3.0 Liquids; Summary
those anticipated under most accident situation (100 ml), and therefore
may be very conservative for many applications.
≤ 50 oC Superheat
Bounding
ARF 1E-2/RF 0.6
50 to 100 oC Superheat
Median
ARF 2E-2/RF 0.7
Bounding
ARF 1E-1/RF 0.7
For superheats greater than 100 oC above the boiling point of the
liquid, the ARF value is 0.33 (MFg)0.91 (where MFg is the mole fraction
of pressurizing gas/water vapor flashed) with an RF of 0.3 if the
calculated respirable release exceeds the 50 to 100 oC superheat value.
Free-Fall Spill
Free-fall spill of aqueous solutions, 3-m fall distance. A distinction is made
between general aqueous solutions and concentrated heavy metal nitrate
solutions such as uranium nitrate hexahydrate (UNH) or plutonium nitrate.
The distinction is gross, with any solution having a density > ~ 1.2 g/cm3
being considered a concentrated heavy metal solution. The highest release
fraction is for aqueous solutions.
Median (aqueous solution, density ~ 1.0 g/cm3)
ARF 4E-5/RF 0.7
Median (conc. heavy metal solution, density
> ~1.2 g/cm3)
ARF 1E-6/RF 0.3
Bounding (aqueous solution)
ARF 2E-4/RF 0.5
Bounding (conc. heavy metal solution)
ARF 2E-5/RF 1.0
Free-fall spills of slurries, 3-m fall distance, <40% solids.
Median
ARF 2E-5/RF 0.7
Bounding
ARF 5E-5/RF 0.8
Free-fall spills of viscous solutions, viscosity >8 centipoise.
Median
ARF 3E-6/RF 0.8
Bounding
ARF 7E-6/RF 0.8
