Work on the evaluation of MHD electrodes for both clean fuel and coal fired environments is reported. Electrochemical screening tests in an eastern slag have continued and are summarized. The chemistry, mechanisms and kinetics of electrode/slag reactions have been evaluated. Important electrochemical reactions include: slag electrolysis, preferential transfer of aggressive ion species in the slag to the cathodes and anodes, chemical reactions of electrodes with slag and with the products of the electrolysis of the slag, and cavitation/erosion of the anodes. Materials development and detail design activities in support of the U-02 Proof Test Series is continuing. Fabrication and assembly has been completed for each of the three test assemblies for the Proof Test Series. Proof Test 1 (WESTF Test 38) and Proof Test 2 (WESTF Test 39) were completed in October and November, respectively. Post-test evaluation of these runs in continuing; facility and thermal analyses have been completed. Post-test material characterization is cntinuing, including efforts at National Bureau of Standards (NBS) and Battelle Pacific Northwest Laboratories (BNW).
