The results of the General Atomic (GA) fixed-mirror solar concentrator (FMSC) concrete panel development program are presented. The FMSC is part of the solar steam supply system proposed by GA for the SolarOil project. The program was conducted to determine the achievable accuracy of precast concrete concentrator panels and to investigate expedient and economical mass production of the panels. One steel form, two concrete forms, and three concrete panels were fabricated and about 1500 slat angle measurements made using a laser inspection fixture developed expressly for this purpose. All panels were 1.83 m (6 ft) long and had a 3.6 m (11 ft 10 in.) aperture and 71 slats. Proper concrete mixes, parting compounds, placement methods, vibrating techniques, and curing procedures were identified, and the hardware and techniques for stripping and turning the panels were tested. Based upon test results and structural calculations it was concluded that reasonably priced 5.5-m (18 ft) long panels can be produced with either steel or fiberglass-coated concrete forms with 95% to 99% of the slat area within +-0.25/sup 0/ of the desired angles. With steam curing, the production rate is one panel every other working day per 5.5 m (18 ft) of form length.
