The distribution of SCALE to end-users is subject to US export control regulations, and each user must be individually licensed through an authorized distribution center. SCALE licenses are issued through the Radiation Safety Information Computational Center (RSICC) at ORNL and the Research Organization for Information Science and Technology (RIST) Nuclear Code Information Services (NUCIS) in Japan. Any license fees collected for the distribution of SCALE are retained by these organizations to offset the costs of background checks and media duplication, and no part of the license revenue is used to support SCALE activities.
