Corrosion is considered in the "min wall" calculation if defined in the input.

The Stress Report is a different matter. The handling of corrosion depends on the code and the load case, as well as the Configuration Directive All_Stress_Cases_Corroded.

So, with All_Stress_Cases_Corroded set to "unchecked", which is the default:

- B31.3 would corrode the SUS and OCC cases, and the corresponding Hoop entry (even though it won't affect the code stress).

With All_Stress_Cases_Corroded set to "checked:

- B31.3 would corrode all load cases, and the corresponding Hoop entry (even though it won't affect the code stress).

CAESAR II does not address Vacuum conditions.
