Validation and Application of TRACE for Transient Analysis of a German BWR Plant

Abstract

The Karlsruhe Institute of Technology (KIT) is participating on CAMP to validate TRACE for LWR transient analysis. The validation of safety-relevant heat transfer models of TRACE, data BFBT bundle tests are available for institutions taking part on international OECD/NEA Benchmarks. In the first step, the BWR-relevant models of TRACE were validated using experimental data. Then, an integral plant model of a German BWR of Type-72 was developed using the multidimensional VESSEL- component of TRACE to simulate a plant events such as the TUSA. In this paper, the validation work, the plant modeling and selected results will be presented and discussed.
