ADVANCES IN HELIOS2 NUCLEAR DATA LIBRARYCharles Wemple, Teo Simeonov Studsvik Scandpower Inc. charles.wemple@studsvik.com teodosi.simeonov@studsvik.comABSTRACTThe ongoing development of the HELIOS2 code system at Studsvik includes periodic updates of the nuclear data library. The library expansion includes an update of the cross section data source to ENDF/B-VIIR1, a significant expansion of the burnup chains, addition of a more complete set of gamma production data, and development of new resonance treatment options. The goal is to provide the capability for HELIOS2 to more accurately model a wider array of reactor applications and enhance interoperability with SNF, the Studsvik spent fuel analysis code. This paper will also provide a discussion of the benchmarking effort and an overview of other HELIOS2 development efforts.KEYWORDS: nuclear data library, cross sections, burnup, ENDF/B-VII, HELIOS, SNF 26th Symposium of AER on VVER Reactor Physics and Reactor Safety 2 10 – 14 October 2016, Helsinki, Finland
