The Met One Model 1585 bivane is used to measure horizontal and vertical wind direction at area towers. Measurements of turbulence are expressed as standard deviations of fluctuations about the mean azimuth and elevation angle. 1 shows a wind rose for H Area for the period 1992-1996. Since the percentage of time during the period that these conditions occur varies, average wind speed can vary for JFD s of different lengths. Existing Tritium Oxide Data Tritium oxide is sampled biweekly using silica gel which traps moisture from air pumped through a column.
Water is removed from the silica gel by distilling over low heat.
The distillate is mixed with a liquid scintillation cocktail, and counted to determine the tritium oxide concentration of the atmospheric moisture. The location of all of the collection points is shown in Fig. 2. The average distance from the center of the site to the each of the perimeter locations at the boundary is 14500 m. In Fig. 2, Reactor Areas are noted as C, K, L, and P and Separations Areas are noted as F and H. Release amounts for each of the years are shown in Table 1 which also shows a breakdown of percentage release from reactors and separations. Measured air concentrations at the various monitoring locations are shown in Table 2.
