The article presents a preliminary risk analysis of the main features in NPP (Nuclear Power Plant) that includes SMR - Small and Modular Reactors, given an extreme threat scenario. A review of the structure and systems of the SMR is followed by systematic definitions and analysis of the threat scenario to which a preliminary risk analysis was carried out. The article outlines the basic events caused by the referred threat scenario, which had led to (1) possible failure mechanisms according to FTA (Fault-Tree-Analysis), (2) critical protective circuits, and to (3) detecting critical topics for the protection and safety of the reactor.
