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.

Compatibility Issues for a High Temperature Dual Coolant Blanket

Conference Pint, Bruce

One proposed U.S. test blanket module (TBM) for ITER uses ferritic-martensitic alloys with both eutectic Pb-Li and He coolants at {approx}475 C. In order for this blanket concept to operate at higher temperatures ({approx}750 C) for a DEMO-type reactor, several Pb-Li compatibility issues need to be addressed. A SiC/SiC composite flow channel insert is proposed to reduce the steel dissolution rate (and the magnetohydrodynamic pressure drop). Prior capsule testing examined dense, high-purity SiC in Pb-Li at 800-1200 C and found detectable levels of Si in the Pb-Li after 2,000h at 1100 C and 1,000h at 1200 C.

Recent Progress Addressing Compatibility Issues Relevant to Fusion Environments

Journal Article Pint, B; More, K; Meyer, H; ... - Fusion Science and Technology

Current compatibility research in the U.S. focuses on two topics: dual- or multi-layer electrically-resistant Y{sub 2}O{sub 3}/vanadium coatings in a V-Li blanket concept and SiC composites with a Pb-Li coolant. The compatibility issue for multi-layer coatings includes the ceramic insulating layer and the metallic vanadium alloy layer. Characterization of Y{sub 2}O{sub 3} coatings after exposure to Li shows significant changes in the microstructure. Initial static capsule results for V-4Cr-4Ti alloys in Li at 800 deg. C showed unexpected small mass gains. Capsule tests of monolithic SiC in Pb-17Li showed no mass change and no wetting after 1000h at 800 deg.more »« less
Evaluation of Pb-17Li compatibility of ODS Fe-12Cr-5Al alloys

Journal Article Unocic, Kinga; Hoelzer, David - Journal of Nuclear Materials

The Dual Coolant Lead Lithium (DCLL: eutectic Pb–17Li and He) blanket concept requires improved Pb–17Li compatibility with ferritic steels in order to demonstrate acceptable performance in fusion reactors. As an initial step, static Pb-17at.%Li (Pb-17Li) capsule experiments were conducted on new oxide dispersion strengthened (ODS) FeCrAl alloys ((1) Y₂O₃ (125Y), (2) Y₂O₃+ZrO₂ (125YZ), (3) Y₂O₃+HfO₂ (125YH), and (4) Y₂O₃+TiO₂ (125YT)) produced at ORNL via mechanical alloying (MA). Tests were conducted in static Pb–17Li for 1000 h at 700°C. Alloys showed promising compatibility with Pb–17Li with small mass change after testing for 125YZ, 125YH and 125YT, while the 125Y alloy experiencedmore »« less

Material Compatibility with Isothermal Pb-Li

Conference Pint, Bruce; Walker, Larry; Unocic, Kinga

Eutectic Pb-Li is a leading candidate for current fusion blanket concepts as a coolant. However, there is very little data about the compatibility of most materials with Pb-Li above 500 C where the dissolution rate of many conventional alloys increases rapidly. Current work is beginning to assess Pb-Li compatibility from 500 to 800 C using isothermal capsule experiments. Aluminide coatings hold some promise in protecting conventional Fe-base alloys at 600-700 C. However, there is a significant initial Al loss that has not been clearly explained. Furthermore, the reaction product with coated materials is LiAlO{sub 2} rather than Al{sub 2}O{sub 3}more »« less
Development of electrical insulator coatings for liquid-metal blanket applications

Technical Report Park, J; Fox, M; Dragel, G

Based on a preliminary survey of more than 15 oxides and nitrides, four ceramic materials (CaO, MgO, Y{sup 2}O{sup 3}, and BN) were identified as candidates for insulator coating development. These compounds were fabricated by various techniques and exposed to flowing Li at 400-410{degrees} to assess chemical compatibility. Yttrium oxide exhibited excellent corrosion resistance in flowing liquid Li at 400{degrees}C; its corrosion rate was calculated to be 0.042 {mu}m/hr. Resistivity measurements by a standard four-probe method on Y{sup 2}O{sup 3} in air at temperatures between {approximately}450 and 1000{degrees}C, before and after exposure to Li for 675 h at 410{degrees}C, indicatedmore »« less
