Abstract
The application of the current version of the Relap5 code to the experiment B-302 performed in LOBI test facility is discussed in this report. LOBI was a Pressurized Water Reactor (PWR), simulator of German 4-loop KWU-Siemens reactor, installed in the EC center of Ispra Italy supported by EURATOM. A1-82 is a Small Break Loss of Coolant Accident (SBLOCA) experiment part of the A-matrix of tests originally available only to German scientists.. The activity targets are: a) Further code validation – assessment b) Expanding the database of code application also in view of adopting the accuracy for UMAE and (later-on) CIAU uncertainty method application c) Training of scientists. The validation activity is performed by adopting the latest available techniques and procedures developed at UNIPI including nodalization qualification, use of acceptability thresholds and qualitative and quantitative evaluation of accuracy. Furthermore the activity (A-Test analysis) took benefit from the release by the German government of all details of the design of the LOBI facilityI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
