to get it

A general-purpose tool widely used in Japan and Europe for heavy ion therapy and space research.
