Dense Gas Plume Field Measurements at the Nevada Test Site

摘要

Field experiments on dense gas diffusion carried out at the Spills Test Facilityon the Nevada Test Site are Briefly described, including four 'baseline' releases made in July 1993 and two new series planned for August-September 1995. The first series will target neutral to very stable conditions over very rough surfaces, and the second target diffusion in the same meteorological regions over a very smooth surface, as was used in 1993. Some results of the 1993 tests are given, including mass balance estimates and comparisons of plume dimensions as measured by separate traces (CO2 vs. SF6) and by separate arrays on the same arc (bag samplers and continuous samplers).
