Abstract


In order to quantitatively analyze the maneuverability of ship nuclear power system, based on the working principle of UTSG, a modularized lumped parameter model was established based on the one-dimensional simplification of the working fluid by the homogeneous flow model. The modularized lumped parametric model is used as a tool to study the operating characteristics of UTSG. Through the analysis of the coolant flow rate disturbance and the feed water flow rate disturbance, we show the change rules of the operation parameters of UTSG. The research results can provide a basis for the maneuverability analysis of the ship nuclear power system.
