Abstract
Besides the final efficiency, the most crucial factor of an energy conversion system for propulsion purposes is the total mass or size of the system. Considering that, this paper aims the development of a design-based model which predicts the thermodynamic performance of a Rankine cycle applied in a Pressurized Water Reactor (PWR) nuclear plant. The endoreversible model considers the thermal conductance of the main components in order to predict the energy conversion performance, allowing its use as preliminary tool for the heat exchanger optimization. The centrifugal-flow turbine and pump characterization were achieved using isentropic efficiencies. Moreover, an optimization analysis based on the final area/size of these components is performed. Based on the proposed endoreversible model, efficiency or size optimization can be achieved with a proper reallocation of thermal conductance related to the components steam generator and condenser.
