The objective of the Phase II Alternate Central Receiver program was to demonstrate the feasibility of the molten salt central receiver power system by conducting a series of experiments and using the results to update the commercial-scale design developed during Phase I of the program. The experiments were directed at two levels of inquiry: the systems-level testing of a 5 MW/sub th/ molten salt receiver - hereafter referred to as the receiver SRE; and the investigation of molten salt chemistry and the compatibility of selected materials with molten salt. Detailed discussion of the receiver testing are contained in Volume II of this report, while the materials tests are the subject of this volume. The materials and salt chemistry research experiments were designed to answer important questions on the use of molten salt mixtures of sodium and potassium nitrate in solar receiver applications. The experiments were conducted to provide data in the areas of molten salt stability and materials compatibility which could be used in designing a commercial molten salt solar central receiver power system with a lifetime of 30 years or more. Four different categories of tests were conducted: (1) materials compatibility; (2) materials mechanical properties; (3) dynamic testing; and (4) salt chemistry tests.
