: Go to the RSICC Website to browse their software catalog.
: The official LA-UR-17-29981 report details the math, geometry, and input structures for version 6.2.
If you want, I can tailor this post for a specific audience (academic, industrial, or beginner), add terminal commands for a particular OS, or produce social-media-sized versions (Twitter/LinkedIn).
Released officially in February 2018, this version introduced significant improvements over earlier versions:
Go to the official RSICC website ( rsicc.ornl.gov ) and locate the request form for the MCNP6.2 code package (RSICC CODE PACKAGE CCC-850). You will need to:
Provide accurate details about your university, company, or research institution.
Review the MCNP Version 6.2 Release Technical Report for step-by-step instructions on the script-based installation process and system requirements. User's Manual Code Version 6.2 - MCNP
To legally acquire the software, you must request it through authorized distribution centers: RSICC (Radiation Safety Information Computational Center): Most users worldwide obtain MCNP from the RSICC website
Version 6.2 features improved support for unstructured meshes generated via CAD software, allowing users to import highly intricate mechanical designs directly into the simulation.
Once you successfully complete the RSICC or OECD-NEA process, here is what your "MCNP 62 download" will include:
MCNP (Monte Carlo N-Particle) Version 6.2, released in early 2018, is a major milestone in radiation transport code developed by the Los Alamos National Laboratory (LANL) .
MCNP® (Monte Carlo N-Particle) is the cornerstone of nuclear modeling and radiation transport analysis. As of 2026, remains a critical release for professionals in nuclear engineering, health physics, shielding design, and reactor physics, offering enhanced capabilities for tracking particles over broad energy ranges. Finding the top, legitimate, and fully supported method to download this software is vital for ensuring accurate simulations.
