A nuclear power plant (NPP) is a highly complex system-of-systems as manifested through its internalsystems interdependence. The negative impact of such interdependence was demonstrated through the2011 Fukushima Daiichi nuclear disaster. As such, there is a critical need for new strategies to overcomethe limitations of current risk assessment techniques (e.g. the use of static event and fault tree schemes),particularly through simulation of the nonlinear dynamic feedback mechanisms between the differentNPP systems/components. As the first and key step towards developing an integrated NPP dynamicprobabilistic risk assessment platform that can account for such feedback mechanisms, the current studyadopts a system dynamics simulation approach to model the thermal dynamic processes in: the reactorcore; the secondary coolant system; and the pressurized water reactor. The reactor core and secondarycoolant system parameters used to develop system dynamics models are based on those of the PaloVerde Nuclear Generating Station. These three system dynamics models are subsequently validated,using results from published work, under different system perturbations including the change in reactivity,the steam valve coefficient, the primary coolant flow, and others. Moving forward, the developedsystem dynamics models can be integrated with other interacting processes within a NPP to form thebasis of a dynamic system-level (systemic) risk assessment tool
