The steam turbine installations in nuclear power units are of the condensation type. The main parameters affecting the performance of condensation-type steam turbine installations are the steam flow rate at the turbine inlet, the temperature variation, and the flow rate of cooling water entering the condenser. Any change in these parameters directly influences the amount of electrical energy produced by the steam turbine. To study their influence, it is necessary to collect a large amount of data and synthesize a mathematical model. Data collection through measuring and recording equipment is a complex, time-consuming process associated with both the technological time required for gathering and subsequent processing. Simulation modeling is a modern research tool that allows studying energy systems without disrupting the technological process. This modeling involves developing an analogue of an existing object in a graphical software environment where geometric and physical parameters characterizing the object’s properties are defined. The results obtained from solving the simulation model must be compared with data from characteristic operating modes of the examined object. The present paper aims to develop a simulation model for assessing the performance of a condensation-type steam turbine installation of a nuclear power unit model K-1000-60/1500-2. This steam turbine installation is typical for nuclear power units of the VVER-1000 type. The data obtained from the simulation model will be used to construct a mathematical model determining the parameters characterizing the operation of the condensation steam turbine installation.
