Sandia National Laboratories is a multimission laboratory managed and operated by National Technology and Engineering Solutions of Sandia, LLC, a wholly owned subsidiary of Honeywell International, Inc., for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-NA0003525. This paper presents a new graphical user interface and workflow management capability to perform uncertainty quantification on a variety of nuclear reactor codes using Dakota. The graphical user interface, input file creation and parsing, input validation, job execution, workflow management, and output postprocessingisprovided by a new tool called the NEAMS Workbench [1].
