SMART Station Blackout Analysis

The Fukushima accident represents the latest fear of any nuclear industry whether established or just starting. Although it was a natural disaster, it must be assured that even under such circumstances, radioactive material is contained and release is avoided. Despite the possibility of radioactive release occurring over multiple consequences, such scenarios must be considered. The Fukushima scenario is considered in the SMART (System Integrated Modular Advanced Reactor) design with the availability and loss of the Passive Residual Heat Removal System (PRHRS). Using the Multi-dimensional Analysis of Reactor Safety (MARS) code, this paper presents the Fukushima scenario studies along with the calculated grace time as results. The results of SMART Station Black Out (SBO) analysis show grace time of almost two and a half days for the worst-case scenario
