Post-Test Simulation on a VISTA-ITL Integral Effect Test Using the MARS-KS Code for the SMART Design

摘要

A post-test simulation on a SBLOCA test for a PSV line break (SB-PSV-02) has been performed with the MARS-KS code to assess its simulation capability for the SBLOCA scenario of the SMART design. The SBLOCA scenario in the SMART design was well reproduced using the VISTA-ITL facility, which has a reduced-height, 1/1310-volume scaled test facility based on the design features of SMART, and the measured thermal-hydraulic data were properly simulated with the MARS-KS code. The present analysis results on SBLOCA can provide a good understanding on the thermal-hydraulic characteristics of the SBLOCA behavior of the SMART design.
