The purpose of the study presented in this report was to define the modifications required to the 1-MW/sub th/ solar cavity steam generator system to permit its testing in the 5-MW Thermal Solar Test Facility at the Sandia Laboratories, Albuquerque, New Mexico. Analyses were performed to evaluate solar flux intensities and energy distributions within the receiver cavity when exposed to the concentrated solar flux reflected by the 78 heliostats in the collector field. These analyses indicated that it was feasible to decrease absorbed flux intensity and distribute properly the solar energy within the cavity by coating with white paint selected regions of the boiler and superheater. A preliminary investigation of the receiver start-up sequence at the test facility was made. Additional instrumentation for the test was identified and the need to replace the feedwater heater/desuperheater flow control valves was established. A preliminary design of the receiver modifications was performed. This includes an insulated door for the receiver aperture and a protective system designed to absorb the energy around the receiver aperture and provide a means to quickly intercept the solar flux during flux measurements and emergencies. Installation of the 1-MW/sub th/ receiver system at the test facility tower was investigated and a preliminary layout of the equipment was made.
