Resumo
The primary use of ammonia in nuclear plants is in producing uranium hexafluoride
(UF6), a critical compound for uranium enrichment (U-235). Ammonia’s
widespread use across multiple industries has led to a steady increase
in its production over the years. However, due to its toxic properties, conducting
comprehensive studies on its dispersion is essential, as leaks can pose significant
risks to human health and the environment. Tools like the Areal Locations
of Hazardous Atmospheres (ALOHA) system are employed to model
the dispersion patterns of hazardous gases, enabling the prediction of toxic
substance releases and their spread. This study evaluates ammonia dispersion
in scenarios involving tank punctures or valve ruptures, which can lead to accidental
leaks, particularly in uranium hexafluoride production facilities. The
meteorological factors considered in the dispersion modeling are wind speed,
temperature, humidity, and prevailing wind directions. The results demonstrate
that low wind speeds and high temperatures significantly impact ammonia
dispersion, while fluctuations in humidity have a minimal effect. Furthermore,
the observed findings indicate that the prevailing wind direction in the
site tends to be most commonly from the East-Southeast (ESE). In this direction,
dispersion extends towards vegetated areas and certain uranium hexafluoride
production plant sections. However, the results highlight the wind direction
variability over time, prompting further investigation into additional simulation
scenarios.
