: Every request undergoes a review process. You must provide details about your intended use and institutional affiliation to ensure compliance with U.S. export laws.
There are three critical reasons for this restriction:
You must state exactly what you are simulating (e.g., medical physics, aerospace shielding, academic education). Applications involving proliferation-sensitive technologies are denied.

In summary, while MCNP6.2 is a powerful industry-standard tool, there is no "free download" in the casual sense. The only legitimate path is through the official, controlled distribution process managed by the RSICC.
What you are running (e.g., shielding, criticality, dosimetry)?

If you work in nuclear engineering, health physics, or radiation shielding, you have likely heard of (Monte Carlo N-particle). It is the gold standard for radiation transport simulation. Consequently, one of the most common search terms in this field is "MCNP6.2 download free." There are three critical reasons for this restriction:
It is widely used for reactor core modeling and generation of homogenized multi-group constants.
While you must purchase a license for the full version, the software is provided at for government, educational, or research institutions that qualify. However, it requires a formal request and export control review. Steps to Download MCNP6.2 via RSICC
