CRS instrumentation review

A number of specific problems relevant to the central receiver system instrumentation as it is foreseen are surveyed with the aim of determining if the foreseen instrumentation is adequate to determine the technical performance of the plant. The choice of relevant operational characteristics is analyzed, and the given instrumentation for the efficiency calculations are assessed. The efficiency accuracy before and after calibration of the given instrumentation is estimated and the proposed calibration procedure is given. Critical parts, proposed measuring methods and measuring points are identified for thermal losses. Finally, the transients during normal operation conditions are considered. (LEW)
