A fused cast spinel, MgAl/sub 2/O/sub 4/, has been evaluated for its corrosion resistance in western slag. The spinel appears to be insignificantly affected by the corrosive nature of the slag and based on this performance will be subjected to further testing. Results of thermal conductivity measurements of a number of hafnia and zirconia based electrode materials, to be run in the upcoming WESTF Test 42, are reported. Laboratory electrochemical screening tests have continued. Results are presented for iron cathodes and platinum anodes in western slag. Results from additional electrochemical polarization tests have shown the desirability of modifying the test cell to improve test reproducibility. A summary of available data covering electrode durability has been prepared covering laboratory electrochemical and generator tests for various MHD environments. Emphasis has been placed in refractory electrode materials. The status of various design activities, including design of the Materials Test Section (MTS), the modified WESTF test section, and various WESTF test design activities, are presented. Results of post-test analysis activities for WESTF Test 41 - Run 2 and WESTF Test D-9 are presented.
