Title: Liquid Metal Compatibility Issues for Test Blanket Modules

Abstract

Liquid metal compatibility issues are being investigated for two different test blanket modules involving either Li or Pb-17 at.%Li. A solution to the magnetohydrodynamic (MHD) problem for the V-Li concept may be attainable using multi-layer coatings or a flow channel insert with vanadium in contact with the flowing Li instead of a ceramic insulating layer. These strategies rely on the expected excellent compatibility of vanadium alloys which is being further investigated. For systems using Pb-17Li, capsule testing of SiC and various alloys is being conducted. Monolithic SiC specimens exposed for 1000 h in Pb-Li at 800 and 1100 {sup o}C showed no mass change after cleaning and no detectable increase in the Si content of the Pb-Li after the test. In order to investigate the behavior of corrosion resistant aluminide coatings, initial capsule testing at 700 {sup o}C has been used to establish baseline dissolution rates for 316 stainless steel, FeCrAl, Fe{sub 3}Al and NiAl. The samples containing Al showed significantly less mass loss than 316 stainless steel, suggesting that aluminide coatings will be beneficial in this temperature range.
