improved so that the plant currently performs as originally intended. The items that brought about the improved operation include a new control system, a steam superheater, a larger boiler tube sheet, and a pressurized expansion tank for the heat transfer fluid. The aluminized film on five solar collectors was replaced with silvered film to improve the reflectivity and to field test its survivability.
