The high-temperature gas-cooled reactor is a promising concept for inherently safe nuclear power generation. This article deals with dynamic modeling of a combined heat and power plant, based on a helium-cooled reactor in combination with a closed-cycle gas turbine system. A one-dimensional flow model describing the helium flow and the two-phase water flow is used through the whole plant, with different source terms in different pieces of equipment. A stage-by-stage model is produced for the radial compressor and axial turbine. Other models include the recuperator, water/helium heat exchangers, a natural convection evaporator, valves, etc. In Part II the model will be used to analyze the dynamic behavior and to design a control system.
