Description

This study aims to assess the void fraction predictability of three different system codes, TRACE V5.0 Patch 5, MARS-KS 1.4, and RELAP5/MOD3.3 Patch 5. The assessment has been conducted against the experimental data from OCED/NRC PSBT (PWR Subchannel and Bundle Test) benchmark. The test cases under steady-state conditions with subchannel and bundle geometries have been selected to the evaluation. The void fraction predictability of the system codes, TRACE, MARS-KS, and RELAP5, have been assessed against experimental results from OECD/NRC PSBT benchmark. The calculated results for single channel cases indicate that all the system codes systematically overpredict the void fraction in low void conditions, and the overprediction tendency could be also identified in bundle cases whereas in high void condition the prediction lies within 2σ. The statistical investigation confirms that TRACE results in higher prediction error compared to MARS-KS and RELAP5. The overprediction tendency is confirmed clearly for under 30% void fraction condition.
