armi.materials.uZr module

Simplified UZr alloy.

This is a notional U-10Zr material based on [Chandrabhanu].

class armi.materials.uZr.UZr

Bases: armi.materials.material.FuelMaterial

Simplified UZr fuel alloy.

Warning

This is an academic-quality material. Only the 10% Zr-frac properties are present. If you use a Zr-frac other than 10%, these properties will be incorrect. Bring in user-provided materials via plugins when necessary.

name = 'UZr'

enrichedNuclide = 'U235'

zrFracDefault = 0.1

uFracDefault = 0.9

setDefaultMassFracs()

U-Pu-Zr mass fractions

applyInputParams(U235_wt_frac=None, ZR_wt_frac=None, *args, **kwargs)

Apply user input.

_calculateReferenceDensity()

Calculates the reference mass density in g/cc of a U-Pu-Zr alloy at 293K with Vergard’s law

Warning

the zrFrac, uFrac, etc. may seem redundant with massFrac data. But it’s complicated to update material fractions one at a time when density is changing on the fly.

linearExpansionPercent(Tk=None, Tc=None)

Gets the linear expansion from eq. 3 in [Chandrabhanu] for U-10Zr.
