armi.materials.uZr module

Simplified UZr alloy.

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

class armi.materials.uZr.UZr

Bases: 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.
