  • Emergency relief from vessels which have high liquid levels or contain reactive chemicals often results in two-phase gas-liquid releases. Some of these two-phase discharges may be routed to separators and other containment equipment, while others may be directed vertically upward to atmosphere. For two-phase streams vented directly to atmosphere, a method is described for estimating the behavior of the discharge. This includes estimation of the initial liquid droplet sizes formed in the vent, jet expansion, air entrainment, and subsequent evaporation of the liquid droplets. A computer model has been developed which takes into account the air entrainment by the two-phasemore » jet and simultaneously solves the equations of motion and heat and mass transfer to the droplets. After the transient simulation of the vertical two-phase release is completed, a conventional air dispersion model for heavier-than-air stack releases is sued to predict the dimensions of the downwind flammable cloud.« less
  • External radiation levels due to positron annihilation radiation from /sup 11/C, /sup 13/N, and /sup 15/O released by the 800 MeV linear proton accelerator at the Los Alamos Meson Physics Facility (LAMPF) have been monitored at a fence-line location both by thermoluminescent dosimeters (TLDs) and high pressure ionization chambers (HPICs). The accelerator is located in irregular terrain consisting of mesas and canyons. Fifteen-minute, accumulated external radiation levels were recorded with the HPICs. Instruments on a nerby meteorological tower concurrently measured wind speed and direction at three levels, temperature at two levels, solar radiation, and rainfall. Real-time radionuclide release rates andmore » stack velocities were measured at the release point with in-stack monitors. This paper presents analyses of short-term radiation levels using HPICs and long-term levels using TLDs. Work being done to develop a computer model to predict external radiation levels based on meteorological data is also discussed.« less
  • Knowledge of particulate or gaseous removal from the atmosphere is becoming increasingly important for more realistic assessment of the risk involved with hazardous atmospheric releases. In transport models, this removal at the air-surface interface, exclusive of that due to precipitation (rain or snow), is often termed dry deposition. Uncertainties exist with respect to the values of the deposition velocity and to the accurate computation of deposition even if the deposition velocity were known. The purpose in this paper is to present a correlation to the deposition velocity and to examine the accuracy of a computational model proposed by Giorgi inmore » which the size distribution is broken into three sections (groups).« less
  • A multi-level, multi-scale approach was used to assess potential impacts to fish health from oil sands water releases. The method used to arrive at predicted impacts involved assembling experimental data on the effects of chronic exposure to oil sands wastewaters on biochemical, physiological and whole-organism endpoint. This information was used to determine no effect levels (NOELs) and lowest effect levels (LOELs) for the suite of fish health parameters used in laboratory experiments (primarily biochemical and physiological measurement endpoints). LOELs and NOELs were compared to modeled concentrations of wastewater in the Athabasca River for five time snapshots. For each time period,more » concentrations were predicted based on mean annual flows and 7Q10 flows (low flows). This comparison was used to predict impacts on biochemical/physiological endpoints. Impacts on at the whole-organism and population-level were determined by comparing what the laboratory data would predict with what was observed in the field. This process was used to draw a conclusion regarding the health and sustainability of fish populations.« less
