armi.materials.leadBismuth module

Lead-Bismuth eutectic.

This is a great coolant for superfast neutron reactors. It’s heavy though.

The data in this file exists for testing and demonstration purposes only. Developers of ARMI applications can refer to this file for a fully worked example of an ARMI material. And this material has proven useful for testing. The data contained in this file should not be used in production simulations.

setDefaultMassFracs()

Mass fractions.

pseudoDensity(Tk=None, Tc=None)

Density in g/cc from V. sobolev/ J Nucl Mat 362 (2007) 235-247.

volumetricExpansion(Tk=None, Tc=None)

Volumetric expansion inferred from density.

NOT BASED ON MEASUREMENT. Done by V. sobolev/ J Nucl Mat 362 (2007) 235-247

density(Tk=None, Tc=None)

Return the density at the specified temperature for 3D expansion (in g/cm^3).

Notes

For fluids, there is no such thing as 2D expansion so pseudoDensity() is already 3D.
