Innovative Nuclear Power Plants (NPPs) resort to passive systems to increase their safety and reliability. However, during accidental scenarios, uncertainties affect the actual behavior of passive systems. In this paper, a systematic procedure based on the Analytic Hierarchy Process (AHP) for the identification of the uncertain parameters and the propagation of their associated uncertainties is proposed. An example of application is proposed with respect to the passive Residual Heat Removal system (RHRs) of the High Temperature Reactor-Pebble Modular (HTR-PM).
