Application of the Interface Between Dakota and the Argonne Reactor Computation Codes in the NEAMS Workbench

摘要

The NEAMS Workbench provides a common user interface for model creation, which can allow for its integrated codes to communicate and work together. In particular, this paper illustrates how the Workbench can be utilized for solving SA/UQ problems in a Sodium-cooled Fast Reactor with integrated codes Dakota and PERSENT. Using the Dakota code through the Workbench extends the SA/UQ capability currently available in the ARC codes to propagate the uncertainty on any type of input parameter, and to observe its impact on any output result. Future work should take advantage of the optimization toolkit available with Dakota to drive design studies with the ARC code.
