Level 2 PSA could give us the quantitative results of large release frequency (LRF), containment response and source terms. Moreover, it is essential for the demonstration on safety goals and Emergency Plan Zone (EPZ). ACP100 is an integrated SMR design developed by China, which adapts the advanced passive safety system and innovative design philosophy. In this study, it is focused on the study of ACP100 full-scope Level 2 PSA, which consists of internal and external events, as well as full power, low power and shutdown conditions. In this study, firstly, it will introduce the related requirements and ACP100 design features related to severe accident phenomenon and management. Secondly, it will summarize some key techniques of ACP100 full-scope Level 2 PSA study process. Finally, it will analyze the internal flood Level 2 PSA study case as an example with conservative assumptions, discuss the conclusion and outlook.
