This program is directed towards the engineering development of cold metallic electrodes which are alternatives to the use of platinum as an anode clad material for MHD generators. Results of continuing laboratory screening tests are presented. Improvements in the anode arc test methodology and test setup, which have resulted in improved reproducibility as well as test simplification, are discussed. Laboratory electrochemical corrosion testing has been initiated using aqueous and molten salts as the aggressive constituent in the electrolyte. Initial results from these tests are reported. On the basis of these test results, electrochemical corrosion tests using a molten salt are preferred. As a result of ongoing laboratory screening tests, acceptance criteria, which are interim in nature and are likely to change based on future test results have been defined for the anode arc and electrochemical corrosion tests. Reflecting the initial laboratory test results, a listing of candidate advanced alloys which should demonstrate improved corrosion resistance has been defined. Upon completion of WESTF modifications, facility checkout and activation operations have been initiated. Progress, as well as those difficulties which have been encountered, in completing WESTF activation is reported. Detailed engineering and test planning activities in support of WESTF tests are reported.
