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.

  • 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. Current capsule experimentsmore » are examining several different SiC/SiC composite materials at 1000 C. Another issue involves Pb-Li transport between the first wall and heat exchanger. Aluminide coatings on type 316 stainless steel and Al-containing alloys capable of forming an external alumina scale have been studied in capsule experiments at 700 and 800 C for 1,000h. Model aluminide coatings made by chemical vapor deposition reduced the dissolution rate for 316SS at 800 C by a factor of 50.« less
  • For a fusion reactor blanket that contains molten lithium or lithium alloys, forces will arise when the magnetic field is changed and cause pressures in the lithium and stresses in the containment vessels. Previous analyses of this problem assume improperly that the conductive fluid is static. For the present analysis, the conductive liquid is contained in a thin-walled cylinder with a constant (toroidal) magnetic field perpendicular to the cylinder axis and with a time-varying (poloidal) magnetic field perpendicular to the toroidal field. The variables in the liquid are governed by the equations of magnetohydrodynamics and are coupled to the electricmore » current and voltage in the cylinder wall, which are governed by Maxwell's equation and Ohm's law. Formulas are derived for the stresses in the cylinder wall caused by bending moment, torsion, shearing, and ring bending that result from the pressure and viscous shear force on the inside surface of the cylinder and from the electromagnetic body force in the cylinder wall. These formulas are used to calculate the module stresses for the design arrived at in the Oak Ridge National Laboratory (ORNL)/Westinghouse Demonstration (DEMO) Reactor Study.« less
  • Electrochemical oxygen meters with yttrium-doped thoria, yttrium-stabilized zirconia, and calcium-stabilized zirconia solid electrolytes are tested for the measurement of oxygen activity in Pb-17Li eutectic alloy. The proposed breeder blanket fluid for fusion reactors. In this paper the oxygen potentials of the alloy measured by these three meters are compared with the oxygen potentials of the alloy after the addition of lithium oxide and with theoretical values. Zirconium and yttrium metal foils are tested for gettering oxygen from the alloy. The compatibility of the three ceramic materials in the liquid alloy and the stability of the meters for prolonged use aremore » discussed. The influence of oxygen on the corrosion of steels in Pb-17Li is reviewed in light of the oxygen potentials of the alloy compared to thermodynamic data of the ternary oxides of the metal constituents of steels. The possibility of using the oxygen meters to measure the lithium activity of the alloy is also indicated.« less
  • In the last decade, liquid metal (LM) blanket-related key issues, such as the magnetohydrodynamics due to reactor off-normal shutdown, LM velocity two-dimensional effect, manifold three-dimensional effect, insulator coating imperfection effect, and so on, have been investigated in experiments and theoretic analysis in Southwestern Institute of Physics (SWIP). Some results were first observed such as the two-dimensional effect and the instabilities due to insulator coating imperfection in this field. These results also related to the advanced limiter-divertor plasma system. In this paper, we review the progress made by SWIP in this research field.
