Description
Evaluated Means and Uncertainties, or EMU, is a new suite of tools for generating statistical realizations of nuclear data libraries encoded in the Generalized Nuclear Database Structure (GNDS). Built upon the For Updating Data and Generating Evaluations (FUDGE) package from LLNL, EMU is capable of reading and generating realizations of nearly any accessible nuclear data library, whether they originate in ENDL, ENDF, of GNDS formats. EMU was developed with two run modes; a traditional command line interface that creates realized GNDS files for a reaction, and a “sample map” mode that can automate large scale uncertainty quantification involving many different materials and even different libraries. This sample map mode can also automate the processing of GNDS files so that reactions at the different temperatures and groupings are correctly related to each other within the realization. I will review the general structure of EMU and what makes it unique, and give an overview of how it can easily integrate into other uncertainty quantification workflows.
