Smith, D L

The measurement of oxygen concentrations in sodium at levels of interest for LMFBR applications is reviewed. Additional data are presented to support the validity of the vanadium-equilibration method as a reference for determination of oxygen concentrations in sodium at levels equal to or less than 15 ppM. Operating experience with electrochemical oxygen meters that have a thoria-yttria electrolyte and a Na--Na/sub 2/O reference electrode is described. Meter lifetimes in excess of one year have generally been achieved for operating temperatures of 352 and 402/sup 0/C, and fairly stable emfs have been observed for periods of several months. 7 fig, 21 references.
