GDSA framework, a computational framework for complex modeling problems in radioactive waste management

Portone, Teresa; Swiler, Laura P.; Eckert, Aubrey; Basurto, Eduardo; Friedman-Hill, Ernest

This paper details a computational framework to produce automated, graphical workflows, and how this framework can be deployed to support complex modeling problems like those in nuclear engineering. Key benefits of the framework include: automating previously manual workflows; intuitive construction and communication of workflows through a graphical interface; and automated file transfer and handling for workflows deployed across heterogeneous computing resources. This paper demonstrates the framework's application to probabilistic post-closure performance assessment of systems for deep geologic disposal of nuclear waste. However, the framework is a general capability that can help users running a variety of computational studies.
