Conceptual design of advanced central receiver power system, phase I. Executive summary
The conceputal design is briefly described of a 300 MWe molten salt-based central receiver power plant with sufficient heliostats and storage capacity to provide full load operation 24 hours per day at summer solstice. The collector, tower, electric power generation, cavity receiver, molten salt handling equipment, heat exchangers, thermal storage, and master control subsystems are described, and parametric analyses of the subsystems are discussed. An assessment of the recommended system is discussed which includes detailed cost analysis, an economic analysis to compute the bus bar electricity cost, potential for future improvements, definition of possible limitations to the application of the system, and the value of thermal storage. Results of a comprehensive test program are summarized that includes long-term high-temperature stability, basic molten salt chemistry, materials compatibility, and fluid loop testing. A development plan is described, including the conceptual design and cost estimate of a pilot plant, research experiments, development schedule, and a description of an alternative 100-MW plant for comparison. Also an analysis of an alternative system using an exposed receiver rather than a cavity receiver is summarized. (LEW)
