Analytical Investigation of APR1400 SBLOCA Using MARS-KS Code

  • 1. Korea Institute of Nuclear Safety, Daejeon (Korea, Republic of)

Description

The possibility of core uncovery and significant reheat due to loop seal clearing and reformation phenomena was considered as one of the safety issues by USNRC in the review of design certificate for APR1400. Therefore, it is needed to perform the independent audit calculation to review the results of safety analysis on APR1400 SBLOCA with changed codes and the raised issue explained above. In this study, the transient behavior of APR1400 SBLOCA was analyzed with MARS-KS code. The thermal-hydraulic phenomena including loop seal clearance and reformation was observed so that its effect on core cooling capability and safety margin were identified.
