The U.S. Nuclear Regulatory Commission (NRC) has, over the years, developed numerous radiation protection, dose assessment, and emergency response computer codes. These codes are used by NRC staff, other U.S. federal agencies, NRC’s Agreement States, licensees, researchers, and international partners.
RAMP was established as an integrated NRC program to prioritize, maintain, and update all of the NRC’s radiation protection codes, control distribution of the codes to users outside of the NRC, and maintain user forums in which users may discuss the use of the codes and seek answers to specific problems that they may encounter with the codes.
The RAMP user group has over 5,000 active members and partners across 50+ countries. RAMP has had over 10,000 code users across the history of the program.
There is a free membership tier, and most codes are free for most users. Read more on user types below.
Why Join?
RAMP membership provides access to:
- The latest code releases.
- Upcoming international and domestic user meetings, to share experiences and discuss code development.
- Past user group meeting and code-specific training recordings and documentation.
- Technical basis documents and user guidelines for applying the codes.
Register
To gain access to RAMP codes, please follow the step-by-step NDA Instructions for RAMP registration. Most codes are free for most users. At a high level, if you are interested in RASCAL, SNAP/RADTRAD, or IMBA, you may read more on user types below or check out our Premium Codes page to determine if you must pay for access. If you are interested in any other RAMP codes, they are free and you will just have to fill out or sign onto an NDA.
Note, CAP88, RESRAD, Turbo FRMAC, and VSP are RAMP-affiliated and joint-sponsored codes that RAMP supports but does not distribute. Their individual code pages will take you to the non-NRC institutional sites (EPA, Argonne, Sandia, and PNNL, respectively) where you can apply to acquire them.
Domestic User
For NRC Staff, you have streamlined access to RAMP codes in a process separate from the external user RAMP website. Email RAMP@NRC.gov and list what codes you need to learn more.
Are you a government contractor, licensee, and/or for-profit organization based in the United States? If so, most codes are free for you. Premium codes, IMBA, RASCAL, and SNAP/RADTRAD have associated costs, unless you pursue a VIP membership.
