Step-by-Step: How to Apply for MCNP6.2 via RSICC

1. Visit the RSICC website (rsicc.ornl.gov).
2. Create an account using your institutional email (.edu or .gov).
3. Search for "MCNP6.2" in the software catalog.
4. Submit the required forms:
   • Export Control acknowledgment
   • End-User License Agreement (EULA)
   • Letter of intent on institutional letterhead (for first-time applicants)
5. Pay the administrative fee (if applicable).
6. Wait for approval (typically 2–4 weeks for international users, 1 week for U.S. academic users).
7. Download officially via encrypted FTP or receive a USB drive.

3. Legal and Regulatory Framework

The reason MCNP6.2 is not open-source or freeware is rooted in U.S. national security interests.

Typical use cases and user profile

• Users include criticality safety analysts, radiation-shielding engineers, medical physicists, detector designers, and academic researchers.
• Institutions performing regulated nuclear work or with contractors subject to export control most commonly obtain MCNP through RSICC.
• Classroom use is supported; instructors can obtain packages for students but should follow RSICC guidance to accelerate approvals.
