Efforts during the January through March 1978 quarter were directed towards the evaluation of MHD electrodes for both clean and coal fired environments. Electrochemical screening tests in simulated liquid slags have continued, and provide additional information on the chemistry, mechanisms, and kinetics of electrode/slag reactions. U-02 Proof Test 3 was completed in early January. A post-test evaluation was made and the results compared with those of the previous 2 proof tests. Post-test materials characterization, including efforts at National Bureau of Standards (NBS) and Battelle Pacific Northwest Laboratories (BNW), was completed and provided the basis for the selection of LaCrO/sub 3/- based electrode materials with compliant Ni-mesh attachments for the U-02 Phase III electrode walls. Materials development and detail design activities in support of the U-02 Phase III module continued, and U-02 Phase III electrode sub-assemblies were prepared.
