Abstract

The sampling and analytical methods are described more fully in Sturges et al. (2000). In summary, air samples were pumped from consolidated deep snow (firn) at Dome Concordia (eastern Antarctica) in December 1998 and January 1999, from the surface to a depth of approximately 100 m. Air samples were analyzed with a gas chromatograph - mass spectrometer, with a detection limit of about 0.001 parts per trillion (ppt). A diffusive transport model was used to calculate the age of samples as a function of depth. Measurements of SF6 were used to determine the mean age of the firn air by comparison with extrapolated measurements from Cape Grim, Tasmania combined with estimates from industrial emissions (Maiss and Brenninkmeijer 1998, adapted by Sturges et al. 2000). Dates for SF5CF3 are different than for SF6 due to the lower diffusivity of SF5CF3: the SF6 ages were multiplied by the ratio of the free-air diffusion coefficient of SF5CF3 to that of SF6 (1.18). Free-air diffusion coefficients were determined by a semi-empirical formula based on molecular volumes (Fuller et al. 1966). Note that mean ages represent a very wide distribution of probable ages spanning many years, with an increasing spread of ages at increasing depthFormore »« less

Moisture Sensor for Sulfur Hexafluoride (SF6)-filled Circuit Breakers

Technical Report Sauers, I

Measurements at ORNL were made on the Kahn moisture sensor which Doble Engineering wants to evaluate for use in SF{sub 6} circuit breakers. Test conducted at ORNL indicate that vacuum conditions, as might be found in SF{sub 6} circuit breakers prior to filling with SF{sub 6}, could lead to significant changes in calibration, resulting in erroneous readings of moisture content. Similar effects might also be observed in cases where SF{sub 6} byproducts are present, due the reactivity of some of these byproducts with water.
