Abstract
The 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, the addition of a more complete set of gamma production data, and the 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 nuclear data library benchmarking effort and an overview of other HELIOS2 development efforts.
Kurzfassung
Die fortlaufende Weiterentwicklung des Programms HELIOS2 bei Studsvik beinhaltet periodische Updates der nuklearen Datenbibliothek. Die aktuelle Erweiterung umfasst eine Aktualisierung der Wirkungsquerschnittsbibliothek auf ENDF/B-VIIR1, eine größere Erweiterung der Abbrandketten, eine Erweiterung des Sets der Gammaproduktionsdaten und die Entwicklung einer neuen Option zur Resonanzbehandlung. Das Ziel dieser Erweiterung ist es, sowohl das Anwendungsgebiet von HELIOS2 als auch die Kopplung mit SNF, dem Studvisk Spent Fuel Code zu erweitern und zu verbessern. Dieser Beitrag enthält zusätzlich auch eine Beschreibung der Vorarbeiten zur Teilnahme am nuklearen Datenbibliothek-Benchmark UAM-LWR als auch einen Überblick über weitere Entwicklungsschritte des Programms.
