NEA-1454 ZZ-BWRSB-RINGHALS1&2

1. NAME OR DESIGNATION OF PROGRAM:  ZZ-BWRSB-RINGHALS1&2

3. DESCRIPTION OF PROGRAM OR FUNCTION

The purpose of this benchmark is to enable code developers to test their codes and also to validate the predictive capability of their respective codes and models for BWR stability analysis. Emphasis is put on the modeling of flow dynamics of the reactor core and in-vessel flow loop wit detailed neutronic and thermodynamic feedback. The secondary systems as well as the control and production systems will be neglected. Data provided comes from measurements in beginning of cycle (BOC) 14, 15, 16 and 17 and middle of cycle (MOC) 16 in the Swedish BWR reactor Ringhals 1. For these measurements complete data sets are given.
