Sandia Laboratories materials task group review of the advanced central receiver preliminary designs. I, molten salt and liquid metal

ABSTRACT:
Potential materials problems associated with the preliminary designs for liquid sodium and molten salt advanced central receivers are identified and recommendations suggested. Appendices which detail generic sodium materials issues and selected bibliographies on each fluid have been

included. Liquid sodium systems are well defined technically, and code certified materials exist. Large components for power plant applications have been developed and tested. Molten nitrate salt systems, while used frequently in process industries, do not have an extensive user history at typical power plant steam temperatures. Significant development and testing will be required to achieve a materials data base comparable to that for water-steam and sodium technologies. At present, no unsolvable materials issues are apparent, however a wide variety of question need to be resolved before design can be committed to a power plant.
