    摘要: A method for fabricating an electrode having extended operating life comprising brazing a cap and adapter to an insulator composed of magnesium oxide-stabilized zirconia (MSZ), calcium oxide stabilized zirconia (CSZ) or yttroim oxide-stabilized (YSZ). Electrodes comprising insulators composed of CSZ, MSZ and/or YSZ are also described.

    摘要: A method and an apparatus for measuring the degree of intergranular stress corrosion cracking protection in the area of the core shroud weldments. Electrochemical potential sensors are attached to the shroud wall and the upper core spray line at locations near the actual weld surface of concern to ensure the accuracy of the electrochemical potential measurements. A working electrode doped or coated with noble metal and a reference electrode are implanted into the reactor core shroud. A throughhole is drilled or machined into the shroud wall at an elevation just below the top guide support ring, i.e., near the core shroud weldments. Then a plug containing the working and reference electrodes is inserted into the throughhole.
