The paper reports on a benchmarking activity carried on within the frame of the IAEA CRP on “Heat Transfer Behaviour and Thermo-hydraulics Codes Testing for SCWRs”, aimed at comparing the results of linear and non-linear codes and models in the application to a simple reference geometrical condition. The simplicity of the proposed problem was conceived to allow for the application of one- dimensional models. The results of the analyses were reported in dimensionless form, adopting recently proposed definitions in order to check their suitability to represent stability thresholds. Both dynamic and static instabilities were addressed. The paper presents the results of this benchmark exercise as well as the preliminary conclusions.

Abstract
The paper reports on a benchmarking activity carried on within the frame of the IAEA CRP on “Heat Transfer Behaviour and Thermo-hydraulics Codes Testing for SCWRs”, aimed at comparing the results of linear and non-linear codes and models in the application to a simple reference geometrical condition. The simplicity of the proposed problem was conceived to allow for the application of one- dimensional models. The results of the analyses were reported in dimensionless form, adopting recently proposed definitions in order to check their suitability to represent stability thresholds. Both dynamic and static instabilities were addressed. The paper presents the results of this benchmark exercise as well as the preliminary conclusions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
