The Radiation Safety Information Computational Center (RSICC)

Can I take that shipment through Nevada?

The regulations governing shipment of nuclear medicine sources are complex. The Radiation Safety Information Computational Center (RSICC) provides web-based access to the nuclear codes needed to calculate appropriate shielding for such shipments.

For the past three decades the Radiation Safety Information Computational Center (RSICC), has served as the official Department Of Energy (DOE) repository for nuclear computer codes and data, collecting and disseminating related information worldwide under specific distribution restrictions and guidelines set by U.S. government. In fulfilling its mission, RSICC constantly kept pace with the breathtaking evolution of all aspects of computer software and hardware. CENTS is designed to initiate the transformation of RSICC into a DOE computational center for the new, information-based century. The impact of this endeavor will be felt in all projects that contain a heavy computational component and will bring the latest developments in computer and computational sciences closer to a wider base in the users community.

The Collaborative Environment for Nuclear Technology Software (CENTS) aims to lay the foundation for a Web-based distance computing facility for executing nuclear engineering codes. Through its Web-based interfaces, CENTS will allow users to focus on the problem to be solved instead of the specifics of a particular nuclear code. Both parallel (two similar codes operating on the same data) and serial (one code feeding another) integration of nuclear codes will be supported. Via the Web, users will submit input data with computing options for execution, monitor the status of their submissions, retrieve calculational results, and use CENTS tools for viewing and analyzing result data. Stronger-than-password security mechanisms will prevent unauthorized access to computing resources and ensure a user's input and output data are not compromised. For computational services, CENTS will employ a collection of heterogeneous computer systems logically clustered and managed for optimal resource utilization. The CENTS architecture will employ Java mobile agents for problem description and submission in a Web-based environment. Moreover, CENTS will be constructed in a modular, open-ended style in order to address immediate needs of DOE and the nuclear community while accommodating future expansion due to yet unforeseen demands and advances in computer architecture and network capabilities.
