# Zirconium Alloy Oxidation at High Temperature

Model that incorporates correlations for Zircaloy cladding oxidation through metal-water reactions

## Description

The OxidationCladding model incorporates correlations for Zircaloy cladding oxidation through metal-water reactions at normal operating and at high temperatures. Described processes include outer oxide scale thickness growth and oxygen mass gain. The model is to be applied to the cladding waterside boundary.

## Description

note:Functionality Being Replaced by ZryOxidation

The functionality of OxidationCladding is included in the material ZryOxidation. Use of the ZryOxidation material is preferred over this material.

## Example Input Syntax


boundary = 3
use_coolant_channel = false
temperature = temp
fast_neutron_flux = fast_neutron_flux
#    outputs = all
#    output_properties = 'scale_thickness'
