%0Computer Program %Tfudge %XFUDGEFudge provides (Python based) tools to: • Store and modify nuclear data. • Convert ENDF-6 formatted nuclear data [1] into Generalized Nuclear Data (GND) structure [2]. • Convert LLNL’s ENDL formatted nuclear data [3] into GND. • Plot data from GND files. • Check for physics problems in GND files. • Process nuclear data for use by Monte Carlo and/or deterministic codes. Fudge contains hooks for the future addition of nuclear data processing routines. The Fudge release includes samples of published ENDF-6 formatted data that can be converted to the new GND format. This software is the next release in a series of releases that began with GND version 0.1 [2]. %ARomano, Paul %AHedstrom, Gerry %ASummers, Neil %APatel, Nidhi %AJugenson, Eric %AThompson, Ian %Rhttps://doi.org/10.11578/dc.20190715.2 %Uhttps://www.osti.gov/doecode/biblio/27756 %CUnited States %D2015 %GEnglish %2USDOE National Nuclear Security Administration (NNSA) %1AC52-07NA27344 2015-12-01
